The proliferation of online gambling promotional comments on Indonesian social media has become a serious issue requiring fast and accurate automated handling. This study aims to implement a Hybrid Recurrent Neural Network (RNN) and Long Short-Term Memory (LSTM) method to classify online gambling comments and compare its performance with standalone RNN and LSTM models. The research utilized a dataset of 10,230 comments subjected to comprehensive preprocessing stages, including the normalization of non-standard language using a slang dictionary. Testing was conducted across three data-splitting scenarios: 90:10, 80:20, and 70:30. Experimental results demonstrate that the standalone LSTM model achieved the highest average accuracy of 97.45%. However, the Hybrid RNN–LSTM model showed significant superiority in terms of performance stability, yielding the lowest standard deviation (0.0027) and the smallest Coefficient of Variation (0.28%) across all scenarios. These findings indicate that while the LSTM architecture is highly effective at capturing short-text context, the Hybrid approach provides better robustness against fluctuations in data proportions, making it highly relevant for implementation as an automated detection system on social media.

The development of information technology has become a primary pillar in enhancing corporate operational efficiency, where rapid and accurate data integration significantly determines business competitiveness. Case study in PT Gawi Anjung Bersama (GAB) revealed that the company is facing operational constraints because the management of delivery orders and invoices still relies on conventional office applications such as Microsoft Excel and Word. This procedure causes hurdles in data sharing among staff and results in low information security due to the absence of integrated access control settings. This research aims to design and develop the Gawi Anjung Bersama Information System (SIGAB), a web-based system implementing the CodeIgniter framework. The system is developed using Waterfall model, encompassing stages from analysis, design, and implementation to testing. The research flow starts with problem identification, primary and secondary data collection, and functional and non-functional requirements analysis. The system is designed using Unified Modeling Language (UML) modeling, specifically Use Case and Class Diagrams, as well as Entity Relationship Diagrams (ERD) for the database. The system interface is designed as wireframes on Figma web. This system separates access rights into three main actors namely owner, administrator, and staff, to ensure data security. Blackbox testing results, conducted after the system was hosted, indicate that all functional features operate as intended. The implementation of SIGAB is expected to optimize the management of delivery orders and invoices at PT GAB.

This research is prompted by legal complications within civil procedural law, specifically regarding the failure of judges to identify formal defects in special powers of attorney during the preliminary stages of trial. The central focus of this study examines Decision Number 14/Pdt.G/2025/PN Kba, in which a lawsuit was declared inadmissible (Niet Ontvankelijke Verklaard) only after a seven-month litigation process that had already progressed through evidentiary hearings and local inspections. The objective is to evaluate the effectiveness of the dominus litis principle in empowering judges to provide procedural guidance for lawsuit amendments, while testing its alignment with the principles of simple, fast, and low-cost justice. Employing a normative legal research method with statutory and case-based approaches, the legal materials are analyzed qualitatively using the legal syllogism technique. The findings indicate that the application of the dominus litis principle in the a quo case remains ineffective due to the judges' passive and formalistic tendencies. Such an approach neglects the ex-officio authority mandated under Articles 119 and 132 of the HIR. This ineffectiveness results in significant judicial inefficiency, causing undue loss of time and financial resources for justice seekers. Consequently, this study recommends strengthening rigorous initial screening mechanisms by the panel of judges at the first hearing. This preventive measure is essential to curb the waste of judicial resources and ensure the realization of substantial justice for all disputing parties.

This study aims to analyze and obtain empirical evidence regarding the effect of profitability, leverage, and sales growth on tax avoidance in energy sector companies listed on the Indonesia Stock Exchange (IDX) for the 2020–2024 period. This research method uses a quantitative approach with secondary data in the form of annual financial reports obtained from the official IDX website and related company websites. The sampling technique used a purposive sampling method to obtain a sample of companies that met the research criteria during the observation period. The dependent variable in this study is tax avoidance, which is proxied by the Effective Tax Rate (ETR), while the independent variables consist of profitability as measured by Return on Assets (ROA), leverage as measured by the Debt to Equity Ratio (DER), and sales growth as measured by annual sales growth. The data analysis technique uses panel data regression through the stages of selecting the best model, classical assumption testing, multiple linear regression analysis, and hypothesis testing. The results of the study indicate that profitability, leverage, and sales growth simultaneously influence tax avoidance. Partially, profitability influences tax avoidance, while leverage and sales growth do not.

Multicollinearity is one of the common issues in multiple linear regression that can lead to instability in the estimation of regression coefficients. This study aims to examine the impact of multicollinearity on regression models and to evaluate the use of Ridge Regression as an alternative estimation method. The study employs simulated data consisting of 1,000 observations, including one dependent variable and four independent variables designed to exhibit high correlation. The analysis begins with model estimation using the Ordinary Least Squares (OLS) method, followed by multicollinearity testing using the Variance Inflation Factor (VIF). The OLS results indicate that most independent variables significantly influence the dependent variable, with a coefficient of determination (R²) of 0.9863. However, the high VIF values reveal the presence of strong multicollinearity in the model. To address this issue, Ridge Regression is applied, with the optimal penalty parameter determined through cross-validation, yielding a lambda value of 4.201589. The results show that the regression coefficients in the Ridge model undergo shrinkage, resulting in greater stability compared to the OLS estimates. Model evaluation indicates that the Mean Squared Error (MSE) for the OLS model is 24.77, whereas the Ridge model produces an MSE of 29.72. Although the Ridge model exhibits a slightly higher MSE, it effectively mitigates the impact of multicollinearity and provides more stable parameter estimates.

Vaname shrimp (Litopenaeus Vannamei) is one of Indonesia's fishery commodities with high economic value. Vaname shrimp production in Indonesia continues to increase. However, obstacles sometimes arise in cultivation activities, such as the emergence of shrimp diseases and poor water quality. High stocking density and shrimp feeding can cause a decline in water quality. In addition, pond water quality is influenced by pond location and the surrounding environment, such as agriculture, settlements, mangroves, and the sea. This causes ponds to have different water qualities. One of the diseases that often attacks shrimp farming is caused by the bacterium Vibrio sp. The abundance of Vibrio sp. bacteria is closely related to pond water quality and the environmental conditions around the pond. The methods used were TPC testing and multiple linear regression testing. Based on the results of the study, the abundance of Vibrio sp. bacteria in pond A was the highest at 8.3 x 102, and pond C had the lowest at 3.1 x 102. Water quality testing in three different ponds showed safe limits for cultivation, except for nitrite testing. Based on the simple linear regression test, the water quality parameters that significantly affect the abundance of Vibrio sp. bacteria are pH, temperature, and nitrite.
