PREFACE WELCOME FROM THE DEAN OF FACULTY OF ENGINEERING UNIVERSITY OF MATARAM First of all, let us praise God Almighty who has bestowed upon us His blessing and thus allow us to participate in the very important event for academicians and scientists around the world. I am delighted that the EMTech Research Group of Faculty of Engineering University of Mataram in co-operation with University of Indonesia and GFZ Potsdam Germany are finally able to organize the strong academic tradition called the 1st International Conference on Applied. Electromagnetic Technology. The 1st International Conference on AEMT is the culmination of more than one year hard works by the joint committee since the typical event needs a long and well preparation. As a very prestigious event involving many scientists and researchers from different continents, it is truly an honor to organize and to host this scientific event. We have to admit that Indonesia only contributes a very small part in top-rated research. In our home countries, it can hardly go unnoticed that there is a serious lack of world-class scientific institutions, and yet disturbingly we also see that there is no lack of scientific talent. The existence of Lombok Geomagnetic Observatory can bridge this unusual and extraordinary imbalance. The observatory renders an important contribution for the scientific investigation of the Earth’s interior and environment. In the future, the investigation from the observatory will benefit the global research community when the observatory joins the Intermagnet network. The interest from researchers and scientist around the world is a clear signal that in the right term, global community and Indonesian government together with local authorities can expect to feel positive effect from this event. We are certainly looking forward to bringing this initial step of inauguration of the Lombok Geomagnetic Observatory to the world scientific community. This not beyond our reach if we can establish the links with other key players in the associated areas. The majority of participants who are representing higher institutions as well as research institutions show the importance of the role that the universities and research institutions have to play in bringing quality researches into global development. Finally, I would like to express my sincere thanks and appreciation to all sponsors who contribute to this event. To all participants who have come from different continents, I would like to extend my very warm welcome to this conference. I wish you all to have a productive and fruitful discussion.

Yusron Saadi, ST., M.Sc., Ph.D Dean Faculty of Engineering, University of Mataram

INTRODUCTION

Impact of excessive energy use for this is the cause of air pollution, global warming and climate change. Water energy is an environmentally friendly energy source, green, unlimited and renewable nature. All countries in the world today continues to conduct research on water energy, wind and solar, which is used as one of the future energy development policy options. Proven installation of Renewable Energy is currently in parts of the world increased to 30%. [1][2][3][4] The energy plays an important role for population in the world. The energy demand is significantly increases every year but the energy resource is limited and decreases especially conventional energy. Hydropower is one of clean energy resources in the world. It is also the most reliable and effectively cost renewable energy resource among the others. Small hydropower schemes are getting increasingly popular because of its simplicity design, ease in operation, and lower environment of heavy construction in comparison to large hydropower schemes. Conventional highly efficient low head hydraulic turbines, such as Kaplan, become economically unviable because of the large size of the turbine required for very low head installations, requirement of special flow control mechanism and the risk the impose on the ecology especially on fish, trash and sediment transport. This study focused on discussing the frequency and phase control of the generator mounted on the MHP to be set for frequency changes (Δf) and phase (ɸ) by using a low voltage grid reference of PT. PLN. Control is used is to utilize fuzzy

logic consisting of 7- rule members ship function to control error (e) and change of error (de). Block Control of micro hydro set including the components of governor, valves, turbines and generators are made in the transfer function. Fuzzy logic uses to reduce the error from occurring plant using Matlab. Fuzzy logic controller has 2 input e and de and one output u. II.

LETERATURE REVIEW

A. Hydraulics power theory Theorem of water flow is used to determine the amount of energy that can be generated from the flowing water. The total extractable hydraulic power from the flowing water is given by the expression of Pin = ρ x g x Q x H, where Pin is the hydraulic power input to the wheels (W), ρ is the density of water (kg/m3), g is the acceleration due to gravity (9,81m/s2), Q is the volumetric water flow rate (m3/s) and H is the difference in total energy line upstream and downstream of the wheel (m). The angular velocity ω (rad/s) of the wheels is calculated from the number of revolutions N at the given load in revolutions per minute (RPM) of the wheel as : ω = 2 x π x N/60. The shaft torque τ (Nm) is the product of the force F of water striking the blades of the water wheel (N) and the moment arm length (m) which, in this case, is the radius of the pulley r. Force is equal to the differences in the mass obtained from the two load cells time the acceleration due to gravity. τ = m x g x r. Subsequently the mechanical power output Pout available at the wheel shaft is determined from the measured torque τ and the corresponding angular speed of the wheel ω as : Pout = ω x τ = 2 x π x N x τ/60. by calculating the power of output and input, the mechanical efficiency η of the wheel is therefore : η = Pout / Pin x 100% Automatic control system of micro-hydro is built in a closed loop. First some water are flow in the valve, it continue to the spill way and rotate the turbine. The control system of MHP as shown at Figure 1 B. Governor Controller Control for hydro power plant, hydraulic mechanical governor and electro-hydraulic (PID Controllers)[4] are commonly used. The study of micro hydro in Gambuk, Bali [1],[2],[3] don’t have a controller for the Governor. Using governor for control system MHP is better than none because the system becomes very difficult when to connect with a grid owned by PT. PLN as shown in Fig 2.

Abstract— The capacity of electrical energy supplied by PT. PLN (persero) insufficient to public demand in Indonesia. Micro Hydro Power Plant ( MHPP ) is a small-scale power plants which relatively easy to developed in remote areas. The generated energy by MHPP must be transmitted to the distribution network. In this study researchers wanted to answer the problems how to make model auto control which connects the MHPP with network distribution of PT.PLN (Persero). The result of this study is MHPP can be auto controlled by controller of I, PI, PID and Fuzzy-I. Smart control of Fuzzy-I controller makes the system to stable with a small overshoot values. It is better than controller of I, PI or PID.

This study focused on discussing the frequency control of the generator mounted on the MHPP to be set for frequency changes (Δf) by using a low voltage reference of PT. PLN(Persero). This control is using fuzzy logic consisting of seven rule member’s ship function to control error (e) and change of error (de). Block Control of micro hydro set including the components of governor, valves, turbine and generator is made in the transfer function. Fuzzy logic uses to reduce the error from occurring plant using Matlab. Fuzzy logic controller has two input e and de and one output u. II.
