Abstract

Pertumbuhan jumlah pengguna kendaraan bermotor di Indonesia yang semakin pesat mendorong munculnya banyak produsen otomotif. Salah satu produsen otomotif di Indonesia adalah PT X. Dalam mempertahankan daya saingnya, PT X berupaya untuk meminimasi biaya. Sebagai perusahaan otomotif yang dipasok banyak pemasok maka sistem pengiriman komponen menjadi sangat penting. Adanya kondisi fluktuasi biaya bahan bakar, maka biaya logistik pengiriman komponen berpotensi untuk diminimasi. Dalam meminimasi biaya logistik tersebut selama ini PT X menerapkan sistem pengangkutan milkrun untuk mengirim komponen. Efektifitas dan efisiensi rencana pengiriman dengan sistem ini selain diukur dari aspek biaya juga diukur dari aspek utilitas volume truk. Pencapaian utlitas truk untuk pabrik B PT X selama enam bulan pengamatan belum mencapai target. Sehingga akan dilakukan perencanaan rute dengan beberapa alternatif untuk meningkatkan utilitas truk dan mengurangi biaya pengiriman. Dalam proses penyelesaian masalah ini, dikembangkan empat skenario rencana pengiriman yaitu skenario 1 (rute dari klaster lama PT X), skenario 2 (rute dari klaster perbaikan), skenario 3 (rute dari klaster baru) dan skenario 4 (rute dari perbaikan rute lama). Klaster perbaikan diperoleh dengan menggunakan metode klasifikasi K-Nearest Neighbor (KNN) sedangkan klaster baru menggunakan teknik klaster Divisive. Penentuan rute pada tiga skenario pertama menggunakan penggabungan Saving Method heuristic dan Nearest Neighbor serta langkah modifikasi tambahan. Sedangkan pada skenario terahir hanya digunakan langkah modifikasi tambahan karena sudah terbentuk rute. Pemilihan skenario rencana pengiriman dinilai dari aspek utilitas truk dan biayanya. Pendekatan perhitungan dan analisa yang dilakukan menghasilkan bahwa empat alternatif pengiriman lebih baik dari rute pengiriman lama dan rencana pengiriman terbaik adalah skenario 2 (rute kelompok perbaikan) dan penghematan sebesar 22.6% dengan utilitas truk sebesar 90%. Klaster pemasok yang terbentuk berpengaruh besar terhadap rute dan pencapaiannya. ========== Growth in number of automotive user in Indonesia that more rapidly encourage the emergence of many automotive manufacturers. One of automotive manufacturers is PT X. in maintaining its competitiveness, PT X makes serious efforts to minimize cost. As automotive company that supplied by many suppliers, the delivery system of part becomes very important. The condition of the rising cost of fuel, parts delivery logistic cost has the potential to be minimized. In minimizing logistic cost, during this PT X apply milkrun transport system to pick up parts. Beside measured from the cost, effectiveness and efficiency of the delivery planning with this system also measured from truck volume utility. Truck utility achievement for plant B PT X during six month of reservation has not reached the target. So it will be route planning with some alternatives for increasing truck utility and delivery cost minimizing. In this problem solving process, generated four scenario of delivery planning, they are scenario 1 (route from old cluster PT X), scenario 2 (route from improved cluster), scenario 3 (route from new cluster) and scenario 4 (route from improved old route). Improved cluster is obtained using K-Nearest Neighbor (KNN) classification method, while new cluster is obtained using Divisive hierarchy cluster technique. Route planning on first three scenario is obtained using combination of Saving Method heuristic and Nearest Neighbor and additional modification step. On the last scenario, route is obtained just using additional modification step because route is already built. Selection of scenario of delivery planning is assessed on the aspects of truck utility and the cost Calculation approach and analysis get the result that four delivery alternatives are better than existing delivery route and the best delivery planning is scenario 2 (route from improve cluster/group) with 22.6% saving and 90% truck utility. Supplier cluster that formed has big impact on route and its achievement
