Abstract

Abstrak Ikatan antara translokator protein (TSPO) dari Rhodobacter sphaeroides (RsTSPO) dengan hemin dalam dua detergen yang berbeda yaitu n-dodecyl-ß-D-maltoside (DDM) and n-dodecylphosphocholine (DPC) detergents telah diteliti. RsTSPO dipilih sebagai model untuk TSPO mamalia. RsTSPO di tanam dalam E.coli kemudian dieksraksi menggunakan buffer Tris pH 7,5 dan diikuti dengan pemurnian menggunakan Fast Protein Liquid Chromotography (FPLC). Hasil fluoresensi triptofan intrinsik menunjukkan bahwa RsTSPO memiliki afinitas terhadap hemin yang lebih tinggi dalam DDM (Kd = 0.35 µM) dibandingkan DPC (Kd = 0.575 µM) Kata kunci : translokator protein, hemin, fluoresensi, ikatan

Abstract

This study aims to look at the effect of the flipped classroom approach on the guided inquiry model and student's self-efficacy on creative thinking skills on the reaction rate material. The study was conducted in class XI MIA SMA N 3 Jambi City with a 2 x 2 factorial design and the sample consisted of 2 classes chosen randomly. Data collection using test techniques, namely essay tests, includes indicators of creative thinking and non-tests, namely self-efficacy questionnaire data and field notes during the study. Analysis of the data used is 2-way ANOVA. The results showed that guided inquiry learning with the flipped classroom approach and high self-efficacy categories had high creative thinking abilities, but there is no interaction between learning models with self-efficacy towards creative thinking abilities on the reaction rate material because learning models and self-efficacy affect the results of students' creative thinking abilities independently. Based on the results of the study it can be concluded: (1) There is an influence of the flipped classroom approach on the guided inquiry model of students 'creative thinking abilities on the reaction rate material (2) There is an effect of students' self-efficacy on the ability to think creatively on the material reaction rate (3) There was no interaction between the learning model and students' self-efficacy.Keywords: Creative thinking skills, Flipped classroom, Guided inquiry, Reaction rate, Self-efficacy

Abstract

Research on the development of comic-based student activity worksheets (LKPD) with a 4C approach (Critical Thinking, Collaboration, Creativity and Communication) on chemical equilibrium material for high school is an innovation in the development of teaching materials in order to achieve the demands of 21st century learning that facilitates and inspire students to be able to think critically, communicatively, creatively, innovatively, and collaboratively. The study was designed using research and development design (R & D) with a 4-D development model. The validation sheet and user response questionnaire are research instruments designed and then analyzed and produce data in the form of assessment and suggestions by the validator team, teacher respondents and students. Feasibility aspects of content, language, presentation, graphics, and characteristics of comics with a 4C approach with an overall percentage score of 93% by the material validator. The results of the percentage of users by teachers are 95% and the percentage of students is 88% with very good criteria. Based on the data analysis, it can be concluded that student activities worksheets based on comics with a 4C approach that produced is valid and can be used on Senior High School on chemical equilibrium material.Keywords:Chemical equilibrium; student activities sheet based comics with 4C approach; 4-D development model

Abstract

AbstractObesity is a global epidemiology and serious healthy treat due to morbidity and mortality raised. On the whole of the adult population in the world get obese 7.7% in men and 11.9% in women. Adipose tissue accumulates on obesity functioning as endocrine gland secrets all sitokin and peptide hormones. The secretion of those sitokin and hormones play role in controlling body weight balancing and energy metabolism. Resistin an adipositokin (adipokin) secreted by  adiposit that assumes to have important role as circuit between adiposity and insulin resistance. Physical exercises could influence resistin levels and blood sugar on obesity. This research aims to identify the influence of physical exercises ((healthy heart gym) of resistin and blood sugar levels on obesity. The design of this research uses purposive sampling. The subject of the study 25 female students of 18-21 years of age of Poltekkes Nutrition Department Kemenkes Aceh. Gymnastic exercise program done with a healthy heart with a frequency of 5 times a week for 4 weeks with intensity 30 minutes. The result of pre and post resistin levels checked is analyzed both descriptively and inferentially by t test and correlation (moment/pearson).   The result of t test of and correlation found that; there is no influence physical exercises toward resistin levels at the people with obesity (p= 0, 45), there is influence physical exercises (healthy heart gym) toward blood sugar levels of the people with obesity. (p=0, 03), there is no significant influences between resistin levels and blood sugar levels of the people with obesity in pre and posttest (p=0, 26). Based on the finding above, we may conclude that the physical exercises (healthy heart gym) influences toward blood sugar levels, but it doesn’t toward resistin levels.Keywords : Obesity, Resistin, blood sugar levels, physical exercises (healthy heart gym)

Abstract

Environmental pollution caused by waste is pollution that very dangerous for living things. In particular, water pollution, waste that is disposed of through waterways will disrupt the water ecosystem which will have an impact on human life. On the other hand, the development of entrepreneurship such as home industry has a positive impact on society, especially in terms of the economy. Therefore, water pollution indicators are needed that can be used as guidelines in treating wastes such as BOD and COD. In this study, analyzed the levels of BOD and COD from home industry wastewater in the Cawang area. The home industry includes laundry, cracker business, restaurants, printing houses, photocopying, and snack businesses. Based on the results of data analysis, the highest BOD level was 45.827 in samples taken at night. And, the highest COD levels were 95.923 in samples taken at night. These data indicate that the levels of BOD and COD in the water in the home industry waste disposal sites are below the standard threshold for wastewater quality. The levels of BOD and COD are in the safe category for aquatic biota.Keywords: BOD levels, COD levels, Waste, Water pollution

Abstract

AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Contextual Teaching and Learning (CTL) terhadap hasil belajar siswa dalam pembelajaran kimia pada pokok bahasan sistem koloid. Penelitian ini telah dilakukan di SMA Methodist 1 Medan. Kelas sampel (kelas XI) diberikan perlakuan dengan model pembelajaran CTL. Kelas sampel telah memenuhi kriteria uji normalitas dan homogenitas. Evaluasi awal(pre-tes) siswa kelas sampel rata-rata M=16.25±6.25. Setelah perlakukan pembelajaran menggunakan model CTL, rata-rata pencapaian siswa (post-tes) meningkat menjadi M=76.39±6.09. Meningkatnya rata-rata post-tes siswa tersebut mengindikasikan bahwa pembelajaran menggunakan model CTL dapat meningkatkan hasil belajar siswa. Keberhasilan belajar ditandai dengan peningkatan hasil belajar siswa, dimana dalam perhitungan keberhasilan belajar berdasarkan %gain diperoleh rata-rata keberhasilan siswa sebesar 72% Hasil analisis uji beda atau uji t diperoleh thitung > ttabel (6,34> 1,6905) pada α = 0,05 yang berarti pembelajaran menggunakan CTL berpengaruh positif terhadap siswa dalam meningkatkan hasil belajarnya pada pokok bahasan sistem koloid.Kata Kunci: Pembelajaran CTL, sistem koloid, hasil belajar siswa
