Mario Andreas — 2023-10-15

Ship Movement is an important factor in shipbuilding. In determining the ship's maneuverability, there are many aspects that must be considered in the design, namely resistance and angle of attack of the waves. In determining the angle of attack of the waves, the test uses the trigonometry principle to determine the angle of attack of the waves. Where the results of the 3 maneuvers of the Heave, Roll and Pitch ships at speeds of 0 knots, 0.389 knots, 0.778 knots, 1.166 knots, 1943 knots, it is known that the displacement model ship can be used in an open area with a set scale.

Perancangan Gearbox Transmisi untuk Amphibious Articulated All Terrain Vehicle

Firhan Surya Herlambang — 2023-10-15

Indonesia is one of the countries with a high level of natural disaster vulnerability, so a good disaster mitigation process is needed. Amphibious Articulated All Terrain Vehicle (AAATV) is designed as one of the solutions to the difficulty of the mitigation process. Amphibious Articulated All Terrain Vehicle is a vehicle with special capabilities that are able to pass through various terrains. Amphibious Articulated All Terrain Vehicle consists of several systems, one of which is the propulsion system. In the Amphibious Articulated All Terrain Vehicle drive system, there is one sub-system, namely the transmission gearbox. This design process uses the VDI 2222 methodology. The design and validation process uses SOLIDWORKS and KISSsoft software. From the design results, it is found that the vehicle will use a Kubota V2203 type diesel engine with a power of 36.4 kW. The desired speed variation is achieved with values of 9.85 km/h, 19.34 km/h, 39.64 km/h, and 10.04 km/h. The design weight is 58.73 kg with dimensions of 346.1 mm x 260 x 347 mm

Waste is a real problem and will continue to increase as the human population grows. The increase in waste will have a negative impact on the environment and health if not managed properly. The process of handling household waste is still limited to collection and disposal carried out by the local Sanitation Service. In this case, recycling household waste is needed to reduce environmental impacts and improve economic and social welfare in the community. However, the problem that is often faced for this recycling process is the initial processing which includes sorting and crushing waste. This research aims to produce an efficient and appropriate household waste sorting machine design, this waste sorting machine design is useful for separating household waste that is organic and inorganic.

Teaching aids are used in the field of education to streamline the implementation of the learning process. In this research, AC servo motor learning media with type R88M-1M10030-S2. The learning media will focus on controlling the position and speed of the servo motor for the x, y and z axes. This research uses the experimental work method. Testing of this research is carried out in Motion Variety parameter testing, NC function testing, HMI function testing, and user evaluation testing. It was found that the percentage of deviation value was 4.9%. In position testing, the deviation value of the X and Z axes has a small average final error with an X-axis error value of 0.21% and a Z-axis of 0.24%. It can be seen that the average Y-axis error is the largest with an average error value of 5.84%. Overall the average value of the HMI evaluation is 89% for the quality of the AC Servo Motor Teaching Aid HMI that has been made. This figure is classified as very good to continue using the tool as an auxiliary medium for the teaching process.

Perancangan Ulang dan Analisa Mesin Benchtop Injection Molding dengan Metode VDI 2222

Injection molding is a process by which plastic is heated until it softens to fill a closed mold and form a product. One of them is the benchtop injection molder, where the machine that was previously made at POLMAN had problems, namely the main frame structure and injection mechanism which was less sturdy during the injection process and the heating system which overheated. Based on these problems, a redesign and analysis was carried out on the existing benchtop injection molder machine. The design methodology used is VDI 2222, which is a technical concept design methodology suitable for product development. Heat Transfer Simulation on existing and latest designs using COMSOL Software with geometry, material, temperature, fluid inlet and outlet, and mesh parameters. The results obtained were uneven heat distribution to the middle of the existing barrel at a temperature of 4600K, while the new barrel had an even heat distribution to the middle at 4730K at the 10th second. The latest machine weighs 17.78 kg, dimensions 775 x 266 x 426 mm, barrel capacity 19 grams with an aluminum frame and tight band heater installation.
