Abstract
Landslides in Indonesia have caused much damage and claimed lives inland, environment, people, and property. This study aims to identify and analyze the types of landslides, the factors causing landslides, and the impacts of landslide-prone impacts in determining food security and agricultural economics. The research method used was survey and laboratory analysis. The research was conducted in the Samin Hulu Tengah River Basin (Matesih and Karangpandan Districts) Karanganyar Regency, Central Java, Indonesia. The research data were obtained using field surveys and literature studies. The research data is in the form of thematic maps of the area, data on landslides in the watershed, soil samples analysis, and survey results. The results showed that the level of landslide-prone in Karangpandan District was higher than in Matesih District. The causes of landslides were triggered by higher rainfall, higher slopes, more dominant andesite rocks. In Karangpandan, there are five types of landslides, namely Landslides, Rocks, Subsidence, Landslides, and Soilcreep. Regarding the methods of land management and food security, the analysis of the findings showed that the cultivation pattern, increasing soil fertility, landslide and water resources management had the greatest relationship with agricultural economy. Farmers who used the methods regarding landslide and water resources management had more safe and healthy access to food due to increased land quality and productivity. Therefore, it can be said that in order to increase the yield of agricultural products, increase food security and invest in this field, more support services should be provided to farmers and necessary measures should be taken for more participation and cooperation of farmers in the field of sustainable land management.
印尼的山体滑坡造成了巨大的破坏,并夺走了内陆地区的生命、环境、人员和财产。本研究旨在识别和分析滑坡的类型、导致滑坡的因素以及滑坡易发影响对确定粮食安全和农业经济的影响。所采用的研究方法是调查和实验室分析。该研究在印度尼西亚中爪哇省卡兰加亚尔县的Samin Hulu Tengah河流域(Matesih和Karangpandan区)进行。研究数据是通过实地调查和文献研究获得的。研究数据采用该地区专题地图、流域滑坡数据、土壤样本分析和调查结果的形式。结果表明,卡朗潘丹地区的滑坡易发程度高于马泰什地区。山体滑坡的原因是由更高的降雨量、更高的坡度和更主要的安山岩引发的。在卡朗潘丹,有五种类型的滑坡,即滑坡、岩石、沉降、滑坡和土壤蠕变。关于土地管理和粮食安全的方法,对研究结果的分析表明,耕作模式、提高土壤肥力、滑坡和水资源管理与农业经济的关系最大。由于土地质量和生产力的提高,使用滑坡和水资源管理方法的农民可以更安全、更健康地获得食物。因此,可以说,为了提高农产品产量、提高粮食安全并投资于该领域,应该向农民提供更多的支持服务,并采取必要措施,让农民更多地参与和合作可持续土地管理领域。
