A suitable and targeted marketing plan is required because of the intense competition in the retail drinking water sector. Customer segmentation using RFM (Recency, Frequency, and Monetary) analysis is one of the techniques employed. Additionally, K-Means clustering, a clustering technique based on machine learning, is employed. This study's goal is to present the findings in the form of graphs that can be used to examine consumer trends according to their attributes. With a value of 10286, the Calinski Harabaz index is a suitable metric to move on to the segmentation step in this study, which also tests three metrics using the clustering method. An ideal cluster is created for every cluster evaluation by dividing the Calinski Harabaz index into three more manageable clusters. This contrasts with other evaluation metrics that only yield two clusters. For instance, when XYZ drinking water sales transaction data was distributed, it was discovered that, out of the total drinking water sales, woodsale had 422 customers, diamond had 1061 customers, and star diamond had 2005 customers. The management of the XYZ drinking water company and other marketing fields are expected to encounter more intense competition as a result of the study's findings.

Best graduate selection is crucial for academic achievement and contributes to the accreditation value of the institution. Instituto Profissional de Canossa (IPDC) is a higher education institution founded by the Canossian Sisters in Timor-Leste. To improve the effectiveness of assessment and decision-making processes, an information system is needed to assist in selecting the best graduates based on multiple criteria. This research develops a web-based Decision Support System (DSS) using the Multi-Attribute Utility Theory (MAUT) method. MAUT is a multi-criteria decision-making method that evaluates alternatives based on their utility scores across several criteria. The study uses four main criteria: attendance, academic performance, ethics, and discipline. The system is implemented as a web application for universal access. The MAUT calculation results provide valid and accurate recommendations for the best graduates. System testing showed that the application successfully ranked candidates based on defined weights and criteria, providing objective and consistent selection results.

This study aims to: 1) describe the classical interpretation of QS. An-Nisa' [4]:9, particularly the concept of protecting descendants (khaufu 'ala al-dzurriyah); 2) explain the moral message of QS. An-Nisa' [4]:9 regarding parental responsibility through Abdullah Saeed's contextual hermeneutical framework; 3) demonstrate how a reinterpretation of QS. An-Nisa' [4]:9 can provide a new, more positive, and more balanced perspective on the childfree phenomenon in contemporary society. This research adopts a qualitative method grounded in library research. The data sources include classical and contemporary tafsir works, the writings of Abdullah Saeed, thematic literature on family studies, and academic references discussing the modern emergence of the childfree phenomenon. The analysis applies a contextual hermeneutical approach that emphasizes reading the Qur'anic verse through its historical setting, universal moral values, and relevance to contemporary social realities. This approach enables an integrated understanding between the fundamental message of the verse and present-day ethical challenges. The findings reveal that classical interpretations of QS. An-Nisa' [4]:9 focuses on the protection of orphans and the obligation to prevent descendants from falling into states of weakness. The moral message of the verse, viewed through Abdullah Saeed's framework, directs attention to the heavy moral responsibility of raising children, which requires comprehensive readiness. The reinterpretation of the verse highlights that the childfree choice does not inherently conflict with Islamic values, as this decision may arise from moral responsibility to avoid producing descendants who may be at risk of weakness, as warned in the verse. This perspective encourages society to view childfree choices more positively and aligns them with the Qur'anic objective of safeguarding the well-being and strength of future generations.

These findings demonstrate Random Forest’s effectiveness in churn prediction and provide practical insights for customer retention strategies

Software Defined Network is a popular computer network concept today because of the ease of managing network traffic with the control plane. Massive internet usage makes web server services on SDN networks overloaded. There are many load balancing concepts to overcome this problem, one of which is implementing the K-NN algorithm. This study aims to maximize the performance of the K-NN algorithm on SDN networks by optimizing the K value using Grid Search Cross Validation, and adding server status selection logic based on the smallest disk if the server status calculated by K-NN has the same. All implementations of the load balancing concept in this study were created virtually using Open vSwitch and virtualbox. Testing was carried out using CPU, MEMORY, and DISK parameters sent by the server with the help of the psutils component. JMeter software was used for testing by sending data using the POST method. The data type is text/plain with a data size of 1MB, testing was carried out in stages with threads 100, 200, 300, 400. The test results showed that the performance of the K-NN algorithm was running optimally. There was no significant difference in the distribution of the load to the server, this made the optimization and addition of logic successful.

