Abstract

Persaingan bisnis global yang semakin ketat telah menyebabkan terjadinya pergeseran paradigma bisnis dari product-oriented menjadi penyediaan solusi yang memuaskan kebutuhan konsumen. Hal ini telah mendorong kemunculan konsep Product-Service Systems (PSS). Tulisan ini bertujuan untuk membahas hubungan antara konsep desain dan PSS berdasarkan literatur yang tersedia. Berdasarkan kajian yang dilakukan terhadap berbagai literatur tersebut dapat diambil kesimpulan bahwa PSS merupakan konsep yang diyakini sebagai jalan menuju sustainability melalui integrasi antara produk dan jasa dalam penyediaan solusi yang memenuhi kebutuhan spesifik konsumen. Proses desain PSS perlu memperhatikan kebutuhan konsumen dan stakeholder yang terkait melalui penggunaan metode dan pendekatan yang mampu mengintegrasikan pengembangan produk dan jasa dalam perspektif waktu yang sama.Evaluasi untuk mendukung keberhasilan implementasi PSS dapat dilakukan berdasarkan aspek sustainability, life cycle cost maupun berdasarkan perspektif konsumen dan penyedia.

Abstract

Dental Supplier Company merupakan salah satu perusahaan penyedia berbagai kebutuhan dasar kedokteran gigi yang berlokasi di Kota Padang. Ketersediaan produk menjadi faktor krusial dalam memenuhi permintaan konsumen. Berdasarkan observasi dan wawancara, ditemukan bahwa Dental Supplier Company mengalami masalah stock out dan overstock sepanjang tahun 2023 akibat belum adanya sistem pengendalian persediaan yang terstruktur. Penelitian ini bertujuan merancang sistem pengendalian persediaan untuk Dental Supplier Company, sekaligus mengembangkan aplikasi pendukung keputusan berbasis Microsoft Excel. Metodologi penelitian meliputi studi pendahuluan, identifikasi masalah, pengumpulan dan pengolahan data, serta perancangan dan validasi sistem. Teknik analisis mencakup ABC-FSN untuk mengidentifikasi dan memprioritaskan produk yang perlu dikelola secara optimal. Evaluasi kinerja persediaan untuk mengidentifikasi penyebab terjadinya produk slow moving dan non-moving. Uji normalitas untuk menentukan sebaran data permintaan mengikuti distribusi normal. Peramalan permintaan untuk memperoleh parameter permintaan yang menjadi dasar dalam perhitungan model persediaan. Model persediaan yang digunakan adalah model probabilistik Q dengan kebijakan lost sales karena sesuai dengan karakteristik konsumen, dan untuk mengatasi ketidakpastian permintaan. Penelitian ini menghasilkan sistem pengendalian persediaan hybrid yang memadukan analisis ABC-FSN dengan model Q lost sales dalam tiga lapisan. Hasil penelitian menunjukkan bahwa sistem yang dirancang berhasil mengurangi total biaya persediaan produk dental kategori AF sebesar 9,8% dan meningkatkan tingkat pelayanan, jika dirata-ratakan menjadi 99,85%.

Abstract

This research aims to develop an optimization model that systematically integrates key factors such as price, supplier capacity, Minimum order quantity (MOQ), and ordering costs into a single decision framework. The model was developed using the Capacitated Allocation Supplier Model (CASM) based on Mixed Integer Linear Programming (MILP) with a 12-period horizon (January–December 2025). The objective is to determine the optimal combination of supplier selection and order quantity allocation that minimizes total procurement costs while ensuring supply continuity. The results indicate that the CASM–MILP model successfully reduces total procurement costs from IDR 1.671.889.794,10 to IDR 1.350.088.510, yielding IDR 321.801.284,10, or 19,25% savings. Although the percentage appears modest, the savings are significant since they are achieved without disrupting production schedules or packaging availability. Moreover, the proposed model enhances transparency and rationality in decision-making and lays the foundation for future data-driven procurement systems. Overall, this research demonstrates that the MILP-based optimization approach effectively improves cost efficiency in multi-item and multi-period procurement systems, offering practical contributions for industry management and theoretical insights for operations management studies.
