Abstract

This article analyzes the durability of electrical energy in palm fruit cutter machines as an efficient and environmentally friendly innovation in the field of harvesting tools. The machine is designed using a 12V 15A DC motor that converts the rotary motion into translation through a crank slide mechanism, powered by a 35Ah battery. Tests were carried out on oil palm trees 3–5 meters high by monitoring power consumption and operating time. The results show that cutting thick fronds requires 15 Watts/minute, while thin ones require 11.25 Watts/minute. The effective operation duration reaches 1 hour and 52 minutes. Performance factors are influenced by battery condition, cutting load, transmission efficiency, and cutting tool design.

Abstract

The small-scale food industry faces challenges at the drying stage of potato chips that affect product quality, texture, and shelf life. This research designed and tested a centrifugal force-based slicing machine with a capacity of 20 kg per cycle. The design method is carried out through an engineering approach that includes literature studies, AutoCAD design, prototype fabrication, and performance testing. The engine uses a 1 HP electric motor, a V-belt transmission system, and perforated stainless steel tubes. The test results showed that the engine was able to significantly lower the oil content in just ±30 seconds per cycle. This design is considered appropriate to increase production efficiency and competitiveness of MSME products.

Abstract

This study aims to analyze the effect of borax as a flux on the melting performance of recycled 3004 aluminum from beverage can waste. The melting process was carried out using an oil-fueled furnace with six borax variations, ranging from 2.5 g to 15 g for 500 g of recycled aluminum. The results showed that the net aluminum mass increased from 209 g to 293 g, while the slag mass decreased from 242 g to 139 g. Linear regression analysis revealed a positive correlation between borax and net mass (R² = 0.9116) and a negative correlation between borax and slag (R² = 0.9135). Therefore, borax proved effective in increasing the yield of clean metal and reducing slag during the recycling of aluminum.

Abstract

The increasing volume of composite plastic waste poses serious challenges to the environment, so practical and sustainable treatment solutions are needed. This research aims to design a composite plastic shredding machine with a capacity of 10 kg/h, suitable for small industries and households. The design method employed a quantitative approach, incorporating frame analysis, a V-belt transmission system, and the selection of a carbon steel blade. The results show that the machine can achieve the target capacity with low energy consumption and good structural stability. The study's conclusion confirms that this machine has the potential to be an effective solution in supporting sustainable plastic recycling programs on a local scale.

Abstract

The problem of plastic waste continues to increase and requires effective technical solutions through the recycling process. One of the crucial stages is enumeration, which aims to reduce the size of the material so that it can be easily reprocessed. This research aimed to design a plastic and composite polymer shredding machine with a capacity of 10 kg/h, featuring a simple construction, energy-saving capabilities, and suitability for both household and small industrial applications. The design process includes power requirement analysis, frame design, blade selection, and transmission system. The test results showed that the machine was able to produce plastic shreds of an average size of 5 mm with performance close to the target capacity. This machine has the potential to improve the treatment of plastic waste locally.

Abstract

This study aims to design a composite polymer shredding machine with a capacity of 50 kg/h to enhance recycling efficiency. The machine is powered by a 3 HP electric motor, equipped with a 1:50 ratio reducer and 200 mm diameter blades. Technical analysis encompasses calculations of cutting force, torque, and throughput, supported by CAD/CAE modeling to validate the structural design. The results show a shredding capacity of 833.33 g/min, cutting force of 47.088 N, and torque of 9.4176 Nm. The machine features a compact, energy-efficient design and delivers consistent output. A UNP steel frame ensures structural stability against dynamic loads. With good efficiency and sustainability, this design is suitable for small to medium-scale industries involved in composite polymer material processing.

Abstract

This study aims to analyze the performance of oil slicing machines on potato chip products that are specifically designed for the needs of small-scale food industries. The machine has a capacity of 10 kg and is operated for 3 minutes per cycle. The test was conducted five times on potato chip samples, with the primary parameters being the weight before and after the slicing process. The average weight of chips before draining is 568 grams, while after draining, it decreases to 529 grams, indicating a 39-gram decrease in mass, which corresponds to a reduction in oil content. The calculation of the thinning efficiency revealed that the engine was capable of reducing the oil content by up to 6.87% of the initial weight. The engine is driven by an electric motor with a rotation of 1380 rpm, transmitted through a pulley system (3 inches: 13 inches), resulting in a tube rotation of 330.5 rpm. These results demonstrate that the slicing machine effectively reduces the oil content of potato chips in a short time, making it suitable for micro and small businesses in the snack sector due to its simplicity, energy efficiency, and cost-effectiveness.

Abstract

Polymers are the result of monomer polymerization with a lower density than metals but a much smaller elastic modulus, making them less rigid and strongly affected by temperature. This study evaluates the performance of a laboratory-scale crushing machine for polypropylene blended with activated carbon at varying compositions. The machine employed carbon steel rotary blades driven by a 1 HP electric motor through a gearbox transmission. Results showed average crushing times of 3.5–4 minutes/kg. Pure polypropylene produced a 72% fine fraction, while adding 10% activated carbon reduced it to 65%. Crushing efficiency remained above 85%, demonstrating stable performance and feasibility for composite material applications.
