The language used in online news is not only a tool for conveying information but also shapes perspectives that influence readers. One key element in this aspect is phrases. Phrases always appear in various types of text. A phrase is a grammatical unit consisting of two or more words that does not exceed the functional limit and fulfills one of the syntactic functions. Phrases are often found in a text within a sentence, one of which is on the online news page cnnindonesia.com. The type of phrase found in the news page is a verb phrase that functions to form a predicate, link ideas, and better explain the author's intent. The cnnindonesia.com page about Affan Kurniawan published in August 2025 was chosen because it shows a variety of verb phrases that are interesting to study. This study aims to describe the form of verb phrases found in the cnnindonesia.com news about Affan Kurniawan published in August 2025. This research can provide a clearer picture of verb phrases in journalistic texts. The research method used is a qualitative descriptive method. The results of this study describe verb phrases and their syntactic functions in a cnnindonesia.com news story about Affan Kurniawan published in August 2025. This research is useful theoretically and practically. Theoretically, this study enriches the syntactic study of verb phrases and their application in media texts. Practically, the results can serve as a reference for students, researchers, and journalists in using Indonesian effectively and according to the rules.

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.

The increasing rate of divorce in rural areas indicates serious challenges in maintaining family resilience as well as the limited effectiveness of formal litigation-based dispute resolution. Judicial processes that tend to be procedural, time-consuming, and focused on legal termination often fail to address the substantive justice needs of the disputing parties. Consequently, alternative dispute resolution mechanisms that are more responsive to local social and cultural values are required. This study aims to examine the effectiveness and implementation of divorce mediation facilitated by the Village Government of Banra’as, Sumenep Regency, through the perspective of Progressive Legal Theory. This research employs a qualitative approach with an empirical research design. Data were collected through field observations, in-depth interviews with village officials, community leaders, and individuals who had previously participated in the mediation process, as well as documentation related to divorce dispute resolution practices at the village level. Data analysis was conducted using a descriptive-analytical method, focusing on mediation practices as a manifestation of living law within the community. The findings reveal that divorce mediation facilitated by the village government demonstrates a relatively high level of effectiveness in reducing divorce cases. This effectiveness is influenced by a familial approach, the utilization of local wisdom, and the strong internalization of religious values within the social life of the Banra’as community. From the perspective of Progressive Legal Theory, this mediation practice reflects a flexible and non-positivistic understanding of law that prioritizes humanity and substantive justice. Village-based mediation not only serves as an alternative dispute resolution mechanism but also functions as a social instrument to preserve family harmony and strengthen social resilience in rural communities.

The stability of disposal slopes is a critical aspect of open-pit mining operations because it directly affects operational safety and the continuity of overburden dumping activities. Disposal areas composed of overburden materials generally exhibit heterogeneous characteristics, particularly when soft materials such as mud are present, which can significantly reduce slope stability. Therefore, a comprehensive slope stability evaluation is required prior to further disposal development. This study aims to assess the stability condition of a disposal slope under initial conditions, evaluate the influence of material conditions, and analyze the effectiveness of counterweight application in improving both the safety factor and disposal capacity. The research methodology involved the collection of primary and secondary data, including slope geometry, lithological conditions, and the physical and mechanical properties of disposal materials obtained from laboratory testing and company technical data. Slope stability analysis was performed using the limit equilibrium method with the assistance of geotechnical software, taking into account groundwater conditions and operational loading. The analysis results indicate that the initial disposal condition yielded a safety factor of 0.718, indicating an unstable slope condition. After simulating the removal of mud material, the safety factor increased to 0.907 but remained below acceptable stability criteria. The application of a counterweight significantly improved slope stability, resulting in a safety factor of 1.498. Further optimization through slope geometry redesign produced a final safety factor of 1.101, which satisfies the requirements stipulated in KEPMEN ESDM No. 1827 K/30/MEM/2018. Additionally, the redesign increased the disposal capacity from 119,507,864.23 LCM to 119,682,378.22 LCM, representing an increase of 174,513.99 LCM. These results demonstrate that counterweight application combined with geometric optimization is effective in enhancing both slope stability and disposal capacity.

Nutritional status plays an important role in shaping body image among adolescents, particularly female adolescents who experience rapid physical and psychosocial changes. Adolescents with nutritional problems are more likely to feel dissatisfied withitheiribody shape, whichimay lead to unhealthy behaviors such as strict dieting or excessive eating to gain weight.

This research employedia quantitativeiapproachiwith aicross-sectionalidesign. Aitotal ofi169 femaleistudentsiwere selected using stratified random sampling. Body image data were collected using the Body Self Relation Questionnaire–Appearance Scale, while nutritional status was assessed using Body Mass Index for Age (BMI-for-Age) and Height for Age (HFA). Data were analyzed using the Spearman Rank correlation test. The results indicated that there was no significant relationship between nutritional status based on BMI-for-Age and body image, with a p-value of 0.329. Similarly, no significant relationship was found between Height-for-Age and body image among female adolescents, with a p-value of 0.892. Most respondents were aged 16–17 years, had a negative body image perception, normal BMI-for-Age nutritional status, and normal Height-for-Age category. These findings suggest that body image among female adolescents is not solely influenced by nutritional status but may also be affected by other psychosocial and environmental factors. Therefore, future research is recommended to apply a cohort study design and explore other determinants of body image, such as social media exposure, peer influence, and infectious diseases, to provide a more comprehensive understanding of factors affecting adolescent body image.

This article examines how meritocracy is institutionalized within the public administration systems of Indonesia and Singapore and how it affects public service quality. Using a descriptive–comparative library research design, the analysis focuses on four dimensions: bureaucratic structure, governing system and political influence, administrative reform and merit mechanisms, and implications for service delivery. The findings indicate that Indonesia’s bureaucracy remains highly hierarchical and decentralized, creating uneven institutional capacity and allowing electoral–political dynamics to influence appointments and rotations, which weakens consistent merit implementation. In contrast, Singapore operates a streamlined and centrally coordinated bureaucracy supported by high political stability, rigorous competency-based recruitment and promotion, transparent performance management, and competitive remuneration, enabling merit principles to be applied more consistently. These differences translate into more uniform and efficient public services in Singapore, while Indonesia continues to experience variability across regions and sectors. Strengthening merit enforcement, oversight, and professional culture is therefore crucial to improve the effectiveness and equity of public services in Indonesia.
