Rarity of Joint Probability Between Interest and Inflation Rates in the 1998 Economic Crisis in Indonesia and Their Comparison Over Three Time Periods
Full text linkAfter more than twenty years, there has been no economic crisis as severe as 1998 based on inflation and interest rates. It is interesting to compare the conditions before and after the 1998 crisis and the economic conditions in the last decade in Indonesia. Therefore, this study aims to analyze the relationship between inflation and interest rates using a copula-based joint distribution. The joint return period of the 1998 economic crisis is estimated from this joint distribution. The results showed that the Gumbel copula is the most suitable bivariate copula to construct a joint distribution between inflation and interest rates in 1990-2019, with an upper tail dependency of 0.6224. Moreover, the joint return period between inflation and interest rates more severe than 1998 is 389 years with a 95% confidence interval of [47, ∞] years. This result is uncertain because many factors affect inflation and interest rates. The inflation rate decreased after the 1998 crisis. Meanwhile, in the last decade, the inflation and interest rates were much lower than in the two previous periods

Stingray (Neotrygon orientalis) population structure based on catch data in Nusantara Fishery Port (Pelabuhan Perikanan Nusantara/PPN) Brondong, Lamongan
Full text linkStingray is a type of fish included in the Elasmobranchii class that has high economic potential. This study aims to determine the sex ratio, growth rate, length-weight relationship, condition factor, mortality and exploitation rate of stingray (Neotrygon orientalis) in PPN Brondong, Lamongan. Samples N. orientalis collected every week starting from October 1, 2019 until January 2021 and weighed in total body weight (gram) and measured in total body length (cm) then sex was identified based on macroscopic characteristics of gonads. The results showed that the sex ratio of N. orientalis was 1.4 : 1. Length growth value (K) of male and female N. orientalis are 0.0285 and 0.0233, respectively, which show a slow growth time to reach the asymptotic length (K≤ 0.5). Based on the analysis of the relationship between length and weight, the results show that b value are 1.9394 and 2.2023 in male and female N. orientalis, respectively, which means length growth rate faster than weight growth (b< 3, negative allometric). N. orientalis are included in the category of flat (thin) fish with condition factor values ranging from 0.2462-3.9227. The total, natural, and fishing mortality rate were 0.395, 0.177, and 0.218, respectively. The exploitation rate is 0.551 where the value has exceeded the optimum value 0.5, which means that N. orientalis landed at the PPN Brondong, Lamongan has indicated overfishing caused by excessive fishing activity
