Abstract

This research aims to provide a detailed guideline for the replacement process of superheater tubes in the Takuma Boiler N-900 R. The superheater tube is a critical component in a boiler that increases the temperature of the steam exiting the boiler to achieve higher temperatures. Superheaters have been utilized since the early 20th century, coinciding with the initial use of steam engines. The research employed direct observation to analyze the causes of failure in the superheater tubes. The primary objective is to present the necessary processes and steps for replacing superheater tubes. The findings indicate that the primary cause of failure in the superheater tubes is overheating, necessitating their replacement. The replacement process involves several stages, including disassembling old superheater tubes, installing new ones, and testing hydrostatic and steam. The results of this replacement process show improved efficiency in the superheater and prevention of further failures in the superheater tubes.

Abstract

This study aims to design and implement a shallot slicing machine with a 50 kg/hour capacity to improve production efficiency among food-sector MSMEs. The machine features an elbow-iron frame, a 0.5 HP electric motor, and a pulley-V belt transmission system driving stainless steel blades. Performance testing evaluated actual capacity, transmission stability, and slice uniformity. Results show the machine operates stably with near-target capacity and produces relatively consistent slices. The estimated cost of IDR 6,700,000 is economical for small businesses. The design’s strength lies in its simplicity, hygienic materials, and affordability. This machine is expected to offer an appropriate technological solution to enhance productivity and product quality in shallot processing.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) in the food sector still face obstacles at the stage of drying potato oil. This process reduces quality, accelerates cooling, and reduces product shelf life. This research designed a simple centrifugal force-based oil slicing machine with food-grade material that is safe to use. Tests showed the machine was able to lower the oil content by up to 28% in a duration of 60 seconds per cycle, with an adequate capacity of five kilograms of fries. This innovation improves production efficiency, quality, and competitiveness of MSMEs in the processed food industry.

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 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

The increase in the volume of plastic waste in Indonesia, which reaches approximately 64 million metric tons per year, coupled with a still-low recycling rate, underscores the need to repurpose High-Density Polyethylene (HDPE) plastic waste into products with both practical and economic value. This study aims to design and fabricate a laboratory-scale hexagonal injection molding die as part of an effort to convert recycled HDPE plastic waste into decorative products, as well as to analyze the molding process and evaluate the quality of the resulting products based on their shape, dimensions, and surface condition. The research methodology involved several stages concept selection using the Pugh method, detailed product design, determination of the planning basis and selection of machine components, structural strength analysis of the mold, and the fabrication and testing of the mold on an injection molding machine. The results of the study show that the mold design developed using low-carbon steel with three cavities is capable of producing hexagonal products in accordance with the design dimensions, namely a hexagonal size of 50.00 mm with a mold depth of 5 mm, as well as a material capacity of 29.24 grams for the three cavities. The molded products demonstrated geometric conformity with the initial design, although the surface quality still showed a level of smoothness that was not entirely uniform and has the potential for further improvement through process parameter optimization in future research. This study is expected to serve as a reference in the development of laboratory-scale injection molding designs and to support efforts to manage HDPE plastic waste into products with both practical and economic value.
