Abstract

The control system degrees of opening and closing the valve in the steam distribution system water jacket heating process using the controller 328 ATMega microcontroller is designed to make it easier for workers to do the process of controlling the temperature of the water in the jacket. Another benefit is to be able to avoid failure in the liquefaction process in palm oil so that the oil in the previous pegolahan pipeline flowing. The method used in this research is the design that consists of several stages, namely, (1) Analysis of needs, (2) design, (3) Implementation of the circuit, (4) Testing Procedures and (5) Testing tools. The equipment is made LM35 temperature sensor, microcontroller minimum system ATMega 328 is Arduino Uno as a series of input and output controllers, servo motors as output (valve) is controlled, and the LCD as a viewer device temperature detection results. While the software is created using arduino and language "C". The performance of the whole device can work well, so that it can be implemented with matching devices in the field or in the industry.

Abstract

Abstrak — Energi angin merupakan salah satu energi alternatif yang dapat dimanfaatkan untuk berbagai keperluan guna menggantikan sumber energi berbahan bakar fosil. Salah satu bentuk dari  pemanfaatan energy angin adalah sebagai sumber energi untuk pembangkit tenaga listrik. Pengujian turbin tipe horizontal dan vertical untuk mendapatkan besar kinerja turbin dengan variasi jumlah sudu turbin, sudut kelengkungan turbin dan kecepatan aliran udara. Kinerja turbin dapat dilihat dari besar efisiensinya yang merupakan perbandingan daya keluaran terhadap daya masukan. Daya input turbin diperoleh dari pengukuran laju aliran udara dan luas permukaan penampang turbin yang menerima aliran udara, daya input akan divariasikan dengan memvariasikan laju aliran udara. Dari hasil penelitian  variasi 4 sudu dan 8 sudu. Didapat variabel bebas adalah variasi jumlah sudu. Maka rata-Rata variasi 4 sudu dari hasil penelitian diatas didapatlah rata-rata dari Daya angin sebesar 96,2 Watt dan daya turbin angin sebesar = 4,9 Watt, Maka rata-Rata variasi 8 sudu dari hasil penelitian diatas didapatlah rata-rata dari Daya angin sebesar 77,4 Watt dan daya turbin angin sebesar = 2,78 Watt.Kata kunci :  PLTA,Variasi Sudu 4 dan 8, Daya Angin dan Daya Turbin AnginAbstract — Wind energy is an alternative energy that can be utilized for various purposes in order to replace fossil fuel energy sources. One form of utilization of wind energy is as an energy source for electricity generation. Testing horizontal and vertical type turbines to get the turbine performance with variations in the number of turbine blades, turbine curvature angle and air flow velocity. Turbine performance can be seen from the large efficiency which is the ratio of output power to input power. Turbine input power is obtained from measurements of air flow rate and surface area of the turbine cross section that receives air flow, input power will be varied by varying the air flow rate. From the results of research variations of 4 blades and 8 blades. Obtained an independent variable is the variation in the number of blades. Then the average variation of 4 blades from the above research results obtained an average of 96.2 Watts of wind power and wind turbine power of = 4.9 Watts, then the average variation of 8 blades from the results of the above studies obtained an average of Wind power is 77.4 Watt and wind turbine power is = 2.78 Watt.Keywords :     Hydroelectric Power, Variation of Blades 4 and 8, Wind Power and Wind Turbine Power
