 Education in vocational high schools (SMKs) requires effective data management to improve students’ academic achievement and discipline. At SMK Islam Secang, students’ academic scores and attendance data have so far functioned merely as administrative archives, making it difficult to identify patterns of student performance. This study aims to classify students based on academic achievement and discipline by applying the K-Means Clustering algorithm using RapidMiner. The data used in this study consist of scores from six subjects and attendance records of 35 students from the Light Vehicle Engineering (TKR) department over two semesters. The data were obtained from original school records, compiled using Microsoft Excel, and processed in RapidMiner. The clustering process employed four clusters for academic achievement and two clusters for discipline, with Euclidean Distance used as the similarity measure. The results show that in the first semester, students were grouped into four academic achievement clusters: high achievement (6 students), moderate achievement (7 students), potentially problematic (14 students), and problematic (8 students). In the second semester, the distribution changed to high achievement (19 students), moderate achievement (14 students), potentially problematic (4 students), and problematic (1 student). Meanwhile, student discipline was divided into two clusters: disciplined (31 students) and undisciplined (4 students). These results demonstrate that K-Means Clustering is effective in mapping student conditions, revealing patterns in academic performance and attendance, and supporting educational evaluation, learning planning, and early detection of students who require academic or disciplinary intervention. Keywords: Data Mining, K-Means Clustering, Academic Achievement, Discipline, RapidMiner, Vocational High School (SMK)

Post-disaster settlement recovery requires more than the provision of permanent housing; it demands an integrated approach covering social, economic, institutional, environmental, and disaster risk reduction dimensions. This study analyzes the Settlement Planning Document (RPP) of the Sibalaya Selatan Satellite Permanent Resettlement Area (Huntap) in Sigi Regency, Central Sulawesi, which accommodates 118 households displaced by the 2018 Palu liquefaction disaster. The research examines the RPP as a participatory planning instrument for sustainable post-disaster recovery. A qualitative participatory approach using the Community Action Plan (CAP) method was conducted from July to November 2024 through focus group discussions, participatory workshops, formation of a Core Planning Team (TIP), field observations, document reviews, and public consultations. Data were analyzed using descriptive, infrastructure, spatial, and strengths-problems-opportunities-challenges frameworks. The findings reveal that community social capital, reflected in active organizations, social networks, and digital communication infrastructure, has been transformed into economic capital. In addition, four dimensions of community resilience economic, social, communication, and competence capacities were identified at varying levels of development. The TIP also played a strategic role in integrating the RPP into village and regional development planning. The resulting RPP contains 39 priority programs valued at approximately IDR 340.6 million for 2024-2028 across infrastructure, economic, social-environmental, and disaster risk reduction sectors. The study demonstrates that the CAP approach effectively supports sustainable settlement development and offers a replicable model for post-disaster resettlement areas in Indonesia.

The presence of Generation Z, who grew up entirely in the digital era, has triggered a fundamental transformation in Muslim religious practices, where social media has replaced conventional religious institutions as the primary source of religious information. This condition creates a paradox: Gen Z has become a generation that is highly religious online, yet is often disconnected from physical communities and traditional religious authorities. This study aims to analyze the character of Muslim Gen Z religiosity, identify its forming factors, and examine the impact of the digital era on their religiosity. This study employed a descriptive qualitative approach using a library research method. The findings indicate that Muslim Gen Z religiosity is characterized by personalization, flexibility, and digital spirituality, strongly influenced by social media. These characteristics are shaped by massive digital technology accessibility, the effectiveness of contextual Islamic preaching on platforms such as TikTok, as well as spiritual needs and social pressure from the digital environment. The digital era brings positive impacts in the form of increased accessibility and religious literacy, but also negative impacts including shallow religious understanding, vulnerability to information bias, and potential exposure to extreme ideologies. This study implies the importance of an integrated digital religious literacy strategy through critical thinking-based Islamic Religious Education curriculum reform, enhancement of educators' digital capacity, and cross-sector collaboration to strengthen Gen Z's moderate and reflective religious understanding.

