The rapid development of financial technology (fintech) and crypto assets has created a paradox in the global financial system: while promoting inclusion and efficiency, it also opens new vulnerabilities for money laundering offenses. Notaries, as public officials and legal professionals involved in various financial and business transactions, are at the forefront of preventing this misuse. This article analyzes the specific risks of money laundering through fintech and crypto assets and formulates the due diligence framework required by notaries in carrying out their preventive functions. The research method uses a normative juridical approach with doctrinal analysis of regulations and international standards, enriched with case studies and best practice references. The findings indicate that notaries face three main challenges: (1) difficulty in identifying parties in virtual transactions, (2) the volatility and relative anonymity of crypto assets, and (3) the gap between the speed of technological innovation and regulatory adaptation. This article proposes an Enhanced Digital Due Diligence (ED3) model that integrates digital verification technology, blockchain forensic analysis, and a dynamic risk-based approach. This framework is expected to strengthen the role of notaries as gatekeepers in the rapidly evolving digital financial ecosystem while maintaining the profession's relevance in the era of digital transformation.

The diversity of social media used by teenagers today can influence Fear of Missing Out (FoMO) behavior, a condition where someone feels left out of information, trends, or activities carried out by others. This condition is characterized by fear, anxiety, difficulty controlling the desire to stay connected, and a tendency to compare oneself with others on social media. Teenagers are the group most vulnerable to FoMO due to their high intensity of social media use and their still-developing social needs. This reseach seeks to examine the association between scial media diversity and FoMO behavior among eleventh-grade student at SMAN 4 Tuban. The study employed a quantitative analytic design using a cross-sectional approach. The research population consists of all 11th grade students, totaling 157 respondents, selected using simple random sampling. The instruments used are a social media diversity questionnaire and a FoMO behavior questionnaire. Data analysis uses the Chi-Square test with a significance level of α = 0.05. The results of the study show a p-value of 0.000, which means p < 0.05, so H1 is accepted. This shows that there is a significant relationship between social media diversity and FoMO behavior in adolescents. The more diverse the social media platforms used, the higher the tendency for adolescents to experience FoMO. Based on these results, it can be concluded that social media diversity influences FoMO behavior among 11th grade students at SMAN 4 Tuban.

The main focus of this study was to ensure that the evaluation tools used were truly capable of describing students' competency achievements. Data analysis was conducted through observation results and student responses on Google Forms, which were then processed using the Anates Version 4.0 application. The results of the analysis showed that most of the questions had high validity and reliability, good discrimination power, and a moderate level of difficulty. However, the overall quality of the distractors was not good enough, and there were no questions in the difficult category. Overall, the quality of the questions in this subject can be categorized as good and suitable for evaluating the learning of vocational high school students in grades XI and XII.

Mathematics is a core subject that develops critical thinking skills; however, many third to fifth-grade elementary school students face difficulties with conventional teaching methods that tend to be uniform and less adaptive. This study aims to develop and implement a mobile-based educational game, "Ethno Run," which integrates the Bayesian Knowledge Tracing (BKT) algorithm to provide an adaptive learning experience. The method used is Research and Development (R&D) with the Multimedia Development Life Cycle (MDLC) framework. The system uses BKT to track students' mastery in real-time by analyzing their responses to pre-tests and exercises within the game, which then adjusts the difficulty level and focuses the post-test on areas identified as weak, such as arithmetic operations and geometry. The findings show that this adaptive approach significantly improves learning outcomes, with the average score increasing from 44.33 on the pre-test to 85.33 on the post-test among 30 students. This study concludes that the integration of Artificial Intelligence through BKT effectively personalizes learning, enhances student motivation, and provides data-driven insights for teachers regarding students' progress. The implication of this research is that adaptive game-based learning serves as a feasible interactive solution to bridge the gap in conventional basic mathematics education.

Loss and grief are psychological experiences that significantly affect an individual’s mental state. This process involves various emotional, cognitive, and behavioral changes that can affect a person’s well-being in the long term. This study aims to describe the emotional, cognitive, and behavioral affects that arise in individuals after experiencing loss, as well as the factors that strengthen or weaken their responses to the grieving process. The method used in this study is qualitative, with a literature review approach from various relevant clinical psychology and mental health studies. The results indicate that individuals who experience loss are vulnerable to increased emotional stress, anxiety, depression, and significant declines in social functioning. Furthermore, this article highlights that the quality of social support received, the way individuals make meaning of the loss, and the coping mechanisms they choose play a crucial role in determining the level of grief response. These factors can either accelerate or delay the healing process. An unresolved grieving process or one that is handled in an unhealthy manner can develop into more serious psychological disorders, such as Prolonged Grief Disorder (PGD). PGD is a condition characterized by difficulty in accepting the loss, which can persist for months or even years. This article emphasizes that loss is not merely an emotional disturbance but also a complex psychological process. This process requires a deep understanding, strong social support, and appropriate interventions to maintain an individual’s mental health and help them recover more effectively.

