Abstract

This study aims to analyze the effect of promotional strategies on consumer purchasing decisions for Freedom Street Wear products on the Shopee platform. The research population consists of Shopee users who have purchased products from official stores. A quantitative approach using a survey method was applied, and data was collected from 100 respondents selected through non-probability sampling. Multiple linear regression analysis was used to test the influence of each variable, both partially and simultaneously. The findings show that Double Date Discount has a positive and significant effect on purchasing decisions. Meanwhile, Free Shipping and Cash on Delivery (COD) did not have a significant effect, although COD showed a positive trend. Simultaneously, these three variables were found to have a significant effect on consumer purchasing decisions. In addition to examining the individual effects of promotional strategies, this study also explored the interactive relationships between the variables. It was found that while Free Shipping and COD did not individually influence purchasing decisions, their combination with other promotional strategies like Double Date Discount enhanced the overall effectiveness of the promotions. This suggests that promotional strategies should be strategically integrated to maximize their impact on consumer behavior. Furthermore, the study highlights the growing importance of e-commerce platforms like Shopee in influencing purchasing decisions and shaping consumer perceptions. As online shopping continues to grow, understanding the nuances of promotional strategies is essential for businesses aiming to attract and retain customers in a competitive market. The findings contribute to a deeper understanding of the factors driving consumer purchasing decisions and offer valuable insights for businesses looking to optimize their promotional efforts in the online retail environment.

Abstract

Efficient distribution is a critical factor in the food sales industry to ensure product quality, cost effectiveness, and customer satisfaction. The reliance on third-party online delivery services for distributing raw food ingredients has created significant logistics costs for a healthy food company in Bandung. To address this issue, the company aims to manage its own logistics using available delivery vehicles. The main challenge lies in determining the optimal delivery route that minimizes time and cost while serving an increasing number of outlets. This study applies a constructive heuristic approach to the Vehicle Routing Problem (VRP), since no prior research has examined delivery routes for this company. Constructive heuristics are chosen for their ability to provide feasible solutions that are easy and quick to implement. Two methods are employed: the Nearest Neighbor and the Nearest Insertion. The results indicate that the Nearest Neighbor method produces a total distance of 70.3 km, while the Nearest Insertion yields 68.1 km. Thus, the Nearest Insertion method achieves a shorter route by 2.2 km, equivalent to a 3.1% reduction compared with Nearest Neighbor. Based on these findings, the Nearest Insertion method is selected as the optimal route. This research provides a practical initial framework for improving logistics efficiency in food distribution and can serve as a foundation for future optimization studies.

Abstract

The demand for products that require high precision is increasing. Therefore the production process with CNC machines is highly crucial. In the milling machining process, the roughing process takes the most time. The suitable selection of tools combination for the machining area will reduce the machining time. Roughing process sometimes cannot process the machining area with the minimum gap size. The research is to develop tools combination selection algorithm with the criteria of reducing machining time by considering the minimum gap in the workpiece machining area. The first stage is the preprocessing stage, which aims to initiate the tool size that can be used in the workpiece machining process and tools size grouping for the smallest gap machining process. The second stage is genetic algorithm (GA) stage, which aims to find the best tools combination according to the objective function. The sequence in the GA stage is determining initial solution, parents selection, crossover, mutation, regeneration, and determining the best solution. The developed algorithm has been tested on four workpieces. Characteristics of the features were tested on two closed pocket workpieces with island, each open pocket with island, and close pocket without island. Development of tools combination selection algorithm can assist in determining the best tools size to minimize the machining time.

Abstract

High distribution costs pose a significant challenge for Small and Medium Enterprises (SMEs), such as Dietgo Kitchen in Bandung, which inefficiently relies on third-party online delivery services to distribute ingredients to its seven branches. This point-to-point logistics issue increases total operational costs and erodes profit margins. To address this, an intervention in the form of Vehicle Routing Problem (VRP) Implementation Training and Mentoring was conducted for the company's distribution team, aimed at utilizing the company's unoptimized food trucks for autonomous delivery. The training focused on mastering the VRP heuristic methods, namely Nearest Neighbor and Nearest Insertion, to determine optimal delivery routes from the central warehouse to all outlets. This mentoring included actual field data acquisition, route simulations, and structured delivery management training. Evaluation results showed a significant positive impact, with a 43.71% reduction in delivery costs compared to the average of the previous three months. While employee adaptation to the new VRP system and methods is still required, this implementation demonstrates that VRP is an effective strategic instrument for achieving delivery route efficiency and reducing routine operational costs for SMEs.

Abstract

The development of digital technology has encouraged MSMEs to start adopting online sales systems to improve the efficiency of transaction management. However, some MSMEs still carry out business processes manually without the support of an intergrated system. This study aims to design and test an e-commerce website prototype as an initial model for digitization in animal feed MSMEs. This study uses a software engineering approach with the Waterfall method System Development Life Cycle (SDLC) model, which includes the stages of requirements analysis, design, implementation, and testing. The system was developed using PHP and MySQL and run on a localhost environment. Testing was conducted using the Black Box Testing method to verify the suitability of the system functions with the requirements specifications. The results of the study show that all the main features, such as product management, shopping cart, checkout process, and transaction recording, work according to the design. This study produced a functionally feasible system design as the initial stage of e-commerce system implementation in animal feed MSMEs. Further testing in an online environment and user evaluation are needed to assess the effectiveness of the system empirically.   Keywords: e-commerce, MSMEs, digitalization, website

Abstract

Penelitian ini bertujuan untuk mengoptimalkan rute pengiriman bahan makanan ke berbagai gerai PT X di Kota Bandung guna mengatasi masalah efisiensi biaya dan jarak tempuh. Sebelumnya, perusahaan mengandalkan layanan pihak ketiga dan metode heuristik konvensional seperti Nearest Insertion yang memiliki risiko terjebak dalam solusi optimum lokal. Sebagai solusi strategis, penelitian ini menerapkan metode metaheuristik Tabu Search untuk memperbaiki rute distribusi dalam kerangka Vehicle Routing Problem (VRP). Metode Tabu Search dipilih karena kemampuannya dalam mengeksplorasi ruang pencarian secara luas melalui mekanisme tabu list, yang secara efektif mencegah pengulangan langkah dan membantu algoritma keluar dari jebakan solusi lokal untuk mencapai hasil yang mendekati optimum global. Data penelitian berupa jarak antar depot dan delapan outlet diolah menggunakan perangkat lunak Matlab 2021 dengan parameter 100 iterasi. Hasil simulasi menunjukkan bahwa metode Tabu Search mampu menghasilkan rute yang lebih efisien dibandingkan metode sebelumnya. Total jarak distribusi berhasil dipangkas dari 68,1 Km (hasil metode Nearest Insertion) menjadi 64,3 Km. Pengurangan jarak ini membuktikan bahwa pendekatan sistematis melalui algoritma metaheuristik dapat memberikan penghematan operasional yang signifikan bagi perusahaan. Penelitian selanjutnya disarankan untuk mengintegrasikan variabel tambahan seperti kapasitas kendaraan dan jendela waktu pengiriman (time windows) guna memperoleh model distribusi yang lebih komprehensif.
