Abstract

This research which is a grouping and mapping system of Puskesmas (public health center) is one solution to obtain information related to areas that have adequate Puskesmas services. With the help of a geographic information system, it is able to describe the state of the Sleman district based on the availability of health centers per sub-district. In a geographic information system, the information produced is in the form of visual images that make it easier for the public to read the information provided. This study uses data from health workers who work in health centers and were grouped first using the k-means method. The reason for grouping them first was to make it easier to map the existing health centers, while the K-means method was chosen because it has a high accuracy to the size of the object, so this algorithm is relatively more scalable and efficient for processing large numbers of objects. In addition, the K-Means algorithm is not affected by the order of objects.

Abstract

The current situation demands the prevention of the spread of the virus, one of which is by wearing a mask and checking the body temperature. This paper serves as a means of detecting the body temperature by using a thermal camera and the mask with a web camera. The camera is the sensor, and a buzzer is an actuator that go off automatically. A mask detection device is a tool that detects visitors who wear masks. It works by detecting the visitor's face using a camera and Open CV or digital image processing. Then, the data will be processed and compared to the one that has been input into the program. This program is able to detect masks and provide warnings if the visitors do not wear masks in a public space. When the body temperature detector detects a visitor of the normal category, which is 36˚C - 37.5˚C, the buzzer does not go off; when the body temperature is higher than 37.5˚C, the buzzer goes off automatically. An error occurred due to the dark conditions, and from the five trials with 100 cm distance, 60% of the trials were successful. Therefore, it was concluded that the testing of the mask detector succeeded with more than 60% success when the lighting was sufficient; and the distance ranged from 100 cm. This system experiment with five experiments on each sample obtained pretty good results. To get good results, the light determination is very influential.

Abstract

The students of grade XI of the Motorcycle Business Engineering of Vocational High School, who have learned productive subject matter in Motorcycle Engineering and Business, often experience difficulties when directly confronted with motorcycle practice media because the components are closed and hidden by the motorcycle's body cover. Therefore, a learning media which is easy to be learned by the students is essential. It means that all components can be observed clearly, and the material can be understood easily, both in theory and electrical practicum of the motorcycle starter system; the students will better understand the theory and assemble the motorcycle starter system circuit. The learning media for the motorcycle starter system is an electrical board with LEDs that can light up continuously or alternately, so it simulate the workings of the motorcycle starter system. In addition, the running LED simulation makes it easier for students to assemble a starter system. It also makes it easy and fast for students to identify, understand how it works, assemble a motorcycle starter system, and later, when facing practical materials in the form of motorbikes, students will be quicker to apply the material that they acquired from the learning media, so that, in practicum, students will work faster and minimize damage to motorcycles.

Abstract

The disturbance of transformers often occurs at the field is named partial discharge. It refers to the spark release in the isolation of internal cavity or surface caused by the potential difference in the transformer isolation. As a result, the quality degradation of isolation material happens. To test it, the researcher employed Dissolved Gas Analysis by Roger's Ratio and Duval Triangle methods. The results demonstrated that transformer GT 10 reached the highest temperature of 417,229⁰C and produced overheating as indicated by paper carbonation and carbon particle formation in the oil (thermal fault 3000C–7000C). Meanwhile, the GT 20 transformer achieved the highest temperature of 169.2307⁰C and the color of paper isolation change to brown (at <300°C). Both transformers were detected getting the failure of partial discharge as the temperatures were more than 150⁰C; in which several gases were formed, including hydrogen and methane gases at around 150⁰C, ethane gas at approximately 250⁰C, ethylene gas at about 350⁰C, and acetylene gas at around 700⁰C. Accordingly, the higher the temperature, the lower the dielectric capacity, where it should function for separating the electrical conductors.

Abstract

Heart disease is one of the deadliest diseases in and is the number one killer in the world so many studies are carried out to contribute to predicting a person's heart disease. This study aims to help create an early heart disease prediction model from the UCI Machine Learning Repository dataset. The method proposed in this study is a deep learning technique that applies an artificial neural network algorithm with a hidden layer technique in making a heart disease prediction model. This research stage found problems in improving the accuracy of the datasets used by dealing with problems in pre-processing data, such as missing data and determining the form of data correlation. The model was then tested through a heart disease dataset and yielded 90% accuracy. With the creation of this prediction model with python programming, it is hoped that in addition to helping to make disease predictions, it can also provide further innovations in data science in the health sector.
