Abstract

Project Based Learning (PBL) is an educational method that can make learning more tangible for students by directly relating it to their daily lives. The aim of this research is to enhance creativity through the Project Based Learning approach in Fashion Design education. This pre-experimental research utilizes a pre-test and post-test design. The study was conducted in the Fashion Design Study Program at the Social Welfare Academy (AKK) Yogyakarta during the odd semester of the 2023-2024 academic year. The research subjects were fashion design students at AKK Yogyakarta. The research instruments included portfolio results and observation sheets. Data analysis was performed using the Wilcoxon test. The results indicate that Project Based Learning positively impacts creativity in fashion design courses. The average pre-test score was 59.10, while the post-test score increased to 91.63. The Wilcoxon test analysis yielded a p-value of 0.000, indicating that the Project Based Learning method significantly influences creativity enhancement in fashion design education.

Abstract

Research on calculus has developed a lot, including fractional calculus. Fractional calculus is a branch of mathematics that transforms the orders of derivatives and integrals into rational or even real values. In finding the value of the derivative and the fractional integral, a numerical method is needed to find it, because of the difficulty if it is done using an analytical method. In this paper, we will describe the Riemann-Liouville fractional integral approach using the trapezoidal rule and Simpson's rule. We also provide an overview of the comparisons and errors that result from the two methods.

Abstract

The mathematical model has been used to understand many phenomena and natural interactions. Since including many variables and parameters, the complex models are not easy to find analytical solutions. In this paper, we analyze one of the family of Runge–Kutta method with an expansion of evaluation function. We applied the proposed method to solve ordinary differential equations problems and compared it with other well-known Runge-Kutta methods. The computation cost and accuracy for each method have been analyzed.

Abstract

Coronavirus Disease 2019 has become global pandemic in the world. Since its appearance, many researchers in world try to understand the disease, including mathematics researchers. In mathematics, many approaches are developed to study the disease. One of them is to understand the spreading of the disease by constructing an epidemiology model. In this approach, a system of differential equations is formed to understand the spread of the disease from a population. This is achieved by using the SIR model to solve the system, two numerical methods are used, namely Euler Method and 4th order Runge-Kutta. In this paper, we study the performance and comparison of both methods in solving the model. The result in this paper that in the running process of solving it turns out that using the euler method is faster than using the 4th order Runge-Kutta method and the differences of solutions between the two methods are large.

Abstract

In Indonesia, student education is increasingly advancing as part of the effort to produce competent and creative professionals. One institution focusing on vocational education in this field is AKS AKK Yogyakarta. As a vocational higher education institution, AKS AKK plays a significant role in providing relevant and applicable skills to its students. In this context, students' ability to create mood boards is considered essential, as it serves as a foundation for broader academic and creative processes. This study adopts a quantitative approach with a true experimental design. The chosen design is the Pretest-Posttest Group Design. The population of this study consists of all students in the Fashion Design program at the Social Welfare Academy (AKK) Yogyakarta during the relevant academic year. The sample was selected using a simple random sampling technique, taking into account the homogeneity of students’ initial abilities, with a total of 40 students participating in a Drawing Achievement Test. Data analysis was conducted using a t-test. The results indicate a significant influence of the ability to create mood boards on the academic performance of students in the Fashion Design program at AKS AKK Yogyakarta. Thus, it can be concluded that the ability to create mood boards has a positive contribution to enhancing students’ academic performance.

Abstract

Price fluctuations, which often occur in the agricultural sector, cause farmers to experience losses when selling prices are not balanced with production costs. The government is trying to minimize farmers' losses by issuing an agricultural insurance program. One of the problems with agricultural insurance is determining the premium that farmers must pay so as not to disadvantage the insurance company. This paper explores the price of insurance premiums associated with potato cultivation in West Java, Indonesia. In addition, this research analyzes the factors that influence prices by focusing on the relationship between potato production levels and market prices. Therefore, a comprehensive data set of potato production data and associated prices is used. Regression analysis, as a statistical technique, is used to model the relationships. The Black-Scholes method then uses the obtained result to determine insurance premiums. This method is used due to a theoretical framework for pricing options that allows selecting an option's fair price using a structured, defined methodology that has been tried and tested. The premium values that depend on the trigger value are then obtained with a range of prices between IDR 5,687,670 and IDR 18,067,953 for an insured amount of IDR 39,403,000 per contract period. The premium price range allows farmers to choose the right agricultural insurance policy. It also allows insurance companies to determine insurance premiums for potato cultivation.
