One model that can be used to analyze the relationship between the two variables is the copula. However, apart from rainfall, global climate phenomena such as the El Nino-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD) also have an inﬂuence on forest and land ﬁres. Therefore, this study analyzes and models the copula-based co-distribution between rainfall and burned area by partitioning the data based on ENSO and IOD phenomena. The method used is copula-based joint distribution analysis which is estimated using the Inference of Function for Margins (IFM) method. Several copula functions are used to form joint distributions, such as Gaussian, student’s t, Clayton, Gumbel, Frank, Joe, Galambos, BB1 (Clayton-Gumbel), BB6 (Joe-Clayton), BB7 (Joe-Gumbel), and BB8 (Joe-Frank). The results showed that the highest correlation to the burned area occurred for the two months cumulative rainfall data based on the Kendall-Tau correlation. Each ENSO and IOD condition has diﬀerent characteristics, indicated by the diﬀerences in the selected univariate distribution and copula function. Probabilities of burning areas are higher when rainfall is low. In addition, the higher the ENSO and IOD indices, the higher the probability of burned area, during low rainfall. Based on the conditional probabilities, the Positive IOD condition has relatively more signiﬁcant inﬂuence than the Moderate-Strong El Nino. Apart from the Moderate-Strong El Nino and Positive IOD, another condition that has a conditional probability for a relatively high is Weak El Nino conditions. Other conditions, such as La Nina, normal ENSO, negative IOD, and Neutral IOD, have a conditional probability of a very small burn area.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45441010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paddy farm insurance is expected to be capable of being utilized as a solution to reduce the risk of crop failure that may be encountered by farmers. This research was intended to determine the average value and factors that provide an inﬂuence on the willingness of farmers to pay, and probability for farmers to pay the paddy farm insurance premium. Willingness to Pay (WTP) value may be determined through the Contingent Valuation Method (CVM). More-over, the factors that provide an inﬂuence on the willingness of farmers to be involved and probability value for farmers to pay premiums may be analyzed by Logistic Regression. Referring to the research results, the average value of the willingness to pay premiums was amounted to Rp 31.973,73/Ha/MT. This value was found to be 11.18% less than the current premium determined by the government. Major factors that were considered capable of inﬂuencing farmers to pay premium is consisted of the area of agricultural land and farm-ing experience, with probability value of farmers to pay premium is 0,1414.","PeriodicalId":53096,"journal":{"name":"Jurnal Matematika Integratif","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43993584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
