Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh faktor sumber daya manusia (usia, lama bekerja, dan absensi) terhadap kualitas produk di PT XYZ dengan menggunakan metode regresi linier berganda. Data yang digunakan mencakup informasi dari database karyawan dan jumlah produk cacat dalam proses pengemasan. Hasil penelitian menunjukkan bahwa absensi memiliki pengaruh signifikan terhadap kualitas produk dengan nilai koefisien -3,51264 dan p-value = 0,0236 (p < 0,05). Namun, usia (p-value = 0,6234) dan lama bekerja (p-value = 0,7503) tidak menunjukkan pengaruh signifikan terhadap kualitas produk. Nilai R-squared sebesar 9,58% dan Adjusted R-squared sebesar 5,40% menunjukkan bahwa meskipun faktor-faktor yang diuji memberikan beberapa wawasan, masih terdapat faktor lain yang lebih dominan dalam memengaruhi kualitas produk. Penelitian ini bersifat kontekstual di PT XYZ dan tidak dapat digeneralisasi ke industri lain. Temuan ini diharapkan dapat memberikan kontribusi dalam pengelolaan sumber daya manusia untuk meningkatkan kualitas pengemasan, mengurangi cacat produk, serta memperkaya pengembangan human resource analytics di industri farmasi, sekaligus membuka peluang untuk penelitian lebih lanjut terkait pengambilan keputusan berbasis data.

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.
