ANALISIS KERUSAKAN DAN PERAWATAN MESIN INVESTMEN CASTING MENGGUNAKAN METODE PREVENTIVE MAINTENANCE OPTIMIZATION (PMO) PADA DEPARTEMEN DIE CASTING PT. MITRAMETAL PERKASA

Indra Prasetia — 2026-06-10

Production machine reliability is a fundamental factor in maintaining operational continuity within the manufacturing industry. PT. Mitrametal Perkasa, specifically in the Die Casting Department, faces challenges due to the high rate of sudden breakdowns in investment casting machines. This condition results in significant downtime and increased operational costs because the current maintenance strategy remains largely reactive. This study aims to analyze machine failure patterns and determine optimal maintenance intervals using the Preventive Maintenance Optimization (PMO) method. Research data were sourced from the 2025 machine maintenance performance reports, analyzed using reliability parameters such as Mean Time To Failure (MTTF) and Mean Time To Repair (MTTR). The results indicate that determining maintenance intervals based on historical data through the PMO approach provides more accurate maintenance schedule recommendations compared to conventional schedules. The implementation of this strategy is expected to enhance machine availability, minimize sudden failures, and optimize long-term maintenance cost efficiency at PT. Mitrametal Perkasa.

This study aims to analyze the condition, efforts, and factors influencing employees’ Work-Life Balance (WLB) at an e-commerce company amid increasing job demands. Adopting a qualitative approach with a descriptive case study design, empirical data were collected from March to June 2026 through participant observation, in-depth interviews, and a comprehensive literature review. Informants were selected using purposive sampling and consisted of one senior staff member and two staff members. Data were analyzed using the interactive model of Miles and Huberman, while data validity was ensured through source and method triangulation. The findings indicate that the employees’ Work-Life Balance at the e-commerce company is generally at a fairly good level, as employees are able to balance their professional and personal roles despite occasional disruptions caused by urgent work demands or increased workloads. Employees actively maintain this balance by prioritizing tasks, limiting work involvement outside working hours, and utilizing their leisure time for physical and mental recovery with their families. The main factors influencing the achievement of Work-Life Balance include individuals’ time management abilities, fluctuating job demands, emotional support from the family environment, and effective communication among colleagues within the company.

. Penelitian ini mengkaji strategi membangun jiwa kewirausahaan di kalangan mahasiswa sebagai upaya menciptakan entrepreneur muda yang inovatif dan bertanggung jawab sosial. Penelitian menggunakan pendekatan kualitatif deskriptif berbasis studi pustaka, dengan pengumpulan data melalui dokumentasi literatur yang relevan—termasuk artikel, jurnal, dan prosiding—yang membahas kewirausahaan di era digital serta pendekatan pendidikan kritis. Analisis dilakukan secara deskriptif untuk mensintesis temuan, mengidentifikasi faktor pendukung dan penghambat, serta merumuskan rekomendasi praktik dan penelitian lanjutan. Hasil kajian menunjukkan beberapa temuan utama. Pertama, mahasiswa memiliki potensi besar untuk menjadi wirausahawan karena lingkungan kampus yang dinamis, akses sumber daya intelektual, dan peluang usaha mikro yang mudah diakses. Kedua, kemajuan teknologi digital (media sosial, marketplace, layanan keuangan digital) membuka peluang besar bagi mahasiswa untuk memulai usaha dengan modal relatif kecil namun jangkauan pasar luas, sekaligus menuntut keterampilan digital dan pemasaran yang memadai. Ketiga, pengalaman praktik langsung melalui pelatihan, magang, inkubator, dan proyek berbasis komunitas terbukti meningkatkan kepercayaan diri, kreativitas, kemampuan manajerial, dan kesiapan menghadapi risiko bisnis. Keempat, kendala utama yang ditemui meliputi keterbatasan modal, minimnya pengalaman praktis, waktu yang terbagi antara studi dan usaha, budaya akademik yang berfokus pada nilai/ijazah, serta kurangnya bimbingan dan akses pendanaan. Selain itu, aspek internal seperti motivasi, kreativitas, dan keberanian mengambil risiko menjadi determinan penting keberhasilan wirausaha mahasiswa.
