This study aims to determine the effect of cowpea sprout paste and seaweed paste to the characteristics of analogue cowpea sausage, and to know the right ratio of cowpea sprout paste and seaweed paste on the characteristics of analogue cowpea sausage. The experimental design used was completely randomized design with the treatment ratio of cowpea sprout paste and seaweed paste, which consists of 5 levels such as: 90% cowpea sprout paste : 10% seaweed paste, 80% cowpea sprout paste : 20% seaweed paste, 70% cowpea sprout paste : 30% seaweed paste, 60% cowpea sprout paste : 40% seaweed paste, and 50% cowpea sprout paste: 50% seaweed paste. The treatment was repeated 3 times to obtain 15 units of experiments. The data were analyzed by variance analysis and if the treatment had a significant effect then continued with DMRT (Duncan Multiple Range Test). The results showed that cowpea sprout paste and seaweed paste ratio had a significant effect on water content, protein content, fat content, carbohydrate content, coarse fiber content, elasticity, taste (hedonic), texture (hedonic and scoring) and overall acceptance (hedonic). Comparison of 50% cowpea sprout paste and 50% seaweed paste had the best characteristics analogue cowpea sausage, with 69,88% water content, 2,16% ash content, 3,77% protein content, 2,92% fat content, 21,27% carbohydrate content, 1,50% coarse fiber content, elasticity 6,65 N, color and aroma rather liked, texture chewy and liked, taste and overall acceptance liked.

This research was conducted to determine the viability of Lactobacillus rhamnosus SKG 34 on various encapsulant and temperature. This research was divided into two steps. The first step, three kinds of encapsulant agent, i.e. maltodextrin, carrageenan, and alginate were used to microencapsulate Lactobacillus rhamnosus SKG 34. At this step, microcapsule yield, morphology, and viability of Lactobacillus rhamnosus SKG 34 was observed. Encapsulant with the highest population of Lactobacillus rhamnosus SKG 34 was extended into the second step. At the second step, microcapsule was treated with 7 variants of temperature, i.e. 45°C, 50°C, 55°C, 60°C, 65°C, 70°C, and 75°C. Data obtained were shown and explained with descriptive method. The result of the research showed that encapsulant variety gave different effects on microcapsule yield, morphology and viability of Lactobacillus rhamnosus SKG 34. The highest population produced by maltodextrin (1,24 x 109 ± 0,33 cfu/gr). The highest viability obtained at 45°C (3,37 x 108 ± 0,14). Lactobacillus rhamnosus SKG 34 can survive at adequate amount to give functional effect to the body with maximum temperature 55°C (4,78 x 107 ± 0,31cfu/ml).
