Abstract

Mathematical modeling in the world of economics and banking has particular relevance, especially in terms of providing capital for business activities, particularly for Micro, Small, and Medium Enterprises (MSMEs). Currently, banking activities are predominantly dominated by conventional banks that apply interest, which in Islamic Sharia is considered as riba, and it is incumbent upon Muslims to avoid riba and conduct all their affairs in accordance with Islamic Sharia. This research discusses a mathematical model of a profit-loss sharing system in accordance with Islamic Sharia using the profit-loss sharing model scheme, which is one of the investment models in Islamic finance with a musyarakah contract. The data is derived from the daily profit and loss of a micro trader for the period of September 2023 in Cijantung, East Jakarta, which is then generated for periods of 35, 40, and 50 days, following normal, lognormal, and gamma distributions, with an investment capital of Rp 1,500,000, Rp 3,000,000, and Rp 4,500,000, and profit-sharing portions of 2%, 5%, and 7%. This research is capable of demonstrating a profit-sharing scheme and optimization functions in profit distribution, as well as determining parameters that are more advantageous for traders and capital owners compared to the usury model because the imposed penalties are considered burdensome for the public. Generating data following a normal distribution provides a more realistic profit-sharing scheme but a lognormal and gamma distribution yields the largest profit-sharing portion for investor and trader.

Abstract

Carbon dioxide (CO₂) emissions are one of the primary causes of climate change, which has a significant impact on the environment and human health. As the second-largest emitter of carbon dioxide after China, the United States requires an effective forecasting system to monitor and control these emissions. This study aims to develop a time series model with independent variables using a combined SARIMA-QR method and compare its accuracy with the SARIMA model. The independent variables used include total industrial energy consumption, total electricity consumption, and the forecast values from the SARIMA model. The comparison of model accuracy is based on the MAPE values from the testing data between the SARIMA model and the SARIMA-QR model at the 0.50 quantile. The analysis results show that the SARIMA model achieves a MAPE value of 5.78%, while the SARIMA-QR model at the 0.50 quantile has a lower MAPE value compared to the SARIMA model. The improvement in accuracy in the SARIMA-QR model is due to the integration of independent variables, which provide additional relevant information, such as total industrial and electricity consumption, as well as the forecast values from the SARIMA model. This demonstrates that the use of independent variables can improve the accuracy of CO₂ emission predictions. The comparison of the accuracy of these two models is expected to serve as an important reference for the United States government in formulating more effective policies to manage carbon dioxide emissions more optimally.

Abstract

Waste is a global problem that must be resolved so that the environment is well maintained, especially in developing countries such as Indonesia. A good understanding of waste will have an impact on optimal waste management. Waste banks are one way out in waste management so that what was originally useless becomes marketable. In its implementation, the waste bank must have data collection and transparency of customer waste data in real time. Technology is one of the main solutions to produce digital products that make it easier for people to access information accurately. By using the Convolutional Neural Network (CNN) algorithm, an image of image data can be predicted with good accuracy. Along with the development of technology today, various kinds of architectures are present, one of which is Mobilenet. This architecture has the ability to run machine learning models on mobile and IoT devices. Furthermore, the resulting model is quite good with an accuracy rate of 96% on Metal waste, 92% on Paper and Organic waste, 80% on Cardboard waste, 76% on Glass waste, and 72% on Plastic waste. The disadvantages that exist in this model when predicting with almost similar shapes and images that have many objects in them, the error will be greater so there is a possibility of error in predicting the results of the garbage image.

