Abstract

This article examines the rejection of a polygamous marriage legalization request at the West Jakarta Religious Court through Decision Number 1548/Pdt.G/2019/PA.JB, utilizing a critical legal studies perspective. The research is grounded in a multidimensional theoretical framework, incorporating elements of critical legal studies and statutory interpretation to scrutinize the judges’ legal interpretations. Methodologically, the study employs a rigorous approach, combining qualitative analysis of judicial decisions with theoretical insights from legal studies. The findings reveal the judges’ systematic interpretation of relevant legal provisions and highlight the tension between legal certainty, justice, and utility. The theoretical implications suggest a need for legal scholars and practitioners to reexamine prevailing paradigms and consider alternative frameworks that prioritize justice and social utility

Abstract

Stunting, or the condition of short stature in toddlers, is a problem caused by prolonged insufficient nutrition intake. This issue arises from inadequate feeding practices that do not meet the nutritional needs of a toddler. Stunting can begin during fetal development and becomes apparent around the age of two. Several factors contribute to stunting, including high-risk levels, lack of adequate housing, lack of proper sanitation facilities, lack of access to safe drinking water, and inadequate family income. This study employs k-medoids cluster analysis to identify the grouping of sub-districts in the Yogyakarta Special Region (DIY Province) based on stunting risk factors. The research findings indicate that Cluster 1 has the highest rates of stunting and lack of family income, Cluster 4 has the highest instances of inadequate access to safe drinking water and housing, and Cluster 5 has the highest rates of inadequate sanitation facilities.

Abstract

This study aims to classify potential customers’ characteristics based on non- performing loans through the random forest method. This research uses data obtained from Syariah Mandiri Bank branch in Jambi, which includes data on micro-financing customers in years 2016–2020. The random forest method is used for analysis. The novelty of this work is that, unlike existing researches that used other soft-computing methods, we employ Random Forest method, specifically using an imbalanced class sampling technique. The obtained results show that credit risk can be estimated by taking into account factors such as age, monthly installments, margin, price of insurance, loan principal, occupation, and long installments. The research results indicate that the sensitivity, precision, and G-mean value increase compared to using the original data. Random forest with oversampling technique has the high Area Under the ROC Curve score that is equal to 66.69%.

Abstract

Blood cells that flow in the human body provide information to diagnose a disease. The information provided can be obtained through images of these blood cells using image processing techniques. Malaria is a very deadly disease and can affect everyone. Patients with malaria will experience anaemia because the red blood cells or erythrocytes are contaminated with plasmodium. This study offers an alternative solution to malaria disease identification through the image classification of red blood cells, by applying image processing and image classification methods with XGBoost and random forest. The research was conducted using the R programming language in RStudio and Python. The accuracy of XGBoost and random forest methods were 71.26% and 77.58%, respectively. Therefore, the random forest provided a better optimal classification model with higher accuracy. The model is used to build an application which is R web-based, RShiny. In practice, this application can be used by health workers in classifying patients based on red blood cell images such that the health centre would be easier to manage the existing patients.

Abstract

This study forecasted inflation in Indonesia using the Recurrent Neural Network Long Short-Term Memory (RNN-LSTM) model, ideal for nonlinear, complex time series data. It evaluated the effects of different activation functions, such as Logistic, Gompertz, and Hyperbolic Tangent (tanh); and weight update methods, such as Stochastic Gradient Descent (SGD) and Adaptive Gradient (AdaGrad) on RNN-LSTM performance. Monthly inflation data from January 2005 to December 2023 underwent preprocessing, including normalization and autoregressive lag-based input selection. Model accuracy was assessed with Root Mean Squared Error (RMSE) and Symmetric Mean Absolute Percentage Error (SMAPE). The findings indicated that the RNN-LSTM model with the logistic activation function and SGD optimization achieved the highest accuracy, outperforming traditional models such as Exponential Smoothing (ETS), Autoregressive Integrated Moving Average (ARIMA), Feedforward Neural Network (FFNN), and Recurrent Neural Network (RNN). Additionally, optimal learning rate and epoch values were identified, enhancing model stability and precision. In conclusion, the study confirms that the RNN-LSTM model is effective for inflation forecasting when optimized with specific activation functions and optimization methods. It recommends further exploration of neuron configurations and alternative models, such as the Gated Recurrent Unit (GRU), to improve forecast accuracy.

Abstract

After attendance, the enactment of the Supreme Court Circular (SEMA) Number 3 of 2018 answers the legal vacuum over isbat for Polygamous marriage. But in practice, the SEMA confuses its implementation. This study aims to analyze the application of polygamous marriage law in SEMA number 3 of 2018 and the juridical implications for justice, expediency, and legal certainty. This research includes normative legal research with statutory and conceptual approaches. Gustav Radbruch's theory of legal purpose is used as his analysis knife. The study concluded that closing the door of Isbat for Polygamous marriage is not the right solution because marriage isbat is one way to obtain legal guarantees in the eyes of the state. The aggrieved subject of the SEMA was a polygamous wife who could not take legal action in seeking justice. Judging from Gustav Radbruch's theory, SEMA number 3 of 2018 has not met the elements of legal objectives. The provisions in SEMA number 3 of 2018 only accommodate the interests of children. The rights of polygamous wives should be prioritized because the benefits received are more significant than tightly closing the door of isbat for Polygamous marriage. It is necessary to review SEMA number 3 of 2018 to contain concrete values of justice, expediency and legal certainty for children and wives.

Abstract

East Java Province is geographically close to the Eurasian and Indo-Australian Plate subduction zones, resulting in frequent earthquakes East Java Province has a high population density, so it is very risky if disaster occurs. One preventive solution to reduce this impact is estimating damage when an earthquake occurs. The purpose of this study was to determine the best modeling of damages due to earthquakes in East Java Province, using the amount of house damage as a response variable, while depth of the epicenter and the strength of the earthquake as predictor variables. It is suspected that there is a spatial dependency effect in this case, so the solution is to use regression with an area approach, namely the Spatial Durbin Model (SDM). The amount of house damage is collected from BNPB, the epicenter and the magnitude of earthquake collected from BMKG in 2021. The result shows that SDM is good at explaining the dependency relationship between response and predictor variables. The significant predictor variables are the depth of epicenter and the strength of the earthquake. It is meaning that the magnitude and the depth of the epicenter of the earthquake in an area have an impact on other adjacent areas. There is a relationship between the amount of house damage in one area and other adjacent areas. The Regency will have a high number of damaged houses if it is adjacent to a Regency that has a high number of damaged houses
