Therefore, alternative leachate treatment is needed. A complex organic liquid called eco-enzyme is the end product of fermentation of organic matter, sugar, and water. This study aims to determine the level of efficiency of eco-enzyme dosage to reduce BOD, COD, and E.Coli content in Benowo landfill leachate water samples. The technique implemented in this study was to dissolve eco enzyme using doses of 13%, 16.7%, and 20% into a reactor containing 7 liters of leachate water. Analysis of BOD, COD, and E.Coli levels was conducted on the 7th, 14th, and 21st day of each treatment. The results showed that the eco enzyme was able to reduce E.Coli but could not reduce BOD and COD of leachate water. The highest E.Coli reduction occurred at a dose of 13% from a concentration of 35000 MPN/100 ml to 1600 MPN/100 ml (95%). The highest decrease in E.Coli occurred on the 21st day of observation from a concentration of 35000 MPN/100 ml to 1600 MPN/100 ml (95%).</p> Cindy Marta Tilana Sri Widyastuti Copyright (c) 2024 Cindy Marta Tilana, Sri Widyastuti https://creativecommons.org/licenses/by/4.0 2024-03-31 2024-03-31 6 1 1 7 10.35970/jppl.v6i1.2075 Potensi Tanaman Sangitan (Sambucus javanica) sebagai Fitoremediator Tanah Tercemar Logam Berat Zn dari Air Limbah Industri Pelapisan Logam https://ejournal.pnc.ac.id/index.php/jppl/article/view/2067 <p style="font-weight: 400;">Phytoremediation is an alternative biological treatment that can be used to reduce soil or water pollutants. Phytoremediation has the advantage of environmentally friendly waste products and a lower budget compared to physical and chemical processes. In addition, phytoremediation has the weakness of long contaminant absorption times, and quite a few plants that are used as phytoremediation agents die because they are unable to survive the high concentrations of heavy metals contained in polluted media. This study aims to determine the ability of the S. javanica (S. javanica) plant as a phytoremediator for soil contaminated with the heavy metal Zn from industrial wastewater. Phytoremediation lasted for 10 days by contacting artificial Zn wastewater with a concentration of 5 mg/L and as much as 50 ml/day on the test plants. The planting medium used was 100% soil (A1) and 50% homogenized soil with 50% manure (A2). Tests were carried out on each part of the plant and growing medium with contact times of 0, 5, and 10 days of phytoremediation. The plant used as a phytoremediator is Sangitan (S. javanica). The optimum contact time in this study occurred on the 10th day of phytoremediation, and the addition of a 50% dose of organic matter in manure had an effect on the concentration of the heavy metal Zn. The accumulation of heavy metal Zn in plant leaves was greater than in roots, with an average BCF of 0.694 for leaves and 0.308 for roots. While the TF value &gt; 1 represents that the Sangitan plant (S. javanica) has the potential to be a phytoremediator and has a high ability to translocate the heavy metal Zn.</p> Kania Salsabilah Nur Rifanda Ahmad Erlan Afiuddin Tanti Utami Dewi Copyright (c) 2024 Kania Salsabilah Nur Rifanda, Ahmad Erlan Afiuddin, Tanti Utami Dewi https://creativecommons.org/licenses/by/4.0 2024-03-31 2024-03-31 6 1 8 16 10.35970/jppl.v6i1.2067 Analisis Kebijakan Pengelolaan Sampah Level Rumah Tangga di Kalurahan Baciro, Kota Yogyakarta https://ejournal.pnc.ac.id/index.php/jppl/article/view/1961 <p><span lang="IN">The city of Yogyakarta is one of the contributors to waste at the Piyungan TPST. Waste production in the City of Yogyakarta in 2021 will reach 327 million tons per day with the largest composition of waste being household waste by 55.2%. Baciro Urban Village is one of the sources of waste with a volume of waste generated of 28.57 m3 per day. This study aims to determine the implementation of household waste management in Baciro Village before and after the Zero Inorganic Waste Movement Program policy, factors related to success and obstacles, and the relevance of waste management implementation to health conditions in Baciro Village. The research approach used is a mix method in the form of a combination of qualitative and quantitative approaches. Quantitative analysis was carried out simply by interpreting the data from the questionnaire results in the form of percentage graphs. The results of data processing and analysis show that Baciro Sub-district has implemented the Circular Letter from Pj. Mayor of Yogyakarta Number 660/6123/SE/2022 regarding the Zero Inorganic Waste Movement and succeeded in reducing the final amount of waste disposed of at TPST Piyungan.