Abstract

This study aims to examine the variables that impact the purchasing of disposable diapers by using an enlarged Theory of Planned Behavior (TPB) framework. Two hundred thirty-two people in Surabaya who were familiar with the use of disposable diapers for either infants or the elderly were surveyed online. A quantitative explanatory approach was used to examine this data. Knowledge, Morality, Tradition, and Perceived Risk are new components of the extended TPB model that take into consideration the specific social and cultural context of Indonesia. For this data analysis, we turned to LISREL, which stands for Structural Equation Modeling. The results show that environmental consciousness, understanding, and ethics significantly affect intent, behavior, and result. Some elements that affect the intention to buy include subjective norms and perceived behavioral control; on the other hand, perceived risk and tradition have an adverse effect on these factors. Consistent with the TPB paradigm when applied to one-time use products, these findings highlight the role of moral and cultural factors in determining responsible consumption behavior. Adding more variables to the TPB model has expanded research on industrial and consumer decision-making behavior.

Abstract

PT. Intidaya Dinamika Sejati adalah perusahaan yang bergerak di bidang produksi dan distribusi peralatan industri, dengan salah satu produk utamanya adalah Medical System Vacuum. Studi ini menganalisis permasalahan di Departemen Purchasing terkait proses produksi, dengan mengidentifikasi tantangan utama seperti keterlambatan dalam pembuatan Bill of Materials (BOM) akibat antrean analisis kerusakan serta ketidakefisienan dalam alur kerja dari Sales Order (SO) ke Work Order (WO). Melalui pengamatan langsung,analisis data kegagalan, dan wawancara dengan ahli, ditemukan bahwa waktu produksi normal per unit adalah tiga minggu. Untuk meningkatkan efisiensi, beberapa solusi diusulkan, termasuk digitalisasi dan otomatisasi analisis BOM, optimalisasi pengadaan material melalui kerja sama dengan pemasok, penerapan sistem persediaan Just-In-Time (JIT), serta pemantauan pengiriman material secara real-time. Peningkatan koordinasi antar divisi juga menjadi faktor penting melalui penyederhanaan prosedur, penerapan sistem komunikasi digital, dan pelatihan lintas divisi. Selain itu, untuk mengatasi keterlambatan proyek, diperlukan penjadwalan ulang dengan waktu buffer yang lebih realistis, pemantauan progres secara berkala, dan penerapan analisis risiko secara proaktif. Langkah-langkah ini diharapkan dapat meningkatkan efisiensi produksi, mengurangi biaya dan waktu, serta meningkatkan kepuasan pelanggan, sehingga pada akhirnya memperkuat posisi kompetitif PT. IDS di pasar.
