The aim of this research is to analyze students' needs for computational chemistry-based learning media on atomic structure and chemical bonding in the Basic Chemistry course. The population of this study were the first grade students of the Chemistry Department, FMIPA Unimed. The number of samples in this study was 93 students from three classes. The instruments used are multiple choice questions and questionnaires to determine mastery of atomic structure and chemical bonding. The research results show that the average score is 34.430 (poor category). The average score achieved in atomic structure material was 33.16 (very poor). The lowest score achieved in the atomic properties sub-material was 9.3. The average score achieved in chemical bonding material was 36.1 (very poor). The lowest score achieved in the properties of ionic compound sub-material was 17.5. The results of the questionnaire showed that the atomic structure material that students considered the most difficult was the wave mechanics atomic model at 72.233 (quite difficult), while for chemical bonding material it was the octet and duplet rule at 71.055 (quite difficult).

This study aims to show the feasibility of using the lectora inspire learning media based on BSNP criteria; show whether the discovery learning model has an effect on learning outcomes; show learning achievements by comparing them to the KKM; and show the correlation between motivation and learning outcomes with the discovery learning model using the lectora inspire learning media. This study uses the ADDIE approach. The research on the implementation stage of using the lectora inspire learning media was conducted with Pre-Experiment Designs in the form of One-Group Pretest-Posttest Design. The sample selection was carried out using the purposive sampling technique, the sample studied was 41 students of SMA Negeri 7 Medan. The results of this study indicate that the average feasibility of using the lectora inspire learning media on all BNSP criteria is in the very feasible category; its use has an effect on improving student learning outcomes; the learning achievement obtained with the discovery learning model using the lectora inspire learning media is higher than the KKM; and student learning motivation is significantly correlated with their learning outcomes. It can be concluded that the lectora inspire media product obtained from this study is an innovative media product.

This study aims to develop a problem-based learning (PBL) module integrated with scientific literacy on the reaction rate material. The type of research used is Research and Development (R&D). The subject of this study is a PBL-based module integrated with scientific literacy. The object of this study is the chemical reaction rate material. This study refers to the steps of Borg and Gall but is limited to 5 steps or stages. The steps begin with data and information collection, PBL-based module development planning, initial product development, initial field trials, and revision of trial results. The developed module is validated and tested. Meanwhile, to see the attractiveness of the module, a data collection method is carried out using a research instrument in the form of a questionnaire. The results of the study showed that the PBL-based module integrated with scientific literacy on the chemical reaction rate material was declared feasible after validation. And declared interesting after obtaining a very interesting category percentage. It can be concluded that the development of a problem-based learning (PBL) module integrated with scientific literacy on the reaction rate material has been successful and can be used in learning activities.

In stoichiometry learning process, mostly educators focus on calculations. Students are not invited to think more critically about stoichiometry application in life. This constraint makes teachers have to develop new learning models, including Inquiry Based Learning (IBL) model, and Science, Technology, Engineering, Mathematics (STEM) based on chemical literacy. This study aims to develop general chemistry teaching materials on stoichiometry using IBL and STEM models based on chemical literacy that are feasible (valid) and capable of improving students' LOTS and HOTS abilities. The development model used is the ADDIE model, with research subjects of 34 students. The result shows that stoichiometry teaching materials using the IBL STEM model based on chemical literacy are valid (feasible) to be applied in learning with an average score of 4.42 for the material aspect and 4.55 for the design aspect. The developed teaching materials have been proven to significantly improve students’ LOTS and HOTS abilities.

This research aims to synthesize and characterize the complex compounds Hexathiocyanatoiron(II) [Fe(NCS)6] 4- and Tetrapyridinedithiocyanatoiron(II) [Fe(NCS)2(Py)4]. The synthesis of these complex compounds was conducted in the Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, Medan State University, while magnetic susceptibility measurements were carried out using the Magnetic Susceptibility Balance (MSB) instrument in the Inorganic Chemistry Laboratory, Bandung Institute of Technology. The complex compound synthesis involved the reaction of Iron(II) sulfate heptahydrate with Potassium thiocyanate and Pyridine compound in a 1:2 and 1:2:4 molar ratio. The synthesis process was conducted through a direct reaction method in a polar solvent. The obtained results include Hexathiocyanatoiron(II) complex compound, [Fe(NCS)6] 4-, which is pale yellow crystalline with a yield of 32.76%, and Tetrapyridinedithiocyanatoiron(II) complex compound, [Fe(NCS)2(Py)4] which is dark purple crystalline with a yield of 52.62%. These compounds exhibit a melting point of 219℃. Magnetic susceptibility measurements using the MSB instrument revealed a magnetic susceptibility of 6.69 BM (paramagnetic) for the Hexathiocyanatoiron(II) complex[Fe(NCS)6] 4-, and a magnetic moment of 5.61 BM (diamagnetic) for the Tetrapyridinedithiocyanatoiron(II ) complex [Fe(NCS)2(Py)4].
