This study aims to analyze junior high school students’ mathematical reasoning abilities in terms of their levels of learning independence. The research employed a descriptive qualitative approach involving three ninth-grade students from UPT SMP Negeri 5 Gresik, each representing high, medium, and low levels of learning independence. Data were collected through a self-regulated learning questionnaire, a mathematical reasoning test based on the topic of Systems of Linear Equations in Two Variables (SPLDV), and semi-structured interviews. Data analysis followed Miles and Huberman’s interactive model, consisting of data reduction, data display, and conclusion drawing. The results revealed that students with high learning independence demonstrated strong reasoning skills across all seven indicators of mathematical reasoning (representing statements, making conjectures, performing manipulations, constructing proofs, drawing conclusions, verifying arguments, and identifying patterns). Students with medium learning independence fulfilled only some indicators, while those with low learning independence could only make simple conjectures without systematic reasoning. These findings highlight that learning independence plays a crucial role in developing mathematical reasoning, as it enables students to regulate their thinking processes, evaluate solutions, and correct errors. Teachers are encouraged to integrate learning strategies that foster self-regulation—such as the CORE and Flipped Classroom models—to enhance students’ mathematical reasoning skills.

This study aims to describe students’ mathematical problem-solving abilities on the topic of Systems of Linear Equations in Two Variables (SPLDV) based on Polya’s problem-solving stages in relation to their levels of self-efficacy. The research employed a descriptive qualitative approach with three ninth-grade students from SMP Negeri 5 Gresik in the 2024/2025 academic year, selected through purposive sampling to represent high, medium, and low levels of self-efficacy. Data were collected using a self-efficacy questionnaire, problem-solving tests consisting of two contextual essay items on SPLDV, and semi-structured interviews. Data analysis followed the interactive model of Miles, Huberman, and Saldana, encompassing data reduction, display, and conclusion drawing, referring to Polya’s four stages: understanding the problem, devising a plan, carrying out the plan, and looking back. The results revealed that students with high self-efficacy were able to complete all four stages comprehensively and reflectively, demonstrating systematic and accurate reasoning. Students with medium self-efficacy successfully performed the first three stages but failed to verify their final results, while students with low self-efficacy only reached the stage of understanding the problem and struggled to plan or execute solutions. In conclusion, the level of self-efficacy influences students’ mathematical problem-solving performance, particularly in terms of strategic accuracy, procedural precision, and reflective evaluation.

This study aims to describe students’ mathematical critical thinking skills in terms of their learning styles based on the VARK model (Visual, Auditory, Reading/Writing, and Kinesthetic). The research employed a descriptive qualitative approach involving four seventh-grade students of SMP Negeri 9 Gresik, each representing one type of learning style. Data were collected through a learning style questionnaire, a mathematical critical thinking test based on Facione’s indicators, and in-depth interviews to strengthen the analysis. The results revealed that each learning style demonstrates distinct characteristics of critical thinking. Visual learners excelled in interpretation and self-regulation, auditory learners performed well in evaluation and verbal explanation, reading/writing learners showed strength in analysis and written reasoning, while kinesthetic learners were better in concrete activities but weaker in evaluation and inference. Overall, interpretation and analysis indicators were more dominant than evaluation and inference. These findings highlight the importance of implementing differentiated instruction aligned with students’ learning styles to foster optimal and comprehensive development of mathematical critical thinking skills.

This study aims to analyze the perceptions of teachers at Pondok Pesantren Assalafiyah Nurul Hidayah Pangkalpinang regarding Islamic banking. Despite the religious background of the teachers, the findings reveal that the majority still use conventional banks due to limited knowledge about Islamic banking principles, lack of socialization, and practical reasons such as convenience and proximity. The research uses a qualitative descriptive method involving 21 teachers through in-depth interviews, observations, and documentation. The results indicate that while the teachers have a generally positive view of Islamic banking, their understanding remains partial, particularly regarding profit-sharing mechanisms, riba prohibition, and Islamic financial products. Moreover, their interest in saving at Islamic banks is potential but requires further education and socialization to encourage real participation. This research highlights the need for more proactive promotion and financial literacy programs from Islamic banking institutions to increase public awareness, especially among religious educators, regarding the use of sharia-compliant financial services.

