Abstract

Proses administrasi tagihan operasional pembangkit di PLN UIW NTT melibatkan dokumen fisik dan digital, verifikasi berjenjang, serta persetujuan lintas unit sebelum dan setelah pengajuan melalui Vendor Invoicing Portal (VIP). Penelitian ini bertujuan memetakan kondisi proses, mengidentifikasi pemborosan, menetapkan permasalahan prioritas dan akar penyebabnya, serta merancang perbaikan berbasis Lean Office. Penelitian mengintegrasikan Lean Evaluation and Future Improvement (LEFI) sebagai kerangka evaluasi current state dan perancangan future state dengan Lean Improvement Method for Administrative Processes (LIMAP) untuk identifikasi dan pengurangan pemborosan. Analisis menggunakan Value Stream Mapping (VSM), Process Activity Mapping (PAM), klasifikasi pemborosan administrasi, Matriks Dotoli, Root Cause Analysis (RCA) dengan 5 Whys, dan Lean Matrix 2. Current State VSM memetakan 23 aktivitas dengan lead time 67 hari pada skenario hand carry dan 70 hari pada skenario ekspedisi. PAM menganalisis 16 aktivitas dengan lead time 42 hari (hand carry) dan 45 hari (ekspedisi), terdiri atas 2 value added (VA), 4 non-value added (NVA), dan 10 necessary but non-value added (NNVA). Pada 14 aktivitas NVA dan NNVA, waiting (W1), work-in-process/backlog documents (W6), dan under-utilization of people and systems (W8) masing-masing teridentifikasi pada 14 aktivitas; unnecessary motion/searching (W5) pada 12 aktivitas. Matriks Dotoli menetapkan kesiapan dokumen sebelum pengajuan VIP (P4; AIV 23), kesesuaian data dan dokumen pada VIP (P5; AIV 22), dan verifikasi dokumen awal (P2; AIV 20) sebagai permasalahan prioritas. RCA menunjukkan tiga akar penyebab: belum tersedia acuan kelengkapan dan kesesuaian dokumen untuk seluruh tahapan; belum tersedia mekanisme pengendalian data yang menghubungkan penyusunan dokumen dengan input dan validasi VIP; serta belum ditetapkan tanggung jawab penyusunan dan pemutakhiran acuan verifikasi awal. Enam Waste Elimination Action (WEA) dirumuskan. Lean Matrix 2 menetapkan pre-check sebelum persetujuan dan pengajuan VIP sebagai prioritas pertama (WEA-03; ETDm 155), diikuti checklist terpadu kelengkapan dan kesesuaian dokumen sebagai prioritas kedua (WEA-01; ETDm 85). Keenam tindakan disusun dalam Future State VSM sebagai rancangan perbaikan. Penurunan lead time dan pemborosan belum diukur dan perlu diverifikasi setelah implementasi.

The process of administering plant operational bills at PLN UIW NTT involves physical and digital documents, tiered verification, and cross-unit approval before and after submission through the Vendor Invoicing Portal (VIP). This research aims to map process conditions, identify waste, determine priority problems and root causes, and design Lean Office-based improvements. The research integrates Lean Evaluation and Future Improvement (LEFI) as a framework for current state evaluation and future state design with the Lean Improvement Method for Administrative Processes (LIMAP) for the identification and reduction of waste. The analysis uses Value Stream Mapping (VSM), Process Activity Mapping (PAM), classification of administrative waste, Dotoli Matrix, Root Cause Analysis (RCA) with 5 Whys, and Lean Matrix 2. The Current State VSM mapped 23 activities with a lead time of 67 days in the hand carry scenario and 70 days in the expedition scenario. PAM analyzed 16 activities with a lead time of 42 days (hand carry) and 45 days (expedition), consisting of 2 value added (VA), 4 non-value added (NVA), and 10 necessary but non-value added (NNVA). In 14 NVA and NNVA activities, waiting (W1), work-in-process/backlog documents (W6), and under-utilization of people and systems (W8) were identified in 14 activities respectively; unnecessary motion/searching (W5) in 12 activities. The Dotoli Matrix establishes the readiness of documents before the submission of the VIP (P4; AIV 23), the suitability of data and documents on VIP (P5; AIV 22), and verification of initial documents (P2; AIV 20) as a priority issue. RCA shows three root causes: there is no reference for the completeness and suitability of documents for all stages; there is no data control mechanism that links document preparation with VIP input and validation; and the responsibility for preparing and updating the initial verification reference has not been determined. Six Waste Elimination Actions (WEAs) were formulated. Lean Matrix 2 establishes pre-check before approval and VIP submission as the first priority (WEA-03; ETDm 155), followed by an integrated checklist of document completeness and suitability as the second priority (WEA-01; ETDm 85). All six actions are outlined in the Future State VSM as an improvement plan. The decrease in lead time and waste has not been measured and needs to be verified after implementation.
