Abstract

This article is related to approach development in order to determine the most appropriate route for bottled water delivery from warehouse to retail from particular boundaries such as a limit on number of vehicle, vehicle capacity, and time windows to each retail. A mathematical model of VRPTW is adopted to solve the problem. Malang is one of the drinking water production centers in Indonesia, definitely it will be difficult for the company to determine the optimal delivery route with the existing restrictions. In this research hybrid genetic algorithm is use to determine the route shipping companies with the Java programming language. After analyzing the results obtained show that the results of the implementation of hybrid genetic algorithm is better than the company actual route. Moreover, authors also analyze the effect the number of iterations for the computation time, and the influence the number of iterations for the fitness value or violation. This algorithm can be applied for the routing and the result obtained is an optimal solution

Abstract

In practice, the policy of delaying payment periods is prevalent between players in a supply chain system. Generally, payments made at the end of the permitted period. Supply chain management is one of the keys to corporate sustainability that the activities have an impact on the environment.  This paper aims to develop an integrated green supply chain model with a permissible delay in payment consideration. In this research, the author develops a mathematical model to find the effect of delay in payment on emissions costs without ignoring the economic performance of a supply chain. The author develops four different scenarios model. Furthermore, numerical experiments and sensitivity analysis tests were conducted. Result of the study shows that delay in payment is integrated players into the supply chain system.  It has a positive impact on reducing supply chain emissions costs.

Abstract

In this era, companies to transfer some of their logistical functions to third party logistics (3PL). In this study, a risk evaluation, and mitigation system at the initiation of collaboration with third-party logistics companies for agricultural chemical industry companies were developed. The basic model used in system development is House of Risk combined with SOAR methodology and scenario analysis. This system is used for consideration in decision making by evaluating and giving suggestions on the extent to which the use of 3PL is used to resolve company problems due to risk. The risk evaluation and mitigation system at the initiation of cooperation with a third-party logistics company in the agrochemical industry were successfully developed. The system consists of four processes (risk identification, risk analysis, risk evaluation, and risk response) compiled based on the ISO 31000: 2009 framework

Abstract

In this article, focus on the simulation of a three-phase perishable product inventory system of a SMEs selling fresh and processed milkfish. This research was conducted to simulate a perishable product inventory system to understand and analyze the problems that occur then propose solutions to fix them. The simulation model was developed with ARENA software, simulation results of the existing condition show that there is 162 kg/month waste in fresh fish, 158 pcs/month in processed product A, and 86 pcs/month in processed product B. A model with a product renewal process mechanism was proposed to overcome this problem, and seven improvement scenarios were developed. The results obtained from the seventh improvement scenario revealed that there was a 100% reduction in fresh fish and processed product B and 94% in processed product A. Besides, there was a saving in need for fresh fish supply of 10 kg/day. In this article, we show how ARENA software can be adopted to simulate inventory system problems effectively. The method in this research can be applied to investigate various supply system scenarios and their consequences before implementing it in a real system.

Abstract

Penelitian ini dilatarbelakangi ketika peneliti melakukan observasi di Pondok Pesantren SananulHuda Blita dengan subjek santri ppengurus kandang kambing. Ketika observasi ditemukan masalah yang dihadapi oleh Mitra adalah masalah kotoran kambing. Berdasarkan diskusi dengan mitra secara luring diketahui jika masih terdapat kotoran kambing yang menumpuk dan menimbulkan bau. Hal ini juga dapat menganggu warga sekitar PP Sananulhuda.. Selain itu Mitra juga mempunyai masalah dalam pengawasan saat penyimpanan pupuk kompos . Dikarenakan jadwal pondok yang padat dan tidak selalu bisa mengawasi proses dari penyimpanan pupuk kompos tersebut. Fokus pada pengabdian ini adalah (1) memberikan pemahaman kepada santri tentang cara membuat pupuk kompos yang benar (2) Memberikan pelatihan dan pendampingan cara pembuatan pupuk kompos kepada para santri dengan menggunakan fermentor pupuk kompos berbasis IoT. Adapun hasil dari pelatihan dan pengabdian ini adalah (1) Santri dapat membuat pupuk kompos dengan baik dan benar (2) Santri dapat memnafaatkan alat fermentor pupuk kompos berbasis IoT untuk kebutuhan monitoring pupukr

Abstract

Online food delivery (OFD) businesses face several challenges, including the need for fast deliveries, a high volume of orders, and effective route planning to optimize service efficiency. This study employs the Meal Delivery Routing Problem (MDRP) algorithm to address issues related to courier assignment and capacity management in food delivery operations. The research focuses on scenarios involving a single courier, a single merchant, and multiple demand nodes. Two main methods were used in the study: (1) The Maximum Covering Model (MCM) algorithm, which identifies the coverage area of the courier, and (2) The Flexible Meal Delivery Assignment and Routing Problem (FMD-ARP) algorithm, which tackles routing challenges. Various scenarios were tested to validate the model based on the chosen routes. The aim of this research is to develop a new model and algorithm that reduces delivery time and increases the number of orders that couriers can handle. After processing and analyzing the numerical data, the study identified the most effective scenario that led to improved delivery times and benefits for couriers, enabling them to manage more orders and achieve faster delivery compared to existing algorithms.

Abstract

In a rapidly growing and competitive business era, selecting an open-source Enterprise Resource Planning (ERP) system is a critical step to support the efficiency and effectiveness of company operations. This research aims to propose an innovative methodology by integrating the fuzzy Analytical Hierarchy Process (fuzzy AHP) and fuzzy Technique for Order Preference by Similarity to the Ideal Solution (fuzzy TOPSIS) to improve the open-source ERP selection process. The method involves eight criteria and 26 sub-criteria to comprehensively evaluate 11 open-source ERP alternatives, specifically for SMEs in the transportation services sector in Indonesia. System quality has been identified as a critical factor in the selection of an open-source ERP system, with particular emphasis on aspects such as security and reliability. These sub-criteria are considered the most influential in determining the suitability of a system. The analysis further indicates that the 10th ERP alternative as the best choice, consistently outperforming others in meeting the defined criteria. Additionally, sensitivity analysis confirmed the robustness of this choice, demonstrating its stability and effectiveness despite changes in criteria weights. Beyond its practical implications for SMEs, this research contributes a versatile evaluation framework that can be adapted to other industries seeking effective ERP solutions. The findings emphasize the importance of structured decision-making in technology adoption, offering comprehensive and reliable guidance for organizations aiming to optimize their operations through open-source ERP systems. This study not only bridges a critical gap in ERP selection for SMEs but also establishes a methodological foundation for future research and applications across diverse industry sectors.
