Peningkatan kebutuhan energi nasional membuat industri minyak dan gas menjaga keandalan peralatannya. Gas Turbine Compressor (GTC) Centaur 50 di PT. XYZ merupakan salah satu peralatan vital dalam operasi produksi, sehingga diperlukan metode tepat untuk menjaga keandalannya. Metode Reliability Centered Maintenance (RCM) memiliki prioritisasi jenis perawatan yang tepat. Analisa keandalan menggunakan perhitungan kuantitatif dari data handbook OREDA (Offshore Reliability Data), manual book GTC Centaur 50, dan data aktual lapangan. Berdasarkan hasil analisa pendekatan Failure Mode Effect Criticality Analysis (FMECA) dan perhitungan Risk Priority Number (RPN) komponen utama penyebab kegagalan yang dibuat dalam diagram pareto, maka terdapat 20% kegagalan fungsi terbesar (27 kegagalan fungsi). Serta 26 kegagalan fungsi tambahan dari tim maintenance lapangan. Sistem perawatan GTC di PT. XYZ digolongkan dalam 14 sub-system, dimana sub-system tersebut kegiatan perawatannya minimal per 8000 jam berdasarkan RCM II Decision Worksheet yang meliputi 134 program perawatan (scheduled on condition monitoring, scheduled restoration, scheduled discard, failure finding, run to fail). Berdasarkan pendekatan Maintenance Value Stream Mapping (MVSM) dengan siklus plan-do-check-action (PDCA) pada siklus do terdapat Non Value Added pada “eksekusi pekerjaan”. Dengan merekomendasikan mempersingkat menjadi maksimal 48 – 72 jam dengan utilisasi man power lapangan. Sehingga dengan durasi lebih pendek maka LPO (Loss Production Opportunity) dapat diminimalisir.

This study aims to analyze the influence of organizational culture, leadership style, and compensation on employee performance. A strong organizational culture can create a conducive work environment, increase motivation, and strengthen employee commitment to company goals. An effective leadership style also plays an important role in motivating employees to achieve their best performance, by providing clear direction and creating a mutually supportive relationship between leaders and team members. Fair and competitive compensation not only serves as a reward for achievement but also as a tool to retain the best talent in the company. This study uses a qualitative approach with a library research method using journal literature reviews, where data is collected through journal reviews in various industrial sectors. The results of the analysis show that organizational culture, leadership style, and compensation have a significant influence on employee performance simultaneously. Individually, organizational culture and compensation are proven to have a stronger relationship to performance improvement, while leadership style also has a significant impact at a lower level. This research provides insight for companies in designing managerial strategies to improve performance through effective management of organizational culture, leadership style, and compensation systems.

This study is aimed at examining enterprises model and analysing risk level of Palm Sugar in Rejang Lebong Regency. Risk Analysis involve nira harvested, nira processed, palm sugar production, and palm sugar prices received by producers. Twostages cluster sampling method is used to determine research areas, i.e, subdistrict of Sindang Kelingi and Selupu Rejang based on the numbers of firms. Using similar critirea, two villages are selected, i.e, Air Meles Atas and Sindang Jati. From those villages, then, 86 palm sugar producers are selected using Simple Random Sampling. Descriptive analysis is applied to describe entreprises model of palm sugar industries while risks is analysed using its varians, standard deviation, and minimum level of production as proposed by Maryam and Suprapti (2008). The research shows that all palm sugar industries in this regency can be categories as home industries with average production scale of 11.58 kg per process in rainy season and 11. 54 kg in dry season. Palm sugar producers use their own capital to produce palm sugar and borrowed to palm sugar village merchants when they need. From risk analysis, the study finds that palm sugar producers will face higher risk in term of nira harvested and processed, and production in dry season, except in term of price received which is higher in rainy season. Over all, palm sugar producers will not face risk significantly both in dry and rainy season.
