Abstract

The pineapple juice extractor machine is used for the process of pressing pineapples to produce juice while separating the pulp. The currently available machines generally use electric motors with a power of 0.35 HP. However, with that motor power, the existing machines are not able to press pineapples optimally, as the electric motor tends to lose power during operation. Therefore, this research focuses on calculating the appropriate motor power to be used in a pineapple juice extractor machine with a capacity of 5 kg/hour. The method applied involves calculating several parameters, including load, capacity, torque, and motor power. This is intended to ensure that the motor used is truly capable of accommodating the desired machine capacity. Based on the calculations performed, the most suitable electric motor for a pineapple juice extractor machine with a 5 kg/hour capacity is one witch a power rating of 0.5 HP.

Abstract

Industrial crate washing is a crucial activity in maintaining hygiene and operational efficiency within the manufacturing sector. PT. Berdikari Metal Engineering faces challenges due to a manual washing process that is labor-intensive, time-consuming, and only capable of cleaning 25 crates per day out of a 150-crate target. This study aims to design an automatic crate washing machine with a focus on high-pressure washing systems to enhance process effectiveness. The design method follows the VDI 2222 approach, consisting of planning, conceptualization, design, and simulation stages. The machine features three main zones: washing, rinsing, and drying, where washing and rinsing utilize a jet pump system. Technical calculations determined that the required motor pump power for the washing zone is 10 HP, based on the number of nozzles, flow rate, and spray pressure of 80 psi. Simulation results using SolidWorks indicate that the machine structure is safe, with stress and safety factor values within acceptable limits. In conclusion, the design successfully delivers an efficient washing system that meets the company's daily production targets and reduces reliance on manual labor.

Abstract

Qibla direction guide stick specially designed for blind people. This stick is equipped with HC SR04 Ultrasonic Sensor to detect surrounding objects, HMC5883L Compass Sensor to determine the Qibla direction, and a control system that uses Arduino Uno as the programming brain. The development method involves the design and integration stages of these sensors, as well as the development to process sensor data to produce qibla direction information. The results show that this qibla direction guide stick can be used effectively, providing timely and accurate feedback to the user. Thus, the development of this technology has great potential to improve the independence and quality of life of blind people in their religious practices. This study makes an important contribution in the field of technology expanding the possibilities for blind people to participate fully in religious activities.

Abstract

Briket arang merupakan salah satu batangan arang yang terbuat dari bahan baku tempurung kelapa dan dicetak menggunakan Mesin agar menghasilkan kalor yang sangat tinggi dan bisa menyala bertahan lama. Penggunaan briket arang dari tempurung kelapa akan memberikan kontribusi pada pengurangan ketergantungan terhadap kayu bakar, gas elpiji dan minyak tanah yang ketersediaannya semakin menipis dan tidak dapat diperbaharui khususnya bagi masyarakat dibeberapa daerah sungailiat dan pada saat yang bersamaan dapat mendukung pemanfaatan sampah tempurung kelapa sebagai salah satu bahan bakar.Penelitian ini bertujuan untuk merancang dan membangun Mesin Pencetak Briket Arang Tempurung Kelapa berkapasitas 12kg/jam dan merancang sistem perawatan pada Mesin Pencetak Briket Arang Tempurung Kelapa agar Siap digunakan dan memperpanjang usia pakai. Metode perancangan yang digunakan dalam penelitian ini adalah Verein Deutsche Ingenieuer (VDI 2222). Hasil penelitian pada Mesin Pencetak Briket Arang Kelapa dengan menggunakan metode rancangan VDI 2222 yaitu mencetak Briket Arang Kelapa dengan panjang 60cm dan mempunyai kapasitas 12kg/jam. Sistem perawatan pada mesin ini menggunakan perawatan terencana dan pemeriksaan bagi operator untuk melakukan perawatan mandiri.

Abstract

Shaft is one of the materials that must have a low surface roughness value from the machining process, especially using the Tornos Geminis S.L semi-automatic lathe. The purpose of this study was to determine the effect of the furious form on the surface roughness of the S45C material. This study used factor variables that are thought to affect the shape and surface roughness of the S45C material, namely, the cutting angle of the chisel with a level (80o, 82o, 84o), feeding depth with a level (0.4 mm, 0.6 mm, 0.8 mm) and Spindle rotation with levels (200 RPM, 280 RPM, 360 RPM). The lowest surface roughness value for the S45C material was obtained from the variation of the chisel cutting angle factor of 80ยบ, infeed depth of 0.4 mm, and spindle rotation of 280 RPM with a surface roughness value of 5.171 . From the lowest value of surface roughness, a tubular growl (short) is produced.

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.
