Abstract

This study aims to identify the mapping, measure performance, and analyze problems in the structure of rice supply chain management on the supplier network phase in South Sumatra. Afterward, the result of this study is used as the basic consideration to improve the rice supply chain performance on indicators that have problems. Data collection was conducted by direct interview, questionnaire, and observation. This study used descriptive qualitative and several analysis tools as the data such as Supply Chain Operation Reference Model (SCOR), Analytical Hierarchy Process (AHP), Objective Matrix (OMAX) and Traffic Light System (TLS). According to the rice supply chain mapping on supplier network phase, there are three rice supply chains. Based on the interview, the farmers’ main problem as the main producers of the rice supply chain in South Sumatra is the limitation of unhusked rice price information in harvesting in the financial flow of rice supply chain. Based on the weighting result by OMAX scoring system, the total index value is 7.28, or in the yellow category which means that the performance of LICM rice- industry company in South Sumatra has not achieved the expected performance in terms of rice supply chain even though the result is close to the pre-determined target.

Abstract

Price behavior is an indicator for market efficiency. The reseach is conducted: (i) to examine the relationships between riil price for rice at retail level and riil price for rough rice at producer level, (ii) to examine the relationships between riil price for rice at retail level and riil price for impor rice. The causality is analysed by error correction representation, and the asymmetry of price transmmision is analysed by error correction model approach. It is used monthly time series data from 1998 – 2008. Results of the research show that: (i) the riil price for rice at retail level is integrated to the riil price for rough rice at producer level in the longrun; (ii) there is a causality direction from riil price for rice at retail level to riil price for rough rice at producer level, and no reverse, (iii) the price transmmision of relationship between riil price for rice at retail level and riil price for rough rice at producer level is asymmetry. Price adjusment of rough rice at raising price is slower than at falling price.Key words: Asymmetry Price Transmission, Rice, Lampung Province
