ANALISA PENGGUNAAN SILICON CONTROLLED RECTIFIER PADA ELEKTROPLATING TEMBAGA/BAJA KARBON RENDAH
Electroplating
Copper
Low Carbon Steel
Silicon Controlled Rectifier.
Electroplating is one of the engineering improvements in the characteristics of metal materials. Copper coating is a pre-coating before further coating for steel. The surface area of the material is in line with the strong current requirements required for the normal coating process. However, too much current flowing into the cathode results in erosion at the anode. Silicon Controlled Rectifier (SCR) is a component made of semiconductor silicon. It has a function as a controller or switch. Silicon Controlled Rectifiers can be used to reduce coating currents in copper electroplating. The setting of the coating current can be done on copper electroplating of low carbon steel cathodes with a cross-sectional area of 7500 mm2 of 4.5 A; 5 A; 6 A; 6.5 A and 6.7 A. The best copper coating results with a 10 minute coating time are shown in the current 6.5 A with a coating mass of 1.11 grams and 1.06 grams. This proves the need for a reduction in the maximum flow so that optimal coating is achieved.

Investment is a principle thing in the business world, because investment is one source of capital that can be owned by capital holders. The public still has a perception that shares or capital markets or exchanges are something complicated, expensive and have high risk. A survey conducted by OJK in 2012 explained that the level of literacy and financial inclusion of Indonesian people was still relatively low at only 3.7 percent literacy and accountability. Only 0.11 percent is inversely proportional to the number of Indonesians whose numbers are always increasing every year. Let's Save Stocks is a campaign that was inaugurated in 2015 by Indonesian Vice President, Yusuf Kalla in enhancing the role of the community in shares. An interesting promotional media is needed to introduce shares to the public, one of which is an animated film that is able to be consumed by people of all ages, education and economics. Moreover, motion graphic is a technique that is able to make still images to move and be interactive.

Universities are educational institutions that cannot be separated from student service activities, especially student letter services. Currently, student letter service activities at the TEDC Polytechnic Bandung are still using conventional methods. Students who wish to make certain letter submissions must often fill in data on paper forms to make letter submissions. The problems that occur are the data is not well organized, the large number of papers that must be printed for service forms of various kinds of letters and also service officers still have to enter data on the form into letters submitted by students manually. Based on this problem, it is necessary to create a student letter service administration system to manage various student letter submissions. The method used in this research is waterfall. The database design uses MySQL and the programming languages used are PHP and Java. The result of this research is that there is an administrative system that is able to manage student letter submission data, starting from submission, letters being processed, to giving notification to students that the letter has been processed. From the test results, 82.8% of respondents agreed that the system was able to manage student letters.

isuzu panther 1996
This study aims to analyze the ability of the copper honeycomb type DPF to the engine performance of diesel engines. The object of research was the 1996 Isuzu Panther engine, which was equipped with one standard exhaust and three experimental exhausts with DPF technology with a variety of mesh sizes 20, 15, and 10 mm. The findings of this study are that the DPF 10 mm is the best variation when compared to the other two variations in terms of increasing engine performance. The reason is that the smaller the mesh, the better the trapping of fine dust particles. Besides, the temperature inside the DPF is also increasing. Also, the use of the right casing design will make the turbulence of the exhaust gas flow lower. Furthermore, the temperature continues to grow, and the little turbulence of the exhaust gas flow will cause self-burning in the DPF. The occurrence of self-burning will have an impact on the complete combustion process, which affects increasing torque and engine power by 2.29-11.68% and 2.94-11.93%, respectively, when compared with standard exhaust.

diethyl ether
Increasing consumption of fossil fuels, depleting oil reserves and increasingly expensive fuels have forced the use of alternative fuels. Diethyl ether (DEE) can be used as an alternative fuel because it has a high cetane number, low viscosity, and high oxygen content. This observation was carried out to determine the effect of the addition of Diethyl ether on 20% diesel-jatropha fuel mixture to the torque and power produced. Tests carried out on a 4JB1 type direct injection diesel engine with a constant speed of 2500 rpm. The DEE volume used is 5%, 10%, and 15% is volume-based. The test results show 20% jatropha content produces lower torque and power compared to pure diesel fuel (D100). Also, the addition of DEE to 20% diesel-jatropha fuel produces low torque and power but the value is higher than 20% of diesel-jatropha fuel. The highest torque and power reduction trends occurred in the use of DJ20 fuel by 0.0448% when loading 25%. While the lowest decrease in torque and power occurs in the DJ20DEE15 fuel by 0.0112% with 100% loading compared to D100 fuel.

