Abstract

Every child has dignity that should be upheld, and every child born must receive their rights without the child asking. The act of neglecting a child is a criminal act, because this act does not reflect the humanistic side of humans themselves and violates the law. For children, legal protection is a priority because children tend not to be able to become complete individuals. Child protection is carried out to create conditions so that every child can fulfill their rights and obligations for the child's natural, physical, mental and social growth and development. Child protection is also an embodiment of justice in a society, so child protection is sought in various areas of state and social life.

Abstract

Perpindahan panas global sangat penting untuk memahami mekanisme variabilitas iklim dalam skala global. Rasio Bowen dapat digunakan untuk menentukan fluks panas laten pada suatu permukaan. Tujuan penelitian ini adalah untuk Mengidentifikasi variabilitas evaporasi di Selat Makassar menggunakan metode bowen ratio dan kaitannya terhadap fenomena ENSO dan IOD dan Mengetahui durasi dari fenomena ENSO (El Nino Southern Oscillation) dan IOD (Indian Ocean Dipole) terhadap perubahan evaporasi di Selat Makassar. Rasio Bowen dihitung dengan membagi nilai sensible heat flux dengan latent heat flux. Setelah mendapatkan nilai Rasio Bowen kemudian akan dicari cross-correlation diantara Rasio Bowen dan ONI (Ocean Nino Index) kemudian ditentukan berapa lama jeda waktu yang diperlukan untuk anomali di Samudera Pasifik berpengaruh ke Selat Makassar. Kemudian Cross-correlation dihitung kembali diantara Rasio Bowen dan DMI untuk melihat efek anomali di Samudera Hindia terhadap Selat Makassar. Data sensible heat flux dan latent heat flux didapatkan dari ECMWF (European Centre for Medium-Range Weather Forecasts) dianalisis dari tahun 1990-2022 dan akan dirata-ratakan perbulannya. Didapatkan hasil penurunan Rasion Bowen dari tahun 1990-2022 yang mengindikasikan evaporasi yang semakin rendah. Klimatologi Rasio Bowen menunjukkan evaporasi mengalami 2 kali puncak di bulan April dan November dengan nilai Rasio Bowen berturut-turut 0,133 dan 0,14. Korelasi silang Rasio Bowen dan ONI menunjukkan hubungan yang kuat dimana nilai R sebesar 0.65 dengan lag 2 bulan. Sedangkan korelasi silang Rasio Bowen dan DMI mendapatkan hasil R sebesar 0.13 dengan lag 1 bulan. Dari hasil penelitian ini didapatkan bahwa ENSO menjadi faktor yang memiliki efek besar terhadap evaporasi di Selat Makassar.

Abstract

Olympiads or academic competitions are one of the forums schools use to measure the quality of learning output provided so far. Olympiads are usually held from district to international levels. However, some students and teachers find it difficult to update or enrich their knowledge in solving Olympiad questions. This results in teachers and students having difficulty when solving Olympiad questions. The strategy that can enhance the material and questions of the Mathematics Olympiad is providing modules of material and Mathematics Olympiad questions and demonstrations of solving Olympiad questions. The PAR (Participatory Action Research) method is the method of implementing this community service. The average value obtained by students was 10.67 out of 100, which means that the initial ability of teachers and students to solve Olympiad questions is still low. Furthermore, 46.7% of teachers and students could not answer a question. Furthermore, the initial ability of teachers and students to use the Olympiad material is still low, namely less than 10%, apart from the number theory material. After mentoring, the average score obtained by students was 22.3 out of 100, which means that the initial ability of teachers and students to solve Olympiad questions increased by around 11.6%. Furthermore, 26.67% of teachers and students could not answer a question. Moreover, the abilities of teachers and students increased in algebra and combinatorics materials.

Abstract

Mobile robot path tracking is a fundamental problem in control systems and robotics and has been widely utilized as a platform for integrating multidisciplinary concepts in mechatronics education. This study proposes an experiential learning framework for mobile robot control using a PID-based path tracking approach. The framework integrates theoretical control principles with hands-on implementation through the development of a differential-drive mobile robot equipped with reflective sensor arrays and a microcontroller-based control unit. The PID controller is applied to regulate robot motion based on real-time feedback, and its parameters (Kp, Ki, Kd) are tuned experimentally using a structured trial-and-error procedure. Experimental results indicate that the PID controller improves tracking stability and reduces oscillatory behavior compared to proportional-only control. The optimal parameter configuration (Kp=0.8, Kd=0.32, Ki=0.2) achieves stable tracking performance across different trajectory conditions, including curved paths. From an educational perspective, the proposed framework supports experiential and project-based learning by enabling systematic analysis of control system behavior through iterative experimentation. This work provides a practical and scalable approach for integrating control theory and robotic implementation in mechatronics education.

Abstract

This study examines the complex dynamics between Panglima Laot's traditional authority as eleume (sorcery) holders and Islamic law implementation in Aceh's coastal communities, identifying effective harmonization strategies. The research addresses a critical gap in understanding how traditional maritime institutions negotiate their roles amid growing demands from Islamic law, particularly regarding the transformation of eleume practices and ritual adaptations. Previous studies have focused primarily on formal Sharia aspects without examining traditional ritual dynamics, leaving crucial aspects of cultural negotiation unexamined. Using a qualitative approach with ethnographic methods and case studies in Langsa City and East Aceh District, the study involved Panglima Laot, religious leaders, traditional leaders, and fishing communities as informants, using participatory observation, semi-structured in-depth interviews, and document analysis. Results revealed Panglima Laot's significant transformation through the integration of Islamic monotheism and fiqh values into traditional maritime rituals, replacing mantras with Quranic and Hadith prayers. Successful harmonization was achieved through intensive dialogue and local wisdom-based institutional strengthening, with customary institutions mediating between formal authorities and traditional fishing communities. These findings contribute to Islamic law anthropology studies and provide a conceptual framework for harmonizing tradition and modernity in other Indonesian coastal areas.

Abstract

Wind and wave conditions in the Makassar Strait vary strongly with the monsoon and the strait’s geography. This study characterizes the spatial and interannual variability of seasonal relative exposure and evaluates the consistency between ERA5 wind-speed-based and CMEMS significant-wave-height-based indices for 2020–2024. Seasonal climatologies for December–February (DJF), March–May (MAM), June–August (JJA), and September–November (SON) used five equally weighted seasonal years. Each index was normalized to 0–1 with a min–max reference shared across seasons within its dataset and classified into four exposure zones. A higher index indicates stronger wind forcing or higher waves than elsewhere in the domain and period, not coastal hazard or vulnerability. Interannual variability used the mean, standard deviation, and Friedman test; spatial consistency, Pearson and Spearman correlations, MAE, RMSE, class agreement, and Cohen’s kappa. JJA had the highest mean exposure index (ERA5 0.439; CMEMS 0.410), followed by DJF, SON, and MAM, with the highest wind speed (3.758 ± 0.333 m/s) and significant wave height (0.441 ± 0.057 m). Friedman tests indicated seasonal differences in ERA5 wind speed (p = 0.0036), CMEMS significant wave height (p = 0.0056), and Tm−10 (p = 0.0136). The moderate-exposure zone dominated all seasons in both datasets, with higher relative exposure in the southern domain. Spatial correlations between the indices were 0.799–0.909 and class agreement 61.70–78.57%. Agreement is therefore stronger for spatial pattern than for zone classification and varies seasonally: a wind-based proxy can map relative exposure patterns but not assign classes.
