Abstract

Produktivitas alat berat yang berfluktuasi masih menjadi tantangan utama dalam industri pertambangan. Penelitian ini menganalisis penerapan Customer Operation Improvement Program (COIP) dengan kerangka DMAIC (Define–Measure–Analyze–Improve–Control) guna mengoptimalkan kinerja excavator kelas 125 ton di PT XYZ. Penelitian menggunakan pendekatan deskriptif-kualitatif dengan data primer berupa observasi lapangan, wawancara semi-terstruktur, serta skor digital COIP, dan data sekunder berupa log kinerja serta catatan perawatan periode Agustus hingga Desember 2024. Intervensi utama mencakup pelatihan ulang operator, standarisasi SOP, penjadwalan perawatan prediktif, serta penerapan dasbor KPI berbasis real-time. Hasil penelitian menunjukkan peningkatan produktivitas dari 413 menjadi 505 BCM/jam serta penurunan downtime dari 17% menjadi 5%. Penelitian ini membuktikan bahwa COIP, bila diadaptasi ke konteks pertambangan dan didukung sistem digital, mampu menstabilkan kinerja peralatan, menekan pemborosan operasional, dan meningkatkan daya saing perusahaan.

Abstract

As archipelagic countries, Japan and Indonesia's electricity transmission and distribution infrastructures are island-specific. They have limited network areas and face similar risks caused by climate change. Energy conservation through technical approaches to improve energy efficiency is effective in combating climate change and generates more significant economic benefits. This study examines the strategies demonstrated by Japan to improve its energy efficiency and identifies the potential of adopting those strategies in Indonesia. This research includes an in-depth literature review and benchmarking approaches to the two countries' mitigation strategies. The study found that the Japanese approaches, such as the prioritization of strict regulations, extensive use of innovative technology, and solid industrial collaboration, can be adopted to improve energy efficiency in Indonesia. We also identified several obstacles to adopting those approaches in Indonesia, such as policy inconsistencies, limited financial incentives, and fragmented governance. Adopting the Japanese approaches in Indonesia needs clear energy labeling, more integrated energy management in large industries, appropriate electricity pricing, and efficient energy service company (ESCO) schemes.
