Abstract

Background: Temper tantrums often occur in early childhood and can disrupt learning and social interaction in kindergarten settings. Specific background: At one kindergarten in Kaliorang District, repeated tantrums among students led teachers to develop structured strategies. Knowledge gap: Although tantrums are common, there is limited research exploring practical classroom-based programs designed by teachers themselves in Indonesian early childhood contexts. Aims: This study examines the structure, application, and challenges of the “Gentle Heart” program designed to manage temper tantrums in kindergarten. Results: Using a qualitative case study involving two experienced teachers over three months, findings show that the program reduces tantrum intensity and frequency through a calm–reflect–guide approach. Teachers allow emotional expression, wait for children to regain calm, and then engage them in reflective dialogue. Novelty: The study highlights a locally developed, teacher-led program that integrates emotional regulation strategies without external psychological intervention. Implications: The program offers a practical framework for early childhood teachers to manage tantrums in class, emphasizing the need for teacher assistants to sustain learning during tantrum episodes. Highlight Teachers apply structured emotional regulation steps to manage tantrums. The program shows reduced frequency and intensity of temper tantrums. Staffing support is essential for maintaining classroom learning flow. Keyword Temper Tantrum, Early Childhood Education, Emotional Regulation, Classroom Program, Teacher Strategies

Abstract

A 15-year-old female patient presented with severe anterior crowding in both the maxillary and mandibular arches. The patient expressed concern regarding facial esthetics and a convex profile and had a history of retained root fragments in the mandibular right and left first molars, as well as persistence of primary teeth in the regions of teeth 55 and 65. A midline deviation was also observed. Clinical examination revealed a Class I molar relationship, while cephalometric analysis showed a skeletal Class II tendency. The upper right and left first premolars were extracted to relieve anterior crowding. The space resulting from the loss of the mandibular first molars was utilized to align the crowded lower teeth. This extraction strategy was employed to improve the vertical dimension and enhance the patient's facial profile. In conclusion, extraction of the maxillary first premolars can be considered as one of the treatment options for managing dental crowding. Extraction-based treatment may help achieve an esthetically pleasing and functionally stable occlusion. Highlights: Severe anterior crowding managed with upper first premolar extractions. Mandibular molar space utilized for alignment and vertical control. Extraction approach improved facial profile and occlusal stability. Keywords: Dental Crowding, Premolar Extraction, Skeletal Class II, Facial Esthetics, Orthodontic Treatment

Abstract

To power low-power household appliances, this study investigates the harvesting of RF signal energy using a Villard–Dickson rectifier circuit and a 470 MHz dipole antenna. The RF signal from the handy talkie is converted into DC voltage when measured from a distance of 5 to 25 cm. The voltage drops from 7.7V to 1.5V, and the current drops from 30mA to 10mA. A relationship showing the voltage and current decreasing almost inversely with distance was found thru logarithmic regression data analysis. A high coefficient of determination indicates compatibility with free-space propagation theory. At a distance of 5 cm, the highest RF-to-DC conversion efficiency reached 18.3%. The resulting regression model allows for performance prediction at distances beyond testing and serves as a practical guide for building wireless power transmission systems and low-power IoT applications. Additionally, this model also serves as a scientific reference for research and dissertations in the field of RF energy harvesting. Highlights: RF-to-DC conversion achieved up to 18.3% efficiency at 5 cm. Voltage and current decrease inversely with distance, supported by logarithmic regression. Regression model enables prediction and application in low-power IoT systems. Keywords: regresi logaritmik, rectifier Villard-Dickson, antenna dipole

Abstract

Dental caries is one of the most common health issues among young children, especially in developing countries like Indonesia. This study aims to analyze the relationship between toothbrushing frequency and the prevalence of dental caries in children aged 3–5 years at TK Aisyiyah Kemantren Tulangan, Sidoarjo. A quantitative, cross-sectional design was used with a total of 38 child respondents. Data were collected through questionnaires given to parents, addressing children's toothbrushing habits and caries incidence. Results showed that 5-year-old children had a higher prevalence of caries (76.47%) compared to those aged 3 and 4. A total of 14 children (36.85%) experienced caries, while 24 children (63.15%) did not. Children who brushed their teeth twice a day had a lower caries prevalence (30%) than those who brushed once a day (70%). The study also highlighted the role of parental supervision in toothbrushing habits and its association with reduced caries incidence. Additionally, frequent consumption of sugary foods was identified as a contributing factor. In conclusion, a higher frequency of toothbrushing is associated with a lower prevalence of dental caries. Oral health education involving parents and a holistic approach to oral hygiene are crucial in preventing dental caries in children. Ongoing education programs at both school and home environments are necessary to promote proper oral hygiene behaviors from an early age. Highlights: Caries prevalence highest in 5-year-olds (76.47%). Twice-daily brushing linked to lower caries (30% vs 70%). Parental supervision and diet strongly influence caries risk. Keywords: toothbrushing frequency, dental caries, early childhood, oral hygiene, parental involvement

