Abstract

This community service program aims to enhance elementary school students’ understanding and basic skills in STEM-based robotics (Science, Technology, Engineering, and Mathematics) at SD Al-Islah Surabaya, thereby fostering adaptive, creative, and innovative character development in response to the challenges of globalization. The program implementation included the preparation of instructional modules, delivery of theoretical materials, basic programming activities, equipment demonstrations, hands-on practice, and evaluation using observation sheets to assess participant performance. The activity was conducted at SD Al-Islah Surabaya and involved 94 third- and fourth-grade students accompanied by their homeroom teachers. The results indicate that 50% of the students were able to operate the robots they assembled. In addition, students demonstrated high levels of enthusiasm throughout the activities, actively asked questions, and were able to independently attempt and operate simple robotic systems. Overall, the program effectively improved students’ problem-solving skills and critical thinking abilities, while also developing their foundational understanding of STEM concepts and robotics techniques. This initiative is expected to serve as an initial step toward integrating robotics education into the curriculum of the partner school.

Abstract

Dana dan ShopeePay merupakan dua aplikasi dompet digital paling populer di kalangan mahasiswa Indonesia. Meskipun memiliki fitur serupa, keduanya berbeda dalam desain antarmuka, navigasi, dan pengalaman pengguna. Penelitian ini bertujuan mengevaluasi dan membandingkan tingkat kegunaan (usability) kedua aplikasi berdasarkan preferensi mahasiswa menggunakan metode System Usability Scale (SUS). Kuesioner SUS yang berisi 10 pernyataan disebarkan secara daring kepada 45 mahasiswa yang rutin menggunakan kedua aplikasi untuk mengukur kemudahan penggunaan, kenyamanan, dan efisiensi. Hasil menunjukkan Dana memperoleh skor SUS 74,72 dengan kategori "Good", lebih tinggi dibandingkan ShopeePay dengan skor 67,72, yaitu kategori "OK". Temuan ini mengindikasikan bahwa Dana memberikan pengalaman pengguna yang lebih intuitif dan nyaman. Penelitian ini diharapkan menjadi panduan bagi pengembang dalam meningkatkan kualitas antarmuka, serta membantu mahasiswa memilih aplikasi terbaik sesuai dengan kebutuhan.

Abstract

Pengenalan dunia maritim dan jenis-jenis kapal sejak dini penting untuk menumbuhkan minat generasi muda, termasuk anak-anak di panti asuhan yang seringkali memiliki keterbatasan akses terhadap media pembelajaran interaktif. Kegiatan pengabdian masyarakat ini bertujuan untuk mengenalkan berbagai jenis kapal kepada anak-anak di Panti Asuhan Assalafiah melalui pendekatan yang menyenangkan dan mudah dipahami. Pelaksanaan kegiatan menggunakan metode workshop kreatif yang intensif dan berorientasi pada hasil nyata (outcome-oriented). Kegiatan diawali dengan penyampaian materi teori secara singkat dan padat, dilanjutkan dengan praktik langsung (hands-on practice) pembuatan origami kapal serta permainan edukasi di bawah bimbingan instruktur. Evaluasi keberhasilan program diukur melalui analisis komparatif nilai rata-rata kuesioner sebelum (pre-test) dan sesudah (post-test). Hasil kegiatan menunjukkan peningkatan pemahaman peserta yang signifikan mengenai jenis-jenis kapal. Anak-anak panti asuhan menunjukkan antusiasme yang tinggi dan mampu menyelesaikan karya origami dengan baik sesuai instruksi. Metode origami dan game edukasi terbukti efektif sebagai media pembelajaran interaktif dalam meningkatkan pengetahuan maritim anak-anak panti asuhan assalafiah. Program ini disarankan untuk terus dilanjutkan dengan variasi materi maritim lainnya.

Abstract

Internet of Things (IoT)-based positioning has become increasingly important for monitoring and navigation applications. This study proposes a LoRa-based positioning system using Received Signal Strength Indicator (RSSI) measurements filtered by a Kalman Filter. The filtered RSSI values are converted into distance using the Log-Distance Path Loss model, while the target position is estimated through trilateration. Positioning accuracy is evaluated by comparing the estimated coordinates with GPS coordinates obtained from a u-blox NEO-6M module using the Haversine distance. Experimental results show that the Kalman Filter improves RSSI stability and reduces distance fluctuations, leading to more consistent position estimates. However, the positioning accuracy remains lower than GPS, particularly in dynamic environments. Despite this limitation, the proposed system demonstrates the potential of LoRa as a low-power, long-range positioning solution. Future work will focus on adaptive filtering methods to further improve positioning accuracy.
