Abstract


Abstract
Biodiesel is still expected to be an alternative fuel other than petroleum. Therefore, intensive research is being done by researchers in the world to develop biodiesel production process that is more efficient, economical and environmentally friendly. Among them is by developing a catalytic and non-catalytic process. The heterogeneous catalytic process is of particular concern with many promising results and is expected to address the current lack of homogeneous catalytic processes. In Indonesia, many natural catalyst sources have been investigated into potential heterogeneous catalyst. The non-catalytic process also provides a reasonably reliable process expectation of course with its various challenges. Both heterogeneous catalytic processes and non-catalytic processes are believed to be potential processes that can be applied in the near future. The development of the results and the challenges of these two processes, therefore, is reviewed in this work as an innovative biodiesel process technology research opportunity.

Abstrak
Biodiesel masih diharapkan menjadi bahan bakar alternatif selain dari minyak bumi. Oleh karenanya penelitian yang intensif tengah dilakukan para peneliti di dunia untuk mengembangkan proses produksi biodiesel yang lebih efisien, ekonomis dan ramah lingkungan. Diantaranya adalah dengan mengembangkan proses secara katalitik dan non-katalitik. Proses katalitik heterogen menjadi perhatian khusus dengan banyaknya hasil penelitian yang menjanjikan dan diharapkan dapat mengatasi kekurangan proses katalitik homogen saat ini. Di Indonesia berbagai sumber katalis alami telah diteliti untuk dijadikan katalis heterogen. Namun, proses non-katalitik juga memberikan harapan proses yang cukup bisa diandalkan tentu dengan berbagai tantangannya. Baik proses katalitik heterogen maupun proses non-katalitik diyakini sebagai proses potensial yang dapat diterapkan dalam waktu dekat ini. Oleh karena itu, perkembangan hasil dan berbagai tantangan dari kedua proses tersebut diulas dalam tinjauan ini sebagai peluang penelitian teknologi proses biodiesel yang inovatif.