Schools are formal educational institutions that play a crucial role in transferring knowledge and shaping students' cognitive, psychomotor, and character development systematically and responsibly. While the "school of life" is often defined as a non-formal learning space, formal schools retain a strategic position because they provide a clear ontological, epistemological, and axiological framework, including in the formation of students' character and self-concept. However, the reality on the ground shows that labeling practices are still prevalent in the school environment, both by teachers and fellow students, which negatively impact students' psychological, emotional, social, and self-concept. Negative labels such as stupid, lazy, naughty, or physical and social labels have been shown to cause "invisible wounds" that affect students' self-esteem and functioning in the long term. This study uses qualitative methods through a literature review to examine the phenomenon of labeling and its impact on the formation of students' self-concept within the framework of Christian Character Education. The results of the study indicate that Christian Character Education, which is based on the values ​​of love, acceptance, and respect for human dignity as God's creation, has a strategic role in restoring the self-concept of students affected by labeling. Christian character education not only instills moral and ethical values, but also builds students' inner and spiritual resilience so that they are able to interpret themselves positively, regardless of the negative labels they receive.

The rapid development of digital technology has brought significant changes to social life, particularly among university students as an educated group and agents of change. On the one hand, digital spaces provide opportunities for freedom of expression and public participation; on the other hand, they also present various challenges related to Human Rights (HR), such as privacy violations, the spread of hate speech, disinformation, and cyberbullying. These conditions highlight the importance of strengthening students’ capacity to ensure they possess adequate understanding and awareness of human rights values in the digital era. This community service article aims to enhance students’ human rights awareness through capacity-building activities conducted within the university environment. The service method was implemented through educational activities in the form of seminars, material presentations, and interactive discussions addressing fundamental human rights concepts, digital ethics, privacy protection, and responsible freedom of expression.The results of the activities indicate an increase in students’ understanding and awareness of human rights issues in the digital era, as well as the development of more critical and ethical attitudes in utilizing digital spaces. This initiative also strengthened the synergy between higher education institutions and the government in promoting human rights awareness among students. Overall, this community service activity makes a positive contribution to strengthening students’ capacity to face human rights challenges in the digital era.

This study examines the relationship between Dayak cosmology and Christian spirituality through the inculturation of the Munjong tradition within Catholic Dayak Tobak communities in Dusun Batu Besi, Desa Sejotang, West Kalimantan. As a post-harvest thanksgiving ritual, Munjong embodies a symbolic framework reflecting the interconnectedness of humans, nature, ancestors, and Jebata within the Dayak worldview. The tradition functions not only as a religious expression but also as a means of preserving cultural identity and fostering social cohesion. Within a predominantly Catholic context, Munjong has undergone reinterpretation, aligning with Eucharistic spirituality as the Church’s central expression of gratitude. Using a descriptive-qualitative approach combined with symbolic interaction analysis, this study shows that the religious values embedded in Munjong, including: gratitude, petitions for protection, and veneration of ancestors as spiritual mediators, correspond with Catholic teachings on divine providence, the communion of saints, and the sacredness of creation. The local Church recognizes Munjong as a cultural practice suitable for inculturation, provided it aligns with Christian doctrine, thereby offering opportunities for contextual liturgy and catechesis. The findings suggest that Munjong can serve as a bridge between faith and local culture while simultaneously reinforcing cultural identity and deepening the spiritual life of the community. The result of this study contributes to the discourse on inculturation, contextual pastoral practice, and strategies for sustaining indigenous traditions amid social change.

First-year university students undergo a transitional phase from the school environment to the academic, social, and emotional demands of higher education. This transition often triggers stress when not supported by an adequate social environment. Peer support plays an essential role in this adaptation process by providing emotional support, information, and a sense of belonging. Positive peer relationships can help students manage academic pressure, whereas poor peer interactions may increase the risk of stress. Therefore, peer support serves as a protective factor in maintaining the psychological well-being of first-year students. This study employed a quantitative approach with a cross-sectional design. Data were collected using the Peer Support Questionnaire (PSQ) and the Student-Life Stress Inventory (SSI) from 130 first-year students of the Faculty of Pharmacy, UNISSULA. The sampling technique used was simple random sampling. Data were analyzed using the Gamma correlation test to determine the relationship between the variables. The Gamma test revealed a p-value of 0.000 (<0.05), indicating that the alternative hypothesis was accepted, meaning there is a significant relationship between peer support and stress levels among first-year students. The correlation coefficient of –0.737 indicates a strong negative relationship, suggesting that higher peer support is associated with lower stress levels. There is a significant and strong relationship between peer support and stress levels among first-year students at the Faculty of Pharmacy, UNISSULA.

