Adolescence is a transitional period marked by rapid biological, psychological, and social changes, which often lead to various problems for individuals, particularly at the high school level. This study aims to analyze the role of guidance and counseling services in addressing these issues using a literature review approach. The method employed is a systematic literature review of relevant scientific publications from 2020 to 2026. The data collection process was carried out through the search, selection, and evaluation of literature related to student issues and guidance and counseling services in schools. The research findings indicate that students face various challenges, such as difficulties in learning, low academic ability, academic stress and anxiety, as well as social-emotional issues influenced by internal and external factors. Guidance and counseling services play a role in supporting students to self-reflect, overcome problems, and optimize their potential through preventive, curative, and developmental approaches. The success of these services is also supported by the role of counselors, collaboration with other teachers, and parental participation. However, in practice, there are still a number of obstacles, such as limited human resources, a lack of coordination, and an incomplete understanding of the functions of these services. Therefore, efforts are needed to improve implementation and cooperation so that guidance and counseling services can operate more efficiently.

Differential equations involve derivatives of unknown functions and are widely used in mathematical modeling of various real-world problems. They can be classified based on linearity, homogeneity, coefficients, number of independent variables, degree, and order, thus requiring appropriate solution methods. One commonly used approach is the reduction of order method, which simplifies equations by reducing their order step by step. However, this method generally requires the solution of the corresponding homogeneous equation as an initial step. This study aims to solve nonhomogeneous linear ordinary differential equations of order with constant coefficients using the reduction of order method without determining the homogeneous solution. This research is a theoretical study based on relevant references concerning solution methods and types of differential equations. The procedure consists of two main stages: determining the fundamental symmetric polynomial variables based on the coefficients and constructing a sequence of solutions through first-order linear differential equations obtained from the reduction process. The results show that this method systematically produces the general solution of linear differential equations of order , making it an effective and efficient alternative approach

This study aims to analyze students’ mathematical reasoning abilities in quadratic function material through the use of Desmos. The research employed a qualitative descriptive approach using a case study and usability testing method. Data were collected through post-tests and interviews involving students’ responses in solving quadratic function problems. The analysis focused on several indicators of mathematical reasoning, including procedural skills, conceptual understanding, and analytical ability. The results show that students generally demonstrate adequate procedural reasoning, particularly in substitution and computation tasks. They are also able to relate algebraic representations to geometric interpretations, such as determining intercept points and analyzing the direction of parabolas. However, limitations were found in conceptual understanding, especially in identifying graph characteristics without relying on procedural steps. The use of Desmos significantly supports the development of students’ mathematical reasoning by providing real-time visualization, facilitating exploration of function parameters, and enabling verification of results. Overall, Desmos contributes to enhancing procedural, conceptual, and analytical dimensions of mathematical reasoning, although its effectiveness depends on proper instructional design.

Counseling etymologically derives from the noun counsel, which originates from the Latin consilium, rooted in consilere, meaning “to consult,” or to seek the views and advice of others as guidance for consideration and decision-making. As a verb, to counsel or counseling refers to the act of providing advice, guidance, warnings, encouragement, and instruction aimed at fostering self-surrender in addressing problems and managing negative behaviors among students. Educational guidance and counseling aim to strengthen Christian students to live victoriously in the Lord Jesus Christ by bringing them to an understanding of the light of God’s Word and the acceptance of themselves as God’s grace. This Classroom Action Research was conducted to address and resolve the problems of Christian students based on the research formulation, particularly through the application of intellectual, moral, and social approaches as strategic steps to enhance educational counseling services. The study employed a qualitative approach, with data collected through in-depth interviews and field notes. Data analysis was carried out by categorizing findings to generate emerging themes. In-depth interviews and focus group discussions were conducted with three teacher participants and two student participants. The findings revealed that several students required special attention due to tendencies toward delinquent behavior, while one case indicated a student’s involvement in narcotics. These findings demonstrate that student-related issues require special intervention efforts to improve their spiritual and mental well-being, leading them to a deeper knowledge of the Lord Jesus Christ as their personal Savior. The ultimate goal is the salvation of students’ souls and the glorification of the name of the Lord Jesus Christ.

In recent years, the Iran–United States conflict has not only unfolded within the geopolitical arena but has also been intensively constructed through international media framing that shapes how global audiences understand this reality. In the context of the digital information overflow, media no longer function merely as conveyors of facts; rather, they act as agents that construct meaning, evoke emotions, and shape the social perceptions of audiences. This study aims to analyze how international media framing constructs representations of the Iran–United States conflict and how audiences interpret such discourse within their social experiences. This research adopts a qualitative approach with a Critical Discourse Analysis (CDA) design. Data were collected through document analysis of 25 news articles from both Western and non-Western media, as well as exploratory interviews with nine participants from academic backgrounds. Data analysis was conducted using a thematic approach based on Norman Fairclough’s three-dimensional model. The findings reveal three main patterns: the construction of threat through media language, moral polarization that produces a dichotomy of “us versus them,” and the negotiation of meaning by audiences, which is reflective and not always linear. These findings indicate that audiences are not entirely passive; rather, they actively interpret and, at times, question media framing. Theoretically, this study extends Critical Discourse Analysis by incorporating the dimension of audience experience into the discursive process. Practically, it underscores the importance of critical media literacy in navigating the complexity of global information and opens avenues for further exploration of the relationship between discourse, power, and social experience.

