Abstract

The construction of transportation infrastructure, such as airports, poses significant challenges in terms of environmental sustainability. Therefore, introducing the concept of Green Supply Chain (GSC) to vocational high school (SMK) students in the logistics field is essential. This community service activity aimed to improve students' understanding of GSC through interactive training and structured evaluation. The implementation method included the delivery of materials, discussions, and pre-test and post-test assessments to measure the effectiveness of the activity. The results showed a significant increase in students' comprehension, with the average pre-test score of 73 rising to 88 in the post-test. The N-Gain score of 0.5556 categorized the training as moderately effective. This activity contributed to equipping SMK students with environmental awareness related to construction practices and supported the integration of sustainability topics into vocational education. The outcomes also indicate that such training has strong potential for further development into more contextual and applicable learning models for vocational students.

Abstract

The construction industry is a major contributor to global carbon emissions, largely due to the use of conventional materials with high thermal conductivity. This highlights the need for environmentally sustainable insulation materials aligned with circular economy principles. As the world’s fourth-largest banana producer, Indonesia generates vast amounts of banana peel waste that can be repurposed as an eco-friendly thermal insulation material.This study evaluates the thermal performance of banana peel-based biocomposite (BP80-PS20) as an insulation material for tropical buildings. The research employed a systematic literature review and numerical simulations using DesignBuilder software on a simplified model of a tropical house. Key parameters analyzed include thermal conductivity, U-value, and R-value, benchmarked against Indonesian (SNI 6389:2011) and international (ASHRAE 90.1-2019) standards. Simulation results indicate that BP80–PS20 significantly improves thermal resistance, reducing wall U-values from 2.97 to 0.68 W/m²K and partition U-values from 1.64 to 0.30 W/m²K, corresponding to an increase of over 300% in R-value. The insulated building maintained indoor temperatures between 24.5°C and 27.2°C, which fully falls within the SNI and ASHRAE comfort zones. These findings confirm that banana peel waste can serve as a sustainable thermal insulation material, enhancing building energy efficiency and promoting green construction practices in tropical climates.

Abstract

This study aims to develop a technically compliant and economically feasible design for a Restricted Security Area (RSA) perimeter fence surrounding Substation 7, the Chiller facility, and the Ground Water Tank (GWT) at Kertajati International Airport. These facilities constitute critical operational infrastructure supporting electricity distribution, terminal cooling systems, and water supply, including fire suppression reserves. Field observations identified the absence of a regulation-compliant perimeter protection system, exposing the utility cluster to unauthorized access and operational risk. The research employed a quantitative descriptive–analytical approach integrating field measurement, engineering design modeling, volume computation, and cost estimation based on the 2024 Majalengka Regional Standard Unit Price. Technical evaluation referred to national aviation security regulations and ICAO Annex 17 principles. A BRC (British Reinforced Concrete) fence system with a total height of 3.20 meters (2.40 m fence body and 0.80 m concertina wire) was proposed. The structural configuration includes reinforced concrete isolated footings, tie beams (sloof), and a bottom plinth beam to ensure lateral stability and anti-climb resistance. The total perimeter length of 313.74 meters ensures complete enclosure of the critical facilities. The estimated total project cost amounts to IDR 509,553,000.00, including VAT. The results demonstrate that the proposed design is structurally reliable, regulation-compliant, and economically justified within a risk mitigation framework. The study contributes a replicable engineering and financial planning model for strengthening airport critical infrastructure protection and enhancing long-term operational resilience.

Abstract

The rapid advancement of digital technology has significantly transformed educational systems, including traditional Islamic institutions such as pesantren. This study aims to analyze the reconstruction of kyai leadership in strengthening the quality of pesantren in the era of digital disruption. A qualitative approach was employed using a Systematic Literature Review (SLR) method, drawing on relevant scholarly sources published within the last decade. Data were analyzed using thematic and content analysis to identify key patterns, challenges, and leadership transformations within the pesantren context. The findings reveal that kyai leadership is shifting from a predominantly centralized and traditional model toward a more adaptive and integrative approach. Major challenges include limited digital infrastructure and low levels of digital literacy among educators and students. At the same time, kyai are increasingly assuming roles as agents of transformation who promote technology-based educational innovation. This study proposes a conceptual model of Digital Kyai Leadership, integrating spiritual, transformational, digital, and collaborative dimensions as a strategic framework for enhancing pesantren quality. The findings underscore the importance of value-based and adaptive leadership in bridging Islamic traditions with contemporary educational demands. This study contributes to the development of Islamic education management and provides practical insights for strengthening pesantren leadership in the digital era.
