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.

in the future, which would greatly support the success of the Faculty
of Engineering University of Mataram towards "Go International" in
2025.
The theme of the 1st AEMT is” The Lombok Geomagnetic
Observatory Inauguration”: a support for environmental monitoring
& discovery of new natural resources. Underlying this theme is the inauguration of the
Lombok Geomagnetic Observatory that has launched on 11 April 2014 in Central Lombok
District by Minister of Research and Technology.
The aim of this International Conference is to provide an international forum for
exchanging knowledge and expertise as well as creating a prospective collaboration and
networking on various fields of science, engineering, and especially, applied geomagnetic
technology along with its supporting fields.
Although this first international conference is a specific themed conference, many of
interested speakers participate to present and discuss their ideas related with geomagnetic
and its various supporting fields such as New-Renewable Energy, Telecommunication, signal
processing, Data Management & Information Systems, and Miscellaneous related aspect to
Electromagnetic Technology.
This conference will have 3 keynote speakers, 4 invited spaekers, and has gathered 43
papers from various universities and intitutions from both domestic and overseas.
My deepest appreciation to our speakers, observers, sponsors, contributors, and supported
parties who have given their generous supports. I would also like to thank all members of
the Organizing Committee and our distinguished Reviewers for all of their supports and
advices as well as the IJTech Journal of University of Indonesia that wiil publish some

Abstract— Water is a potential source energy in Indonesia.
Supply power capacity by PT. PLN (persero) insufficient to
public demand of electrical energy. Micro Hydro Power ( MHP )
is a small-scale power plants
model relatively easy to
development but MHP location usually at remote areas, away
from residential and network of PT.PLN (Persero) unavailable.
energy generated by MHP unused directly around the site of
generation, but must be transmitted through a power
distribution network. In this study researchers wanted to answer
the problems that arise how to make a model of the control
system is arranged to be connected MHP to network low voltage
distribution PT.PLN(Persero). Smart control system, the
electrical energy generated by the MHP will be controlled
automatically in the event of disruption or change in load. New
method to be used is the output of the MHP will be automatically
control system, results from this study is a high success rate of
the control system for MHP with fuzzy logic .

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.

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.

C. Excitation Controller
The basic requirement of the excitation system is to
maintain the machine terminal voltage by automatically
regulate the synchronous generator field current including
during disturbances.[5][6][7][8] In conjunction with this, IEEE has
produced several recommendation excitation system models to
cater different purposes. The output field voltage is regulated
by the control system of the exciter in order to maintain the
system voltage at Vref.
Transforming Electric Grid by using smartcomputational
algorithms, devices, and electronics into a highly efficient and
reliable “Smart Grid” [9][10][11][12] is needed now.stochastic
