Abstract

Many alternatives have been made to Minimalized energy usage. One of them performs exergy analysis and exergoeconomic analysis. This concept of analysis, not only taking into account the quantity of energy but also the quality of the energy (the second law of thermodynamics). Exergoeconomic analysis, is an analysis that combines the exergy analysis with an economic approach (cost). Exergoeconomic analysis was done by taking data at PLTBg Tandun. The analysis was initiated by conducting economic analysis. Analyses conducted to figure out the total value of the waste from the Diesel PLTBg per year and the price of electricity/kWh. There ware 3 aspects of costs that we calculated cost of investment, operational maintenance fix costs, (employee salaries and benefits), and the operational maintenace. Of the each variable cost value were, the investment costs $0.016/kWh, for to investment cost $0.030/kWh, OM Fix the cost $0.009/kWh variable OM. The value of total cost loss for gas engine due to the destruction of the first period exergy is $7.116/hour, They are cost of losses for each component is the fuel space worth $7.09/hour, for combustion chamber, $0.043/hour, for compressor, $0.033/hour for turbocharge. While total cost loss value due to destruction of exergy the second period is $5.626/hour. They were of losses for each component is the fuel space worth $5.22/hour, compressor $0.393/hour, turbocharge $0.013/hour. Keywords: exergy, exergoeconomic, gas engine, biogas

Abstract

This study focuses on the design and development of a smoking device aimed at enhancing the quality and production efficiency of smoked fish. The primary objective was to create a device that optimizes the smoking process, ensuring consistent product quality while increasing production capacity. The development process involved a systematic design approach, including the selection of materials and construction techniques. The smoking process utilized a combination of drying and the application of natural smoke compounds derived from the combustion of organic materials. Performance testing was conducted using catfish as the primary substrate, with measurements taken for smoking duration, moisture content, and production rate. The effectiveness of the device was evaluated based on sensory characteristics, including texture, color, and aroma. The smoking apparatus was constructed with dimensions of 126 cm x 100 cm x 180 cm and is capable of accommodating up to 32 kg of fresh fish per smoking cycle. Results indicated that the smoking device achieves a production rate of 4 kg of smoked fish per hour, yielding products with a desirable golden-brown color and distinct smoky aroma. The findings demonstrate that the device significantly improves production capacity and allows for enhanced control over smoking conditions, contributing to greater consistency in product quality.
