Abstract

Leachate, a byproduct of water entering landfills, contains high amounts of organics, acids, metals, and dissolved salts, posing environmental risks. Due to leachate can be hazardous and there are few remediation alternatives, researchers are exploring leachate reduction methods using decomposing organisms like Black Soldier Fly (BSF) larvae. This research investigates BSF larvae's ability to decompose leachate, determines the quality of the final residue and analyzes the growth of the larvae. BSF larvae were grown for 12 days on a mixture of substrate and leachate. The variations used are the solvent content of the leachate solution (75%, 50%, 25%, and 0% solvent) and the type of substrate (bran, tofu dregs, or a mixture of tofu bran-dregs). Using leachate in raising BSF larvae effectively degrades leachate and creates standardized organic fertilizer. The substrate type and solvent content of the leachate solution affect media reduction. As the solvent gets smaller or the leachate concentration increases, the medium shrinks more. The highest media shrinkage of 58.83% is achieved by combining bran and tofu dregs with 0% leachate solution solvent concentration.

Abstract

Altoro restaurant and bar activities will produce domestic and kitchen wastewater which is estimated to have pollutant levels of 680 mg/l BOD, 1000 mg/l COD, 100 mg/l TSS, 200 mg/l oil and grease and a pH of 6. This figure does not meet the water quality standards according to PERMEN LHK Number 68 of 2016, so water treatment needs to be carried out before being discharged into water bodies. Characteristics that do not meet water quality standards will become a reference for planning waste water treatment. The technologies planned for use in wastewater treatment are Grease Traps and aerobic-anaerobic Biofilters. The efficiency of the grease trap is known to reduce BOD, COD, oil and grease respectively 77%, 77% and 95%. Aerobic-anaerobic Biofilter efficiency is known to reduce BOD, COD, TSS, Oil and Fat respectively 99%, 93%, 99% and 85%. Eluent water from the aerobic-anaerobic Biofilter meets quality standards and will be stored in a storage tank before being channeled to the sewer.

Abstract

At present, restaurants and entertainment venues are places that are growing very rapidly in big cities. From business/production activities, Allegra produces B3 waste. B3 waste contains materials that can pollute the environment and endanger humans and other living things. Therefore, it is necessary to plan the container and layout of the B3 Waste Temporary Storage. The data needed in this study are the types and characteristics of B3 waste, B3 waste generation, packaging planning as a B3 waste container and calculations that produce a TPS area that has sufficient capacity to temporarily accommodate B3 waste produced by Allegra. Based on the research that has been done, the results show that each waste is placed in a 200lt metal drum container, trash bag, container, and iron rack. A metal drum is placed above the container, a trash bag is placed on a pallet to avoid spillage on the floor. For waste of used rags and used accumulators/batteries, insulation is provided because they are flammable. The TPS for B3 waste is equipped with a B3 waste symbol, a 3 Kg fire extinguisher, air vents, lighting and a sink to meet the technical requirements for storing B3 waste.

Abstract

Environmental issues related to waste management and the need for sustainable agriculture have driven the search for eco-friendly alternatives. This study explores the utilization of eco-enzyme as a coagulant and organic fertilizer. Eco-enzyme, produced through fruit peel fermentation, was tested for its effectiveness in particle sedimentation in wastewater and enhancing soil fertility. The research employed an experimental approach, using jar test for coagulation and applying eco-enzyme as a liquid fertilizer on plants. Results indicate that eco-enzyme is less effective as a coagulant due to an increase in Total Suspended Solids (TSS) and water turbidity. However, eco-enzyme made from dragon fruit peel (U3) met the liquid organic fertilizer standards with appropriate C, N, P, and K levels, significantly improving soil fertility and plant growth. In conclusion, eco-enzyme has potential as an eco-friendly organic fertilizer but is less effective in coagulation functions.

Abstract

Each year, universities enroll new students, which increases the use of motorized vehicles. An increase in the number of motorized vehicle users can cause noise impacts around the learning area, which can disrupt the learning process. The data needed is vehicle volume, vehicle speed, and road specifications. The collected data are then processed using the CoRTN model to obtain the noise level. The research was conducted at UPN "Veteran" East Java with 4 locations in the morning, afternoon and evening. Based on the results obtained, the peak of vehicle volume occurred in the afternoon with 14,763 vehicles at point 1, the highest vehicle speed occurred at 12.30 WIB at points 1 and 2 with 15 Km/hour, the highest noise occurred in the afternoon at point 2, namely 84 dB(A), and the noise with the lowest intensity occurred in the afternoon at point 4 with 62 dB(A). The noise level prediction results indicate that the noise exceeds the quality standard. Noise is affected by vehicle volume and vehicle speed. However, the vehicle volume affects the vehicle speed. The larger roads but low volume, vehicle speed will increase. However, if the volume is high, the vehicle speed will decrease. The statistics show that the model is good enough to explain the influence of vehicle volume and vehicle speed on noise.

Abstract

Proses pewarnaan kain batik menyebabkan tingginya kadar senyawa organik pada air limbah batik. Senyawa organik yang tinggi dapat ditunjukkan oleh nilai COD. Baku mutu nilai COD air limbah industri batik pada Peraturan Gubernur Jawa Timur Nomor 72 Tahun 2013 tentang baku mutu air limbah bagi industri tekstil sebesar 150 mg/l dan rentang pH yang diperbolehkan adalah 6-9. Sehingga diperlukan adanya pengolahan air limbah batik sebelum dibuang ke badan air. Salah satu pengolahan biologis yang dapat digunakan adalah lumpur aktif. Berdasarkan latar belakang di atas, tujuan dari penelitian ini yaitu untuk mengetahui penurunan konsentrasi COD pada proses aklimatisasi pengolahan air limbah industri batik Jetis. Penelitian ini dilakukan dengan sistem batch dengan variasi jenis bakteri, konsentrasi substrat dan pH yang berbeda beda. Parameter yang dianalisis adalah COD. Dari penelitian ini didapatkan hasil efisiensi penyisihan tertinggi terjadi pada konsentrasi substrat 100% pH 7. Hal itu disebabkan oleh adanya pengaruh nilai pH optimum untuk pertumbuhan bakteri dan jumlah susbtrat.