Plastic waste is one of the environmental problems in Indonesia. Plastic waste is a type of waste that is difficult to decompose, so it needs special handling for processing the problem. One alternative offered is by making a plastic chopper machine. One of the manufacturing of a machine is to design and analyze the components used. The blade is one of the important components of a plastic chopper. Model simulation of the blade itself needs to be done to analyze the performance of the blade during the performance of the machine. Simulation modeling is done using CAE software.. The form of meshing in the blade model is using tetrahedral and the meshing ratio is close to 1. The results obtained from the blade modeling process are the maximum Von mises stress on the loading of 300N, 500N, and 700N respectively at 6.752 x 10-3 MPa, 2.845 x 10- 3 MPa and 1,575 x 10-3MPa. While the amount of displacement in the variation of loading 300N, 500N, and 700N respectively has a value of 6.752 x 10-2 mm, 1.125 x 10-1 mm and 1.575 x 10-1 mm. The safety factor in this simulation is produced which has a value of 15, which means it is safe for all loading variations because it has a value of more than 1.

Ocean wave power plant is one of the plants that uses sea waves as the main energy. Although the amount of energy is abundant, in Indonesia the use of sea waves as electricity generators is still small. This is due to the lack of human resources to manage the wave energy of sea water. Many research studies on the Oscillating Water Column have been carried out, but it is only limited to a potential or feasibility study to be installed on the coast. Therefore, the focus of this research is to design a sea wave power plant with an oscillating water column system. The working process of the tool begins by adjusting the pwm to drive the motor power window which is connected to the wave arm. When the wave arm moves back and forth, it will produce artificial ocean waves. Artificial waves in the chamber produce compressed air, the air produced is used to rotate the turbine blades that have been connected to the generator to produce electrical energy. The greatest voltage and current is obtained when the wind speed reaches 7.7 m / s and the largest pulley rotating speed reaches 31,9 rpm at the 17 cm water level, which is 3.03 V DC and 6,07 mA. The test results prove that the potential of water waves can be used to generate electricity The development of the capacity of ocean wave power plants can be done by changing the dimensions of the turbines and increasing the capacity of the generator.

cable 20 kV
In the 20 kV distribution system, insulated cables and conductors of fibrous and solid copper are used. Some problems on 20 kV system occur due to the line length of the lines. This obstacle occurs in the cable, mostly at the cable connection. To overcome this problem, a cable connection technique known as extothermic welding was developed. However, in this process, it is also undeniable that there is a thickening due to the contact which causes the uneven distribution of the electric field in the cable. To see the distribution of the electric field on the surface of the cable that was carried out by the exothermic welding process, a simulation was carried out in FEMM 4.2 with 3 final connection conditions, namely perfect jointing, jointing with a thickness of 0.5 mm and jointing with a thickness of 1 mm. As a result of this imperfect connection, the distribution of the electric field on the surface cable is uneven. There was a high electric field surge at the ends of the cable joint with a thickness of 1 mm and a reduced surge in the cable with a thickness of 0.5 mm at the joint. In a perfect connection, the distribution of the electric field occurs evenly.

The conventional cooling process was chosen because of the better estimation of manufacturing times and lower manufacturing costs. One alternative to minimize the decline in quality in plastic products is by using a conformal cooling process. This study will compare the contours of the fluid flow pattern between conventional cooling channels and conformal cooling channels. Case study on a box-shaped product made of PP material which has a melt temperature of 205 ° C. 3D product images were made with Solidwork 2017 software and process simulation using fluent 19.0 software. The results showed that the temperature flow pattern in the conformal channel resulted in a temperature absorption of around 303.2K while the conventional cooling channel was around 302.5K. Then the coolant channel that experiences high pressure drop occurs in the conformal cooling channel around 88888.9 pascals and the conventional cooling channel around 355555.6 pascals.

