Abstract

ABSTRAKPengolahan padi menghasilkan beras sebagai produk utama dan limbah pertanian seperti sekam dan dedak padi. Industri tahu yang menggunakan kedelai sebagai bahan baku utama menghasilkan sejumlah besar limbah padat dan cair seperti ampas tahu. Jika tidak dikelola dengan baik, kedua limbah ini dapat mencemari lingkungan. Pengelolaan yang tepat dibutuhkan untuk mengurangi dampak negatifnya. Pemanfaatan limbah tersebut sebagai media tumbuh kaya protein bagi maggot lalat BSF. Ampas tahu memiliki kandungan protein tinggi sekitar 20–25 %. Penelitian ini bertujuan untuk mengamati pengaruh berbagai perlakuan media tumbuh terhadap pertumbuhan maggot dan ikan lele Sangkuriang, dengan parameter berupa pengukuran panjang dan berat maggot lalat Black Soldier Fly serta ikan lele. Penelitian ini dilakukan dengan empat perlakuan, yaitu: (I) ampas tahu 20% + dedak padi 80%, (II) ampas tahu 40% + dedak padi 60%, (III) ampas tahu 60% + dedak padi 40%, dan (IV) ampas tahu 80% + dedak padi 20%, masing-masing ditambahkan air 1,5 liter, larutan EM4 20 mL, dan larutan molase 20 mL. Hasil terbaik diperoleh pada perlakuan IV sampel 2. Pada perlakuan ini maggot lalat Black Soldier Fly mencapai pertumbuhan berat mutlak 0,9 gram dan panjang mutlak 8 mm. Pertumbuhan ikan lele Sangkuriang juga paling optimal pada perlakuan IV, dengan rata-rata berat mutlak 106 gram dan panjang mutlak 12,5 cm. Pemanfaatan dedak dan ampas tahu dapat menjadi sumber pakan magot yang menjadi sumber pakan bagi ikan lele sangkuriang. Kata kunci : Ampas Tahu; Dedak Padi; Ikan Lele Sangkuriang; Maggot Lalat BSFABSTRACTThe rice processing process produces rice as the main product but also produces waste in the form of rice husks and rice bran. Similarly, the tofu industry that uses soybeans as the main raw material produces large amounts of waste, including liquid and solid waste such as tofu dregs. If rice bran and tofu pulp are not properly managed, both can pollute the environment. proper management is required to reduce their negative impacts. One applicable solution is using rice bran and tofu dregs as a growing medium for Black Soldier Fly or maggot, feeding optimally on protein-rich media. Tofu pulp has a high protein content of about 20-25%, so it is the right choice as a growth medium. This study aims to observe the effect of various growing media treatments on the growth of maggot and Sangkuriang catfish, with parameters such as measuring the length and weight of BSF fly maggot and catfish. This study was conducted with four different treatments, namely: (I) tofu dregs 20% + rice bran 80%, (II) tofu dregs 40% + rice bran 60%, (III) tofu dregs 60% + rice bran 40%, and (IV) tofu dregs 80% + rice bran 20%, each added 1.5 liters of water, 20 mL EM4 solution, and 20 mL molasses solution. The best results were obtained in the treatment IV of sample 2, where the BSF fly maggot achieved an absolute weight growth of 0,9 grams and an absolute length of 8 mm. The growth of Sangkuriang catfish is also the most optimal in the IV treatment, with an average absolute weight of 106 grams and an absolute length of 12.5 cm. This study conclude that rice bran and tofu dregs can be sources of food for manggot which are suitable for sangkuriang cat fish

Abstract

Waste management operations in Banjarmasin City are still a regional challenge due to the closure of the Basirih landfill. This closure has an impact on waste transportation and disposal activities in Banjarmasin City. The implementation of a new waste paradigm that views waste as a resource can be a solution for waste management in Banjarmasin City. The method used is Tchobanoglous et al (1993). Data on waste generation and composition in Banjarmasin City were obtained from the national waste inventory website. There are 5 elements that can explain the amount of energy content in waste including carbon, hydrogen, oxygen, nitrogen, and sulfur. The analysis results show that the chemical formula of Banjarmasin City waste per day without sulfur content is C49H68O22N (without water) and C49H75O26N (with water). Meanwhile, the chemical formula with sulfur content is C804H1122O365N16S (without water) and C804H1245O427N16S (with water). The energy content using wet weight is 9,808 Btu/lb or 22,813 kJ/kg. While the energy content if the waste uses dry weight is 9,201 Btu/day or 21,402 kJ/kg. This indicates that Banjarmasin City can utilize waste into energy.

