Abstract

In general, small-scale vegetable farmers experience problems in improving the safety and quality of vegetables for supplying high-class consumers in modern retailers. Farmer Group and/or Cooperative (FGC) should be able to assist its members to meet the relevant provisions of modern retail on product specifications, delivery terms, and internal business requirements. This study proposed an agri-food supply chain (ASC) model that involves the corporate social responsibility (CSR) activities to enhance the business skills of the FGC as supplier of modern retailer. Multi-objective optimization programming is developed to determine the amount and timing of supply, level of farmers training skills, quality improvement target, and the CSR total cost. The results show that the proposed model can be used to determine the priority of programs in order to empower farmers' groups as modern retail suppliers.

Abstract

In recent years, the rising competitive environment with shorter product life cycles and high customization forces industries to increase their flexibility, speed up their response, and enhance concurrent engineering designs. To integrate these prospects, supply chain collaboration becomes a pertinent strategy for industries to strengthen their competitiveness. The network design problem is used to implement supply chain collaboration. In the buying and selling process, sharing information between buyer and supplier are important to obtain a transaction decision. The optimimum supply chain profit can be identified by mathematical model of network design problem. The Mathematical Model takes into consideration the uncertainity in negotiation of supply chain, transportation problems, and locationallocation of products from supplier to buyer in the planning based on the time value of money. The results show that the model can be used to optimize the supply chain profit. The supplier gets a profit because income were received in the initial contract, while the buyer profit comes from lower pay.

Abstract

Indonesia's economic sector continues to rely on carbon-emitting fossil fuels. The government is speeding up electrification by encouraging people to switch from traditional to electric automobiles. Electric motorcycles are one option for lowering CO2 emissions. Many researchers have investigated the value attributes affecting consumers’ attitudes and behavior around electric motorcycles. The structural model was created using the Partial Least Square ”“ Structural Equation Model (PLS-SEM). The questionnaires were circulated through the internet, and 1,223 valid responses were received. Researching people's interest in environmentally friendly vehicles and the growing ecosystem of electric vehicles will indicate that the electric motorcycle business has a bright future. This research also shows that attitude is a major impact on electric motorcycle purchase intention and infrastructure, and subjective norms and perceived behavioral control have a direct effect on electric motorcycle purchase intention. Cost and technology do not influence a person in determining his desire to buy an electric vehicle.

Abstract

Most of the technology from universities (PT) related to technological innovation often fails to enter the market. This problem then becomes the basis and object of improvement in technology-based entrepreneurial practices (technopreneurs). Learning is carried out through Independence Learning Campus Independence (MBKM) which converts courses according to training subjects in collaboration with PUI UNS and BPPT. This practice is a model of participatory and collaborative learning, in which students are directly involved in solving existing case studies and act as perpetrators of technology commercialization and become technopreneurs. Students are initially given training materials in accordance with the curriculum and direct learning from existing tenants. As a result, through this learning process, students can design business process proposals that exist in tenants. The success of this learning method was assessed based on technopreneur analysis from students in answering problems faced by tenants based on aspects of product technology innovation, product development, business development, and its implementation at BMC. One of the tenants who is the object of the case study in this study is the start-up PT. EKM who have problems with the commercialization of technology in the case of konverter kit products.

Abstract

The adoption of electric vehicles (EVs) is one of the solutions to reduce emission problems. Vehicle cost analysis is one of the keys to seizing the Indonesian market. As a consumer, it is not only the purchase price that needs to be considered, but the life cycle costs throughout ownership also need to be considered in the purchase. This study discusses the life cycle cost (LCC) of EVs in Indonesia, especially electric motorcycles (EMs), which will be compared with conventional motorcycles (CMs). In particular, this study aims to encourage the government's target for ownership of 2.1 million EMs in Indonesia by 2025. The novelty of this research is to develop a more comprehensive LCC model by considering the costs in terms of tangible and intangible to compare the two types of motorcycles using Monte Carlo simulation. This simulation is used to coordinate the behavioral uncertainty of motorcycle users. As a result, the value of an EM is more economical than CM for various users. The average value percentage of EMs is lower than CMs by 45% (IDR 30,6 million). In addition, several scenarios are also analyzed to maximize consumer welfare in Indonesia.

Abstract

The users of electric motorcycle in Indonesia are currently still limited. This is due to three main things, namely the limited amount of energy charging infrastructure, the lack of socialization regarding the knowledge of technical aspects of electric motorcycle and the financing aspects of electric motorcycle ownership. This research develops a conceptual design business model canvas of Mobile Battery Swap Charging Stations (MBSCS) for electric motorcycles which aim to find solutions to the three problems above. The development of the MBSCS model is an alternative to increase the number of electric charging infrastructure quickly, because the advantages of MBSCS include having a higher level of flexibility and simpler installation than Fixed Charging Stations. This research combines the need of increasing infrastructure and improving socialization to the community regarding the advantages of using electric motorcycle through marketing communication media. Increasing the understanding of technical aspects of electric motorcycle is expected to increase people's motivation to adopt electric motorcycle. This research uses secondary data to explore MBSCS business canvas model (BMC), MBSCS ecosystem, and MBSCS prototype design. The analysis illustrates the MBSCS ecosystem that align with the motorcycle users in Indonesia.  The existence of MBSCS is expected to significantly increase the buying interest, adoption, and diffusion of electric motors more broadly.