Study Interest State Administrative Law, Implementation of Business Licensing for Laundry Services Activities in Barong Tongkok District, West Kutai Regency, under the guidance of Dr. Siti Kotijah S.H., M.H and Agustina Wati S.H., M.H. Business licensing is an important aspect in the implementation of business activities, including laundry service businesses that are increasingly growing in urban communities. Laundry businesses require official permits from the local government as a form of compliance with regulations governing economic activities and environmental protection. With licensing, the government can supervise business activities and ensure that business actors comply with operational standards, including in the management of domestic waste generated from the washing process. Laundry business licensing is also an instrument to ensure consumer safety and comfort. Business permits include technical and administrative requirements, such as location permits, environmental permits (UKL-UPL/SPPL), and operational permits from related agencies such as the Investment and One-Stop Integrated Services Agency (DPMPTSP). Without complete permits, business actors can be subject to administrative sanctions to criminal penalties, as regulated in various laws and regulations such as Law Number 32 of 2009 concerning Environmental Protection and Management. Research on laundry business permits is important to provide a comprehensive picture of the processes, obstacles, and legal and environmental implications that may arise if business actors do not comply with applicable licensing provisions. Social legal research, with field studies at the Investment and One-Stop Integrated Service Office of West Kutai Regency, Barong Tongkok District and Laundry businesses in Barong Tongkok, West Kutai. Laundry businesses that have permits are 7, while there are still many laundry businesses that do not have laundry business permits. Business actors do not have business permits, because the reason is that their business is small, and the permit process is very difficult, and business actors avoid paying local taxes.

A country in its efforts to prosper the people requires a lot of money. For this reason, financial resources are needed to finance the state, which come from Customs levies and other legal levies. Smuggling crime is a serious problem in the administration of the state economy, this is because if smuggling increases with various physical, or administrative forms, it will result in more money not being collected by a country, thus hampering the targets set by the state through customs levies which are expected to increase every year. Legal smuggling is an act that aims to avoid the application of national law so that the person concerned obtains a certain benefit according to his wishes. This smuggling consists of two types, namely physical smuggling and administrative smuggling. Legislation regarding smuggling offenses is contained in Law Number 17 of 2006 concerning Amendments to Law of the Republic of Indonesia Number 10 of 1995 concerning Customs. And the parties responsible and related to the field of customs and excise must be more selective in checking export and import goods entering or leaving Indonesia, because misuse of procedures or authority will have a major impact on state losses.

This article discusses the importance of implementing Higher Order Thinking Skills (HOTS)-based learning evaluation in Islamic Religious Education (PAI) subjects. This topic is very crucial considering that PAI in the modern era is not sufficiently delivered through conventional methods such as memorization and lectures, but must encourage students to think critically, creatively, and reflectively towards religious teachings. The method used in this writing is a library research with a qualitative descriptive approach, reviewing relevant literature related to HOTS and its implementation in PAI learning evaluation. The results of the study indicate that HOTS-based evaluation is able to develop students' abilities in analyzing, evaluating, and creating solutions to contextual problems, thus supporting the formation of adaptive and highly reasoned religious characters. The implication is that the application of HOTS-based evaluation in PAI learning contributes significantly to students' cognitive development and is very relevant in the study of developmental psychology, especially in forming balanced intellectual and emotional intelligence.

This study aims to thoroughly examine the influence of menu variety, taste, and price on customers' purchasing decisions at CEZ-ROS Restaurant, located in Kediri Regency. Understanding these factors is crucial for the restaurant to enhance customer satisfaction and improve sales performance. The research employs a quantitative approach with an associative research type, designed to explore relationships between variables. The sampling technique used is accidental sampling, where respondents were selected based on convenience and their availability during the data collection period. This method allows for practical and efficient data gathering from actual restaurant customers. Data analysis involves several statistical tests to ensure accuracy and reliability. Initially, validity and reliability tests were conducted to confirm the suitability of the questionnaire. Then, multiple linear regression analysis was used to determine how menu variety, taste, and price individually and collectively influence purchasing decisions. Additionally, t-tests assessed the significance of each independent variable, while the F-test evaluated their simultaneous effect. The coefficient of determination (R²) provided insight into how much variation in purchasing decisions could be explained by these variables. The results indicate that menu variety, taste, and price significantly impact purchasing decisions both individually and together. Specifically, customers prefer restaurants offering a diverse menu, delicious food, and reasonable pricing. The F-test confirms the strong combined effect of these factors on consumer behavior. However, the coefficient of determination also suggests that while these variables are important, other external influences such as service quality, ambiance, and promotions may also affect purchasing decisions. Overall, this study highlights that CEZ-ROS Restaurant should focus on maintaining menu diversity, enhancing taste quality, and setting competitive prices to attract and retain customers effectively.

