Abstract

Screen Time offers potential benefits and risks to child development, particularly without parental supervision. Although parents recognize the importance of managing screen use, implementation at home remains inconsistent. This study designed an educational campaign using the Design Thinking method to understand parental needs and develop appropriate communication solutions. Data were collected through interviews, observations of stakeholders and existing campaign media, and questionnaires distributed to parents of children aged 3–5 years. The findings were analyzed to identify key problems and develop creative campaign concepts, which were translated into visual media prototypes for effectiveness evaluation. Results indicate that parents need campaign messages that are engaging, relevant to daily life, and easy to implement. YouTube, TikTok, and Instagram were identified as effective visual communication platforms. The campaign centers on “Healthy Screen Time Awareness Education for Children,” emphasizing that screen use is not inherently negative and can provide benefits when managed appropriately with active parental supervision. Through educational and empathetic communication, the campaign aims to increase parental awareness and encourage more consistent implementation of healthy Screen Time practices. Designed as an ongoing educational initiative, it supports responsible digital parenting and healthier screen habits among children aged 3–5 years.

Abstract

The development of online gaming platforms has encouraged the emergence of virtual communities that facilitate intensive social interaction. One of the most widely used platforms is Roblox, which functions not only as a gaming medium but also as a space for communication and interpersonal relationship building. This study aims to examine the influence of virtual interaction on the Roblox platform toward self-confidence in interpersonal communication among members of the TGRC community. The study is grounded in Computer-Mediated Communication (CMC), Social Penetration Theory, and Social Cognitive Theory to explain the process of virtual communication and the development of self-confidence. This research employed a quantitative explanatory approach by distributing Likert-scale questionnaires to 136 TGRC community members selected through purposive sampling. Data were analyzed using IBM SPSS Statistics Version 26, including validity and reliability tests, classical assumption tests, simple linear regression analysis, F-test, t-test, and coefficient of determination. The findings indicate that virtual interaction on the Roblox platform has a positive and significant effect on self-confidence in interpersonal communication. Higher levels of virtual interaction are associated with greater self-confidence in communicating with others. These findings suggest that virtual interaction can serve as an effective medium for enhancing individuals' interpersonal communication skills within online communities.

Abstract

The growth of hyperlocal media in Indonesia has made local information more accessible to communities, yet viral content produced by these outlets is frequently republished by mainstream media with varying forms of attribution. This study analyzes how the appropriation of hyperlocal media content by mainstream media is represented in news texts, and how asymmetric power relations between the two are reflected in those texts. Using a critical paradigm and a qualitative approach, the study applies critical qualitative content analysis supported by Robert Entman's framing analysis, and interprets the findings through Vincent Mosco's Political Economy of Media. The data consist of six texts from three case pairs published between October and December 2025: @infobekasi-Viva.co.id, Metrokendari.com-Tribunnews.com, and @medsosaceh-Pojoksatu.id. The findings show that appropriation takes the form of reproducing previously published information, less prominent source attribution, changes in presentation structure, content modification, and a shift or simplification of framing: toward virality in the first pair, toward dramatization in the second, and toward information compression with a relatively similar frame in the third. The results indicate asymmetric power relations in which hyperlocal media act as initial information producers, while mainstream media hold greater distribution capacity and institutional legitimacy. Through the lens of commodification, spatialization, and structuration, the practice potentially strengthens the position of mainstream media in the cases analyzed. The findings are limited to three case pairs and are not intended to be generalized to the entire Indonesian digital media landscape.

Abstract

The improper use of artificial intelligence to create deepfake pornography raises questions about the legal basis of criminal liability and the restoration of victims’ rights. This paper attempts to examine the legal classification of synthetic pornography, the legal position of restitution, and ways to protect the victims in the criminal prosecution of such cases without resorting to the Law on Sexual Violence Crimes. A normative-doctrinal legal research method was used based on statutory, conceptual, and case approaches. The legal materials were studied in a qualitative manner with the descriptive-analytical method of research. Criminal law, the law on restitution, open-access scientific articles, and the 2026 case of the Semarang District Court were considered as research materials. As can be seen, the criminal offense element should be separated from the determination of the right to restitution. Victims' rights might be considered with the help of the Law on Sexual Violence Crimes, Witness and Victim Protection Law, and Supreme Court Regulation No. 1 of 2022, depending on their legal conditions. Based on open sources, it is impossible to tell whether the question of restitution was considered in the decision of the court.

