Abstract

Breast cancer is a disease with abnormal cell proliferation at breast tissue that can invade the surrounding tissue and spread to another organ. Based on WHO (2014) at 2012, there are 48,998 breast cancer cases on women in Indonesia with 19,730 death cases. In breast cancer, overexpression estrogen receptor alpha (ER-?) usually observed. Hence ER-? became the focus of prevention and therapy for breast cancer. In vitro study of emodin shows IC50 2.7 M and Ki 0.77 M on ER-?. In silico research using docking protocol and post docking analysis protocol shown that emodin was not an active ligand on ER-?. The outcome shown as ChemPLP score with average -75.292 and PLIF bitstring. Emodin binds with LEU346, LEU387, and ARG394 residue. Currently, the protocol that used in this research has yet identified marginal compound like emodin as an active ligand on ER-?.

Abstract

The research presented in this article aimed to provide a full quarternary structure of human matrix metalloproteinase 9 (MMP9) enzyme with a ligand in the catalytic site for structure-based virtual screening. The enzyme plays an important role in wound healing of diabetic foot ulcer. By employing the primary structure of the enzyme obtained from UniProt database (UniProt:P14780), the theoretical structure of full apoenzyme of the human MMP9 (PDB:1LKG), the crystal structures of the catalytic domain (PDB:4H3X) and the hemopexin domain (PDB:1ITV) of the human MMP9, homology modeling studies have been performed. The ligand N-2-(biphenyl-4-yl-sulfonyl)-N-2-(isopropyloxy)-acetohydroxamic acid (CC27) or N-hydroxy-2-[(4-phenylphenyl)sulfonyl-propan-2-yloxyamino]acetamide (IUPAC version) from PDB:4H3X was embedded in the catalytic site of the enzyme. The modeling made use of the modules of homology modeling in YASARA structure. Subsequently, molecular dynamics (MD) simulations in YASARA structure were performed to examine the stability of the enzyme. The homology model was found stable after 5.05 ns and the lowest energy of the model was found at the 6.40 ns of the MD production run. This lowest energy snapshot was then energetically minimized and analyzed for its applicability for virtual screening. This optimized model was then stored in Mendeley Data (DOI: 10.17632/4gsb4p75gz.1).

Abstract

Platelet-activating factor receptors (PAF-r) is known as one of the receptors that affect asthma, while the Y-21480 ligand is reported as an effective, specific, and active PAF-r antagonist for asthma patients. Research in building structure-based virtual screening protocol (SBVS) for identification of PAF-r ligand inhibitors has been performed, the receptor crystal structure was obtained from the Protein Data Bank (PDB ID: 5zkp), while the ligand used as a leading compound is Y-24180, obtained from U.S. National Library of Medicine. Interactions between ligands and receptors are observed through molecular dynamics simulations using the YASARA program at intervals up to 20 nanoseconds, ligand-receptor binding stability occurs after a time interval of 2 nanoseconds, the lowest ligand-receptor binding energy occurs at a time interval of 1,401 picoseconds. Internal validation by re-docking 1,000 times the ligand to receptor resulted in a value of Root Mean Square Deviation (RMSD) of 0.6037 Å,  confirmed that SBVS protocol was accurately able to reproduce the Y-24180 ligand pose on the 5zkp crystal structure,  the protocol can be used as a new approach for investigation or design of compounds that have therapeutic potential as anti-asthma.

