Long-term increases in blood pressure can trigger stroke. Therefore, stroke prevention behavior needs to be improved as an effort to prevent stroke in hypertension patients. The purpose of this study is to represent stroke prevention behavior carried out by hypertension patients. The research design used is quantitative descriptive with a cross-sectional approach. The study was conducted in the working area of ​​the Sooko Community Health Center with a population of hypertension patients, the number of samples was 52 respondents with a sampling technique using purposive sampling. The results showed that most of the respondents carried out stroke prevention behavior in the adequate category as many as 27 respondents (52%). Stroke prevention behavior in the sufficient category can be reflected in the respondents' efforts to control blood pressure, take antihypertensive drugs as recommended, limit consumption of foods high in salt and fat, do regular exercise, and have regular health checks, although not yet done consistently.</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Arum Dwi Ningsih, Rizky Meuthia Pratiwi, Lutfi Wahyuni, Binarti Dwi Wahyuningsih https://jsret.knpub.com/index.php/jrest/article/view/911 Strengthening the Character Education of Alpha Generation through a Mosque-Based Maghrib Mengaji Program: A Qualitative Study 2026-07-03T10:59:58+00:00 Mahathir Akbar akbarmahathir@gmail.com Didi Mustahdi mustahdididi@gmail.com Dudung Abdul Rohman semangatsukses94@gmail.com Sifa Syahidah syifa0920@gmail.com <p>The rapid development of digital technology has brought significant changes to the behavior and character formation of Generation Alpha, creating challenges for Islamic character education in both formal and non-formal educational settings. As a community-based Islamic educational institution, the mosque has a strategic role in strengthening children's character through religious habituation programs. This study aims to analyze the implementation of the Maghrib Mengaji Program, identify the character values developed, examine the role of the mosque in strengthening character education, and explore the supporting and inhibiting factors in implementing the program at Al-Hidayah Mosque, Gandawesi Village, Ligung District, Majalengka Regency. This research employed a qualitative approach using a case study design. Data were collected through observations, semi-structured interviews, and documentation involving mosque administrators, Qur'anic teachers (ustadz), parents, and program participants. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña, including data condensation, data display, and conclusion drawing. The findings reveal that the Maghrib Mengaji Program is implemented systematically through congregational Maghrib prayer, Qur'anic learning, tahsin, memorization of short surahs, Islamic moral instruction, and continuous religious habituation. The program successfully strengthens religious character, discipline, responsibility, honesty, independence, politeness, and social awareness among Generation Alpha. Its success is supported by collaboration among mosque administrators, teachers, parents, and the local community, while challenges include excessive digital device use, limited teaching personnel, and inconsistent participant attendance. This study concludes that the Maghrib Mengaji Program represents an effective mosque-based model of non-formal Islamic education for strengthening the character of Generation Alpha through the integration of Qur'anic learning, exemplary practices, religious habituation, and community participation.</p> <p> </p> 2026-07-10T00:00:00+00:00 Copyright (c) 2026 Mahathir Akbar, Didi Mustahdi, Dudung Abdul Rohman, Sifa Syahidah https://jsret.knpub.com/index.php/jrest/article/view/1171 Child Protection from Online Grooming in Indonesian Criminal Law 2026-06-28T09:56:33+00:00 Fadli Yasser Arafat Juanda fadliyasser@unsulbar.ac.id M Zaldy Zaldy@gmail.com <p>Online grooming of children has emerged as one of the most alarming manifestations of digital sexual exploitation, yet Indonesia's criminal law framework has been slow to address it coherently. This study examines whether four major Indonesian criminal law instruments, the Child Protection Act (Law No. 35 of 2014), the Electronic Information and Transactions Act (Law No. 19 of 2016), the Sexual Violence Crimes Act (Law No. 12 of 2022), and the National Penal Code (Law No. 1 of 2023), are adequate to criminalize and prosecute online grooming behavior against children. Employing a normative legal research design with statute and conceptual approaches, this study analyzes primary legal materials and international instruments to identify normative gaps. The findings reveal three critical deficiencies: the absence of a statutory definition of grooming, incomplete coverage of preparatory acts as independent criminal offenses, and inadequate cross-sectoral coordination mechanisms. While the Sexual Violence Crimes Act and the National Penal Code represent meaningful legislative progress, neither fully incorporates online grooming as a distinct, standalone criminal offense. This study recommends targeted legislative amendments and enhanced implementation protocols to align Indonesia's criminal law framework with its obligations under the Convention on the Rights of the Child and international child protection standards.