Abstract

Postpartum depression is a maternal mental health problem that can negatively affect mothers, infants, and families. Adequate knowledge and positive attitudes toward postpartum depression prevention are important components of maternal mental health promotion during pregnancy. This study aimed to determine the effect of social media content-based education on the knowledge and attitudes of pregnant women regarding postpartum depression prevention at TPMB Rafika Bojonggede in 2026. This study used a pre-experimental design with a one-group pretest-posttest approach. The sample consisted of 194 second-trimester pregnant women selected using purposive sampling. Data were collected using knowledge and attitude questionnaires administered before and after the educational intervention. Data were analyzed using the Wilcoxon Signed-Rank Test with a significance level of 0.05. The results showed an increase in the mean knowledge score from 49.04 before the intervention to 56.02 after the intervention. The mean attitude score also increased from 40.01 to 43.94. The Wilcoxon test showed a p-value of p<0.001 for both knowledge and attitude, indicating a significant difference between pretest and posttest scores. Education delivered through social media content was accompanied by improvements in pregnant women's knowledge and attitudes toward postpartum depression prevention. Social media-based education may be utilized as a promotive and preventive strategy in maternal healthcare services.

Abstract

This study aims to examine and analyze the use of concrete media in the student environment to understand the basic concepts of surface area and volume of a cone through the Realistic Mathematics Education (RME) approach among ninth-grade students at SMP Negeri 1 Batang Kuis. Learning was designed to assist students in discovering mathematical formulas and relationships independently through direct experience with concrete media, such as cone nets, real-world conical objects (birthday hats, ice cream cones, and funnels), and RME-based Student Worksheets (LKPD). This research employs a descriptive quantitative-qualitative method. The subjects were 25 ninth-grade students of SMP Negeri 1 Batang Kuis. Data were collected via written individual assessments to measure conceptual understanding and group LKPD evaluations to assess the process of concept discovery. Data were analyzed descriptively based on individual and group scores. The results indicated an average individual assessment score of 42.00, with only 3 students (12.00%) achieving mastery (score ≥ 70) and 22 students (88.00%) scoring below 70. Conversely, the group-based LKPD evaluations yielded a high average score of 86.00, with all groups (100%) exceeding the mastery threshold. These findings demonstrate that concrete media integrated with RME effectively fosters collaborative learning and exploratory concept discovery in group settings. However, gradual guidance is essential to help students transition from concrete understanding to formal individual mathematical problem-solving.

Abstract

Mosquitoes are insects that can disturb human activities and contribute to the spread of various diseases. One way to reduce the risk of mosquito bites is to use repellents. Lemongrass leaves (Cymbopogon citratus (DC.) Stapf) contain bioactive compounds and essential oils that have the potential to be developed as natural mosquito repellents. This study aimed to identify the bioactive compounds and analyze the mosquito repellent activity of lemongrass leaves based on previous research. The method used was a Systematic Literature Review (SLR), with articles searched through Google Scholar, PubMed, ScienceDirect, the Directory of Open Access Journals (DOAJ), and Garuda. The reviewed articles were limited to publications from 2021 to 2026 and selected based on their relevance to the research topic. The initial review of eight articles indicated that lemongrass leaf extracts exhibited repellent activity against several mosquito species under specific testing conditions. One study reported a repellency rate of 89.5% at a concentration of 25%, while another found that cream and emulgel formulations containing 2% extract provided more than 80% repellency. Lemongrass essential oil also showed potential for development into aromatherapy candles as mosquito repellent products. Its effectiveness was influenced by extract concentration, solvent type, formulation, and mosquito species tested. In conclusion, lemongrass leaves have potential as a natural mosquito repellent; however, further research on their effectiveness, safety, and duration of protection is still needed.

Abstract

Alzheimer's disease is a progressive neurodegenerative disorder in which cholinergic decline is managed mainly with acetylcholinesterase (AChE) inhibitors, yet the available drugs are limited by adverse effects and modest benefit. Natural products are therefore explored as alternative sources of inhibitors. This study aimed to systematically review the evidence on bioactive compounds from natural sources as AChE inhibitors for Alzheimer's therapy. Twenty scientific articles published between 2020 and 2026 were reviewed qualitatively, consisting of nine primary studies (molecular docking, in vitro enzyme assays, and combined approaches) and eleven review articles. Data on the tested materials, methods, and main findings were extracted and compared across studies. The primary studies showed that several compounds, such as chrysophanic acid, epigallocatechin gallate, gedunin, and astragalin, had favorable docking scores against AChE, whereas crude plant extracts displayed only moderate inhibition in vitro compared with the reference inhibitor. The reviews indicated that alkaloids, flavonoids, terpenoids, and marine metabolites are the main classes with anticholinesterase potential, frequently accompanied by antioxidant and anti-inflammatory effects. However, most of the evidence remains computational or preclinical, and pharmacokinetic and toxicity data are scarce. Natural bioactive compounds are promising AChE inhibitor candidates, but they require further experimental validation and preclinical development.
