Practicum modules are needed during the practical learning process activities that can be used by teachers and students. Science literacy must be mastered by students, because it is related to the environment. Science literacy is assessed from three aspects namely content, process and context. The purpose of this study was to determine the feasibility test and practical test of practicum modules based on science literacy for science learning in SMP Negeri 1 Langsa. This type of research is research and development which is modified into three stages of research implementation with the module trial stage developed in the form of research and information gathering, module design phase and module development stage with documentary study data collection techniques, questionnaires, and experiments. The scores obtained will be processed using descriptive analysis by conducting a feasibility test by material and media experts consisting of biology education lecturers while the practicality test uses a questionnaire distributed to students of class VIII at SMP Negeri 1 Langsa on Natural Sciences subjects. The results showed that the IPA practicum product modules analyzed consisted of three categories: the percentage value of the highly valid aspects with a value of 78% on the module quality element, while the practicality test consisted of three aspects namely the content, process and context aspects of the results of the three aspects. The percentage value of 82.8% of the aspects of positive student response content that practicum modules are used is very practical. Based on the values obtained that the IPA practicum module is feasible and practically used as a practical guide.

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

ABSTRAKLiterasi sains didefinisikan sebagai kapasitas untuk menggunakan pengetahuan ilmiah, mengidentifikasi pertanyaan, dan menarik kesimpulan berdasarkan fakta dalam rangka memahami alam semesta dan perubahannya akibat dari aktivitas manusia. Modul pembelajaran adalah bahan ajar yang disusun secara sistematis dan menarik yang mencakup isi materi, metode dan evaluasi yang dapat digunakan secara mandiri untuk mencapai kompetensi yang diharapkan. Kemunculan literasi sains modul praktikum IPA merupakan tujuan dasar dari penelitian adalah untuk mengetahui bagaimana pelaksanaan praktikum IPA yang dilaksanakan oleh guru berbasis literasi sains dan untuk mengetahui indikator -indikator Kemunculan literasi sains modul praktikum IPA di SMP Negeri 2 Kota Langsa. Penelitian ini menggunakan metode deskriptif. Hasil dari kemunculan literasi sains pada modul praktikum berdasarkan instrumen penilaian pada aspek konten dengan nilai 31% dinyatakan cukup yang jelas berkaitan pada kemunculan literasi sains. Pada aspek proses dengan nilai 37% yang pernyataan kadang -kadang adanya kemunculan literasi sains pada modul praktikum, sedangkan pada aspek kontek 50% yang menyatakan kadang -kadang berkaitan kemunculan literasi sains dimateri modul praktikum. Kata Kunci: Literasi Sains, Modul Praktikum dan IPA ABSTRACTIn the 21st century the importance of scientific literacy learning is a necessity for individuals who face the challenges of the development of rapid scientific progress. Since that, science literacy learning is a learning concept based on content, processes and contexts. The basis of this research is about practicum modules that apply the concept of scientific literacy. The purpose of this study is to find out the indicators of the scientific literacy in the practicum module in Junior High School 1 in Langsa City. The method in this study is descriptive quantitative. The results obtained in this study are: (1) the content aspect of the scientific literacy in practicum module is 39%, (2) the process aspect of the scientific literacy is 52% which stated that the scientific literacy sometimes appears in the practicum module; (3) the context aspect is 40% which stated that the scientific literacy sometimes appears in the practicum module. The result is that practicum module can be stated sufficiently related to scientific literacy.

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.

Computational chemistry is a branch of chemistry which is the theoretical translated into computer programs to calculate the properties of molecules and their changes. This study analyzes the need of computational-based chemistry practicum in the Basic Chemistry course at the Chemistry Education Study Program at Samudra University. This study was done by survey technique. Aspects analyzed in this study include: module analysis through a review of the Basic Chemistry practicum module used by the Chemistry Education study program, needs analysis through students' perceptions that has been carried out, and literatures analysis through computational studies for Basic Chemistry that have been developed. Basic Chemistry practicum implemented in Chemistry Education is a verification practicum (conventional), and it is necessary to implement a practicum that gives more freedom to students in exploring. Basic chemistry practicum in Chemistry Education is also not based on computational, so it is necessary to develop basic chemistry practicum activities that provide computational problem solving