Shot peening is a surface treatment method at low temperature by shooting steel balls that are continuously adjusted for pressure and speed until plastic deformation is produced. The optimal parameter of the shot peening process was tested with the taguchi distribution. The factors and levels used are processing time, shooting distance and air pressure used in the shot peening process. Observations were made by looking at changes in surface roughness, thickness reduction, hardness levels, wear and changes in the microstructure of ST 45 steel material. The greatest hardness of 240.39 HVN was obtained at 10 minutes, a distance of 10 cm and a pressure of 9 kg / cm². The results of the surface wear test with the smallest value of 0.00039 mm³ / kg.m were obtained at 5 minutes, a distance of 10 cm and a pressure of 7 kg / cm². The results of the microstructure test showed that the change in the grain size of the microstructure of the material became flatter and smaller, the gravity shot peening method improved the mechanical properties of the ST 45 material.

The rocket motor tube is the main component of the Dextrose rocket. This paper aims to investigate the effect of tube length and fillet radius on the safety factor of a dextrose rocket motor tube using Ansys Workbench. The Dextrose rocket tube uses Al 6063-T5 material with an outer diameter of 32 mm, a wall thickness of 3 mm, and internal pressure of 5 MPa. The rocket motor tube length is varied by 200, 250, 300, and 350 mm. The fillet radius uses variations of 3, 4, and 5 mm. The analysis was carried out using the finite element method with the help of Ansys Workbench. The simulation results show that the safety factor does not have a significant effect on changes in the length of the rocket tube. The safety factor increases as the fillet radius increases.

AUC.
Dynamic signature verification by using histogram features is a well-known signature forgery detection technique due to its high performance. However, this technique is often limited to angular histograms derived from vectors containing two adjacent points. We propose additional new features from the X and Y histograms to overcome the limitation. Our experiments indicate that our technique produced Under Curve Area AUC values 0.80 to detect skilled forgery and 0.91 for random forgery. Our method performed best when the verification system uses 12 of the most dominant features. This setup produced AUC values of 0.80 to detect skilled forgery and 0.93 for random forgery. These results outperformed the original technique when the X and Y histogram features are not used that produced AUC values of 0.78 to detect skilled forgery and 0.90 for random forgery.

Air Glubi Village which is one of the villages in the Bintan Pesisir sub-district, Bintan Regency, Riau Islands province, is one of the villages that is one of the outer islands of Indonesia which still has no electricity, and is difficult to reach by PLN. In this village, there is no water source available for PLTMH, so the alternative for electricity supply in Air Glubi Village is a centralized PLTS. This paper discusses the planning of centralized PLTS in Air Glubi Village, Bintan Pesisir sub-district, Riau Islands province. Because the availability of land, the economic capacity of the population is limited, optimization is needed. This optimization is used to get the optimum electrical energy output with these various limitations. From primary data, electricity demand in the village is 62492 Wh per day. The optimization resulted in a centralized PLTS design with an off grid type with a capacity of 37 kWp. The main component is a solar module made of monocrystalin with a capacity of 200 Wp each, totaling 186 modules. The battery uses VRLA 200 Ah each, totaling 250 batteries. The change of Dc electricity to AC is carried out by utilizing an inverter with a capacity of 10 kW totaling 4 pieces. To build a centralized PLTS in Air Glubi Village need costs Rp 2,983,902,171.

The high octane number and oxygen content of butanol can improve combustion more completely and the residual gas resulting from engine combustion is more environmentally friendly. This study examines the effect of adding 5% to 15% butanol at 5% intervals on a gasoline engine with an EGR system with premium fuel on emissions and exhaust gas temperatures. The exhaust gas analyzer was used to measure the combustion gases. Exhaust gas temperature was measured using a thermocouple mounted on the exhaust manifold. The mixture of P85B15 reduced CO levels by 68.11% and HC by 37.50% compared to P100. However, CO2 emissions and exhaust gas temperatures increased. The use of hot and cold EGR generally increased engine exhaust emissions. However, the exhaust gas temperature decreased by 4.72% when the engine used cold EGR and 1.33% when the engine used hot EGR.

