Abstract

Abstrak. Udara atmosfer norrnal yang kering adalah campuran gas-gas yang mengandung sekitar 79% Nitrogen (N2) dan 2l% oksigen (O2). Manusia bernapas sekitar 6 liter (6x10-3m3)  udara agar mendapatkan pasokan oksigen (O2) segar kedalam paru dan membuang karbon dioksida (CO2). Ketika kita menghembus napas alveoli menjadi lebih kecil. Pertukaran gas (O2 dan CO2) antara alveoli dan darah terjadi melalui difusi yang menyebarkan O2 dari alveoli kedalam darah dan CO2 dari darah ke alveoli. Perbedaan tekanan O2 dan CO2 di jaringan mempengaruhi transpor gas-gas melewati dinding alveolus, molekul O2 berdifusi lebih cepat dari pada molekul CO2 karena massanya lebih kecil. Apabila terdapat penyakit yang menyebabkan dinding alveolus menebal transpor O2 akan lebih ternganggu dibandingkan dengan transpor  CO2. Abstract. Normal dry afinospheric air is a mixture of gases containirtg about 97% Nitrogen (N2) And 21% oxygen (O2). Humans breathe approximately 6 quarts (6x10-3m3); of air, in order to get a supply of oxygen (O2) into the fresh pulmonary and dispose of carbon dioxide (CO2). When we exhale breath alveoli become smaller. Gas exchange (O2 and CO2) between the alveoli and the blood occrrrs by diffusion which spread frorn the alveoli into the blood O2  and CO2 from the blood irrto the alveoli. O2 and CO2 pressure differences in the network affects the hanspon of gases through the alveolar walls, O2  molecules diffuse faster than molecules of CO2: because its mass is smaller. If there is a disease that causeslthickefied alveolar walls O2 transport would be more disturbed than the transport of CO2.

Abstract

Abstrak. Beraktivitas dalam jarak dekat merupakan salah satu faktor resiko (efek) terjadinya miopia, semakin lama seseorang memfokuskan penglihatannya untuk melihat dekat semakin lama pula mata seseorang melakukan akomodasi, sehingga lama kelamaan mata akan lelah dan kondisi ini akan memicu pengaburan di retina dan mata menjadi tidak fokus. Miopia adalah suatu bentuk kelainan refraksi dimana sinar sejajar yang datang dari jarak tak terhingga oleh mata yang dalam keadaan tidak berakomodasi dibiaskan pada satu titik didepan retina, penglihatan jauh kabur, maka miopia merupakan penyebab utama gangguan penglihatan. Abstract. Eye is one of the human sensory organs that has the function to look. Someone’s vision is really determined by a light refraction inside the eyes, a vision media consisting of cornea, eye liquid, lens, glass lens and length of eye-ball. Refraction anomaly is one of the blindness causes in the world. Refraction anomaly is a ray refraction on eyes so that the ray is not focused on the retina or fovea, but in the front of or behind the fovea and perhaps it is not located on one focus point; if there is a light refraction anomaly inside the eyes, the observed objects are less clear (sightedness) caused by a light point that is not precised in retina (a light which is not focused in the retina), there are three types of a refraction anomaly, myopia, hyperopia, and astigmatism.

Abstract

Abstrak. Kebiasaan merokok merupakan prilaku yang dapat mengakibatkan dampak negatif  bagi kesehatan tubuh seseorang, yaitu dapat menyebabkan perubahan struktur, fungsi saluran pernapasan dan jaringan paru. Asap  rokok mengandung susunan senyawa gas dan partikel seperti karbon dioksida, air, karbon monoksida, partikular (kebanyakan tar), nikotin, nirtogen oksida, hidrogen sianida, amoniak, formaldehida, fenol dan puluhan lainnya senyawa beracun terkenal. Saluran pernapasan adalah bagian tubuh manusia yang berfungsi sebagai tempat lintasan dan tempat pertukaran gas yang diperlukan untuk proses pernapasan, jika ada asap rokok maka mudah terjadi obstruksi jalan napas yang dapat mengakibatkan sesak napas.Abstract. The smoking habit is a behaviour which can cause a negative impact for someone’s body helath, particularly it causes a stucture change, an airway function and a lung biopsy. A smoke consists of a gas compound structure and particle, such as carbon dioxide, water, carbon monoxide and particular (mostly tar), nicotine, nitrogene, oxide, hydrogen cyanide, ammonia, formaldehyde, pheno and other tens of poisonous famous compounds. An airway is a part of the human body which has a function to be a place for the passage and the gas exchange which are needed for a breathing process, so that if there is a smoke, the airway obstruction occurs easily which causes a short of breath.

Abstract

This study aims to determine the effect of the application of PBL models of science process skills (PPP) and the understanding of the concept of chemical substances in food at eighth grade students MTsN Meureudu. This study is a descriptive study using the research design one group pretest and posttest design. Samples were 19 eighth grade students MTsN Meureudu school year 2013/2014. Data collected by pretest and posttest to determine the effect of the application of PBL models and observation sheets to determine the feasibility of learning. The results showed that affects the application of PBL model of PPP and understanding the concept of chemical substances in food MTsN Meureudu eighth grade students. The influence can be seen from the results of hypothesis testing, the value is significantly smaller than α (0.05). In addition, the ability of a class VIII student representation MTsN Meureudu after application of PBL models on chemical substances in food material for the better. The ability of the student representation on enactive is 74%, 63% iconic, and symbolic 68%.

Abstract

One of the factors of low student learning outcomes on physic learning coursed lack of ability teachers in effecting the pedagogic practice and knowing subject matter in the learning environment. Pedagogical content knowledge (PCK) is the blending of pedagogical knowledge and content knowledge which must have by teachers in realizing learning objectives. This research aims to showed the implementation pedagogical content knowledge (PCK) of physic teacher based on students learning outcomes on measurement and magnitude material at class of X IA4 SMAN 4 Banda Aceh. Outcomes of this research are: the average value of students learning outcomes is 80 with description the PCK of physic teacher are 95% teacher have understood students of characteristics in learning process, 67% teacher success in planning of learning, 70% teacher success in implementing learning activities, 67% teacher success in evaluating learning outcomes, 75% teacher has been able developing the potentials of the students, and 75% teacher has mastered the science of substances.

Abstract

This research aims to examine the improvement of mathematical communication skills of the students who learn using the team quiz learning model. This is an experimental research with pretest-posttest-control group design. The population of this study is all of the seventh-grade students in one of the junior high schools in Banda Aceh. We use a simple random sampling technique to obtain two classes as the research samples. The data were collected using tests of mathematical communication skills and self-efficacy questionnaires. The statistical tests used in this study were the paired t-test and two-way ANOVA. The results show that: (1) The improvement of the students’ mathematical communication ability in the team quiz class is higher than the conventional class; (2) The improvement of the students’ self-efficacy in team quiz class is higher than the conventional class; (3) There is no interaction between the learning model and the student level towards the students' mathematical communication ability; and (4) There is no interaction between the learning model and the student level towards the students’ self-efficacy.