This study aims to explore the meaning of service excellence from the perspective of hotel employees at Kinasih Resort Depok, Indonesia. Most existing research on service excellence has focused on guest satisfaction, leaving the subjective experiences of employees as service providers underexplored. This study employs a qualitative approach with a descriptive phenomenological design. Data were collected through in-depth interviews, participatory observation, and documentation from five purposively selected informants across the F&B Service, Housekeeping, Front Office, Human Resources, and management departments. Data analysis followed Moustakas's phenomenological procedure encompassing epoché, horizonalization, theme clustering, and essence description. Findings reveal that employees construct layered meanings of service excellence according to their hierarchical positions: frontline workers emphasize friendliness and responsiveness, supervisors emphasize speed and problem resolution, while management frames it as a holistic service ethos encompassing internal relationships. Emotional labor emerged as an inevitable dimension managed through collaboration, prioritization, and de-escalation strategies. Organizational factors including training systems, communicative leadership, guest feedback-based evaluation, and managerial attention to employee well-being demonstrably shape how employees internalize service excellence values. This study contributes to employee-centered literature on service excellence and offers practical implications for human resource development in resort contexts.

Biology learning in Indonesia is still predominantly teacher-centered, limiting students’ opportunities to actively develop critical thinking, creativity, collaboration, and other 21st-century competencies. Students often receive information passively, resulting in low engagement and limited ability to apply concepts in real-life contexts. Therefore, innovative learning models are needed to support more meaningful and student-centered learning. This study aims to review the implementation of Project-Based Learning (PjBL) in Biology education and analyze its contribution to the development of students’ 21st-century skills. The study employed a literature review method by analyzing 20 research articles published between 2022 and 2026. Articles were obtained through Google Scholar searches and selected based on relevance to Biology education, focus on PjBL implementation, and open-access availability. Data collection involved identification, screening, selection, and documentation of related studies, while data analysis used a qualitative descriptive approach. The findings indicate that PjBL effectively improves students’ cognitive achievement, conceptual understanding, scientific literacy, creativity, and critical thinking skills. In addition, PjBL enhances collaboration, communication, problem-solving abilities, learning motivation, and life skills through contextual and authentic project activities. Students become more actively involved in investigating real-world problems, designing solutions, and producing meaningful learning outputs. Furthermore, the integration of STEM approaches, digital media, blended learning, and Culturally Responsive Teaching (CRT) strengthens the effectiveness of PjBL in Biology learning. Overall, PjBL is highly relevant for supporting the Merdeka Curriculum and improving the quality of Biology education in developing 21st-century competencies.

Abstract: The digital era demands that every individual possess visual literacy competencies, but in Islamic boarding schools (pesantren), access to technology is often limited to maintain focus on worship. The main problem at the Salafiyah Al-Furqon Islamic Boarding School in Sawangan, Magelang Regency, is the digital skills gap among 12th-grade students. This is caused by the boarding school's policy of only allowing mobile phone use during semester breaks, leaving students lacking practical multimedia skills prior to graduation. This community service activity aims to provide a solution through basic photography and videography training as a soft skill for alumni independence. The method used is a workshop that combines theoretical explanations and direct practice (experiential learning). The results of this activity show a significant increase in students' technical competency; participants are able to operate smartphone cameras with stable shooting techniques, understand the principles of visual composition (such as the rule of thirds and leading lines), and are able to perform basic video editing using mobile-based software applications. Through this training, Islamic boarding school graduates are expected to become individuals who are adaptive to technological developments and able to utilize visual media as a means of creative economics and digital da'wah after graduation.

Industrial dust exposure is a hazardous work environment that can potentially cause respiratory problems in workers, particularly in industrial sectors with production activities that generate high levels of dust particles. This study aims to examine the relationship between industrial dust exposure and respiratory problems in workers through a systematic review. The method used was a qualitative descriptive literature study of scientific articles from 2021-2026 obtained through Google Scholar based on inclusion and exclusion criteria, then systematically analyzed. The results of the study indicate that most studies found a significant relationship between dust exposure and respiratory problems, especially in work environments with dust levels exceeding the threshold limit (TLV). Common symptoms include coughing, shortness of breath, phlegm production, and decreased lung function. In addition to dust levels, other factors such as duration of exposure, length of service, smoking habits, and the use of personal protective equipment (PPE) also play a role in increasing the risk. However, several studies showed insignificant results, which are suspected to be influenced by the use of proper PPE and an effective work environment control system. These findings confirm that dust exposure is a significant, multifactorial risk factor, necessitating comprehensive control efforts through a hierarchy of controls, environmental monitoring, and regular health checks to prevent long-term impacts on worker health.

Nutritional problems among children under five, particularly stunting, remain a significant public health challenge associated with inadequate nutrient intake and unfavorable eating behaviors such as picky eating, poor appetite, and feeding difficulties.

Every nation, including Indonesia, has a problem with population growth. A high birth rate is the consequence of an expanding population, which causes childhood malnutrition. Family planning is an attempt to regulate the quantity and spacing of children. The AKDR is the recommended method of contraception. Indonesia's AKDR coverage is still inadequate. Because the husband is the head of the household, his support is crucial since he has the power to decide whether or not to use contraception. At the Ibu Community Health Center, this research aims to explore the connection between husband support and a lack of interest in using IUD contraception among couples of reproductive age. With 25 individuals in the study group, a cross-sectional research design with total sampling methodologies was employed. A survey was used as the research method, and the data was subjected to Chi-Square analysis with SPSS. The chi-square statistical test produced a P-value (asymp. Sig 2-tailed) of 0.000 < 0.05, indicating that there is a correlation between husband support and a low desire among couples of reproductive age to utilize IUD contraception. Consequently, since H0 was disproved and H1 was proven, it can be inferred that there is a link between husband support and couples of childbearing age having a low interest in using IUD contraception.
