Abstract

Central Sulawesi has tropical climate conditions with interconnected rivers caused each of it can experience the impact of the sudden rise of water levels if there is a heavy rainfall in upstream areas which is commonly called “a sent flood”. Therefore, it is needed an early detector flood tool that works based on the height of river water level so that the impact of floods can be minimized. Early detector flood tool can function automatically by giving early warning when water levels reach a certain limit. The detector of height levels of river streams is designed using float magnetic level gauge method. This height level of river streams detector is able to provide information in real time based on the height level of river streams by giving information in the form of warning light indicator and siren alarm as alert and danger sign. Key words: detector, early, flood, float, magnetic.

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

Electricity is a secondary energy form that is generated, transmitted and distributed for all kinds of purposes. Tadulako University Campus an electricity consumer with considerable power and continue their development rapidly. Because of the construction, the electrical load is also increasing, the medium-voltage network as one of the components of the power system needs to be evaluated in order to serve the load capacity continuously. Electrical power is supplied from distribution transformers to user have voltage loss and power losses. Because the distribution network has resistance, inductance, and capacitance. The energy lost already appeared from the generation system. This study was conducted by analyzing model of the single line diagram with input medium voltage-network Tadulako University campus data in ETAP 7.5.0 application. From the analysis, there were losses in the medium voltage network Tadulako University Campus at 1.358% with 0.39% voltage drop at the existing load.

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

Indonesia is a country that has an area of sea three times larger than the land area. In line with the rapid development, the need for electricity is also increasing. So that Indonesia has great potential to produce alternative and environmentally friendly energy, namely Sea Wave Energy. Its continuous nature is available all the time. Many potential coastal areas in Indonesia, however, have not been utilized optimally. The purpose of this study is to see the potential of Wave Energy for electricity. For this reason, research was carried out at a location in the Central Sulawesi area, precisely in Salubomba, Central Banawa District, Donggala Regency. In this study a potential study was conducted on 3 types of PLTGL, namely Buoy, OWC, and Pasut Dam, where one will be chosen that meets the wave criteria requirements on the Beach. From the results of research, PLTGL that fulfills the requirements is the type of buoy. Data collection begins with secondary data, namely wind data from Mutiara Station. Then proceed with calculating wave forecasting using the SMB (Sverdrup Munk-Bretschneider) method. The results of this study, Salubomba beach has the potential to be built by the Buoy Type Wave Power Plant, a significant wave height of 0.52 - 3.37 meters with a ruptured depth of 3.95 meters.

Abstract

Heat transfer is the transfer of energy from one area to another due to the temperature difference between these areas. Wasted heat energy can be converted into electricity using (TEG) between the hot and cold sides. If the temperature difference is more significant, the efficiency may increase along with the operating temperature of the TEG-type material. So in this study, the author will calculate the heat transfer that occurs in Photovoltaic (PV), Thermoelectric Generator (TEG), and Hot Mirrors by utilizing thermal energy light produced from Muxindo LED bulbs with 10 Watt, 15 Watt, and 20 Watt power. The results of this study indicate that by using 10, 15, and 20 Watt LED bulbs for free convection heat transfer, the power generated from each point increases because it passes through several obstacles from objects that experience a decrease in temperature to PV and TEG, with the characteristics of the displacement. The movement of molecules from the medium importance follows convection heat at every point of transfer in the intermediate substance. The most significant power generated from radiant heat transfer is about 0.1873 Watt. It occurs on the surface of the fresnel lens using a 20 Watt LED bulb with the characteristic that the radiation propagates in a straight line and does not require an intermediate medium to transfer heat from one substance to another. The most significant conduction heat transfer power, 0.2453 Watt, occurs in Fresnel Lens using a 20 Watt LED bulb with heat transfer characteristics in solid objects.
