The purpose of this research was to determine the physical, chemical, functional properties, and hydrogen cyanide content of jack bean sprout (Canavalia ensiformis L.) flour. This research used two treatments that was without germination and 48 hours of germination. The treatments were repeated three times resulting in six units of experiments. Jack bean flour and jack bean sprout flour were analyzed by paired T-test. The results showed that the germination of jackbean had a very significant effect on the decrease of oil absorption from 1.59 mg/l to 0.79 mg/l. The treatment had a significant effect on the increase of water content from 11.10% to 11.77%; increase of protein content from 28.52% to 29.18%; decrease of fat content from 6.33% to 5.54%; decrease of carbohydrate content from 51.19% to 50.77%; increase of crude fiber content from 11.69% to 12.30%; increase of water holding capacity from 1.42 ml/g to 1.58 ml/g; decrease of swelling volume from 8.97 ml/g to 8.31 ml/g; increase of solubility from 0.06% to 0.07%; and decrease of hydrogen cyanide content from 14.13 mg/kg to 11.00 mg/kg. This research had no effect on bulk density and ash content. Keywords : hydrogen cyanide; jackbean sprout flour; chemical, functional and physical properties

The aim of this research was to know effect the ratio of pulp and peel of a dragon fruit to the characteristic of jam, and determine the best the ratio made by those pulp and peel, in order to able to produce a good characteristic of jam. This research used Complete Random Design with the treatment comparison of pulp and peel of dragon fruit comprised of 5 (five) treatments, such as 90% pulp : 10% peel, 70% pulp : 30% peel, 50% pulp : 50% peel, 30% pulp : 70% peel, 10% pulp : 90% peel. All of treatments were repeated for 3 times to obtain 15 research units. Data were analyzed using analysis of variance and if an influences occurred among the treatments, the research would be continued to the Duncan’s test. Results of this research had showed that the comparison ratio of pulp and peel of dragon fruits gave influences to the water content, total sugar, total soluble solid, viscosity, pH balance, antioxidant capacity, color, flavor, texture and overall acceptance of a jam. The best ratio of pulp and peel of dragon fruits showed of percentage 30% pulp : 70% peel with 33,42% water content, 31,85% total sugar, 64,80%brix total soluble solids, 0,015% antioxidant capacity, viscosity 0,053 cm/second, 3,99 pH, aroma (normal), color, flavor, texture and overall acceptance (like).

This study aims to gather information of various banana corm effects to the characteristics of lawar. The RBD with single factor was used in this reseach. The type of banana corm used as a treatment that, consist of 6 level ie :raja banana corm, susu banana corm, kepok banana corm, emas banana corm, klutuk banana corm, and muli banana corm. Each treatment was repeated three times to obtain 18 experimental units. The variable observed were : proximate analysis (moisture, ash, protein, fat, carbohydrate), crude fiber, tannin, and sensory analysis ( color, aroma, texture, flavor and over all acceptance). The data ware analysed by ANOVA test with a 5% significant level. If there was impact on the research, the analysis would be followed by Duncan's Multiple Range Test (DMRT). The results showed the use of various of banana corm give the significant effect to characteristics of lawarie : proximate, crude fiber, tannin, and sensory properties. The best characteristics of lawar banana corm is resulted by klutuk banana corm (B5) which has moisture content 71.21%, ash 1.82%, protein 3.83%, fat 13.63%, carbohydrate 5.14%, crude fiber 10.33%, and tannin 0.28%.
