The application of the research results was carried out on the program of application of appropriate technology for automatic fish feed and automatic bird repellent on the Minapadi jajar legowo system which is a system of planting rice with fish cultivation in one rice field area simultaneously and the jajar legowo planting system with a spacing of 25 cm . The technology used is automatic feeding and automatic bird repellent. Automatic feeding is done by using a mini water pump that has been modified with the help of a digital timer so that the feed automatically dispenses the feed at the time we specify, which is 3 times a day. The second technology is automatic bird repellent using extracts of herbal ingredients (jengkol) with the help of an automatic sprayer. This technology aims to increase the income of farmers with high productivit...

Problems when it was a necessity of a salt with the quality of both in indonesia still rely on imported from foreign. It was because the qualities of a salt was still a lot of those managed in a traditional that is by using the light of the sun directly. To increase production salt needed latest technology able to return production land damaged quickly.Technology TUF geomembrane is technology is very effective used to a reservoir.Besides geomembran, the use of threaded filter used to fasten the process of crystallization will be quickly and the qualities of a salt whiter and not need to laundering salt.Produce a salt with that is only enough 7 to 10 the day the process drying be crystallization with good qualities.

The increasing demand for snakehead fish on the market has resulted in the addition of cultivated land and water use. Aquaponics technology was a combination of fish farming and plants that grow without soil media. The aim of this research was to determine the best composition of probiotics that can be used in aquaponic technology to optimize growth rate and feed conversion of snakehead fish (Channa sp.). This research used an experimental method. The experimental design used was a completely randomized design with four probiotic combination treatments and each treatment was repeated three times. The results showed that awarding of different probiotic compositions in the aquaponic system resulted in a spesific growth rate that was not significantly (P>0.05) different between treatments. The highest value of spesific growth rate were in the treatment ...

The method used in this research is survey method. The result showed that the types food of layur are small shrimp with a percentage value of 35%, then a small fish with a value of 17% and pulverized fish with a value of 48%. Frequency of occurrence type food obtained is 44% pulverized fish, small shrimp 37% and the lowest percentage of appearance food is small fish by 19%. IP value of small shrimp at 35% and the lowest part small fish by 9%, and then RLG of layur acquired intestinal length relative 0.91, intestinal length 32 and total length of 35 cm. Based on the value of RLG is less than 1, then the layur (Lepturacanthus savala) is a carnivorous (carnivores).
