Published: December 2019

<p class="AbstractEnglish"><strong>Abstract: </strong>Knowledge construction from the beginning before students get formal learning (preconceptions or students' initial concepts) often does not match the knowledge received by experts, and becomes a misconception. Misconceptions on students need to be diagnosed and given a solution to improve learning, so that misunderstanding of the material can be corrected. This study aims to determine the effectiveness of the constructivism approach with the 5E method to remedy misconceptions on sound wave material. This research is a qualitative descriptive study with a sample of students of class XI MIPA 2 in 1 Turi Senior High School. This study uses a two tier test instrument. In addition to using a two tier test, interviews were conducted on several students to confirm the answers to the two tier test. Based on the results data, it was found that learning using the constructivism approach with the 5E method was effective in minimizing the average of students' misconceptions of 26%.</p>

<p><strong>Abstract: </strong>Indonesia's electricity consumption has increased every year. One way to overcome this problem is by utilizing renewable energy sources such as wind. Utilization of this energy uses wind turbines installed at locations that have met the requirements. Therefore, information on wind conditions in several layers is required by using radar products such as CAPPI, PPI, and HWIND which are processed using Rainbow 5 software and then interpreted in a daily wind speed graph. Data obtained from radar imagery of Syamsudin Noor Meteorological Station-Banjarmasin. And to determine the boundary conditions of the wind layer is determined according to the length of the turbine blades to calculate the minimum wind speed needed to drive the turbine blades. The results of this study show that wind conditions in layers of 100 to 600 meters tend to be the same, making it difficult to determine the maximum height of the wind layer and from 7 days of the observation sample, it is found that some average wind speeds per day are 4.076923 m / s, 4.777778 m / s, 4.393939 m / s, 0.75 m / s, 0.72973 m / s, 3.678571 m / s, and 1.4375 m / s, which are known to have not met the minimum wind speed requirements for wind farm (PLTB) to produce optimal energy.</p><p><strong>Abstrak: </strong>Konsumsi listrik Indonesia mengalami peningkatan setiap tahunnya.

Pemanfaatan energi ini menggunakan turbin angin yang dipasang pada lokasi yang telah memenuhi syarat. Karena itu, diperlukan informasi kondisi angin dibeberapa lapisan dengan menggunakan produk radar seperti CAPPI, PPI, dan HWIND yang diolah menggunakan perangkat lunak Rainbow 5 lalu diintrepretasikan dalam grafik kecepatan angin harian. Data diperoleh dari citra radar Stasiun Meteorologi Kelas II Syamsudin Noor-Banjarmasin. Dan untuk menentukan kondisi batas lapisan angin ditentukan sesuai panjang dari baling-baling turbin untuk memperhitungkan kecepatan angin minimal yang diperlukan untuk menggerakkan baling-baling turbin. Hasil penelitian ini memperlihatkan kondisi angin di lapisan 100 hingga 600 meter cenderung sama, sehingga sulit untuk menentukan ketinggian lapisan angin maksimum dan dari 7 hari sebagai sampel pengamatan didapatkan beberapa kecepatan angin rata-rata perhari antara lain 4.076923 m/s, 4.777778 m/s, 4.393939 m/s, 0,75 m/s, 0.72973 m/s, 3.678571 m/s, dan 1.4375 m/s yang diketahui belum memenuhi persyaratan kecepatan angin minimum yang diperlukan Pembangkit Listrik Tenaga Bayu (PLTB) untuk menghasilkan energi yang optimal.</p>

