Abstract

The purposes of this research were investigated the physicochemical and sensory characteristics of snakehead fish ball with yellow velvetleaf addition. The research was conducted on January until March 2016. The research method was used randomized block design (RBD). The treatments were 0%, 5%, 10%, and 15% of yellow velvetleaf addition. The parameters of this research was chemical analysis such as water content, ash content, protein content, lipid content, carbohydrate content, and fiber; physical analysis were elasticity; colour and sensoric analysis (texture, taste, colour and aroma). The results showed that treatment gave significant effect on ash content, water content, ash content, protein content, and fiber content; lightness and sensoric analysis (taste and colour), but there were no effect to lipid content, carbohydrate content and elasticity, chrome and hue. The concentration of water, ash, protein, and fiber were 63.32%-69.27%, 1.21%-6.44%, 14.69%-20.61%, 0.93%-5.65% respectively. The lightness of this fish ball were54.23%-6676%. Color sensory analysis of fish ball were 3.28-3.86 and taste were 3.17-3.36. The best treatments were A2 (10% yellow velvetleaf addition).

Abstract

The purpose of this research was to utilize water hyacinth biomass and sneakhead waste as substrats for biogas production as a renewable energy source by different treatment on substrate composition. This research used experimental method in anaerobic batch reactors with Liquid Displacement and Atomic Absorbtion methods using NaCl and NaOH solutions. The results in this research were analyzed by descriptive method. The observed parameters were rate and accumulation of biogas and methane production, and slurry’s parameters such as themperature, pH, BOD, COD, TS, VS, and C/N ratio. Results showed that the difference of substrates composition in reactor A produced the highest biogas and methane accumulation. Whereas in reactor B produced the highest methane percentage.
