Pencemaran udara akibat emisi bahan bakar fosil dan keterbatasan cadangannya mendorong pengembangan energi alternatif seperti biopelet berbasis biomassa, salah satunya dari tempurung kelapa yang melimpah di Indonesia namun masih perlu ditingkatkan kualitasnya. Penelitian ini menggunakan metode oil coating microparticle berbasis minyak jelantah untuk meningkatkan karakteristik biopelet non-karbonisasi, termasuk densitas, efisiensi pembakaran, serta penurunan kadar air dan abu. Penelitian dilaksanakan di Laboratorium TSTET Universitas Jenderal Soedirman pada Januari-Maret 2025 dengan bahan tempurung kelapa, minyak jelantah, tepung kanji, dan air, serta menggunakan Rancangan Acak Lengkap (RAL) dengan empat taraf perlakuan waktu pencelupan: T0, T1, T2, dan T3. Parameter yang diamati meliputi kadar air, abu, volatile matter, laju pembakaran, densitas, shatter index, dan nilai kalor, dianalisis menggunakan ANOVA dan DMRT. Hasil menunjukkan bahwa perlakuan oil coating mampu meningkatkan kualitas biopelet secara signifikan, dengan perlakuan RT3 memberikan hasil terbaik pada sebagian besar parameter utama, mengindikasikan bahwa metode ini efektif sebagai pendekatan selektif untuk meningkatkan kualitas biopelet berbasis tempurung kelapa.

Air pollution caused by fossil fuel emissions and their limited reserves has driven the development of environmentally friendly and sustainable alternative energy sources, such as biomass-based bio-pellets. Coconut shell, which is abundant in Indonesia, serves as a potential raw material but requires quality improvement to compete with other fuels. This study applied an oil coating microparticle method using used cooking oil to enhance the characteristics of non-carbonized bio-pellets, including density, combustion efficiency, and the reduction of moisture and ash content. The research was conducted at the Thermal System and Renewable Energy Engineering Laboratory (TSTET), Jenderal Soedirman University, from January to March 2025, using coconut shells, used cooking oil, starch, and water, and employed a Completely Randomized Design (CRD) with four treatment levels of oil immersion time: T0, T1, T2, and T3. Observed parameters included moisture content, ash content, volatile matter, combustion rate, density, shatter index, and calorific value, analyzed using ANOVA and further tested with Duncan's Multiple Range Test (DMRT). The results showed that the oil coating treatment significantly improved the bio-pellet quality, with the RT3 treatment yielding the best results across most parameters, indicating that this method is effective as a selective approach for enhancing the quality of coconut shell-based biopellets
