Abstrak. Kemajuan Ilmu Pengetahuan dan Teknologi di abad 21 mengakibatkan terjadi pergeseran paradigma belajar yang tidak mengenal ruang dan waktu, sehingga kemampuan literasi digital, literasi sains, literasi bahasa, dan literasi matematika sangat perlu untuk dikembangkan. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan literasi Mahasiswa Calon Guru Fisika Fakultas Keguruan dan Ilmu Pendidikan Universitas Samudra. Metode Penelitian menggunakan metode pre-experimental design, dengan desain one group pretest-posttest design. Lokasi Penelitian pada mahasiswa angkatan 2016 sebanyak 22 orang. Tes kemampuan literasi sain berbentuk pilihan ganda dengan empat alternatif pilihan jawaban. Teknik pengolahan data menggunakan rumus N-gain yang ter normalisasi, dan uji t berpasangan (Paired Sampel t-Test) menggunakan SPSS versi 23. Hasil analisis data N-Gain menunjukkan kemampuan literasi sain pada setiap domain dan aspek kemampuan literasi sain sebesar 0,71 dan 0,76 dengan kategori tinggi pada materi listrik dinamis. Hasil ini diperkuat oleh hasil uji t berpasangan (sig.0.000.05) dapat disimpulkan model pembelajaran inkuiri berbasis virtual laboratory secara signifikan dapat meningkatkan kemampuan literasi sains mahasiswa calon guru fisika pada materi listrik dinamis.Kata Kunci: Literasi Sain, Model  Inkuiri, Virtual Laboratory, Listrik Dinamis Abstract. The advancement of Science and Technology within the 21st century has led to a shift of learning paradigm, which is no more influenced by space and time; so that the ability of digital literacy, science literacy, language literacy, and mathematical literacy is highly required to be developed. The purpose of this study was to find out the improvement of students’ literacy ability at Physics Education, Teacher Training and Education Faculty, Samudra University. The research method used in this research was pre-experimental design method, with one group pretest-posttest design. This research was conducted in the Physics class; and there were 22 students taking part within this study. A multiple-choice test, with four alternative answers, was applied in order to find out students’ literacy ability. The data were analyzed through N-gain formula, and paired t-test using SPSS, version 23. The result of N-Gain data analysis revealed that the scientific literacy ability in each domain and the aspect of the science literacy ability is 0.71 and 0.76 with high category in dynamic electrical material. This result is reinforced by paired t test result (sig.0.00 0.05), which can be concluded that inquiry model based on virtual laboratory can significantly improve students’ science literacy ability, considered as Physics teacher candidate, especially in dynamic electrical material.Keywords: Science Literacy, Inquiry Model, Virtual Laboratory, Dynamic Electricity

This research aims to find out the pre-service teacher’s physics attitude towards physics laboratory in one of the Universities in Aceh. The research method uses a quantitative descriptive approach. Data collection techniques used a scale questionnaire that was adapted from several previous researchers. The Subject of this study is 45 physics student prospective students who were taken from the semester, II, IV, and IV as subjects of the study. The data analysis technique is done by calculating the mean of each aspect and indicator and the independent t-test to see differences in attitudes based on gender. Overall, the results of the study showed a negative attitude towards physical practicum activities with the acquisition of a mean of 2.78. The statistical test results for normally distributed and homogeneous data show no significant differences (df. 43, sig. 0.90> 0.04) between the attitudes of male and female students. Negative attitudes towards physics laboratory are caused by the design of practicum verification that does not provide benefits to improve understanding, practice scientific inquiry skills, thinking skills, and solving physics problems. Efforts to improve attitudes toward physics practicum can be done through the design of practical activities oriented to humanistic psychology and constructivism by involving students actively investigating.

We suggest a simple, practical device with a wireless sensor network system that can be used to record and display data from a spring oscillation system in real-time on a website. The HC-SR04 ultrasonic sensor was utilized to detect changes in load position in the damped spring oscillation system, and the Node-MCU ESP266 was used to transmit data from sensor readings to the server over the internet network. The damping factor, damping coefficient, and spring damping frequency could be utilized to calculate the exponential function graph fitting outcome.

A Multitools instrument was developed to measure physical variables such as temperature, magnetic field, and light intensity. Multitools developed using the device of ATMEGA 8535 microcontroller that consists of three sensors: LM35 as a temperature sensor, LDR as a light sensor, and UGN3503 as magnetic field sensor. The design consisted of three stages, namely system design, hardware design, and calibration phase. The calibration test result of Multitools shows alignment level of the temperature sensor 0.9893, light sensor 0.9787 and magnetic sensor 0.9996. Measurement result displayed in physical quantities data and graph on the LCD screen of Multitools. The Multitools can be used in physics lab activity to reduce the effectiveness and train the students’ skill in understanding and interpreting the graph.
