Abstract

This study aims to analyze and minimize engine downtime on Deutz common rail technology using the Reliability Centered Maintenance (RCM) approach on the TMX-450 Pushback unit which is commonly used in the aviation industry. The analysis uses quantitative data based on downtime data and intervals related to downtime frequency data on injector components which have recorded failure parts with a frequency of 10 times and accumulated downtime of 21 hours. The results of the analysis on downtime values before and after the implementation of RCM are the inspection schedule increased from 5% to 12%, the repair schedule increased from 24% to 49%, the discharge schedule increased from 10% to 19%, and of course no treatment decreased significantly from 61% to 20%. The conclusion is that the implementation of RCM reduces total downtime by 30% and provides an increase in component reliability to 98.8% which shows that RCM is effective in optimizing maintenance scheduling.

Abstract

This study aims to explore the ethical dimensions of halal supply chain management through the utilization of artificial intelligence (AI). In the context of globalization and the rising demand for halal products, understanding how technology can support not only operational efficiency but also adherence to Islamic principles and ethics is crucial. The research examines the integration of AI technology in each phase of the halal supply chain, from the procurement of raw materials to the distribution of final products. Through literature analysis and case studies, the research identifies the ethical challenges faced at each stage, including transparency, accountability, and fairness in transactions. Furthermore, the study offers recommendations for developing ethical guidelines that can guide effective and responsible halal supply chain management practices. Findings suggest that with the appropriate application of AI, companies can enhance consumer integrity and trust while strengthening their position in the rapidly growing halal market. This research contributes to the existing literature on halal supply chain management and emphasizes the importance of incorporating ethical considerations in the digital era.

Abstract

Halal Product Processing (P3H) certification mentoring is a community service activity aimed at helping P3H training participants obtain halal certification in halal human resource competencies. The research was conducted by mentoring halal human resource participants around the KM 72A Rest Area. The method of this activity is PAR (Participatory Action Research) to be able to answer partner problems directly through a combination of knowledge transfer, field practice and ongoing coaching. Mentoring is carried out by training P3H participants by providing pre- and post-tests, as well as creating SiHalal accounts and of course uploading documents to the application. Conducting simulations in conducting halal verification and validation for assisted MSMEs. Training is carried out until P3H participants are eligible to receive certificates. The result of this service is the certification of P3H training participants, which is expected to provide added value for participants and the community around the KM 72A Rest Area and of course, public or buyer confidence in the sustainability of the halal zone at the KM 72A Rest Area

Abstract

This study aims to analyze the influence of User Interface, Perceived Ease of Use, and E-Service Quality on user satisfaction in using the BRImo application. The research employed a quantitative approach by distributing questionnaires to active BRImo users, and the data were processed using Partial Least Square (PLS) with a total of 120 respondents. The results indicate that all three variables have a positive and significant effect on user satisfaction. These findings suggest that an easily understandable interface, ease of use, and reliable digital service quality can enhance the user experience and satisfaction. This study recommends that BRImo continue to strengthen service stability, improve transaction processing speed, and maintain an intuitive interface design to ensure sustained user satisfaction.

Abstract

ABSTRAKPembangunan infrastruktur jalan di Ibu Kota Nusantara (IKN) menghadapi tantangan geoteknik akibat dominasi lapisan clay shale yang bersifat rapuh, berpermeabilitas rendah, dan sangat sensitif terhadap perubahan kadar air. Fenomena slaking dan fissility pada clay shale menyebabkan degradasi kekuatan geser dan meningkatkan potensi kelongsoran, khususnya pada lereng galian, sehingga berimplikasi langsung terhadap keberlanjutan dan keselamatan perencanaan infrastruktur jalan. Penelitian ini bertujuan mengevaluasi efektivitas penggunaan shotcrete dalam meningkatkan stabilitas lereng clay shale pada berbagai variasi kemiringan lereng sebagai dasar teknis penentuan geometri lereng pada koridor infrastruktur strategis IKN. Studi kasus dilakukan pada pembangunan Jalan Bebas Hambatan IKN Paket 6B menggunakan analisis numerik untuk membandingkan kondisi lereng sebelum dan sesudah perkuatan shotcrete. Hasil analisis menunjukkan bahwa lereng tanpa perkuatan memiliki nilai faktor keamanan (Safety Factor/SF) antara 0,6-1,335, yang belum memenuhi kriteria aman sebesar 1,5. Penerapan shotcrete meningkatkan nilai SF menjadi 1,27-1,335, meskipun pada kemiringan tertentu stabilitas jangka panjang masih belum optimal. Temuan ini menunjukkan bahwa perbaikan metode perkuatan saja tidak cukup tanpa pengendalian geometri lereng. Oleh karena itu, kemiringan lereng minimum yang direkomendasikan adalah 1,5:1 hingga 2:1 karena menunjukkan tingkat stabilitas yang lebih baik dan lebih aman untuk kondisi jangka panjang. Secara ilmiah, penelitian ini menegaskan pentingnya integrasi antara metode perkuatan lereng dan pengaturan geometri lereng dalam perencanaan infrastruktur jalan pada kawasan dengan dominasi clay shale, sehingga dapat berkontribusi sebagai dasar teknis dalam mitigasi risiko lereng dan perencanaan infrastruktur jalan berkelanjutan di IKN.Kata Kunci: Clay Shale, Galian Lereng, Shotcrete, Safety Factor, Stabilitas Lereng. ABSTRACTRoad infrastructure development in the Capital City of Nusantara (IKN) faces significant geotechnical challenges due to the dominance of clay shale layers, which are fragile, low-permeability, and highly sensitive to changes in water content. The phenomena of slaking and fissility in clay shale lead to shear strength degradation and increase the risk of slope failure, directly affecting the sustainability and safety of road infrastructure planning. This study aims to evaluate the effectiveness of shotcrete application in improving the stability of clay shale slopes at various slope inclinations as a technical basis for determining appropriate slope geometry within strategic infrastructure corridors in IKN.A case study was conducted on the Section 6B IKN Toll Road construction project using numerical analysis to compare slope conditions before and after shotcrete reinforcement. The results indicate that slopes without reinforcement have safety factor (SF) values ranging from 0.6 to 1.335, which do not meet the required safety criterion of 1.5. The application of shotcrete increases the SF to 1.27–1.335; however, stability under certain slope configurations remains insufficient for long-term safety. These findings demonstrate that reinforcement alone is not adequate without proper control of slope geometry. Therefore, minimum slope gradients of 1.5:1 to 2:1 are recommended, as they provide better stability performance and improved long-term safety. Scientifically, this study highlights the importance of integrating slope reinforcement methods with geometric slope design in road infrastructure planning within clay shale-dominated areas, contributing technical insight for slope risk mitigation and sustainable infrastructure development in IKN.Keywords: Clay Shale, Slope Excavation, Shotcrete, Safety Factor, Slope Stability