This community service program aimed to strengthen national insight and soft skills among ADik scholarship students through a participatory and reflective mentoring approach. Many students come from underdeveloped, frontier, and outermost regions with diverse socio-cultural backgrounds, requiring contextual guidance to internalize national values and develop essential interpersonal competencies. The program combined interactive socialization, group discussions, and value reflection activities to encourage active participation and personal engagement. The method emphasized dialogic learning rather than one-way lectures, allowing students to relate national values to their lived experiences. The findings revealed noticeable behavioral changes, including increased confidence in expressing opinions, stronger participation in discussions, improved communication skills, and heightened awareness of ethical conduct and financial responsibility as scholarship recipients. The emergence of several students as informal local leaders during discussions indicated early signs of social transformation at the individual level. This program demonstrates that reflective and participatory mentoring can effectively foster character building, leadership, and contextual national awareness among university students. The implications suggest that similar approaches can be adopted in student development programs to promote sustainable character formation, especially for students from diverse and remote regions.

Physiological changes in adolescents during the transition period, both biologically, cognitively, psychosexually, and psychosocially, are very vulnerable to various risky behaviors such as premarital sexual behavior, abortion, unwanted pregnancy, STIs, and drug use. One effort to increase adolescent awareness about premarital sex is health education. This study identified the effectiveness of audiovisual media and leaflets about premarital sexual behavior on the knowledge and attitudes of adolescents at SMA Negeri 20 Seram Bagian Barat. The study used a quasi-experimental approach, pre-post-test control group design, with 40 samples. The Wilcoxon test results for the intervention group showed a p-value of 0.001 (p < 0.05), indicating a significant difference in adolescent knowledge and attitudes before and after health education using audiovisual media. The control group showed a p-value > 0.05, indicating no significant difference in adolescent knowledge and attitudes before and after health education using leaflets. The Man-Whitney test results showed a p-value < 0.000 (p value < 0.05) for the intervention group post-test. It was concluded that there was a significant difference in health education using audiovisual media and leaflets regarding premarital sexual behavior on adolescent knowledge and attitudes at State Senior High School 20, West Seram.  

News texts are a systematic way of conveying information that contains declarative and imperative sentences used to convey meaning directly and demonstrate the persuasive value of the news. The research goals are to analyze imperative sentences to understand how commands, requests, prohibitions, or invitations are conveyed so that they can influence the actions or responses of readers, as well as to analyze declarative sentences, which play an important role in constructing discourse structure and indicating the writer's position on the topic being discussed. This study was conducted using a qualitative descriptive method. This method was chosen because it can describe what is seen, heard, felt, and asked. The researcher considers qualitative descriptive research to accurately describe a situation without manipulating variables.  This research concludes that imperative sentences elicit responses in the form of agreement and action, or rejection, either directly or indirectly. Meanwhile, declarative sentences serve as a guide or basis for understanding the context the speaker wishes to convey and can also be used to reinforce previously conveyed information to avoid ambiguity and misunderstanding when examining the meaning. This research is expected to be useful in linguistic studies, more specifically in syntactic material that discusses declarative and imperative sentences in news texts and political discourses.

Result: The Wilcoxon Signed Rank Test showed a p-value of 0.000 (p < 0.05), indicating a significant difference between pain levels before and after the intervention. These findings demonstrate that the combination of Murottal Surah Ar-Rahman and lemon aromatherapy is effective in reducing dysmenorrhea pain among female adolescents at SMA Negeri 10 Semarang. Conclusion: The combined therapy of Murottal Surah Ar-Rahman and lemon aromatherapy is effective in reducing dysmenorrhea pain levels among female adolescents.  

The enforcement of election criminal law plays a crucial role in safeguarding democratic integrity and upholding the principle of popular sovereignty. Law Number 7 of 2017 establishes the Integrated Law Enforcement Center (Sentra Gakkumdu) as a coordinated mechanism involving the Election Supervisory Body, the Police, and the Prosecution Service in addressing election crimes. However, in practice, the Gakkumdu system has not fully ensured a balanced realization of legal certainty, substantive justice, and legal utility. This study aims to analyze the problems of election criminal law enforcement within the Gakkumdu system, examine the relevance of the Restorative Justice approach in election law, and formulate a reconstruction of election criminal law enforcement based on this approach. This research employs normative legal research using statutory, conceptual, legal philosophy, and legal policy approaches. The findings indicate that the weaknesses in election criminal law enforcement arise from institutional fragmentation, normative ambiguity, and a legal culture dominated by legalistic and sectoral perspectives. The Restorative Justice approach is considered relevant as it prioritizes substantive justice and the restoration of democratic values. Therefore, reconstructing election criminal law enforcement based on Restorative Justice is essential to strengthening democratic legitimacy and public trust in elections in Indonesia.

Character education faces significant challenges due to digital disruption and globalization that trigger moral degradation in adolescents. In Purwakarta Regency, the "7 Poe Atikan" policy through Regent Regulation No. 69 of 2015 was implemented as a transformative solution based on local wisdom.
