Abstract

Perkembangan sains dan teknologi, alat ukur digital telah banyak direalisasikan menggunakan sensor suhu DS18B20. Namun, belum adanya alat ukur suhu dalam bentuk Celcius, Reaumur, Fahrenheit dan Kelvin yang secara praktis terlihat pada LCD. Penelitian pengembangan ini bertujuan untuk merancang bangun alat ukur suhu digital menggunakan sensor suhu DS18B20. Kelayakan alat ukur pembelajaran fisika ini diukur menggunakan keakurasian sensor yaitu nilai error dan nilai akurasi alat ukur terhadap termometer pembanding dan teori. Hasil penelitian ini menunjukkan bahwa keseluruhan alat ini dapat berjalan dengan baik dan dapat membantu dalam proses pembelajaran. Alat ini mampu menampilkan hasil pengukuran suhu pada LCD berupa skala Celcius, Reaumur, Fahrenheit dan Kelvin secara bersamaan. Tetapi penelitian ini masih memiliki kekurangan yaitu apabila ingin mengukur suhu yang sangat panas diatas 85°C, alat ini tidak dapat bekerja secara efektif karena menghasilkan data yang error.

Abstract

Momentum is one of the physics topics that students can better understand with practical activities. The problem found in using the ticker timer as a speed gauge in the collision practicum is that the measurement process interferes with the system being measured. This research develops a collision practicum tool using a microcontroller and ultrasonic sensor as a distance recorder. The glide track used is an air track. Based on the research conducted, it can be concluded that the collision practicum tool with a microcontroller and a glide track in the form of an air track can work well. The distance recorder or DRD is capable of recording distances every 0.2 seconds. The ultrasonic sensor as a gauge has an accuracy of 99.6% and a relative error of 0.56% for sensor 1. Meanwhile, sensor 2 has an accuracy of 99% and a relative error of 0.85%. Through the distance data obtained, it is possible to obtain an increase in momentum before and before the collision.

Abstract

Rebana/tambourine is a traditional musical instrument which is consist of many kinds. Rebana/tambourine was designed manually and received by the manufacturer with a sense of spirit and their own feelings based on their experiences. Human’s sense of hearing can distinguish between high and low tones, but cannot know surely what kind of tone was heard by them. It is very important for a musician to know whether the instrument is already generating correct tones. Because of that, this research was conducted to analyzed the characteristics of sunds frequency in tambourine/rebana. Tambourine/rebana is traditional musical instrument that do not have a standard tone yet as other musical instruments. Each tambourine generated has a difference in each of her tuning. So, it is hopefully that results of this research can be used to decide the standard of tambourine/rebana musical instrument. This research was conducted used software based on android that is android mobile phones. The android mobile phones has been equipped with an android device audio frequency counter which can directly display the value of the frequency of the sound of tambourines observed. By charging every area constantly, can be obtained the resonance frequency value of tambourine directly on the audio frequency counter column. average resonance frequency obtained from this research to tambourine successively from keplak, hadroh and bass is 750-1251 Hz, 681-1189 Hz, 630-1084 Hz, 503- 736 Hz, 270-448 Hz, 227,5-382 Hz, 146-332 Hz, 145-283 Hz. Keywords: Acoustic, tambourine.

Alat praktikum yang dirancang terdiri dari (1) tabung isolator berbentuk silinder, (2) elemen pemanas berbentuk silinder, (3) sumber tegangan AC, (4) sensor suhu digital, dan (5) material cair yang akan diukur nilai konduktivitas termalnya. Data profil distribusi temperatur yang diperoleh kemudian digunakan untuk menghitung nilai konduktivitas termal zat cair. Adapun nilai konduktivitas termal air pada suhu ruang 31°C diukur menggunakan alat praktikum yang dikembangkan yaitu 0.60 Wm-1K-1. Berdasarkan hasil penelitian, dapat disimpulkan bahwa alat praktikum konduktivitas termal zat cair pada geometri silinder yang dikembangkan tidak dapat secara langsung mengukur nilai konduktivitas termal zat cair.

The purpose of this research is to design a liquid thermal conductivity practicum instrument on a temperature sensor-based cylinder geometry. The practicum instrument that is designed consists of (1) a cylindrical insulator tube, (2) a cylindrical heating element, (3) an AC voltage source, (4) a digital temperature sensor, and (5) a liquid material for which the thermal conductivity value will be measured. The temperature distribution profile data obtained are then used to calculate the value of the thermal conductivity of the liquid.

Abstract

The Partnership for 21st Century Learning (P21) developed the Framework for 21st Century Learning to help education practitioners integrate skills into lesson teaching. This framework describes the skills, knowledge, and expertise that students must master in order to succeed in work and life. One of the skills that must be mastered by students in facing the 21st century is the 4C skill which consists of critical thinking, communication, collaboration, and creativity skills. This study aims to analyze the growth of the 4C skills of SMK students as the effect of implementing the use of PjBL STEM-based digital physics modules. This research is an experimental study with the before-after method, which compares the conditions before and after the implementation of learning activities. Data was collected by filling out a questionnaire with a Likert scale by students. The results showed that the 4C skills of vocational high school students grew significantly.

Abstract

Local wisdom needs to be maintained, protected and preserved, so it does not become extinct. Therefore, scientific studies on extracting local wisdom from the community in schools are increasingly needed. There have been many previous ethnoscience studies, but there have yet to be any ethnoscience studies in the Temanggung district, Central Java, Indonesia. The purpose of this study was to identify and reconstruct the original science of the community contained in the presentation of the art of cengklungan music into scientific science in Ethno-STEM teaching materials. Data collection was carried out in Geblog Village, Kaloran District, Temanggung Regency, Indonesia. The research method used is descriptive qualitative with data collection techniques through observation and interviews. The obtained data is then analyzed, verified, reduced, and reconstructed into scientific science. The results showed that there were several studies of ethnoscience in the presentation of the art of cengklungan music on the material of vibration, waves, and sound. Three main elements in the presentation of the art of cengklungan music are vocals, instruments, and dance. The ethnoscience study is integrated into Ethno-STEM-based teaching material.
