Perbandingan Performa Sensor DHT11, DHT22, dan 808H5V5 terhadap Pengukuran Kelembapan Udara Berbasis Internet Of Things
Full text linkThis study aims to compare the performance of three air humidity sensors—DHT11, DHT22, and 808H5V5—integrated with an ESP8266 microcontroller based on the Internet of Things (IoT). The system was designed to monitor air humidity in real-time through a web server that displays measurement data from the three sensors along with a hygrometer as a reference. Data collection was conducted every hour from 08:00 to 17:00 under stable environmental conditions. The results show that the DHT22 sensor achieved the highest accuracy, with an average deviation of 0.3% compared to the hygrometer. The 808H5V5 sensor demonstrated the fastest response with an average deviation of 0.6%, while the DHT11 sensor had an average deviation of 1.1% and slower response time. All three sensors successfully transmitted real-time data through an accessible web server. Based on these findings, the DHT22 is recommended as the most accurate sensor for IoT-based humidity monitoring systems, while the DHT11 and 808H5V5 remain suitable for simpler applications requiring moderate precision and lower cost

Numeracy across field-dependent and field-independent cognitive styles of junior high students in Indonesia
No full textThis study explores differences in numeracy between junior high school students with Field-Dependent (FD) and Field-Independent (FI) cognitive styles. Using a qualitative descriptive approach, the study was conducted in two junior high schools in Kefamenanu, West Timor, Indonesia. Forty students, evenly distributed across the two schools, participated in the study. Data were collected through numeracy tests and in-depth interviews to examine students’ performance across three numeracy components: understanding, application, and reasoning. The findings reveal that students with an FI cognitive style generally demonstrated competence in all three components, although some experienced difficulties in reasoning tasks requiring critical evaluation and formal justification. In contrast, students with an FD cognitive style tended to achieve only the understanding and application components and faced persistent challenges in progressing to the reasoning component. These results highlight the importance of differentiated numeracy instruction. FD students benefit from visual representations, explicit guidance, and collaborative learning to strengthen foundational, whereas FI students require non-routine and argumentative tasks to enhance higher-order reasoning. This study recommends that educators and future researchers implement inclusive numeracy literacy practices aligned with students’ cognitive styles
