Era digital membawa dampak positif dan negatif, termasuk meningkatnya Kekerasan Berbasis Gender Online (KBGO) yang mempengaruhi anak-anak sebagai kelompok rentan. Pengetahuan tentang KBGO bagi guru-guru, tenaga kependidikan, orang tua, dan siswa-siswa termasuk pendampingan bagi korban sangatlah diperlukan. Kegiatan pengabdian masyarakat ini bertujuan untuk memberikan bimbingan teknis bagi guru-guru, dan staff sekolah ramah anak, serta orang tua, dan siswa-siswa SD, SMP, SMA sederajat untuk mencegah dan mengurangi dampak KBGO di Kabupaten Sleman. Kegiatan ini melibatkan 180 peserta dari berbagai latar belakang, termasuk guru-guru, staff, orang tua, siswa-siswa, dan narasumber dari beberapa lembaga terkait. Metode penyampaian materi melalui ceramah dan permainan, serta melakukan evaluasi melalui pre-test dan post-test untuk menilai peningkatan pemahaman peserta. Hasil menunjukkan peningkatan pemahaman peserta dari skor rata-rata 46% menjadi 85%, mencerminkan efektivitas pendekatan yang digunakan. Peserta mengapresiasi materi terkait perlindungan data pribadi dan pengenalan ancaman di media sosial sebagai langkah preventif yang aplikatif. Kendala yang dihadapi mencakup literasi digital yang rendah dan keterbatasan infrastruktur, yang memerlukan perhatian lebih pada program serupa di masa depan. Dengan kolaborasi antara pemerintah, lembaga pendidikan, keluarga, dan masyarakat, diharapkan ekosistem digital yang aman bagi anak-anak dapat terwujud.

This research aims to create a smart feeding system based on the Internet of Things (IoT) to enhance the efficiency of feed delivery in goat farming. The system automatically regulates the feed dispenser according to a predetermined schedule, making it easier for farmers to manage feed. System testing demonstrates its effectiveness in reducing feed delivery time and minimizing waste. The system features an LCD screen that displays the dispenser status, providing real-time information to farmers. This technology also allows for remote monitoring, enabling farmers to manage feed more effectively. The implementation of this system is expected to improve productivity and animal welfare while promoting modernization in farming practices in Indonesia. This innovation is anticipated to offer a sustainable solution to challenges in feed management, providing long-term benefits for farmers and the livestock industry.

Pelatihan Internet of Things (IoT) di SMA Negeri 2 Bantul dilaksanakan sebagai respons terhadap rendahnya literasi teknologi dan keterampilan digital siswa, serta keterbatasan tenaga pengajar dan sumber belajar di bidang IoT. Kegiatan ini bertujuan untuk meningkatkan kompetensi dasar siswa dalam memahami dan mengaplikasikan teknologi IoT melalui pendekatan pembelajaran interaktif, praktik langsung, serta pengembangan proyek mini. Metode pelaksanaan meliputi tahap persiapan, pelaksanaan inti, dan evaluasi, dengan dukungan modul pembelajaran cetak dan digital, video tutorial, serta sesi pendampingan intensif. Hasil evaluasi menunjukkan bahwa 68,3% siswa merasa puas dan 25,5% cukup puas terhadap pelatihan yang diberikan. Pelatihan ini terbukti mampu meningkatkan minat dan pemahaman siswa terhadap IoT, serta memperlihatkan pentingnya sinergi antara sekolah dan perguruan tinggi dalam mendukung transformasi pendidikan berbasis teknologi. Kegiatan ini diharapkan menjadi model pelatihan yang dapat direplikasi di sekolah lain untuk mendorong literasi teknologi sejak dini.

