Abstract

This study aims to develop a tool that can assist nurses in examining patients by displaying sounds and signals on a TFT LCD screen. This tool uses the MAX 9814 sound sensor, which converts sound into an electrical signal. This sensor will generate a voltage when the diaphragm inside it moves back and forth. To design this tool, researchers used a series of high pass filters and low pass filters with a cut-off frequency of 333 Hz - 714 kHz. During testing of this tool using the MAX 9814 sensor mounted on a stethoscope, the signal appears stable on the TFT LCD screen and sound can be played properly. However, if the placement of the stethoscope is not correct during the examination, this can also affect the signal and sound produced. This tool should not produce a clear and loud sound when checking, because if this happens, the inspection cannot be carried out optimally. This research also produces a signal shape that is almost similar to the signal on the phantom. It is important to note that the MAX 9814 can work optimally if it is not exposed to environmental noise. Therefore, if this equipment is used in a noisy environment, the signal and sound produced may be disturbed by environmental noise. This research was conducted with the aim of making it easier for doctors and nurses to carry out portable examinations, as well as to monitor signals and sounds easily.

Abstract

Bullying is a common problem among elementary school students and may negatively affect their psychological well-being and learning process. Interactive education has the potential to improve students' knowledge and awareness regarding bullying prevention. This study aimed to evaluate the effectiveness of interactive education in improving students' knowledge of anti-bullying. A pre-experimental study with a one-group pretest-posttest design was conducted involving 42 sixth-grade students at SD Negeri 1 19 Nopember, Kolaka Regency. The intervention consisted of interactive educational sessions including participatory lectures, group discussions, educational videos, PowerPoint presentations, and anti-bullying posters. Students' knowledge was assessed using a 10-item questionnaire before and after the intervention. Data were analyzed descriptively using mean scores and knowledge-level distribution. The mean knowledge score increased from 6.45 ± 3.21 before the intervention to 7.81 ± 2.80 after the intervention. Following the educational program, 19% of students demonstrated a high level of knowledge, 45% had a moderate level, and 36% remained in the low category. Most students were able to identify the definition and impacts of bullying and recognized the importance of reporting bullying incidents, although some still experienced difficulty distinguishing different types of bullying. Interactive education effectively improved elementary school students' knowledge and awareness regarding bullying prevention. This approach may serve as an effective school-based health promotion strategy to prevent bullying. Establishing a school anti-bullying team or organization is recommended to sustain bullying prevention efforts.
