Abstract

Lampung Province is known for its enormous potential for marine and fishery resources in Indonesia. This condition will support the supply of fish for making otak-otak. Vacuum frying otak-otak can increase its shelf life, so otak-otak products have the potential for export. This study aims to analysis the effect of temperature and slice thickness in vacuum frying on the quality characteristics of fish otak-otak chips. Frying temperature and differences in slice thickness affect the quality characteristics of fish otak-otak chips, especially on the parameters of yield, colour, and crispiness, but do not significantly affect water content, taste, and aroma. Treatment with longitudinal slices divided into 3 tends to produce a crispier texture and a higher level of acceptance than whole otak-otak. The combination of 85 °C temperature with longitudinal slices resulted in the fastest frying time, namely 85 minutes, with the lowest water content of 4.0%. In contrast, the treatment of 75 °C temperature with whole slices resulted in the longest frying time, namely 139 minutes, with the highest water content of otak-otak fish at 4.7%. The best colour quality was obtained at a temperature of 75˚C with longitudinal slices with a score of 3.78, while the highest level of crispiness was obtained at a temperature of 85 °C with longitudinal slices with a score of 4.25 (crispy).

Abstract

The utilization of biomass as a renewable energy source has gained increasing attention as an alternative to fossil fuels. This study aimed to evaluate the effect of tree branch biomass proportion on the physical characteristics and combustion performance of biocoal briquettes produced from biomass–coal blends. Four briquette formulations containing 16.0%, 31.9%, 47.7%, and 63.7% tree branch biomass were prepared and tested for density, impact resistance, tensile strength, compressive strength, and combustion rate. The results showed that biomass composition significantly affected the physical and combustion properties of the briquettes. The highest density was obtained at 16.0% biomass content (940.84 kg/m³), while the lowest density was observed at 47.7% biomass content (883.08 kg/m³). The briquette containing 47.7% biomass exhibited the best mechanical properties, characterized by the lowest number of fragments after impact testing (3.4 pieces), the highest tensile strength (115,710.61 N/m²), and the highest compressive strength (168,541.37 N/m²). Meanwhile, the highest combustion rate was achieved by the briquette containing 63.7% biomass, reaching 2.37 g/min. Compared with commercial coal briquettes, the combustion performance of the 63.7% biomass briquette approached that of super briquettes (2.57 g/min) and exceeded that of pure coal briquettes (2.09 g/min). Overall, a biomass proportion of 47.7% was considered optimal in terms of physical and mechanical properties, while 63.7% biomass provided the best combustion performance. These findings demonstrate the potential of tree branch biomass as a sustainable feedstock for biocoal briquette production.
