Noise is still a serious problem, especially for people who live in urban areas with various kinds of activities. Sound absorbing material or acoustic material is a special material made for absorbing sound at a certain frequency. Materials that are soft, porous, and fibrous are believed to be able to absorb sound energy. Banana midrib and water hyacinth are examples of natural materials with porous characteristics, which used as sound absorbent materials in this study. This experiment uses the impedance tube method, with sound intensity measurements varied from level 1 to level 5 at frequencies of 200 Hz, 400 Hz, 600 Hz, and 800 Hz. Based on the results of the absorption coefficient values, banana midrib has the highest absorption coefficient at a frequency of 800 Hz, while water hyacinth has the highest absorption coefficient at a frequency of 600 Hz. Based on the results, the banana midrib is more effective than water hyacinth, as a natural acoustic material.

The impact of high-intensity noise can cause discomfort for crew and ship passengers. The noise is partly caused by the maine engine which is the biggest noise source. So it is necessary to find a solution on how to reduce noise and the impact of the noise. The purpose of this study was to determine the magnitude of the sound intensity and the effect of sound intensity on the comfort of the crew and passengers. The research was conducted using the Sound Level Meter (SLM) application. Measurements made in the passenger compartment and an average of 66.4 dB to 73.6 dB indicate that the ship's engine noise level when operating is included in the strong category according to Suma'mur's study, 2009, but does not cause deafness and hearing damage.

This study aims to determine the effect of guided inquiry learning model assisted by PhET (Physics Education Technology) on high school students' physics learning outcomes. The type of research used is quasi-experimental with pretest-posttest control group design. The population of this study were all students of class X MIA at MA PLUS NURUL ISLAM Sekarbela Mataram. The sample of this study was class X MIA 1 and X MIA 2 which amounted to 40 students with a sampling technique using the saturated sample technique. The sample used in this study was class X MIA-1 as an experimental class which amounted to 20 students and class X MIA -2 as the control class with a total of 20 students. Before being given treatment, both samples were given an initial test to determine their initial ability. Based on the results of the homogeneity test of the initial test, both samples have the same initial ability. The results of the final test of student learning outcomes obtained the average value of the experimental class 69.25 with the highest score of 85 and the average value of the control class 55 with the highest score of 75. The research hypothesis was tested by polled variance t-test with a significance level of 5%, and the results obtained tcount = 4.18, while ttable = 2.02. Based on these results, it means that tcount is greater than ttable, so H0 is rejected. Thus, it can be concluded that the guided inquiry learning model assisted by PhET (Physics Education Technology) has an effect on high school students' physics learning outcomes.
本研究旨在探讨PhET(物理教育技术)辅助下的指导性研究性学习模式对高中生物理学习成果的影响。使用的研究类型是准实验的前测后测对照组设计。本研究的人群为MA PLUS NURUL ISLAM Sekarbela Mataram X班MIA的所有学生。本研究的样本为X MIA 1班和X MIA 2班，共40名学生，采用饱和样本技术取样。本研究样本为X MIA-1班，实验班20人，X MIA -2班，对照班20人。在接受治疗之前，两个样本都进行了初步测试，以确定它们的初始能力。根据初始检验的同质性检验结果，两个样本具有相同的初始能力。学生学习成果最终测试结果为实验班平均69.25分，最高分85分;对照班平均55分，最高分75分。对研究假设进行抽样方差t检验，显著性水平为5%，结果得到tcount = 4.18, ttable = 2.02。根据这些结果，说明tcount大于ttable，因此拒绝H0。由此可见，PhET (physical Education Technology，物理教育技术)辅助下的指导性研究性学习模式对高中生物理学习成果有影响。

Tapes, radio, laudspeakers, TV, and VCDs are all sources of organized and controlled sound. However, if this regular and controlled sound emits a sound that exceeds the desired sound level threshold and declared as noise that causes disturbances to human health, especially the sense of hearing. Hearing apparatus, namely the ear functions as a phonoreceptor capable of responding to sounds in the range 0 - 75 dB without causing pain. The frequency to which the human ear can respond is between 20 - 20,000 Hz and is very sensitive to frequencies between 1000 Hz - 4000 Hz. This study aims to determine how much the measured sound intensity level of the music sound at the Sinta Pub Maumere Bar and determine the degree of music sound intensity level at the Sinta Pub Maumere Bar at the measuring point of the sound source. This research was conducted at the Sinta Pub Maumere Bar using observation and experimental methods. The results showed the measured level of music sound intensity ranged from 103.12 dB. The highest level of sound produced is 110.6 dB and the lowest music sound intensity level produced is 92.4 dB. Based on the measurement results, the music sound intensity level at the Sinta Pub Maumere Bar has a different value. This shows that there is a difference measuring levelat the position of the distance from the sound source to the intensity level of the resulting music sound.
