Abstract

In Indonesia, including at the Faculty of Engineering, the higher education curriculum integrates Real Work Lecture Activities (KKN). KKN aims to improve students' ability to solve community problems using science and technology. This article discusses the implementation of KKN at the Faculty of Engineering (2025),, with special emphasis on the role of students in environmental management, community welfare, and local infrastructure development. Through involvement in construction, design, and infrastructure maintenance projects, students learn to collaborate with communities, improve their technical abilities, and understand how engineering projects have a social impact. Students' social awareness and responsibility as prospective engineers are also increased through the application of problem-based learning and community service. The results of KKN at the Faculty of Engineering really help academic development and sustainable development and quality of life.

Abstract

One of the companies in East Bekasi is a company engaged in the bread industry, with the product being sandwiches. The purpose of this research is to perform raw material efficiency and cost savings of raw material inventory. In this study, identified the bread production process for 1 period (3 months). It is known that this company ordered raw materials, namely 2100 kg of flour and 480 kg of granulated sugar. However, in reality, only 1537 kg of wheat flour was used and 379 kg of granulated sugar. There is a difference between ordering raw materials and using raw materials so that the costs incurred in carrying out raw material inventory exceed the limits of the costs that have been determined by the company. The method used is the Economic Order Quantity (EOQ) method. The goal is to control the number of raw material orders made by this company and indirectly to save raw material inventory costs. The findings are comparing calculations by companies using EOQ, the efficiency of raw materials after using the EOQ method for wheat flour is 542 kg and granulated sugar is 93 kg and savings in raw material inventory costs for wheat flour is Rp. 156,437 and granulated sugar is Rp. 212,092

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.