<p class="AbstractEnglish"><strong>Abstract: </strong>This paper reports the test results of a loudspeaker-based acoustic energy harvester with acoustic random noise sources from a motorcycle. The harvester consists of a quarter wavelength resonator and a subwoofer type loudspeaker with a nominal diameter of 6 inches. The motorcycle used in this experiment is 135 cc Bajaj Pulsar motorsport with modified exhaust from the GBS-Motosport Jakarta. The motor engine is operated at 3000 rpm, resulting in noise with a fluctuating Sound Pressure Level (SPL) in the range of (90-93) dB. Six variations of resonator lengths are used, those are 21 cm, 31 cm, 58 cm, 85 cm, 112 cm, and 139 cm. In this test, data of dominant frequency, SPL, and output rms voltage were taken for 15 minutes. The rms voltage is measured at 100 Ω load resistor. The results show that the 112 cm resonator produces the highest average rms electrical power, that is (0.21 ± 0.01) mW, which is obtained at frequency that fluctuates within (95-120) Hz. In addition, with random sound sources, SPL and its dominant frequency fluctuate greatly, so it will greatly affect the generated electric power. Further research is needed to enhance the output electrical power and anticipate the impact of frequency fluctuation which exists in random noise sources.</p><p class="AbstractEnglish"><strong>Abstrak: </strong>Paper ini memaparkan hasil pengujian alat pemanen energi akustik berbasis <em>loudspeaker </em>dengan sumber kebisingan acak dari mesin kendaraan bermotor.

Dalam pengujian ini, data frekuensi dominan kebisingan, <em>SPL</em> kebisingan, dan tegangan keluaran alat pemanen energi akustik diambil selama 15 menit. Tegangan <em>rms</em> keluaran diukur pada resistor beban 100 Ω. Hasil eksperimen menunjukkan bahwa resonator dengan panjang 112 cm menghasilkan daya listrik <em>rms</em> rata-rata tertinggi yaitu sebesar (0,21 ± 0,01) mW, diperoleh pada frekuensi yang berfluktuasi antara 95 Hz sampai 120 Hz. Selain itu, hasil eksperimen ini menunjukkan bahwa dengan sumber bunyi acak, <em>SPL</em> kebisingan dan frekuensi dominannya sangat berfluktuasi, sehingga akan sangat berpengaruh terhadap daya listrik yang dihasilkan.

Published: December 2019

Abstract
This is a brief report of a 17-year-old male who presented to the emergency department with odynophagia and a foreign body sensation in the throat after choking on a chicken wing. A soft tissue neck radiograph was performed which revealed a 4.6 centimeter linear object in the vallecula read by the radiology department as a chicken bone. The otolaryngology team was consulted and performed a nasopharyngeal laryngoscopy which did not reveal a foreign body in the upper aerodigestive tract. On physical examination, the right tonsillar fossa was tender to palpation. Upon further review of the radiograph, the right stylohyoid ligament was noted to be elongated and calcified. Thereafter, the diagnosis of Eagle syndrome was made. This case provides an important teaching point for providers by pointing out a syndrome that can mimic other disease processes. In addition, it emphasizes the importance of providers reviewing their own films.

Abstract
Background: The outcomes of smoking have generated considerable clinical interest in recent years. Although people from different countries are more interested to the topic of quit smoking during the winter, few studies have tested this hypothesis. The current study aimed to quantify public interest in quit smoking via Google.Methods: We use Google Trends to obtain the Internet search query volume for terms relating to quit smoking for major northern and southern hemisphere countries in this research. Normally search volumes for the term “quit smoking + stop smoking + smoking cessation” were retrieved within the USA, the UK, Canada, Ireland, New Zealand and Australia from January 2004 to December 2018. Seasonal effects were investigated using cosinor analysis and seasonal decomposition of time series models.Results: Significant seasonal variation patterns in those search terms were revealed by cosinor analysis and demonstrated by the evidence from Google Trends analysis in the representative countries including the USA (pcos = 2.36×10-7), the UK (pcos < 2.00×10-16), Canada (pcos < 2.00×10-16), Ireland (pcos <2.00×10-16) ,Australia (pcos = 5.13×10-6) and New Zealand (pcos = 4.87×10-7). Time series plots emphasized the consistency of seasonal trends with peaks in winter / late autumn by repeating in nearly all years. The overall trend of search volumes, observed by dynamic series analysis, declined from 2004 to 2018.Conclusions: The preliminary evidence from Google Trends search tool showed a significant seasonal variation and decreasing trend for the RSV of quit smoking. Our novel findings in smoking cessation epidemiology need to be verified with further studies, and the mechanisms underlying these findings must be clarified.
