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.

Abstract

Dalam upaya membatasi kenaikan suhu global 1,5 derajat Celsius pada tahun 2050, peserta COP26 pada November 2021 sepakat untuk menurunkan akumulasi gas metana. Gas metana merupakan salah satu gas rumah kaca yang memberikan dampak yang besar bagi peningkatan pemanasan global. Potensi reduksi gas metana di Indonesia terdapat pada teknologi menangkap gas metana (methane capture) dari limbah cair yang bersumber dari pabrik pengolahan kelapa sawit. Penelitian ini bertujuan untuk mengetahui seberapa besar reduksi gas metana yang bisa ditangkap oleh teknologi methane capture serta mengetahui nilai finansial pemanfaatan gas metana baik dari sisi finansial perusahaan maupun bagi lingkungan hidup. Penelitian ini menggunakan metode mixed method explanatory. Dari aspek lingkungan, pemanfaatan methane capture mampu menangkap gas metana sebanyak 17.517,79 t-CO2e (93,81%) pada kolam anaerobik. Valuasi ekonomi dari gas metana diperoleh dalam NPV adalah sebesar Rp. 31.219.230.000 selama 20 tahun umur ekonomisnya yang dihitung dari nilai ISCC Insentif. Nilai ini menjadi semakin besar, yakni Rp. 63.808.660.000 apabila gas metana tersebut dimanfaatkan untuk membangkit tenaga listrik. Namun, perusahaan akan merugi apabila tidak mendapatkan ISCC insentif dari pasar Eropa dan Amerika Serikat, yakni NPV menjadi sebesar Rp. -6.444.990.000. Kerugian ini lebih besar dibandingkan dengan perusahaan yang menggunakan pembangkit listrik diesel yang berbahan bakar fosil, yakni dengan NPV Rp. -4.857.560.000. Ada selisih sebesar Rp. -1.587.430.000 yang menjadi disinsentif bagi perusahaan kelapa sawit dalam menggunakan teknologi methane capture. Apabila diterapkan pajak karbon untuk pabrik kelapa sawit yang tidak menggunakan teknologi methane capture, berdasarkan UU nomor 7 tahun 2021, maka pembebanan biaya yang lebih besar sehingga nilai NPV Rp. -15.446.640.000 dibanding sebelum diterapkannya pajak karbon.

Abstract

The issue of organic waste in Padang City is increasing due to the community's high activity level, which predominantly generates food waste. Currently, food waste accounts for 63% of the total waste in Padang City. The Black Soldier Fly (BSF) maggot is an effective agent for processing organic waste, requiring simple technology that is cost-efficient and easy to implement. BSF maggots also produce biomass with a high protein content that can be utilized as animal feed. The methods used in this study include socialization, education, direct field practice, and evaluation. The results demonstrated an increase in community understanding and interest in BSF maggot cultivation as a means to reduce organic waste. Participants also learned about the TOSS (Solid Waste Processing Technology at the Source) method for managing leaf and twig waste. This activity was expected to serve as a waste management model that reduces waste volume and creates opportunities within the circular economy, where organic waste is converted into valuable resources.
