Welcome to

Laboratory of Electrical Energy Conversion and Power System

In this brief outline, we would like to invite you to look inside the description of laboratory mission, history and activities that contain of laboratory practices, research, training & services

Mission

As a part of Electrical Engineering Department of Engineering Faculty of Diponegoro University, Electrical Energy Conversion and Power System laboratory has three significant roles to play as they are:

  • Conducting laboratory practices as apart of teaching and educational responsibility to ensure deeper understanding of the student about their subject of lectures.
  • Conducting research in field of electrical utilization related to industrial development. Students and lectures are facilitated to conduct research whether as individual research or joint research in the laboratory.
  • Conducting society services related to electrical utilization. By this services collaborative program or research are possible to conduct in order to solve the problem within in electrical utilization for residential or industrial application.

About Us

Electrical Energy Conversion and Power System Laboratory formerly was established as integrated laboratory of Electrical Department of UNDIP in year 1983.  All the laboratory practice for student who chooses electrical power concentration was conducted in the same laboratory within students of electronics concentration in Kampus Pleburan – UNDIP (Down town – Semarang). In year 1997 when Electrical Engineering Department had to move to the new location in Tembalang (Up town-Semarang), laboratory practices for student of electrical power concentration was conducted for the first time in the separated room as the new laboratory. This was the year when Electrical Energy Conversion and Power System Laboratory become self-laboratory in Electrical Engineering Department. Ir. Karnoto had become the chief of laboratory when it conducted the first laboratory practice in Campus Tembalang.

Several lecturers have been elected as chief of laboratory since Electrical Energy Conversion and Power System Laboratory was established as self-laboratory. They were

  • Ir. Tedjo Sukmadi
  • Ir. Joko Windarto
  • Ir. Bambang Winardi
  • Ir. Karnoto
  • Mochammad Facta
  • Ir. Hermawan, DEA, Ph.D

Since 2004 through unanimous election, Ir. Hermawan, Ph. D has become chief of Electrical Energy Conversion and Power System Laboratory.

In the year 2005 the chief of laboratory is Mochammad Facta and the secretary of laboratory is Ir. Abdul Syakur, M.Eng.

Since 2009 up to now 2011 the chief of laboratory is Ir. Hermawan, Ph.D and the secretary of laboratory is Ir. Karnoto, M.Eng.

In line with the mission to conduct education, research and social services, the laboratory has several activities regularly conducted. Those are:
