Abstract

Stroke is one of the leading causes of disability in Indonesia, often affecting motor functions, particularly in the hands. Rehabilitation plays a crucial role in restoring these functions. This study aims to design and develop a hand training device for stroke patients using 3D printing technology and a soft pneumatic actuator system. The process began with CAD-based design, followed by fabrication using Fused Deposition Modeling (FDM) 3D printing with TPU material, and final assembly of all components. Testing results showed that the device could effectively perform finger flexion movements at air pressures ranging from 0.49 MPa, and was capable of gripping objects such as a spiked ball. This device offers an affordable, customizable, and flexible rehabilitation solution to assist stroke patients in regaining hand motor function.

Abstract

Waterjet propulsion systems manufactured by Additive Manufacturing (AM) offer potential advantages for lightweight marine applications, but experimental data on the static thrust performance of polymer-based waterjet thrusters remain limited. This study presents an experimental investigation of the static thrust performance of a waterjet thruster fabricated from Thermoplastic Polyurethane (TPU 95A) using Fused Filament Fabrication (FFF). Static thrust was measured at rotational speeds of 1500, 3000, 4500, 6000, 7500, and 9000 rpm using a 13 hp internal combustion engine. The results showed a consistent increase in static thrust with rotational speed, from 20 N at 1500 rpm to a maximum of 170 N at 9000 rpm. However, the increase in thrust became less proportional at higher rotational speeds, indicating increasing hydraulic and mechanical losses. These losses may be associated with flow separation, turbulence, tip leakage, and elastic deformation of the TPU impeller under hydrodynamic and centrifugal loading. Despite this behavior, there is not any abrupt thrust fluctuations were observed throughout the tested operating range, indicating stable static thrust generation. The maximum thrust of 170 N demonstrates the capability of the FDM-printed TPU 95A thruster to generate measurable propulsion force under static conditions. The results provide experimental reference data for the development and optimization of additively manufactured waterjet thrusters for small-scale marine propulsion applications.

Abstract

The Aciera F3 milling machine is a vital tool in practical and production activities at the Mechanical Engineering Laboratory of the Bangka Belitung State Manufacturing Polytechnic. Damage to the electrical system resulted in the machine being unusable, which hampered the learning process. This study aims to identify the source of the damage and determine the appropriate repair method. The strategy implemented is Root Cause Analysis (RCA) with the 5 Whys method. Data were collected from interviews with technicians, literature studies, maintenance and repair records, and manuals. The research findings indicate damage to the vulnerable auxiliary contactor and broken terminals, resulting in a power outage to the control panel. The 5 Whys analysis indicates that the old component life and lack of regular replacement are suspected to be the main causes of the auxiliary contactor damage.

Abstract

Sistem propulsi waterjet sering dipilih dalam menggantikan baling-baling konvensional untuk kapal yang membutuhkan kecepatan tinggi, draf dangkal, daya propulsi terlindungi, kemampuan manuver tinggi di semua kecepatan, kebisingan rendah dalam aplikasi militer, dan getaran rendah. Cara kerja dari waterjet thruster ialah menggerakkan kapal dengan mengeluarkan tekanan pada fluida yang dihasilkan dari bantuan propeller sehingga kapal dapat bergerak, dan arah aliran air akan menuju ke belakang namun pergerakan kapal menuju ke depan. Penelitian ini bertujuan untuk mendapatkan hasil yang paling berpengaruh dari variasi jumlah blade inlet turbo yaitu 11, 12, 13, 14,  dan 15 blade inlet turbo  terhadap gaya dorong tertinggi pada sebuah prototype waterjet thruster. Penelitian ini menggunakan filament ST PLA (Super Tough Poly Lactic Acid) sebagai material part 3D printing pada komponen waterjet thruster. Metode penelitian yang digunakan adalah rancangan waterjet thruster menggunakan konsep mesin tempel. Hasil penelitian ini menunjukkan bahwa gaya dorong terendah  mencapai 0.71 N pada variasi jumlah blade inlet turbo 11, sedangkan untuk gaya dorong tertinggi mencapai 1.79 N pada variasi jumlah blade inlet turbo 14.

