Abstract

UMKM Gerai kimia merupakan industri kimia berskala mikro yang memproduksi sabun pembersih. Pengiriman produk harus sesuai dengan permintaan pelanggan dan dilakukan secara optimal, sehingga proses distribusi tidak mengakibatkan pemborosan biaya, jarak dan waktu. Pendistribusian produk yang dilakukan UMKM Gerai Kimia masih belum efektif dan acak, tidak memperhatikan lokasi, jarak retail yang dituju dan beban angkut yang mengakibatkan besarnya biaya yang dikeluarkan perusahaan. Penelitian ini bertujuan untuk meminimalkan biaya distribusi dengan cara mengoptimalkan rute distribusi dengan memperhatikan lokasi konsumen, jumlah permintaan konsumen, jarak gudang ke konsumen, dan beban angkut kendaraan. Pengoptimalan rute distribusi dilakukan dengan menggunakan metode saving matrix sehingga dapat memperpendek jarak tempuh dan menghemat biaya distribusi. Berdasarkan hasil penelitian dengan menggunakan metode saving matrix, jarak tempuh per bulannya dapat dihemat sebesar 14% - 24%, dan biaya distribusi selama satu tahun yang awalnya sebesar Rp 7.740.000 menjadi Rp 6.267.998,3 yang artinya terjadi penghematan sebanyak Rp 1.472.001,7 dan efisiensi biaya sebesar 19,01% selama satu tahun.

Abstract

ABSTRACT The queue process at UMKM El Laundry is a process related to the arrival of consumers who bring dirty clothes and then wait in line, then the dirty clothes are finished processing and the consumers leave the laundry. The current conditions at UMKM El Laundry are with an average number of arrivals of 20 people/day with the number of dirty clothes 20 kg/person. This has resulted in a buildup in serving consumers, where currently the service time limit applied by UMKM themselves is 8 hours/day for regular services. Data was obtained through observation for 1 month, namely in December 2022. The queuing method used is Multi-channel - single phase using Anylogic simulation. The results of calculations using the Multi-channel - single phase method show that queues occur due to lack of facilities in the process. After being analyzed using Anylogic simulation, it was proven that the queue could be minimized by adding washing machines, which were originally 3 units, to 4 units, and dryer machines, which were originally 3 units, to 4 units. So that the Queue Length which was originally 0.04 minutes became 0.94 minutes, Queue Time per agent from previously 0.50 minutes to 6.14 minutes, and service utilization which was originally 0.18 minutes to 0.75 minutes or 75% more fast in the service process, so that queues can be minimized.

Abstract

The success of children in learning is strongly influenced by several factors such as the teacher, tools or facilities, facilities and infrastructure, the surrounding environment. One of the educational facilities and infrastructure that supports learning that is not given enough attention is the study desks and chairs for students in class. Tables and chairs are one of the most closely related factors in improving the quality of learning. If the tables and chairs are not ergonomic, during the learning process students will easily feel tired and not focus when learning takes place.This study aims to determine the factors that influence musculoskeletal complaints in students and find out whether adjustable tables and chairs can reduce these complaints. Completion in this study using anthropometric methods.The conclusion of this study is that there are several factors that cause musculoskeletal disorders, namely non-ergonomic seating, high chairs, high tables, inappropriate sitting positions, and sitting too bent. Where the results of the study stated that each table and chair size must be in accordance with its users, so that it can be used comfortably.   Keywords: adjustable tables and chairs, musculoskeletal, anthropometry.

Abstract

PT. LogistikEkspresindoUtama is a service company that has integration services ranging from land, sea and air Freight Forwarding services, PPJK (Customs Service Management Company), and Transportation Management for Projects, which is supported by a complete selection of land, sea and air transportation fleets specializing in handling cargo that requires special handling both at home and abroad. The company's subjective judgment alone has been used to choose the current route, and the shipping cost has not been considered. As a result, a unique approach is required to solve this issue. Consequently, this research aims to identify a cost-effective route and optimize distribution costs. This study uses the Integer Linear Programming method to optimize the delivery of goods and minimize transportation costs. Based on the data processing results using the Integer Linear Programming method, it can minimize the distance of 604 km or 13.04%; the minimum travel time is 14.9 hours or 12.88%; the minimum total distribution cost is Rp 1,154,650 or 16.47%. PT. Logistik Ekspresindo Utama merupakan salah satu Perusahaan Jasa yang memiliki layanan integrasi mulai dari jasa Freight Forwardingdarat, laut maupun udara, PPJK (Perusahaan Pengurusan Jasa Kepabeanan), Manajemen Transportasi untuk Project, yang didukung oleh pilihan lengkap armada transportasi darat, laut dan udara spesialisasi dalam menangani kargo yang membutuhkan penanganan khusus baik di dalam maupun luar negeri. Penilaian subjektif perusahaan saja yang digunakan untuk memilih rute saat ini, dan biaya pengiriman belum diperhitungkan. Akibatnya, untuk menyelesaikan masalah ini, diperlukan pendekatan yang unik. Oleh karena itu, tujuan penelitian ini adalah untuk mengidentifikasi rute yang hemat biaya dan mengoptimalkan biaya distribusi. Penelitian ini menggunakan metode Integer Linear Programming untuk mengoptimalkan pengiriman barang dan meminimalkan biaya transportasi. Berdasarkan hasil pengolahan data menggunakan metode Integer Linear Programming dapat meminimumkan jarak tempuh sebesar 604 km atau 13,04%, minimum waktu tempuh sebesar 14,9 jam atau 12,88%, minimum total biaya distribusi sebesar Rp. 1.154.650 atau 16,47%.

Abstract

The rapid development of industry and increasingly fierce competition between companies encourage companies to maintain their existence by planning and developing competitive strategies. Increasing efficiency is the key to achieving greater benefits, such as increasing the effectiveness of assets in product development and achieving production targets. Measuring productivity is an important indicator in managing company resources. The Sumedang ABC Tofu Factory, as a home industry, experienced a decline in productivity due to suboptimal use of resources, such as labor, raw materials, energy and capital. The American Productivity Center (APC) method is used to measure productivity and identify factors causing decreased productivity. The measurement results show a decrease in productivity in periods 2 and 3 compared to the base period. Based on the analysis of the productivity index, profitability index, and price improvement index, the improvements needed include saving and monitoring the use of raw materials and energy, as well as reducing less than optimal capital. Companies can implement improvement solutions to increase production productivity and strengthen competitiveness in the market
