Abstract

Rendang, a traditional Minangkabau dish from West Sumatra, Indonesia, has gained international recognition and has inspired many entrepreneurs to promote this cuisine globally. One such entrepreneur is CV. Kuliner Makmur Sejahtera (KMS), which produces rendang under the brand Katuju. To enhance operational efficiency and support global market expansion, KMS requires an improved inventory management system. The primary challenge is the difficulty in monitoring inventory and tracking products without a barcode system. This community service program aims to address this issue by implementing barcode technology on Katuju's product packaging. The activities include designing, creating, and printing barcodes, as well as training KMS staff on how to use them. The process starts with observation and interviews to identify needs, followed by barcode design and production using an online barcode generator, and testing the barcode functionality with a scanning system. The results indicate that the community service team successfully trained KMS in barcode creation and printing, and integrated barcodes into product packaging. Evaluation through questionnaires showed participant satisfaction with the program and readiness to apply the barcode system to their products. This program is expected to improve inventory management, data accuracy, and support CV. KMS's global market expansion by providing tools necessary for efficient product tracking and valuable consumer data collection.

Abstract

The palm oil industry plays a vital role in the national economy through palm oil mills (POMs) that process fresh fruit bunches into crude palm oil and packaged products. The Consumer Packaging (CPC) department ensures product quality, yet its tasks requiring high accuracy, speed, and consistency may cause mental workload. This study assesses and analyzes the mental workload of Consumer Packaging (CPC) operators in a palm oil mill using the NASA-TLX method, involving eight respondents from the forklift, Samarpan machine, packing, and stuffing units. The results indicate an average NASA-TLX score of 82% (very high category), with effort identified as the dominant dimension (26%). Simulation of additional workers reduced workload to 59.6%. These findings highlight the importance of task redistribution, workplace improvements, and temporary contract workers to maintain productivity and operational sustainability.

Abstract

The increase in household electrical energy causes shrinkage of energy so that efforts are needed to conserve energy, especially electrical energy. One attempt to reducing the scarcity of electrical energy is by changing behavior. Changes in the behavior of electricity consumption can be influenced by psychological factors (norms, awareness, etc.), demographic factors (age, gender, income, etc.), and other factors such as regulations or policies from the government to conserve energy. This study seeks to determine the effect of psychological and regulatory factors on the behavior of household electricity consumption based on age. The method used was to conduct a survey by distributing questionnaires, the respondents obtained were 808 respondents. The results of the questionnaire were processed using the Structural Equation Model Partial Least Square (SEM-PLS) using the Smart-PLS software. The results of this study indicate that psychological and regulatory factors can explain their effect on the behavior of electrical energy consumption for ages <30 years of 50.9%. For 30-50 years old it is 49.5% while those> 50 years old are 59.3% and the rest is explained by other factors / variables outside those that have been studied so that it can be concluded that psychological factors and regulatory factors have a significant and significant influence. positive behavior towards household electrical energy consumption at all ages. it is expected that the results of this study can become the basis for making stronger regulations or policies in the field of energy conservation.

Abstract

Hazard Analysis Critical Control Point (HACCP) ia a quality control system from the preparation of raw maerials to the product and accepted by consumers. HACCP is a requirement for guaranteeing the safety of food products produced according to company quality standards. PT. X produces packaged coconut milk as one of the main products and has implemented HACCP in every production process of its products. The packaged coconut milk that is produced often gets bloated in the finished product warehouse before the product is distributed. Therefore it is necessary to analyze the application of HACCP in the production of packaged coconut milk. HACCP application in the packaged coconut milk production process has set 4 Critical control points. CCP 1 (UHT Sterilization System & Aseptic Tank), CCP 2 (Filtration 500 micron), CCP 3 (Product Sterilization at 140-148ºC) and CCP 4 (Filling with Astepo Filler Filling Machine). Each Critical Control Point has physical and biological hazards, which must be controlled to ensure food safety. The research objective was to analyze the implementation of HACCP plan for coconut milk products based on SNI No. 01-4852-1998 regarding the HACCP system and analyzing the causes of product defects (bloating) in the determination of the CCP. Based on the analysis of HACCP application and the causes of product defects in packaged coconut milk, product defects due to bloating are not defects in the production process but defects caused by cross-contamination of microbes after filling. Cross contamination occurs due to cracks in the neck of the aseptic bag cup that cannot be detected directly, and the use of tools that should not be used during the filling process.

Abstract

Failures in the transfer carriage at the tippler station significantly disrupt material flow in palm oil mills, contributing to approximately 50% of total downtime during seven months of operation. This study aims to identify critical failure components of the transfer carriage system using the FMEA framework, analyze the root causes of these failures through the fishbone diagram and recommend maintenance improvement strategies. Data were collected through maintenance records, direct observation, and SOD questionnaires completed by three experienced personnel. Failure Modes and Effects Analysis (FMEA) was applied to prioritize risks, while a fishbone diagram was used to determine root causes. The analysis showed that bearing damage or broken had the highest RPN (189) and represented the primary cause of operational interruptions. Improvement actions including automatic lubrication, stricter inspections, operator training, and higher-quality bearing selection, are projected to reduce failure frequency and unplanned downtime, enabling a shift from reactive to preventive maintenance while improving asset utilization and production stability This study offers a structured, data-driven framework for enhancing equipment reliability in palm oil mills, with practical relevance for maintenance planning and resource allocation. Keywords: Palm oil mill; transfer carriage; tippler station; FMEA; fishbone diagram; critical component
