Abstract

Noise is a sound that is not desired because it is not in accordance with the context of activity, space, and time so it can cause disturbances to comfort and even human health. Twoof the basic ingredients of a silencer are husk and bran. This research aimed to determine the effect and model of the relationship of the density of the sample mixture of husks and bran on acoustic waves' reflection coefficient and transmission coefficient. The method used in this research is experimental, using a mixture of husk and bran samples whose density consists of 5 variations. The results showed that the husk and bran mixture's sample density strongly affected the reflection coefficient (r = 0.947 to r = 0.966) and the transmission coefficient (r = -0.962 to r = -0.999). These resultsshow that the greater the sample density of the husk and bran mixture, the greater the absorption intensity fraction produced. Statistically, the level of influence is indicated by the correlation coefficient, whose value is around r = 0.95 to r = 0.99. Based on the results, the reflection and transmission coefficients are influenced by the density of the mixture of husk and bran samples.

Abstract

This study aims to thoroughly analyze the problems encountered in the Natural Science (IPA) learning process at SMPN 1 Suwawa Timur, considering the 21st-century curriculum demands that require the development of students' scientific attitudes and skills through direct experience. This research employs a descriptive qualitative approach, where data was collected through a closed questionnaire administered to 32 students of class IX A and in-depth interviews with the IPA subject teacher. The analysis results identified two major interconnected issues: (1) low student motivation and scientific attitude, and (2) sub-optimal utilization of school facilities and infrastructure. The low student learning motivation was confirmed by the teacher as a crucial obstacle, which ironically occurs despite the school having complete laboratory facilities. The root problem was found in the lack of teacher knowledge and professional competence in operating and utilizing laboratory equipment for practical activities. It is concluded that the minimal implementation of practical work due to limitations in teacher competence is the main factor contributing to low student motivation and learning achievement. Therefore, this study recommends the necessity of continuously enhancing teacher competence related to laboratory facility utilization to optimize the quality of the IPA learning process in the school.

Abstract

Misconceptions in vibration and wave topics remain a common problem in junior high school science learning, particularly due to the abstract nature of the concepts and their limited direct observability. This study aimed to analyze students' conceptual shifts on vibration and wave concepts through the implementation of a Deep Learning approach supported by a Mechanical KIT. The study employed a one-group pretest–posttest experimental design involving three classes, comprising one experimental class and two replication classes, with a total of 69 eighth-grade students serving as research participants. A three-tier diagnostic test consisting of ten multiple-choice items was used to identify students' conceptual categories, including guessing, lack of conceptual understanding, misconception, and sound conceptual understanding. The data were analyzed descriptively using SPSS to examine the direction and quality of students' conceptual shifts before and after the intervention. The results indicated that the Deep Learning approach, assisted by the Mechanical KIT, effectively facilitated positive conceptual shifts, as evidenced by a dominant transition from misconceptions, a lack of understanding, and guessing toward sound conceptual understanding across all classes. The most substantial conceptual improvements were observed in indicators related to the relationships among frequency, period, and amplitude, while relatively lower shifts occurred in concepts requiring higher levels of mathematical reasoning. These findings suggest that integrating a Deep Learning approach with concrete instructional media, such as a Mechanical KIT, is effective in promoting meaningful conceptual reconstruction and reducing misconceptions in vibration and wave learning.
