Abstract

Suatu makalah yang diterima atau didapatkan oleh sebuah institusi atau perorangan melalui berbagai sumber merupakan makalah dengan berbagai macam klasifikasi. Misalnya suatu perpustakaan perlu memilah-milah dokumen atau makalah yang diterima ke dalam berbagai kategori. Sebagai contoh suatu makalah dapat merupakan salah satu dari kateogri berikut : Komputer, Elektro / elektronika, Teknik Sipil, Teknik Industri, Ekonomi dan kedokteran. Banyak metode yang dapat digunakan untuk melakukan proses klasifikasi terhadap data, salah satu yang akan digunakan adalah dengan menggunakan metode Naïve Bayessian. Dengan menggunakan metoda ini perlu adanya pembelajaran terlebih dahulu sebelum program dapat digunakan untuk melakukan klasifikasi dokumen / makalah. Pertama-tama program diberi sejumlah input berupa data dokumen / makalah yang sudah diklasifikasikan terlebih dahulu. Setelah cukup banyak data makalah / dokumen untuk setiap kategorinya, maka program sudah siap digunakan untuk melakukan klasifikasi dokumen.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi teknologi siswa SMA dalam bidang telepresence. Telepresence merupakan teknologi penting di era digital karena untuk meningkatkan koneksi antara manusia yang berjarak jauh. Pemahaman terhadap teknologi telepresence sangat penting dan relevan saat ini. Hal ini mengingat peranannya yang terus berkembang dalam bidang pendidikan, kesehatan, industri, hingga komunikasi global. Kegiatan ini melibatkan siswa kelas XI IPA dan XI IPS di SMA Harapan Kasih Bandung, dengan total peserta pengabdian sebanyak 34 siswa. Materi yang diberikan mencakup pengertian telepresence, contoh implementasi dalam kehidupan sehari-hari, serta penjelasan konsep dan implementasinya. Evaluasi hasil pengabdian dilakukan dengan cara memberikan pretest dan post-test yang berfungsi untuk mengukur peningkatan pemahaman peserta pengabdian. Hasil pretest menunjukkan bahwa hanya 5 dari 34 siswa (15%) yang memahami konsep dasar telepresence, dan 9 siswa (26%) dapat menjawab soal dengan benar. Setelah sesi pembelajaran, hasil post-test meningkat secara signifikan: 29 siswa (85%) memahami konsep telepresence, dan 27 siswa (79%) mampu menjawab soal-soal teknis dengan benar. Selain terjadi peningkatan pengetahuan pada siswa, tetapi terjadi juga peningkatan minat siswa terhadap teknologi telepresence.

Abstract

This research is structured to serve as an essential foundation for the development of automated pathfinding systems using Multi-Agent Pathfinding (MAPF) methods within maze environments. Although the Flood fill algorithm has long been recognized and widely used for maze solving by single agents, its application in multi-agent configurations remains limited and requires adaptive innovation. Therefore, this study reviews various related research on MAPF and relevant maze algorithms, proposing modifications to the Flood fill algorithm to enable effective operation in multi-agent scenarios. By expanding the capacity of Flood fill, it is anticipated that the algorithm's advantages, such as low complexity and fast execution, can be harnessed in dynamic multi-agent systems. The primary contribution of this research highlights the significance of implementing a modified Flood fill algorithm as an innovative basis for pathfinding solutions involving multiple agents simultaneously, thereby opening opportunities for more efficient and adaptive robotic and automation system developments

Abstract

Due to the Covid-19 pandemic, some houses of worship have to carry out worship activities online. The obstacle is the human resources in a house of worship who do not yet have the ability or are accustomed to conducting online services. One of the materials that can be taught is the direction of taking online devotional videos. Through this training, it is hoped that the youth at the Vihara Gaya Buddha Bandung organization can add insight and expertise in the creation of online devotional video content. The method used is to combine online and offline training. The online method is used when viewing and learning the needs needed for training activities. The offline method provides hands-on training on how to take videos properly and correctly. The result of the training is an online service production at Vihara Buddha Gaya, Bandung.

Abstract

Swadaya Karya Cibuni Junior High School, Indragiri Village, Bandung Regency, feels the need for a better learning system. One of them is the creation of learning materials that can be used online and offline. Therefore, it will be taught how to make teaching materials using PowerPoint accompanied by videos. Apart from that, it is necessary to use computer applications to make the process of borrowing books in the SMP Swadaya Karya Cibuni library more well-organized. The method used in this training is a direct training system in schools. Maranatha Christian University prepared the training materials and also created a library application that Swadaya Karya Middle School can use. Training is given to teachers at Swadaya Karya Junior High School directly at school. The results of this training were considered suitable by the training participants based on the survey results. The training participants felt that the materials for making these teaching materials were beneficial. In addition, the participants also thought that the library application was easy to use and very useful.