This research aims to analyze the implications of the transition in lease accounting standards to PSAK 73 on tax efficiency levels and net income structures within the retail industry, focusing on PT Mitra Adiperkasa Tbk as case studies. Employing a descriptive quantitative method, this research compares financial statement data from the 2017-2024 period to evaluate shifts before and after the regulation's enforcement. The results reveal that the implementation of PSAK 73 successfully improved corporate tax efficiency, characterized by a decrease in the Effective Tax Rate (ETR) below the statutory corporate tax rate. This was achieved by leveraging temporary differences that resulted in the recognition of deferred tax assets, providing a strategic advantage in the form of tax deferral. On the other hand, the application of this standard caused significant pressure on net profit during the initial transition phase due to the front-loading expense pattern derived from right-of-use asset depreciation and lease liability interest.

This research aims to analyze students' learning climate through the application of the Project Based Learning (PjBL) in mathematics learning in class II of Public Elementary School 002 Palembang. This study used a qualitative descriptive method with the study subjects of grade II students. Data collection techniques are conducted through observation, interviews, and documentation. Data analysis is conducted through the stages of data reduction, data presentation, and conclusions drawn. Research results show that the application of the PjBL model is able to form a more conducive learning climate, characterized by increased focus, attention, and student involvement in the learning process. In addition, interactions between students are becoming more directed, group collaboration is getting better, and activities that interfere with learning can be minimized. Project-based activities involving kinesthetic activities such as shearing and sticking help students become more active, creative, and easier to understand the concept of right triangles more concretely. Student-centered learning also provides an opportunity for them to learn independently and in groups so that the learning experience becomes more meaningful. Thus, the application of the PjBL model can be an effective learning alternative in creating an active, conducive, and enjoyable learning atmosphere for elementary school mathematics and supporting the achievement of learning goals optimally.

This article examines the re-actualization of teachers’ social competence within the digital learning ecosystem.

The population consisted of all students actively participating in Scout and SISPALA activities. Using total sampling, 24 students were selected as respondents. Data were collected through questionnaires and documentation and analyzed using simple and multiple linear regression with SPSS. The findings revealed that Scout coaching had a positive and significant effect on students’ character development (t = 4.083, p = 0.000 < 0.05). SISPALA coaching also had a positive and significant effect (t = 2.888, p = 0.009 < 0.05). Simultaneously, Scout and SISPALA coaching significantly affected students’ character development (F = 11.911, p = 0.000 < 0.05). The coefficient of determination (R² = 0.531) indicated that 53.1% of the variance in character development was explained by Scout and SISPALA coaching.

Typhoid fever during pregnancy can lead to complications such as uteroplacental infection, miscarriage, and vertical transmission, which causes neonatal typhoid. Typhoid fever is found worldwide and is highly prevalent in developing countries, particularly in tropical regions. It is estimated that there are 11–21 million cases per year and approximately 128,000–161,000 deaths per year; the majority of cases occur in Southeast Asia, South Asia, and Sub-Saharan Africa. Salmonella typhi is a gram-negative bacterium capable of intracellular survival. Symptoms in typhoid patients vary among different groups. While pregnant women with typhoid are more likely to exhibit coughing, non-pregnant patients more frequently report nausea/vomiting compared to pregnant patients. The effects of typhoid fever on pregnancy result from prolonged high fever and poor general health, which can lead to miscarriage, preterm labor, and intrauterine fetal death, especially if the infection occurs during the first or second trimester. Morbidity and mortality rates may be higher in pregnant women. Pregnancy itself does not affect the course of the disease. Prevention of typhoid fever involves adopting a clean and healthy lifestyle, as well as receiving the typhoid vaccine. Two effective vaccines are available for typhoid fever. The live-attenuated oral vaccine (Ty21a) requires four doses, administered 48 hours apart, without concurrent use of antibiotics or antimicrobial medications. Due to reduced gastrointestinal motility in early pregnancy and frequent nausea and vomiting associated with symptomatic gastroesophageal reflux requiring acid-reducing therapy, we do not recommend the Ty21a oral vaccine for pregnant patients.