The improvement of the sales system not only focuses on the advantage result of the sales transaction but also can use another parameter to improve it. One of a parameter used is commission. Giving commissions to the salesperson can improve their work performance and have an impact on increasing sales targets. Based on the study literature, the problem faced by the company is the discrepancy of commission. It canbe affected by several factors such as the commission system are not integrated with the main system, improper formula, or there are many systems used in the company so it the staff are difficult to integrate the system. For example, the company using Odoo ERP to support sales transaction and use commission information system separately. The salesperson must integrate sales data into both of the systems. It can affect the time delay of decision commission. Based on the problem above, we propose a prototype commission system that integrates with Odoo12. The salesperson does not need to integrate data manually into the system because it automatically integrates into the system. This study uses a prototyping model as a software development method. The results show that the commission system can implement on the Odoo12 ERP to decide commission to the salesperson. 70% of respondent agree that system has able to use in order to setting up commission module on Odoo

The 1.5 inch pipe rolling machine utilizes an electric motor to drive the pipe holder and a 2ton jack as a pipe press. Although the roller machine is widely used in conventional workshops by using human power, it causes the pipe rolling time to be long and the machine user gets tired quickly. This is due to lack of resources to think about developing and improving the performance of these machines. Therefore, the focus of this research is the design of a 1.5 inch pipe rolling machine using an electric motor as a drive and a 2 ton jack as a pipe press. This research aims to produce a design and machine for 1.5 inch pipe rolling and to help accelerate the pipe rolling process and reduce worker fatigue. This pipe rolling machine consists of several components, namely, the engine frame, electric motor, gearbox reducer, chain-sprocket, shaft, pipe drive wheel, hydraulic pump and so on. The working process of this machine begins by preparing a 1.5 inch x 3 meter pipe then the pipe is positioned above the drive wheel, lowers the upper pressure wheel to the desired depth with a 2ton jack power, turn on the electric motor and press the button to roll the pipe back and forth and so on. up to pipe roll size as needed. The stages in making this machine are design, detailed drawing, manufacturing process, quality control, assembly and testing, data retrieval and data analysis. The research resulted in drawings of the design and manufacture of the machine, the calculation of the rotational speed of the machine for optimal rolling obtained 20.46 rpm and an average pipe rolling time of 6.80 minutes for one workpiece. This machine can still be optimized by adding a workpiece movement limiter when rolling.

Problematic Students
One of the factors that affect the comfort of the learning process at school is students who violate school rules. To maintain school order, it is necessary to give punishment as stipulated in the school's decision. Decision Support System can be implemented as a media to support decision making in giving punishment to problematic students. In general, punishment for problematic students uses a point system according to the type of violation. However, the calculation and management process is still done conventionally which is prone to human error. Engineering punishment is very likely to occur due to the like and dislike factor. This of course causes the school's decision to be wrong. This study aims to make a Decision Support System application to determine the level of punishment for problematic students using the Simple Additive Weighting (SAW) method and the Decision Table. The weighting of violation points is based on three criteria, namely academic violations, aesthetic violations, and ethical violations. The results showed that the calculation of the weighted score of each type of student violation became more precise.

Optimalisasi Kapasitas Rooftop PV System Skala Rumah Tangga di Perumahan
Prima Dewi, Riyani
Hazrina, Fadhillah
Widianingsih, Betti
One of the renewable energies in Indonesia is solar energy. The geographical condition of Indonesia, which is a tropical country, is one of the advantages it has for applying solar energy. The Indonesian government is gradually regulating the population system for Solar Power Plants (PLTS). The resident system is in demand because of the advantage that it can be connected to the PLN grid and used as an energy reserve. The installation of rooftop PLTS both in government buildings and on the roofs of houses has now become a common trend in the community as a form of participation in the use of New and Renewable Energy (EBT). Before installing PLTS Roofs, it is necessary to determine in advance how much capacity will be installed. This is also related to the community's question, what is the percentage of electricity costs if PLTS roofs are installed in bulk. These designs and calculations are generally carried out with the help of simulations. To discuss these problems, in this article, we will discuss a simulation of the potential for electrical energy generated from rooftop solar power plants in Cilacap Green Smart Living housing. The simulation was carried out with the help of the SolarGIS PV lunar device. Analytical calculations are carried out by software based on input of regional location and solar irradiation. SolarGis will calculate the daily output power generated by the rooftop PV mini-grid and the average monthly and yearly power. The simulation results show that one house with a daily energy requirement of 13 kWh by installing a rooftop PLTS with a capacity of 3 kWp, the demand for electrical energy imported from the PLN network to the house is only 7.8% in one year.

