About Journal

Jurnal Keteknikan Pertanian (JTEP), previously named Agricultural Engineering Bulletin, is an official publication of the Indonesian Society of Agricultural Engineers (ISAE) in collaboration with the Department of Mechanical and Biosystem Engineering, Faculty of Agricultural Technology and Engineering, Bogor Agricultural University (The MoU can be downloaded here). JTEP is published three times a year in April, August and December.

JTEP is a peer reviewed journal that has been accredited SINTA 2 by the Ministry of Research, Technology and Higher Education Number 30/E/KPT/2018 which is valid for 5 (five) years since enacted on 27 September 2018. JTEP has been registered in Crossref, Indonesian Publication Index (IPI), Google Scholar, and other scientific databases.

JTEP receives manuscripts of research results or scientific review in agricultural engineering related to farm structures and environment, agricultural and biosystem engineering, renewable energy, postharvest technology, food engineering and agricultural information system.

The articles sent by the author - must be an original script and is not being considered for publication by other journal or publishers - should be written in accordance with the writing guidelines and submitted online via https://journal.ipb.ac.id/index.php/jtep. Editors can revise the paper without changing the substance and content after a blind review process.

The more important limitation in process design for agricultural products is the lack of information on their thermal properties. Although a lot of experimental data can be found, the variety of product and the differences ij measurement method make limitation on the value of the available data, especially for indonesia'a products. These data are needed to get information about temperature change when product was processed like hetaing or cooling. It is worth to optimize efficiency of energy. The objective of his study is to predict thermal diffusivity and conductivity of carrot. The value was determined numerically with direct and indirect methods. The result shows that thermal conductivity is 0.626 W/moC while thermal diffusivity are 2.51 x 10- m2/s (indirect method) and 2.08 x 10- 7 m2/s (direct method)
