Abstract

Honey is a key raw material in the traditional medicine industry, processed through a supply chain that involves various stakeholders, such as suppliers, producers, and distributors. However, the management of the honey supply chain faces several challenges, particularly related to waste, including overproduction, excess inventory of raw materials, and defective products. This study aims to develop a framework for reducing waste in the honey supply chain using a Seven Wastes approach to identify problems, conduct root cause analysis through a fishbone diagram, and map the roles and classifications of stakeholders in implementing solutions. The results indicate that waste is caused by various factors, and the roles of stakeholders are classified based on supply chain drivers. This classification includes the management of machine capacity and maintenance at facilities, the implementation of Economic Order Quantity (EOQ), Just-in-Time (JIT), safety stock systems, as well as improvements in raw material quality in inventory management and procurement, and information classification using a forecasting system based on historical data. The implementation of these solutions is expected to optimize supply chain management and reduce waste.

Abstract

Masalah kerusakan mesin yang berulang dan rendahnya efisiensi proses produksi masih menjadi tantangan utama dalam industri manufaktur. Untuk mengatasi hal ini, Total Productive Maintenance (TPM) diterapkan sebagai pendekatan strategis untuk meningkatkan efektivitas dan produktivitas peralatan. Artikel ini menyajikan tinjauan literatur sistematis terhadap 50 artikel ilmiah yang diterbitkan antara tahun 2018 hingga 2024, yang membahas praktik penerapan TPM di berbagai sektor industri. Mayoritas studi menggunakan Overall Equipment Effectiveness (OEE) sebagai parameter utama untuk mengukur keberhasilan TPM, dengan rata-rata peningkatan OEE sebesar 10% hingga 30%. Namun, ditemukan pula berbagai hambatan, terutama pada sektor UKM, seperti keterbatasan anggaran, kurangnya pelatihan teknis, serta rendahnya kesadaran manajemen terhadap pentingnya pemeliharaan. Selain itu, distribusi literatur masih berfokus pada industri skala menengah dan besar, sedangkan penelitian yang fokus pada UKM masih sangat terbatas. Dengan demikian, terdapat peluang besar untuk mengembangkan model implementasi TPM yang lebih sederhana, adaptif, dan sesuai dengan keterbatasan sumber daya UKM. Kajian ini diharapkan dapat menjadi dasar bagi pengembangan kebijakan, pelatihan, dan strategi implementasi TPM yang lebih inklusif dan aplikatif di masa mendatang. Abstract[Total Productive Maintenance Strategy for Improving OEE in Industry: A Systematic Literature Review] The problem of repeated machine breakdowns and low efficiency of the production process is still a major challenge in the manufacturing industry. To address this, Total Productive Maintenance (TPM) is applied as a strategic approach to improve equipment effectiveness and productivity. This article presents a systematic literature review of 50 scientific articles published between 2018 and 2024 that discuss the practice of implementing Total Productive Maintenance (TPM) in various industrial sectors. The majority of studies used Overall Equipment Effectiveness (OEE) as the primary parameter to measure the success of Total Productive Maintenance (TPM), with an average OEE improvement of 10% to 30%. However, various barriers were found, especially in the SME sector, such as budget constraints, lack of technical training, and low management awareness of the importance of maintenance. In addition, the distribution of literature still focuses on medium and large-scale industries, while research focusing on SMEs is still very limited. Thus, there is a great opportunity to develop a TPM implementation model that is simpler, adaptive, and suited to the limited resources of SMEs. This study is expected to serve as a basis for the development of more inclusive and applicable TPM policies, training, and implementation strategies in the future.Keywords: Total Productive Maintenance; Overall Equipment Effectiveness; 8 TPM Pillars

Abstract

In the wake of digital disruption and operational volatility, organizations are compelled to reimagine productivity beyond traditional efficiency. This study introduces an adaptive productivity model by fusing Lean Office practices with Industry 4.0 technologies—specifically IoT, AI, and Big Data analytics—within administrative systems of professional service firms. Using a mixed-methods design, data from 44 participants in a public valuation office were analyzed through multiple regression, revealing a strong predictive capacity (R² = 0.908). Lean Office (β = 0.281, p = 0.016) and Industry 4.0 (β = 0.253, p = 0.020) both demonstrated significant contributions to enhanced productivity and operational responsiveness. Over 93% of respondents observed reduced process time, while 98% acknowledged improved cross-functional collaboration. These results confirm that digital-lean convergence fosters an agile, sustainable, and data-informed working culture. The proposed model offers a future-ready framework for administrative transformation—one that is lean by design, smart by technology, and resilient by culture.

