An Agri-food Supply Chain Model to Empower Farmers for Supplying Deteriorated Product to Modern Retailer

Small-scale vegetables farmers have to deal with marketing and low selling price problems although they produce good quality of vegetables. The low prices are mostly because of the market information asymmetry. An agri-food supply chain (ASC) model that involves the corporate social responsibility (CSR) activities to empower the farmers as qualified supplier for modern retail (MR) is proposed to overcome the problems. The CSR activities are designed to enhance business skills and improve the quality of vegetables distribution system. For farmers, quality improvement of vegetable is expected to increase supply of vegetable to MR, whereas for MR to increase selling price and lengthen deterioration time of vegetable thus reducing the risk of unsold vegetable to consumer. Multi-objective optimization programming is developed to determine the amount supply, level of farmers training skills, quality improvement target, and the CSR total cost. The results show that both farmers and MR gain benefit from CSR activities although MR must allocate some amount of budget as CSR cost.

A Supplier-Manufacturer Model for Procurement Plan in Export Oriented Furniture Industry with Sustainability Considerations

Due to limited supply of high quality of teak log as raw materials for export oriented furniture industry in Indonesia, procurement plan becomes a critical operation. The furniture industry (manufacturer) buys high quality teak log from Perum Perhutani (supplier), a state-owned forestry company that has responsibility not only to supply teak logs but also to keep the environmental and social role of the forest in Indonesia. The manufacturer should also consider sustainability due to the demands of the stakeholders. This study proposes a relationship model between supplier and manufacturer for procurement plan and formulated as Goal Programming to get the most favorable solution considering economical, environmental, and social aspect both of supplier and manufacturer. The results show that the model can be used to determine the decision variables considering sustainability aspects.

Supply chain risk management of newspaper industry: A quantitative study

The newspaper industry has several distinctive features that make it stands out from other industries. The strict delivery deadline and zero inventory led to a very short time frame for production and distribution. On the other hand, there is pressure from the newsroom to encourage the start of production as slowly as possible in order to enter the news, while there is pressure from production and distribution to start production as early as possible. Supply chain risk management is needed in determining the best strategy for dealing with possible risks in the newspaper industry. In a case study of a newspaper in Surakarta, quantitative approaches are made to the newspaper supply chain risk management by calculating the expected cost of risk based on the magnitude of the impact and the probability of a risk event. From the calculation results obtained that the five risks with the highest value are newspaper delays to the end customer, broken plate, miss print, down machine, and delayed delivery of newspaper content. Then analyzed appropriate mitigation strategies to cope with such risk events.The newspaper industry has several distinctive features that make it stands out from other industries.

The use of importance and performance analysis (IPA) to evaluate effectiveness of the forward auction market agro commodities: A case study

The empowering auction market for commodities in East Java Province is one of five auction market revitalization programs conducted by the Republic of Indonesia c.q. Ministry of Trading started in 2014. One of the districts in East Java Province, namely Magetan District utilizes the commodity auction market to improve the competitiveness of their agricultural industry by shortening the supply chain. The Magetan District needs to evaluate their support for farmers or farmer groups to participate in the forward auction market (FAM). Implementation of the FAM commodities is divided into three main processes, namely pre-auction, auction, and post-auction. The auction market is organized to shorten the trading chain. Implementation of the FAM requires good planning, among Seller (namely Farmer or Farmer Group), organizer of Auction (namely Commodity Auction Company), Buyer, and Local Government (namely the farmer facilitator). This article is aimed to develop the instrument of a Performance Measurement Model Using Important and Performance Analysis (IPA) for Improving the FAM Effectiveness of Agro Commodity from Magetan District with Supply Chain Management approach. IPA is implemented at pre-auction, auction, and post-auction. The IPA model results in the diagram to decide the strategies in improving the FAM effectiveness, and then it can encourage farmers to improve welfare and realize the competitiveness of the auctioneer.The empowering auction market for commodities in East Java Province is one of five auction market revitalization programs conducted by the Republic of Indonesia c.q.

The dynamic simulation model of soybean in Central Java to support food self sufficiency: A supply chain perspective

Consider food become one of the basic human needs in order to survive so food sufficiency become very important. Food sufficiency of soybean commodity in Central Java still depends on imported soybean. Insufficiency of soybean because of there is much gap between local soybean productions and its demand. In the year 2016 the shortage of supply soybean commodity as much 68.79%. Soybean is an important and strategic commodity after rice and corn. The increasing consumption of soybean is related to increasing population, increasing incomes, changing of healthy life style. The aims of this study are to determine the soybean dynamic model based on supply chain perspective, define the proper price of local soybean to trigger increasing of local production, and to define the alternative solution to support food self sufficiency. This study will capture the real condition into dynamics model, then simulate a series of scenario into a computer program to obtain the best results. This study will be conducted the following first scenario with government intervention policy and second without government intervention policy. The best solution of the alternative can be used as government consideration for governmental policy. The results of the propose scenarios showed that self sufficiency on soybean can be achieved after the next 20 years by increasing planting area 4% and land productivity 1% per year.Consider food become one of the basic human needs in order to survive so food sufficiency become very important.
