Abstract

Abstract—Public street lighting (LPJU) is a road infrastructure that is very important for road users at night. The constraints faced by User managers in an area in LPJU management are the problem of maintenance, monitoring, electricity consumption, and limited workforce. In an effort to overcome this problem, this study designed a tool in the LPJU system that can control LPJU ignition according to user needs by combining the timer and light sensor functions, and can monitor electricity consumption by calculating the power consumption or kWh meter and recording data on accumulation of electric power consumption every day at 06.00 WITA automatically stored on the micro SD Card. The accumulated data last recorded for 1 (one) month at the beginning of each month at 08.00 WITA will be sent using SMS services to users periodically. In addition, the user can monitor at any time with the "lapor" SMS format, the monitoring data sent in the form of the last electrical power consumption used by LPJU at that time.

Abstract

possibilities of the source of geomagnetic anomaly in Lombok Island, i.e. a specific local structure composed by a quite large magnetic body or a local fault in this region that could be associated with a source of seismic hazard (especially earthquakes). An interesting profile could be estimated lie around the minimum geomagnetic anomaly (8045’36”S, 11601’48”E) to the maximum one (8043’48”S, 1160 5’24” E). Understanding the corresponding structure on that profile is very important - related to the possibility of the source of geomagnetic anomaly in Lombok Island - in order to get further information about potentially local fault in this region as a source of earthquakes hazard. Geoelectric method with vertical electrical sounding (VES) configuration have been applied in this profile, on three VES points (i.e. one point between the minimum and the maximum geomagnetic anomaly (X1: 8046’42.9”S, 116004’07.7”E), and two other points outside (X2: 8046’03.3”S, 115058’39.9”E; which is on negative anomaly area) and (X3: 8042’11.6”S, 116008’27.2”E; which is on positive anomaly area). The potency of X1 as a critical zone has been shown, with the existence of resistivity contrast in this area, which its resistivity value between X2 (very high resistivity; r >25,000 Wm) and X3 (very low resistivity; ; r >1 W m). This results lead to the potentially local fault in this region as a source of earthquakes hazard.

Abstract

Abstract— Most of the power plants use fossil energy sources, while fossil energy has several undesirable effects. To overcome this, it is necessary to develop in electricity that is by using renewable energy as a source of electrical energy. Some examples of electrical renewable energy sources used are solar energy and wind energy. Renewable energy as electricity generation can be developed using a microgrid concept, generation with more than one power plant. The combination of different types of power plants is often called a hybrid power plant. One example is a hybrid power plant with a smart microgrid network system at the Department of Electrical Engineering, Faculty of Engineering, Udayana University, which has been operating since 2017, which is a collaboration between Udayana University and the Ministry of Energy and Mineral Resources (ESDM). This smart microgrid requires a study of the energy supply system of the power generation in order to know its performance to serve the DH building load. The study will analyze the data in October 2018. Research results show that smart microgrids cannot fully meet the electricity load in October 2018. The electrical energy load of 4330 kWh DH building is supplied by PLTS 333,383 kWh, PLTB 121.07 kWh, and supply of 803.57 batteries. kWh The shortage of electrical energy from the microgrid system is supplied by PLN by 1591.7 kWh and when overproduction, PLN can get energy from the 541 kWh microgrid. Battery charging energy is 1894.38 kWh. The use of renewable energy in the DH building reached 63.24%. Keywords— Microgrid, PLTS, PLTB, Battery

Abstract

Forecasting is the process of estimating a future value using data from the past or data from the present as a reference. Forecasting is a critical component of an organization's short- and long-term planning as a reference for management decision making. Identifying the data pattern in the time series data utilized is a crucial step in identifying the best forecasting approach for the data pattern. The Gray Prediction Model is a forecasting technique that can be used with partial data or a little amount of data. The Grey-Markov forecasting approach may be used to make very accurate forecasts using Udayana University education acceptance data, which is limited, with only five historical data and data patterns classed as horizontal data patterns with modest fluctuations.