Abstract

This study develops mathematical model for the spread of HIV/AIDS by the population is divided into seven sub-populations, namely the susceptible unaware HIV subpopulation, the susceptible aware HIV sub-population, the infected sub-population, the pre-AIDS sub-population, the ARV treatment sub-population, the AIDS sub-population, and unlikely to be infected with HIV/AIDS sub-population. In this mathematical model, two equilibrium points are obtained, namely the disease-free equilibrium point and the disease-endemic equilibrium point and the basic reproduction number . The stability analysis shows that the disease-free equilibrium point is locally asymptotically stable if  and the disease-endemic equilibrium point is locally asymptotically stable if . Numerical simulations of the equilibrium points are carried out to provide an overview of the analyzed results with parameter values from several sources. Based on the sensitivity analysis, the parameters that significantly affect the spread of HIV/AIDS are the contact rate of HIV-unaware individuals with infected individuals and the transmission rate of HIV infection

Abstract

The classic assumptions used to calculate fractional ages in valuing insurance premiums with payouts made immediately after death result in discontinuous probabilities of immediate death at integer ages because the assumption only applies to a 1-year time interval, specifically . The new assumption, namely the quadratic fractional age assumption, has successfully introduced continuity at integer ages. This study discusses the conditions for applying the quadratic fractional age assumption and its influence on the calculation of semi-continuous dual-purpose insurance premiums, where the policyholder's beneficiaries receive the sum assured if the insured individual passes away before the contract ends or receive protection if the policyholder survives until the end of the contract, with premium payments made on a monthly basis. Simulation results indicate that not all mortality tables meet the requirements for the quadratic fractional age assumption, where the value falls between . Only the Commissioners Standard Ordinary Table 1958 meets this criterion. Monthly premiums calculated using the quadratic fractional age assumption yield smaller values compared to premiums calculated using the constant force of mortality assumption and the uniform distribution of death assumption.

Abstract

Maize is a strategic commodity with growing demand; however, domestic productivity faces challenges due to the limited availability of high-quality seeds, fertilizers, and other production inputs. Analyzing production risk in maize farming is essential for identifying factors contributing to yield uncertainty. This study examines the factors influencing maize production risk in dryland farming in Karanganyar Regency using a multiple linear regression model with the heteroscedasticity approach by Just and Pope, based on a sample of 60 farmers. The results indicate that the production risk of maize in Karanganyar's dryland areas, as reflected by a coefficient of variation of 24.08%, is relatively low. Production risk is significantly influenced by fertilizer application and labor input. Phonska, SP-36, and urea fertilizers have a notable impact that helps mitigate production risk. Additionally, labor input is crucial in determining crop yields, with greater labor availability correlating with lower production risk for farmers. In contrast, maize seeds, land area, organic fertilizers, and pesticides insignificantly affect production risk. These findings highlight the importance of effective agricultural input management, particularly the selection of appropriate fertilizers and labor optimization, in reducing uncertainty in maize production.

Abstract

Maize is the main raw material for animal feed, and weakening maize prices have a significant impact on the prices of livestock products such as chicken and eggs. The high demand for animal feed can drive up maize prices. Keywords: Volatility, Integration, Market, Maize Price. This condition is further exacerbated during the COVID-19 pandemic, disruptions to the global supply chain, distribution regulations, and economic instability have caused maize price volatility to increase sharply. The purpose of this study is to analyze maize price volatility and market integration at the producer, consumer and world levels. This study uses secondary data obtained from the Central Statistics Agency (BPS), Ministry of Trade, Ministry of Agriculture, Food Prices and the World Bank. The data analysis used is the coefficient of variation and Vector Error Correction Model (VECM). The results show that maize price volatility at the producer and consumer levels is relatively low, while at the world level it is high. The results of the integration analysis obtained prices at the producer, consumer, and world levels have long-term integration. Only consumer maize prices (HJK) significantly adjust in the short term to long-term sufficiency. Maize prices at the consumer level are greatly influenced by producer prices, which indicates that vertical price transmission from producers to consumers is quite strong. The influence of world prices exists, but is relatively small and indirect. Production costs, input availability, and market channels are the main factors in determining maize prices at the producer level. Efficient marketing channels can result in better price realization for farmers so that farmers get better profits. The government must be able to maintain a good farming climate for farmers
