Abstract

Rice (Oryza sativa L.) is an important food source consumed by more than half of the world's population. In Indonesia, rice plays a major role in providing food for the people. With a large population, Indonesia faces great challenges in meeting the food needs of its population. As the demand for rice increases every year, yield prediction is needed to plan plantings that can fulfill food needs. To improve rice yield through prediction, this process is done by considering various factors such as planting area (ha), urea, sp-36, za, npk, organic, npk formula, yield, and number of seeds. This research uses the CART method to build a web based application that helps the evaluation process. With CART, the data is divided into two parts, namely training data (100 samples) and test data (45 samples), with a division proportion of 70:30%. The implementation of this web application resulted in the classification of rice yields into two categories: low yield and high yield. The confusion matrix results of this classification show an accuracy value of 75%, recall 80%, precision 60%, and f1-score 68%. The CART algorithmproved to be good enough in predicting rice yields and worth using for classification.

Abstract

Mount Ciremai National Park (TNGC) is an important conservation area that is home to a variety of endemic flora and fauna. This study examines the effectiveness of environmental law implementation in protecting biodiversity in TNGC and identifies obstacles in law enforcement. Using normative legal methods with a legislative and conceptual approach, this study analyzes the implementation of Law Number 5 of 1990 and Law Number 32 of 2009 in the context of TNGC protection. The results of the study indicate that despite a strong legal framework, biodiversity protection in TNGC still faces serious challenges. Around 42.54% of the total area has been degraded, indicating the complete ineffectiveness of existing regulations. The main obstacles include minimal human resources, low public awareness and participation, lack of infrastructure, conflicts of interest between the government and local communities, and complicated bureaucracy. This study concludes that an approach involving various stakeholders is needed to improve the effectiveness of biodiversity protection in TNGC. Recommendations include increasing the capacity of law enforcement, public education, improving infrastructure, conflict resolution, and bureaucratic reform. The implementation of this strategy is expected to strengthen conservation efforts and ensure the sustainability of the TNGC ecosystem for future generations.

Abstract

The implementation of the Anti-Bribery Management System (SMAP) based on ISO 37001:2016 in the State Administrative Court (PTUN) is a strategic step by the Supreme Court of the Republic of Indonesia in building a clean, transparent, and integrity-based justice system. The implementation of SMAP has been carried out in a number of PTUNs, such as the Jakarta, Serang, and Manado PTUNs, through the establishment of the Anti-Bribery Compliance Unit (UKAP), the preparation of risk registers, internal training, and the provision of reporting mechanisms such as the Whistleblowing System (WBS) and the SIWAS application. Structural evaluations show compliance with ISO standards, but its substantive effectiveness still faces obstacles, including low reporting of violations, lack of employee understanding, and the lack of internalization of an anti-corruption culture as a whole. This study aims to analyze the regulation of SMAP in PTUN and evaluate its effectiveness as an instrument for preventing corruption in the administrative justice system. The research method used is normative juridical with a statute approach and conceptual approach, supported by literature studies. The results of the study show that the success of SMAP implementation is not only determined by administrative compliance, but also by the internalization of integrity values, the involvement of external audits, and strong leadership support. Therefore, strengthening an anti-bribery culture on an ongoing basis is a prerequisite for building an accountable and publicly trusted judiciary.
