Jurnal Konversi Energi dan Manufaktur (JKEM) is published by the Mechanical Engineering Vocational Education Study Program (Program Studi Pendidikan Vokasional Teknik Mesin) of the Faculty of Engineering UNJ (Fakultas Teknik UNJ) every six months in April and October. The purpose of this journal is as a medium for lecturers, researchers and practitioners to discuss the results of their research in mechanical engineering. Each article that is submitted will go through a review process before it can be determined as suitable for publication. The editorial team will decide for each article that comes in whether the article fits the JKEM scope for the next review process.
