Abstract

Introduction: The agricultural sector is a sector that depends on natural conditions so that uncertainty and risk in farming always occurs. The source of risk is predicted to continue to grow which greatly affects the total agricultural yield. Farming risk consists of production risk and price. Production risk is related to production uncertainty. Price risk is related to price fluctuations that cause losses to farmers because prices are difficult to predict. Indonesia is known for its diversity with nearly 300 ethnicities. Each ethnic group has different characteristics in behavior, language and customs. This difference is possible to influence decisions in managing a business, including in dealing with farming risks. This study attempts to analyze the behavior of rice farmers on the risk of farming among various ethnic groups in East Java and factors that influence farmer behavior towards farming risk. Methods: This research was conducted in Pamekasan, Ngawi and Pasuruan, where these three districts represent Javanese, Madurese, and Madura-Javanese ethnic assimilation. The data used are primary data collected from 49 respondents in Pamekasan Regency, 72 in Ngawi Regency and 65 in Pasuruan Regency so that a total of 186 respondents using the cluster sampling approach. Farmers' behavior towards farm risk was analyzed using the Just and Pope risk function model with the utility function approach, while the analysis of factors that influenced behavior towards farm risk was carried out using multiple regression. Results: The results of the analysis show that the behavior of rice farmers in Pamekasan District with Madura ethnic risk seekers, in Pasuruan Regency is a risk averse and in Ngawi Regency is a risk seeker. Conclusion: Regression analysis shows that differences in ethnicity of farmers affect the way rice farmers deal with farming risks

Abstract

Introduction: This study aimed to assess the physicochemical characteristics of tapioca modified by microwave heat treatment. Methods: The assessment was carried out using a one-factor Completely Randomized Design, namely microwave heat treatment with four levels of commercial tapioca. These included microwave tapioca (TMW), microwave washing tapioca (TPMW), and microwave soaking tapioca (TPRMW) with three replications. The variables observed were chemical tests including moisture and ash content, with physical characteristics such as solubility, swelling power, water, and oil holding capacity (OHC). The data obtained were assessed using MINITAB 21 analysis of variance, followed by Tukey’s test when there was a significant difference. Results: The best treatment was found to be a modification of starch using microwave heat in TPRMW, producing 8.01% moisture content, 0.13% ash content, 32.80% swelling power, 24.76% solubility, 218.50% water holding capacity (WHC), and 176.93% OHC. Conclusion: Modification treatment using microwave heat caused chemical and physical changes in tapioca to experience a decrease in moisture content, ash content, swelling power, solubility, and OHC compared to natural tapioca. However, this treatment increased WHC, which was specifically observed for TPRMW.