Since the present data expansion and increase are occurring at an increasingly rapid pace, the solution of adding storage space is not sustainable in the long run. The growing need for storage media can be addressed with lossless compression, which reduces stored data while allowing complete restoration. Huffman remains a potent method for data compression, functioning as a "back end" process and serving as the foundational algorithm in applications, among others, Monkey's PKZIP, WinZip, 7-Zip, and Monkey's Audio. Lossless compression of 16-bit audio requires binary structure adjustments to balance speed and optimal compression ratio. The use of a 4-ary Huffman tree (4-ary) branching procedure to generate binary code generation and to insert a maximum of 2 dummy data symbol variables that are given a binary value of 0 with the condition that if the number of MOD 3 data variables = remaining 2, then two dummy data are added, if the result is the remainder 0 = 1 dummy data, and if the remainder = 1 then it is not required. This process effectively maintains a high ratio level while speeding up the 4-ary Huffman code algorithm's performance in compression time. The results show that the efficiency reaches 95.94%, the ratio is 38%, and the comparison is 1/3 of the Level based on calculations, testing, and comparison with other generations of the Huffman code. The 4-ary algorithm significantly optimizes archived data storage, reducing redundancy to 0.124 and achieving an entropy value of 2.91 across various data types.

Penelitian ini bertujuan untuk mengembangkan sistem pakan cerdas berbasis Internet of Things (IoT) yang dirancang untuk meningkatkan efisiensi pemberian pakan di peternakan kambing umbaran. Sistem ini secara otomatis mengatur dispenser pakan sesuai dengan jadwal yang telah ditentukan, sehingga memudahkan peternak dalam manajemen pakan. Pengujian sistem menunjukkan efektivitas dalam mengurangi waktu pemberian pakan dan meminimalkan pemborosan. Selain itu, sistem dilengkapi dengan layar LCD yang menampilkan status dispenser, memberikan informasi real-time kepada peternak. Teknologi ini juga memungkinkan pemantauan jarak jauh, sehingga peternak dapat mengelola pakan dengan lebih baik. Dengan penerapan sistem ini, diharapkan dapat meningkatkan produktivitas dan kesejahteraan ternak, serta mendorong modernisasi dalam praktik peternakan di Indonesia. Inovasi ini diharapkan menjadi solusi yang berkelanjutan untuk tantangan dalam manajemen pakan, memberikan manfaat jangka panjang bagi peternak dan industri peternakan secara keseluruhan.

The development of Internet of Things (IoT) technology offers new opportunities for managing small-scale livestock farming, including goat farming. The partner of this program, the Umbaran Goat Farmers Group in Bantul, still faces several challenges such as a high mortality rate (12%), inefficient manual feeding, limited digital record-keeping, and marketing that relies solely on local collectors. This community service program aims to improve farm productivity through the application of IoT integrated with a digital farm management system. The implementation method included socialization, workshops, theoretical and practical training, and the deployment of technologies such as a web-based farm management platform, RFID identity tags, and an automatic feeding device. A seven-day trial of the automatic feeder resulted in a total feed distribution of 67 kg, with an average of 9.57 kg/day, and demonstrated a feed saving of approximately 12.99% compared to manual methods. The system also successfully maintained feeding schedule consistency twice a day with 100% accuracy. The results indicate improved efficiency, regularity in feeding patterns, and support for digital transformation in livestock management. Therefore, the implementation of IoT in goat farming not only reduces operational costs but also opens opportunities for developing sustainable business models through the integration of digital systems and online marketing.

Smart wheelchairs are an innovation designed to facilitate user mobility while monitoring their condition in real time. One of the main features developed is an integrated weight reading system. However, the accuracy of the sensor is still affected by sitting posture, body position, and surrounding environmental conditions. This study aims to improve the accuracy of the weighing system on smart wheelchairs by applying linear regression analysis as a sensor calibration method. Data collection was conducted under four conditions of use, namely sitting upright, sitting tilted, walking while sitting upright, and walking while sitting tilted, which represent variations in user load distribution. The calibration model was constructed using the average sensor reading data and evaluated using the R², MAE, and MAPE parameters. The results showed a significant improvement in accuracy with an R² value of 1.0000, MAE of 0.0687 kg, and MAPE of 0.111%, as well as a decrease in the average error from ±1.2 kg to ±0.07 kg after the calibration process. The linear regression method proved to be effective in improving the accuracy of sensor readings with light computational calculations. This study also demonstrates the potential of linear regression as an efficient lightweight calibration method for IoT-based medical systems, particularly on devices such as ESP32 or Arduino that display real-time, high-precision body weight measurements.
