Abstract

Life expectancy is defined as information that illustrates the age of the death of a population. Life expectancy is a general picture of the state of a region. If the infant mortality rate is high, then the life expectancy in the area is low. And vice versa, if the infant mortality rate is low, the life expectancy in the region is high. Life expectancy is also a benchmark for government actions in improving the welfare of society and the human development index. For this reason, it is necessary to group life expectancy data to make it easier to determine the provinces with high, middle, and low life expectancy. The results of cluster testing using the silhouette score method showed that two subjects had a low silhouette score level, which caused the cluster value to be less than optimal, namely East Java  & Gorontalo. The clustering results found that the cluster was divided into 3, namely cluster 1, with a high level of life expectancy consisting of 10 provinces, namely East Java, Riau, North Sulawesi, Bali, North Kalimantan, DKI Jakarta, West Java, Central Java, East Kalimantan and Special Region of Yogyakarta. Cluster 2 has a level of middle-life expectancy consisting of 18 provinces, namely Gorontalo, North Maluku, Central Sulawesi, South Kalimantan, North Sumatra, Bengkulu, West Sumatra, Central Kalimantan, Aceh, South Sumatra, Banten, Kep. Riau, South Sulawesi, Kep. Bangka Belitung, Lampung, West Kalimantan, Southeast Sulawesi and Jambi. Cluster 3, with a low level of life expectancy, consists of 6 provinces, namely West Sulawesi, Papua, Maluku, West Papua, West Nusa Tenggara, and East Nusa Tenggara.

Abstract

Earthquakes are natural disasters with significant impacts on people and the environment, so effective methods for prediction are needed to improve preparedness and risk mitigation. This study analyzes the performance of three algorithms Support Vector Machine (SVM), Naïve Bayes, and K-Means in predicting earthquakes in Indonesia using a dataset containing 4,645 historical data from BMKG processed through preprocessing, data separation, analysis, and performance evaluation with RapidMiner tools. The results show that SVM has the best performance with 99.87% accuracy, 99.83% precision, and 95.61% recall, making it highly relevant for earthquake prediction. Naïve Bayes achieved 90.31% accuracy and 95.08% recall, but the low precision (57.24%) shows the limitations of this model. K-Means successfully clusters earthquakes into two categories: small (3,661 data) and large (55 data) earthquakes, with a Davies-Bouldin Index value of 0.579, reflecting good clustering quality. Based on these results, SVM is recommended as a superior earthquake prediction model, while Naïve Bayes and K-Means are more suitable for additional analysis. This approach confirms the potential of machine learning algorithms in supporting future earthquake risk mitigation.

Abstract

Learning in e-commerce development is vital in helping understand digital business concepts, especially in overcoming the limitations of conventional learning methods, such as listening, observing, and taking notes. By using the ADDIE model, which includes analysis, design, development, implementation, and evaluation, this learning process provides a systematic and comprehensive approach. In this training, you will not only gain theoretical knowledge but also practical skills in modifying and managing e-commerce platforms. This learning aims to be able to understand and carry out the process of creating and managing an online business while stimulating creativity and enthusiasm for entrepreneurship. The results of this learning show that e-commerce development is very effective in facilitating the understanding of concepts and helping link theory to the world of work. Apart from that, the level of satisfaction of the female students was very significant, and they felt more prepared to apply the knowledge they had gained. This training proves that e-commerce development not only provides a better understanding of business but also prepares you with relevant skills to face the challenges of an ever-evolving digital world.

Abstract

Pengabdian ini bertujuan untuk membantu Ikatan Pencak Silat Indonesia (IPSI) Cikarang Selatan menyusun bagan tanding turnamen pencak silat sehingga lebih terorganisir dan terintegrasi dengan sistem pendaftaran online yang sebelumnya dilakukan secara manual sehingga sering menyebabkan keterlambatan, kesalahan penempatan peserta, dan jadwal pertandingan yang tumpang tindih. Selain itu untuk memberikan sosialisasi dan pelatihan kepada pengurus dan panitia turnamen pencak silat mengenai tata cara penggunaan kecerdasan buatan (artificail intelligence) untuk membuat bagan tanding yang efisien dengan metode pengacakan sederhana menggunakan aplikasi digital berbasis kecerdasan buatan yang dibuat dengan bahasa pemrograman PHP. Metode yang digunakan adalah sosialisasi dan edukasi pada mitra tentang penggunaan aplikasi, kegiatan menunjukkan bahwa sistem ini dapat meningkatkan efisiensi penyusunan bagan secara signifikan dari rata-rata 60 menit menjadi sekitar 15 menit dengan penghematan waku lebih dari 70%. Selain lebih cepat, tumpang tindih jadwal pertandingan dan kesalahan input dapat dihindari sehingga proses penyusunan lebih akurat dan dapat diandalkan. Bagan yang dihasilkan juga lebih teratur, dan siap dipublikasikan. Keunggulan lain dari sistem ini adalah fitur pendaftaran peserta secara online, yang memungkinkan panitia mengolah data langsung tanpa perlu mengetiknya lagi. Pelatihan yang diberikan kepada pengurus IPSI menunjukkan bahwa peserta cepat memahami sistem dan dapat menjalankannya secara mandiri. Secara keseluruhan, kegiatan ini berhasil mencapai tujuannya dalam membantu pengurus IPSI menemukan cara yang lebih baik untuk mengelola turnamen. Sistem ini masih dapat dikembangkan untuk memasukkan fitur tambahan seperti cetak hasil bagan secara otomatis, pembaruan jadwal secara real-time, dan integrasi laporan turnamen yang lebih lengkap.    Kata kunci: Pencak silat, IPSI, turnamen, digital, AI, PHP, real-time. ABSTRACT This service aims to assist the Indonesian Pencak Silat Association (IPSI) of South Cikarang in compiling a pencak silat tournament bracket so that it is more organized and integrated with the online registration system, which was previously done manually, often causing delays, participant placement errors, and overlapping match schedules. Additionally, it provides socialization and training to the administrators and committee members of the pencak silat tournament on how to use artificial intelligence (AI) to create an efficient match schedule using a simple randomization method with a digital application based on artificial intelligence created with the PHP programming language. The method used was socialization and education of partners on the use of the application. The activity showed that this system can significantly increase the efficiency of charting from an average of 60 minutes to about 15 minutes, with a time saving of more than 70%. In addition to being faster, overlapping match schedules and input errors can be avoided, making the charting process more accurate and reliable. The resulting charts are also more organized and ready for publication. Another advantage of this system is the online participant registration feature, which allows the committee to process data directly without having to retype it. The training provided to IPSI administrators showed that participants quickly understood the system and were able to run it independently. Overall, this activity successfully achieved its goal of helping IPSI administrators find better ways to manage tournaments. This system can still be developed to include additional features such as automatic printing of bracket results, real-time schedule updates, and more comprehensive tournament report integration.
