Abstrak: Zone based area yield scheme in crop insurance is proposed to be an alternative policy to improve crop insurance in Indonesia, MPCI. Based on historical data, we have found that the use of province based for the zone area yield scheme is not ideal. The new cluster-based, that is lower disaggregate of province, results the smaller ratio Sw/Sb than province-based. Using Ward-like hierarchical method, it does not only utilize the average of paddy productivity which becomes a new potential to obtain the critical yield index of the zone, but also the Queen contiguity matrix by regency/municipality to cluster similar characteristics of farmers. The areas formed are three clusters on each West Java, Central Java, and East Java, two clusters on Banten, and DI Yogyakarta as a whole group. In addition, to facilitate the overview of the characteristics of clusters, we also classify the 12 clusters formed in Java into three levels of productivity which are reviewed nationally. It tends to have low (8.33%), middle (50%), and high (41.67%) productivity. The volatility rates of each clusters are also compared to the control limit of risk for its classified level, as the consideration of using over ten years paddy productivity data. The 12 clusters in Java are assumed to be controlled, because all clusters have volatility within their control cluster limit. The controlled risk of the clusters implies that the change in the critical yield index, which has been predicted in this paper based on regencies/municipalities productivity paddy from 2007 to 2018, in the next few years should not be extreme. This affects the premium rate making of conducting a cluster-based area yield scheme. As we have found, cluster-based area yield scheme in crop insurance is proposed to be an alternative policy to improve crop insurance in Indonesia. Developing clusters in order to group similar farmers or farmer groups can minimize heterogeneity yield as the basis of risk the and increase risk-management effectiveness. Using Bootstrap generated data of surveyed area in Java, the standard risk measure of extreme event (tail-value-at-risk) in the crop loss also shows that insurance company should retain smaller amount of indemnity as cluster scheme is applied. On top of that, lower bound of Two Sigma could be considered as an alternative of critical yield index. This technique provides lowest pure premium and standard deviation, which are obtained from its indemnity, among other methods.

Judul: Analisis Risiko Produksi Usahatani Padi sebagai Dasar Pengembangan Asuransi Pertanian (Kasus: Desa Sukaratu, Kecamatan Gekbrong, Cianjur)
Abstrak: Rice is one of the superior agricultural commodities in Indonesia, because the majority of Indonesia's population consumes rice as the main carbohydrate source. Therefore, rice development strategy is needed in addition to increasing the productivity of rice plants, as well as to protect the welfare of farmers as the farm perpetrators from the threat of crop failure risk. Insurance mechanism is one of risk management mechanisms that can protect the welfare of farmers. Sukaratu Village, Sub-district Gekbrong is one of villages in Cianjur that has rice as its agricultural primary commodity. The purpose of this study is to identify the source, probability and risk impact from rice commodity in the village, as well as to determine the ideal premium to be applied in agricultural insurance mechanism. The main source of risk which found in the Sukaratu village is plant pests such as pests and plant diseases, as well as the weather factors. The analysis result using the z-score indicates the probability of the risk by 3.8%. While the results of the analysis using the VaR method shows the impact risk amounted to Rp7 682 020-. Premium value obtained through the method of class rating is Rp390 222.-.
