Abstract

General Background: Banana processing is an important agro-industrial activity in Indonesia, particularly for producing banana chips with consistent quality. Specific Background: Conventional manual slicing methods are inefficient and result in inconsistent thickness, limiting productivity and product quality. Knowledge Gap: Previous approaches have not fully integrated manufacturing process analysis with time, cost, and performance evaluation in a single machine design. Aims: This study aims to analyze the manufacturing process of a banana slicer machine with a capacity of 59 kg/hour, including time estimation, cost calculation, and performance testing. Results: The manufacturing process consists of cutting, drilling, welding, turning, and milling, resulting in a total production time of 29.63 hours and a total cost of Rp 5,058,262. Performance testing shows that the use of three blades produces the most consistent slice thickness of 2 mm with good quality output. Novelty: The study integrates detailed manufacturing time analysis, cost estimation, and performance evaluation within a single machine development framework. Implications: The findings provide practical guidance for improving production efficiency and product quality in small to medium-scale banana processing industries. Keywords: Banana Slicer, Manufacturing Process, Production Cost, Machine Performance, Agro-Industry Key Findings Highlights Total fabrication duration reached 29.63 hours with structured process stages Optimal blade configuration identified for uniform slice thickness Economic calculation established selling value with defined profit margin

Abstract

General Background: The increasing use of petroleum-fueled transportation has intensified concerns regarding air pollution and the need for alternative energy-based mobility systems. Specific Background: Electric bicycles represent a practical short-distance transportation option, and battery performance becomes a critical factor in determining their operational capability. Knowledge Gap: Although electric bicycles are increasingly discussed, limited experimental studies directly compare dry batteries and wet batteries under different load and travel-distance conditions in simple electric bicycle modifications. Aims: This study aims to evaluate the power consumption characteristics of a modified electric bicycle by varying load and travel distance using dry and wet batteries. Results: Experimental testing was conducted using 50 kg and 60 kg loads over distances of 200 m, 300 m, and 400 m. The findings show that greater load and longer travel distance increased battery power consumption. For the dry battery, the lowest power consumption was 0.24 V at 50 kg and 200 m, while the highest was 0.97 V at 60 kg and 400 m. For the wet battery, the lowest value was 0.37 V at 50 kg and 200 m, while the highest reached 1.12 V at 60 kg and 400 m. Novelty: The study provides direct comparative experimental evidence of discharge behavior between dry and wet batteries in a simple modified electric bicycle under controlled load-distance variations. Implications: These findings contribute useful engineering insight for selecting battery types and operating conditions in small-scale electric bicycle development. Keywords: Electric Bicycle, Battery Performance, Power Consumption, Load Variation, Travel Distance Key Findings Highlights Higher load consistently increased electrical energy usage during operation. Longer travel routes produced greater voltage reduction in both battery types. Wet-cell storage showed the largest discharge under the heaviest testing condition.
