Abstract

This research aims to examine the effect of the avgas-ethanol fuel mixture on the fuel spray temperature. The research was carried out using a pressurized tube which was sprayed into the mock up which was assumed to be an aircraft combustion chamber with a pressure of 2 bar and a distance of 7,73 cm which would later be sprayed using pure avgas, a mixture of avgas and ethanol namely A80E20 and A60E40 then added with a temperature sensor at the end nozzle, center of jet, and impact wall. The spray temperature can result in incomplete combustion and result in higher exhaust emissions and also damage to the engine if it does not match the temperature capacity of the combustion chamber walls. The spray temperature results for the A60E40 fuel mixture are the lowest temperature, namely 25o-18.2oC and knowing that the more fuel is mixed, the lower the temperature of the fuel.

Abstract

The purpose of this literature review is to explore the influence of parenting patterns on character formation towards the discipline of cadets. The parenting pattern applied plays a crucial role in the formation of cadet discipline. Strong discipline is one of the key factors in a cadet's success in facing tasks and challenges. Scientific articles from various sources were accessed and analyzed to identify the parenting patterns that influence cadet discipline. The research results show that a democratic parenting pattern has a positive influence if applied in the family environment. In the context of transportation vocational schools, the application of a democratic parenting pattern can be applied to help cadets build confidence, and develop leadership skills, and independence. Meanwhile, the application of an authoritarian parenting pattern can be done by providing clear rules and firm actions to shape discipline and responsibility.

Abstract

Abstract – Batik is one of the arts and crafts products that are full of customs and culture of the people in Indonesia. The batik art of Kampoeng Batara UKM has existed and developed in the last two years. The limitations of technical facilities are an obstacle to batik production on a mass scale. Through this community service activity, technical support is provided in the form of production facilities for dyeing, boiling and washing media for batik cloth in the form of 10 drums with a capacity of 200 liters. Some of the drums are modified according to production needs with the capacity required by partners. The results of the activity show that the provision of technical support has given partners confidence to increase the capacity of batik products on a larger scale.

Abstract

A mangrove forest ecosystem is a forest that grows and develops in a coastal area, that is, in a marshy land area in a brackish water area. Kedunghasri is the easternmost village, where waste is channeled from upstream to downstream due to lack of discipline on waste management within the community. Through this charity, 500 mangrove trees can be planted to prevent pollution of marine ecosystems. The results of the activities show that planting mangrove trees can raise awareness that mangrove trees are very influential.

Abstract

The increasing complexity of air traffic operations and the high cognitive demands placed on Air Traffic Controllers (ATCs) underscore the critical need to address factors affecting performance and safety. This study investigates the influence of workload and work-life balance (WLB) on safety outcomes among ATCs at Soekarno-Hatta International Airport through a Systematic Literature Review (SLR). This research is motivated by the growing concern over fatigue-related incidents in aviation, particularly in high-density airspace environments. By synthesizing empirical and theoretical findings from peer-reviewed literature, this study explores how excessive workload, rigid shift structures, and insufficient recovery periods contribute to cognitive fatigue, diminished attentional control, and elevated error rates. In contrast, structured WLB interventions—such as optimized shift rotations, mandatory rest periods, and supportive scheduling policies—are found to mitigate fatigue and enhance operational vigilance. However, the applicability of flexible working hours in ATC settings is constrained by the operational and regulatory frameworks of the aviation industry, particularly the standards set by the International Civil Aviation Organization (ICAO). This study contributes to the discourse on aviation human factors by advocating tailored fatigue risk management strategies and institutional support mechanisms to improve ATC well-being and ensure sustained aviation safety performance

Abstract

Safety culture in aviation training is fundamentally shaped by the interpersonal and instructional behaviors of flight instructors. Instructors not only deliver technical content but also model risk awareness, communication norms, and emotional discipline that shape how student pilots internalize safety values. This literature-based analysis focuses on flight training practices at API Banyuwangi and identifies three core mechanisms that drive safety culture development: instructor competence, leadership style, and institutional reinforcement. Competent instructors who demonstrate reflective pedagogy and consistent behavioral modeling are shown to foster higher levels of psychological safety and long-term risk accountability among trainees. Moreover, institutions that integrate safety objectives across curricula, performance evaluations, and infrastructure further amplify these effects. The synthesis highlights that effective safety education emerges from the convergence of individual instructional capacity and organizational alignment. Embedding safety as a shared ethos rather than a procedural obligation requires intentional design at both the pedagogical and institutional levels.

Abstract

Pengabdian Kepada Masyarakat (PKM) ini dilaksanakan dengan tujuan untuk meningkatkan ketahanan ekonomi pelaku Usaha Mikro, Kecil, dan Menengah (UMKM) yang berada di wilayah pesisir Desa Blimbingsari melalui kegiatan pavingisasi. Permasalahan utama yang dihadapi mitra adalah akses jalan yang buruk menuju lokasi usaha, terutama saat musim hujan, yang menyebabkan terganggunya mobilitas barang dan pengunjung, serta menurunnya daya tarik kawasan sebagai destinasi wisata. Kondisi ini berdampak langsung pada menurunnya pendapatan UMKM dan berkurangnya stabilitas ekonomi masyarakat pesisir. Melalui pendekatan partisipatif, kegiatan pavingisasi dilakukan di jalur strategis yang menghubungkan area usaha dengan jalur utama dan titik kunjungan wisata pantai. Kegiatan ini melibatkan masyarakat setempat secara aktif dalam perencanaan, pelaksanaan, dan perawatan infrastruktur yang dibangun, serta didampingi oleh tim pengabdian dari perguruan tinggi. Selain pembangunan fisik, kegiatan ini juga disertai dengan pendampingan kepada pelaku UMKM terkait pentingnya infrastruktur pendukung dan peran lingkungan usaha yang tertata dalam menarik pelanggan. Hasil kegiatan menunjukkan bahwa pavingisasi memberikan dampak positif terhadap peningkatan aksesibilitas, kenyamanan lingkungan usaha, dan jumlah pengunjung ke lokasi UMKM. Selain itu, kegiatan ini juga memperkuat kolaborasi antarwarga dan menumbuhkan kesadaran kolektif mengenai pentingnya menjaga infrastruktur publik sebagai bagian dari strategi ketahanan ekonomi lokal. PKM ini diharapkan menjadi model pemberdayaan masyarakat pesisir berbasis infrastruktur mikro yang dapat direplikasi di wilayah lain dengan karakteristik serupa.
