Abstract

Agricultural insurance is a form of adaptation that farmers can do to deal with extreme climate such as drought. Climate index insurance is one of agricultural insurance that uses climate parameter to determine payment for farmers. Climate parameter which is used in this analysis is rainfall and conducted in Brebes Regency. The analysis uses rainfall data in millimeters (mm) during decade days that calculated in area which has same rainfall pattern called ZOM, from 2008 to 2018. The result of climate index analysis using Historical Burn Analysis produce two values, namely trigger value and exit value. Trigger and exit value determine how much payment for the insurance claim based on rainfall data, which trigger is the threshold for the payment of insurance claim while exit value is the threshold for full payment. The results showed that in ZOM 95 trigger value is 18.7 mm and exit value is 4 mm, in ZOM 96 trigger value is 18.3 mm and exit value is 1.3 mm, in ZOM 97 trigger value is 19.8 mm and exit index is 3.5 mm, in ZOM 103 trigger value is 14.8 mm and exit value is 3.0 mm, in ZOM 105 trigger value is 26.3 mm and exit value is 8.0 mm. The value of trigger and exit is valid in window period, which starts from July to September.

Abstract

Peningkatan konsentrasi gas rumah kaca telah menyebabkan perubahan pada kejadian iklim ekstrim. Penelitian ini menggunakan skenario RCP 4.5 sebagai skenario perubahaan iklim masa mendatang untuk mengetahui tren indeks suhu dan curah hujan ekstrim periode 2021-2050 di Kota Banjarbaru. Data suhu maksimum, suhu minimum dan curah hujan harian hasil proyeksi tahun 2021-2050 diolah dengan Software RClimDex sehingga didapatkan data indeks temperatur dan hujan ekstrim. Indeks-indeks tersebut merupakan indeks iklim ekstrim yang ditetapkan oleh ETCCDMI yang terdiri atas TN90p, , TX90p, TNn, TNx, TXn, TXx, TMAXmean, TMINmean, RX1day, RX5day, SDII, CDD dan CWD. Hasil penelitian ini menunjukkan bahwa diproyeksikan pada 2020-2050 tren suhu udara akan meningkat signifikan di kota Banjarbaru terutama suhu udara minimum selanjutnya pola prespitasi juga mengalami peningkatan terutama akumulasi curah hujan 5 hari berturut-turut. Meningkatknya jumlah hari kering dan berkurangnya jumlah hari basah, serta semakin tinggi akumulasi curah hujan harian namun hari basah yang sedikit akan menghasilkan curah hujan harian yang tinggi (ekstrim) setiap kejadian hari basah. Kata kunci: banjarbaru, curah hujan, ekstrim, suhu. ABSTRACT  Increased concentrations of greenhouse gases have caused changes in extreme climate events. This study uses the RCP 4.5 scenario as a future climate change scenario to determine the temperature index and extreme rainfall trends in the 2021-2050 period in Banjarbaru. Data of maximum temperature, minimum temperature and daily rainfall projection results in 2021-2050 are processed with RClimDex Software so that the temperature and extreme rain index data are obtained. The indices are extreme climate indices determined by ETCCDMI consisting of TN90p, TX90p, TNn, TNx, TXn, TXx, TMAXmean, TMINmean, RX1day, RX5day, SDII, CDD and CWD. The results of this study indicate that it is projected that in 2020-2050 air temperature trends will increase significantly in the city of Banjarbaru especially the minimum air temperature then the pattern of prespitations will also increase especially the accumulation of rainfall for 5 consecutive days. Increasing the number of dry days and decreasing the number of wet days, as well as the higher accumulation of daily rainfall but a small wet day will produce high daily rainfall (extreme) every event of a wet day. Keywords: banjarbaru, extreme, temperature, rainfall.
