Abstract

The supply chain sector is one of the most determining the company's ability to maintain its business operations. PT. Sentra Mulia Sejahtera has never conducted performance measurements on its supply chain flow, so it is not yet known how efficient its supply chain performance is. The purpose of this study is to analyze the level of efficiency of supply chain performance and propose improvement strategies for the inefficient supply chain performance of PT. Sentra Mulia Sejahtera using the Data Envelopment Analysis method. The results showed that at the supplier level there was 1 DMU that was already efficient, 2 DMUs were marginally efficient and 2 other DMUs were still inefficient. Meanwhile, at the company level, there are 4 DMUs in an inefficient condition, DMU 3 is the DMU with the lowest efficiency value of 38.5%. The improvement strategy for inefficient suppliers is to reduce the value of the input variables. The improvement solution for the company based on the results of the potential improvement calculation must reduce the cash to cash cycle time and lead time for order fulfillment by reducing the length of the payment agreement from the distributor.

Abstract

Penelitian ini mengkaji bagaimana manajemen rantai pasok diterapkan pada industri rumahan tahu di Kelurahan Moodu, Kota Gorontalo. Permasalahan utama yang dihadapi pelaku usaha adalah ketergantungan pada satu pemasok bahan baku dan permintaan pasar yang tidak menentu. Tujuan dari penelitian ini adalah untuk memahami bagaimana usaha ini mengelola aliran produk, informasi, dan keuangan agar kegiatan operasional tetap berjalan lancar. Pendekatan yang digunakan adalah deskriptif kualitatif melalui observasi langsung, wawancara dengan pemilik usaha, dan studi dokumentasi. Hasil penelitian menunjukkan bahwa meskipun dilakukan secara sederhana, manajemen rantai pasok di UMKM ini berjalan cukup efektif, Rangkaian aktivitas dalam manajemen rantai pasok dimulai dari tahap perolehan bahan baku, dilanjutkan dengan kegiatan produksi, hingga tahap akhir berupa penyaluran produk ke tangan konsumen melalui sistem distribusi yang terorganisir, hingga pemanfaatan limbah produksi menjadi pakan ternak. Keberhasilan usaha ini tidak lepas dari hubungan kepercayaan yang terjalin dengan mitra usaha, sistem pembayaran yang fleksibel, serta kemampuan adaptif dalam menghadapi perubahan permintaan. Temuan ini menunjukkan bahwa pengelolaan rantai pasok yang baik tidak selalu membutuhkan teknologi canggih, melainkan bisa dijalankan secara fungsional dengan pendekatan yang sesuai dengan kondisi lokal dan sumber daya yang tersedia.