</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Fadli Juanda, M Zaldy https://jsret.knpub.com/index.php/jrest/article/view/1169 Trends in Youth Participation and Leadership in Indonesia: Analysis of Youth Development Index data 2015-2023 2026-07-03T12:28:57+00:00 Wiwin Rosmawati rosmawatiwiwin0210@gmail.com Muhammad Syah Fibrika Ramadhan Muhammad.syah@unsoed.ac.id <p>This study analyzes youth participation and leadership trends in Indonesia (2015–2023) using Youth Development Index (IPP) data from the Ministry of Youth and Sports. A quantitative, descriptive-analytical time-series approach was applied across 34 provinces. The results show youth social participation stabilized at 81.36% (2015–2020) but dropped significantly to 70.49% (2021–2022) due to the COVID-19 pandemic, before recovering to 71.44% in 2023. Conversely, organizational activity and meeting attendance remained stable. Striking regional disparities emerged: West Nusa Tenggara recorded the highest rate (87.31%), while DKI Jakarta recorded the lowest (38.3%). Overall, the Participation and Leadership Indicator Index stagnated at 46.67% and fell to 43.33%, reflecting suboptimal performance. The study concludes that youth development requires differentiated policy strategies based on regional characteristics, strengthening organizational ecosystems, leveraging digital transformation, and further research for effective policy interventions.</p> 2026-07-10T00:00:00+00:00 Copyright (c) 2026 Wiwin Rosmawati, Muhammad Syah Fibrika Ramadhan https://jsret.knpub.com/index.php/jrest/article/view/1184 The Impact of Democratic Parenting on the Language Development of Children Aged 3–5 Years 2026-07-03T12:31:20+00:00 Nurhuda Akbar nurhudakbar610@gmail.com Nunuk Nurhayati nunuknurhayati79@gmail.com <p>The first five years constitute the "golden years" of an individual's life. This peak period of development requires appropriate stimulation to achieve optimal growth. It is also a time when intelligence, skills, language abilities, and social skills are formed. A child's growth and development are influenced by various factors, including genetics and environmental elements (biological, physical, and psychosocial factors, as well as family dynamics and cultural customs). Parenting styles significantly influence child development, particularly regarding communication. Parenting practices—such as emotional attachment, verbal interaction, and the structuring of the communication environment—play a crucial role in either supporting or hindering a child's speech development. Parenting styles that lack communication or interaction can lead to difficulties in a child's speech skill acquisition. Every child grows in a unique way. Child development encompasses four domains: gross motor skills, fine motor skills, personal-social skills, and language. This study employed a cross-sectional research design with a sample size of 25 participants. The independent variable was parenting style, and the dependent variable was the child's language development. The Spearman’s rho test results yielded a value of p = 0.05 &lt; α = 0.018, indicating a relationship between parenting style and language development in children aged 3–5 years; specifically, children raised under a democratic parenting style demonstrated superior verbal abilities compared to those raised under authoritarian or permissive styles. Consequently, the roles of both mother and father in child-rearing have a significant impact on language development. Mothers, who typically interact more frequently with their children at home, play a key role in providing language stimulation.