<p><span lang="IN">Forest is a stable ecosystem, which has a balance between producers, consumers and decomposers. Where, the forest itself has the ability to provide unlimited natural resources. However, optimal and sustainable forest management and utilization is needed in order to have a forest that has adequate environmental carrying capacity, with the aim of guaranteeing the role and existence of the forest. The Tinjomoyo City Forest which is located in Semarang City has an area of 57 ha, with the area of green space in Semarang City being 10,966 ha, out of the 37,367 ha area of Semarang City. Thus, it has reached 30% of the need for green space in the City, if based on Law no. 41 of 1999. Therefore, because the position of the City of Semarang, which has a large green space, has complied with the Law, it is very important to maintain its existence. In this research, it was carried out by direct observation method, which included observation, inventory, and volume calculation. After carrying out an inventory and data processing, it was found that the Tinjomoyo City Forest had a volume of wood reserves of 4,548,600 m<sup>3</sup>. So with the knowledge of these large enough wood reserves, it is necessary to maintain, manage and utilize forest resources optimally and sustainably. With the aim, to maintain the availability of wood reserves in the Tinjomoyo City Forest.</span></p>Paskhalis B. TimoroYuvens D. PerkasaBonifasius B.S. WibowoThomas A. KurniawanAmrizarois Ismail

<p><span lang="EN-US">Tomato (Solanum lycopersicum) is classified as a climacteric fruit that is easily damaged, especially during the storage and shipping process, so proper postharvest management is needed. Postharvest management of climacteric fruit can be overcome by inhibiting the process of respiration and transpiration using activated charcoal. Activated charcoal works by absorbing ethylene gas during the respiration process. This study aims to analyze the use of bidara activated charcoal variations as an inhibitor of tomato ripeness and to examine changes in fruit quality during the 10day storage. The research used One Way Anova analysis with one factor of variation of activated charcoal with control treatment, 1gr, 3gr, and 5gr. Parameters tested were weight loss, Total Soluble Solid, and vitamin C. The use of bidara activated charcoal on tomatoes got the best results in the 5gr treatment with a weight loss value of 0.46%, 0.10 <sup>o</sup>brix total dissolved solids, and 18.93% vitamin C. Bidara activated charcoal had an effect on weight loss and total soluble solids but had no effect on vitamin C content. Bidara wood activated charcoal can be developed into an absorbent material for tomatoes.</span></p>Lalu Heri RizaldiNi Komang Hestiningsih

<p><span lang="EN-US">Waste transportation in East Balikpapan District currently does not have an effective waste transportation route, this has resulted in not optimal waste transportation, which is indicated by the large amount of waste accumulated at the TPS. Based on these problems, East Balikpapan requires optimizing waste management, especially in waste transportation, to reduce the accumulation of waste in TPS, which can cause environmental pollution. The research procedure used is to optimize the Waste transportation route in the East Balikpapan District using a qualitative descriptive method. Through this method, this research can improve the waste transportation system at the research location by providing improvements that are modelled using Geographic Information Systems (GIS). Determination of the most effective transportation route will be adjusted to the condition of the road being traversed, the distance travelled and the speed of the vehicle in the waste transportation process as well as the time it takes for the SCS (stationary container system) system to transport waste. Based on the existing conditions, transporting two dump trucks takes 7 hours, and one dump truck takes 6 hours and 30 minutes, with a distance of 69 km, 68 km and 104 km. The distance and time for transporting waste under existing conditions can be optimized with alternative routes, optimization results for the three dump truck fleets, namely the distance of 68 km with a time of 6 hours, a distance of 46 km in 5 hours and a distance of 68 km with a time of 5 hours in 2 trips per day.</span></p>Iqoh Andini PutriIntan Dwi Wahyu Setyo RiniRina Noor Hayati

<p><span lang="EN-US">Natural resources (SDA) are wealth that not every country in the world has. Natural Resources are divided into several parts according to their classification, including Mineral Resources. Mineral Resources are natural resources that contain minerals and mining materials that have economic value. The materials contained therein are usually used as high-value production materials, this is what causes mineral resources to sometimes be used inefficiently. One of the mineral resources in Indonesia is in Central Java Province, precisely in the city of Semarang, which is commonly known as "Brown Canyon". The "Brown Canyon" area is rich in natural mineral resources which are ultimately used by the community as work land in the form of mining, on the other hand, "Brown Canyon" is also used as a natural tourist attraction. The mineral content in the form of sand and stone in this area has a promising economic value for the surrounding community, but behind this economic value the existing content or reserves are not yet fully known. In this research the author will analyze the current conditions of the "Brown Canyon" area, especially in terms of the availability of mineral resources in the area using qualitative and survey methods. The results of the calculation of mineral reserves were obtained at 1,918,800 tons. Mineral reserves in the form of stone and sand in Brown Canyon will be exhausted within 17 years with annual mineral resource extraction of 108,000 tons.</span></p>Clara Angelina Kusuma DewiAlberta Kristi PurwandariDesi Febrina MaharaniMaria Beneficia DivinaAmrizarois Ismail