The quality of assessment instruments plays an important role in determining the accuracy of measuring student learning outcomes in science learning in elementary schools. A good test instrument must meet certain criteria, such as validity, reliability, difficulty level, and discrimination power. This study aims to analyze the quality of daily science test items in grade VIc elementary schools based on these four criteria. The study used a quantitative. The subjects were 19 sixth-grade students, while the instrument analyzed consisted of 25 multiple-choice questions. Data processing and analysis were carried out using Microsoft Excel to calculate item validity through item correlation with total score, test reliability using internal consistency, difficulty level index, and discrimination index. The analysis results showed that 17 questions (68%) were declared valid, while 8 questions (32%) were invalid and needed to be improved. The results of the reliability test indicated that the test instrument had good reliability and was suitable for use as a measuring tool for student learning outcomes. Judging from the level of difficulty, 20 questions (80%) were moderate and 5 questions (20%) were easy, indicating a relatively balanced level of difficulty. Based on the discrimination power, 16 questions (66%) had very good discrimination power, 4 questions (16%) were good, 4 questions (16%) were sufficient, and 1 question (4%) was poor. Based on these findings, it can be concluded that the quality of the sixth grade science daily test questions is classified as good and the test instrument is suitable for use, but improvements are still needed on invalid questions and those with low discrimination power so that the quality of the assessment is more optimal. This study emphasizes the importance of teachers' abilities in compiling and analyzing test items to ensure that the assessment of science learning is objective, valid, and reliable.

Data security is a critical aspect in the digital era due to the increasing exchange of sensitive information through electronic media. One widely used approach to protect data confidentiality is cryptography, particularly asymmetric encryption algorithms. This study aims to analyze the implementation of the Rivest–Shamir–Adleman (RSA) algorithm as a data security mechanism through an encryption and decryption process. The research method used is an experimental approach by implementing the RSA algorithm in a text-based data security simulation. The stages include key generation, encryption, and decryption processes, followed by analysis of the correctness and effectiveness of the algorithm in maintaining data confidentiality. The results show that the RSA algorithm is capable of converting plaintext into unreadable ciphertext and successfully restoring it to its original form through the decryption process using the correct private key. This confirms that RSA provides a high level of security based on the difficulty of factoring large prime numbers. The implication of this study is that the RSA algorithm can be effectively applied to secure sensitive data transmission in information systems, especially in environments requiring strong authentication and confidentiality.

This research aims to analyze the application of material criminal law against perpetrators of sexual abuse crimes against children and examine the judge's considerations in sentencing in cases of sexual abuse against children committed by teachers. The study focuses on Court Decision Number 1649/Pid.Sus/2020/PN.Mks, where a Quran teacher was convicted of committing sexual abuse against several of his students. This normative legal research employs statutory and case approaches, analyzing primary legal materials including the Criminal Code (KUHP), Law Number 35 of 2014 concerning Child Protection, and the aforementioned court decision. The findings indicate that the application of material criminal law in this case has been in accordance with Article 82 paragraph (1), jo Article 76E of the Child Protection Law, where all elements of the crime were proven fulfilled. However, the judge's consideration in sentencing raises critical concerns regarding the application of aggravating factors. Under Article 82 paragraph (4) of the Child Protection Law, when sexual abuse is committed by educators, the punishment should be increased by one-third. The court sentenced the defendant to 6 years and 6 months imprisonment and a fine of Rp. 60,000,000, whereas according to the applicable law with aggravating factors, the sentence should have been 8 years and 8 months imprisonment. The study also identifies obstacles in handling such cases, including children's difficulty in revealing traumatic events, victims' fear and shame, limited witnesses, threats from perpetrators, and inadequate resources. The research recommends consistent application of sentence enhancement for perpetrators who are educators, improved inter-agency cooperation in handling child victims, enhanced school security measures, and comprehensive legal protection for child victims throughout the judicial process.
