Abstract

Production control of cashew nuts greatly affects the profits earned by the company. When cashew nut raw materials exceed production needs, it results in storing cashews for an extended period, causing the cashew products to lose freshness, and the quality of processed cashews deteriorates. If the raw materials are damaged, the manufacturer must acquire additional costs to procure raw materials again. Another issue is that cashew nut raw materials are seasonal products and are not always available.To solve these problems, a calculation method is needed to control optimal production inventory to minimize the company's expenditures. The method used is to formulate the problem into a Fuzzy Linear Programming mathematical model using a combination of methods: the Simplex algorithm and Duality Theory. The case implementation focuses on the uncertainty of cashew nut production quantities outside the harvest season. Moreover, the calculation of an optimal production quantity to minimize resulting losses is needed. The output generated is an optimal production prediction using the combination of the Simplex Algorithm and Duality Theory in solving Fuzzy Linear Programming.

Abstract

Advances in digital technology have changed the way people carry out their daily activities, including ordering and enjoying food. This trend opens up great opportunities for local business actors to adapt through application-based service innovation. Deliboy Delivery Boyolali is a local startup developed to make it easier for people to order food online, as well as support the transformation of delivery services in the Boyolali area. So far, Deliboy's ordering system still depends on the website platform connected to WhatsApp. Although practical, this method often causes obstacles such as improper data recording, time-consuming manual processes, and limitations in determining delivery prices according to distance. Based on this problem, this research offers a solution through the development of an android-based mobile application that integrates three main roles, namely admin, customer, and driver. System development is carried out using the Software Development Life Cycle (SDLC) method through the stages of needs analysis, design, implementation, and testing. The application is developed with the Flutter framework for the user interface, Laravel as the backend server, and MySQL as the database. The testing process applies the Black Box Testing method to ensure the suitability of the functions with the system specifications. The test results showed that all key features, including food ordering, location tracking, digital payments, and a distance-based dynamic pricing system, were working optimally. The implementation of this system has been proven to improve the accuracy of cost calculations, and make it easier for drivers to determine delivery rates automatically based on distance, thus creating a more transparent, effective, and easy-to-use system.

Abstract

Inventory management in retail stores often faces constraints regarding recording accuracy, restocking delays, and difficulties in preparing reports when processes are still carried out manually. This research designs and implements a mobile-based inventory application in a Retail Store case study to handle login–register authentication, mapping of item storage locations, management of categories and item data, recording of in-out transactions (not POS/cashier), sales visualization based on item outflow in bar diagrams, and periodic reports of incoming and outgoing goods. The development methodology applied is Black-box Functional Testing on core scenarios. Black-box functional testing on 9 core scenarios achieved a 100% success rate, covering login–registration, master data management, incoming–outgoing transactions, stock-outflow visualization, and report export. The system architecture adopts Flutter on the client side, Node.js–Express on the service side, and MySQL on the database side. The development methodology is iterative, covering requirements elicitation, data model design with ERD and process flow with DFD, module implementation, and black-box functional testing on core scenarios. The implementation results demonstrate that all modules operate according to specifications: transactions automatically update stock, visualization highlights best-selling products through stock outflow indicators, and period reports support restocking decisions. These findings affirm that the application successfully enhances operational efficiency and employee productivity due to faster and easier recording, mitigates the risk of item data loss, and provides accurate analysis regarding stock outflow that aids in predicting and optimizing restocking policies.

Abstract

Transformasi digital memberikan peluang besar bagi sektor usaha ritel, khususnya pada Usaha Mikro, Kecil, dan Menengah (UMKM), dalam meningkatkan efisiensi operasional dan daya saing. Namun, banyak toko ritel tradisional masih menghadapi kendala dalam pengelolaan persediaan akibat penggunaan sistem manual yang rentan terhadap kesalahan pencatatan dan keterlambatan pembaruan stok. Penelitian ini bertujuan merancang dan mengimplementasikan aplikasi mobile berbasis Android untuk pengelolaan persediaan ritel UMKM yang bersifat multi-toko, selama produk yang dikelola memiliki identitas barcode. Metodologi penelitian menggunakan analisis persediaan FSN (Fast-Slow-Non-Moving) dan TOR (Turn Over Ratio), pemodelan sistem menggunakan DFD dan ERD, serta pengujian fungsional dengan Black-Box Testing. Pengujian sistem dilakukan menggunakan skenario data transaksi ritel UMKM yang tersimpan pada sistem untuk memvalidasi proses klasifikasi persediaan. Kontribusi penelitian ini terletak pada otomatisasi klasifikasi FSN berbasis backend secara real-time pada lingkungan multi-toko UMKM, yang sebelumnya umumnya dilakukan secara manual. Hasil penelitian menunjukkan bahwa proses klasifikasi FSN yang sebelumnya membutuhkan waktu sekitar 10–15 menit untuk satu set data dapat dipangkas menjadi kurang dari 1 detik, sehingga meningkatkan efisiensi waktu pemrosesan dan mendukung pengambilan keputusan pengendalian persediaan secara lebih cepat dan akurat.