Land rights disputes arising from overlapping land certificates remain a complex agrarian law issue frequently encountered in Indonesia. This phenomenon reflects weaknesses in the land administration system, particularly in data collection, land measurement, and certificate issuance. Such disputes create conflicts, legal uncertainty, and reduced public trust in the land registration system. In practice, these disputes are generally resolved through civil litigation procedures in the District Court. This study aims to comprehensively analyze civil procedural law in resolving land rights disputes involving overlapping certificates and to examine the evidentiary strength of land certificates in judicial proceedings. This research employs a normative legal method using statutory and conceptual approaches, supported by primary and secondary legal materials. The findings indicate that dispute resolution begins with the filing of a lawsuit, followed by mediation, court examination, and the evidentiary process as the most crucial stage in determining lawful ownership. Land certificates serve as strong evidence; however, they are not absolute, as they may be challenged if administrative or substantive legal defects are identified. Judges play a central role in assessing certificate validity by considering land history, physical possession, good faith, and compliance with legal procedures. Nevertheless, the effectiveness of dispute resolution still requires improvement through better land administration, enhanced data accuracy, and stronger institutional integration.

This study aims to analyze the process of internalizing legal values in the formation of a culture of law-abidingness by emphasizing the perspective of civic responsibility and the Islamic Sociological Jurisprudence Theory approach. The main problem studied is how legal values are not only understood normatively, but also internalized in the individual and collective consciousness of society, thus giving rise to sustainable law-abiding behavior. The research method used is a normative juridical approach with strengthening conceptual and sociological analysis of legal dynamics in society. The results show that the internalization of legal values is a multidimensional process involving cognitive, affective, and spiritual aspects, which are influenced by education, the social environment, role models, and the consistency of law enforcement. In the context of civic responsibility, a culture of law-abidingness is not only formal compliance with regulations, but also reflects moral awareness and active participation of citizens in maintaining social order. Meanwhile, Islamic Sociological Jurisprudence Theory offers an integrative paradigm that combines the normative dimensions of sharia with social reality, through a comparative approach of schools of thought, maqāṣid al-syarī‘ah, and an orientation toward the welfare of the people. This research emphasizes that the formation of an effective culture of law-abidingness requires a holistic and contextual approach, in which law is understood as a living and adaptive social instrument. Thus, the internalization of legal values based on civic responsibility and an Islamic sociological jurisprudence approach can encourage the realization of substantive justice, high legal awareness, and a civilized and sustainable social order.

The development of digital technology has brought about significant changes in various aspects of life, including early childhood faith education. Today’s children are growing up in an environment familiar with digital media, making it necessary to adopt a catechetical approach that keeps pace with the times. This article aims to examine the use of digital catechesis as a tool for early childhood faith education. This study employs a qualitative method with a literature review approach, gathering data from books, scientific journals, research articles, Church documents, and other relevant sources. The data is analyzed using descriptive-qualitative methods to understand the benefits, challenges, and role of digital catechesis in fostering children’s faith. Research findings indicate that digital catechesis can serve as an effective, engaging, and interactive medium for helping children learn about the teachings of the faith from an early age. The use of animated videos, religious songs, educational images, and learning apps can enhance children’s interest in learning, attention, and understanding of Catholic faith values. Furthermore, digital catechesis also assists the Church, families, and schools in providing faith education that is more contextual and aligned with the world of today’s children. However, the use of digital media still requires the guidance of parents, teachers, and faith mentors so that children receive proper direction and are protected from the negative impacts of technology. Thus, digital catechesis is a relevant tool in the faith education of young children when used wisely and purposefully. The presence of digital media does not replace the role of faith educators but serves as a tool that enriches the process of proclaiming the faith in the modern era.
