Abstract - To enforce traffic regulations on the highway, police officers face obstacles in monitoring the use of seat belts on cars because cars on the highway are always on the move and almost all cars use window film to avoid the heat of the sun entering the car. Based on the above problems, the authors build a software that can monitor or detect drivers wearing seat belts or not with Microsoft Visual C # 2010. To monitor the use of seat belts, digital cameras are used to conduct image acquisition to be processed by computers. . Furthermore, the image is studied by a system using the Back Propagation Neural Network (BPNN) Artificial Neural Network method as the image of the driver using a seat belt. To make a detection, the test image is input that is the same size as the training image. The test results obtained the level of accuracy for image acquisition with a distance of 1 meter with a similarity using a seat belt with a maximum value of 9% and a degree of similarity without a seat belt of less than 4%.

Abstract - The electricity subsidy program is one of the poverty reduction programs by providing electricity subsidies to poor and disadvantaged households paid by the Government of Indonesia to PT. PLN (Persero). At PT. PLN (Persero) Area Rantau Prapat Rayon Tanjung Balai which is located on Jl. General Sudirman has a problem that is faced, namely regarding the subsidy budget, it turns out that there have been many wrong targets, most of the subsidy funds have fallen to economically capable people. The government applies the electricity subsidy policy on target, subsidies must be really enjoyed by poor people. To provide electricity subsidies to poor households and poor households, both humans and agencies cannot be separated from information technology systems. This system is usually called a decision support system that is designed to assist in making a decision where no one knows exactly how the decision should be made. The problem of decision-making systems using fuzzy logic systems is very suitable for definite reasoning or estimation, especially for systems with difficult mathematical models and inappropriate data to get a definite decision.

Abstract - The student president is a student leader who aims to mediate students with the rector. Every year a student presidential election will be held. To carry out the elections, of course, they must have candidates as candidates. To become a candidate, the committee selects candidates based on the conditions that have been determined. The selection is done manually. However, candidates come from different faculties and departments which result in all its limitations, the committee will have difficulties and it will take a relatively long time to determine the candidates. Therefore, building a decision support system using the Sugeno fuzzy method to determine student presidential candidates is a good idea. This study aims to design and implement a decision support system with fuzzy Sugeno method, to facilitate the committee in working. This study uses a library research method. Where the source of information is obtained from books, journals, and others. To design a system created using UML. Based on system design, implementation and testing, the conclusion is that a decision support system with fuzzy sugeno method can determine student presidential candidates. The system built can be used as an alternative in selecting student presidential candidates because it can facilitate the committee in processing data to make decisions.
