Journal ArticleDOI
Synthesis of Biodiesel from Second-Used Cooking Oil
TL;DR: In this article, the authors studied the kinetic reaction of second-used cooking oil transesterification into biodiesel and found the optimum condition of its process, which is based on free glycerol analysis, total glycerols analysis, free fatty acid analysis, and saponification analysis.
Journal ArticleDOI

Arif Hidayat,Rochmadi,Karna Wijaya,Annisa Nurdiawati,Winarto Kurniawan,Hirofumi Hinode,Kunio Yoshikawa,Arief Budiman +7 more
TL;DR: In this article, the authors used a coconut shell biochar (CSB) catalyst to convert free fatty acids (FFA) into biodiesel, and the optimal conditions were an methanol/PFAD molar ratio of 12:1, the amount of catalyst of 7%wt and reaction temperature of 60oC.
Journal ArticleDOI
Technological Evaluation of Municipal Solid Waste Management System in Indonesia
Hanifrahmawan Sudibyo,Akmal Irfan Majid,Yano Surya Pradana,Wiratni Budhijanto,Deendarlianto,Arief Budiman +5 more
TL;DR: In this article, three thermal based technologies are available for waste to energy (WtE) which are incineration, conventional air gasification, and plasma gasification and their feasibility was evaluated environmentally and economically.
Journal ArticleDOI
Highly energy-efficient combination of dehydrogenation of methylcyclohexane and hydrogen-based power generation
Firman Bagja Juangsa,Lukman Adi Prananto,Zahrul Mufrodi,Arief Budiman,Takuya Oda,Muhammad Aziz +5 more
TL;DR: In this article, the authors investigated a power generation system from H2 storage in MCH, involving the dehydrogenation process and the combined cycle as a power generating process, and the proposed system demonstrated a system efficiency of 53.7% under similar conditions as the Graz cycle based system.
Journal ArticleDOI
Torrefaction of Indonesian sugar-cane bagasse to improve bio-syngas quality for gasification process
TL;DR: In this article, an experimental investigation of torrefaction process of Indonesian sugarcane cane bagasse was conducted, and the authors found that the optimum temperature of dry torrefactions is 150 °C.
