Abstract

Energi air adalah salah satu jenis energi terbarukan, yang dapat diartikan sebagai energi yang dibangkitkan dari energi potensial atau energi kinetik air. Biasanya energi kinetik atau energi potensial air dikonversikan menjadi energi listrik, melalui alat konversi (turbin dan generator) yang kemudian di distribusikan. Turbine type screw akan menghasilkan perputaran akibat dari aliran air yang mengalir disekitar screw. Dimensi turbin screw yang di buat menggunakan plat 3 mm, diameter poros screw 20 cm (Ri) dan diameter screw 40 cm atau diameter luar (R0). Dan trubin screw yang di uji sebanyak 3 turbin screw dengan perbedaan pitch. Jarak pitch yang digunakan adalah 1,6 R0, 2 R0 dan 2,4 R0. Pada penelitian ini menghasilkan effesiensi daya untuk masing – masing turbin dengan jarak antar pitch berbeda yaitu effesiensi daya untuk turbin screw dengan pitch 2,4 R0 adalah 55,63%, untuk turbin screw dengan pitch 2 R0 adalah 64,8% dan untuk turbin screw dengan pitch 1,6 R0 adalah 64,9%.

Abstract

Small and medium industries are growing rapidly, one of which is the bottled drinking water (AMDK) industry. Therefore, there are so many studies related to the automatic filling of mineral water in both 250 ml and 600 ml glass packaging. However, this research focuses on an automatic water filling system that is controlled by a microcontroller or PLC so that it ignores the container queuing system in the form of glasses or bottles automatically, in the sense of the research the container queuing system is still done manually. The queue of glasses that are arranged in stacks becomes one of the obstacles, because the distance between the first glass and the second glass and so on is very small and can even be said to be close together. This research focuses on the mechanical system to take the glasses one by one which is arranged in a stack between glasses using acrylic material in the shape of a rectangle at a size of 100mm x 180mm. This mechanical system is to separate the bottom glass from the pile of glasses by pushing the bottom glass separator mechanically, using a pneumatic cylinder that moves horizontally. The results of the research are the process of taking 250 ml glasses one by one in a stack of glasses automatically 100% with a minimum stack of 4 glasses.

Abstract

Sugarcane juice can be taken by squeezing sugarcane stalks using a squeeze machine. The existing squeezing machines are still not efficient and relatively low production speed. The main factor of machine performances was on rolls quantity and its arragement. To overcome this problem, we have designed and fabricated the machine with 3-rolls by optimally speed and inter-rolls distance setting. The squeezer rolls were driven by 1-phase motor with fixed speed by the gear ratio setting. The distance and position between the rolls are arranged in such a way that the pressing power is maximized, but it is maintained to avoid stuck. The peeled and cut sugarcane is loaded into the hopper. Then, the sugar cane is drawned and squeezed by rolls. After that, it filtered and stored in the container. This machine is equipped with an automatic system for dispensing sugarcane juice from the container to the glass. The results show that the efficiency of this machine is around 65.1% with 78.1 ml/s production speed. Sugarcane juice produced is relatively clean without contaminated by it dregs
