Trend TSR 20 rubber prices between producing countries in Southeast Asia

Abstract

Natural Rubber is one of the world's largest commodities used for industrial needs. The price of TSR 20 rubber continues to fluctuate, which has a significant impact on some farmers in various countries. This study analyzes the price trend of TSR 20 rubber in Southeast Asia. The purpose of this study is to analyze trends and fluctuations in STR 20 rubber prices in Southeast Asia, such as Standar Thailand Rubber (STR 20), Standar Indonesia Rubber (SIR 20), Standar Vietnam Rubber (SVR 20), and Standar Malaysia Rubber (SMR 20) for 72 months from January 2017 - December 2022. This research uses trend analysis with simple linear regression method. This research uses the historical method by conducting research on a source which is then critically analyzed. Data collection techniques are obtained by tracing data and documents that have been stored by agencies including the Ministry of Agriculture, Ministry of Trade, International Rubber Study Group (IRSG), Singapore Commodity Exchange (SICOM), Association of Natural Rubber Producing Countries (ANRPC), Food and Agriculture Organization (FAO), The World Bank, and Gapkindo as well as existing literature and sites. The results obtained are positive trends where each development between countries has experienced a positive price increase, such as, STR 20 has a polynomial line equation Y = 0.0331x2 – 95,28x + 68596, then SIR 20 Y = 0.0231x2 -66,443 + 47966, SVR 20 Y = 0,0301x2 – 86,824x+ 62648, and SMR 20 Y = 0,0279x2 – 80,411x + 58010.
