Abstract

Kota Sungai Penuh tidak memiliki lokasi Tempat Pengelolaan Akhir (TPA) sampah. Pemerintah menyewa lahan warga untuk dijadikan Tempat Penampungan Sementara (TPS) di Desa Renah Padang Tinggi dengan luas 1,6 Ha. Kondisi ini membutuhkan upaya pengurangan sampah secara optimal dari sumbernya. Salah satu sumber sampah terbesar adalah sampah rumah tangga yang bisa dikelola di bank sampah dan TPS 3R. Berdasarkan data Dinas Lingkungan Hidup (DLH) Kota Sungai Penuh tahun 2024, terdapat 1 unit bank sampah dan 16 unit TPS 3R yang berpotensi mengurangi sampah menuju TPA jika dikelola dengan baik. Tujuan penelitian ini adalah untuk menyusun rencana strategi peningkatan pengelolaan bank sampah dan TPS 3R di Kota Sungai Penuh. Pendekatan yang dilakukan untuk menentukan strategi yaitu Strength Weakness Opportunity Threat (SWOT) dan Analytical Hierarchy Process (AHP). Analisis SWOT dilakukan dengan menghitung nilai bobot dan rating dari hasil penetapan faktor internal dan eksternal yang menghasilkan strategi diversifikasi yaitu memaksimalkan kekuatan untuk mengatasi atau mencegah ancaman. Analisis AHP menghasilkan strategi prioritas pengelolaan sampah pada bank sampah dan TPS 3R yaitu yaitu memaksimalkan pengoperasian TPS 3R dan Bank Sampah yang terintegrasi dengan BUMDes dengan nilai bobot 0,28.

Abstract

The increasing world population, rapid industrialization, urbanization, and economic growth have led to a continuous increase in the consumption of fossil fuels to meet the ever-increasing demand for energy. Continuous emissions from burning fossil fuels will create a need to find appropriate and sustainable substitutes for fossil fuels. Biodiesel is the right alternative solution for diesel engines because it is renewable, non-toxic, and environmentally friendly. Waste cooking oil (WCO) from the food, non-food, restaurant, and household sectors is produced on a large scale in every country and can contribute to environmental pollution if proper disposal systems are not applied. Instead of throwing it landfills Environmental pollution can be minimized by recycling WCO. This study evaluates the potential of using WCO to produce biodiesel using zeolite synthesized from fly ash as a heterogeneous alkali catalyst through a transesterification reaction. The reactor in this study used a 1,000 ml three-necked boiling flask equipped with a condenser, cooling tank, and pump. Stirring and heating during the process of biodiesel production using a magnetic stirrer and a hot plate. The thermometer is used to measure the reaction temperature. Optimization of biodiesel production from zeolite catalyst synthesized from fly ash based on variations in the ratio of methanol: oil (8:1; 10:1; 12:1; and 14:1), catalyst weight (1, 2, 3, and 4% weight), and temperature (45 oC, 55 oC, and 65oC). Zeolite from fly ash produces biodiesel with a yield of 91.67% with optimum operating conditions reaction time of 60 minutes, methanol oil ratio of 8:1, operating temperature 55oC, and the amount of catalyst 1% by weight. This experiment confirms the possibility of utilizing fly ash waste for the application of catalysts in biodiesel production.

Abstract

Burning coal in a Coal-Fired Power Plant produces by-products like fly ash and bottom ash. Zeolite synthesized from the ash in Teluk Sirih Coal-Fired Power Plant was applied as a catalyst in the biodiesel transesterification reaction. Zeolite synthesis used the hydrothermal method with acid pretreatment. The operating conditions for fly ash zeolite are a 2.4-molar ratio SiO2/Al2O3 and a crystallization time of 6 hours. The bottom ash zeolite used a 2.0-molar ratio SiO2/Al2O3 and a crystallization time of 8 hours. The performance test of the synthesized catalyst was carried out in the transesterification reaction using waste cooking oil as a raw material with a free fatty acid content of 0.7%. The synthesized catalyst was characterized using x-ray diffraction, scanning electron microscope, and Bruneuer-emmet-teller. The biodiesel with the highest yield was analyzed based on SNI 7182: 2015. The synthesis results of the catalyst produced type A zeolite, shown by the typical X-ray diffraction pattern and supported by the morphological test results using a cube-shaped. The surface area of zeolite fly ash and bottom ash is 12.87 m2/g and 5.13 m2/g. The test showed fly ash zeolite had the highest biodiesel yield of 89.66%. Based on the characterization using SNI 7182: 2015, the color and free glycerol met the standards, while density 40 C, kinematic viscosity 40 C, acid number, total glycerol, methyl ester content, and water content did not meet the standards.

Abstract

One of the main challenges in agricultural practices is the heavy reliance on chemical fertilizers without being balanced by the use of organic fertilizers. This study aims to analyze the maturity, quality, and quantity of compost produced from a mixture of cow dung, garden waste, and market waste using the Takakura Layered Method with EM4 and Local Microorganisms (LMOs) as activators. The LMOs used included LMO A (tuna fish waste, sugarcane bagasse, and pineapple peel) and LMO B (tuna fish waste, banana peel, and vegetable scraps). Composting was conducted in duplicate with seven treatment variations: (A) cow dung with EM4, (B) cow dung with LMO A, (C) cow dung with LMO B, (D) cow dung mixed with garden waste and LMO A, (E) cow dung mixed with garden waste and LMO B, (F) cow dung mixed with garden and market waste with LMO A, and (G) cow dung mixed with garden and market waste with LMO B. The results showed that all treatments met the composting standards. All variations complied with the Indonesian National Standard (SNI 19-7030-2004) in both maturity parameters (pH, temperature, color, texture, odor, and composting duration) and quality parameters (moisture content, C-organic, nitrogen, C/N ratio, phosphorus, and potassium). The compost quantity was reduced by 27–58%. The best result was observed in variation (D1), which consisted of cow dung, garden waste, and LMO A, achieving a score of 39 with a composting time of only 6 days.

Abstract

Pariaman City's waste generation in 2022 is 38.26 tons/day. Waste management in Pariaman City is still not optimal, resulting in waste piling up in TPA South Tungkal. The waste reduction value at the research location after processing with BSF larvae can reduce 0.005 tons/day or 0.02% of the total waste generation in Pariaman City. The environmental impacts in waste management studied are Global Warming Potential (GWP), Acidification Potential (AP), and Eutrophication Potential (EP). Reducing the environmental impact of processing organic waste has been carried out, the smallest impact reduction results were obtained, namely in scenario 1, namely processing organic waste with BSF larvae in waste banks and TPS 3R. The results obtained were the impact characterization value from comparing several impact categories. GWP value 32,060,838.136 103 kg CO2-eq, AP 0.00246 x103 SO2-eq, and EP 0.00134 x103 kg PO4-3. So it can be concluded that scenario 1 has a smaller GWP, AP, and EP impact on the environment compared to scenario 0 and is used as the best alternative scenario for waste management in Pariaman City
