Abstract

Family Farma Pharmacy is a pharmacy that provides pharmaceutical services in Bekasi Regency. There are 50 types of medicines provided in this pharmacy, but there is no medicine grouping yet. Medicine inventory control is still done manually or by monitoring medicine stocks one by one. So there is no precise and effective calculation to determine total reorders. Therefore, the aim of this research is to grouping medicines, control medicine supplies and reorder it. The methods used are Always Better Control (ABC), Economic Order Quantity (EOQ), and Reorder Point (ROP). The findings obtained were by grouping 50 types of medicines to obtain 10 types of medicines belonging to group A, 10 types of medicines in Group B, and 30 types of medicines in Group C based on the results of the ABC method. Then the EOQ results showed that the optimal order for Cataflam 50 Mg was made for 158 strips. By reordering the Cataflam 50 Mg medicine when the medicine stock reaches 15 strips in each product inventory which still has 23 strips remaining based on the ROP results.

Abstract

Efisiensi proses pencarian barang merupakan faktor krusial dalam kinerja gudang, khususnya pada aktivitas ekspor yang menuntut kecepatan dan ketepatan distribusi. PT XYZ masih mengalami permasalahan penataan barang di gudang ekspor, sehingga waktu pencarian sering melampaui standar ideal 15 menit per produk. Penelitian ini bertujuan untuk meningkatkan efisiensi operasional gudang ekspor di PT XYZ melalui penerapan metode Association Rules menggunakan algoritma Apriori. Permasalahan utama yang dihadapi perusahaan adalah penataan barang yang belum optimal, sehingga waktu pencarian barang sering melebihi standar ideal 15 menit per produk. Data transaksi ekspor selama Januari–Maret 2024 dianalisis untuk mengidentifikasi pola keterkaitan antar produk yang sering muncul secara bersamaan dalam satu transaksi. Melalui perhitungan nilai support dan confidence, ditemukan beberapa kombinasi produk dengan hubungan kuat, seperti Swatches ⇒ Dokumen dan Cranial ⇒ Wigs Human Hair, dengan nilai confidence mencapai 100%. Hasil analisis ini digunakan sebagai dasar dalam perancangan ulang tata letak gudang menggunakan perangkat lunak AutoCAD, dengan pembagian zona penyimpanan berdasarkan tingkat asosiasi produk. Evaluasi terhadap tata letak usulan menunjukkan adanya peningkatan efisiensi rata-rata waktu pencarian sebesar 25–30%, dengan waktu rata-rata menurun dari 14,95 menit menjadi 11,11 menit. Temuan ini membuktikan bahwa pendekatan berbasis data melalui algoritma Apriori dapat digunakan sebagai alat pengambilan keputusan yang efektif dalam pengelolaan gudang, khususnya untuk meningkatkan efisiensi pencarian, mempercepat proses distribusi, dan mendukung kelancaran kegiatan ekspor perusahaan.

Abstract

PT Telkom Access is a global internet service provider that plays a crucial role in developing fiber optic–based telecommunication infrastructure. One of its operational areas, located on Jl. Duri, Gambir District, Central Jakarta, faces issues related to the inefficient distribution route of the 1:4 Optical Distribution Point (ODP) serving twenty customer homes. This condition has led to 198 customer complaints in 2023 and high installation costs for the Optical Distribution Cabinet (ODC) to ODP distribution network, amounting to Rp 78,205,400. This study aims to optimize the installation cost of the Fiber to the Home (FTTH) network using a Linear Programming approach with the aid of LINGO software, as well as to design a more efficient ODC scheme on a new ODP configuration. The approach involves a comparative analysis between 1:4 and 1:8 ODP configurations, considering both technical and economic aspects of fiber optic network distribution. The results show that using an ODP 1:8 configuration with a 1:8 passive splitter in the new FTTH line produces a total installation cost of Rp 49,085,400, which is approximately Rp 29,120,000 lower than the 1:4 ODP configuration, resulting in cost optimization of 59.37%. In addition to cost savings, the ODP 1:8 configuration reduces network maintenance complexity and enhances distribution efficiency without compromising service quality. Based on these findings, this research recommends the adoption of the ODP 1:8 configuration as the optimal solution to improve cost efficiency, network maintainability, and sustainable infrastructure development in fiber optic network implementation. This strategy is expected to strengthen PT Telkom Access’s competitiveness and support sustainable global internet service performance.