Therefore, the local culture-based mathematics e-module is proven valid, practical, and effective in enhancing students’ mathematical reasoning and learning motivation.

This study investigates the use of experimental statistical analysis as an instructional approach to enhance students’ understanding of variable relationships in science learning. Many students tend to memorize experimental results without comprehending the underlying relationships between variables, resulting in limited analytical reasoning and superficial understanding. To address this issue, the present study explores how integrating basic statistical tools-such as mean, correlation, and regression-into experimental activities can strengthen conceptual comprehension, analytical reasoning, and scientific literacy. Grounded in constructivist and inquiry-based learning frameworks, the research emphasizes active engagement, where students participate in data collection, analysis, and interpretation to draw evidence-based conclusions. The study employed a quasi-experimental design involving science students divided into experimental and control groups. Both groups conducted similar laboratory experiments, but only the experimental group received explicit instruction in statistical analysis. Data were collected through pre-tests and post-tests to measure changes in students’ understanding of variable relationships. The results indicated a 25% improvement in the experimental group’s comprehension and reasoning ability compared to the control group. Students who applied statistical analysis demonstrated greater proficiency in interpreting data, identifying causal patterns, and connecting theoretical knowledge to experimental findings. In contrast, students taught through traditional narrative-based instruction showed minimal gains and relied heavily on memorization. The findings highlight the effectiveness of integrating statistical reasoning in promoting critical thinking, problem-solving, and scientific reasoning skills.

This study aims to examine the impact of K-Pop celebrity worship on the psychological well-being of female adolescents in the Engene Medan Community. This quantitative research involved 60 respondents who are members of the community. Data were collected using a questionnaire and analyzed with SPSS 30 through validity and reliability tests, simple linear regression, t-test, F-test, and coefficient of determination (R²). The findings indicate that celebrity worship has a positive and significant effect on psychological well-being. The t-test produced a t-value (4.114) greater than the t-table (2.001) with a significance level of 0.001 < 0.05, while the F-test showed an F-value (16.921) exceeding the F-table (4.01) with the same significance level. The coefficient of determination (R²) of 0.226 shows that celebrity worship accounts for 22.6% of the variance in psychological well-being, while the remaining 77.4% is influenced by other factors not addressed in this study. This research concludes that involvement in celebrity worship activities, particularly at the entertainment-social level, can enhance positive feelings about oneself and improve overall psychological well-being. These findings reinforce the understanding that idolizing celebrities, as long as it remains within reasonable limits, can have a constructive impact on female adolescents.

This research examines judicial discrepancies in criminal cases of fiduciary transfer, focusing on Decision No. 45/Pid.Sus/2023/PN.SMN. Discrepancy is understood as the inconsistency between trial facts, the prosecutor’s evidence, and the judge’s considerations, which may lead to injustice and reduce public trust in the judiciary. The purpose of this study is to analyze the forms of discrepancy found in the decision and to assess their legal implications for the protection of the defendant’s rights and legal certainty. The research method employed is empirical juridical research with a sociological juridical approach, using statutory analysis, case studies, interviews with law enforcers, and literature review. The findings indicate disharmony in the assessment of intent (mens rea), the interpretation of written consent, and the proof of losses suffered by fiduciary recipients. Such discrepancies weaken the quality of the judgment, create legal uncertainty, and potentially violate the principle of fair trial. This study concludes that harmonization between trial facts, prosecutorial evidence, and judicial reasoning is necessary to maintain the integrity of the criminal justice system, improve the quality of judicial decisions, and strengthen legal protection for the parties involved.

