PEMAHAMAN KONSEP DAN MISKONSEPSI MAHASISWA CALON GURU PADA HUKUM KEPLERAbstrakPenelitian ini bertujuan untuk menginvestigasi tingkat pemahaman konsep dan miskonsepsi mahasiswa calon guru pada hukum Kepler. Subjek penelitian adalah 68 mahasiswa peserta mata kuliah Ilmu Pengetahuan Bumi dan Antariksa (IPBA). Sampel dipilih berdasarkan teknik persampelan purposif. Pengumpulan dan analisis data menggunakan mix method, gabungan penelitian kuantitatif dan kualitatif. Instrumen yang digunakan adalah two-tear test berupa penyusunan peringkat dan pemberian alasan. Analisis dilakukan terhadap dua lapis data yang dianalisis secara bersamaan berdasarkan tingkat pemahaman konseptual. Hasil penelitian menunjukkan tingkat pemahaman konsep bervariasi dengan dominasi Paham Sebagian dan Miskonsepsi (33,82%) untuk Hukum II Kepler dan Paham Sebagian (42,65%) untuk Hukum III Kepler. Penelitian mendapatkan 14 bentuk miskonsepsi berkaitan dengan kecepatan, perioda, dan jarak orbit benda langit mengitari bintangnya dan pengaruh massa serta bentuk orbit ter-hadap variabel kecepatan, perioda, dan jarak orbit. Sebelas miskonsepsi belum dilaporkan pada penelitian sebelumnya. Pembelajaran tradisional tidak berhasil dalam meningkatkan pemahaman konsep karena berorientasi pada penguasaan rumus dan penghafalan fakta. Perlu inovasi pembelajaran untuk meningkatkan penguasaan konsep.Kata kunci: pemahaman konsep, miskonsepsi, hukum Kepler, IPBAAbstractThis study was aimed at investigating the level of understanding of the concepts and misconceptions of teacher students in Kepler's law. The research subjects were 68 students participating in the Earth and Space Sciences (ESS) course. The sample was chosen based on the purposive sampling technique. The collection and analysis of the data used a mixed-method, a combination of quantitative and qualitative research. The instrument used was a two-tear test in the form of ranking and explanation. The analysis was carried out on two layers of data which were then analyzed simultaneously based on an analysis of the level of conceptual understanding. The results show that the level of concept understanding varied with the dominance of Partial Understanding and Misconception (33.82%) for Kepler's Law II and Partial Understanding (42.65%) for Kepler's Law III. The study found 14 forms of misconception related to the velocity, period, and orbital distance of celestial bodies around the star and the effect of mass and orbital shape on variable velocity, period, and orbital distance. Eleven misconceptions have not been reported in previous studies. The failure of conventional learning in improving understanding of concepts is due to the application of traditional approaches that are oriented towards mastering formulas and memorizing facts. Learning innovation is needed to improve the mastery of concepts.

The Temple

In the period 4800-3600 BC. in the eastern part of the Trypillia area arose "giant settlements" or "megasites" / "mega-settlements" (working term of modern archaeologists) with thousands of buildings. In the central parts of these living conglomerates, scientists found special buildings that were recognized as sanctuaries, sacred complexes or temples. In the late period of the Trypillia culture they disappeared. These religious buildings were built with a focus visible processes of celestial bodies and the laws of cyclic rotation of the Earth in space, and included in their internal filling usually cruciform altars, ritual utensils, troughs with graters for the preparation of ritual bread and numerous other ceremonial and religious artifacts. There were also unique finds, such as gold jewelry (an element of prestige) and a perforated clay disk with tockins to it from the space of the Nebelivka Temple. The interior and exterior walls of the Trypillia sacral centers were painted with natural colors with a predominance of red. The wood carving for decoration of elements of a skeleton of a construction was investigated also. The first Temples on the European continent show that even at that time there was a cult of architecture. In general, it is clear that such Trypillia objects of religious worship carried encoded astronomical information in symbolic form. The building itself was oriented with regard to worldsides and designed relative to visible celestial bodies. This indicates that the people of Trypillia had a fairly clear worldview, which allowed them to reach the level of understanding the structure and mechanisms of many natural cyclical processes on Earth. Trypillia cosmology united the celestial and terrestrial spheres, and the Temple was the point of contact of the earth with the visible Universe. In his work, the author traces the existing analogies in the structure of construction of Trypillia and sacred complexes of the ancient Middle East and biblical ideas about the Tabernacle and the House of the Lord in the ancient Jews, given the fact, that the Trypillia temple building is known from 4,000 years BC. and several thousand years older than the Middle Eastern counterparts. There are also significant parallels in the construction of temples in the context of Indo-European religious heritage. It is noted that the Temple was not only a metaphysical reflection of the annual cycle with a focus on the points of the equinoxes and solstices, but also had a higher religious function, which consisted in the combination of the terrestrial sphere with the celestial, the connection of man with the mystery of the cosmos.

Among the celestial bodies the sun is certainly the first which should attract our notice. It is a fountain of light that illuminates the world! it is the cause of that heat which main­tains the productive power of nature, and makes the earth a fit habitation for man! it is the central body of the planetary system; and what renders a knowledge of its nature still more interesting to us is, that the numberless stars which compose the universe, appear, by the strictest analogy, to be similar bodies. Their innate light is so intense, that it reaches the eye of the observer from the remotest regions of space, and forcibly claims his notice. Now, if we are convinced that an inquiry into the nature and properties of the sun is highly worthy of our notice, we may also with great satisfaction reflect on the considerable progress that has already been made in our knowledge of this eminent body. It would require a long detail to enumerate all the various discoveries which have been made on this subject; I shall, therefore, content myself with giving only the most capital of them.

Background: The first labor anxiety is an unpleasant psychological condition due to physiological changes that cause psychological instability. The condition of excessive anxiety, worry, fear without cause, and stress, causes the muscles of the body to tense up, especially the muscles in the birth path to become stiff and hard, making it difficult to expand. This study analyzed the effect of pregnancy exercise on third trimester primigravida anxiety in dealing with childbirth. Methods: Quasi experimental design with nonrandomized pretest-postest control group. The sampling technique used was purposive sampling with 34 research subjects. 17 people for the treatment group were given pregnancy exercise 8 times, and 17 people for the control group were given health education about preparation for childbirth. Results: The results of data analysis using the Wilcoxon signed rank test showed that the average reduction in the treatment group was 8.00 and the control group was 3.00. The effect of pregnancy exercise on third trimester primigravida anxiety in the treatment group with a p-value (0.000) <(0.05), while the control group with a p-value (0.180)> (0.05). Conclusion: There is an effect of pregnancy exercise on third trimester primigravida anxiety in dealing with childbirth in the Wuryantoro Health Center work area.