&nbsp; The existence of the Zero Inorganic Waste Movement Program has brought better development in household waste management in Baciro Kalurahan. The existence of this program has increased community empowerment and the implementation of the waste bank has been able to be monitored to the JSS (Jogja Smart Service) system. However, there are still challenges in terms of regeneration and the contribution of the younger generation. The inhibiting factors of the waste management process are the limited land and waste sorting bins, while the supporting factors for success are if there is sufficient land available and there is an increase in socialization or counseling regarding waste management. The problem of limited land in the implementation of waste banks poses a risk of decreasing public health.</span></p> Endah Ayu Kusuma Nindya Christy Hamida Nanda Widhianta Qarra Salma Setiawan Yudistira Widinugroho Copyright (c) 2024 Endah Ayu Kusuma, Nindya Christy Hamida, Nanda Widhianta, Qarra Salma Setiawan, Yudistira Widinugroho https://creativecommons.org/licenses/by/4.0 2024-04-03 2024-04-03 6 1 17 28 10.35970/jppl.v6i1.1961 Analisis Indeks Diversitas Vegetasi Hutan Sosial Sukobubuk Kabupaten Pati (Studi Terhadap Habitat Vegetasi Pohon Kayu Jati, Balsa, dan Sengon Hutan Sukobubuk) https://ejournal.pnc.ac.id/index.php/jppl/article/view/2149 <p><span lang="EN-US">Pati Regency, located in Central Java, is known to have many social forests. One example is the Sukobubuk Social Forest. With the management efforts carried out by the Sukobubuk Rejo Forest Farmers Group (KTH), the condition of the Sukobubuk Social Forest has experienced significant improvements. To assess the extent of this progress, an analysis of the vegetation diversitas index in the forest is needed. This research uses a quantitative approach with a diversitas index calculation method which includes frequency, density, dominance, relative number, significant figure index (INP), and diversitas index (ID). The results show that the level of biodiversitas or diversitas index in the dominant woody vegetation habitat in the Sukobubuk forest is still relatively low. This can be seen from the diversitas index figures for the entire vegetation calculated which are still below number 1 (H'&lt;1), with the highest to lowest order being sengon 0.154115951, teak 0.11926885, and balsa 0.078055196. However, forest management by KTH Sukobubuyk Rejo can be said to have experienced quite a development with conservation efforts, this is marked by the start of growth of vegetation habitat, although not yet significant.</span></p> Amrizarois Ismail Bernadia Linggar Yekti Nugraheni Shresta Purnamasari Copyright (c) 2024 Amrizarois Ismail, Bernadia Linggar Yekti Nugraheni, Shresta Purnamasari https://creativecommons.org/licenses/by/4.0 2024-04-03 2024-04-03 6 1 29 35 10.35970/jppl.v6i1.2149 Karakterisasi Alat Filtrasi Air Portable Berdasarkan Variasi Jumlah Absorber Karbon Aktif Limbah Tongkol Jagung https://ejournal.pnc.ac.id/index.php/jppl/article/view/2183 <p style="font-weight: 400;">Sumbawa Regency is an area with soil water content containing lime. There was even lime blockage in the pipe holes used. So this research aims to create a portable filtration device that is cheap and efficient. The aim of this research is to characterize a portable water filtration device with an innovative absorber from corncob waste. The way this research works is the process of carbonizing corn cob waste and then activating it using 0.5 M NaOH for 24 hours. The absorber is then filled into a portable filter with dimensions of 50 cm in length and 4 inches in diameter. Filtration is carried out by flowing the collected well water into the water reservoir through a filter. Tests are carried out on water that has not been passed through a filter. After that, characterization was also carried out on the water that had passed through the filter. This characterization consists of Total Dispended Solid (TDS), Temperature, pH, Ca levels, and turbidity. The TDS value obtained decreases with the increasing number of absorbers used, namely from 203, 163, to 123 ppm. In addition, the temperature of the test water has almost no change. The resulting results were temperatures of 32, 33, and 32<sup>o</sup>C. The resulting pH value shows a decrease with an increase in the number of absorbers used, namely from 8.3; 7.7; 7.3. For turbidity, there was a decrease in the turbidity rate with an increase in the number of absorbers used, namely from 0.29 NTU to 0.3 NTU, and 0.28 NTU. In addition, CaCO<sub>3</sub> levels decreased with an increase in the number of absorbers used, namely from 330 mg/l, 290 mg/l, and 240 mg/l. This value has met the threshold set by PMK No. 32 of 2017.</p> Shafwan Amrullah Sahri Yanti B. As'urin Copyright (c) 2024 Shafwan Amrullah, Sahri Yanti, B.

