AbstractThis study aims to analyze the needs before developing computational chemistry-based learning media on hydrocarbon materials. This research is classified as development research developed with the ADDIE model. It's just that the stage used in this study is only limited to the analysis stage. Data collection in research is carried out by literature study methods and field studies with research instruments in the form of questionnaires on learning media needs and interviews by teachers. The location of this study is SMA Negeri Modal Bangsa Arun. Based on the results of interviews with chemistry teachers, it was found that learning hydrocarbon material at the high school level requires more effort because students must understand molecular structure, chemical bonds, and atomic structure. This makes students less understanding of concepts microscopically and can also cause misconceptions. Then, the results of the needs analysis show that there are still limited learning media that support microscopic concepts, especially the shape of molecules in 3-D. Based on the results of this study, it can be concluded that it is necessary to develop computational chemistry-based learning media on hydrocarbon materials.

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).

A research has been conducted to analyze the effect of remedial application on the learning outcomes of high school class XI students on Hydrocarbon material with the aim of knowing: (1) learning outcomes of students who do not apply remedial, (2) learning outcomes of students after remedial treatment, (3) the effect of remedial application on learning outcomes, and (4) students' perceptions of hydrocarbon learning. The results showed that: (1) the average value of the pretest was 62.22. (2) After remedial treatment for 4 times (5 times posttest) the results were obtained: posttest 1 with an average of 75.28, posttest 2 with an average of 72.22, posttest 3 with an average value of 78.18, posttest 4 with an average of 90, and posttest 5 with a value of 70. (3) the effect of remedial on student learning outcomes can be seen from the decrease in students who take remedial classes and also the average value that increases gradually for each remedial class conducted. (4) Based on the results of the questionnaire given, it can be concluded that students in both experimental classes like learning chemistry. This shows that students' motivation towards learning chemistry is quite good.

During learning students face difficulties in understanding abstract chemistry topics. Currently there is no appropriate media to be applied in the learning process in order to increase students' abilities. Therefore, a study was conducted using macromedia flash based on computer animation to improve learning outcomes in Madrasah Aliyah Negeri (MAN) 2 Medan Model schools in the Haloalkana sub discussion. This study aims to determine the effect of macromedia flash based on computer animation media on student learning outcomes in the haloalkane sub-discussion and to determine the correlation between the responses given by students to macromedia flash based on computer animation media in the haloalkane sub-discussion. The population of these two samples was taken using random sampling technique, namely class XII IPA 9 as the experimental class and class XII IPA 10 as the control class. The type of this research is quasi-experimental using the pretest and posttest models. Data collection was carried out using multiple choice instruments and response questionnaires. Based on the results of the study, it was found that there was an increase in student learning outcomes between the experimental class and the control class after the implementation of computer animation-based macromedia flash in the Haloalkana sub-discussion at MAN 2 Model Medan and there was a relationship between the responses given by students to computer animation based macromedia flash media in improvement of learning outcomes.
