Every object has a tendency to maintain its state of motion. The concept also applies to rotating objects called moments of inertia. This experiment aims to explain the working principle and determine the magnitude of the moment of inertia of objects using a bifilar pendulum teaching aid based on the ATMEGA-16 microcontroller. The implementation method used is the experimental method. The working principle of the ATMEGA-16 bifilar pendulum microcontroller-based teaching aids uses the bifilar pendulum principle. The moment of inertia of an object can be measured using a measuring tool that works at the moment of the inertia oscillation method. The bifilar pendulum experiment consists of an object which is tied on either side by a rope and then attached to a support. Objects are deviated horizontally with a small angle to the equilibrium position and then released, the object will experience periodic oscillations. Based on the experimental results the shorter the distance of the two bifilars, the period will be even greater, and vice versa. The magnitude of the period (T) on the bifilar pendulum is inversely proportional to the root distance between the two bifilar (d). The results of experiments carried out for variations in rope length and the distance between the ropes. The moment of inertia based on experiments for variations in length of rope at 0.35 m is (I ± ΔI) = kg/m2 ; 0.45 m is (I ± ΔI) = kg/m2 ; 0.55 m then (I ± ΔI) = kg/m2 ; 0.65 m then (I ± ΔI) = kg/m2 and 0.75 m, (I ± ΔI) = kg/m2.. Furthermore, the moment of inertia is based on experiments for variations in the distance between the ropes at 0.1 m then (I ± ∆I) = kg/m2; 0.15 m then (I ± ∆ I) = kg/m2; 0.20 m then (I ± ∆I) = kg/m2; and 0.25 m then (I ± ∆I) = kg/m2. The experimental results show that the smaller the distance between the two ropes will produce conformity to the theory of the solid cylinder using the shaft approach through the center.©2019 JNSMR UIN Walisongo.

This study aimed to analyze the needs for developing critical thinking skills technology-based assessment instruments in English subjects for vocational school and find out the factors that can support and inhibit developing and implementing critical thinking skills technology-based assessment instruments. This study used the qualitative research method with a case study design. The subject of study was 5 teachers and 15 eleventh-grade vocational school students at Tangerang. Observations, interviews, and documentation were conducted to collect the data. After collecting the data, the researcher used triangulation to confirm the data. The data collected were analyzed to answer the research questions using several stages, namely condensation, display, and verification. The results showed that the development of technology-based assessment instruments of critical thinking skills on vocational school English subjects needs to be developed. The schools have facilitation for conducting a technology-based assessment. Students have never taken on critical thinking skills assessment. Teachers and schools did not have the development of assessment instruments of critical thinking skills so teachers have never conducted critical thinking skills assessments on English subjects. Moreover, the students still have some obstacles in English learning such as vocabulary, pronunciation, and grammar. Therefore, the teachers should help to improve students’ vocabulary, pronunciation, and grammar before conducting a critical thinking skills assessment.

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.

Research has been carried out using gravity methods to identify subsurface structures in the region of Kota Lama Semarang as a preliminary survey for disaster mitigation purposes. In processing gravity data to identify subsurface structures, several processing stages are carried out. The initial step is to make the initial correction in the form of tide correction and float correction then a further correction is performed until a complete Bouguer anomaly contour is obtained. From the complete Bouguer anomaly, regional and residual gravity anomalies can be separated. The separation of regional anomalies from Bouguer anomalies in this study uses the moving average method while residual anomalies are obtained by subtracting Bouguer anomalies from regional anomalies. In the study of identification of subsurface structures it is important to conduct regional and residual anomaly separations to interpret geological structures and obtain the targets sought. Regional anomaly values in the region of Kota Lama Semarang are between 28.0 mGal - 28.4 mGal while for residual anomalies have between 31.6 mGal - 32.8 mGal.
