As technology advances, the development of equipment used by humans is increasing and most of the equipment produces unwanted sounds that cause noise. To overcome this, an alternative material for soundproofing is needed which is relatively cheap and easily available in the community by using marble powder as a polyurethane mixture in soundproof panels. The purpose of this study was to determine the effect of the sound absorption coefficient value and to determine the relationship between the frequency of the sound source and the sound absorption coefficient of acoustic materials using marble powder mixed with polyurethane in different compositions. The sound absorption test in this study was carried out using a two-microphone impedance tube and has a frequency limit of 125 Hz - 4000 Hz, variations in the mass composition of marble and polyurethane powder 1: 1, 1: 2 and 1: 3 with a thickness of 5 cm, 3cm and 1 cm. Then the test results of the 1: 1 test specimen, the lowest sound absorption coefficient value was obtained 0.10 0.73 cm-1 at a thickness of 1 cm with a frequency of 4000 Hz and the highest was 0.73 cm-1 at a thickness of 5 cm with a frequency of 125 Hz, the test results 1: 2 test specimen, the lowest sound absorption coefficient value is 0.29 cm-1 at a thickness of 5 cm at a frequency of 4000 Hz and the highest is 0.67 cm-1 at a thickness of 5 cm at 250 Hz, then the test results of the test specimen are 1: 3 values The lowest sound absorption coefficient was 0.24 at a thickness of 1 cm at a frequency of 4000 Hz and the highest was 0.71 at a thickness of 5 cm at a frequency of 250 Hz. For the comparison of the sound absorption coefficient values ​​based on the composition and thickness, the lowest and highest sound absorption coefficient values ​​are found in 1: 1 specimens with a thickness of 1 cm and 5 cm with the best sound absorption coefficient values ​​on average at a frequency of 500 Hz, but in material 1:2 and 1:3 obtained the sound absorption coefficient values ​​are in between on the grounds that the thicker the material, the higher the sound absorption coefficient value. Thus it can be concluded that the polyurethane composite material mixed with marble powder can be used as a sound absorbing panel material, especially in a 1: 1 composition

Dengue Hemorrhagic Fever (DHF) is still a serious problem in Banda Aceh City. The grouping of dengue disease distribution areas can use data mining techniques through the K-Means Clustering Algorithm by involving several factors that influence it such as population density, rainfall, air humidity and temperature. The purpose of this study is to try to create a distribution cluster group that is included in the high category (C1), medium (C2), and low (C3) in 9 sub-districts in the city of Banda Aceh. The data used in this study are secondary data during the period 2010 to 2017, which includes population density data obtained from the Banda Aceh City BPS office, rainfall, humidity, temperature were obtained from the BMKG Indrapuri Aceh Besar office and data on dengue cases were obtained from the Banda Aceh City Health Office. The results showed that up to 4 iterations of K-Means Clustering was good enough for the classification of dengue case data. The high cluster group (C1) is Baiturrahman, Kuta Alam and Syiah Kuala sub-districts, the medium cluster group (C2) is Jaya Baru, Banda Raya and Ulee Kareng sub-districts, then the low cluster group (C3) is Meuraxa and Kuta Raja.

Traffic problems become very important to minimize the number of accidents. Recorded in 2017, the death toll from accidents reached 703 people. While in 2018 503 people died or fell by 28%. This figure is considered to be the third largest killer, under coronary heart disease and tuberculosis / tuberculosis. Among several causes of accidents such as against the flow of traffic, stops on the road, pedestrians and speeds that are too low compared to other vehicles. Even though the traffic signs are already installed. The low level of awareness of road users will increase the number of accidents. A detection system for potential accidents is needed to reduce the risk and can be used for the investigation process if an accident occurs. The application of a traffic accident prediction system will be a solution to provide a warning of potential accidents. Early detection of incidents is very important to limit consequences such as delays for other road users, lower costs, less time commitment to emergency services, as well as to prevent accidents. Video processing obtained from CCTV installed at intersections, highways, bridges and tunnels will detect pedestrians and oncoming cars automatically. Detection is done by processing each video frame to determine the foreground by the Gaussian mixture models method of each video frame.

Aceh province based on BPS data 2017 has 1.2 million inhabitants have a livelihood as a farmer. Of this amount includes the number of farmers in each of the regency in Aceh. One of district that has a population of farmers that is the South Aceh Regency with a large producer of young plants (palawija), horticulture and plantation crops
 Ruak Village is one of the villages in North Kluet Subdistrict with farmers in the form of coffee, corn, lime and rice. The villagers of Ruak have a livelihood as farmers, both farmers and farmers as well as daily laborers in the local farmers' business. Farmers in the village of Ruak are abundant every year. Based on the data that was successfully obtained during the survey that the farmers in the village of Ruak produced an average yield of 150 tons per year. Every year the village of Ruak lags behind to contribute to the community with the results of farmers produced by the farmers of the of Ruak village.
 The contribution of the farmers of the village of Ruak is not proportional to the celebrations obtained. This causes very high production costs, starting from the cost of plants, buying medicines, fertilizers, tools and daily payment instruments. The cost to plant to harvest is very high. Sometimes not comparable with the selling price of farmers. Prices are not in line with European expectations. Because the market price that has been determined by the parties cannot be negotiated by the farmers and because of the market price.