</p> 2026-07-10T00:00:00+00:00 Copyright (c) 2026 Nurhuda Akbar, Nunuk Nurhayati https://jsret.knpub.com/index.php/jrest/article/view/1165 Role Structure and Rhytmic Nomenclature of Indang Music in Nagari Tandikek 2026-06-28T09:53:29+00:00 Hasanul Rizki Febrian aditotonk06@gmail.com Aditya Dwi Ananda Firdaus aditotonk06@gmail.com Asril aditotonk06@gmail.com <p>This study aims to comprehensively describe the internal role structure of performers and the local nomenclature of rhythmic patterns produced by the <em>rapai</em> instrument in the Indang traditional performance within Nagari Tandikek. Utilizing a descriptive qualitative approach with an ethnomusicological perspective, data were gathered through in-depth interviews with a maestro and <em>tukang dikie</em> of Indang, supplemented by direct field observations of drumming techniques. The findings reveal that Indang Tandikek possesses a highly specific and rigid role structure consisting of <em>tukang dikie</em>, <em>tukang karang</em>, <em>tukang darak</em>, <em>tukang lalu</em>, <em>tukang apik</em>, <em>tukang aliah</em>, and <em>tukang panuruikan</em>. Each role fulfills a distinct musical function crucial to maintaining performance continuity. Regarding organology and drumming techniques, the study identifies distinct local interlocking variations: <em>darak panjang</em> serves exclusively as the opening pattern, while the <em>darak pendek</em> group—comprising <em>darak katereang</em>, <em>darak patiang jongkek</em>, and <em>darak tujuah</em>—is played during vocal (<em>dendang</em>) pauses. Furthermore, the overall dynamics and tempo esclations are governed collectively through intuition (<em>feeling</em>) and technical mastery of the primary players rather than strict mathematical counts. This study concludes that the rhythmic complexity of Indang Tandikek functions not only as a visual aesthetic regulator but also as a preservation mechanism for social rhythms through a transmission system rooted in the <em>kulipah</em> (school lineage).</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Hasanul Rizki Febrian, Aditya Dwi Ananda Firdaus, Asril https://jsret.knpub.com/index.php/jrest/article/view/1179 Strengthening Disaster Mitigation through Risk Communication in the Palm Oil Industry Occupational Safety and Health System: A Narrative Literature Review 2026-06-28T09:36:16+00:00 Dewi Nuraliah dewinuraliah.baili@gmail.com Rezki Rahmawati rezki.rahmawati@unsulbar.ac.id Nurfadilah Nasiruddin nurfadilah.nasiruddin@unsulbar.ac.id Moh.

This study aims to analyze the role of risk communication in strengthening disaster mitigation through the Occupational Safety and Health system in the palm oil industry. The research uses a qualitative approach with a narrative literature review method. Data were obtained through literature searches on ScienceDirect, Google Scholar, SpringerLink, and DOAJ, then analyzed thematically through synthesis and interpretation processes. The results of the study show that risk communication plays a role in shaping risk perceptions, strengthening safety cultures, improving organizational preparedness, and supporting coordination in disaster mitigation. Risk communication also connects the technical aspects of the K3 system with the behavioral and governance aspects of the organization.</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Dewi Nuraliah, Rezki Rahmawati, Nurfadilah Nasiruddin, Moh.

Employing a qualitative case study design, data were collected through semi-structured interviews with school principals, teachers, curriculum coordinators, and parents, complemented by classroom observations and document analysis. Participants were selected through purposive sampling based on their direct involvement in Foundation Phase curriculum enactment. Data were analysed using reflexive thematic analysis following Braun and Clarke's six-step procedure, with trustworthiness established through triangulation, member checking, peer debriefing, and thick description. Four major themes emerged from the analysis: policy communication and stakeholder understanding, classroom practices supporting collaboration, development of children's independence, and challenges and supporting factors in policy implementation. Findings revealed that effective policy communication, facilitated through iterative professional dialogue and principal leadership, progressively deepened teachers' conceptual understanding of Foundation Phase principles. Collaborative classroom practices—including cooperative play, joint problem-solving, and shared group responsibilities—produced observable improvements in children's peer interaction and cooperative behaviours. Children's independence developed along a scaffolded pedagogical pathway from teacher-directed support toward increasingly autonomous self-directed engagement, though individual developmental variability was consistently noted. Persistent implementation challenges included administrative documentation burden, variation in teacher readiness, and limited access to sustained professional development. The study contributes to educational policy implementation literature by demonstrating an empirical pathway linking policy communication processes, through classroom pedagogical practices, to observable child developmental outcomes, thereby positioning child competency development as a meaningful indicator of policy implementation effectiveness.