Abstract

Waterjet propulsion is a propulsion system used on various water transportation, such as speedboats and amphibious vehicles. This technology works by drawing water through an inlet at the bottom of the vessel and then expelling it at high speed through a nozzle to generate thrust. Water vehicles that use Waterjet Propulsion such as Jet Skis, use waterjets for faster and more agile maneuvering movements, fast patrol boats used by the military and police for fast operations in shallow and narrow waters, fast ferries use this technology for fuel efficiency and high speed, amphibious assault ships used by the military to land troops and heavy vehicles on the beach, fast cruise ships use waterjets because they have minimal vibration and are smoother compared to conventional propellers. The advantages of waterjet propulsion compared to conventional propellers are its ability to operate in shallow waters, better maneuverability, high speeds with better efficiency. Based on these advantages, this research aims to design an innovative twin waterjet propulsion system. Where the waterjet propulsion is equipped with an inlet section that functions to increase thrust. The main components, which include the outlet, inlet, and impeller, are made using 3D printing technology with Ethylene Propylene Acrylate Polylactic Acid Carbon Fiber (EPA PLA CF) material. Tests were conducted to investigate the performance of waterjet propulsion on a laboratory scale using an electric motor at three rotational speeds: 2,500 rpm, 3,500 rpm, and 5,000 rpm. The test results showed a linear increase in thrust, with values ??of 3 N at 2,500 rpm, 6 N at 3,500 rpm, and 9 N at 5,000 rpm.

Abstract

Indonesia, as an archipelagic country, has great potential in developing efficient maritime propulsion systems. One alternative technology being explored is the waterjet thruster, a ship propulsion system that operates based on the principle of accelerating fluid flow through an impeller and nozzle. This study aims to examine the effect of nozzle size variation on the thrust produced by a waterjet thruster prototype fabricated using 3D printing technology with Thermoplastic Polyurethane (TPU) material. Two nozzle types were used: Type 1 (2-inch diameter) and Type 2 (2 × 1½-inch diameter). An experimental method was employed by measuring thrust under full and half throttle conditions using a dedicated thrust measuring device. The results show that Type 2 nozzle produced the highest thrust of 45.3222 N, while Type 1 produced only 40.46625 N. The 12% increase in thrust observed in Type 2 indicates that a nozzle design with a smaller cross-sectional area can optimize fluid flow efficiency and system performance. This study concludes that nozzle dimension significantly influences thrust efficiency, and a well-designed nozzle can offer an efficient and environmentally friendly propulsion solution for small vessels.

Abstract

A waterjet thruster is a ship propulsion system that operates by ejecting high-speed water through a nozzle to generate thrust. The system consists of main components such as the inlet turbo, impeller, and outlet turbo, all designed to maximize thrust efficiency. This study aims to evaluate the thrust performance of a waterjet thruster made from stainless steel 304 (SS304) through experimental testing by comparing the same object using different testing methods, namely variations in impeller rotational speed. The waterjet thruster consists of a 3-blade impeller, a 12-blade inlet turbo, and a 12-blade outlet turbo, manufactured through turning, welding, and assembly processes. The tests were carried out under two different operating conditions—1000 rpm and 1800 rpm—to assess the effect of different testing methods on thrust performance. The results show that increasing the rotational speed significantly increases the generated thrust. At 1000 rpm, the average thrust reached 74.163 N, while at 1800 rpm it increased to 122.919 N. This confirms that the system’s performance improves when the same object is tested under different operational methods, in this case a higher impeller rotation. SS304 material proved capable of maintaining its performance and is suitable for waterjet thruster components due to its mechanical properties and corrosion resistance
