Abstract

Teknologi pendeteksi kematangan kelapa sawit telah berkembang pesat. Salah satu tantangan saat ini adalah sulitnya menentukan kematangan secara akurat dengan menggunakan metode manual. Sebuah tinjauan literatur sistematis dilakukan. Artikel ilmiah diperoleh dari jurnal dan dianalisis untuk mengidentifikasi metode yang sering digunakan oleh peneliti. Berdasarkan kriteria eksklusi, 56 makalah dimasukkan dalam analisis. Klasifikasi dilakukan menurut visi komputer dan sensor. Hasil kajian pustaka menunjukkan bahwa metode yang banyak digunakan oleh peneliti adalah model Jaringan Syaraf Tiruan (JST). Sedangkan Near Infra-Red (NIR) merupakan sensor yang banyak digunakan oleh para peneliti karena sensor ini dapat mengukur kematangan buah dengan biaya yang terjangkau. Berdasarkan tinjauan, dapat disimpulkan bahwa visi komputer dan sensor berkontribusi pada pengukuran kematangan yang akurat dan efisien.

Abstract

The palm oil industry is vital to Indonesia’s economy but faces regulatory, environmental, and cost challenges, driving the need for sustainable supply chains. This study examines the impact of Green Supply Chain Management (GSCM) on corporate sustainability performance and the mediating role of Green Innovation. It focuses on Green Procurement, Manufacturing, Logistics, and Packaging. This study a quantitative approach, data was collected from industry specialists through structured questionnaires. The research follows a structured process: problem identification, literature review, hypothesis development, data collection, and analysis using Partial Least Squares Structural Equation Modeling (PLS-SEM). PLS-SEM was chosen for its suitability in handling complex models, formative constructs, and non-normal data, making it ideal for predicting GSCM’s impact on CSP Data from 100 managers across more than 20 companies were analyzed using PLS-SEM with WarpPLS 6.0, which handles non-linear and complex relationships. Findings show GSCM significantly improves economic, environmental, and social sustainability, with Green Innovation mediating economic and social impacts but not environmental ones. The study underscores the need to align GSCM with SDGs for long-term sustainability and offers strategic insights for academics and practitioners.

Abstract

This study analyzes the reasons for waste in the production processes of a paper-based food packaging company in Indonesia and proposes improvement measures to make the operations more efficient. Through the application of Value Stream Mapping (VSM) and Single-Minute Exchange of Dies (SMED), three significant waste categories were charted: product defects (24.74%), unnecessary movements (22.23%), and unnecessary inventory (13.29%). Implementation of SMED successfully reduced the time of tool change from 60.24 minutes to 27.12 minutes, a setup time improvement of 54.98%. Pursuit of labeling system improvement as well as putting in place a Just-In-Time (JIT) inventory practice also played an important role in the reduction of wastes and fast responsiveness. Consequently, Process Cycle Efficiency (PCE) increased from 70.37% to 73.41%, production capacity increased by 1,241 units per cycle, and complaint counts for defective products declined appreciably over a period of six months. These results underscore the actual benefits of Lean methods and underscore the standard for performance excellence for the same pursuit of sustainable operational excellence within the same industry.
