Abstract

Background: The agricultural sector in Indonesia, contributing 13.7% to GDP and employing 30% of the workforce, is critical to the nation's economy. Despite its importance, the country's participation in the agricultural global value chain (GVC) faces persistent challenges, particularly in advancing agro-processing and integrating into high-value production. Purpose: This study analyzes Indonesia's GVC position and participation from 2007 to 2021, using the UIBE GVC Index and ADB ICIO data.Design/Methodology/Approach: Descriptive statistics and linear regression methods are used to assess Indonesia's forward and backward GVC participation compared to that of 62 other countries worldwide.Findings/Result: Findings reveal significant declines in Indonesia's backward participation, reflecting progress toward self-sufficiency, yet limited participation in complex forward and backward linkages underscores deficiencies in technological infrastructure and value-added exports. Moderate engagement in simple forward linkages highlights the need for targeted investments to boost competitiveness. Strategic interventions in infrastructure, advanced inputs, capacity-building, and global collaborations are essential for strengthening Indonesia's agricultural GVC role. Conclusion: To enhance GVC participation, Indonesia must address technological, infrastructure, and policy gaps. Strategic investments in agro-processing, advanced inputs, supply chain modernization, and international partnerships are critical to boosting competitiveness and export performance. Originality/Value (State of the Art): This study provides comprehensive insights for policymakers and stakeholders, emphasizing innovative strategies to enhance Indonesia’s global agricultural presence and achieve sustainable growth. Keywords: Agriculture, GVC Position, GVC Participation, Global Value Chain (GVC), UIBE GVC Index.

Abstract

This study analyzes power losses due to load imbalance and the calculation of losses in distribution transformers at the Merauke City Customer Service Unit (ULP). The results show that most distribution transformers on the Angkasa, Bampel, Parako, Kompi, and Ermasu feeders experienced load imbalances exceeding the 20% tolerance limit according to SPLN D3.002-1:2014 standards, contributing to increased neutral currents and power losses, particularly in transformers with heavy loads and uneven phase distribution. After phase current balancing using ETAB 19, significant reductions in neutral current and losses were observed, with transformer efficiency increasing by an average of 2-5% per unit. A feeder-based, data-driven balancing strategy, involving the redistribution of load from dominant phases to deficit phases along with regular monitoring, proved effective in improving distribution system efficiency, extending transformer lifespan, and enhancing voltage quality for customers. These findings provide an operational basis for PLN ULP Merauke to prioritize distribution network improvements, maintain a minimum bus voltage profile of 93–95%, and reduce operational costs through regular load balancing.

Abstract

Pada tahun 2025, Unit Pelaksana Transmisi Duri Kosambi dan Pulogadung bertanggung jawab atas pengoperasian 157 trafo tenaga dan 905 trafo arus di 54 gardu induk. Meningkatkan Keandalan Sistem Transmisi: Dengan memastikan ketersediaan material cadang yang memadai, diharapkan gangguan pada trafo dapat diminimalkan, sehingga meningkatkan keandalan sistem transmisi listrik. Mengoptimalkan Pengelolaan Inventori: Penelitian ini bertujuan untuk membantu Unit Pelaksana Transmisi dalam mengelola inventori material cadang secara efisien, baik dalam hal jumlah maupun biaya yang diperlukan, guna mendukung operasional yang lebih optimal. Analisis Deret Waktu (Time Series Analysis): Untuk memodelkan pola kegagalan dan permintaan material cadang dalam periode tertentu, sehingga dapat memprediksi kebutuhan material di masa mendatang. Pendekatan Keandalan (Reliability Approach): Pendekatan ini digunakan untuk mengukur keandalan sistem berdasarkan tingkat kegagalan dan waktu tunggu material cadang, guna memastikan ketersediaan material yang sesuai dengan kebutuhan yang dihadapi. Trafo Tenaga: 4 unit dengan tingkat kegagalan (λ) sebesar 0,0264 dan waktu pemulihan (β) sebesar 0,3541. Estimasi biaya minimum yang diperlukan adalah sebesar Rp21.345.844.706, dengan tingkat keandalan 94,08%.Trafo Arus: 2 unit dengan biaya minimum sebesar Rp80.463.294 dan tingkat keandalan 96,17%. Hasil penelitian ini diharapkan dapat meningkatkan efisiensi dalam pengelolaan material cadang dan memberikan kontribusi positif terhadap keandalan sistem transmisi. Dengan adanya sistem pengelolaan material cadang yang lebih baik, gangguan akibat kegagalan trafo dapat diminimalkan, dan waktu downtime dapat dikurangi, sehingga operasional gardu induk dapat berlangsung lebih stabil dan efisien.
