      Abstract
      Kopi robusta merupakan komoditas ekspor strategis Indonesia yang harganya dipengaruhi dinamika pasar global. Penelitian ini bertujuan menganalisis integrasi pasar, karakteristik dan keterhubungan volatilitas dinamis, serta efektivitas lindung nilai antara pasar spot domestik dan pasar futures ICE London selama 2014–2025. Data bulanan harga spot tingkat pedagang pengumpul dan harga futures dianalisis menggunakan uji kointegrasi Johansen, VAR dalam diferensiasi pertama, uji kausalitas Granger, serta model DCC-GARCH bivariat untuk mengestimasi rasio lindung nilai optimal dinamis dan efektivitas lindung nilai. Hasil penelitian menunjukkan bahwa kedua pasar tidak terkointegrasi dalam jangka panjang, tetapi terdapat kausalitas satu arah dari harga futures ke harga spot yang mengindikasikan peran ICE London sebagai pemimpin harga. Persistensi volatilitas pasar spot sebesar 0,7136, lebih rendah daripada pasar futures sebesar 0,9973. Korelasi bersyarat rata-rata kedua pasar sangat tinggi, yaitu 0,8697, dan meningkat dari 0,8233 pada 2014–2016 menjadi 0,9164 pada 2023–2025. Strategi lindung nilai dinamis menghasilkan rasio lindung nilai optimal sebesar 1,1028 dan efektivitas lindung nilai sebesar 77,01%, meningkat dari 54,75% pada fase El Niño menjadi 90,14% pada fase krisis iklim global. Temuan ini menunjukkan bahwa kontrak futures ICE London efektif untuk memitigasi risiko harga, terutama ketika volatilitas pasar meningkat.
       
      Robusta coffee is a strategic Indonesian export commodity whose price is influenced by global market dynamics. This study examines market integration, volatility characteristics and dynamic interconnectedness, and hedging effectiveness between the domestic spot market and the ICE London futures market during 2014–2025. Monthly collector-level spot and futures prices were analyzed using the Johansen cointegration test, a VAR model in first differences, the Granger causality test, and a bivariate DCC-GARCH model to estimate the dynamic optimal hedge ratio and hedging effectiveness. The results show that the two markets are not cointegrated in the long run. However, unidirectional causality from futures to spot prices indicates the role of ICE London as the price leader. Spot-market volatility persistence was 0.7136, lower than the futures-market persistence of 0.9973. The average conditional correlation between the two markets was very high at 0.8697, increasing from 0.8233 in 2014–2016 to 0.9164 in 2023–2025. The dynamic hedging strategy produced an optimal hedge ratio of 1.1028 and hedging effectiveness of 77.01%. Hedging effectiveness increased from 54.75% during the El Niño phase to 90.14% during the global climate crisis phase. These findings demonstrate that ICE London futures contracts effectively mitigate price risk, particularly during periods of heightened market volatility.