Suhaman, Jali
Data from Bank Indonesia shows that the rupiah exchange rate against dollar weakened at the beginning of the Covid-19 pandemic. This exchange rate volatility is an important problem in the Indonesian economy. Therefore, the prediction model for the exchange rate against the dollar is needed during the Covid-19 pandemic to predict the exchange rate during the Covid-19 Pandemic. This study is proposed to compare the prediction of the rupiah exchange rate against the dollar using the GA-based Neural Network algorithm and the PSO-based Neural Network algorithm. Initially the data was collected in the period 2019 to 2021, then the data is preprocessed. Validation used the k-fold validation technique with a ratio of 70:30, while the evaluation is carried out with the output of RMSE. The results showed that the performance of PSO and GA was the same, namely 0.020 +/- 0.006.

Setyono, Gatot
Kholili, Navik
Rakhmadanu, Yanuariza
The optimal approach to enhance solar panel efficiency and decrease the degradation rate is to lower the temperature range of the surface area. It will be applied by allowing the panels/modules to be cooled and lessening the heat stored in the solar cells through an operation. In the research using experimental methods, the solar panels used have a capacity of 100 WP as a source of micro-power generation, the angle of inclination of the panels is adjusted with variations of 150, 200, and 250. The cooling system uses water, the process of draining water using a submersible pump mounted on a reservoir Water flows to all surfaces of the solar panel and circulates continuously when operating. The experimental outcomes show that the cooling process utilizing water has reduced the temperature operating of the solar panels. The decrease in average temperature occurred in all variations of 23%. The cooling process significantly affects the output power and operational efficiency; circulating cooling can increase the scale of incidents solar radiation on the solar panel due to the refractive effect of the water layer and keep the surface of the solar panel clean from dirt and dust. Output power and operational efficiency have increased in almost all variations in the angle of the solar panel tilt (150, 200, and 250), output power has increased by an average of 22%, and efficiency has increased by on average of 2%

The aim of this research is to test and compare the performance of the ELECTRE method with MOORA in decision making. By using the attribute weighting process, namely the calculation of Information Gain in both methods, the attribute weights are obtained systematically and objectively, therefore they are no longer determined by the assumptions of decision makers. The test data instrument used is a dataset from the UCI Machine Learning Repository, namely the Fertility Dataset which is data on the level of sperm fertility concentration with 100 data records, 9 attributes, 1 class variable and the data set is multivariate. The results of testing the ELECTRE and MOORA methods in this study indicate that the two methods have differences in the results of ranking the best alternative for sperm fertility concentration levels. The ELECTRE method produces A2 as the best alternative, while the MOORA method produces A16 as the best alternative. Then in terms of program execution time, the MOORA method is faster, namely 0.02 seconds, while the ELECTRE method execution time is 1.88 seconds.

SIM 900 L module
The rainfall in the Cilacap region is high, about 80-100mm in October-March. The high rainfall that causes the overflow of river water is unpredictable. The high water discharge is not realized until the river water overflows and causes flooding. Therefore, a river water level monitoring system is needed to detect river overflows early. This tool uses a solar cell as a power supply. The monitoring system is divided into two points of river water level monitoring system with a distance between points for the laboratory scale stage, which is 100 meters. Sensors that measure the height of river flow are ultrasonic sensors. The sensor results are processed by microcontroller and SIM 900 L module to be sent to the database. When the water level is in the Alert level 3, the buzzer will sound as a warning. The ultrasonic sensor test results have a very small error. Sensor 1 has an average error of 0.00023% and ultrasonic sensor 2 has an error of 0.00016%. The system is able to transmit river water level data that can be accessed through the website.

