| Abstrak/Abstract |
Dieng Volcanic Highland is one of the most intensive potato agricultural land, as well as frost disaster prone area. Frost indicated by appearance of frozen dew on ground or vegetation surface due to cold temperatures during dry season. Frost causes damage to leaf tissue in potato plants, resulting crop failure and losses of up to tens of millions. Disaster management needs to be assess in order to achieve Disaster Risk Reduction (DRR) on agricultural land. This research aims to analyze level of frost hazard and analyze disaster mitigation plans for potatoes farmland. Research was conducted in Dieng Village, Wonosobo and Dieng Kulon Village, Banjarnegara. Method to assess hazard level was performed by spatial mapping technology using ArcGIS and comprehensive analysis using system thinking diagram through combinations of geomorphology, landuse, and climate aspects. Results shows that frost distribution only appear on alluvial plains than mountain slopes. Air inversion at night near plain's surface causes plains to cool faster than surrounding slopes. Hazards map shows that 110 hectares include frost-prone areas, which are 69 hectares are experience agriculture losses, while 41 hectares are not experience losses. Recommended mitigation plans to reduce frost impacts, among others; A) Shifting into frost resistant commodities, B) Modified cropping system, C) Modified frost formation by installation of furnaces, wind blowers, and sprinkle irrigation, D) Covering farmland with nets or mulch, E) Using a frost-based planting calendar, and F) Implementing climate insurance system. Through this research is expected to create climate-resilient agriculture in Dieng Volcanic Highland. |
