Abstract

The purpose of this study was to see and find out the implementation of the 2013 revised 2018 curriculum learning in high school chemistry learning. This study uses a library research method. Library research is an activity to gather information relevant to the topic or problem that is the object of research. The results show that in the 2013 revised 2018 curriculum planning program in improving the learning process, teachers must design lesson plans in accordance with the syllabus so that learning can run optimally. Learning evaluation is carried out to be able to detect the development of student learning achievement every day through identification of the competencies that have been achieved by students. The implementation of the 2013 revised 2018 curriculum learning is said to increase when in the 2013 curriculum learning process involves the linkage of Basic Competencies with the latest issues, conducive and comfortable learning, school involvement in providing motivation and the participation of parents of guardians in helping student discipline.

Abstract

Atoms and molecules in chemistry teaching in schools is usually not associated with a particular religion of the Qur'an, so as if the atoms and molecules that learning is a science that is separate and has no relations with Al-Quran. To show that the Koran is a guide for mankind, including studying the natural sciences including chemistry, the authors wanted to examine the problem of atoms and molecules based chemistry and the perspective of the Koran which aims to determine the understanding of atoms and molecules according to the concept chemical and Koran, aspects of what is contained in the Koran that can be used as a guide in the learning of atoms and molecules. Data collection techniques used in this study is a library (Library Research) is studying the Quran and studying reading books, journals, textbook, dictionary, and scientific works. From these studies show that the Koran was first explained the concept of atoms and molecules as well as parts and in the Koran there is the concept of atoms and molecules that are in line with the chemical concepts put forward by the chemist

Abstract

In addition of being dubbed as the city of "Serambi Mekah", Aceh is also famous as the city of "Thousand Coffee Shops". One of coffee dish that attracts consumers' is khop coffee (read: kopi khop) because it is served with a glass dish upside down. The khop coffee, a typical coffee drink from Meulaboh, West Aceh Regency, is served by reversing the glass that has been filled with coarse coffee powder on top of the pan. Therefore, it is deemed necessary to conduct a special study on the analysis of unique taste-determining compounds in khop coffee to elevate the local wisdom of the Acehnese to the scientific region. The aim of this study was to determine the concentration of caffeine compounds of khop coffee due to the modification of coffee powder diameter by using the thin layer chromatography (TLC) method and UV-Vis spectrophotometry. This study used four types of samples with diameter variations coffee, namely original, fine, medium, and coarse. The four samples were extracted with boiling hot water according to the same conditions when the bartender served it (90 °C) followed by liquid-liquid extraction using chloroform solvent. Dry extract was analyzed by using TLC followed by a UV-Vis spectrometer. The results showed that the concentrations of original, fine, medium, and coarse coffee were respectively 57.85%; 17.61%; 1.29%; and 0.83%.

Abstract

Research on the development of virtual books on geometri molecular form materials at MAS Ulumuddin Lhokseumawe, was motivated by the limited use of instructional media in learning process. The learning media used are reading books and LKPD, chemistry learning is also often considered difficult because generally the geometry molecular material is abstract and requires high imagination to understand it. Virtual books are media with animation in the form of software that can be accessed or opened via computers and laptops. The media is equipped with covers, instructions user, concept maps, materials, 3D molecular shapes and quizzes. The purpose of this study was to determine the development of a virtual book on molecular form materials using the development research method using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Data collection techniques are validation sheets and response questionnaires. Based on the results of validation I 83.2%, validator II 92.8% and validator III 89.6%, the average score of expert validators from the expert validation sheet is 88.53% with very good criteria of virtual book. Based on the data from the implementetion results involving 16 students as respondents, an average percentage of 92.18% was obtained, so it can be concluded that the students responses to the virtual book media were very interesting.

Abstract

The atomic structure is one of the chemical metrics studied in high schools and universities. The concept of atomic structure in learning chemistry in schools and universities is usually not associated with religion, especially the Qur'an, so as if learning atomic structure is a separate science and has no connection with the Qur'an. To show that the Qur'an is a guideline for humanity, including examining the natural sciences including chemistry, the authors want to examine the concept of atomic structure based on chemistry and the perspective of the Qur'an which aims to determine the concept of the development of atomic models, particles basic and electron configurations based on chemistry and the Qur'anic perspective. The data collection technique used in this study is literature (Library Research), namely studying the Qur’an  and studying reading books, journals, dictates, dictionaries, and scientific works. From this study shows that the Qur'an has been proven to explain the concept of atomic structure first and in the Qur'an there is the concept of atomic structure which is in line with the chemical concept proposed by chemists.
