Jurnal Keteknikan Pertanian dengan No. ISSN 2338-8439, pada awalnya bernama Buletin Keteknikan Pertanian, merupakan publikasi resmi Perhimpunan Teknik Pertanian Indonesia (PERTETA) bekerjasama dengan Departemen Teknik Mesin dan Biosistem (TMB) IPB yang terbit pertama kali pada tahun 1984, berkiprah dalam pengembangan ilmu keteknikan untuk pertanian tropika dan lingkungan hayati. Jurnal ini diterbitkan dua kali setahun. Penulis makalah tidak dibatasi pada anggota PERTETA tetapi terbuka bagi masyarakat umum. Lingkup makalah, antara lain: teknik sumberdaya lahan dan air, alat dan mesin budidaya, lingkungan dan bangunan, energi alternatif dan elektrifikasi, ergonomika dan elektronika, teknik pengolahan pangan dan hasil pertanian, manajemen dan sistem informasi. Makalah dikelompokkan dalam invited paper yang menyajikan isu aktual nasional dan internasional, review perkembangan penelitian, atau penerpan ilmu dan teknologi, technical paper hasil penelitian, penerapan, atau diseminasi, serta research methodology berkaitan pengembangan modul, metode, prosedur, program aplikasi, dan lain sebagainya.

Abstract

Many,freezing methods, mechanicul as well as cryogenic, have been in wide application in food industries. Each method has its own advantage, but in regard with the food quality, freezing rule can be accomplished by the method is one of the tnost important factors. Nowadays, many researchers are conducting experiment in order to enhance thefi.eezing rate. This paper deals with the advantage of vacuum freezing method in enhancing the freezing rate and its applicability for liquidfood.Experinrent was carried out for distilled water, milk, and fruit juice using multi-purpose vacuum equipment. As easily predicted, minimum pressure of the freezing chamber determine temperature of the product. Vuriation on the fruit juice concentration shows that faster freezing rate canbe achieved if the product is more dilute. The experiment also showed that freezing rute obtained by vacuumj-eeziirg was signijkantly faster than contact plate freezing method.

Abstract

Ihe research was done to design computer sojiware for land suitability identification offood crops, i.e.: wetland rice, upland rice, maize, soybean, phaseolus bean, sweet potato, cassava, white potato, and cocoyam/taro using Quick BASIC.After having user input the data of certain physical characteristics of the land, the system examined the program and then the system was capable to give the rank of the crops with certain score. The crop with the biggest score is the most suitable crop for that land.

Abstract

A database system has been developed to prodict land suitability and cultivation information of national valuable fruits. The database system covers commodity of fruits database, agro-ecological database, and salaccia and mango information database. "A computer program for determining the best of land suitability was designed based on fruits database and agroecological database.

Abstract

The objective of the research is to build the setup model of farmmachinery and equipment for zip land sugar cane indzlstry. From this model can be determined: (I) selection of farm machinery/equipment, (2)number farm machinery/equipment, and (3) optitnun? longevrty of ratoon.The result shows that the technolog?, consideration hus been the priniary consideration on farm tnachinery and eqztipnzent selection. The next is econonzy consideration. The attention for social and environment consideration is poor.

Abstract

This paper describes an application of n~rmerical method of finilsdzflerence for predicting the distribution of volumetric water (8) and water potential (v by using diffusity and conductivity approach. The result of current study showed that the parameters, volumetric water and water potential, correlated reversely. The trend of application of numerical method was similar to that of exact method. The simulation of parameters was not signiJcant. The reliability of models is still needed to test emperically.
