Abstract

This study aims to identify and map the tempeh industry's supply chain to understand the economic pathway and carbon emissions. The research method uses a system-based approach with the output of a causal loop diagram that explores the dynamic relationship between variables in the small and medium scale tempeh industry supply chain. The results showed that the potential of the small and medium-scale tempeh industry in West Java is very high, especially in contributing to the economic value of the surrounding community. However, this potential has challenges regarding raw material procurement, where dependence on imported soybean raw material supplies makes the economic value for MSEs or the surrounding community not too large. This is due to the efficiency in the procurement of local soybeans and the inadequate stock of local soybean resilience to meet the needs of tempeh production in West Java’s supply chain. The findings also show that the longer the supply chain, the smaller the profitability and create more environmental impacts related to the carbon emissions generated. This study recommends a policy meeting to cut and streamline, and prioritize local soybeans and increase local soybean resilience stocks to better benefit tempeh SMEs in gaining profitability and minimizing the impact of carbon footprint risks, so that business and industrial activities are more sustainable.

Abstract

The textile modification process using plasma treatment requires accurate monitoring of gas species generated during operation; however, no system is currently available to measure these gas concentrations in real time. To address this gap, this study develops a plasma gas monitoring system for textile material modification, using experimental data obtained from laboratory tests conducted in 2024. The research employs a practical prototyping approach consisting of four stages: requirement identification, system design, prototype construction, and performance validation. The system is designed to continuously record plasma-generated gas concentrations and store the data in an internet-based database. The prototype consists of two main components: (1) a sensing unit built on an Arduino Uno microcontroller integrated with DHT-11 and MQ-131 sensors for measuring temperature, humidity, and ozone concentration, and (2) a data management platform using Google Spreadsheet connected to a mobile application to enable real-time monitoring and control. Evaluation results show that the monitoring tool achieved a Mean Absolute Error (MAE) of 0.6625 ppm, indicating that the system provides reasonably accurate measurements for initial validation. As this assessment is preliminary, future studies should employ a larger dataset to increase statistical robustness and further verify system performance. Overall, the findings contribute to the development of an accessible, Android-based plasma treatment monitoring system capable of supporting real-time monitoring in textile material modification applications.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in the angkringan-based coffee shop sector have significant economic potential; however, many of them still face challenges in production decision-making due to limited resources and the lack of data-driven planning. This study aims to optimize the beverage production mix at Coffee Suganda, an MSME coffee shop located in Majalengka Regency, which produces 25 product variants, with three main products: palm sugar milk coffee, creamy milk coffee, and chocolate. The research applies Linear Programming (LP) to maximize profit under constraints related to raw materials, production time and is further strengthened by sensitivity analysis to examine the robustness of the optimal solution under parameter changes. Research data were collected through field observations, interviews with the business owner, and records of production and sales activities. The results indicate that the Linear Programming approach provides a more optimal production combination compared to the existing conditions and improves resource utilization efficiency. The sensitivity analysis reveals that changes in raw material availability and selling prices significantly affect the optimal solution, highlighting the importance of adaptive production planning. This study contributes practical insights for angkringan-based coffee shop MSMEs in developing data-driven and adaptive production strategies, as well as academic contributions to the literature on MSME production optimization
