Abstract

Business activities in the agricultural sector, especially rice farming, will always be faced with a high risk of uncertainty. The risks experienced by farmers come from the natural environment, natural disasters, climate, and plant-disturbing organisms. To avoid this situation, the government is currently providing the best solution in the form of a Rice Farming Insurance program (AUTP), which is expected to provide protection against the risk of crop failure that farmers may experience. The purpose of this research is to analyze rice farmers' risk preferences in determining rice farming insurance premiums. The research method for rice farmers' risk preferences was analyzed using constant relative risk averse (CRRA) utility theory. Based on the research results, rice farmers in Majalaya District, Bandung Regency has a very risk averse risk preference. The risk preferences of farmers participating in AUTP and non-AUTP are very risk averse. The policy implications that can be explained based on the results of this study are increasing farmers' understanding regarding the description and benefits of agricultural insurance through counseling and assistance by the Agriculture Service and PT. Jasindo, so that rice farmers in Majalaya District, Bandung Regency have awareness of the benefits of insurance. Encouraging the participation of rice farmers in Majalaya District in the AUTP program can also be carried out by prioritizing rice farmers with very risk averse risk preferences.

Abstract

This study aims to produce differential calculus teaching materials using a good (valid, practical and effective) open-ended approach to improve students' critical and creative thinking skills, and compare their effectiveness with teaching materials prepared in the context of implementing the implemented curriculum. This research is research and development (Research and Development). The development models referred to are the modified Dick & Carey and Borg & Gall models. The steps in this development are researching and gathering information, developing teaching, selecting and developing teaching materials, initial trials, revisions, main trials, and final product revisions. Initial trials and main trials are carried out in a university. Product validity is validated by experts. Product practicality is assessed by product users, namely lecturers and students. Product effectiveness was tested using an inferential statistical test by looking at the significant differences in the mean of the pretest and posttest scores in terms of students' critical and creative thinking abilities. Next, the effectiveness will be compared between the control class and the experimental class. The results of the research show that the product developed is in the very valid category according to the experts, practical according to the teacher's assessment, and very practical according to the students. The resulting product is also effective, even more effective when compared to teaching materials in terms of critical and creative thinking skills student.
