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 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.

Abstract

Sludge generated from the wastewater treatment plant of palm oil mills contains a very high moisture content, which increases volume, handling costs, and poses a potential risk of environmental pollution if not properly managed. One of the main challenges encountered is the lack of a simple, economical small-scale dewatering machine that is suitable for the characteristics of sludge produced by palm oil mill wastewater treatment systems. This study aims to design and fabricate a dewatering machine to separate sludge from water in the wastewater treatment ponds of a palm oil mill. The research method involved designing the machine using SOLIDWORKS software, performing technical calculations of the main components such as motor power, shaft dimensions, belt transmission, and bearings, followed by fabrication and assembly processes. The performance of the machine was then evaluated based on its ability to separate sludge and water. The results indicate that the designed dewatering machine has a capacity of 200 litres per hour with a motor power of 1 HP; however, its performance has not yet reached optimal conditions, as part of the sludge remains attached to the screen, thereby increasing the motor load and hindering the movement of the screw. The findings of this study suggest that the dewatering machine design has the potential for further development through optimisation of the screw geometry and filtration system in order to improve sludge water separation efficiency in palm oil mill wastewater treatment plants.

Abstract

This research discusses the design and testing of a simple, economical pyrolysis device for converting plastic waste into an alternative fuel. The pyrolysis device measures 1000 mm × 700 mm × 580 mm, with a reactor constructed from a used 12-kg LPG cylinder, equipped with a steam delivery pipe, a two-coil spiral condenser, and other supporting components. Test results indicate a device performance of 0.000005 liters/h, indicating that the device is still operating on a small scale with low efficiency. The volume of liquid smoke produced reaches 3.26 m³/kg based on the assumed water vapor density. Recommendations for development include optimizing the condenser design, adding thermal insulation, using more comprehensive measuring instruments, and testing various temperatures and plastic types to improve efficiency. This research is the first step toward using plastic waste to produce valuable alternative fuels.

Abstract

Low wind speeds in residential areas often pose an obstacle to the use of small- and micro-scale wind turbines. Various efforts have been made to address this issue, particularly to improve wind turbine performance. One such method is the application of a diffuser, or wind lens, during turbine operation. However, existing diffuser designs still require further development in order to achieve more efficient aerodynamic performance, optimize wind speed, and provide a more compact configuration. In this study, a diffuser with curved geometry based on the Wortmann FX-63-137 airfoil was analyzed using Ansys Fluent simulations. The variations tested included angles of attack of 0°, 4°, 8°, and 12°, as well as flange heights of 0.05D, 0.10D, 0.15D, 0.20D, and 0.25D. The simulation results indicated an increase in wind velocity at the throat area, with the best performance achieved at a 4° angle of attack with a 0.10D flange. Under these conditions, the available wind power reached 203.20 W, representing an increase of approximately 34.01%.