Abstract

General Background: Congenital heart disease (CHD) is a common structural or functional abnormality of the heart and great vessels that increases the risk of infective endocarditis, especially in pediatric patients. Specific Background: Children with complex defects such as subaortic Ventricular Septal Defect (VSD) accompanied by Atrial Septal Defect (ASD) and pulmonary hypertension are particularly vulnerable to oral infections that can lead to systemic complications. Knowledge Gap: Despite the recognized link between oral health and CHD, comprehensive protocols for dental “mouth preparation” under general anesthesia to minimize bacteremia and endocarditis risk before cardiac surgery remain limited. Aims: This case report describes a multidisciplinary approach to full-mouth preparation in a 4.5-year-old boy with VSD subaortic, ASD, and severe pulmonary hypertension, focusing on infection elimination, anesthesia management, and prophylactic strategies. Results: Treatment included restorations with Glass Ionomer Cement for reversible pulpitis, multiple extractions of necrotic teeth under general anesthesia, preoperative laboratory and radiological screening, American Society of Anesthesiologists assessment, and antibiotic prophylaxis with intravenous ampicillin followed by oral amoxicillin. Postoperative recovery was uneventful, with stable vital signs and satisfactory wound healing after one week. Novelty: This report highlights the integrated collaboration of pediatric dentistry, cardiology, and anesthesiology to ensure airway control, hemodynamic stability, and asepsis during extensive dental procedures in high-risk CHD patients. Implications: The findings underscore the importance of rigorous preoperative dental management and continuous preventive care—including parental education, low-sugar diet counseling, and regular dental visits—to reduce long-term risks of caries recurrence and infective endocarditis in children with congenital heart defects. Highlights: Comprehensive dental preparation prevents infective endocarditis risk. Multidisciplinary approach ensures safe anesthesia and hemodynamic stability. Ongoing preventive care reduces caries recurrence and systemic infection. Keywords: congenital heart disease, ventricular septal defect, atrial septal defect, dental management, general anesthesia

Abstract

Background: Safe and comfortable road pavement is a fundamental requirement, yet most designs rely on empirical methods that limit the ability to analyze detailed structural behavior. Specific Background: Analytical methods allow comprehensive evaluation of pavement layer strength, enabling faster and more precise calculations. Knowledge Gap: Limited studies have applied Bisar 3.0 guided by the Nottingham Design Method to calculate strain and service life in pavements using CTB (Concrete Treated Base) and Class B aggregate layers. Aim: This study applies the Bisar 3.0 program to determine road service life under fatigue cracking and permanent deformation criteria. Results: Calculations show analytical methods predict a longer service life (~±20 years) than empirical methods. Higher foundation stiffness and low average daily traffic reduce service life, and fatigue cracking criteria indicate a longer lifespan than permanent deformation. Novelty: Integration of Bisar 3.0 with Nottingham Design Method for precise service life estimation provides a detailed analytical approach rarely applied in road pavement studies. Implications: Findings support engineers in optimizing pavement design, selecting appropriate layer materials, and predicting long-term road performance more accurately. Highlights: Analytical design predicts longer road service life than empirical methods Fatigue cracking lifespan exceeds permanent deformation lifespan Bisar 3.0 enables rapid and precise calculation of pavement layer strains Keywords: Road Pavement, Analytical Method, Bisar 3.0, Nottingham Design Method, Service Life

Abstract

Background: Islamic education has long served as the foundation for shaping character and civilization, but institutional quality often lags behind rapid quantitative growth. Specific Background: Monitoring and evaluation (M&E) are frequently treated as administrative tools, detached from the spiritual values inherent in Islamic education. Knowledge Gap: Few studies have integrated modern management approaches with Islamic ethical principles to build a comprehensive conceptual framework for M&E in Islamic educational settings. Aim: This study explores a value-based M&E model in Madrasah Aliyah Diponegoro Yogyakarta, examining its role in institutional governance. Results: The findings show that M&E functions as a reflective and participatory mechanism that aligns modern quality management with Islamic ethics, strengthens moral identity, and supports sustainable governance. Novelty: This research proposes a synthesized model that bridges technical evaluation methods and spiritual values, positioning M&E as a strategic governance tool rather than a bureaucratic requirement. Implications: The model offers theoretical and practical contributions for policymakers and Islamic educational institutions aiming to establish value-integrated, participatory, and sustainable governance systems. Highlight Value-based monitoring and evaluation integrates modern management and Islamic ethics. Participatory approaches strengthen institutional identity and governance sustainability. The model provides a conceptual and practical reference for Islamic education reform. Keywords Monitoring And Evaluation, Islamic Education Management, Quality Management, Spiritual Values, Madrasah
