As part of the Sustainable Development Goals (SDGs), governments worldwide have committed to improving people's lives to improve the quality of life for all, including the 17 such goals that were agreed upon in 2015 to benefit the human race as a whole. It would be interesting to see how society responds to the SDGs after approximately half of them have been achieved. This public response was analyzed in terms of sentiment. Within the total number of internet users in Indonesia, there are 18.45 million Twitter users. The platform enables anyone to write about anything they are experiencing in their lives, such as what is happening in their environment, what is happening in their education system, what is happening in the food industry, how people feel, and many more. The platform enables anyone to write about anything they are experiencing in their lives, such as what is happening in their environment, what is happening in their education system, what is happening in the food industry, how people feel, and many more. To model the data collected, the researchers used Ensemble Machine Learning Classifiers (EMLC) to model the data by using a machine learning classifier that uses machine learning techniques. The best model in this study is EMLC-Stacking with a data splitting of 80:20 and using SMOTE, which obtains an accuracy of 91%. This accuracy results from a 5% increase compared to when not using SMOTE. From 15,698 tweets, this research found that 47% were positive sentiments, 28% were negative sentiments, and 25% were neutral sentiments. The results that we measured offer hope that there will be a positive trend in the journey of the SDGs until 2030 if these findings are true.

Extracurricular activities in the world of education are a necessity for students to improve students' psychomotor skills. Academic activities in participating in extracurricular activities will help students form creative learning patterns and be able to increase creativity in sports and skills in areas of interest and talent. The problem that occurs at Dimitra is that there is no structure in conveying information and monitoring students when taking part in extracurricular activities at Madrasah Tsanawiyah and Madrasah Aliyah Manarul Huda. The information system implemented in this service is expected to help provide information on student development in extracurricular activities and can be monitored by parents. The method applied in this activity uses the Rapid Application Development (RAD) method and applies WhatsApp technology with the aim of much faster development with better quality. From the results of the alpha testing, it shows that the application can be applied to partners for community service within the Madrasah Tsanawiyah and Madrasah Aliyah Manarul Huda as a medium for information on extracurricular developments.

Perkembangan pemanfaatan ilmu pengetahuan dan teknologi memberikan dampak yang dapat digunakan diberbagai bidang salah satunya Puskesmas. Salah satu pengembangan yang dilakukan puskesmas yaitu mengembangkan untuk meningkatkan kualitas manajemen pelayanan kesehatan dengan menerapkan sistem informasi puskesmas berbasis teknologi informasi. Pencatatan apabila dilakukan dengan cara ditulis pada buku pasien merupakan cara lama yang digunakan. Maka perlu adanya suatu sistem yang membantu untuk memudahkan pencatatan. Metode pengembangan pada sistem informasi yang akan di ajukan ini yaitu dengan metode Waterfall. Menghasilkan Sistem Informasi Rekam Medis yang terintegrasi untuk mempermudah pihak Puskesmas di daerah Kota Banjar dalam mengolah data jika terdapat pasien yang sebelumnya belum pernah mengunjungi puskesmas tersebut maka akan terdapat Rekam Medis. Sistem Informasi mempermudah dalam mengelola data Rekam Medis sehingga tidak perlu mencari catatan yang begitu banyak dikarenakan data nya sudah tersimpan dalam database. Sistem Informasi Rekam Medis terintegrasi maka data pasien akan terlihat di semua Puskesmas yang ada di Kota Banjar. Pengujian dalam penelitian dilakukan dengan tahapan metode System Usability Scale (SUS) mendapat nilai akhir yaitu 73,1 dan Hasil pengujian menghasilkan nilai rekomendasi dalam kategori Acceptable.The development of the use of science and technology has an impact that can be used in various fields, one of which is the Puskesmas. One of the developments carried out by the puskesmas is developing to improve the quality of health service management by implementing an information technology-based puskesmas information system. Recording when it is done by writing it in the patient book is the old way used. So, it is necessary to have a system that helps to facilitate recording. The development method for the information system that will be proposed is the Waterfall method. Producing an integrated Medical Record Information System to make it easier for the Puskesmas in the Banjar City area to process data. If there are patients who have never visited the puskesmas before, there will be Medical Records. The Information System makes it easy to manage Medical Record data so there is no need to search for so many records because the data is already stored in the database. The Medical Record Information System is integrated so that patient data will be visible in all Community Health Centers in Banjar City. Testing in the study was carried out using the System Usability Scale (SUS) method, obtaining a final score of 73.1 and the test results yielded a recommendation value in the Acceptable category.

Human Activity Recognition (HAR) is an interesting research topic, especially in identifying human movement actions focusing on video-based security surveillance. Symptom of an illness from a movement. The use of HAR in this research is the key to better understanding the various semantics contained in the video to find out the pattern of a human movement, especially in sports movements. In this study, a combination of the CNN and LSTM method algorithms was applied by using several variations of the model parameter values on the dropout layer and batch size to convert the pattern in the video into image form to produce a HAR model. Data processing at the convolution layer is used to extract spatial features in the frame. The extraction results are fed to the LSTM layer on each network for modeling the temporal sequence of human movement. In this way, the network on the model will learn spatiotemporal features directly in end-to-end data training tests to produce a robust model. The test data used are 10 sports activities obtained from related research from the University of Central Florida (UCF). The results showed that the performance was quite good, although there were still errors in the classification of sports activities because they had similarities in the movements of the activities carried out. The classification results show a loss value of 0.4 and an accuracy of 0.94. In further research, what needs to be corrected is the loss value which is still high so that several times the test results show an error in the classification of sports activities that have similarities in the movements of the activities.

Practical activities are carried out in an orderly and timely manner and require systematic recording of activities. The implementation of practicum activities takes place in the Siliwangi University laboratory, to create conducive conditions for practicum activities, a system must be able to support academic success. Not only that, due to the COVID-19 pandemic, previous practicum lectures were held offline and campus policy required online learning. These problems can be overcome by building a logbook information system that can record and keep records of laboratory activities automatically. This information system was created using the Extreme Programming system development method. Starting from database design, system design with UML, system development with Visual Studio. NET 2021. This technology can be used by universities for practical activities at the Siliwangi University Laboratory. The application will remind students to complete each activity in each session by displaying notifications in each practicum schedule, rewards, announcements, and other information related to practicum activities. All activities must be recorded in the application. Based on the results of black box testing, the system can run according to the system test design that the response from each student to the application used is 75.68% which can be concluded that the application of virtual assistant is in the interesting category.
