International airports are complex work environments with unique occupational health and safety risks. As hubs of intensive transportation activities, airports involve various operations, including flight services, passenger handling, cargo management, and fuel operations. Early detection of fuel leaks is crucial to ensure the aircraft’s fuel system is free from leaks, blockages, or potential fire hazards. This study aims to analyze the causes of fuel leakage and identify appropriate mitigation measures, using observation and literature review methods. The findings indicate that fuel leakage occurring while the aircraft is parked suggests damage to certain fuel system components, such as seal gaskets, sealants, and dome nuts, which may suffer from wear or cracking due to age-related degradation. Such damage poses serious risks, including fire hazards, corrosion to aircraft structures—particularly in hard-to-reach areas like the wings or fuselage—and a drop in fuel pressure that could impair engine performance or cause flight cancellations. To address these issues, thorough inspections of all fuel system components are essential. Additionally, the use of sensors to detect abnormal changes in fuel pressure and flow, combined with rigorous leak testing after repairs, is recommended to ensure operational safety and reliability.

Penggunaan generator set sebagai sumber daya listrik cadangan di Bandara SAMS Sepinggan Balikpapan merupakan langkah krusial dalam menjamin kontinuitas operasional dan keselamatan penerbangan. Penelitian ini bertujuan untuk mengevaluasi implementasi generator set di Gedung Main Powerhouse 1, termasuk analisis teknis, operasional, dan efisiensi energi. Metodologi yang digunakan mencakup pengumpulan data primer melalui observasi lapangan dan wawancara dengan teknisi, serta data sekunder dari dokumen teknis dan laporan operasional bandara. Hasil penelitian menunjukkan bahwa pemasangan generator set mampu menyediakan daya listrik cadangan yang andal selama terjadi gangguan pada pasokan utama, dengan waktu respon yang cepat dan kapasitas yang mencukupi untuk memenuhi kebutuhan kritis bandara. Selain itu, sistem pemeliharaan berkala yang diterapkan berhasil menjaga performa optimal generator set, mengurangi risiko kegagalan operasional. Studi ini juga menemukan bahwa efisiensi energi generator set dapat ditingkatkan melalui pengoptimalan beban dan penggunaan teknologi terkini. Implementasi ini tidak hanya meningkatkan keandalan pasokan listrik tetapi juga mendukung operasional bandara yang lebih aman dan efisien. Rekomendasi dari penelitian ini meliputi peningkatan pelatihan teknisi, pembaruan perangkat keras, dan pengembangan prosedur mitigasi risiko untuk memastikan keberlanjutan pasokan listrik cadangan di masa mendatang.

This study aims to investigate the role of legal socialization at Vocational High School (SMK) Taman Siswa Kisaran in preventing online gambling practices among adolescents, as well as to understand the legal implications that adolescents may face when involved in such activities. The research method employed is a qualitative approach, gathering data through interviews with teaching staff, students, and legal experts, along with observation of the legal socialization activities conducted at the school. The findings indicate that SMK Taman Siswa Kisaran has implemented various legal socialization activities, including workshops, seminars, and extracurricular activities, to enhance students' understanding of the legal consequences of online gambling. However, challenges in the implementation of legal socialization were identified, such as resource constraints and lack of support from relevant parties. Potential legal repercussions for adolescents include criminal penalties, fines, and long-term consequences related to criminal records. Therefore, this study highlights the importance of the school's role in disseminating information about the laws related to online gambling to adolescents, emphasizing the need for greater support from the school, government, and other relevant institutions to enhance prevention efforts. The implications of this research include the development of more effective legal socialization strategies and the necessity for collaborative efforts among various stakeholders to address the issue of online gambling among adolescents. Thus, this study underscores the urgency and relevance of prevention efforts against online gambling practices among adolescents through legal socialization approaches in the educational environment.

The aim of this research is to find out how the basic price of furniture production is determined and constrained by Islamic economics in Taman Rajo District. This type of research is descriptive qualitative with primary and secondary data types. The data collection technique in this research uses observation, interview and documentation techniques, while for data analysis the researcher uses domain, textonomic and componential analysis. The results of the research explain that determining the basic price of furniture production according to Islamic economics in Taman Rajo District is carried out using several methods, including furniture business actors in Taman Rajo District determining or calculating the cost of raw materials used to produce furniture products. Business actors calculate labor costs which are calculated based on the results of the products produced and business actors calculate overhead costs which are costs incurred apart from raw material costs and labor costs in the production process. Obstacles in determining the basic price of furniture production according to Islamic Economics in Taman Rajo District include limited business capital which has an impact on determining production prices because the supply of raw materials is less affordable due to limited business capital for furniture business owners. Apart from that, the obstacle in determining the cost of production is that the strategic market target has not been achieved because the marketing strategy implemented by the business owner has not been maximized so that determining the cost of production is still based on the number of customers who order furniture products.
