Saat ini pengolahan sampah organik dapat dilakukan dengan berbagai cara, salah satunya dengan bantuan lalat tentara hitam (larva black soldier fly-BSF). BSF merupakan jenis serangga yang sangat tepat untuk melakukan penguraian sampah organik. Penelitian ini bertujuan untuk mengolah sampah organik rumah tangga dengan bantuan BSF yang dapat menghasilkan produk samping berupa pupuk organik cair yang berasal dari leachate yang dihasilkan selama pengolahan. Dalam penelitian ini, sampel dibagi kedalam 10 variasi sampel uji dan dibandingkan dengan Keputusan Menteri Pertanian Republik Indonesia No. 261 Tahun 2019 tentang Pupuk Organik, Pupuk Hayati dan Pembenahan Tanah. Hasil uji laboratorium pupuk organik cair, didapatkan bahwa hanya parameter logam berat, pH, dan Salmonella sp. yang telah memenuhi baku mutu. Perlakuan aerasi mengurangi kandungan E.coli dan Salmonella Sp. Perlu dilakukan penelitian lebih lanjut dengan pengomposan dan pemanenan sampel leachate pada sampel pupuk cair yang lebih lama agar hasil yang didapatkan dapat memenuhi baku mutu yang digunakan.
The Jakarta regulation for waste cooking oil (WCO) shows the desired WCO to Biodiesel supply chain through the DKI Jakarta Governor Regulation Number 167 the Year 2016. Still, the implementation of said regulation proved inefficient. The study aims to analyze the risks in the supply chain because the WCO to Biodiesel supply chain is vulnerable to different risks than the typical supply chain and the green supply chain. The method used in this research is the group analytical hierarchy process (G-AHP) approach to create a consensus model between actors of the supply chain. Deep interviews were conducted with six experts to identify the risks and the normal scale was used to quantify their preference. Then, the PriEst software assisted the risk weight calculation, AHP matrix validation, and consensus modelling. The findings show the supply chain is vulnerable to 23 risks, categorized into six risk categories. The three risks that cause the most uncertainties in the supply chain are supply chain design risk, key supplier risk, and financial source risk. Technology risks and asset failure risks are the least concern because most WCO conversion is not done in Indonesia. These findings would be useful for the government to focus its effort on the most critical risks.
The 35 Community Health Centers in Depok City have limited resources and other duties besides serving patients. This limitation makes the Community Health Centers difficult to comply with the regulation of Regulation of Environmental and Forestry Ministry Number 56 Year 2015 on “Procedures and Technical Requirement of Hazardous Waste Management from Healthcare Facilities”, therefore there is need for adjustments and appropriate decision making in hazardous waste management, which can be done using Analytical Hierarchy Process (AHP) methods. AHP methods use 3 principles, which is hierarchy making, priority determination, and consistency ratio. The objective of this research is to choose the most optimal alternative for hazardous medical waste management, starting from reducing, sorting, storing, transporting, treatment, until burial. After conducting pair comparison from all respondent, the data processing is done using Expert Choice 11 software. This software helps in choosing alternatives via many criteria by inputting the comparison value from each respondent and display the priority value from each alternatives. The chosen alternative is as follows: reducing wasteby a good housekeeping, sorting phase with two containers or plastic bags, storing phase with freezer as described in Regulation of Environmental and Forestry Ministry Number 56 Year 2015, transportation phase using closed truck, off-site treatment, and burialusing secure landfill.
Used cooking oil are oils that have been used for cooking in restaurants, hotels, food industries, and households. They are dangerous waste when inappropriately disposed since it can interrupt the sewer system or be illegally reprocessed. To combat the issue, the government of Jakarta designed the UCO to Biodiesel supply chain in the Governor’s Regulation number 167 of 2016. However, it has yet to manage households despite potentially producing 210.465,31 litres of UCO per day. The goal of this community service is to create a collection system and to increase awareness of the dangers and potential of UCO in Bassura City Apartment, located in East Jakarta, which did not have UCO collection system. The collection system considers sustainability in terms of not only the environment but also social and economic. The community service is split into five steps: creating local partnerships, supply chain planning, awareness raising by socialization, monitoring and evaluation. Local partnership was created between the local mosque Al-Falah as local UCO collector, BeliJelantah the medium sized UCO collector, and Universitas Bakrie. UCO collected by Al-Falah is bought by BeliJelantah at a rate of Rp4,000.00 /litre. BeliJelantah provides basic equipment such as jerrycans and sieve. Socialization was partially done regularly before sermon and online due to Covid-19 restrictions. Since the implementation of the collection system, Al-Falah mosque has collected 33 Litres which was converted into Rp134,000.00. Sustainability of the collection of used cooking oil will be carried out by residents and the DKM Masjid in direct coordination with BeliJelantah by taking a minimum of 2 jerrycans with a volume of 18 litre or the equivalent of 36 litre. This system can be scaled up by increasing partnerships with more local groups and local management.
<strong>Aim:</strong> The purpose of this study is to determine the effect of noise on work fatigue at Central Processing Plant (CPP) Gundih Completed. Noise is one of the causes of fatigue in the oil and gas industry. <strong>Methodology and Result</strong>: Noise is measured using a Sound Level Meter at 45 sampling points spread across two gas processing zones at CCP Gundih in Cepu is Utility zone and Main Process zone. The noise distribution pattern based on noise level in gas processing field of CPP Gundih made using Surfer 11 software. Measurement of fatigue using the Fatigue Measure Measurement Questionnaire and Subjective Self Rating Test questionnaire from Industrial Fatigue Research Comitte Japan. The results of this study prove that the Utility Zone at the sampling point 35 to 45 has a noise level of 74,229 dBa - 106,285 dBa, point 45 has passed the Noise Decree of Kepmenaker No. 51 of 1999, but overall the sampling point in the Utility zone has passed through Kepmenlh no. 48 in 1996. In the Main Process zone at sampling points 6 to 17 and 30 have passed the standard noise level Kepmenaker no. 51 of 1999 with a noise level of 85.967 dBa to 87.155 dBa and 85.146 dBa. Overall there are 4 sampling points that do not pass the standard noise level of Kepmenlh no. 48 of 1996 and Kepmenaker no. 51,1999 points 25, 26,31 and 33. <strong>Conclusion, significance and impact study: </strong>Noise affects fatigue based on several factors, including noise factor 39%, 32.1% weakening activity factor and physical fatigue factor 28.2%.
