Abstract

Fish and lobster embankment was main occupation of most of Lamongan regency people. So farthey always used fabricated pellet as a fish and lobster food. And this food supplied by broker.There was a dependency between people and broker. This dependency caused problem, thatwas, broker could rise up the price of pellet whenever he wanted. At the other side, the use offabricated pellet in long time will made embankment media in satiation condition. Thiscondition will made many fishes and lobsters died in growth period and the death up to 40%.Gapoktan was a group of people who explored and invented the alternative fish and lobsterfood. This alternative food was made of natural raw material so it reduced the death until 20%.With this alternative food they wanted to be independent in fish and lobster food procurement.They wanted have alternative pellet. But they didn’t have sciences and technologies to make it.This research was designed to overcome their problem. Designing the extruder machine was theanswer of their problem. Designing was done based on the ergonomic concepts. Finally, wasknown this machine capacity up to 672 kg/day. It means that the machine could fulfill theminimum need of fish and lobster food. There were two variance of diameter of pellet, that wasfive and three millimeters with five until ten millimeter long. With this alternative pellet, theycould save 50.8% food procurement cost or equal Rp 6,097/kg.Kata kunci: rancang bangun, mesin granul, pakan ikan dan udang

Abstract

Mung bean (Phaseolus radiatus L.) is one kind of nuts that have been widely knownthroughout the community. Mung beans contain high nutrient value, so it has the potential to bedeveloped into refined products such example is a highly nutritious vegetable milk. This studyaims to determine the effect of age of sprouts and Na-CMC concentration on the quality of milkproduced mung bean sprouts. The research method using a randomized block design (RBD),which consists of two factors and factorial arranged. The first factor is the age of sprouts (K)which sprouts 12 hours, 24 hours and 36 hours. While the second factor is the concentration ofNa-CMC (N) of 0.2%, 0.3% and 0.4%. From each treatment was repeated three times. Analysisthat used to milk mung bean sprouts are the levels of protein, vitamin C, fat content, viscosity andorganoleptic test consists of aroma, flavor and color.The results showed that there was no significant interaction between the two levels of afactor. At the age of sprouts showed treatment differences were highly significant effect on levelsof protein, vitamin C and viscosity, but did not show significant differences in the effects on fatcontent. While treatment concentrations of Na-CMC manunjukkan no significant difference in theeffect of the protein content, vitamin C, fat content and viscosity, but the addition of Na-CMCconcentration can increase the viscosity of milk. Organoleptic assessment results showed that thetreatment of the aroma that gets the highest percentage was K1N1 (sprouts aged 12 hours at aconcentration of 0.2% Na-CMC), treatment K1N3 (sprouts aged 12 hours at a concentration ofNa-CMC 0.4%) received the highest percentage the flavor while for the color treatment that getsthe highest percentage was K1N3 (age sprouts 12 hours with concentrations of Na-CMC 0.4%)and K2N3 (age sprouts 24 hours with concentrations of Na-CMC 0.4%).Kata kunci: kacang hijau, susu kecambah kacang hijau, umur kecambah, kosentrasi Na-CMC
