Abstract

The piano manufacturing industry comprises multiple stages to achieve a high-quality product, one of which is the surface finishing of the cabinet after sealer coating. In many woodworking industries, this finishing process is still performed manually using scotch-brite, which requires significant labor and extended processing time. To enhance efficiency, the design and performance evaluation of a scotch-brite machine, manually operated by an operator, were conducted. The objective of this study is to assess the machine’s performance and compare its efficiency with conventional manual finishing. Experimental tests were carried out using ten board samples coated with basecoat or sealer. Each sample was subjected to ten sanding cycles at inverter frequency variations of 30 Hz, 35 Hz, 40 Hz, 45 Hz, and 50 Hz. The initial gloss level of the samples was 18 GU, while the finishing standard ranged between 10–14 GU. The optimal result was obtained at 50 Hz, producing an average gloss of 12.4 GU. The sanding process for ten samples required 223 seconds, equivalent to 3.7 minutes. The scotch-brite machine demonstrated higher efficiency, achieving an efficiency level of 53.5%, reducing processing time by approximately 4.2 minutes compared to the manual method, and lowering operator workload. These findings indicate that the machine can effectively support improved quality, consistency, and productivity in the piano manufacturing industry.

Abstract

Agriculture is the primary livelihood for most of Indonesia's population, which has vast agricultural land. However, there remains a dependency on chemical fertilizers, which degrade soil quality compared to organic farming that can optimize plant health and productivity. The energy needs in the agricultural sector, including mechanization and fertilizer production, are critical but still heavily reliant on fossil fuels. It is, therefore, essential to reduce this dependency by utilizing environmentally friendly alternative energy sources. This study examines the use of solar energy to power machines in the process of producing organic fertilizer. The tools used in the study include a 100 Wp solar panel, solar energy conversion components, a 12 Volt 33 Ah battery, a ¼ Hp electric motor, a voltage and current meter, a temperature gauge, a sunlight intensity meter, and an organic fertilizer processing machine. The research method analyzes several variables, including sunlight intensity, power, voltage, current, charging time, and battery usage. The study found that the solar panel used was insufficient to power the ¼ HP motor, requiring the addition of three more solar panels and batteries to meet the motor's power requirement of 233 watts. Battery charging tests required 3 hours, and battery usage for machine operation without solar panel installation lasted 1 hour and 40 minutes, while battery usage for machine operation with solar panel installation lasted 6-7 hours. Keywords: Environmentally friendly energy, Fertilizer crushing machine, Organic fertilizer, Solar energy.