The Cilacap region, Central Java, Indonesia is a coastal area that is overgrown with nipa palm trees, making it one of the potential local natural resources to be exploited. Utilization of this plant has been carried out for the fields of food, energy, clothing, pharmaceuticals, and furniture, but as an anode material for lithium-ion batteries is still being researched. Studies on lithium-ion batteries in Indonesia in particular have not started long ago so that research in this field is still limited and few in number, but the development of lithium-ion batteries has become one of the national research priorities in the field of new and renewable energy sources as stated in the Indonesian national research master plan (RIRN) for the period 2017 – 2045. This study was conducted to examine the potential feasibility of activated charcoal from nipah shells as anode material for lithium-ion batteries. The feasibility test parameters studied in this study include water content, ash content and adsorption capacity stated as iodine and methylene blue number which are the basic characterizations for activated charcoal referring to SNI 06-3730-1995. The nipah shell carbonization process was carried out in the presence of oxygen at an optimized temperature of 210 oC with a 1 hour time interval variation from 3 to 8 hours, followed by an activation process using a strong acid, namely HCl with a concentration of 2 M. The experimental results showed the average value of moisture content, ash content, iodine, and methylene blue number are 12.5%, respectively; 1.75%; 2515.9161 mg/g; and 97%, all of which are above the quality standard values, so the conclusion from this study is that activated charcoal from nipah shell has basic characteristics that have the potential to be further developed, including as raw material for lithium-ion battery anodes.

Metallic-based materials are commonly used as bone plates as well as orthopedic implants, due to their mechanical properties. This study aims to perform a finite element analysis based on three-point bending test data according to the ASTM F382-99 standard. The dimensions of bone plate material was 120 mm x 14 mm x 5 mm (length x width x thickness) with 6 and 10 screw holes. The load given to the plate analysis was 986.89 N with element size of 0.55 mm. The hexahedron elements have the total number of 62,179 elements for 6 holes and 62,960 elements for 10 holes. The total number of elements of the tetrahedron were 63,609 elements for 6 holes and 64,822 elements for 10 holes. Also, finite element analysis for plates with 6 holes and 10 holes using hexahedron elements yielded a total deformation of 6.1963 mm and 6.7852 mm, respectively. Furthermore, the tetrahedron element for plates with 6 holes and 10 holes resulted in a total deformation of 6.1762 mm and 6.7651 mm, respectively. Based on the above data, it can be concluded that the finite element analysis calculation for bone plate using hexahedron elements is more accurate when compare to the tetrahedrons.

The Savonius turbine has a simple construction making it easy to build. The weakness of the conventional Savonius turbine is that there is a negative torque due to the presence of blades that are opposite to the flow direction. Negative torque can be reduced by placing a curved plate at the front of the turbine. The purpose of this study is to analyze the use of a curved plate deflector for the performance of a two-blade Savonius vertical axis air turbine. The research was conducted by varying the curvature of the deflector, namely 1/4 circle, 3/8 circle and 1/2 circle experimentally. The test results show that the addition of a curved plate deflector improves turbine performance compared to without using a deflector. Of the three variations of the deflector, the 1/4 circle deflector has the highest performance with a power generated of 0.266 Watt and a power coefficient of 0.169 at 113 rpm.

The interest of hotel visitors has decreased since the Covid-19 pandemic. So it is recommended that hotels implement Customer Relationship Management (CRM) which has three stages: getting new customers (Acquire), improving customer relationships (Enhance), and retaining customers (Retain). However, hotels currently do not have practical service applications that help to maintain the relationship between hotel management and consumers, so it requires research that implements E-CRM by designing a prototype of web-based Hotel customer service applications. This study aims to standardize hotel customer service applications that implement E-CRM. It uses qualitative research methods by applying the prototype system development method. The research contribution is to make an E-CRM prototype in a hotel customer service application with several features such as complaints, testimonials, promotions, and point redemption. Based on experiments and testing from a user using UAT and interview, the implementation of E-CRM using a prototype of web-based Hotel customer service applications helps the staff to find customer complaints. The promotion feature helps staff add promotional information that appears on the website's front page. Hotel customers can use the feedback feature in complaints, testimonials and redeem points exchange with prizes. In future research, sentiment analysis on hotel customer reviews using a classification algorithm can be carried out.

The disease has a high risk of maternal and fetal death, so there is a need for early detection of mothers at risk of preeclampsia. Early online detection of preeclampsia is the best solution during the Covid-19 pandemic by analyzing the influencing factors. The purpose of this study is to build an expert system for early detection of preeclampsia in pregnant women using the Certainty Factor method and the waterfall system development model in order to provide the possibility of pregnant women suffering from preeclampsia. Testing the accuracy of 30 medical record data for pregnant women resulted in a system accuracy level of 90%, while usability testing resulted in a user satisfaction level of 55 with the System Usability Testing (SUS) score criteria being "Poor", therefore improvements are needed on expert system in the future.
