Abstract

Sumberbrantas is an Agroindustrial village in Malang, East java, with the main commodities are potatoes. One of the farmer groups engaged in potatoes agricultural sector is Anjasmoro farmer groups III. This farmer groups special program is perform independently potato seeding in the greenhouse. But, this process is not optimal because of less lighting so the potatoes seed produced susceptible to disease and has a small size. Therefore, we innovate to apply LUMOS technology. LUMOS is an automatic lighting system based on photoperiodic. The purpose of this program is to determine a method of designing, manufacturing, Lumos application influences and effective way of socialization. Lumos has a size of 25m × 5m. there are 4 18 watt lights, there are control Box size 15cm × 21cm × 5cm, and can be used for 5 years. Making Lumos begins with assembly hardware, sensor calibration and software development. The results showed that potatoes produced has a diameter of 8.128 mm and a mass of 31.3 grams greater than before. This technology is able to produce potatoes seed up to 7,000 seeds/period and profit reached Rp 20,169,000.00 annually. It is expected that this technology into a technology demonstration for other potato farmers in Indonesia.Keywords: automatic lighting, potatoes seeding, photoperiodic

Abstract

Fruit production in Indonesia has greatly increased year by year that is resulting in price fluctuation due to abundant products. The fruits possible to be rotten which decrease the sale value when the harvest time is unstable. One of the efforts for increasing the sale value of fruit is by making juice. The most important process of making juice is pasteurization. Ohmic heating pasteurization is one of pasteurization methods that can be utilized to pasteurize the juice. Thus, the juice pasteurization machine was created in particular design to pasteurize juice in small-scale. This study aims to determine the design of machine and the performance machine test, and to determine the efficiency of energy use of machine performance. Performance testing of energy efficiency of fruit juice pasteurization was carried out in an ohmic tube with a diameter of 3.55 cm and electrode spacing of 18 cm. The experiment used mango as a sample with the addition of water (2:1), the sample was pasteurized with 3 variations of electric potential included 220V, 385V, and 425V up to 800C. The highest energy efficiency up to 94%. It was obtained in voltage of 385 V with pasteurization time 130 s and the lowest energy efficiency up to 88%. It was obtained in voltage of 220 V with pasteurization time 369 s. The result showed that the ohmic-based fruit juice pasteurization machine was able to pasteurize in short time and had high efficiency.Keywords: Ohmic Heating, Efficiency, Pasteurization
