Abstract

It is expected that the COVID-19 pandemic provides a significant impact on food price volatility in many products including sugar. The paper aims to analyze the price dynamic of sugar before covid (1st August – 2nd March 2020) and during the covid outbreak (3rd March – 31th August 2021) in all provinces in Indonesia by using the t-test and ARCH GARCH model. Based on Augmented Dickey-Fuller analysis before and during covid, the prices of sugar in Indonesia were stationary at the “first difference”. The results reveal that the prices of sugar in all provinces in Indonesia before covid was lower compared to during the COVID-19 pandemic. According to ARCH GARCH results, sugar prices were much more volatile in Riau, Jambi, West Java, East Nusa Tenggara, West Kalimantan, South Sulawesi, Central Sulawesi, and West Papua. As such, the government should focus to reduce the price volatility of sugar in these provinces. Keywords: ARCH GARCH, COVID-19, sugar prices, stationarity, volatility

Abstract

Harga daging sapi di Indonesia mengalami fluktuasi dengan besaran yang berbeda antar provinsi. Hal ini diakibatkan oleh permintaan yang tidak dapat dipenuhi oleh produksi domestik terutama saat periode masa pandemi Covid 19 yang sedang terjadi di Indonesia. Kenaikan ini salah satunya disebabkan oleh pandemi Covid-19 yang sedang terjadi di dunia terutama di Indonesia. Letak pusat produksi dan konsumsi yang berbeda cenderung menyebabkan masalah distribusi daging sapi. Biaya transportasi yang tinggi menyebabkan harga di provinsi provinsi-provinsi yang jauh dari pusat produksi daging sapi di Jawa Timur, Nusa Tenggara Timur, dan Nusa Tenggara Barat mengalami peningkatan. Pembatasan yang bertujuan untuk mencegah penyebaran Covid-19 yang diselenggarakan oleh pemerintah juga memperparah permasalahan distribusi daging sapi yang kemudian berujung pada fluktuasi dan disparitas harga daging sapi.
