Abstract

East Luwu Regency is one of the areas in South Sulawesi which has quite large natural resource potential, including mineral resources such as nickel. However, the need for energy to run this industrial sector is a challenge in itself, especially in terms of supplying environmentally friendly energy. This study aims to analyze the potential of renewable energy sources in the region and how their use can reduce dependence on fossil energy sources and environmental pathways generated by the nickel mining industry. The research method used is a qualitative method with Focused Group Discussion (FGD). The results of the study show that the integration of renewable energy sources such as hydroelectric power plants (PLTA) and microgrid infrastructure has great potential in the utilization of nickel resources in East Luwu.

Abstract

In the current rapid development of electronics, the use of Arduino microcontrollers is quite often used in electronic devices, one of which is an inverter. An inverter is a device that can convert direct electric current (DC) into alternating electric current (AC). To get a pure sine wave on the inverter, you can use a technique to modulate the width of the DC wave signal called SPWM (Sinusoidal Pulse Width Modulation), because of its advantages in producing low harmonic disturbances. This method is carried out by combining two square waves as a carrier signal of 10 KHz and a reference signal of 50 Hz. The reference signal and carrier signal are generated with the Arduino Nano microcontroller, by amplifying the SPWM signal using the IR2110 IC, so that it is able to carry out the switching process on the Full-bridge inverter circuit using the IRF3205 Mosfet component and the inverter voltage is increased by a 7V/220V 10A step-up transformer so that expected to produce an AC voltage of 220 V with a frequency of 50 Hz sine wave.

Abstract

This research was conducted to look at the characteristics of current and voltage harmonics in an electric power system loaded with non-linear loads. The inverter is a non-linear load that is widely used in industry, government agencies and households. In theory, the inverter is a non-linear load that can produce harmonics in the electric power system, where the resulting harmonics will flow to the source and to the load. Therefore, this research is to look at the characteristics of harmonics in the power system produced by a three-phase inverter, where this research was carried out in two scenarios. The first scenario is to see current and voltage harmonics under unloaded inverter conditions and the second scenario is to see current and voltage harmonics under loaded inverter conditions. Both of these scenarios are carried out with a varied source voltage. In this study using a passive filter in the form of a single-tuned filter, the simulation results were carried out on conditions before the filter was installed for a THDv value of 38.94% and after the filter was installed it was 27.43%. The difference in value, before installing the filter and after installing the filter is 11.51%. this still exceeds the 1952 IEEE 512 standard, so more than one filter is needed to reduce harmonics

Abstract

Hepatitis is caused by various factors such as viral infections, toxic substances such as alcohol, certain drugs. Many cases of hepatitis have subtle or subclinical symptoms. In Indonesia, the part of East Nusa Tenggara, hepatitis disease is low, because most people who suffer from mild hepatitis C positive in pregnant women are mostly relatively high. More than double the national average of 2.2%. Based on the above problems, an application in the form of an expert system is needed to diagnose liver disorders, one of which is the Bayes theorem method. Bayes' theorem is a method that applies rules relating to probabilities or probability values. Hepatitis patients can die within a few weeks if not treated immediately. It will be used as an initiative to conduct studies on intelligent systems for diagnosing hepatitis. Therefore, this research creates a system that can help doctors treat hepatitis. With the concept of an expert system able to analyze problems and draw conclusions about the transfer of expert knowledge to the system. The results of the studies tested have shown the multiplication result of the highest classification value with the Bayes method and is a type of liver disorder that the patient suffers from.

Abstract

The development of the culinary business in Indonesia in general grows and spreads in various regions and continents in view of the development of the industry in Indonesia, which is increasing day by day. The culinary business is one of the most widely run businesses to date. System design to obtain output is carried out in several stages, namely: forming fuzzy sets, application of implication functions (formation of fuzzy rules), composition of fuzzy rules, assertion (defuzzification). From the results of research that has been done obtained. The input consists of the level of service obtained by real numbers. given is the taste of food with a value of 4 with the domain [4 5]. That is, the variable taste of good food. From the service quality input, a value of 3 is obtained with the domain [3 4]. That is, the service quality variable is quite good. From the input given, the output level of consumer satisfaction is 4.93%, which means that customers are satisfied with the taste of the food and the quality of service provided by the Talasi café.

Abstract

Along with the development of a government institution or agency at this time, the number of assets needed and must be owned by the institution or agency is also increasing. For this reason, assets need good management so that they are easier to monitor and manage. In solving this problem, it is necessary to have a system that assists in managing government assets. An asset management system can assist in managing asset data such as providing transparent and continuous reports. As an approach to designing an asset management system, the author uses direct observation, interviews and literature, created using the programming language PHP Hypertext Preprocessor, Object-Oriented Programing (OOP), system development using the SDLC waterfall method and the database used is MySQL which will be executed on the Windows 10 operating system. In designing the asset management system there are 2 (two) users, namely Admin and Wasapras. Admin and Wasapras have full access rights to the system.

Abstract

Generators are equipment that converts mechanical energy into electrical energy by utilizing the electromagnetic principle in converting its energy, where the mechanical energy can be obtained from prime movers such as diesel engines (PLTD), hydropower (PLTA), gas power (PLTG). , geothermal (PLTPB). Frequency can also be used as a measure of the instantaneous balance between the real power (MW) consumed by consumers (load) and the real power supply from power plants. Setting the excitation current given to the generator so that the generator produces a voltage of 220 volts. electrical systems, generators and components connected with a complete interconnection system to connect several generators and consumers. To supply power from generators to consumers, system reliability is needed, where one of the requirements for an electric power system is said to be reliable if it fulfills the requirements for generating system reliability such as voltage and frequency values, especially in terms of frequency must be within the specified limits (1 % of the standard frequency), where the standard frequency in Indonesia is 50 Hz.
