Abstract

This study aims to analyze the flow pattern of supply chain of jackfruits, supply chain performance, supply chain efficiency, and calculate the added value products of Jackfruits chip in Panda Alami Agroindustry.  This study is conducted purposely in Panda Alami Agroindustry in Gedong Tataan Sub-district of Pesawaran District. The data is collected in Februari 2017, performance measurements are made by comparing measurement indicators with FoodSCOR Card indicators.  Efficiency calculations are performed using a software deap 2.1, the calculation of value added is done by Hayami added value method.  The result showed that the flow pattern starting from the farmers as the main raw material supplier.  The performance of the supplier of Panda Alami Agroindustry was good, based on compared value of FoodSCOR card. Efficiency measurements indicated that only 37.5 percent of supply chain actors were already efficient for DMU farmers’ category, and 100 percent efficient for retail and agroindustry category.  The calculation of the added value of jackfruits chips of Panda Alami Agroindustry showed positive value, it meant that agroindustry was feasible to be developed.Key words: added value, agroindustry, efficiency, farmers, jackfruits, performance

Abstract

Plastic waste is a major environmental problem in Indonesia due to its non-biodegradable nature. One innovative solution is converting waste into energy using Refuse-Derived Fuel (RDF) briquettes for small-scale power generation. This research designed and tested an RDF-based micro power plant prototype using briquettes composed of 80% dry organic biomass and 20% plastic for safe and stable combustion. The prototype consists of a combustion chamber, heat exchanger, impulse-type micro steam turbine driven by low-pressure steam, and a 12V low-speed DC generator. Performance was evaluated through temperature, voltage, current, power output, and efficiency measurements. The highest performance was achieved using 500 g of RDF, producing 0.02 A, 0.7 V, and 0.014 W at 135°C over 20 minutes, with an efficiency of 2.69×10⁻⁶%. Although efficiency was very low, the study demonstrates proof-of-concept feasibility and provides a baseline for future optimization of thermal and energy conversion efficiency.
