Abstract

The term "stunting" is used to describe the nutritional condition of a child based on anthropometric standards, based on the PB/U or TB/U index. The aim of the research is to analyze the factors related to the incidence of stunting in toddlers based on transcultural nursing in children aged 24-59 months in the Kaluku Bodoa Makassar Public Health Center TECHNICAL IMPLEMENTATION UNIT working area. The research design used in this study used a quantitative methodology, with a "cross-sectional" approach. Purposive sampling was used to select a sample size of 103 respondents. Data analysis was carried out with research findings showing that the majority of toddlers, specifically 72.8%, were categorized as stunting, as determined through the use of the chi-square test at a significance level of α=0.05, while 27.2% of toddlers were classified as normal from a total of 103 respondents. The research results show that there is a significant relationship between technological factors and the incidence of stunting (p=0.007), social factors and family support (p=0.000), cultural values and lifestyle factors (p=0.000), economic factors (p=0.010), educational factors (p=0.032), and the most influential factors identified were social factors and family support (p=0.000), with a 31 times higher risk of stunting. The P value is 0.000 < 0.005, with a 95% confidence interval (14.828-6.7013).

Abstract

Accurate temperature monitoring is essential in storage applications that require precise environmental control. This study aims to analyze the accuracy and stability of five digital temperature sensors—DHT11, DHT22, DS18B20, BMP085, and BMP280—by comparing their measurements with a mercury thermometer certified by the Indonesian National Standard (SNI) as the reference. Experiments were conducted in both indoor and outdoor environments using a NodeMCU ESP8266, with repeated measurements performed to evaluate consistency. The analysis was carried out using average measurement deviation and percentage error. The results show that the BMP280 provides the highest accuracy in indoor conditions, with an average deviation of 0.52 °C and a 2.0% error rate, whereas the DS18B20 demonstrates superior accuracy and stability in outdoor conditions, with deviations as low as 0.4 °C in several test points. The DHT11 and DHT22 remain suitable for simple applications with low precision requirements, while the BMP085 exhibits the lowest performance in terms of both accuracy and consistency. These findings offer practical guidance for selecting appropriate temperature sensors based on environmental conditions and application needs.

Abstract

The 2.3 GHz frequency band is one of the recommended spectrums for 5G deployment due to its favorable propagation characteristics and capability to support high data throughput. However, microstrip antennas operating in this band often suffer from limited bandwidth and radiation efficiency. This research aims to design and implement a 2×2 MIMO microstrip antenna using a square patch with a U-slot and an inset-feed technique to enhance bandwidth and radiation performance for 5G applications. The initial antenna dimensions were calculated using standard microstrip theory, followed by modeling and optimization using CST Microwave Studio Suite 2019. The optimized antenna was then fabricated and tested using a Vector Network Analyzer (VNA) and radiation pattern measurements. Experimental results show that the antenna operates around 2.3 GHz with bandwidth values ranging from 61 to 65 MHz, VSWR below 1.2, and an axial ratio of 1.23 dB, indicating circular polarization. Additionally, the measured gain reaches 6.98 dB. These results demonstrate that the U-slot modification combined with inset-feed implementation effectively improves antenna performance, making the design suitable for MIMO systems in 5G networks.

Abstract

Efficient, automated watering is crucial in modern agriculture. IoT (Internet of Things)-based automatic watering offers a solution to this challenge, particularly for peanut plants, which require precise and accurate watering. This research aims to design and test an IoT-based automatic watering system for peanut plants. The system is designed to optimize water use and increase efficiency in peanut cultivation. Identified problems include difficulty in determining the correct amount of water, water wastage due to manual watering, and inaccurate visual observations. This research focused on the design of the automatic water regulation system, the water pump control method, and the sensitivity of the soil moisture sensor in the system. Test results showed that the system performed well. The soil moisture sensor can detect water levels and automatically control the water pump. The water pump activates when soil moisture is below 30% and shuts off when it reaches 60%. There was no discrepancy between the sensor readings and manual calculations, demonstrating the system's accuracy.

Abstract

HIV (Human Immunodeficiency Virus) is a virus that infects cells in the body and weakens the human immune system, making it more susceptible to various diseases. Meanwhile, the symptoms of the disease arising from HIV itself are referred to as AIDS (Acquired Immune Deficiency Syndrome). Approximately 50% of people with AIDS in Indonesia are adolescents. Until now, HIV/AIDS has ranked second in East Java province. HIV/AIDS is classified as a dangerous disease because of the risk of death. Unfortunately, there is no treatment method or vaccine that could prevent this disease. This monitoring program to prevent the development of dangerous health cases such as HIV/AIDS is very helpful for local governments. Along with the development of information technology, the emergence rate of new HIV/AIDS cases can now be forecasted using machine learning as a monitoring tool to support. This machine learning-based monitoring program works with past data for statistical analysis. In this study, the methods used are Kalman Filter, Recurrent Neural Network, and Decision Tree. The Kalman Filter is a type of filter method that is used to predict the state of a dynamic, stochastic, linear, discrete system. A Recurrent Neural Network (RNN) is a development of a Neural Network. RNN deals with input sequence/time-series data by individual sector at each step and preserves the information it has captured at previous time steps in a hidden state. A Decision Tree is one of the classic tree-based prediction methods. The best error value (RMSE) achieved by each method is 0.0885 for the Kalman Filter, then for the Recurrent Neural Network method achieved 0.198, and the Decision Tree method successfully achieved 0.0287.

Abstract

Distributed photovoltaic (PV) generation has emerged as a key solution for enhancing the performance of medium-voltage (MV) distribution networks, particularly in isolated systems with limited conventional generation. This study investigates the impact of centralized and distributed PV integration on voltage profile and power losses in the 20 kV East Sumba distribution system. A steady-state load flow analysis using the Newton–Raphson method was performed in DIgSILENT PowerFactory under three PV penetration levels (20%, 50%, and 100% of peak load). The base-case condition shows significant undervoltage at remote buses and total active power losses of 474.47 kW, mainly due to long radial feeders and concentrated loading. The results indicate that centralized PV placement yields the strongest voltage recovery near the interconnection point at 100% penetration, whereas the minimum system power loss is achieved at 50% penetration. By contrast, distributed PV placement provides more uniform voltage support across remote buses, although with lower effectiveness in reducing total system losses. These findings reveal a clear operational trade-off between voltage improvement and loss minimization, implying that the preferred PV placement strategy should be selected according to the specific technical objective of the network. This study provides practical insights for planning and optimizing PV integration in weak and isolated MV distribution systems.
