Abstract

This study aims to analyze the effect of fabrication and operational failure factors on equipment reliability. In addition, this study also examines the impact of fabrication and operational failure factors on Maintenance Technology 4.0 and the impact of Maintenance Technology 4.0 on equipment reliability. This quantitative research was conducted at the genset product of PT XYZ. The sample of this research is the technicians of PT XYZ spread in branches throughout Indonesia, who have run Maintenance Technology 4.0 in the repair and maintenance of gensets. A non-probability sampling method, namely convenience sampling, was used to get the sample used. The number of respondents was 102 technicians. The analytical tool used is SEM-PLS 4.0. The results prove that the fabrication and operational failure factors do not affect the equipment's reliability. In contrast, the fabrication failure factor does not affect Maintenance Technology 4.0 but differs from the operational failure factor, which influences Maintenance Technology 4.0. Next, Maintenance Technology 4.0 affects equipment reliability. Meanwhile, Maintenance Technology 4.0 mediates the effect of operational failure factors on equipment reliability. In addition, Maintenance Technology 4.0 does not mediate the impact of fabrication failure factors on equipment reliability.

Abstract

Supply Chain Management has become a crucial element in optimizing production and distribution processes. By implementing this concept effectively, companies can achieve operational efficiency, reduce waste, and ultimately reduce production costs. This research aims to explore and analyze the application of Supply Chain Management as a strategy to reduce production costs in a specific industrial context. This research uses a qualitative approach with descriptive methods. The research results show that implementing supply chain management with a focus on cost reduction strategies, operational optimization and sustainable practices has a positive impact on company efficiency and sustainability. The adoption of technology such as inventory management software and transportation management systems successfully automates processes, reduces errors and simplifies supply chain operations. Lean strategies, such as reducing overproduction and lead times, also play a role in improving operational efficiency. Additionally, sustainable practices, including waste reduction and use of renewable energy sources, not only support environmental sustainability, but also result in long-term cost savings.

Abstract

Product quality and production processes are key factors in competing in an increasingly tight global market. This research aims to investigate and develop effective quality management strategies to increase company competitiveness. This research uses a descriptive qualitative approach. The research results show that the development of quality management plays a crucial role in increasing the competitiveness of manufacturing companies. Through the implementation of Total Quality Management (TQM), Six Sigma, and Lean Manufacturing, companies can increase efficiency, reduce waste, and improve product quality. Information technology integration, especially through Quality Management Systems (QMS), helps companies track, measure and improve quality performance more efficiently. Employee training is a key factor in ensuring understanding of quality standards and their role in achieving the company's quality goals. Additionally, the collection and analysis of quality data supports the identification of trends, root causes of problems, and more informed decision making.

Abstract

Ruang siber kini menjadi elemen penting dalam pertahanan modern. Perang Rusia-Ukraina periode 2014-2023 menunjukkan bahwa serangan siber dapat terintegrasi dengan operasi militer untuk merusak infrastruktur vital, mengganggu sistem komando dan komunikasi, serta menyebarkan disinformasi. Di Indonesia, berbagai anomali dan insiden siber terjadi pada instansi strategis, termasuk TNI AD, seperti kebocoran data, serangan malware, website defacement, dan serangan siber lainnya, menunjukkan bahwa ancaman terhadap pertahanan nasional semakin nyata dan perlu mendapat perhatian serius. Oleh karena itu, TNI AD perlu memperkuat pertahanan siber yang adaptif dan berlapis guna menjaga jaringan komando, sistem informasi, dan kesiapsiagaan operasional. Penelitian ini bertujuan menganalisis kesiapan TNI AD dalam menghadapi ancaman siber, mengidentifikasi faktor internal dan eksternal yang mempengaruhi pembangunan pertahanan siber, serta merumuskan strategi yang dapat diterapkan menggunakan kerangka Ends, Ways, dan Means. Metode penelitian bersifat deskriptif kualitatif melalui pendekatan studi kasus Perang-Ukraina periode 2014-2023. Hasil penelitian menunjukkan bahwa TNI AD telah memiliki satuan siber dan infrastruktur teknologi dasar. Namun, masih terdapat tantangan berupa ketimpangan infrastruktur teknologi antar satuan, keterbatasan personel ahli yang tersertifikasi, implementasi regulasi yang belum konsisten, serta koordinasi lintas lembaga yang perlu diperkuat. Pembelajaran dari perang Rusia–Ukraina menekankan pentingnya struktur komando siber yang kuat, SDM profesional, pertahanan berlapis, integrasi C5ISR, serta kemandirian teknologi. Kesimpulannya, pertahanan siber TNI AD masih dalam tahap berkembang dan membutuhkan penguatan organisasi, SDM, infrastruktur teknologi, serta tata kelola. Diperlukan pemerataan kapasitas siber, peningkatan profesionalisme personel, modernisasi infrastruktur teknologi, serta kolaborasi nasional untuk mewujudkan pertahanan siber yang adaptif dan tangguh.
