Abstract

The Human Development Index (HDI) is an indicator used to assess the success of human development. The Human Development Index (HDI) is used to measure the impact of efforts to improve basic human capital capabilities. Based on BPS data, the HDI in East Java has consistently increased and has reached a high category, however, when compared to DKI Jakarta and DI Yogyakarta, the HDI in East Java is still relatively low. This study aims to determine the factors that influence the HDI in East Java Province. The research data are the 2024 HDI data for East Java Province obtained from the BPS of Lamongan Regency and the BPS website of East Java Province. This study uses the multiple linear regression method with RStudio software. Based on the results of the study, the multiple linear regression model with HLS, RLS, UHH, and GK factors has an influence of 97.94% on the HDI in East Java Province, while the TPT does not show a significant influence on the HDI in East Java Province.

Abstract

The Javanese calendar has been in use since July 8, 1633 AD, during the time of Sultan Agung. In the Javanese calendar, there is a cycle called kurup. Aboge is one of the kurup in the Javanese calendar, the third kurup after Awahgi and Amiswon. Currently, the Javanese calendar has reached the fourth circle, namely Asapon. Even though it is kurup, Aboge is special because Aboge is seen as a religious sect. Regarding determining the beginning of fasting and other religious holidays, Aboge has its own method based on the Javanese-Aboge Calendar, better known as the Aboge Calendar. This research was made to explain the inconsistency in determining the start of fasting calculated by the Aboge and Asapon calendars, compared to government regulations. The research method is a literature study and a case study surveying government regulation regarding the beginning of fasting and Eid al-Fitr. The study results show that both the Aboge Calendar and the Asapon Calendar are not appropriate when used as a guide for determining the implementation of religious holidays.

Abstract

Since 2016, the Government of the Republic of Indonesia has implemented the Rice Farming Insurance (AUTP) program as mandated by law. In the context of Central Java, with its large Muslim population and successful implementation of sharia economics, it is necessary to develop an AUTP model based on sharia principles. This research aims to create an AUTP model by applying sharia principles (Sharia AUTP or AUTPS) based on a rainfall index and to determine the amount of contribution and compensation within the AUTPS framework. The research methodology employs literature study and model development through stages of planning, analysis, pre-design, actuarial calculation, and final design. The research data comprises rainfall and rice production data from Brebes Regency for the years 2018–2022. The novelty of this research lies in the application of sharia principles and the use of a rainfall index to replace crop failure-based insurance. Consequently, the actuarial calculation for implementing contributions and compensation is based on the rainfall index. The contribution amount is calculated using the Black-Scholes Cash-or-Nothing Put Option equation, while compensation is calculated using the historical burn analysis method. The research results in a proposed rainfall index-based AUTPS model, where the contribution amount is determined based on rainfall percentiles, and compensation payments are categorized as maximum compensation, partial compensation, or no compensation. The mechanism for managing contributions (premiums) follows sharia principles and yields two types of AUTPS: AUTPS-R (without a savings element) and AUTPS-RI (with a savings element). The recommendation from this research is the need to pilot the developed concept in collaboration with a sharia insurance company before it is adopted as a policy by the Regional Government of Central Java Province.
