Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

According to data from World Health Organization, more than one million people died every year because of accidents that related to transportation. Meanwhile, according to data from KORLANTAS POLRI Indonesia, in 2018 there is 28.772 traffic accident. In order to prevent loss of lives in traffic accident, improve the safety standard of vehicle manufacturing, and to help investigate the cause of an accident. Vehicle Data Recorder (VDR) is designed and implemented in this research. The VDR is completed with engine monitoring system on demand. The system calculates the location from GPS, parsing data from OBD and then send it to server. The data transmission using GSM module worked well at outdoor with accuracy more than 70%. Meanwhile in-vehicle the accuracy of data transmission is more than 50%.
Biodiesel is one of the best choices for fuel alternatives. This is mainly due to its lower production value as it can easily be procured from cheap natural sources. It also has low emission of pollutant. However, some issues in regard to the production of biodiesel is that most production processes use homogeneous catalyst which is irretrievable and has expensive separation procedures. There is a method conducted to negates the outcomes stated above such as transesterification in supercritical conditions. But this method of transesterification also has its downside, high temperature and pressure processes indirectly will lead to higher cost and higher energy wastage. Therefore presently, using heterogeneous catalyst are the way to go, especially catalyst derived from green resources. These types of catalyst are being extensively researched on due to its versatility, wide range of resources and promising results. Thus, this paper illustrates the compressive studies of biodiesel synthesis and assesses the latest achievement involved in heterogeneous catalyst derived from waste specifically waste from animal sources. Experimental data from great number of papers are reviewed thoroughly to provide an easier framework in producing biodiesel. Most importantly this review aims to diminish problems associated with heterogeneous catalyst while helping the industry to sustain the environment while still meeting energy demands.
