Abstract

One of the main issues with high-speed plastic cutting machines is the generation of static electricity due to friction between the plastic film and machine components during the production process. This study aims to analyze the impact of static electricity on production losses and operational costs in Cut-to-Length Rotary plastic cutting machines at PT Elsida Karya. The study focuses on the influence of static electricity on machine performance, production stability, and industrial operational efficiency. Previous studies have generally addressed product quality and machine maintenance, while research examining the relationship between static electricity and production losses and operational costs remains limited. The study employs a quantitative descriptive approach with a case study design. Data was collected through direct observation, interviews, production documentation, and analysis of operational data. The results indicate that static electricity causes plastic to adhere to the cutting blades, resulting in machine downtime of 15–40 minutes per shift and reducing production output from 3,000 pieces/hour to approximately 2,600–2,700 pieces/hour. Productivity decreased by approximately 10–13%, with estimated production losses reaching Rp9,000,000–Rp12,000,000 per month. The implementation of an anti-static system—including ionizers, optimized grounding, and anti-static brushes—is expected to improve production efficiency by 8–12%. Thus, a static electricity mitigation system is a critical solution for enhancing production stability and reducing operational losses in the plastics industry.

Abstract

Tobacco farmers in Gulang Village, Kudus Regency, face post-harvest challenges, particularly in the drying process, which is still conducted conventionally, resulting in prolonged drying time, high energy consumption, and inconsistent product quality. This community service program aimed to improve drying efficiency and tobacco quality through the implementation of a heat exchanger-based tobacco drying machine. The dryer was designed with dimensions of 1.2 m × 2.4 m × 1.2 m and equipped with 16 trays, utilizing an indirect heating system to ensure stable temperature control and prevent smoke contamination. The implementation stages included needs assessment, machine design and manufacturing, program socialization, operational and maintenance training, field implementation, and before–after performance evaluation. The results showed a reduction in drying time from 72.0 hours to 52.2 hours (27.5% efficiency improvement), energy savings from 100.0 to 75.6 kWh equivalent (24.4% reduction), and an increase in dried tobacco output from 84.6 kg to 93.6 kg per cycle (10.6% improvement). The final moisture content was more uniform at 13–14%. Statistical analysis indicated significant differences between conventional and machine-based drying methods (p < 0.05). The implementation of this appropriate technology effectively enhanced post-harvest efficiency, improved product quality, and supported the sustainability of smallholder tobacco farming in Gulang Village.

Abstract

Rustic wood refers to a type of wood that has a rough, natural appearance, and often retains the original characteristics of the wood. The term "rustic" describes a style or appearance that is simple, old-fashioned, and rustic in nature. Rustic wood is often used in interior and exterior design to create a warm, natural atmosphere. The research methodology was carried out by searching for literature studies collected from journals, papers and the internet. Conduct interviews with supervisors and PT employees. Rajawali Perkasa Furniture in the field. As well as direct observations in the field to find solutions related to problems that occur to take corrective solutions in accordance with company procedures. The maintenance carried out to repair Rustic machines is Preventive Maintenance. A maintenance system that is carried out regularly to ensure the condition of the machine and extend the life of the machine. Preventive maintenance is carried out regularly to prevent damage to the equipment so that if minor damage is found it can be repaired immediately. With planned maintenance, PT Rajawali Perkasa Furniture aims to find symptoms of damage to equipment before it experiences fatal damage, keep its production equipment machines in optimal condition, reduce the risk of damage, and increase overall productivity.
