Nowdays, greenhouse is becoming popular in tropical country for plant cultivations, which the main reason is fbrplant protection against unwanted distwbances i.e. from heavy rainfall, wind, pest and so on. Since most of the greenhouse are covered with transparence material such as glass plate, plastic sheet, fiberglass etc., the greenhouse effect will take place accordingly causing a temperature rise that is usually higher than that of the outside. It turns out that this rising temperature becomes a major problem that will have negative effects on the plant growth. This research aims to control the temperature in the greenhouse by applying a Fuzzy Logic Controller (FLC), first by maintaining a constant temperature in the greenhouse and secondly, by trying to equalize the temperature in the greenhouse to that of the outside. The experiment was canied.out at a small scale with the greenhouse dimension of (1 00 x 120 x 100) c d Heet fnun the greenhouse was expelled using an exhaust fan. The power of the fan was: contfv&d.by the FLC subjected to the real temperaturn changes with time. The results sh~wtha t the FLC could pe~formg oad function of a temperature controller for the greenhouse.. It couM control the temperature in the greenhouse under the expected conditions end explained the energy consumption throughout the process.

During vegetative growth period, sugarcane required a lot of water but decreasing afterward and minimum at ripening period. Sugarcane water requirement was calculated by radiation method and USDA (1969) method was used to determinate effective rainfall. Average of monthly actual evapotranspiration (ETa) was calculated by the available soil water index. The total of water requirement of sugarcane (1-12 month) was around 37.38 mmlmonth to 143.22 mmlmonth. The highest water requirement was found at age of 4 to 9 month, while the lowest was in the ripening period. Accordingly drip irrigation should be operated at maximum water use of about 3.96 mm/day, or by sprinkle irrigation not less than 118.70 mm/mounth.

Baru-baru ini Gustav Grob (1996) mengingatkan lagi prediksi Club of Rome di awal tahun 1970-an bahwa bahan bakar fossil, yang sifatnya meneemarkan lingkungan, dan tak terbarukan kian berkurang keberadaannya dan dalam waktu dekat harus diganti dengan sumber energi terbarukan yang lebih bersahabat dengan lingkungan seperti sumber-sumber energi surya, biomassa, angin, hidro, dll. Ketergantungan kita atas bahan bakar fosil mungkin akan berlanjut sampai beberapa dekade lagi tetapi dalam jumlah yang jauh lebih kecil dari apa yang di konsumsikan sebelum tahun 2000 seperti terlihat pada Gambar 1 (Grob, 1996)

Crude palm oil is one of export comodities of Indonesia. Theme, it is of crucial importance to improve the quality of crude palm oil (CPO) through the process of CPO production. This paper discusses the design and implementation of an automatic process control for crude palm oil clarification. The automatic control system proposed herein is suppoded by a computer which performs intensive computation to determine the correct volume of water required for a CPO clarification process. The computer is also used to monitor and maintain a desired temperature during the process. The implementation results indicate promising performance of the system control.

The goal of the housing programme is to realize affordable or low cost housing construction for low income society, to improve access to basic services in urban and rural areas and promotion of local building materials. Waste material of rice straw is potential to be used as building materials becaue it contains fibres, SiD2 (if it is mixed with cement, it is possible to form calcium silicate hydrate), wax, pentosan, and lignin. This material is relatively cheap and easiZv available ill the immediate vicinity. The addition of organic materials of the rice straw ill manufacturing panel board is intended to improve the panel quality such as strength, light weight, an thermal properties.

Freeze drying of food materials is a time and energy consuming process, hence a high cost process. The drying rate is limited by heat and mass transfer process within the dried portion of the product. In order to improve the freeze drying performance, it is important to know parameters which affect the drying characteristics of each spesific food material, in regard to the drying time and the energy consumption. The objective of this experiment was to study the freeze drying characteristic of miched beef especially the effect of freezing rate and surface temperature of the material to the drying time.

The study was conducted with freezing rate at 7.71 cmhours and 1.94 cmhours which are classified into fast and slow freezing rate, while the surface temperature of the material was controlled at 40 OC, 35 OC, and 30 OC. The experimental results confirmed that the faster freezing rate then the longest drying time, while the higher surface temperature give a shorter drying time of miched beef. It is important to determine the optimal freezing rate and surface temperature from the view point of energy consumption.

This paper concerns with the development of a decision support package for chipper allocation at the transmigration land preparation area. It is intended to be used by chip entrepreneur on determining the most economical chipper allocation and man power requirement.

The package was developed by using Turbo Pascal, running well on the computers compatible with ISM PC (XT or AT) with minimum 640 Kb RAM and VGAISuper VGA monitor. Program testing showed that the program has a sufficient capability as a management tool.

Terminologi traktor beserta peralatan dan pengoperasiannya atau yang berkaitan dengan traktor, umumnya berasal dan berkembang dari negara-negara pembuat dan pengembang traktor pertanian. Ide awal dari penyusunan terminologi ini berasal dari usulan Prof. Dr. Jun SAKAI (JICA expert), dan diterima dengan baik oleh staf Laboratorium Alat dan Mesin Budidaya Pertanian, Jurusan Teknik Pertanian, FATETA, IPB, yang juga melihat perlunya penyusunan terminologi di bidang keteknikan pertanian agar orang-orang yang bergerak di bidang keteknikan pertanian berkomunikasi dalam istilah dengan pengertian yang sama.
