Abstract

This paper discusses the implementation of five key strategies of reducing dwelling time at ports. The five strategies are deregulation of administrative procedures, availability of infrastructure and port facilities, integration of information technology, quality of services, price and incentive strategies. By using partial least squares method and bootstrapping testing, these five variables are a good fit, reliable, and robust as a factor for reducing dwelling time at the port. However, the implementation at Ports in Indonesia still needs to be improved. Four strategies have been running well and they have a significant effect either directly or indirectly on the decrease of dwelling time, namely deregulation of administrative procedures, availability of infrastructure and port facilities, integration of information technology, dan quality of services. While price and incentive have not been maximized to reduce dwelling time at Ports in Indonesia.

Abstract

The Muhammadiyah University of Surakarta team seeks to develop an urban-concept car to participate in the KMHE 2019. The KMHE (Energy Efficient Car Contest) is a competition for students to create safe, economical and environmentally friendly vehicles held by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia. One of the most critical components of a car is the body. The body should be able to protect the driver, and its specifications affect the vehicle's performance. Thus, this research is performed to obtain a sound body design. In designing the body, a three-dimensional visual design modeling using Solidworks 2016 is performed. The specifications of the body are following the KMHE regulations. Afterwards, mass calculation and flow simulation are performed to evaluate the performance of the design. The results are the total body mass is 38.35 kg, and the airflow on the body surface is dominated by laminar flow.

Abstract

Businesses always compete to improve customer satisfaction. A firm engaged in as a distributor as well, always try to provide satisfaction to their customer, in this case, retailer and wholesales. The distributor can improve retailer satisfaction by providing such information that suits retailer requirements in the pursuit that the supply chain flow can move quickly, particularly on the flow of products from the manufacturing ordered by the distributors. This study aims to obtain a relationship between distributors and retailer companies. This study surveyed 100 retailers, and wholesale companies engaged in Fast Moving Consumer Goods (FMCG) and the supplier domiciled in the city of Makassar, South Sulawesi, with revenues of more than IDR 300,000,000. - / year. SmartPLS software version 2.0 was used to test the hypothesis. The results of the study found that information quality can provide a positive increase in improving supplier relationship management. Adequate information quality cannot significantly increase supply chain flexibility and retailer satisfaction. Supplier relationship management built by distributors can have an impact of 0.611 on supply chain flexibility in retail and retail satisfaction companies of 0.367. The stronger distributor and retailer relationship can increase distributor flexibility and retail satisfaction. Supply chain flexibility built by distributor companies can have a significant impact on retailer satisfaction of 0.463. This research provides an improvement in the development of supply chain management theory, in particular, building relationships with customers.

Abstract

Volatile and vulnerable conditions during disaster relief cause many problems on the coordination of aid replenishments. Research states that partnership improves coordination thus reducing the uncertainty condition along supply chain including in replenishment. This paper aims to fulfill the research gap on examining the impact of partnership in the disaster relief process. Dynamic characteristics model of this case was built by modifying the beer distribution game through Vensim PLE Plus. Model had been validated and verified with the West Java Regional Disaster Management Authority (BPPD). The simulation was run for for two types of product: repetitive demand (food package) and one-time demand (blanket). Total cost, bullwhip effect, and total distribution time for each scenario are then compared. The simulation results show that the proposed scenario, which is developed based on the usage of blockchain on the partnership system, can reduce the total distribution time for about 43% for blanket and 27% for food package. Meanwhile, the total cost for blankets can be reduced for about 29% and 13% for food packages. But on the other side, the partnership system had aggravated the bullwhip effect. Some future potential researches are also proposed in this study.

Abstract

This paper investigates whether indicators on the ease of doing business explain variation of financial system vulnerability amongst eight biggest European economics between 1999 and 2014. Using mixed-effects estimation method for sectoral observations nested within countries, the results suggest that easy access to get credit is associated with increased financial vulnerability, as measured by decreased excess return in equity market. The significance of political stability, regulatory quality, and rule of law also marks the role of institutional environment towards vulnerability by facilitating the openness towards new business. Finally, a high degree of openness is not always good especially if they are combined with better institutional environment. This confirms the importance of the level of openness, as well as its channels, in determining the extent of vulnerability.

Abstract

The double row layout problem (DRLP) is an NP-hard and has many applications in the industry. The problem concerns on arranging the position of  machines on the two rows so that the material handling cost is minimized. Although several mathematical programming models and local heuristics have been previously proposed, there is still a requirement to develop an approach that can solve the problem efficiently. Here, a genetic algorithm is proposed, which is aimed to solve the DRLP in a reasonable and applicable time. The performances of the proposed method, both its obtained objective values and computational time, are evaluated by comparing it with the existing mathematical programming model. The results demonstrate that the proposed GA can find relatively high-quality solutions in much shorter time than the mathematical programming model, especially in the problem with large number of machines.

Abstract

Many traditional methods in evacuation route planning are motivated by the operational objective, such as total travel/clearance time. Little attention has been given to the human factor and the safety aspect of the evacuees during the planning phase. Our study aims to propose a simple yet practical route planning method that simultaneously considers human behavior, safety factor, and the travel time in a volcanic crisis context. The planning model is developed based on the shortest-path problem with a joint-cost parameter representing the three aspects. We present a large-scale street network in Merapi volcano as a case study. The result implies that employing a joint-cost parameter is effective for creating an evacuation route that is reasonably safe and in line with human cognition in navigation. The finding offers practical insights for the stakeholders as part of the greater effort to develop a systematic disaster management plan.

Abstract

During the Covid19 pandemic, many local business were struggling to survive. With the rising of click and collect solutions, business strives to survive by offering pick-up points and maintaining the social distance policy. The demand for goods and services of customers are met instantly from the local offline shops via digital platform. Meanwhile, local businesses in a specific geographical area are still striving from the hard times due to least popularity and competitivenes in the services such as delivery. Hyperlocal delivery comes into the logistics industry to meet the issues from local businesses. While the hyperlocal delivery terminology is still new, there have been some real world practices. This study attempts to define the hyperlocal delivery and explore multiple case studies to analyze the on-foot delivery as a rising of quick commerce in the gig economy. The multiple case studies will take place on the hyperlocal delivery business models in South Korea. The overview of the hyperlocal “on-foot” delivery will be described in four dimension of analysis; strategy, customer, cost-revenue, and process model. At the end, some research challenges and opportunities are presented to show how the research communities can contribute to the field
