Abstract

Dalam bidang rekayasa kavitasi didefinisikan sebagai proses pembentukan fase uap dari suatu cairan ketika cairan tersebut mengalami penurunan tekanan pada suhu sekeliling (ambient temperature) yang tetap. Kavitasi merupakan fenomena yang merugikan dalam operasinal kapal, karena menyebabkan banyak kerugian. Pengaruh yang merugikan tersebut berupa menurunnya efisiensi propeller, merusak material propeller, kecepatan kapal menjadi lebih rendah dan menyebabkan getaran dan kebisingan. Oleh karena itu dalam penelitian ini dilakukan analisa kavitasi pada Controllable Pitch Propeller (CPP) dengan melakukan variasi jumlah daun yaitu 3 , 4 dan 5 daun, variasi diameter yaitu 30, 40 dan 50 cm, serta variasi pitch yaitu 0.4, 0.6, dan 0.8. Metode yang digunakan dalam penelitian ini adalah metode simulasi. Hasil simulasi menunjukkan bahwa perbedaan putaran propeller memiliki pengaruh terhadap besarnya nilai perbedaan tekanan. Semakin meningkat putaran propeller maka nilai dari perbedaan tekanannya akan semakin meningkat pula. Perbedaan design propeller memiliki pengaruh terhadap area kavitasi yang terjadi pada propeller. Prosentase area kavitasi yang terjadi pada propeller memiki kecenderungan naik pada jumlah blade, putaran serta pitch yang semakin meningkat pula.

Abstract

Agriculture is the primary livelihood for most of Indonesia's population, which has vast agricultural land. However, there remains a dependency on chemical fertilizers, which degrade soil quality compared to organic farming that can optimize plant health and productivity. The energy needs in the agricultural sector, including mechanization and fertilizer production, are critical but still heavily reliant on fossil fuels. It is, therefore, essential to reduce this dependency by utilizing environmentally friendly alternative energy sources. This study examines the use of solar energy to power machines in the process of producing organic fertilizer. The tools used in the study include a 100 Wp solar panel, solar energy conversion components, a 12 Volt 33 Ah battery, a ¼ Hp electric motor, a voltage and current meter, a temperature gauge, a sunlight intensity meter, and an organic fertilizer processing machine. The research method analyzes several variables, including sunlight intensity, power, voltage, current, charging time, and battery usage. The study found that the solar panel used was insufficient to power the ¼ HP motor, requiring the addition of three more solar panels and batteries to meet the motor's power requirement of 233 watts. Battery charging tests required 3 hours, and battery usage for machine operation without solar panel installation lasted 1 hour and 40 minutes, while battery usage for machine operation with solar panel installation lasted 6-7 hours. Keywords: Environmentally friendly energy, Fertilizer crushing machine, Organic fertilizer, Solar energy.

Abstract

The high demand for jewellery products increases significantly every year, but the export requirements of the products demand high quality. So, efforts are needed to improve quality, support cost savings, reduce energy needs, and improve work safety, especially in the casting process of jewellery products. This study aims to analyze the implementation of practical quality control standards to improve the quality of jewellery product casting. This research method uses a Plan-Do-Check-Action process approach that refers to ISO 9001, 14001 and 45001 standards. Implementing the PDCA (Plan-Do-Check-Action) process approach adopted in developing quality control methods in the jewellery casting process proved effective, resulting in casting shrinkage of 0.2 kg below the established standard of 0.7 – 1 kg. Controlling temperature casting below the melting point can also provide energy savings and heat control of the casting process to reduce occupational safety and health hazards. PDCA quality control methods can improve the quality of casting jewellery products by reducing porosity defects and shrinkage, saving energy, and reducing occupational safety hazards. This research provides an effective quality control method for the jewellery casting production process regarding quality improvement, environmental management, and safety to achieve the Company's sustainability.

Abstract

Anchor is a device for tethering a ship to the bottom of the water, in the sea, river, or lake, so that it does not move from place to place due to gusts of wind, current, or waves. Anchors are heavy equipment that is dropped to the seabed from a ship or boat to maintain its position so that it does not drift. PT X has several tug boats, small vessels whose function is to pull or push large ships in port. In addition, this ship also functions to pull barges filled with coal from the coal processing plant to be brought to the port, where the coal is unloaded to be carried by transport trucks. On these barges, damage to the anchor machine often occurs, especially the teeth on the gear-box, axle pulleys (pulleys), the main shaft of the main-gear (main gear), the gear-box casing, the teeth on the main-gear and others which have been sufficient so far. Interfere with operations, and the ship becomes idle. For this reason, this research was conducted to study the change in the anchor system from the glide model to a new system in the hanging model, in order to reduce the use of anchor winch power and avoid damage to the gear-box and anchor engine.