Abstract

Kebutuhan akan sumber energi terbarukan yang berkelanjutan dan ramah lingkungan mendorong penggunaan bahan bakar renewable seperti bahan bakar berbasis fitoplankton sebagai alternatif bahan bakar masa depan. Penelitian ini bertujuan untuk mengkaji model bio-supply chain yang terintegrasi dan optimal dalam mendukung produksi biodiesel tersebut di Indonesia. Pendekatan yang digunakan bersifat kualitatif-deskriptif melalui studi literatur dan analisis konseptual, dengan fokus pada pengembangan sistem rantai pasok yang berkelanjutan, efisien, dan sesuai dengan konteks nasional. Pengelolaan dan optimasi rantai pasok biomassa dianalisis berdasarkan pengambilan keputusan secara hierarkis pada tiga level utama: strategis, taktis, dan operasional. Pada level strategis, pengambilan keputusan jangka panjang meliputi pemilihan konfigurasi rantai pasok, alokasi sumber daya fitoplankton, investasi infrastruktur pengolahan, serta perencanaan kapasitas produksi. Level taktis berfungsi menjembatani strategi dengan operasional melalui pengaturan penjadwalan produksi, pengelolaan persediaan, serta perencanaan distribusi dan transportasi. Sementara itu, level operasional berfokus pada pelaksanaan harian, seperti waktu panen fitoplankton, pengoperasian fasilitas pengolahan, pengiriman biomassa, serta pengendalian kualitas dan penanganan gangguan di lapangan secara langsung. Hasil analisis menunjukkan bahwa penerapan keputusan strategis pada setiap tahap rantai pasok dapat meningkatkan efisiensi sistem secara keseluruhan. Studi kasus pemilihan Teluk Penyu sebagai lokasi budidaya, penerapan sistem kultivasi mixotrofik, dan pemanfaatan teknologi floating photobioreactor (PBR) menjadi contoh strategi yang mendukung produktivitas dan keberlanjutan produksi biodiesel berbasis fitoplankton. Temuan ini memberikan kerangka awal untuk pengembangan sistem bio-supply chain yang terintegrasi di sektor energi terbarukan. Abstract[Bio-Supply Chain Optimization: an Integrated Renewable Energy Supply Chain System as The Implementation of Phytoplankton-Based Biodiesel]The growing demand for renewable and environmentally friendly energy sources has driven the use of renewable fuels such as phytoplankton-based fuels as alternative fuels for the future. This study aims to examine an integrated and optimized bio-supply chain model to support the production of phytoplankton-based biodiesel in Indonesia. A qualitative-descriptive approach was employed through literature review and conceptual analysis, focusing on the development of a sustainable and efficient supply chain system relevant to national conditions. Biomass supply chain management and optimization were analyzed using a hierarchical decision-making framework at three levels: strategic, tactical, and operational. At the strategic level, long-term decisions include the selection of supply chain configurations, allocation of phytoplankton resources, investment in processing infrastructure, and production capacity planning. The results indicate that applying strategic decisions across all stages of the biomass supply chain significantly enhances overall system efficiency. A case study involving the selection of Teluk Penyu as the cultivation site, the application of a mixotrophic cultivation system, and the use of floating photobioreactor (PBR) technology illustrates key strategic choices that support productivity and sustainability in phytoplankton-based biodiesel production. These findings provide a foundational framework for developing an integrated bio-supply chain system in the renewable energy sector.Keywords: bio-supply chain; phytoplankton; biodiesel

Abstract

Patchouli is one of the most valuable export commodities in Aceh. Patchouli oil must meet several qualifications to obtain export eligibility certification, particularly in terms of its environmental impact, where an in-depth analysis of supply chain transparency is necessary, spanning from seed procurement to distribution and entry into the international market. Despite the large potential for patchouli oil production, industries in Aceh face critical challenges related to supply chain transparency and traceability, which undermine efforts to meet sustainability standards and global market requirements. This study analyzes the transparency of the patchouli oil procurement at the PP NILAS Cooperative and the distribution process through PT Ugreen to the buyer, two key institutions in the local value chain. This study use an exploratory case study approach, combining field observation, purposeful sampling, and semi-structured interviews with key stakeholders, including farmers, distillers, intermediaries, exporters, cooperatives, and Non-Governmental Organization (NGO)s. The study found traceability gaps across several elements of the supply chain, limited documentation practices among smallholders, and challenges in aligning local operations with global certification demands. The study highlights the need for supply chain digitalization, inclusive training, and multi-stakeholder collaboration to strengthen supply chain transparency and support sustainable export growth for the Aceh patchouli industry.
