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%.

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.

Kajian kandungan kafein yang berkaitan dengan cita rasa kopi unik dari Aceh, kopi Khop, masih terbatas. Studi ini bertujuan untuk menentukan hubungan antara kadar kafein dalam bubuk kopi Khop dan karakteristik sensorik dengan analisis regresi linear. Bubuk kopi Khop dipisahkan berdasarkan empat kategori: halus (fine, F), sedang (medium, M), kasar (coarse, C), dan original (O). Keempat jenis bubuk kopi tersebut diseduh dengan air panas (90 oC) lalu diuji karakteristik sensoriknya menggunakan uji organoleptik meliputi rasa asam dan pahit, aroma, warna, dan residu ampas. Sampel kopi tersebut juga diukur kadar kafeinnya menggunakan spektrometer UV-vis dan harga pH-nya. Analisis dengan regresi linear sederhana menunjukkan hubungan linear negatif antara kadar kafein bubuk F, M, dan C dengan skor deskriptor sensorik kopi Khop. Berdasarkan hasil uji tersebut, kadar kafein bukan merupakan faktor tunggal yang menentukan hasil penilaian karakter sensorik bubuk kopi Khop yang ditunjukkan dengan linearitas negatif antara kadar kafein dan skor aroma kopi.

Low student learning outcomes are a significant issue in high school colloid chemistry learning. Correspondingly, this research aimed to determine the effectiveness of scientific literacy-based student worksheets (LKPD) in colloid chemistry learning. A quasi-experimental approach, specifically the pretest-posttest control group design, was employed in this study. The experimental class, XI IPA-2, consisted of 15 students, while the control class, XI IPA-1, also included 15 students, with total sampling techniques used to select the sample. Test instruments were developed to collect student learning outcome data through pretest and posttest techniques. The effectiveness of student worksheets was analyzed using the N-gain test, independent sample t-test, and effect size tests. The N-gain results exhibited an average score of 0.7319, which was a high category for the experimental class, while the control class obtained a score of 0.5308, which was categorized as moderate. The independent sample t-test results indicated a 2-taliled significance score of 0.002 ( 0.05), demonstrating a significant difference between the learning outcomes of the experimental and control classes. Based on these findings, it can be concluded that scientific literacy-based student worksheets effectively improved student learning outcomes in colloid chemistry learning at the senior high school level.