</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Erna Widiastuti, Tri Rijanto, Muji Sri Prastiwi https://jsret.knpub.com/index.php/jrest/article/view/1172 Profile and History of the Petu Dondo Dance as an Intangible Cultural Heritage in Tolitoli 2026-07-03T12:33:22+00:00 Windi windiindi001@gmail.com Haliadi windiindi001@gmail.com Suyuti suyuti@untad.ac.id Misnah misnah@untad.ac.id <p>The results of this study aim to examine the history of dance, identify the profiles of creators and dancers, and analyze the process of submitting the petu dondo dance as an intangible cultural heritage. The method used is descriptive qualitative. The results of this study indicate that: the history of the petu dondo dance was created by two local artists, namely H. Simon Ismail Tonggolipu and Siti Rahmatia A, Md. Kep in 1992 to be performed at the cultural week in the framework of the anniversary of the Tolitoli Regency. The petu dondo dance as a local cultural heritage that has important historical and cultural values for the Dondo community but has not been widely documented academically or administratively and has not been registered as an Intangible Cultural Heritage (WBTB). In conclusion, the petu dondo dance is a traditional art work originating from Tinabogan Village, Dondo District, Tolitoli Regency, which was created in 1992. The petu dondo dance was created to be performed at the cultural week in the framework of the anniversary of the region and has not been designated as an Intangible Cultural Heritage (WBTB).</p> 2026-07-10T00:00:00+00:00 Copyright (c) 2026 Windi, Haliadi, Suyuti, Misnah https://jsret.knpub.com/index.php/jrest/article/view/1170 Generalized Anxiety Disorder with Somatic Symptom Presentation and Social Avoidance: A Case Report 2026-06-26T03:01:53+00:00 Alfiona Syafira Putri Arinda anputsya.76@gmail.com Era Catur Prasetya asparinda14@gmail.com <p>Generalized Anxiety Disorder (GAD) is a psychiatric disorder that frequently presents with somatic complaints, which can lead to delayed diagnosis. This case report aims to describe the clinical manifestations, diagnostic process, and therapeutic response in a patient with GAD dominated by somatic symptoms.&nbsp; Case: A 63-year-old female patient presented with initial complaints of acid reflux sensation and epigastric pain since 2022. Medical examinations showed results within normal limits. The complaints progressed to palpitations, excessive anxiety, particularly in social situations, avoidance behavior, and sleep disturbances. The patient experienced a decline in social functioning, which subsequently improved after receiving pharmacological therapy and psychotherapy.&nbsp; Somatic symptoms in GAD are associated with autonomic nervous system activation and the brain–gut axis interaction. The diagnosis was established based on DSM-5-TR criteria, considering biopsychosocial aspects. Management using a combination of Selective Serotonin Reuptake Inhibitors (SSRIs) and Cognitive Behavioral Therapy (CBT) proved effective in improving the patient's symptoms and functioning.&nbsp;&nbsp;</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Alfiona Syafira Putri Arinda, Era Catur Prasetya https://jsret.knpub.com/index.php/jrest/article/view/1168 Increasing the Capacity of Midwives in Managing Diastasis Recti Abdominalis in Postpartum Care Based on Evidence-Based Practice 2026-06-28T09:30:26+00:00 Lasiyati Yuswo Yani yuswoyani@gmail.com <p>Diastasis Recti Abdominalis (DRA) is a postpartum musculoskeletal problem that is often overlooked, even though it poses a risk of reducing the quality of life of postpartum mothers. Midwives as the frontline of postpartum care need to have the capacity to detect and provide safe initial management. This Community Service (PKM) activity aims to improve midwives' knowledge and clinical skills in DRA management through structured Postnatal Yoga technique training. The service partner is the Indonesian Midwives Association (IBI) Branch X which involves 30 independent practicing midwives. The implementation method uses interactive lectures, manual detection demonstrations, and postpartum yoga movement modification workshops. Evaluation of the activity was carried out using pre-test and post-test knowledge instruments. The results of the activity showed a significant increase in the average midwives' knowledge score from 58.3 (poor category) to 87.5 (good category) after the training (p &lt; 0.001). All participants (100%) were also able to demonstrate DRA screening and guide functional yoga movements correctly and safely. This capacity building is expected to optimize the quality of comprehensive postpartum care at the primary care level.