Abstract:Tanah gambut memiliki karakteristik kompresibilitas yang tinggi sehingga berpotensi mengalami penurunan apabila menerima pembebanan. Penelitian ini bertujuan untuk mengetahui karakteristik tanah gambut, menganalisis besarnya…
rnya penurunan akibat pembebanan saluran drainase pracetak jenis U-Ditch, serta memberikan rekomendasi penerapannya pada tanah gambut di Desa Wonosari Barat, Kabupaten Bengkalis. Penelitian dilakukan menggunakan metode kuantitatif berdasarkan hasil pengujian laboratorium terhadap enam sampel tanah dari dua titik pengujian. Parameter yang dianalisis meliputi Liquid Limit (LL), Plastic Limit (PL), Plasticity Index (PI), angka pori awal (e0), dan Compression Index (Cc). Analisis settlement dilakukan secara teoritis menggunakan persamaan konsolidasi primer Terzaghi pada tiga kondisi pembebanan. Hasil penelitianmenunjukkan rata-rata penurunan meningkat seiring bertambahnya beban, dengan nilai masing-masing 0,0384 m (3,84 cm), 0,0472 m (4,72 cm), dan 0,0572 m (5,51–5,72 cm) untuk kondisi U-Ditch kosong, terisi sebagian, dan terisi penuh. Hasil ini dapat menjadi dasar dalam perencanaan penerapan saluran drainase pracetak jenis U-Ditch pada tanah gambut.
Abstract:Student grade data is personal data that must be protected under Indonesian Law Number 27 of 2022 on Personal Data Protection, yet the rising number of data breaches in the education sector shows that such protection has…
not been optimally implemented. This study implements the 128-bit Advanced Encryption Standard (AES) algorithm combined with Huffman compression to protect the confidentiality and integrity of student grade files in Excel (.xlsx) format, and evaluates its effectiveness through functional, performance, and security testing. The system was developed as a Python desktop application with a CustomTkinter interface, in which the encryption process runs Huffman compression before AES-128, while integrity verification uses SHA-256 hashing. Testing was conducted on seven student grade files from MA Ma'ahid Kudus. The results show that all files were successfully encrypted and decrypted without failure or data alteration, with encryption times of 0.0142-0.0828 seconds and decryption times of 0.0046-0.1417 seconds. The SHA-256 hash values of the original and decrypted files were identical for all samples, yielding 100% recovery accuracy, while the file size increase from padding and header insertion ranged only from 1,092 to 1,101 bytes. The study concludes that the combination of AES-128 and Huffman compression is an effective and efficient solution for protecting student grade data in educational institutions.
Abstract:Sports-related minor injuries are common occurrences in school-based physical education activities, yet literacy regarding appropriate first aid management remains limited among teachers and students. This community service…
ice program aimed to improve knowledge, skills, and preparedness in managing minor sports injuries through a digital-based educational intervention entitled Smart Recovery. The program was implemented among junior high school (SMP) teachers and students in Banyumas Regency, Indonesia, using a participatory and technology-integrated approach. Activities consisted of program socialization, theoretical and practical training on minor injury management based on the RICE principle (Rest, Ice, Compression, Elevation), and the pilot implementation of the Smart Recovery digital application. Program effectiveness was evaluated using pre-test and post-test assessments, practical skill observations, and user feedback questionnaires. The results demonstrated a substantial improvement in participants’ knowledge, with average scores increasing from 62.4 to 88.6, and 95% of participants successfully performing the RICE procedures correctly after training. Furthermore, 92% of users reported that the digital application facilitated their understanding of injury management, while 87% perceived the platform as user-friendly and applicable for physical education learning. The integration of hands-on training and digital learning media proved effective in enhancing sports injury literacy, digital competence, and safety awareness in school settings. These findings indicate that the Smart Recovery program has strong potential as a sustainable and scalable model for promoting sports safety education within junior high schools.

Abstract:Background: Maintaining children's health is a special concern for parents. Changes in children's health conditions are influenced by changes in weather, one of the symptoms that often occurs in children is fever or hyperthermia.…
rthermia. One of the non-pharmacological treatments is by administering Water Tepid Sponge (WTS). Water Tepid Sponge is a combination of warm compress techniques, superficial vascular block compress techniques and wiping techniques. The compression technique is carried out at several points where there are large blood vessels (neck folds, right and left axillary folds, right and left thigh folds) so that vasodilation occurs and then accelerates evaporation and conduction to lower body temperature in children. Objective: To determine the effectiveness of administering Water Tepid Sponge (WTS) to reduce body temperature in toddlers with hyperthermia problems in Panican Village. Method: This study used a descriptive case study with respondents of toddlers with hyperthermia problems. The focus of this case study is the provision of Water Tepid Sponge (WTS) with hyperthermia problems as a nonpharmacological action. This study was conducted in Panican Village for 3 days starting on 23-25 June 2025. Results: After being given Water Tepid Sponge (WTS) for 3 days with 1 meeting within 15-30 minutes using water temperature of 37oC40oC, the child's body temperature decreased, the initial result was 38.7oC and after being given Water Tepid Sponge (WTS) for 3 days, the result was 37.3oC. Conclusion: Providing Water Tepid Sponge (WTS) can reduce body temperature in toddlers with hyperthermia problems in Panican Village.
