Abstract

Biodiesel adalah sumber bahan bakar alternatif yang dapat dihasilkan dari minyak jelantah melalui proses transesterifikasi merupakan salah satu potensi untuk digunakan sebagai bahan dasar produksi biodiesel. Penelitian ini bertujuan untuk mengetahui pengaruh variasi suhu dan waktu katalis zeolite terhadap biodiesel yang dihasilkan. Sintesis biodiesel diawali dengan pembuatan katalis Zeolit melalui proses kalsinasi Zeolit pada suhu 800 oC, 900 oC, 950 oC kemudian dilakukan perendaman dengan larutan KOH 1 : 1 dalam 100 ml pelarut air. Kemudian dilanjutkan proses pengeringan selama ± 1 jam pada suhu 110 oC dan kalsinasi pada suhu 800 oC, 900 oC, dan 950 oC. Perbandingan volume minyak dan methanol sebesar 1:19 dengan katalis 2% dari berat minyak. Hasil analisa XRD katalis zeolite dengan kristalinitas 1500 cps, untuk standar kualitas biodiesel parameter yang diuji yaitu densitas 0,86gr/cm2 ,viskositas 1,45mm2/s dan %yield 72,5%.

Abstract

Improving the quality of life and welfare through industrial development in various sectors often results in negative impacts such as production waste. One type of waste produced from coal combustion is fly ash and bottom ash, both of which were categorized as hazardous waste (B3) according to government regulations before 2021. With regulatory changes in 2021, this waste can be utilized more flexibly after obtaining Environmental Approval. This study examines the use of bottom ash as an adsorbent to reduce heavy metals in industrial wastewater. Bottom ash from PT PUSRI Palembang was processed into silica gel using the sol-gel method and NaOH activation, with the liquid waste used coming from the liquid waste of the beverage industry in Banyuasin. The results showed that silica gel successfully made from bottom ash has an adsorption capacity following the Langmuir model, with a value of 1.743 mg/g and an adsorption efficiency of 73.69%. The optimal NaOH concentration was found at a 3 M ratio with an average efficiency of 70.84%.
