ABSTRAKKajian model hipotesis internalisasi nilai tauhid dalam materi sains (fakta, konsep, dan hukum) diharapkan dapat meningkatkan kontribusi relatif pembelajaran sains terhadap ketercapaian tujuan pendidikan nasional. Internalisasi nilai tauhid pada materi sains tidak akan mengurangi kadar keilmiahan sains itu sendiri. Bahkan, kajian ini dapat meningkatkan kualitas materi sains. Sains sebagai sarana untuk mengembangkan potensi kognitif, sains pun dapat menumbuhkan potensi nurani (afektif). Materi sains ini akan mampu menanamkan keyakinan tentang segala sesuatu yang ada di alam. Segala sesuatu yang hakikatnya diciptakan Allah, Tuhan Yang Maha Esa. Keyakinan ini dapat mendorong terhadap keyakinan tentang ketundukan, karakteristik dan keteraturan dari benda-benda yang Allah ciptakan (sunatullah), sehingga manusia dapat mempelajarinya. Semua ini akan memungkinkan tumbuhnya sikap positif, kagum akan kebesaran, kekuasaan dan kasih sayang Allah, menjadi motivasi untuk bersyukur, meningkatkan keimanan dan ketaqwaan kepada Allah yang Maha Kuasa. Internalisasi nilai tauhid pada materi sains dapat dilakukan melalui pengungkapan nilai/hikmah/makna/hakikat dari materi sains tersebut berdasarkan sudut pandang Islam.Kata kunci : Tauhid, Internalisasi, Materi sains.

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%.
Perubahan yang terjadi pada remaja baik fisik maupun psikologisnya berhubungan dengan produksi hormon seksual dalam tubuh yang mengakibatkan timbulnya dorongan emosi dan seksual. Fenomena pacaran yang ada di kalangan siswa SMA Asuhan Daya Medan ditemukan adanya kasusseksual yang dilakukan oleh siswa sehingga peneliti tertarik untuk meneliti hal-hal yang melatarbelakangi terjadinya perilaku seksual. Penelitian ini menggunakan pendekatan mixed methods dengan jenis penelitian eksplanatori. Populasi untuk data kuantitatif sebanyak 91 siswa (total sampling). Untuk data kualitatif diambil 3 siswa yang dijadikan subjek penelitian. Instrumen data kuantitatif berupa kuesioner sedangkan data kualitatif berupa wawancara terbuka. Analisis data kuantitatif secara univariat, bivariat, dan multivariat, sedangkan analisis data kualitatif dianalisis secara deskriptif. Ada pengaruh perilaku seksual remaja dengan sikap, agama, paparan media pornografi, orang tua, dan teman sebaya. Variabel paparan media pornografi dominan memengaruhi dengan nilai Exp(B) sebesar 2,398. Hasil uji Logistic Regression dengan nilai Overall Percentage = 94,5%. Yang melatarbelakangi terjadinya perilaku seksual remaja adalah faktor keterpaparan media pornografi, teman sebaya, sikap, orang tua, agama.
Teaching materials are one of the components for improving students’ scientific literacy skills, but teaching materials that exist today, especially about thermochemical materials do not yet have the maximum content of scientific literacy. Through the research design of research and development, scientific literacy-based teaching materials have been developed in thermochemical material. The stages of research include needs-analysis, product design development, validation and analysis. Therefore, the product result and testing phase are limited to effectiveness testing. From the results of the study, it was found that science-based thermochemical teaching materials for general chemistry courses had been successfully developed with the existence of scientific literacy aspects. Moreover, the aspect are the knowledge of thermochemical material which is the aspect of science as a torso, thermochemistry in context which is an aspect of science as a process of inquiry, the high level of thinking skills which is science as a way of thinking, and attitude which is an aspect of interaction between science, technology and society. The overall feasibility validation result is 86.42%, which means the teaching material is in the valid category without revision. Moreover, the readability of teaching material products has an average readability percentage of about 83.79%, which means that teaching materials are included in the criteria to be easily understood.
Information about score obtained from a test is often interpreted as an indicator of the student's ability level. This is one of the weaknesses of classical analysis that are unable to provide meaningful and fair information. The acquisition of the same score if it comes from a test item with a different level of difficulty, must show different abilities. Analysis of the Rasch model will overcome this weakness. The purpose of this study was to analyze the quality of the items by validating the national chemistry exam instrument using the Rasch model. The research sample was 212 new students of the Department of Chemistry at the State University of Medan. The data collected was in the form of respondent's answer data to the 2013 chemistry UN questions, which amounted to 40 items multiple choice and uses the documentation method. Data analysis technique used the Rasch Model with Ministep software. The results of the analysis show the quality of the Chemistry National Exam (UN) questions is categorized as very good based on the following aspects: unidimension, item fit test, person map item, difficulty test level, person and item reliability. There is one item found to be gender bias, in which men benefit more than women. The average chemistry ability of respondents is above the average level of difficulty of the test items
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
