Abstract

Chopper motorcycle frames had a fierce and macho impression on users. The frame was characterized by high handlebars, long front legs and a low seat. Chopper motorcycles were suitable for casual riding. Therefore, the Chopper frame must be specially designed or custom-made. Making the frame required a jig to maintain precision and dimensional accuracy in accordance with the original frame. Making a universal jig allowed craftsmen to make Chopper frames according to market demand without leaving the center balance on the frame. The jig manufacturing process included material selection, measurement, material cutting, machining, jig calibration, jig assembly, welding, checking and finishing. The welding process used argon TIG welding. The use of the jig shortened the frame manufacturing time by 2 times faster and minimizes wasted frame material due to dimensional errors.

Abstract

Perubahan cuaca ekstrem yang menyebabkan kekurangan air pada musim kemarau dan banjir pada musim hujan telah menjadi masalah lingkungan yang signifikan. Selain itu, rendahnya kemampuan tanah, terutama di kawasan perumahan dan gedung perkantoran, dalam meresap air hujan semakin memperburuk keadaan. Salah satu solusi untuk mengatasi masalah ini adalah pembangunan sumur resapan, yang berfungsi menampung air hujan dan memungkinkan air meresap ke dalam tanah. Penelitian ini bertujuan untuk mengatasi masalah banjir dan meningkatkan daya serap air ke dalam tanah melalui pembuatan sumur resapan di wilayah Salatiga. Metode pelaksanaan meliputi pembuatan sumur resapan dengan berbagai konstruksi, seperti sumur tanpa pasangan di dinding, sumur dengan batu bata atau batu kali, serta sumur dengan dinding besi beton atau blawong, yang disesuaikan dengan kondisi tanah. Hasil dari program ini menunjukkan bahwa sumur resapan efektif mengurangi aliran permukaan, mengatasi banjir, mengisi ulang cadangan air tanah, serta mencegah erosi dan pencemaran air tanah. Selain itu, sumur resapan juga dapat mengurangi beban pada sistem drainase kota. Kesimpulannya, pembangunan sumur resapan merupakan solusi yang efektif dalam pengelolaan air hujan, yang dapat mengurangi dampak banjir, meningkatkan kualitas air tanah, serta menjaga keseimbangan ekosistem di wilayah perkotaan.

Abstract

Pump units with a Caterpillar C27 engine with an EUI (Electronic Unit Injector) fuel system that often has low power due to filter clogging at PT. Sapta Indra Sejati. Filter cloggingoccurs due to due to the thickened biofuel content and creates a crust. If the machine has a problem, the mining process can be disrupted because the coal loading area is flooded. This study aims to create an additional system in the form of a automatic semi-returnless where the fuel return line is changed automatically into the filter because the fuel return is clean. The movement of the return control valve is regulated by a microcontroller which is programmed according to specifications and needs. The microcontroller used is Arduino Unowith pressure and temperature sensors. Arduino Uno is programmed when the engine will experience low power with a fuel pressure of 400 kPa then the return path is changed to semi returnless. With a change in the semi returnless path, the pressure becomes stable at 380 kPa and the engine RPM is stable with power that is still maintained. The advantages of semi-returnless system are that filter replacement costs can be reduced and production time is not interrupted.

Abstract

The challenge of a CNC Router is the dust and small particles produced during the cutting process such as wood, aluminum or acrylic materials. These small particles can disturb the health of operators. 3D printing is a technology where materials are arranged layer by layer to produce three-dimensional products. PETG filament is a type of polymer that has a density of 1.38 g/cm3 and has the advantage of being weather resistant, not being damaged or losing color when exposed to UV light. PETG filament uses a printing temperature of 230°C-265°C. This bracket is designed to hold hoses and dust collector. The Bracket design can be installed on a CNC router machine without interrupting the cutting process or reducing the quality of the final result. The method used is Autodesk Inventor Professional 2023 student edition software for 3D design and UltiMaker Cura for the slicing process. This research resulted in a bracket design and prototype using a 3D printer. The bracket exhibits sufficient structural capability to hold the cooling hose and dust collector. There is a dimensional difference between the design measurements and the workpiece that has been made of 0.27 mm in the CNC Router head diameter and 0.1 mm in the hose diameter. This is due to the work tolerances and parameters used on the 3D printer machine. By implementing the Hose and Dust Collector Bracket, it is hoped that small particles can be reduced so that a clean and dust-free work environment can improve operator health and comfort.

Abstract

The increasing demand for efficient and precise manufacturing processes in the automotive industry has led to the development of automated assembly systems, including pneumatic-based tools. This study focuses on the design, development, and evaluation of a pneumatic Bush installation tool for motorcycle engine mounting production efficiency. The tool was tested against manual methods (hammer and jack) to compare installation time, accuracy, and defect rates (NG). A quasi-experimental approach was used, involving trial and error testing, prototype validation, and comparative analysis. The results showed that the pneumatic system significantly outperformed the manual method, with an 80% improvement in efficiency—reducing installation time from 120 seconds (manual) to 45 seconds (pneumatic). Additionally, Bush misalignment was reduced from 40% (manual) to 10% (pneumatic), while installation-induced defects dropped from 35% to only 5%. The findings demonstrate that the pneumatic-assisted tool provides more consistent pressure control, improved accuracy, and reduced error rates, making it a superior alternative to manual methods. This study contributes to the advancement of automated assembly technologies in the motorcycle manufacturing industry.
