Abstract

Chemistry learning is still less active which can be seen t students tend to be passive and less enthusiastic in learning. Students participate in learning activities with less enthusiasm and tend to wait for explanations from the teacher. One of the solutions used to overcome this is the cooperative learning model and the use of padlet application media. The purpose of this study was to find out the application of cooperative learning and padlet application media in class XI MIPA 3. The research sample was students in class XI MIPA 3 SMA N 1 Mirit, Kebumen consisting of 36 students. The research was conducted in 3 meetings. This type of research is quantitative research using descriptive analysis. Screening data through pretest and posttest value data. The results showed that learning using cooperative learning and padlet applications increased 30.94% of student achievement in class XI MIPA 3 SMA N 1 Mirit.

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

Ruin is one of the risks that insurance companies may face. Therefore, modeling the probability of ruin is a crucial aspect of risk management. This study aims to model and analyze the probability of ruin in insurance companies using integro-differential equations, assuming that the claim size follows a mixtures of two exponential distributions. The research methods are literature study and numerical simulation with phyton. Numerical calculations were performed using Python programming, and the results are presented in tables and graphs to facilitate analysis. The model is applied to three different cases. The findings indicate that the probability of ruin is inversely proportional to the initial capital and premium loading, while it is directly proportional to the expected value of claims. In other words, the probability of ruin decreases significantly as the initial capital and premium loading increase, whereas it increases as the expected value of claims rises. Therefore, the greater the surplus of an insurance company, the lower the probability of ruin.

Abstract

Penelitian ini membandingkan tiga definisi utama turunan fraksional, yaitu Riemann–Liouville, Caputo, dan Konformabel, dalam pemodelan sistem dinamis yang melibatkan efek memori. Populasi kajian adalah operator turunan fraksional sebagai generalisasi kalkulus klasik berorde bukan bilangan bulat. Intervensi dilakukan melalui pendekatan analitik dan numerik, meliputi kajian sifat dasar operator, analisis eksistensi solusi, dan penerapannya pada persamaan diferensial fraksional linear sederhana. Perbandingan difokuskan pada kesesuaian terhadap sifat kalkulus klasik, bentuk solusi, dan karakter peluruhan sistem. Hasil menunjukkan bahwa turunan Riemann–Liouville dan Caputo menghasilkan solusi berbasis fungsi Mittag–Leffler dengan peluruhan lambat, sehingga sesuai untuk fenomena dengan memori jangka panjang, sedangkan turunan Konformabel menghasilkan solusi eksponensial dengan peluruhan lebih cepat dan efisiensi komputasi yang lebih tinggi. Rentang waktu kajian difokuskan pada orde fraksional α = 1/2 sebagai representasi perilaku umum ketiga definisi. Temuan ini menegaskan bahwa pemilihan operator fraksional harus disesuaikan dengan tujuan analisis dan konteks aplikasi, khususnya antara kebutuhan representasi efek memori dan efisiensi analitik

Abstract

Conjugate Gradient (CG) method is a technique used in solving nonlinear unconstrained optimization problems. In this paper, we analysed the performance of two modifications and compared the results with the classical conjugate gradient methods of. These proposed methods possesse global convergence properties for general functions using exact line search. Numerical experiments show that the two modifications are more efficient for the test problems compared to classical CG coefficients.

Abstract

Fractional calculus is related to derivatives and integrals with the order is not an integer. Fractional Black-Scholes partial differential equation to determine the price of European-type call options is an application of fractional calculus in the economic and financial fields. Laplace decomposition method is one of the reliable and effective numerical methods for solving fractional differential equations. Thus, this paper aims to apply the Laplace decomposition method for solving the fractional Black-Scholes equation, where the fractional derivative used is the Caputo sense. Two numerical illustrations are presented in this paper. The results show that the Laplace decomposition method is an efficient, easy and very useful method for finding solutions of fractional Black-Scholes partial differential equations and boundary conditions for European option pricing problems.

Abstract

Extreme distribution is the distribution of a random variable that focuses on determining the probability of small values in the tail areaof the distribution. This distribution is widely used in various fields, one of which is reinsurance. An outbreak catastrophe is non-natural disaster that can pose an extreme risk of economic loss to a country that is exposed to it. To anticipate this risk, the government of a country can insure it to a reinsurance company which is then linkedto bonds in the capital market so that new securities are issued, namely outbreakcatastrophe bonds. In pricing, knowledge of the extreme distribution of economic losses due to outbreak catastrophe is indispensable. Therefore, this study aims to determine the extreme distribution model of economic losses due to outbreak catastrophe whose models will be determined by the approaches and methods of Extreme Value Theory and Peaks Over Threshold, respectively. The threshold value parameter of the model will be estimated by Kurtosis Method, while the other parameters will be estimated with Maximum Likelihood Estimation Method based on Newton-Raphson Iteration. The result of the research obtained is the resulting model of extreme value distribution of economic losses due to outbreak catastrophe that can be used by reinsurance companies as a tool in determining the value of risk in the outbreak catastrophe bonds.

Abstract

Since the early 1990s, a slew of chaotic-based communication systems have been proposed, all of which take advantage of chaotic waveform properties. The inspiration stems from the substantial benefits that this form of nonlinear signal offers. Many communication schemes and applications have been specifically designed for chaos-based communication systems to achieve this goal, with energy, data rate, and synchronization awareness being taken into account in most designs. However, non-coherent chaos-based systems have recently received a lot of attention in order to take advantage of the benefits of chaotic signals and non-coherent detection while avoiding the use of chaotic synchronization, which has poor performance in the presence of additive noise. This paper provides a thorough examination of all wireless radio frequency chaos-based communication systems. It begins by describing the difficulties of chaos implementations and synchronization processes, then moves on to a thorough literature review and study of chaos-based coherent techniques and their applications.
