This happens because of each vehicle can only deliver to one distribution center at a time. This makes the load factor level of vehicle utilization below 20%. This study aims to obtain the optimal route and delivery schedule to improve distribution efficiency and increase the load factor of vehicle capacity utilization. This quantitative research method uses the Saving Matrix algorithm on all distribution channels. The results obtained indicate that the optimal delivery routes are 5 to 6 cluster. This saves mileage of up to 144 km per route per day and saves distribution costs of up to Rp. 39,146.50 for one delivery. In addition, there was an increase in the load factor of 18.37% for dropping 1 and 16.49% for dropping 2. By using the proposed route, a resume of the delivery schedule is obtained with clearer departure and arrival times and saving times up to 275 minutes. Furthermore, the expansion of the scope of research and comparing the level of effectiveness between distribution centers in various regions can be carried out as a follow-up study.

Hal ini terjadi karena setiap kendaraan hanya dapat mengirim ke satu pusat distribusi dalam sekali jalan. Hal ini membuat tingkat load factor utilisasi kendaraan di bawah 20%. Penelitian ini bertujuan untuk mendapatkan rute dan jadwal pengiriman optimal untuk meningkatkan efisiensi distribusi dan meningkatkan load factor utilisasi kapasitas kendaraan. Metode penelitian kuantitatif ini menggunakan algoritma Saving Matrix pada semua jalur distribusi. Hasil yang diperoleh menunjukkan bahwa rute pengiriman yang optimal adalah 5 hingga 6 cluster. Hal ini menghemat jarak tempuh hingga 144 km per rute per hari, dan menghemat biaya distribusi hingga Rp. 39.146,50 untuk satu kali pengiriman. Selain itu terjadi peningkatan pada load factor sebesar 18,37% untuk droping 1 dan sebesar 16,49% untuk dropping 2. Dengan menggunakan rute yang diusulkan, resume jadwal pengiriman diperoleh dengan waktu keberangkatan dan kedatangan yang lebih jelas dan memberikan penghematan waktu perjalanan hingga 275 menit. Selanjutnya, Perluasan ruang lingkup penelitian dan membandingkan tingkat efektivitas antar pusat distribusi di berbagai daerah dapat dilakukan sebagai penelitian lanjutan. Kata kunci— Algoritma Saving Matrix; Rute pengiriman; Load Factor; Penjadwalan I. INTRODUCTION PT Pos Indonesia (Persero) is a State-Owned Enterprise (BUMN), which is engaged in shipping services and financial services since August 26, 1746. The services are provided by PT Pos Indonesia (Persero) focuses on the activities of sending packages and documents/letters. However, along with the development of online buying and selling, this has led to high demand for package delivery in the community for delivery services and has become one of the triggers for increasingly strong competition between shipping service companies.