Abstract

Carbon dioxide (CO₂) is the main contributor to global warming and climate change. Human activities in residential areas significantly increase CO₂ emissions. Green open spaces such as urban forests play a vital role in absorbing this gas through photosynthesis. This study aims to measure the concentration of CO₂ in the areas of Muhammad Sabki Urban Forest and Grand Kenali Residential Complex, as well as to map its spatial distribution using Geographic Information System (GIS) with the Inverse Distance Weighting (IDW) interpolation method. Data collection was conducted over three days, during three time periods (morning, noon, and afternoon), at four sampling points spaced 65 meters apart. The results show a significant difference in CO₂ concentrations between the two areas, with residential zones showing higher levels than the urban forest. Spatial visualization through digital maps revealed a distribution pattern consistent with the level of human activity and vegetation cover in each area. This research provides valuable insights for emission reduction strategies and sustainable spatial planning. Keywords :    Carbon Dioxide (CO₂), Geographic information system (SIG), IDW, Residental area, Urban ForestABSTRAKEmisi karbon dioksida (CO₂) telah menjadi penyebab utama pemanasan global dan perubahan iklim.

Abstract

Operational activities in hospitals for providing medical services have the potential to produce wastewater containing various contaminants. These substances may pose environmental risks if not treated properly and in accordance with applicable standards. This study aims to evaluate the wastewater treatment system in a Class C Hospital in Banyuwangi by examining the effluent characteristics from the Wastewater Treatment Plant (IPAL) and the technical aspects of its treatment units. The research applied a descriptive quantitative approach through observations of the IPAL to identify wastewater sources and laboratory testing of effluent characteristics. The tested parameters included temperature, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Ammonia (NH₃-N), Total Suspended Solids (TSS), and oil and grease. Secondary data were obtained from regular IPAL test documentation. The effluent characteristics were compared to regulatory limits set in national regulations (Ministry of Environment and Forestry Regulation No. 68 of 2016 on Domestic Wastewater Quality Standards) and East Java Governor Regulation No. 72 of 2013 concerning Wastewater Quality Standards for Industrial and/or Other Business Activities. Most tested characteristics were within acceptable quality standards. However, the COD concentration exceeded the established limit. Observations indicated that most treatment units were in accordance with design criteria, except for the sedimentation unit. Therefore, the Class C Hospital in Banyuwangi needs to follow up and optimize the performance of its IPAL system, particularly in the sedimentation unit.Keywords :    Wastewater, evaluation; hospital, wastewater treatment; quality standard ABSTRAKAktivitas operasional rumah sakit dalam memberikan layanan medis berpotensi menghasilkan air limbah yang mengandung berbagai kontaminan.

Abstract

The Jambi Province has smallholder plantations established on peatlands, one of which is the local Betara variety of areca palm (pinang), known for its adaptability to high peat water table (TMAT) conditions. However, drainage remains necessary to prevent waterlogging. Peat decomposition releases carbon emissions, including dissolved organic carbon (DOC) into drainage water. The IPCC emphasizes the need for scientific data on carbon loss through DOC from tropical peatlands. This study was conducted in a Betara areca palm plantation located in Catur Rahayu Village, Dendang Subdistrict, Jambi, aiming to obtain quantitative data on DOC concentration in peatland drainage. TMAT observations and water sampling were carried out in a 100x100 m plot during the rainy season, coinciding with flooding in nearby areas. The results showed that the lowest TMAT reached -50 cm, consistently recorded at 20 observation points, indicating peat vulnerability even during the rainy season. No correlation was found between peat depth and TMAT. Groundwater from the peat flowed into a nearby tertiary canal connected to a secondary canal. The average DOC concentration at TMAT monitoring points was 3.321 mg/L, and in the tertiary canal, it was 3.309 mg/L. Keywords: Carbon; DOC; Drainage; IPCC; TMAT.ABSTRAKProvinsi Jambi memiliki perkebunan rakyat di lahan gambut, salah satunya adalah kebun pinang varietas lokal Betara yang adaptif terhadap kondisi tinggi muka air tanah (TMAT) gambut.

Abstract

Noise is one of the important risk factors in the workplace that is often overlooked, particularly in small-scale furniture enterprises that have limitations in controlling the work environment. High noise exposure has the potential to cause hearing disorders as well as non-audiological complaints that impact worker productivity. This study aimed to analyze noise levels using a multi-level approach at the sound source, workers, supporting areas, and surrounding environment, and to examine their relevance to worker characteristics. The study was conducted in furniture enterprises in Tanjungpinang City with a quantitative descriptive design, using direct noise measurements in accordance with the Ministry of Manpower Regulation No. 5 of 2018 and a worker characteristics questionnaire. The findings showed that 78% of workers were exposed to noise exceeding the Threshold Limit Value (TLV), with the majority being in the productive age group (59%) and having more than two years of work experience (69%). A total of 31% of workers reported hearing complaints and 63% experienced non-audiological symptoms, while more than half of the workers (53%) did not use personal protective equipment (PPE). Multi-level analysis revealed that noise originated not only from machines but was also influenced by workspace layout, worker behavior, and the lack of environmental protection systems. In conclusion, noise control requires a comprehensive strategy through workspace layout adjustments, engineering controls on machines, increased compliance with PPE use, and protection of the surrounding environment. The contribution of this study emphasizes the urgency of a multi-level approach in protecting worker health, improving productivity, and supporting the sustainability of furniture enterprises.
