Abstract

This study aims at developing a kinetics model of changes in tomatoes quality during storage. Samples were stored at temperature of 6, 15, and 28 °C. Quality parameters measured were total carotene, citric acid, and vitamin C. On the development of kinetic models of quality parameter changes the k values of total carotenoids, citric acid, and vitamin C were 0.075, -0.008, and 0.042 at 6 °C, 0.056, -0.029, and 0.049 at 28 °C, as well as 0.125, -0.039, dan 0.044 at 28 °C, respectively. Activation energy of the decrease of citric acid was 47.91 kJ/mol, whereas for total carotene and vitamin C were 17.83 kJ/mol dan 0.96 kJ/mol. The coefficient of determination (R2) of the quality content between observation and prediction were 0.70-0.96. Keywords: Kinetics, total carotene, citric acid, vitamin C, tomato

Abstract

The rapid development of technologies affects the financial technology sector, especially e-money in Indonesia. This research aims to analyze the determinant from intention and use behavior of financial technology (e-money) using UTAUT2 as the model. This research took place in Jabodetabek, with a total sample of 300 people as the respondents. The purposive sampling method is used as the sampling method in this study. The scale which is used in this study is the Likert scale with a range of 1-5. Data were analyzed using descriptive and Structural Equation Modeling (SEM). The results show that performance expectations, effort expectancy, social influence, facilitation conditions, and habits are factors that influence the intention and use of e-money. On the other hand, hedonic motivation and price value do not affect behavioral intention. It indicates that using financial technology is a must and not depend on user motivation or the price of the technology. These results provide implications about several factors as the determinant of e-money for stakeholders to develop the strategy for e-money based on the most influential factor that affects consumers as users. While developing e-money technology, the developer should take into account factors such as performance expectations, effort expectancy, social influence, facilitation conditions, and habits.

Abstract

Hard and crunchy are specific characteristics of fried product prefered by consumer. To have texture of crunchy product being suitable with consumer taste, it is necessary to observ characteristic change of raw material and frying condition. In frying process, the changes of hardness and crunchiness characteristics of food occur. These changes are predicted caused by free water vaporization and the decrease of starch content in food. The objective of this research is to develop mathematical model of hardness and crunchiness changes as the function of water and extract content degradation. Sample of the research is jack fruit fried in the temperature of 70–100° C, duration of 15–60 minutes, and pressure of 80–90 kPa. The parameters observed are hardness and crunchiness, water and starch content before and after frying. The result showed that hardness and crunciness change as the function of water vaporization and the decrease of starch content can be used to predict hardness and crunciness of product during vacuum frying.

Abstract

Social, economic, institutional, and cultural conditions become the basis of education and provide benefits for science to formulate the introduction of regional potential, regional designations, program development carried out by villages, and routine activities (learning, research, and community service) by students and lecturers of the Faculty of Agriculture Tidar University which has an interest in developing Sidorejo Village, Bandongan District. The research objective is to create an embryonic center for local community-based education in strengthening rural areas that are progressing efficiently, effectively, and sustainably as a form of university connectivity with the local community. This research focuses on identifying the area's potential in a careful village, with a qualitative research method using an ex post facto comparative clause through a social, ethnographic approach. The research was conducted using a purposive sampling technique consisting of village officials, community leaders, youth organizations, family empowerment and welfare, arts and culture actors, business actors, and planning faculty development planners as many as 20 respondents. The results of the study are in the form of identification findings that can be used as objects of community social mapping projections, needs, essential potential, human resource capabilities, institutions, local culture, infrastructure, economy, natural resources, and agriculture to design rural areas to become centers of local community-based education in strengthening, developing and tri dharma of higher education in the fields of agriculture, plantation, animal husbandry, fisheries, and social entrepreneurship.

Abstract

Cryptography is one of the security techniques that secure information confidentiality and information integrity while electronic transaction processing. There are three kinds of cryptograpy protocols, Symmetric Algorithms, Asymmetric (Public Key) Algorithms, and Cryptographic Protocols. Elliptic Curve Cryptography (ECC) is one of the public key encryption. ECC requires high computation for solving arithmetic operations.Finite field has important role in ECC implementation, which curve operations requires finite field. Finite field has several arithmetic operations, add, multiplication, squaring, and invers. There are many method or algorithm for each arithmetic operation. Finite field can be representation in prime field GF(p) and binary field GF(2m). There are two representation in binary field, polynomial basis and normal basis. This research presents implementation of arithmetic operation algorithms for adding, multiplication, squaring, and invers on polynomial basis with maximum key 299 bits. Besides that, this research presents the measurement of algorithm performance based on processing time and memory usage. Keywords — cryptography, elliptic curve, finite field, polynomial basis, binary field
