Abstract

Dalam proses pemotongan hewan, selain menghasilkan daging, rumah potong hewan kota Pekanbaru juga menghasilkan limbah, seperti darah, rumen dan kotoran. Berdasarkan wawancara dan observasi langsung, limbah pemotongan hewan hanya sampai ke tempat penampungan akhir tanpa adanya proses lebih lanjut, jika dibiarkan seperti itu maka akan berdampak ke lingkungan dan kesehatan. Penelitian ini bertujuan menghitung nilai potensi biogas dari limbah rumen sapi yang merupakan limbah yang paling berpotensi, juga menghitung potensi energi listrik. Pada penelitian ini juga melakukan analisis biaya seperti biaya investasi dan pay back period. Metode penelitian menggunakan fermentasi anaerob untuk potensi biogas, dengan bantuan aplikasi simulasi Superpro Designer. Dari 1.000 kg rumen sapi menghasilkan potensi biogas sebesar 124.949,2351 L/hari dengan kadar gas metan sebesar 78,65%. Potensi energi listrik yang dihasilkan sebesar 180,4 kWh dalam sehari. Dalam analisis biaya  Total investasi dalam pemanfaatan limbah rumen sapi sebesar Rp. 220.049.150. Dan pengembalian modal tercapai dalam waktu 2,4 tahun

Abstract

Sampah merupakan masalah terbesar untuk kota-kota besar di Indonesia, khususnya sampah plastik yang sulit untuk dimanfaatkan kembali. RSD Madani merupakan salah satu penyumbang limbah medis berbahan plastik di kota Pekanbaru, pemanfaatan limbah plastik dengan cara Pirolisis, proses ini dapat mengkonversi limbah plastik menjadi bahan bakar minyak (BBM). Penelitian ini bertujuan untuk menghitung potensi minyak pirolsis dari limbah medis berbahan polyprophylene dan potensi energi listrik yang dihasilkan oleh minyak pirolisis. Penelitian ini menggunakan metode Pirolisis dibantu dengan simulasi SuperPro Designer sehingga diperoleh volumetric flow dari minyak pirolisis. Dari hasil simulasi diperoleh minyak pirolisis dengan jumlah volumetric flow sebesar 3523,70 L dengan kandungan minyak pirolisis sebesar 97,8314%. Energi listrik yang dapat dihasilkan dari minyak pirolisis sebesar 132.575,02 kWh dalam satu tahun sehingga perhari dapat menghasilkan energi listrik sebanyak 363,21 kWh. Potensi daya yang dihasilkan oleh minyak pirolisis adalah 15,13375 kW dalam satu hari.

Abstract

North Bagan Sinembah village in Riau province contributes a land area of ​​7.376,4443 ha which produces frond biomass 6,3 tons of oil palm fronds per year, North Bagan Sinembah Village so far has not had access to PLN electricity and only uses a generator with a running time of 6 hours per day. This research aims to find the electricity needs of North Bagan Sinembah village with a homogeneous sample, the sampling method used is simple random sampling. This research too test the potential of palm frond bioethanol using the fermentation method using the SuperPro Designer application, calculate potential energy and electrical power with method from a variety of mixed fuels E10%, E30%, E50%, E100%. The electricity needs of North Bagan Sinembah Village are 867,62 kWh with volumetric flow potential of 15,72 L/ha/day, 1.641,66 L/ha/month and 18.053,72 L/ha/year. By using a variety of fuel mixtures E10 produce 172,68 kWh/day, 5.261,88 kWh/month, 57.866,3 kWh/year. E30 produce 161,77 kWh/day, 4.855,16 kWh/month, 53.392,6 kWh/year. E50 produce 1.632,9 kWh/day, 50.400,66 kWh/month, 538.747,9 kWh/year and E100 produces electrical power of 1,257.30 kWh/day, 38,808.48 kWh/month, 414,835.88 kWh/year. The potential electrical power for the fuel mixture is E10 4,144.32 Watts/day, 126,285.12 Watts/month, 1,388,791.2 Watts/year. E30 produces 3,882.48 Watts/day, 116,523.84 Watts/month, 1,281,422.4 Watts /year, E50 39,189.6 Watts/day, 1,209,615.84 Watts/month, 12,929,949.6 Watts/year and E100 produces 30,175.2 Watts/day, 931,403.52 Watts/month, 9,956,061.12 Watts/year. It can be concluded that with variations in the fuel mixture of dexlite and ethanol at each percent of the mixture, it has a large potential for E50 (50% Dexlite and 50% ethanol) per year of 12,929,949.6 watts, due to harvesting palm fronds twice a month, the production bioethanol is carried out every month with a potential electrical power of 1,209,615.84 watts/month.

Abstract

Waste in Indonesia reaches 65.2 million tons/year, dominated by organic and inorganic waste. Around 36% of the total waste has not been managed properly, including 4K1P waste (paper, wood, cloth, rubber, and plastic), which is flammable and can be made into RDF briquettes using the pyrolysis method and paraffin adhesive which will used three variations of raw materials, namely from organic, inorganic and mixed waste. The quality of the three briquettes was compared based on calorific value, ash content, water content, and PLTU fuel requirements if used as fuel for a 7.5 MW capacity PLTU. The weight of the initial raw material for briquettes is 2 kg which produces 875 grams of paper carbon charcoal, 648 grams of wood, 1.09 kg of plastic, 856 grams of cloth, and 1.16 kg of rubber, resulting in 10 pieces of organic, inorganic and mixed briquettes each. The test results show that inorganic briquettes have the best quality with a calorific value of 8,075.92 cal/g, water content of 1.75%, and ash content of 10.84%, where the calorific value and water content meet SNI-01-6235-2000. The minimum fuel requirement for a PLTU using RDF briquettes is inorganic briquettes, namely 3.05 tonnes/hour with an annual requirement of 26,205.6 tonnes/year. It can be concluded that inorganic briquettes have the best quality and require the least amount of fuel to be used in PLTU.
