Abstract

Create an Internet of Things-based Air Conditioner operating system to make it easier to operate the AC. This research examines whether the system designed can transmit IR Code via IR Transmitter to AC if the device is placed at different distances. The steps to make it happen are to follow the stages of the prototyping method, which consist of gathering requirements, developing prototypes, and testing prototypes. The hardware circuit built consists of the Node MCU ESP8266, DHT 11 sensor, Infra-Red, software consisting of Arduino IDE, and blynk. By placing the NodeMCU ESP 8266 in positions with different distances, the tool can send IR Code data via the IR Transmitter to the AC, buttons on the blynk application have been made and can work according to their functions. The test was carried out with 4 different location positions, namely position 1 with a distance of 1 meter, position 2 with a distance of 3 meters, position 3 with a distance of 2 meters, and position 4 with a distance of 4 meters. From 4 test location positions with sufficient category signals to very good categories, microcontrollers can be connected to the blynk application on smartphone users. The Blynk application can function according to the commands made, the IR code can be sent through the IR transmitter to the air conditioner (AC). The DHT 11 sensor successfully measures the temperature and humidity of the air. Hopefully, in the future, the development of this tool into a multi-controller capable control not only AC but also other electronic devices.

Abstract

Childhood nutrition is essential for optimum growth and cognitive development, particularly in populations with a significant incidence of stunting.  This research used a longitudinal cohort design to evaluate the effects of nutritional treatments on children's growth and cognitive development.  A quasi-experimental design was used to compare children who underwent structured nutrition treatments—micronutrient supplementation, dietary variety enhancement, and maternal nutrition education—with those who did not receive the interventions.  A total of 128 children, aged 6 months to 6 years, were recruited using stratified random selection and observed at various time intervals.  The study findings indicated a significant reduction in stunting rates within the intervention group (from 35% to 20%) in contrast to the control group, which saw just a marginal decline (to 32%). Cognitive assessments using the Bayley Scales of Infant Development (BSID) and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) indicated superior results in the intervention group (p < 0.05).  Socioeconomic variables, notably maternal education and family income, impact the intervention's efficacy, highlighting the need for a comprehensive strategy that merges nutritional assistance with educational initiatives for mothers.  This research underscores the need of comprehensive, evidence-based dietary policy to enhance children's growth and cognitive development.

Abstract

This study aims to cluster the welfare levels of oil palm farmers in Gading Sari Village, Tapung, using the K-Means Clustering algorithm. The analyzed variables include land area, family dependents, average monthly income, additional income, and educational attainment. Previous studies have extensively discussed the welfare of oil palm farmers. This research uses clustering methods to uncover new and more detailed findings about the welfare of oil palm farmers in rural areas. This approach offers a fresh perspective and can be utilized to support data-driven decision-making processes by the government. Data were collected through interviews with 111 oil palm farmers, processed through normalization, and analyzed using the elbow method to identify the optimal number of clusters. The results identified three main clusters: low, medium, and high welfare levels. Land area and average monthly income were the most significant differentiating factors among the clusters. This study's fundamental distinction lies in applying the K-Means algorithm to integrate the socioeconomic aspects of oil palm farmers into specific clusters. These clusters will provide new insights into their welfare conditions. The findings are expected to assist governments and stakeholders in designing more effective and targeted development programs for oil palm

Abstract

This study systematically analyzes trends, patterns, and research gaps in STEAM (Science, Technology, Engineering, Arts, and Mathematics) studies published in the JPPIPA Journal from 2021 to the present. A systematic review of 35 empirical articles reveals that most studies employed a quantitative approach, particularly quasi-experimental methods, to assess STEAM’s impact on student learning outcomes. Project-based learning (PjBL) and problem-based learning (PBL) were the dominant instructional models, significantly enhancing critical thinking, problem-solving, communication, and collaboration skills. Some studies integrated local wisdom and technology-based tools such as e-modules, augmented reality (AR), and e-comics to boost engagement. However, limited qualitative research explores students' and teachers' experiences, and few long-term studies assess STEAM’s sustained impact. Research remains concentrated on primary and secondary education, with minimal focus on higher or vocational education, crucial for workforce readiness. Additionally, while critical thinking skills have improved, fostering creativity remains a challenge. Future research should incorporate qualitative and mixed-methods approaches, conduct longitudinal studies, and develop reliable STEAM assessment instruments to enhance implementation across diverse educational contexts.

Abstract

Total Intravenous Anesthesia (TIVA) is a widely used anesthetic technique that relies entirely on intravenous agents. However, one of its challenges is the potential reduction in oxygen saturation (SpO₂) during induction. Ketamine and propofol are commonly used anesthetic agents and their combination is hypothesized to optimize hemodynamic stability and prevent SpO₂ decline. Objectives: This study aims to evaluate the effectiveness of ketamine-propofol collaboration in maintaining oxygen saturation during TIVA induction at RSU Emanuel Banjarnegara. Methods: This study was a quasi-experimental study with 50 TIVA patients who met the inclusion criteria. Result: The study found that patients receiving the ketamine-propofol combination exhibited a more stable SpO₂ level compared to those receiving propofol alone. The mean decrease in SpO₂ was significantly lower in the combination group (p < 0.05), indicating the protective effect of ketamine in preventing hypoxia. The combo group also maintained hemodynamic indicators including blood pressure and heart rate better. Conclusion: The simultaneous injection of Ketamine and Propofol is beneficial in preventing a drop in SpO₂ 1 minute after induction of anesthesia compared to the combination of Propofol alone.

Abstract

Microplastic pollution in rivers can harm ecosystems and water quality. This study aims to assess water quality and the ecological risk of microplastics in 15 locations in the North Coastal Area of Situbondo, which include rivers and estuaries. Water samples were analyzed based on water quality parameters, such as pH, TDS, ammonia, salinity, turbidity, DO, and BOD. Microplastics were identified using binocular microscopes and FTIR, with characteristics (size, shape, color) recorded. The Water Pollution Index (IP) showed a mild level of pollution with values ranging from 1.322 to 3.897, where IP values 1-3 are considered "mildly polluted." Ecological risk analysis using the Pollution Load Index (PLI), Polymer Hazard Index (PHI), and Potential Ecological Risk Index (PERI) showed that industrial and residential areas had a higher risk of pollution. A significant correlation was found between microplastic color and water quality parameters based on CCA analysis. The results of this study indicate that despite moderate water quality, microplastics pose significant ecological risks, especially in areas with high human activity, emphasizing the need for better environmental management
