Abstract

Temperature measurement in water is crucial for various applications and technological advancements. Fiber Bragg Grating (FBG) sensors have shown significant potential in measuring water temperature, with advantages in accuracy, reliability, and resistance to extreme environmental conditions. In this study, we conducted a series of experiments to measure water temperature in the range of 4 to 25 degrees Celsius using FBG sensors. Through two experimental analyses of the FBG sensor's response to water temperature changes, we found that the sensitivity of the FBG sensor we used was 0.0101 nm/°C. The results of this research demonstrate that FBG sensors are capable of measuring water temperature with high sensitivity, accuracy, and stability.

Abstract

Misconception is an event of a wrong concept received by students after following a learning process, the concept received is not in accordance with existing scientific studies. This study aims to identify students' misconceptions on the colligative properties of the solution and the factors that cause misconceptions. This type of research is descriptive quantitative. The instrument used is a four-tier multiple choice diagnostic test. This study involved 34 students of class XII MIA at MA Khulafaur Rasyidin Sungai Raya. The results showed that the level of misconceptions of students had an average percentage of 34% with a moderate misconception category, where a total of 65% students experienced misconceptions in the sub-topic of vapor pressure depression, 26,30% students experienced misconceptions in the sub-topic of freezing point depression,  33,30% students experienced misconceptions in the sub-topic of boiling point elevation, and  26% students experienced misconceptions in the sub-topic of osmotic pressure. Based on the results of the interview, the factors causing misconceptions in this study consist of internal and external factors. Internal factors come from students, that are students provide concept ideas spontaneously based on their understanding without being investigated first, students provide incorrect reasoning, students are confused in connecting one concept with another, lack of interest and ability of students in learning chemistry. External factors come from the context and teaching methods, where one of the learners' discussion partners has misconceptions, the teacher is more dominant in providing chemical explanations in mathematical form, and limited experiments. Those misconceptions can be reduced by presenting the topic in an interesting way, using an experiment, or using multiple representations approach.

Abstract

This study aims to determine students' science process skills through practicum method on cell material for class XI IPA of SMA Negeri 1 Tapa. The research method used quasi-experimental, a posttest-only non-equivalent control group design. Data collection was performed through observation sheets and test questions. The data analysis used is the t-test. According to research conducted in class XI IPA 1 using the practicum method, students in the experimental class had an average science process skill score of 79%. In contrast, students in the control class, which did not use the practicum method, had an average of 55%. Therefore, the science process skills of students in the experimental class are higher than those in the control class due to the use of the practicum method. Teachers guide students in activities during the learning process by asking open-ended questions that spark a discussion. Students are therefore required to be active, creative, and able to collaborate during the learning process to meet the learning objectives and understand the concepts being taught easily.