<p><span lang="EN-US">Soil dust is the most difficult object of research to find in applications, even though it is rich in silica, silicate, and aluminosilicate compounds, which are widely known as adsorbents. The physical and chemical characteristics of compounds in which the main framework is the oxides of silicon and aluminum in the material are usually related to their Si/Al mole ratio. This study aims to study the effect of changes in the levels of silicon, aluminum, and related elements in alkaline or acid-treated soil dust (DTBA) in adsorbing methylene blue (MB).</span> <span lang="EN-US">The difference in the composition of the elements in DTBA is expressed in terms of the mole ratios of silicon to aluminum, (Si/Al)<sub>mole</sub>, the ratio of moles of silicon to the number of moles of aluminum and iron, (Si/(Al+Fe))<sub>mole</sub>, the ratio of moles of silicon to the number of moles of aluminum, iron, and calcium, (Si/(Al+Fe+Ca))<sub>mole</sub>, and the mole difference of silicon to aluminum, (Si</span><span lang="EN-US">-</span><span lang="EN-US">Al)<sub>mole</sub>.

Through linear and non-linear regression (2nd order polynomial), plotting of the concentration of adsorbed MB to (Si–Al)<sub>weight</sub> had the highest correlation coefficient (R<sup>2</sup> = 0.9767), better than (Si/Al)<sub>mole</sub> (polynomial 2, R<sup>2</sup> = 0.5177), (Si/(Al+Fe))<sub>mole</sub> (polynomial 2, R<sup>2</sup> = 0.7940), and (Si/(Al+Fe+Ca))<sub>mole</sub> (linear, R<sup>2</sup> = 0.7996) or the same based on percentage of weight, (Si/Al)<sub>weight</sub> (polynomial 2, R<sup>2</sup> = 0.9105), (Si/(Al+Fe))<sub>weight</sub> (polynomial 2, R<sup>2</sup> = 0.6649), and (Si/(Al+Fe+Ca))<sub>weight</sub> = (polynomial 2, R<sup>2</sup> = 0.5601). From a number of optimizations, the adsorption of MB on DTBA was close to the Langmuir and Redlich-Peterson isotherm adsorption model, which describes that there was one layer of MB adsorbate on the surface of DTBA. With this result, soil dust resulting from alkaline or acid treatment can adsorb MB on its surface, which is determined most by the difference in the weight of silicon to aluminum.</span></p>Dede SuhendarFresa Agustini

<p><span lang="EN-US">Laundry waste is a pollutant that has pollutant parameters such as TSS and COD. One alternative processing is flocculation-coagulation using synthetic coagulants. The advantage of synthetic coagulants is that they are able to remove high concentrations of pollutants, but the disadvantages are that they produce quite a lot of chemical sludge and the pH of the water becomes acidic because the higher the concentration, the more coagulant is used. Previous research explains that chitosan at low doses has good penyisihan efficiency so that when combined with PAC it is hoped that it can increase penyisihan efficiency with less sludge.</span> <span lang="EN-US">The purpose of this study was to determine the optimum dosage and composition for PAC and chitosan coagulant composites using the Jar Test. The Jar Test method for determining the optimum dose uses fast stirring at 140 rpm for 2 minutes and then slow stirring at 60 rpm for 15 minutes and settling for 30 minutes. Determination of the optimum dose by adding a coagulant composite of 300 ppm, 500 ppm, and 700 ppm and by varying the composition at each dose, namely 1:1, 1:3, and 3:1 between PAC-chitosan. The best conditions from the study obtained an optimum dose of 700 ppm and an optimum composition of 3:1 between PAC and chitosan resulting in COD and TSS penyisihan efficiencies of 70.04% and 90.82%.</span></p>Ahmad Erlan AfiuddinUlvi Pri AstutiTanti Utami DewiMirna AprianiNovi Eka MayangsariNabillah Rodhifatul Jannah
