Abstract

Noise pollution can come from noise generated by nature, one of which is noise from river flows. Therefore, the aim of this research was to determine whether the sound intensity level of the river flow is still below the threshold value or whether it has disturbed human hearing. The research method used was to measure the sound intensity level of the Cinangneng-Bogor river flow by using a sound level meter application. Measurement of the sound intensity level was carried out at 5 measurement points, namely in the middle of the river flow, on the river bank, at a distance of 5 m, 10 m and 15 m from the river bank to the land. Each measurement was carried out for 120 seconds. The results showed that the sound intensity level of the Cinangneng-Bogor river flow at several measurement points had different values, namely from the middle of the river to away from the river the values were 96.34 DbA, 92.31 DbA, 78.93 DbA, 76.58 DbA and 76.32 DbA. In conclusion, the further away from the noise source, the lower the noise level. The sound intensity in the middle and on the river bank was above the threshold value.

Abstract

Most of the students stated that studying Physics using relatively thick textbooks tended to be boring. This has an impact on unsatisfactory learning outcomes. The purpose of this research is to develop a product in the form of a module that is compiled using the Predict-Observe-Explain (POE) learning model with a combination of learning videos from YouTube, and analyze the feasibility level. The research method used is by making a module on temperature and heat material, which includes learning videos in the form of a QR code that can be scanned via a smartphone. The parameters analyzed include the results of the validation of experts who include material experts, media experts, and linguists. Another parameter that was measured as the level of student interest in the module, with a sample of 10 students from SMAN 1 Dramaga, SMA Bumi Sejahtera, and SMA Hanura. The results showed that the assessments of material experts, media experts, and linguists respectively were 3.83, 3.32, and 3.47 with the criteria of "very decent". The attractiveness test results for SMAN 1 Dramaga, SMA Bumi Sejahtera, and SMA Hanura were 3.57, 3.36 with the criteria of "very interesting" and 3.03 with the criteria of "attractive". Thus, it is concluded that the POE-based physics module by utilizing the QR code and YouTube learning videos is very feasible to be used as a learning medium.
