This BioDiesel miniplant was assembled by one of the TRKI lecturers named M Endy Yulianto, ST. with 18 students. In the design, this biodiesel miniplant is installed with a capacity of 1000 L per 8 hours. The raw materials used are multi-fuel which can be used for various types of oil, including Crude Palm Oil (CPO), Red Palm Oil (RPO), castor oil, candlenut oil and many more.
Currently, the biodiesel miniplant operating at the Vocational School of Diponegoro University uses used fuel in the form of used cooking oil. Basically, this tool consists of three stages of the process, including the following.
- Preparation of raw materials consisting of filters
- The reaction section includes the transesterification reactor and the esterification reactor
- Purification of biodiesel aims to ensure that the biodiesel product obtained meets specifications by releasing glycerol and other impurities.
Even at TRKI Undip Vocational School also has distillation that can be used to recover excess biodiesel as feed in reactors, both transesterification reactors and esterification reactors. On the other hand, we also partner with PT. Bhanda Ghara Reksa (BGR) which is engaged in logistics with a fleet of 1500. Where, PT. This BGR utilizes our biodiesel as its fuel supply. In addition, from this collaboration we obtain raw materials in the form of used cooking oil with an online system so that it is easier and more fulfilled.
“Alhamdulillah, our Undip Vocational School can cooperate with PT. Bhanda Ghara Mutual (BGR) in Semarang. We hope that from this collaboration, we will get biodiesel production which has been separated from glycerol and other impurities,” said Endy.
Not only that, this activity also provides provisions for students by being able to operate this tool and be certified competently so as to improve the quality of education in Indonesia to be ready to work in accordance with the realization of the 17 indicators of the Sustainable Development Goals (SDGs) which are ‘Quality Education’.
