Abstract

Biodiesel memiliki potensi besar sebagai energi terbarukan untuk mengurangi ketergantungan Indonesia pada bahan bakar fosil sekaligus menekan emisi gas rumah kaca. Penelitian ini bertujuan mengevaluasi potensi biodiesel di Indonesia melalui kajian literatur terhadap kebijakan, kendala, serta strategi pengembangannya. Metode yang digunakan adalah literature review dengan menelaah 23 artikel terbitan 2015–2025 yang relevan dengan topik biodiesel. Hasil kajian menunjukkan bahwa meskipun kebijakan mandatori B-2,5 hingga B-35 berhasil meningkatkan produksi dan konsumsi biodiesel secara signifikan, implementasinya masih menghadapi empat kendala utama, yaitu ketergantungan pada kelapa sawit sebagai bahan baku, keterbatasan infrastruktur distribusi, hambatan pendanaan akibat biaya produksi tinggi, serta kompleksitas teknologi konversi. Strategi yang diusulkan meliputi diversifikasi bahan baku melalui minyak jelantah, limbah pertanian, dan mikroalga; pengembangan teknologi katalis heterogen dan metode intensifikasi proses (microwave, ultrasonik); optimalisasi subsidi dan instrumen fiskal; pembangunan infrastruktur distribusi di luar Jawa; serta kolaborasi internasional dalam transfer teknologi dan pasar ekspor. Kajian ini menegaskan bahwa dengan integrasi strategi tersebut, biodiesel berpotensi menjadi pilar utama transisi energi berkelanjutan di Indonesia. Kata kunci: Kajian Literatur, Kebijakan Biodiesel di Indonesia, Solusi Energi Keberlanjutan.

Abstract

This study aims to synthesize, characterize, and evaluate the photocatalytic activity of a montmorillonite–ZnO (MMT/ZnO) composite for the degradation of methylene blue (MB) under ultraviolet (UV) and dark (non-UV) conditions. The composite was prepared by mixing synthetic montmorillonite derived from Indonesian soil with ZnO in ethanol, followed by calcination at 400 °C for 2 hours, and subsequently characterized using X-ray fluorescence (XRF). The degradation tests were performed using various composite masses (0.5–2.5 g) and compared with single ZnO and montmorillonite materials through visible spectrophotometry analysis. The results revealed that under UV irradiation, MMT/ZnO achieved the highest degradation efficiency of 98.37%, while under non-UV conditions, MB removal remained high at 88.39%, primarily driven by adsorption. These findings confirm a synergistic effect between the adsorption capacity of montmorillonite and the photocatalytic activity of ZnO, where adsorption dominated MB removal while photocatalysis contributed to enhancing overall degradation efficiency. The novelty of this study lies in the utilization of synthetic Indonesian montmorillonite as a ZnO support, which enhances photocatalytic efficiency while reducing production costs. This finding highlights the potential of MMT/ZnO composites as an environmentally friendly and cost-effective alternative for dye wastewater treatment in the textile industry.
