<![CDATA[Masalah akibat kepadatan penduduk adalah meningkatnya sampah yang mencakup keseluruhan wilayah, baik perkotaan maupun pedesaan. Sampah di wilayah pedesaan didominasi oleh sampah organik pasar dan limbah peternakan. Tidak berjalannya sistem pengolahan dan pendistribusian sampah yang baik, menyebabkan penumpukan sampah seperti pada wilayah Dusun Gedangklutuk, Desa Kedungboto, Kabupaten Pasuruan. Kegiatan ini bertujuan untuk memanfaatkan sampah organik dan limbah peternakan sebagai Energi Baru Terbarukan (EBT) ramah lingkungan dengan metode biodigester. Biodigester mampu mengubah sampah organik pasar menjadi biogas yang memiliki kandungan CH4 sekitar 50-75%, CO2 sekitar 25-50%, dan sisanya adalah gas lain yang persentasenya sangat kecil. Gas berasal dari penguraian bahan organik oleh bakteri anaerob dengan suhu optimum sekitar 30-35°C dan pH sekitar 6-8. Biodigester menghasilkan 847,8 liter gas yang tertampung.]]>

<![CDATA[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 > 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.]]>

<![CDATA[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. 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%.]]>

<![CDATA[Pertumbuhan industri dan kebutuhan masyarakat akan memberikan dampak seperti munculnya patogen seperti bakteri Escherichia coli dalam air. Hal ini akan berkontribusi pada penurunan ketersediaan air bersih. Proses desinfeksi diterapkan untuk mengurangi dan membatasi jumlah bakteri Escherichia coli di dalam air. Cuka kayu yang mengandung fenol merupakan salah satu bahan alternatif yang dapat digunakan sebagai disinfektan. Penelitian ini mengkaji penggunaan cuka kayu dalam proses desinfeksi. Proses desinfeksi dievaluasi berdasarkan variasi konsentrasi cuka kayu dan waktu kontak selama proses desinfeksi terhadap analisis jumlah bakteri (MPN) dan analisis residu fenol. Cuka kayu dari limbah serbuk gergaji telah memenuhi kualitas dari segi parameter pH, warna dan transparansi yang mengacu pada The Japan Pyroligneous Liquor Association. Cuka kayu memiliki kandungan fenol sebesar 1.022,456 ppm. Peningkatan konsentrasi fenol dapat meningkatkan daya hambat pertumbuhan Escherichia coli hingga 99,816% sedangkan peningkatan waktu kontak memberikan hasil yang fluktuatif. Proses desinfeksi menggunakan cuka kayu menghasilkan konsentrasi Escherichia coli dan fenol yang berada di atas regulasi jika dibandingkan dengan gas klorin.]]>

<![CDATA[KPSP Setia Kawan has two types of farms, namely conventional dairy farms and organic dairy farms. The research results show that in the milk production process of 1 kg of ECM (Energy Corrected Milk) which was delivered to the farm gate for 1 year, the total carbon footprint of milk produced by dairy farms in 2010 was 1.23 ± 0.04 kg CO2 Eq/kg ECM, 80% comes from on-farm activities. This research will apply the Life Cycle Assessment method with the CMLIA Baseline impact method. This method can be used to carry out impact assessments in the livestock sector so it is common for LCA studies in the dairy sector so it is most suitable for conducting comparative studies. It is hoped that with this research, animal husbandry can find out the effectiveness of implementing organic cattle farming in reducing environmental impacts compared to conventional cattle farming and help promote animal husbandry that prioritizes environmental aspects in the production and supporting processes.]]>

<![CDATA[The coriander cracker industries in Nganjuk City, commonly structured in Small Business scales are still implying conventional equipment in its production. High daily production volumes are resulting the large amounts of liquid waste containing pollutants exceeding Indonesia’s Threshold Value specifically in Chemical Oxygen Demand (COD) at 131.2 mg/L and Total Suspended Solids (TSS) at 203 mg/L. This condition causes serious environmental risks toward improper treatment. The biofilter system is one of wastewater treatment method with a simple and applicable way, applying a biological treatment approach utilizing microorganisms to reduce organic contaminants. This study aims to analyze the influence of media type on the removal efficiency of COD and TSS concentrations in coriander cracker industries’ wastewater using an aerobic biofilter system with the bioball and Kaldness K1 media. Performance testing of the aerobic biofilter demonstrated that the reactor with Kaldness K1 media achieved the highest removal efficiencies, eliminating 85.96% of COD and 95.01% of TSS by day 12. The study confirms that the Kaldnes K1 media's porous surface structure and high specific surface area enhance biofilm growth of microorganisms, thereby optimizing organic matter degradation processes.]]>
