This chapter conceptualizes skincare as a critical site within global health capitalism shaped by digital platforms. Moving beyond aesthetics, skincare is analyzed as a biopolitical practice where health narratives, data extraction, and market logics converge. Using the lenses of surveillance capitalism, biopolitics, and platform governance, the chapter examines how AI skin diagnostics, digital tracking, influencer marketing, and e-commerce platforms transform skin into a source of data and economic value. Algorithmic personalization and biomedicalized discourses normalize continuous monitoring and consumption, positioning individuals as self-managers of skin health. The chapter highlights regulatory and access inequalities across regions and calls for more transparent, equitable, and evidence-based governance in the digital skincare economy.

Early marriage remains prevalent in several regions of Indonesia, particularly in Jember, which records the highest rate in East Java despite the legal age restrictions. This phenomenon is deeply rooted in family ideology, especially the mother’s role as a central figure shaping children’s perceptions. This study aims to reveal the mindset of mothers and adolescents through a syntactic analysis based on Systemic Functional Linguistics (SFL), focusing on the ideational, interpersonal, and textual metafunctions. Using a qualitative method, data were obtained from utterances collected through observations and elicitation interviews conducted in Madura language with responses in Indonesian. The data were analyzed using referential comparison and free interpretation methods. Findings indicate that mothers’ speech reproduces cultural, moral, and religious values concerning women’s roles, while adolescents’ language reflects conformity to those norms. Linguistic relations between them sustain early marriage as part of the established social value system, reflecting patriarchal ideology and power embedded in rural Javanese and Madurase culture. By using SFL theory, this research has succeeded in revealing that language structure is not neutral, but rather reflects the collective mindset of society which views early marriage as a moral and social obligation, not as a violation of individual rights.

This scoping review synthesizes evidence on the intergenerational digital divide and Indonesian older adults’ awareness of AI-generated images and videos. Methods employed were PRISMA-ScR, the researchers screened scholarly and grey sources (2017–2025). Data were charted on standard fields and coded to STAM and PMT/TTAT constructs. Twenty records met the criteria. Results cover evidence concentrated on synthetic media salience rather than task-based detection. Facilitating conditions and governance baselines recur as primary drivers, while social influence, especially group messaging pathways, shapes exposure and sharing. Self-efficacy appears in training notes, but measurement skews toward knowledge, not calibrated accuracy. Usefulness and effort expectancy are implicit in low-friction designs; anxiety is inferred from risk and inequality signals. Indonesian, urban elder samples are scarce; platform workflow specifics and calibration outcomes are limited. Conclusions of this research confirm that the literature affirms awareness of AI visuals yet reveals actionable gaps. In the Indonesian context, standardized detection tasks with confidence calibration, and explicit acceptance determinants have not yet been conducted comprehensively. We recommend senior-friendly micro-lessons deploying a see–pause–verify routine inside high-traffic channels, aligned with national digital literacy pillars and supported by lightweight monitoring and evaluation. Priorities include collecting calibrated detection data and testing in-app verification cues within everyday sharing flows to strengthen elder-centered visual literacy and resilience.

ABSTRACT Super‐intensive shrimp aquaculture generates effluents with elevated nitrogen species and suspended solids that exceed environmental discharge limits. In this study, a hydroxide‐activated Fe/C internal electrolysis (IE) system was developed for the treatment of super‐intensive pond wastewater. The novelty lies in the use of NaOH activation to suppress electrode passivation and sustain iron redox cycling without external energy input. Under near‐neutral conditions (pH 7–8.5), the system achieved up to 89.9% average removal of NO 2 − –N, NO 3 − –N, NH 3 –N, total suspended solids (TSS), and total dissolved solids (TDS), representing a 2–5‐fold improvement compared to conventional aeration‐based wastewater treatment plant (WWTP) performance. Electrode characterization (scanning electron microscope [SEM]–EDX, x‐ray diffractometer [XRD], x‐ray fluorescence [XRF]) confirmed dynamic formation of Fe 2 O 3 and Fe(OH) 3 phases, which functioned as in situ coagulants and catalytic redox mediators. Nitrogen removal proceeded via sequential nitrate reduction to nitrite and subsequent conversion to N 2 , coupled with adsorption and coagulation by iron hydroxide flocs. Hydroxide activation promoted a self‐regenerating passivation–corrosion cycle, ensuring sustained electrode activity. These findings demonstrate that hydroxide‐activated Fe/C IE offers a low‐cost, energy‐efficient, and scalable strategy for sustainable aquaculture wastewater management.

Science process skills are crucial in biology education and benefit from experiential, inquiry-based approaches. However, biology learning often remains abstract and lacks subject-specific media. This study investigated the effectiveness of STEM-based learning using biodegradable microgreen seed paper to enhance eleventh-grade students’ science process skills and learning responses in plant growth and development. Using a one-group pretest–posttest design (n = 36), students engaged in scientific inquiry, engineering-based design of seed paper, and technology-assisted observation. Science process skills were assessed via essays, and student responses via a Guttman-scale questionnaire. Data analysis with N-gain and the Wilcoxon test showed significant improvement in science process skills (pretest mean = 63.19, posttest mean = 89.03, N-gain = 0.71, Z = −5.248, p < 0.05) and very positive student responses (97%). These findings suggest STEM-based microgreen seed paper learning effectively enhances science process skills and engagement, supporting SDG 4 (Quality Education) and SDG 12 (Responsible Consumption and Production).

This study explores early childhood education (ECE) teachers’ perceptions of young children’s critical thinking skills using Peter A. Facione’s critical thinking framework. Employing a quantitative descriptive design, data were collected from 131 ECE teachers in Banten Province through a structured questionnaire. The analysis revealed that teachers demonstrated a relatively strong understanding of problem analysis but showed limited comprehension of other critical thinking components, including interpretation, analysis, inference, evaluation, explanation, and self-regulation. This gap potentially impairs their capacity to stimulate children’s reasoning, reflection, and conclusion-making skills. Furthermore, teachers were found to rely predominantly on factual questioning, with minimal emphasis on promoting analytical or evaluative thinking during classroom interactions. The findings underscore the urgent need for targeted professional development programs that equip teachers with effective questioning techniques and instructional strategies aimed at fostering higher-order thinking. Integrating critical thinking into the early childhood curriculum through play-based and inquiry-driven approaches holds promise in enhancing children’s cognitive flexibility, reflective thinking, and problem-solving abilities beyond mere factual recall.
