Senyawa 2-aryl-3-nitro-2H-chromene merupakan senyawa yang dihasilkan dari analog hibrida nitrovinylstilbene yang berfungsi sebagai agen pro-apotosis terutama pada sel kanker payudara. Untuk mencari aktivitas biologis yang lebih baik, maka perlu dilakukan modifikasi senyawa, kemudian dilakukan studi hubungan kuantitatif struktur aktivitas (HKSA) dengan pendekatan Hansch berdasarkan analisis multiregresi linier dan penambatan molekul untuk menganalisa interaksi dari turunan 2-aryl-3-nitro-2H-chromene terhadap topoisomerase II. Deskriptor yang digunakan mewakili parameter hidrofobik, parameter sterik, dan parameter elektronik. Persamaan HKSA yang didapatkan divalidasi dengan menghitung nilai RMSD dan PRESS. Hasil persamaan HKSA terbaik adalah Log IC50 = 19.282 + 1.581 E-5 x (AM1_Eele) + 1.537 x (AM1_Homo) – 0.059 x (ASA_H) + 1.715 x (glob) – 1.278 x (Log P) + 0.137 x (vol). Hasil penambatan molekuler menunjukkan bahwa senyawa 1C mempunyai aktivitas terbaik dibanding senyawa lain dengan (ΔGbind) terendah (-9.0 Kcal/mol), dan hasil HKSA memiliki nilai IC50 prediksi terkecil (0.021145 μM).

This study aims to provide information on the influence of brand image, the
quality of education services on consumer satisfaction. This research uses survey method
with path analysis technique, with a sample of 244 respondents. The results of the study
prove that (1) there is a positive and significant influence between brand image on
customer satisfaction, by 66.7% (2) there is a positive and significant influence between
the quality of education services on customer satisfaction by 71.4% (3) there positive and
significant influence between brand image and education service quality on customer
satisfaction by 78.1%. In order to encourage the level of customer satisfaction, the Faculty
needs to pay attention to the expectations and complaints of its customers, and continue to
improve the quality of education services.

he purpose of this research is to know the subjective attitude of the academic community toward Muhammadiyah s acceptance in Muhammadiyah s Business Charity as an effort to face the difference of understanding to the society in Perguruan Muhammadiyah Tangerang. The approach used in this research is quantitative descriptive. The research location is Muhammadiyah University of Tangerang. The data source of this research is teachers and employees of Muhammadiyah College of Tangerang. Data collection techniques used in this study are observations and questionnaires. Data analysis using linear regression. The results of this study indicate that in implementing the Muhammadiyah Business Charity (AUM) activities teachers and employees are able to accept Muhammadiyah ideology and minimize the potential for conflict caused by ideological differences among organizations in society.

The purpose of this research was to (1) develop scales for measuring teaching practices and assessment practices in mathematics class; (2) identify the profile of teaching practices and assessment practices in mathematics class; and (3) examine the consistency between relevant factors in teaching practices and assessment practices in mathematics class. The methods of cross-sectional surveys and a scale development study were used to achieve that purpose. The participants in this research included two sample groups of primary school teachers in Jakarta. The first sample consisted of 252 teachers and the second sample consisted of 325 teachers. This research found that there were two factors in each dimension of teachers’ practices in mathematics class. Teaching practices included the relational and instrumental practices, while the assessment practices included the assessment for learning and assessment of learning. This research also found that most of the teachers leaned toward traditional practices for both teaching practices and assessment practices, and that there was a consistency between relevant factors in those teaching and assessment practices. A more detailed discussion can be found in the findings and discussion section.
