Abstract

Lubrication can be interpreted as the provision of lubricants on a machine with the aim to prevent direct contact between the moving surfaces. Viscosity is a very important trait in lubricating oils. The viscosity of lubricating oil indicates the ability and ease of lubricating oil flowing. Distance is a number that indicates how far an object changes position through a particular path. This research method using Yamaha mio 110 cc motorcycle. Using SAE 10W-40 oil with the initial viscosity of oil A(3.17), B (5,18 ), C (15,0 ). Then tested with a distance of 30.60 and 90 km with a constant speed of 70 km / h and then taken the oil sample. The result of the test is calculated using the viscosity formula with the law of Stockes. When it was on 90 km speed, Oil C still shows the highest viscosity with a value of 2.55, while oil A remains the lowest viscosity with a value of 1.70 . This study shows that the higher the viscosity affects lubrication. The more oil layers, the lubrication can do better and the duration to changes the oil will affected too (longer).

Abstract

Drying is the process of reducing water content to reach a certain moisture content. The drying process of mussel cauliflower in Balongdowo village still relies on sunlight in the drying process. Drying with this process is considered to be less efficient because when the hot rainy season the sun is unpredictable and requires extensive land in the drying process. To overcome this problem, in this final project, the title of the design of cracker dryer is taken using heater heater. Which is expected to increase effectiveness and productivity when the rainy season arrives can also reduce the time and production costs. The method used to solve these problems is to use the bootroyd design method which is designing a dryer that consists of the main components of the drying chamber, conveyor, drive motor and gearbox. The results of the test showed that the drying time of 76 seconds reduced the initial water content of 70% reduced to 15% the water content contained in crackers.

Abstract

Salah satu masalah sistem perpipaan adalah rugi aliran (head lossess) akibat penggunaan reducer dan elbow. Kerugian head (head loss) sangat merugikan dalam sistem perpipaan, karena head loss yang besar menyebabkan tekanan fluida menjadi lebih rendah dari yang diharapkan sehingga suplai fluida tidak mencukupi. Tujuan penelitian ini adalah untuk mengetahui jarak pemasangan reducer dan elbow yang optimal untuk mencapai headlosses minimal.Metode yang digunakan adalah true experiment research dengan membuat alat uji headlosses dengan variasi debit air sebesar: 20, 25, dan 30 L/min, serta variasi jarak elbow: 6, 12, 18 cm. Hasil pengambilan data secara eksperimen menunjukkan bahwa pressure drop dan head losses terbesar terjadi pada debit 20 L/min dengan jarak elbow 6 cm, yaitu sebesar 0,207 bar dan 2,115 m. Sedangkan pressure drop dan head losses terendah terjadi pada debit 30 L/min dengan jarak elbow 18 cm, yaitu sebesar 0,057 bar dan 0,580 m.
