<![CDATA[Indramayu is one of the regencies in West Java Province that produces food crop production in the agricultural and plantation sectors. Many people work in the agricultural sector, one of which is by growing vegetables on their land. Planting vegetables on land in the Indramayu area often experiences problems, for example the land used is not in accordance with the type of vegetables grown. Some farmers have difficulty in evaluating land due to their lack of understanding of the land to be planted so that farmers rely on the system of planting habits that they usually do. The wrong land selection can result in energy and financial losses used for maintenance. Vegetables will develop imperfectly, even vegetables can die because of the inappropriateness of the land used. This study aims to assist farmers in determining what types of vegetable crops can be planted on their land using the k-means clustering method. There are 7 data criteria used for processing k-means so that later it can produce output a recommendation of vegetable types that can be planted by farmers according to the criteria they enter into the system. The results of this study produce an expert system that can provide information about vegetables selected according to the criteria selected by each user and with this system, ordinary people can find out how the selection of types of vegetables is practically on the land to be planted with vegetables.]]>

<![CDATA[Technological developments in data security systems in maintaining information security have grown rapidly. Medical record is a document that contains personal data and medical history and medical treatment history of a patient at a hospital. Medical records are sensitive and confidential so that not just anyone can read the information in the patient's medical record. This study aims to secure patient medical record information by encrypting it with caesar cipher cryptography, the name of the patient's disease, then from the results of the encryption, the process of inserting the encrypted information into a digital image uses the least significant bit (LSB) steganography, namely replacing 1 digit behind the binary number in every 1 bit. The results of the study show that the application created is capable of encrypting and encoding patient medical record data information and embedding this information into digital images.]]>

<![CDATA[Predictive maintenance can reduce the risk of sudden transformer failure which causes the risk of plant to stop operating. One of transformer predictive maintenance technique is the Dissolved Gas Analysis (DGA) Test Oil Transformer. The gas is interpreted and analyzed to find out and get conclusions about the health condition and also possible problems in the transformer based on IEEE Standards and IEC Standards. To facilitate monitoring, a Decision Support System for Interpretation of Test Results of DGA Oil Immersed Transformer was created to form a database containing transformer data with the amount of main gas from the DGA test results. Next, decision tree was made using the J48 algorithm. The decision tree simplifying and speed up the decision-making process for recommended actions that are displayed on the system. The system also displays a trending graph of the last transformer test and quickly displays a dashboard of transformer status, i.e. normal, alarm, or danger. Engineer will get notification email if any transformer is in danger status. In addition, the system is able to provide information on possible fault types for each transformer. The benefits of this system are that the health condition of the transformer can be monitored properly and corrective action can be taken immediately on a problem based on the results of the decision support system. This will reduce the risk of shutdown and support the reliability of plant operations.]]>

<![CDATA[Machine learning requires data to make predictions. Data can have a large number of features. The large number of features can cause machine learning models to overfit, increase model complexity, and high computational costs. Feature selection is one method for optimizing machine learning models. Feature selection reduces the number of features used in the learning process. This research proposes a feature selection method using meta-heuristic algorithms. The machine learning model serves as the objective function for the meta-heuristic algorithm. The objective function is evaluated at each iteration to obtain the most influential features in the model. The machine learning models used are Random Forest, k-Nearest Neighbors, and Support Vector Machine. The meta-heuristic algorithms used are Differential Evolution, Flower Pollination, Grey Wolf, and Whale Optimization. The research shows that using meta-heuristic algorithms can improve the accuracy of machine learning models with fewer features. The Support Vector Machine – Differential Evolution scheme has the highest accuracy and uses the fewest features.]]>

<![CDATA[News about covid-19 has become the daily consumption of Indonesian people. The rate of transmission of the corona virus to children in Indonesia is high and requires vigilance for parents and teachers. The lack of awareness of children so that there are still many children playing in groups without paying attention to health protocols. Prevention of covid-19 transmission can be done by providing health education to them to protect children from the covid-19 virus by providing interesting information to early childhood. Providing education through animated videos and games helps capture children's memory related to information provided about preventing covid-19 and increasing body immunity during a pandemic. Interesting education makes children more interested and understand the purpose of the education. This community service activity was carried out by socializing & explaining the introduction of education about covid-19 through animated videos and games. Animated videos about covid-19 are made as attractive as possible by using animated icons and images so that children are enthusiastic in learning to understand the video. In addition, games are also inserted so that children can learn while playing so they don't get bored quickly. The result of this activity was that 90% of the children were active in asking and listening to various things about the covid-19 education that had been given. In addition, children gain new insights about covid education, besides that they can learn through animated videos while playing games so they don't feel bored quickly in participating in community service activities.]]>

<![CDATA[Physics is a subject taught in high schools as per the established curriculum. Teachers often employ traditional teaching methods where students study independently without active participation, leading to boredom and reduced enthusiasm for learning. Physics is frequently perceived as difficult and perplexing by most students, and the utilization of 3D games as a learning tool can help overcome these challenges. This research aims to integrate the Finite State Machine (FSM) algorithm into a 3D game to create a more effective and engaging learning experience for students. The study employs the waterfall method in application development, encompassing stages such as needs analysis, application design, FSM implementation in games, and game testing and evaluation. 3D physics games have been successfully developed and tested for their feasibility. This game serves as an effective means of entertainment and learning, aiding students in enhancing their understanding of physics subjects. According to the results of a questionnaire with 50 respondents, it is evident that this 3D game is quite user-friendly (90%) and possesses a very good user interface (89%). Approximately 78% of respondents stated that their experience in using the game was very good. Moreover, 82% of respondents found that this educational physics game was highly beneficial for learning physics material.]]>
