Abstract

Traffic accident is one of the highest causes of death in Indonesia following coronary disease and tuberculosis. Traffic accident is classified into three: mild, moderate and severe. The aim of this research was to determine the significant factors causing traffic accidents in Cilacap Regency using multinomial logistic regression. The data used were secondary data from the Resort Police of Cilacap Regency. The research’s response variable was accident classification deemed as a nominal scale, while the predictor variables were day of occurrence, time of occurrence, accident type, accident location, situation, weather problem, number of vehicles involved, and number of victims of nominal, ordinal and ratio scales. The research results show that the accident type, accident location, situation, and number of victim variables significantly influence the three accident classifications.

Abstract

Cilacap is the largest regency located in the southwest of Central Java Province. The rain fall in Cilacap has seasonal variation for monthly period, thus information on rainfall is very important for the Government of Cilacap Regency its people, especially farmers. The usefulness of forecasting method in predicting the volume of rainfall is important. It motivates development of a system that can predict future amount of rainfall. A fluctuation analysis on forecasting result can be used for local government’s policy making purpose. This paper analyses and presents SARIMA method to develop a forecasting model which may support and predict rainfall volume. The dataset for model development was collected from time series data published by Meteorology, Climatology and Geophysics Agency Tunggul Wulung Station from January 2009 to December 2022. The data were divided into data training (to December 2021) and data testing (January to December 2022) groups. The use of data training produced SARIMA model (2,0,2)(0,0,1)12 as the selected model. The model achieved 0.70% for MAPE using data testing. It indicated the final model’s capability to closely represent and made prediction based on the rainfall history dataset. The model produced was used to forecast the rainfall from January 2023 to December 2024. The forecast results were analyzed in relation to agricultural insurance program.

Abstract

This research discusses the formation of the Fractional Logistic model and its solution analysis, as well as its simulation to predict the Human Development Index in Cilacap Regency using the Fractional Logistic growth model. This study uses secondary data obtained from the official website of the Central Statistics Agency of Cilacap Regency. Based on these data, the growth of the Human Development Index in Cilacap Regency has increased relatively. This shows the Cilacap community's good quality of life. Based on the environmental carrying capacity value of 73, a relative growth rate per year of 0.14273269 is obtained. This model predicts the Human Development Index in Cilacap Regency in 2024 and 2025. The prediction results for 2024 of 71.47 and 2025 of 71.67 are achieved when the fractional derivative order is one. The best approximate solution is obtained when the fractional derivative order is 1, 0.95 0.90, 0.85, 0.80 and 0.75.

Abstract

The pu IDR ose of this research is to solve the 0/1 integer knapsack problem, which is a problem of selecting items from a number of available items where each item has different weights and profits. The delivery of items at J&T Cargo Purwokerto is one of many item selection problems. The delivery of items at J&T Cargo Purwokerto is carried out progressively with higher profit values ​​first, due to the delivery capacity being able to accommodate only 700 kg. In order for J&T Cargo Purwokerto to obtain maximum profit, item selection for delivery must be carried out first. The item selection at J&T Cargo Purwokerto can be solved using the 0/1 integer knapsack problem method with a forward recursive dynamic programming algorithm with the help of Matlab R2021A software. The results of the research indicate that on July 1, 2025, a maximum profit of IDR 3,038,850 was achieved with a weight of 700 kg. On 2nd July 2025, a maximum profit of IDR 4,884,985 was achieved with a weight of 700 kg. On 3rd July 2025, a maximum profit of IDR 7,732,155 was achieved with a weight of 699 kg.

Abstract

This paper will discuss the solution of the fractional Black-Scholes equation which is a general form of the Black-Scholes equation and the novelty of research on the modified Black-Scholes equation. The methods for finding solutions to the fractional Black Scholes equation have been written in many international journals. The solution to the fractional Black Scholes equation in this case is reviewed by the Fractional Calculus approach. With the Fractional Calculus approach, the solution process in finding solutions to the Fractional Black Scholes equation becomes more efficient. Some of the methods used to find solutions to the Fractional Black Scholes Equation include the Sumudu transformation method, the series expansion method, the Homotopy perturbation method, the Adomian decomposition method, and the Laplace Adomian decomposition method.

Abstract

A Catalan number is a positive number obtained by calculating the combined structure of a sequence. Catalan numbers have a general form and a recursive form that can be identified through Diagonal-Avoiding Paths and Balanced Parentheses. Catalan numbers have congruence on the modulo of integers. One of them is on the prime number modulo p. For every odd prime p, p does not divisible by  and the product of all numbers d by d between 0 and  and the Greatest Common Divisor of d and p is 1, will be congruent to -1 modulo . For every integer a with a between 0 and  , the Catalan numbers have different values ​​on modulo   and is congruent to  and so on until  modulo . For a between (p+1) to p , the catalan numbers  have different values ​​on modulo and  is congruent to   and so on until  modulo .

Abstract

Aplikasi Model Pertumbuhan Logistik dalam Menentukan Proyeksi Penduduk di Kabupaten Banyumas. Kabupaten Banyumas adalah salah satu kabupaten di Jawa Tengah yang memiliki kepadatan penduduk terbanyak ketiga dengan luas wilayah seluas 1.328 km². Berdasarkan data dari BPS jumlah penduduk di Kabupaten Banyumas setiap tahunnya semakin bertambah, maka diperlukan solusi untuk mengurangi dampak negatif agar tidak terjadi adanya ledakan populasi. Solusi yang dapat digunakan untuk memproyeksi penduduk di Kabupaten Banyumas yaitu dengan menggunakan model pertumbuhan logistik. Model ini digunakan untuk menghitung nilai laju pertumbuhan dan daya dukung lingkungan (carrying capacity) dengan menggunakan data jumlah penduduk di Kabupaten Banyumas tahun 2015 sampai tahun 2021. Hasil yang diperoleh menunjukan bahwa daya dukung lingkungan (carrying capacity) yang membatasi penduduk di Kabupaten Banyumas adalah  dengan laju pertumbuhan relatif pertahunnya sebesar 7,75%. Model ini juga memproyeksikan jumlah penduduk di Kabupaten Banyumas dari tahun 2022 sampai tahun 2030. Dengan perhitungan menggunakan Microsoft Excel diperoleh proyeksi jumlah penduduk di Kabupaten Banyumas pada tahun 2022 berjumlah 1.811.059 jiwa hingga tahun 2030 diperkirakan berjumlah 1.944.653 jiwa.

Abstract

National development is an effort to improve economic performance in order to be able to create jobs and get a decent life for all people. One of the goals of national development is to reduce poverty. This study aims to determine the effect of education and unemployment on poverty from 2016-2020. Education is taken from data on the Mean Years School and unemployment is taken from data on the open unemployment rate. The type of data used is secondary data. The method used in this research is multiple linear regression with the Mean Years School and the open unemployment rate as the independent variables and the number of poor people as the dependent variable. The results of the linear regression analysis with two independent variables show that the coefficient of determination is 97.9%, meaning that the Mean Years School and the Open Unemployment Rate variable have an effect on poverty of 97.9%. Simultaneously, using the F statistical test, it is proven that the independent variables simultaneously affect poverty in Banyumas Regency with a significance level value (α) = 0.05. Meanwhile partially, by using the t statistic test, it is proven that the independent variable has a partial effect on poverty in Banyumas Regency.
