Abstract

Dielectric heating has received a lot of attention recently. Microwave heating, however, has the problem of noticeable hot and cold spots within a food. Radio frequency (RF) has the potential to overcome this problem because of its longer wavelength and greater penetration depth, which would lead to more uniform distribution of the electric field and thus a more uniform temperature distribution. The dielectric properties are the measure of a sample's response to an electromagnetic field, which vary significantly with frequency, temperature, moisture, and salt content. The potential of a medium to respond to dielectric heating can be characterized by its dielectric properties, which can be strong functions of frequency and temperature. This experiment is aimed to design and test the performance of a measurement apparatus for the dielectric properties, using the Q-meter method.

Abstract

Trickle irrigation is an irrigation method which can give continuous water drops at the root zone. The main components of Trickle Irrigation System are  : emitter. lateral pipe, manifold pipe, main pipe, water pump and other supporting components.The design is using point source type of emitter. Each emitter serves 4 pepper plants. The total power consumption at pump station III is 8.4 KW. The total operation of pump station I is 752.I hrs/ season, pump station II is 2256.2 hrs / season and pump station III 1504.I hrs / season.

Abstract

This paper presented a particle size effect on model retaining wall by comparing the experimental and finite element analysis. The experiments were conducted with air-dried Toyoura sand and Soma sand plane strain condition, both sand are standard sand in Japan. The wall was oved horizontally into sand. The hights of sand mass in these experiments were 5 cm, 10 cm, and 15 cm. The finite element analysis employed a constitutive model in which non-associated strain hardening-softening elasto-plastic materila was employed. This analysis introducted the effect of shear band thickness. The result obtained from the finite element analysis showed a good agrement with the results obtained from the experimental investigation. From both experimental and analytical results, there was evident of particle size effect due to shear banding.

Abstract

This paper describes the design of baby fish counter with parallelsensors to enhance the speed of counting process. This design is developed from the previous baby Jish counter with a single sensor. The counter with 0 single sensor has only one outlet channel through which baby fishes are being $own and counted. The new baby fish counter is designed to have multiple outlet channels, each of which is equipped with a sensor to enable uparullel counting process, and thus increasing the counting speed.

Abstract

The final step of this research was uploading the system in virtual FTP (File Transfer Protocol directory address /www/smipipb, and Uniform Resource Locator (URL) to access this site washttp://www.websamba.com/smipipb. The eveluation using the same browser engines indicutes that the system work as weN as in the local intranet. The knowledge base contains rules concerning the knowledge domain transformed and stored in the Microsoft Access data basejle. The main constribution of this research is to provide a multiuser software tool for hand tractor trouble shooting in the internet environment.

Abstract

This research tries to find a suitable material for porous lateral pipe, its mean outflow, its coefficient of uniformity and distribution of outflow along the pipe. The material that is used in this research is Parachute and Fatnatex cloth with 20 cm long.The research shows that the Famatex cloth with 8 cm circumference, gives a better performance and can be used for the further research . Besides. the bigger head is used, the faster water flow and the bigger mean outflow from the material to the ground surface.

Abstract

Sejak jaman kolonial hingga saat ini, keberadaan petani masihdianggap sebagai factor produksi (produsen), yang terus menjadi sapi perahan (ekosloitasi) bagi pelaku bisnis pertanian yang bergerak pada pengadaan saprodi (sarana produksi), pasca panen dan pemasaran hasil, sehingga petani tak berdaya untuk bergerak dari pola usaha tani tradisional yang bersifat subsisten menuju usaha tani moderen yang bersifat komersial. Petani berada dalam posisi "pasrah" menerima dan mengikuti perilaku dan mekanisme pasar yang belum memihak kepada petani, yang menyebabkan tingkat kehidupan petani relatif statis berada pada lapisan bawah sehingga semakin sulit untuk mampu keluar darikondisi kerniskinan dan keterbelakangan.

Abstract

Palawija is still used as secondary food in Indonesia. Some of palawija crops were source of the carbohydrate, and the others like a peanut and soybean are source of protein. The common palawija crops grown on upland area are soybean, peanut, green pea, and corn. The major constrains on development of upland area for agriculture purpose was water scarcity and availability data of crops water requirement. The objective of the research was to develop the crop growth and water use modeling, determining the transpiration coefficient and crop water requirement of upland crops.