</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Lasiyati Yuswo Yani https://jsret.knpub.com/index.php/jrest/article/view/1180 Integrating Local Wisdom into Twenty-First Century Curriculum Transformation: Evidence from Indonesian Schools 2026-06-29T04:09:58+00:00 Sigid Budianto sigidbudianto39@gmail.com Ahmad Ali Darmawan alidarmawan313@gmail.com Nanda Hasnan Fardany nandahasnan6@gmail.com Anip Dwi Saputro anipdwisaputro@gmail.com <p>This qualitative case study examines how local wisdom has been integrated into curriculum transformation at SMK Negeri 2 Ponorogo, a vocational secondary school in East Java, Indonesia. Using semi-structured interviews (n=25), classroom observations, curriculum document analysis, and field notes, the study investigated mechanisms through which vocational schools pursue culturally responsive education while maintaining alignment with national standards. Five major themes emerged from thematic analysis: (1) local wisdom appears as contextual learning resources embedded within subjects rather than as independent curriculum content; (2) teachers actively interpret national curriculum objectives through professional judgment and contextual knowledge, producing varied curriculum enactment across programs; (3) students associate local wisdom integration with authentic learning experiences through community-based projects and apprenticeships with traditional practitioners, though without reported effects on academic achievement; (4) curriculum transformation occurs through continuous negotiation between national standards, industry competencies, assessment requirements, and cultural preservation rather than through curriculum replacement; and (5) school leadership facilitates curriculum innovation through distributed decision-making and collaborative support rather than directive mandates. The study contributes to curriculum transformation literature by positioning local wisdom as a contextual mediating resource through which national competencies can be developed, rather than as cultural content competing with standardized curricula. Findings suggest that sustainable vocational curriculum transformation in centralized education systems may occur more effectively through facilitated teacher enactment and professional agency than through top-down policy mandates. The research provides empirical evidence from Southeast Asian vocational education, a context underrepresented in international curriculum scholarship. Results may inform curriculum developers, vocational school leaders, teachers, and educational policymakers designing culturally responsive curriculum initiatives within standardized governance structures. Future research employing comparative case studies across different vocational disciplines and regions could strengthen understanding of how schools navigate tensions between standardization and cultural responsiveness.</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Sigid Budianto, Ahmad Ali Darmawan, Nanda Hasnan Fardany , Anip Dwi Saputro https://jsret.knpub.com/index.php/jrest/article/view/1164 Design of a Pyrolysis Reactor for Polystyrene Plastic Waste and Numerical Analysis of Temperature and Thermal Stress Distribution Using Ansys 2026-06-28T09:51:12+00:00 Ali Syamsuddin 1422200062@surel.untag-sby.ac.id Moh Mufti mufti@untag-sby.ac.id <p>The difficult to degrade polystyrene (PS) waste requires efficient pyrolysis technology to be converted into styrene fuel through a 450°C thermal process. This study designed a batch reactor with a conical cylinder (with a diameter of 30 cm, a height of 30 cm, a diameter of 5.08 cm at the base of the cone, and a height of 15 cm, with a capacity of 3 kg of polystyrene) using Ansys for steady-state thermal-structural analysis to determine the best material based on the highest safety factor. The best material was SS 316, with a heating power of 1404 W, which produced the highest temperature distribution of 564,42 ℃ at the surface near the burner. Meanwhile, the internal surface of the reactor had reached 542,88 ℃, which could degrade the polystyrene pyrolysis temperature at an operating temperature of 450 ℃, with an average temperature of 144,4 ℃. The total heat flux on this material is 0.096078 W/mm² in the area of the connection. The safety factor for the reactor with SS 316 material is 1.44 at the maximum Von Misses stress due to the actual thermal gradient of 200,32 MPa.</p> 2026-07-03T00:00:00+00:00 Copyright (c) 2026 Ali Syamsuddin, Moh Mufti
