Selama pembelajaran jarak jauh, siswa mengalami kesulitan dalam memahami pelajaran kimia. Selain itu, siswa diberikan banyak tugas sehingga hal ini menyebabkan siswa melakukan penundaan pengerjaan tugas. Kemampuan self regulated learning yang dimiliki siswa mempunyai peran untuk mengurangi perilaku prokrastinasi akademik. Metode penelitian yang digunakan yaitu metode korelasional dan pengambilan sampel menggunakan teknik purposive sampling. Sampel penelitian yaitu siswa kelas XII SMAN 58 Jakarta, SMAN 64 Jakarta, dan SMAN 105 Jakarta jurusan IPA. Instrumen yang digunakan berupa angket self regulated learning dan angket prokrastinasi akademik. Hasil penelitian menunjukkan bahwa tingkat self regulated learning siswa masuk ke kategori tinggi dengan persentase 67,9%, dan tingkat prokrastinasi akademik siswa masuk ke kategori sedang dengan persentase 59,1%. Nilai koefisien korelasi (rxy) sebesar -0,228 dengan nilai signifikan sebesar 0,001 sehingga dapat diartikan bahwa terdapat hubungan negatif yang signifikan antara self regulated learning dengan prokrastinasi akademik siswa SMA pada pelajaran kimia selama pembelajaran jarak jauh.

Student misconception is one of the important concerns in educational research because it is disturbing students to understand the scientific concepts in learning. Misconceptions often occur in Chemistry learning, one of them on the concept of Buffer Solution. This study aims to identify students' misconception on the concept of Buffer Solution using Four-Tier Multiple-Choice (4TMC) test instrument in SMA Negeri South of Tangerang. The research method used is descriptive quantitative. The study was conducted on 07 August to 05 September 2019. The subjects of this study are the students of XII grade MIPA program in SMA Negeri South of Tangerang academic year 2019/2020 with the number of samples 134 students taken from four classes using the technique of Cluster Random Sampling. The research data was obtained from the students' answers on the 4TMC test questions. The data is processed based on the pattern of student answers are then grouped into the category of student understanding that is misconception, lack of knowledge, error, and understand the concept. The results showed that there was a misconception with a percentage (48,51%), and significant misconceptions identified in 2 of 5 subconcepts of Buffer Solution investigated, they are the subconcept of Buffer Solution Calculation (14.92%), The Role Of Buffer Solutions In The Body Of Living Things (15.67%). The result of the identification of student misconception is expected to identify misconceptions that occur in the students to be handled more quickly so as not to impede the students in learning.

This purpose of this study is to determinethe relationship between learning styles with unimodal, bimodal, trimodal, and quadmodal student chemistry learning outcomes. The research subjects were 160 students of class XI IPA SMAN 4 South Tangerang. The research was conducted because each student has a different learning style and affects learning outcomes. The learning style used is VARK (Visual, Audio, Read and Kinesthetic). Based on the results of the reliminary analysis, students do not know their learning styles and there are still many students who have chemistry learning outcomes below the Minimum Completeness Criteria (KKM). The research method used is a correlational method with a cross sectional approach. Data were collected by using questionnaires and documentation techniques. Before the questionnaire was given to students, the validity and reliability were tested. The results of bivariate analysis using the contingency correlation test obtained p-value <0.05, so it can be concluded that there is a positive relationship between learning styles and chemistry learning outcomes for students of class XI MIPA SMAN 4 South Tangerang. The results of the univariate analysis showed that the most common learning styles were quadmodal (Visual, Audio, Read and Kinesthetic) 54 students (34%), unimodal 37 students (23%), trimodal 36 students (22%) and bimodal 33 students (21%). The results of learning chemistry obtained low scores as many as 89 students and high scores as many as 71 students. Keywords Learning Styles, Learning Outcomes, VARK

The research aimed to develop a STEM-based chemistry enrichment book on electrochemistry and find out the students' responses to the book. This development process uses a mixed method Cresswell version; qualitative approach for the development stage using text analysis and quantitative method for data statistics using data analysis. An enrichment book indicator is generated, which has been integrated with each STEM component to become a reference for developing an enrichment book. Then, a STEM-based chemical enrichment book was made on electrochemical materials. It was reviewed by expert validation of media materials: four chemistry education lecturers and one chemistry teacher. The average percentage from enrichment book validation results for each aspect of eligibility were: content, presentation, language, and graphics. Each has a value of 98.5%, 87.5%, 100%, and 100%. The final enrichment book product was tested on 37 students at one of the senior high schools in Indonesia. The student's response test results were 81.34%, including the proper category in a very good predicate. The product of this study result was proven to have a positive response that can be used in chemistry learning. It can be used as teaching material for schools and also can support STEM education in Indonesia.
