Abstract

A short circuit is a common fault of overhead lines. In 2015, short circuit caused by surge lighting and fallen trees, occurred four times in transmission line connected PamonaSiderasubstation. In securing transmission line, distance relay should be applied as the primery protection. However, incorrect setting of relay may readily lead to relay failure to protect the line. Therefore, evaluation of relay setting is crucial. The purpose of this paper is to evaluate the setting of distance relay that was installed at Pamona and Sidera substation. Furthermore, calculation of curent fault and impedance of short circuit was done by intervering fault to the line connected Pamona and Sidera substation in matlab. The method used is simulation using matlab application. The result shows that the highest short circuit current obtained at 25% of the length of Pamona-Sidera transmission line, 6203.47A. The smallest short circuit current was 1255,86A, occurred at 100% of the Keyword : Short Circuit, Distance Relay, Transmission line

Abstract

Digital era demands all thing could be done in computerized system to solve problems in easier way. So do with verification and identification system that continues to evolve with technology development. One of the implementations of it is face recognition. Human faces were taken as verification and identification system because they have unique characteristic and identity between one and others. Face recognition implementation on computerized system could be done with eigenface algorithm. Eigenface is one of face recognition’s algorithm based on Principal Component Analysis. Based on the best threshold value prospecting, it’s obtained for 2400, that value obtained for 100% of face recognition success rate. The image that can’t be detected and recognized as someone’s face is an image that has image distance error greater than predetermined threshold value and due to significant difference in light intensity of training images and test image.Keywords: Eigenface, Image, Euclidean Distance, and Face Recognition

Abstract

One of the technologies that utilizes solar energy in delivering electric energy isphotovoltaic (PV) system. It converts solar energy into electric energy directly which is environmental friendly, non-pollution, not taking fossil fuel and low cost maintenance. Mineral Resources (ESDM) is one of the offices which uses PV system in Palu municipality. However, only 3 AC powered by non battery-PVis used in ESDM. In the future, ESDM have planned to add the capacity of PV system to supply the other AC. The objective of this study was to design PLTS system for supplying other AC and lighting especially in evening. In thiscase, sun panel capacity, battery, BCR, and inventers will be determined. This study also aims giving information about investment cost which is needed by PLTS with battery without battery and PLN. The calculation in this study used data from BMKG Meteorology Station Palu and Mineral Sources (ESDM) office of Central Sulawesi. The results showed that the capacity power for supplying Air Conditioner charge and lighting in evening was 122,54 kWh, where the systemsvoltage was 120 volt. moreover, the number of sun panel was 40 unit with capacity 200 Wp, 15 unit for battery with capacities 24v 1000Ah.Keyword : Photovoltaic design, Battery, BCR, Inverter, Early Investment

Abstract

One major factor to support rural development is the availability of electrical energy. Given the geographical condition of Indonesia which consists of the islands are small and many are isolated, an estimated 6,200 villages would not be possible or very difficult in electric stream by way of the expansion of the grid. Therefore we need a technology solution that can exploit or overcome the limitations of the energy sources. One of the alternatives that can be done is the utilization of solar energy using solar cell or photovoltaic sensors in the form of solar panels. Based on population growth, and the current economic growth, the Government seeks to procure solar power plants each year to facilitate villages that have not received a solar power plant. It is necessary for forecasting solar power plant needs long-term so that the procurement of solar power plants will be optimized. The forecasting is done by projecting using fuzzy logic. From the analysis of the estimated total demand for solar power in the district of Parigi Moutong using fuzzy logic can be seen as follows; needs of solar power plants by 2016 is 1090 units, the need for solar power plants in 2017 is 1220 units, the need for solar power plants in 2018 is 1350 units, the need for solar power plants in 2019 is 1470 and the need for solar power plants in 2020 is 1580 units.

Abstract

The use of electrical energy in University is an absolute and unavoidable. Based on data obtained, every year Tadulako University experienced a high increase in electrical energy consumption. The electricity bills of Tadulako University based on data 8 months from January to August 2015 reached Rp.2.567.411.878 that is in average of payment per month of Tadulako University is Rp.322.051.485.At the substation of FISIP electricity usage in January through August 2015 was highest in June reaching 61.750 kWh to the cost of electricity bill as big as Rp.55.575.000. Electric energy audit begins with the historical data collection of electricity biil in the last three years such as : the substation of FISIP on January to August, the data load of electrical equipment, and the spacious rooms supplied. The intensity of energy consumption and the energy-saving opportunities were counted from each supplied rooms of substation FISIP. The result of the calculation of the intensity of energy consumption in detail can be seen throught 160 total rooms if the energy-saving opportunity of 49 rooms is implemented. Therefore, Tadulako University can save the cost of electricity by Rp.30.140.900,73 per month.

Abstract

The development of control systems has now reached a level that better facilitate the work of man. Most of control systems have been used in industrial companies.However, there is another thing that also have important rule in making easier the human's assignment which is in form of manual control, namely the simulation display system, installed on a device that is used to control theequipment using display on PC (Personal Computer) without facing them directly.This system has started to be implemented and applied by some modern industries. One example of the use of simulation display system is the construction of the simulation of reverse osmosis systems on PLTU (steam power plant) in order to facilitate the operator to run the simulation test. The problem statement created in this research was how to design the simulation display of reverse osmosis systems using the programming language of Macromedia flash 8, Delphi,ISIS Proteus, and Micro Pascal and then communicate it with the simulation of microcontroller based reverse osmosis systems. The result of this research is the simulation display of reverse osmosis systems which iscreated manually and automatically. The systemis communicated with the simulation of microcontroller based reverse osmosis systems where there are five motors and three tanks.The motors will drain the water of each tanks through the filtration process. Later on, the pure water as the final result of the filtration process will be used for steam cycle process in the boiler. Keywords: Simulation display, Reverse Osmosis Systems, Macromedia flash 8, Delphi, ISIS Proteus. I. P
