Abstract

The application of Holomatrix-based information technology advances in the training process as a form of training technology system innovation model to meet the challenges of future tasks, training systems in the military environment, must be implemented in order to be able to provide realistic training in accordance with the description of the actual operating field. In this study, a Holomatrix-based Tactical Combat Simulation Application has been designed that can be used by every member of the various branches of the military, especially the Indonesian Army. The system built and upgraded will provide troops with an overview of modern Holomatrix-based simulations. By using a computer that is able to evoke a three-dimensional atmosphere so that it can display as if it were a physical 3D image. The modern Holomatrix-based simulation will be used to train Tactical Decision Making Procedures (PPKT) and subordinate commanders to map and model yudha so that they can provide an overview of the actual operating field. After testing, it was found that this simulation application can be used as a tactical training tool, where each military branch involved can coordinate properly as it is done in real combat.

Abstract

Information technology has become a major need in everyday life, not only used by individuals but also by a group or organization. Information technology makes all activities more efficient in terms of energy, time and cost. Therefore, the Bandung District Court Class 1A Special participates in utilizing information technology, with the One Stop Integrated Service (PTSP) and Case Search Information System (SIPP) service activities are increasingly efficient in terms of time and cost. However, not all PTSP and SIPP users at the Bandung District Court understand how to use them, so a court service user satisfaction survey is provided to find out whether the performance of the employees is as desired or not. However, the survey tools available at the Bandung District Court Class 1A Special are still in the form of a manual survey box that requires energy and time in processing the data. The results obtained with the development of an information system for this service user satisfaction survey are that the assessment of service users towards each clerk can be known clearly and precisely, besides that the processing of survey reports is more efficient in terms of time and effort, because officers do not need to calculate or manually processing survey data.

Abstract

AbstrakCuaca hujan adalah salah satu unsur iklim yang tinggi keragamannya, membuat pola sebaran hujan disetiap daerah cenderung tidak menentu. Akibatnya informasi akan kondisi cuaca hujan yang diberikan tidak tepat, maka perlu dilakukan prakiraan hujan yang akurat untuk dapat mengantisipasi kondisi cuaca hujan yang tidak menentu. Dengan menggunakan data historis cuaca, serta penggunaan model machine learning dapat diterapkan untuk analisis permasalahan prakiraan hujan. Menggunakan metode random forest dengan komponen hyperparamter e_estimator dan max_depth serta teknik cross validation untuk menghasilkan kinerja model yang optimal. Lalu mengevaluasi kinerja model menggunakan matriks MSE, RMSE dan MAE. Data cuaca BMKG digunakan rentang tahun 2015-2021 dengan jumlah 2557 data yang dimana dibagi menjadi 80% data latih dan 20% data uji. Hasil pengujian model random forest dengan nilai n_estimator : 100, max_depth : None, dan cross validation : 3 menghasilkan kinerja paling optimal. Dengan menghasilkan matriks evaluasi nilai MSE : 0,086,  RMSE : 0,290 dan MAE : 0,186. Serta dalam pengujian aplikasi penentuan kondisi hujan dari 30 kasus data menghasilkan persentase 60%.Kata kunci: Prakiraan Hujan, Machine Learning, Random Forest, Cross ValidationRainy weather is one of the climate elements that has high diversity, making the pattern of distribution of rain in each area tends to be erratic. As a result, the information on rainy weather conditions provided is not correct, it is necessary to make accurate rain forecasts to be able to anticipate erratic rainy weather conditions. Using historical weather data, as well as the use of machine learning models can be applied to analyze rain forecasting problems. Using the random forest method with hyperparameter components e_estimator and max_depth and cross-validation techniques to produce optimal model performance. Then evaluate the performance of the model using the MSE, RMSE, and MAE matrices. BMKG weather data is used for the 2015-2021 range with a total of 2557 data which is divided into 80% training data and 20% test data. The results of testing the random forest model with a value of n_estimator: 100, max_depth: None, and cross-validation : 3 produce the most optimal performance. By producing an evaluation matrix of MSE values: 0.086, RMSE: 0.290, and MAE: 0.186. As well as in testing the application to determine rain conditions from 30 cases of data, it produced a percentage of 60%.Keywords: Rain Forecasting, Machine Learning, Random Forest, Cross Validation

Abstract

The use of Android-based smartphones is currently increasing rapidly. This makes application developers compete to create various applications. Augmented Reality (AR) is an environment that inserts 3D virtual objects into a real environment. AR is a visualization technology that is currently being developed in several fields. Augmented Reality application in the field of education developed in this study is to discuss the solar system for elementary school students. By presenting a good application content, children's imagination will develop positively. Many media explain about the solar system, such as books and videos. However, the development of Augmented Reality-based media is expected to provide its own insights for students. This research has successfully developed a prototype of a product or media in the form of a book that can be interacted with the AR application on an Android smartphone. The discussion in this study will focus on the application side designed, not on the interactive book design side. Regarding the interactive book media, visual displays of books which have been developed. Application testing has been done by directly interacting with students at the elementary school level, then they respond to the questionnaire. The results of these tests are, the level of usability of the application gets a good response and is easy for use by elementary school students

Abstract

Unpredictable climate change poses significant challenges for farmers at Gapoktan Lembang Agri in maintaining sustainable production. To support quick and precise decision-making, a mobile-based monitoring system has been developed, enabling real-time monitoring of greenhouse temperature and humidity through an Android application. This system utilizes IoT sensors to measure environmental parameters, with the collected data transmitted to a server via the internet and displayed directly in the application. The application is designed using Jetpack Compose to ensure a responsive and user-friendly interface, even for users with limited technical knowledge. Firebase is employed as a real-time data management platform to guarantee data accuracy and processing speed. Key features include live monitoring, access to historical data, and data export capabilities for further analysis. The system has been successfully implemented and tested in the greenhouse of Gapoktan Lembang Agri, demonstrating its ability to provide real-time monitoring and accurate data. Feedback from users indicates ease of use and the application's effectiveness in helping farmers respond proactively to environmental changes.