The advancement of digital technology has created new opportunities for cybercrime, including revenge porn the non-consensual distribution of intimate content motivated by revenge. In Indonesia, such cases have surged significantly, predominantly affecting women of productive age, with multidimensional consequences including psychological trauma, social stigmatization, and job loss. This study analyzes the element 'without right' (tanpa hak) in Article 27 paragraph (1) of the Electronic Information and Transactions Law (UU ITE), which is both the core and the main source of legal uncertainty in prosecuting revenge porn cases. Through normative legal research using statute and case approaches, analyzing the Banten High Court Decision No. 96/Pid.Sus/2023/PT BTN, this research finds that the element 'without right' must be interpreted holistically by making a clear distinction between consent to create and consent to distribute. The appellate court decision demonstrates a progressive human rights-based approach, integrating the principle of reasonable expectation of privacy and victimological impacts. However, normative ambiguity continues to create disparities in rulings and disproportionate evidentiary burdens on victims. The research recommends legislative reform through amendment of the UU ITE or enactment of specific legislation on image-based sexual abuse to provide stronger legal certainty and substantive victim protection.

Islamic law faces significant challenges from the rapid advancements in bioethics and artificial intelligence (AI). The current responsive approach, based on ad-hoc fatwas, is deemed inadequate to address the systemic ethical dilemmas posed by these disruptive technologies. This research aims to propose a proactive and systematic ijtihad framework capable of anticipating and guiding technological innovation to align with the higher objectives of Shari'ah (Maqasid al-Shari'ah). Using a qualitative, library-based method with a juridical-normative and philosophical approach, this study analyzes primary and secondary Islamic legal sources through the Maqasid al-Shari'ah theoretical framework. The research finds the current model to be limited and, as a solution, offers a novelty in the form of the Hierarchical Model of Technological Ijtihad (HI-Tech). This model is a structured, interdisciplinary reasoning process, supported by a proposed institution, the Bio-Artificial Ijtihad Council (MIBA), and a digital platform, "Nur-Fatwa," for dissemination. The implication of these findings is the need for a paradigm shift for Islamic legal institutions towards an anticipatory, interdisciplinary, and institutionalized approach to address contemporary technological issues, thereby ensuring the continued relevance of Islamic law.

Literacy skills play an important  role in helping students clarify basic concepts, build relationships between concepts, reason and test each detail of each interrelated information and are able to derive each concept, thus students are accustomed to understanding each scientific process and activity carried out in Biology learning. The relationship between these two skills trains students to actively carry out in-depth scientific investigations.The purpose of this study was to identify the relationship between scientific literacy skills and scientific explanation skills in empowering scientific reasoning skills through the application of the Remap-NHT (Reading Concept Map-Numbered Head Together) learning model. This study included a quasi-experiment using a non-equivalent pretest-post-test control group design with a total sample of 85 eleventh grade students in the Natural Sciences department at SMAN 4 Malang in the 2023/2024 academic year. The population was distributed into 3 groups. Scientific literacy skills and scientific reasoning skills were assessed using an essay test, while scientific explanation skills were assessed using an assessment rubric. Data analysis was tested using multiple regression analysis. The results showed that (1) there was a significant relationship between scientific literacy skills and scientific reasoning skills; (2) there is a significant relationship between scientific explanation skills and scientific reasoning skills; and (3) there is a significant relationship between scientific literacy skills and scientific explanation skills that have an integral effect on scientific reasoning skills. The interrelationship between scientific literacy skills, scientific explanation skills and scientific reasoning skills can be observed in the regression equation Y = 0.317 * X1 + 0.995 * X2 + 30.113. Based on the findings, it is concluded that Remap-NHT is able to improve students' scientific literacy skills, scientific explanation skills, and scientific reasoning skills, the interrelationships of which influence each other.

This paper aims to explore the legal basis and ethical reasoning for the revocation of parental rights due to domestic violence by placing the child's best interests as a compass and mapping the gap between norms and judicial practices. The method used is normative-doctrinal legal research based on a literature review of the Domestic Violence Law, the Marriage Law, the Child Protection Law, selected jurisprudence, and scientific literature, analyzed qualitatively through systematic interpretation, argument construction, and linking to the facts of the impact of domestic violence on children. The results show that positive law provides a firm basis for sanctions and protections including restrictions on interaction and revocation of custody rights, but implementation is often hampered by vague evidence of psychological violence, the victim's economic dependence, and weak execution of alimony; revocation effectively breaks the cycle when accompanied by a protection order, a post-decision parenting plan, and ongoing psychosocial support. Policy implications include guidelines for proving coercive control, expanding access to timely protection orders, integrating trauma-informed services in religious courts, and a mechanism for executing alimony that does not burden victims, with schools, community health centers, and communities as early detection nodes. Ultimately, legal work and social networks converge in one simple goal: that home again means a safe place for children to return.
