The reasons to shift the generation system from conventional fuel oil generating system to clean energy sources are now based on the increase of fuel cost, climate change and environmental issues in reducing the greenhouse gas emission and also pollution. Wind is one of the renewable energy that has many advantages and the level of the penetration has increased now. Despite the abundance amount of wind, the fluctuation and the intermittent make wind generation system can affect the reliability of the power system. One of the solutions to the problems above is the use of electrical energy storage system. Power that stored in the electrical energy storage system can be used later when the wind is not strong enough to generate electric power. This research intends to investigate more on li-ion battery as one of the promising means in enhancing the reliability of power system when connecting to wind generation system in order to enhance the power system reliability. This work should contribute significantly in wind energy generation stability improvement with the storage system and there will be an advantage in battery storage system application. The results show the stability improvement of the simulation system connected to the wind generation with the battery.

A quadrotor is an unmanned aerial vehicle (UAV) with two pairs of rotors rotating in opposite directions. Some of its unique abilities are hovering and vertical take-off and landing (VTOL). Most recent works carried out the UAVs' rotation parametrization using Euler angles and a quaternion. Those UAVs suffer from singularities and ambiguities. A geometric control is generally used to deal with those problems. Exponential coordinate in the geometric control maps R3 into SO(3). This paper presented a fuzzy logic controller on SO(3) to control the attitude of the quadrotor. The input of the fuzzy logic controller is the angular velocity (ω) and exponential coordinate error of rotation (ζ), while the output is torque (τ). The error function in this controller is a rotation matrix on SO(3). This proposed controller can control the attitude of the quadrotor based on the expected attitude for maneuvers both on one axis and all axis with a steady-state error of about 0.02 rad.

Kondisi udara di kota-kota di Indonesia terutama daerah dengan ketinggian cukup dekat dengan permukaan air laut, kurang memberikan kenyamanan karena udaranya yang panas akibat meningkatnya pemanasan global. AC (Air Conditioner) adalah alat yang dapat digunakan untuk membuat kondisi udara berubah menjadi nyaman. Perhitungan daya listrik dari kebutuhan AC untuk sebuah gedung perkantoran yang beralih fungsi menjadi ruang serbaguna dilakukan. Dari hasil perhitungan maka terlihat bahwa daya yang dibutuhkan untuk sebuah gedung perkantoran yang beralih fungsi menjadi ruang serbaguna adalah sebesar 92,5 kW.

This study aims to describe the testing of electrical energy in the rooms of the Sotis Kupang Hotel from the 2nd (second) to the 6th (sixth) floor, taking samples of 7 (seven) different room types and carried out a test of electrical energy in relation to the use of lamps and air conditioning. The method used in this study is data collection, survey, observation and direct measurement of the use of light and AC (air conditioning). The data analysis technique used is to determine the estimated value of the electrical energy consumption and the value of the energy consumption intensity (IKE). The calculation and analysis show the value of IKE is 30.96 kWh / m2/ year, which is categorized as "very efficient". The IKE value for the use of AC (air conditioning) is 206.33 kWh / m2/ year and which is categories as "somewhat wasteful". The calculation of the PHE (energy savings) results in a PHE for the use of AC of 172.88 kWh / m2/ year, which falls into the category of "fairly efficient.

Gedung Keuangan Negara (GKN) of Kupang is the office for the affairs of the state finance and assets. The Franklin type lightning in the State Finance Building is not functioned properly and the value of resistance is quite large plus the number of thunder days in Kupang city reaches 80 thunder days and 128,504 lightning strikes in 2019 according to data from the Kampung Baru Kupang Geophysical Station. The results of primary and secondary data collection according to Indonesian National standards (SNI 03-7015-2004) Gedung Keuangan Negara must be protected from lightning induction because the value of the annual average frequency of direct lightning strikes (Nd) > the allowed local annual lightning strike frequency (Nc). Electrostatic protection is selected for the electrostatic type with a Flash Vectron FV6 type with a radius of 50 to 150 combined with a Faraday cage of 8 finials and funneled through a Bare Cooper conductor 50 mm^2 to grounding system planted in the ground with a rod type electrode diameter of 12 millimeters in length. The electrodes planted varied, namely 0.5 meters, 1 meter and 1.5 meters. The value of grounding resistance R<5 Ω is in accordance with the PUIL 2011 standard. The value of earthing resistance R_average L_(0,5 m)=171,6 Ω, L_(1.0 m)=128,6 Ω and L_(1,5 m)=73,4 Ω. To fulfill the requirements according to the PUIL standard, the number of rods in L_(0,5 m) must be added with the value of R_paralel = 3,7065 Ω for 100 electrode rods, for L_(1 m) with a value of R_paralel= 3,9682 Ω for 70 electrode rods, and for L_(1,5 m)= 3,1708 Ω for 50 electrode rods.