The large population and heterogeneous community activities on the northern coastal of Palang Sub-District have the potential to become a source of pollution which results in a decrease in seawater quality. The research aim is to analyze seawater quality on the north coast of Palang Sub-District based on seawater quality parameters and the spatial distribution of the pollution index. It is hoped that this research can help local governments to monitor and control water pollution in the area. Sea water sampling was carried out in the dry season for 2 days at high and low tide conditions. This research analyzes the concentration values ​​of BOD, COD, NO3-, TSS, detergent, oil &amp; grease, pH, temperature, and Total coliform compared to seawater quality standards of PP RI No. 22 of 2021 Appendix VIII on Marine Biota. The spatial distribution of the water quality pollution index is the result of interpolation using the Inverse Distance Weighted (IDW) method from the results of measuring test parameters. The Pearson Correlation statistical test was carried out to determine the level of correlation between the parameters selected in determining water quality. The results of the research show a decline in the quality of the northern coastal waters of Palang-Tuban District with several parameter concentration average values ​​exceeding the quality standards, namely pH = 6.9 (QS = 7.0-8.5); TSS = 29.2 ppm (QS= 20 ppm); Nitrate = 0.4 ppm (QS = 0.06 ppm), BOD5 = 54.8 ppm (QS= 20 ppm), COD = 112.5 ppm (QS= 100 ppm). The water quality status shows that the water conditions are moderately polluted (ST1A), lightly polluted (ST1B-ST5B), and good conditions (ST4C &amp; ST5C). Controlling and reducing the pollution load entering coastal waters needs to be carried out to prevent the quality of coastal waters from decreasing further. One of them is by creating wastewater treatment at every fishing port and fish auction.</span></p> Mukamto Euis Nurul Hidayah Susilowati Copyright (c) 2024 Mukamto, Euis Nurul Hidayah, Susilowati https://creativecommons.org/licenses/by/4.0 2024-04-24 2024-04-24 6 1 59 72 10.35970/jppl.v6i1.2161 Pengaruh Penggunaan Bahan Perekat Tepung Sagu, Tapioka, dan Beras Terhadap Daya Bakar Briket Tempurung Kelapa https://ejournal.pnc.ac.id/index.php/jppl/article/view/1750 <p><span lang="EN-US">The need for energy is increasing as the population grows.

On the other hand, the generated waste is only disposed of at the Suwung Final Disposal Site (TPA), without prior processing. However, as of March 2023, the Bali Provincial Government has begun to gradually close the Suwung TPA, due to waste overcapacity, as evidenced by the presence of rubbish piles as high as 25 meters. In response to this, the Badung Regency Environmental Service (DLH) built the Mengwitani Integrated Waste Processing Site (TPST), where waste is processed into Refuse Derived Fuel (RDF) with the aim of reducing waste generation in Badung Regency. This research aims to evaluate the process of processing waste into RDF at the Mengwitani TPST, so that it can be seen how much waste generation can be reduced through RDF processing at the Mengwitani TPST. The method used is a quantitative method, with a mass balance analysis approach. Therefore, it was found that processing waste into RDF was carried out by going through 5 stages of filtering or segregation. So, after processing the waste into RDF, it was found that the potential for waste reduction at the Mengwitani TPST reached 72% every day, and on the other hand, the RDF produced by the Mengwitani TPST had been adjusted to standards, namely SNI 8966:2021.</span></p> Thomas Agung Kurniawan Haniel Yudiar Widhi Handayani Copyright (c) 2024 Thomas Agung, Haniel Yudiar, Widhi Handayani https://creativecommons.org/licenses/by/4.0 2024-05-06 2024-05-06 6 1 94 100 10.35970/jppl.v6i1.2247 Karakterisasi Air Hasil Filtrasi Instalasi Pengolahan Air Sederhana Berdasarkan Variasi Waktu Filtrasi dan Ketebalan Media Arang Ampas Teh https://ejournal.pnc.ac.id/index.php/jppl/article/view/2251 <p><a name="_Hlk165962106"></a><span lang="IN">The increase in population and the development of the industrial sector have resulted in water pollution and a decrease in the quality of clean water.

The research carried out experimentally in laboratory aims to determine the effect of biocatalytic enzyme treatment from fruit and vegetable peel (concentration variations of 5%, 10%, 15%) on pH, chemical oxygen demand (COD) levels, total suspended solids (TSS), and total coliforms of hospital liquid waste. From the research results, it was found that the addition of biocatalytic enzymes was very effective in reducing the total coliform concentration. The highest reduction in coliforms occurred with the addition of 15% enzyme, where there was a decrease from 1600 MPN/100 mL to 500 MPN/100 mL at a digestion time of less than 24 hours. After a digestion time of 2 days, no coliforms were found in the wastewater samples. However, there was a decrease in pH and an increase in TSS and COD concentrations which did not meet quality standards after being treated with enzymes at all concentration variations. The profile of changes in TSS and COD concentrations shows a decreasing trend with an increase in digestion time of 1 to 3 days, the values ​​obtained will still exceed the TSS and COD quality standards (30 mg/L and 100 mg/L). Meanwhile, the waste pH gradually increased with increasing digestion time up to 3 days at enzyme concentrations of 5% and 10%, namely 3.5 and 4.8.