Abstract

The development of the modern age is a lot of changes in education is the paradigm of teacher-centered learninginto student-centered learning which has a very important role in maximizing its competence in classroom management. One of the lessons in chemistry education that has problems is organic chemistry courses. Based onthe reflections applied to teachers and students "What has been gained from the learning process?", "What is thevalue obtained while the process is underway?" And "What will be done next (implementation)?". The results arestill very unsatisfactory, this is due to the limited ability of lecturers in the learning process. Associated with these conditions, then of course required intensive changes and planned for comprehensive improvement associated with the input to be generated. Efforts to be made is to improve the paradigm of learning. The selected learning paradigm is Reflective Pedagogy Paradigm (PPR). Reflective Pedagogy Paradigm was chosen because based on the results of research can improve the performance of lecturers in teaching, improve the readiness of lecturers in teaching, and make students able to reflect the learning process, and students become more active. The research was conducted following a workshop with lecturers who have implemented Reflective Pedagogy at Sanata Dharma University Yogyakarta. Stages in Reflective Pedagogy are context, experience, reflection, action and evaluation. It is expected by the end of two meetings. To be able to apply PPR, a lecturer needs to be equipped with special training on PPR-based teaching strategies as well asreflection skills (ICAJE, 1993, Gwaza et al., 2010; Schaub-de Jong dkk.2011; Wijoyo et al., 2016). Based on the results of the teacher reflection, it is increasingly realized that the preparation of learningis very important, and it is realized. While based on the results of reflection students stated that the purpose oflearning is clear, the material relevant to the profession of students, and understanding of the material becomeseasier, and the moral values for students. This case study is also in line with previous research that John Dewey(1933), He argued that learning from experience is enriched by reflecting on experience and Donald A. Schön (1987) theorized that reflective practice represents an important factor to improve professional activity. Jack Mezirow, (1991, 2000) gives reflection a central role in learning because through it we become aware of the ways in which we interpret reality and give meaning to actions and behavior. Writing-to-learn tasks should encourage students to conceptualize writing in a way that emphasizes exploration, expressive inquiry, discovery, problem-solving, decision making and knowledge construction.Key Word: Reflective Pedagogy Paradigm, case study, Organic Subject

Abstract

Environmental education is an aspect of education for students who are important to support life in the future. In the learning process there are several factors that influence success in learning. One of them is the ability factor of teaching from a teacher include material, method and learning media. However, there are important factors that need to be considered, namely the ability of teachers to reflect themselves during the learning process. Therefore it is necessary for the research to know the reflection of teachers in the learning process. This study aims to determine the effect of teacher reflection on student learning outcomes. The study involved as many as 15 students of English education. Data obtained in the form of student reflection data, questionnaire value of proenvironment attitudes. The data obtained were analyzed using Paired Samples T-Test. The results showed that the process of reflection that has not been optimal can’t improve the quality of learning.Keywords: pro-environment, reflection of paradigm pedagogy, lecturer, learning

Abstract

Profesionalisme guru penting dalam menunjang proses pembelajaran di kelas. Indonesia adalah negara dengan kualitas pendidikan yang belum baik. Banyak faktor yang menyebabkan hal tersebut. Salah satu faktor adalah Sumber Daya Manusia, Guru. Seorang pendidik di sekolah dituntut memiliki 3 kompetensi wajib  yaitu  pedagodik,  social  dan professional. Pada  kompetensi  pedagogic menjadi kebutuhan mutlak bagi seorang guru. Untuk menjadi guru yang mampu mengajar di kelas dengan baik membutuhkan pengalaman yang cukup banyak dan waktu yang lama. Namun, jika harus demikian makan kebutuhan guru di lapangan  akan  sulit  terpenuhi.  Ada  salah  satu  cara  yang  mampu  untuk membantu meningkatkan kapasitas guru dalam mengajar. Alternatif tersebut berupa kemampuan refleksi diri seorang guru. Kebiasaan refleksi yang saat ini ada  pada  beberapa  guru  di  Indonesia  masih  sedikit,  salah  satunya  “Lesson study”, namun jumlah komunitas ini tidak begitu banyak, Oleh karena itu untuk mengetahui berbagai bentuk relfeksi guru yang ada di Indonesia diperlukan suatau  penelitian  untuk  memetakan  kondisi  tersebut.  Penelitian  ini  adalah Review Reasearch dengan objek berbagai artikel hasil penelitian di Indonesia yang meneliti tentang “refleksi” guru dalam pembelajaran. Berdasarkan hasil review   artikel   penelitian   diperoleh   banwa   bentuk-bentuk   refleksi   yang dilakukan  guru  di  Indonesia  berupa:  jurnal  reflksi,  refleksi  wawancara, konfrensi observasi temanejawat, diskusi group, Video, Blok, dan portofolio elektronik. Kata Kunci : Refleksi, Pembelajaran
