The chemistry module which integrated with Islamic values has already developed in thermochemistry and reaction rate. This research presented the availability of Islamic values in student’s handbook. The proper of chemistry module design based on BSNP criteria, and the response to chemistry module which integrated with Islamic values to teacher and university student. This research used the method of research and development. It consists of 3 steps which were analysis, design, and development. The instruments are checklist, questionnair based on BSNP criteria, and response questionnair. The result shown the lack of Islamic value in student’s handbook, chemistry module design is proper to used. The teacher and university student’s response are good and need no revision.Keywords:Islamic values; module development; statistics education research; students’ handbook

Practical activities play an important role in science education. Through it, students develop a deeper understanding of standing theoretical concepts, skill, utilization of technology, and methods for investigation with direct manipulation of related materials. Effective use of laboratories is one of the requirements in learning chemistry, especially in experiment material. However, problems that are often encountered in learning in the laboratory are laboratory management which includes the procurement process, application process, and the maintenance process. The research method used was observation, document recording and interview with all chemistry teachers and students at Labuhan Deli Senior High School and Percut Sei Tuan Senior High School, District of Deli Serdang, Indonesia. Stages in the research of this are (1) observation based on National Education Standards, (2) observation of chemistry experiments implementation, (3) observation of constraint and problems laboratory at school, and (4) determine alternative solution. The result showed that area of chemistry laboratory has suitable with BSNP standart, but the standard of facilities and infrastructure category reference scale (PAP), showed less category results. So the settlement by researchers on this problem is to do a simple practicum that can be done in an open space or using the technology (virtual laboratory) to increase the students’ skill in industrial 4.0.Keywords: Chemistry experiment, Laboratory, Facilities, Simple practicum, Technology

The laboratory is a place to train students' skills in conducting demonstration, experimental and scientific development practices. The provision of complete laboratory tools and materials and good laboratory management will make learning chemistry run optimally, but some high schools still do not meet the standards of facilities and infrastructure in the laboratory. Therefore, the researcher tries to collect the problems and constraints in the implementation of the practicum and find alternative solutions to the problem solving based on literature review and expert opinion. This research is a qualitative study which is a case study research in several high schools in Medan. The instruments in this study were student questionnaire, teacher questionnaire, principal questionnaire and observation sheet using Likert scale analyzed using the percentage formula. the results of the analysis of case studies conducted in a number of high schools in Medan, it can be concluded that, the area of chemistry laboratories in several schools in Medan meets BSNP standards, but there are still science laboratories used for chemical laboratories. The results of the analysis of equipment and materials that support the implementation of the practicum after the presentation of X1 schools 76.36%, X2 schools 65.67% and X3 schools 87.27%.

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).
