Abstract

Value added is an indicator of the economic strength of a business. There are several ways to increase added value, namely by processing into new products, preserving, making attractive packaging, and improving the quality of a product. Most of the yield of purple cassava in the Karangnyar area is still sold in the form of raw products and has not been much processed, so the added value is still low. This study identified various processed cassava products, analyzed the added value of processed products, analyzed the added value of purple cassava supply chain and proposed the development of purple cassava. The method used to calculate the added value is the Hayami method. The results of the study showed that there were three alternatives of processed products of purple color namely bakpia, thymus and wingko. The biggest added value of processed products is wingko with an added value of Rp. 26,561 and a ratio of 64%. The highest value supply chain added is UMKM Murakabi network with an added value of Rp. 19,152 and a ratio of 70%, while the network with added value the lowest is a retailer network with an added value of Rp 6,257 and a ratio of 28%. These results indicate that the development of purple cassava business should be done by processing purple cassava in the form of wingko.

Abstract

Pallet Industries have an important role in supporting the smooth supply chain activities. Research on risk control in the pallet industry's inbound logistics is still not widely implemented. The risk caused by activities and process of raw materials procurement in the wood pallet industry is a crucial problem that must be immediately assisted to find a model solution. This study presents a new model in risk management by applying a socio-technical system approach to identifying, evaluating, and determining risk control strategies. A case study on an wood pallet industry in East Java was presented to validate the risk management model. Results of the risk assessment show that the highest risk was loss of raw material (R23). This risk was included in the safety perspective, so transferring risk to an insurance company was recommended to mitigate the risk. The results of this study were expected to help the pallet industry in minimizing losses due to risks in the inbound logistic process.

Abstract

Investment gallery is a three parties collaboration, between IDX, securities company, and university that aims to increase the number of investors, especially from the civitas academica. However, in the past year, more than 50% Investment galleries failed to meet the growing investor target. Therefore, it is necessary to redesign an investment gallery that is more oriented to the wants and needs of investors and potential investors. through investment galleries and their intention to reinvest. Factors are generated through literature studies and interviews to customers and management of IDX and results in 12 factors. These factors were measured by 32 indicators and tested using an online and offline questionnaire of 193 respondents from 7 best investment galleries in Indonesia. The data obtained is processed by using factor analysis so as to form 5 factors: perceived image, customer experience, benefit, facilities, and response time. These results are then processed to see the relationship of each factor to the intention to re-invest. Based on multiple linear regression analysis, only 4 factors have significant effect, which are perceived image, benefit, facilities, and customer experience. The results of the study were then used to develop an investment gallery marketing strategy.

Abstract

Vehicle routing problem with simultaneous pickup and delivery (VRPSPD) is a problem of vehicle routes where the delivery and pickup of products to each consumer is conducted simultaneously. Pangkalan Agisindo Alam Mandiri is engaged in the distribution of 3 kg LPG. At present,pangkalan already has a schedule of visits to retail stores, but the visit route is still subjectively set which causes long mileage and high transportation costs. The problem of determining the route at this pangkalanis calledVRPSPD because pangkalandelivered filled  LPG tubes to retail stores and at the same time picked up empty LPG tubes to be brought back. To determine the route, one must consider the vehicle capacity and the ratio of the number of LPG tubes delivered and picked up. This research used a tabu search algorithm to get the proposed route. The steps in the tabu search algorithm includes  determination of the initial solution, the neighborhood search, intensification phase, diversification phase,  standard phase, and  interactive phase. By using the tabu search algorithm, the proposed route provided a savings of transportation costs of 13.72% rather than the initial route of the company.

Abstract

Water pump machines are electronic products that are widely used by the community. Because of the high frequency of use, this product is quickly damaged. In order to reduce the environmental impact, the ease of the product to be repaired or recycled needs to be improved, especially the dismantling process because it is the initial process to separate components. This study aims to evaluate the ease of dismantling a water pump machine based on the ease of component to be reached and the complexity of the component and product design. Evaluation begins by identifying the initial product design and the relationships between components needed to determine the order of possible product demolition and as an attribute of calculating complexity and accessibility indexes. The calculation results show that the complexity and accessibility idex values for each component are the same in all disassembly sequences because the product design does not allow for sub-assembly. The most complex components are mechanical seal, water reservoirs and lids beside the pump body. While the components that are most difficult to access are impellers, mechanical seals and rator covers.

Abstract

Research on smoked fish packaging has only focused on its functional side to increase product life. Meanwhile, research on smoked fish packaging design that focuses on improving and expanding markets has never existed. Until now, smoked fish was sold without packaging even though the amount of production continued to increase. The purpose of this study was to determine consumer preferences for the design of smoked fish packaging. With the recognition of these preferences, it is expected that the smoked fish industry players can apply it so that it can increase the sale value and the number of sales. This study uses focus group discussion as a qualitative method and conjoint analysis as a quantitative method. Color, material, shape, size, brand, and additional information is the attribute chosen at the focus group discussion as a representation of smoked fish packaging to determine the level of its preference. The results of this study indicate that brands have the highest preference compared to others (importance values 30.303%).
