No full textResearch on diversity and composition of fish at low tide and high tide condition in downstream Kelay River, District Berau, East Kalimantan is not yet know. The purpose of this research was to determine diversity and composition of fish that present at low tide and high tide condition in downstream Kelay River. In research using purposive sampling method and various sizes gill nets used. Results of this research shows that fish were collected at three locations sampling in downstream Kelay River consist of 14 species, 9 families, and 953 individuals. Based on the number of species, diversity Shannon-Wiener index and dominance index has stable of communities, with high value of diversity index (H'=1.975), high evenness index (E=0.749), and low value of dominance index (D= 0.173). The number of fish species found at low tide were 11 species and at high tide were 12 species. The similarity index of fish species at low tide and high tide condition were 64.3%
NILAI RUJUKAN UNTUK EVALUASI FUNGSI HATI DAN GINJAL PADA TIKUS (Rattus norvegicus Berkenhout, 1769) GALUR WISTAR
Full text linkEvaluation of liver and renal functions are routine tests performed in preclinical studies. Liver plays a role in detoxification and secretion of various substances to regulate a wide range of metabolic functions. Kidneys serves as the main excretory and osmoregulatory organs. Thus, assessment of liver and renal functions are important in identifying the presence of damages and diseases as well as monitoring body responses towards treatments or therapy. Therefore, normal values should be established for valid reference. Until now, many researchers still use references from various publications, including foreign countries with different environmental factors and method of animals care. This study was aimed to provide reference values for liver and renal functions in male and female Wistar rats. Animals were sourced from LPPT-UGM. Age 4-, 6-, and 8-week-old represent juvenile, preadult, and adult. Blood samples were collected from orbital sinus of anesthetized animals. Sera were tested for ALT, AST, BUN, and creatinine based on spectrophotometry. Results demonstrated that values of most parameters varied, depend on sex and age. According to this finding, it can be concluded that reference values cannot be generalized but must be determined by sex and age in local population
HISTOLOGI JARINGAN MANTEL TIRAM (SAIBO) PADA BEBERAPA JENIS BIVALVIA SEBAGAI ALTERNATIF IMPLANTASI MUTIARA
Full text linkAll types of bivalves have the potential to produce pearls. Pearls can be produced naturally and cultivated. In cultured pearls, pearl sac are obtained from saibo (slices of another bivalve mantle) that which come from pallial zone. This study wants know the structures of tissues saibo of several species of bivalves as an alternative pearls implantation. This study is conducted from January to March 2017. This study used 7 types of bivalves among others; Pinctada margaritifera, Saccostrea cucullata, Asaphis violascens, Polymesoda bengalensis, Pinna muricata, Volachlamys singaporina, and Tridacna crocea. The method used by staining Hematoxylin-Eosin. Thisstudy show results that every saibo has the different characteristic, but has a common characteristic of having outer epithelium mantle, inner epithelium mantle, muscle fibers, connective tissue and longitudinal muscle, so it can be recommended in pearls implantation Keywords : Saibo, Bivalvia, Implantasi Mutiara[H1] [H1]Disusun berdasarkan abja

PENGEMBANGAN KOMPETENSI SIKAP DALAM PEMBELAJARAN MATEMATIKA SECARA HOLISTIK BERSUMBER QUR’AN
Full text linkAbstractThis study aims to describe the process of developing spiritual and social attitudes competencies, in a holistic learning of mathematics sourced in the Qur'an. Qualitative research is applied in the preparation of teaching materials based on the integration of core competencies of revised Curriculum-13, and the development of attitude competencies in mathematics learning based on the Qur'anic. The subjects of the study were SMP / MTs students in the lessons of Straight Line Equation. The research data includes documents, learning recordings, and interviews, and it’s analyzed using the Miles & Huberman Method. The study resulted in: (1) mathematics teaching materials on the topic of the Straight Line Equations sourced of the Qur'anic (al Anfal) verses 65-66, to teach holistically, (2) The process of developing competency attitudes is carried out as long as the learning takes place from introduction to closing the lesson. In developing a spiritual attitude, two students are assigned to read the verses of the Qur’an and their translations, then discuss the content of mathematics. Students are aroused by curiosity with questions about verse, working collaboratively with friends, choosing the best ideas (tolerant), and being responsible for completing tasks. In developing skills and knowledge competencies, students are guided to achieve the process of modeling problems related to the Qur'anic verses, so that they find problem solving procedures, or mathematical concepts from the topics studied.Keywords: attitude competency development, holistic mathematics learning.

No full textAbstractThis study aims to determine the improvement of students' thinking skills through the Earth and Space Science (IPBA) lectures that integrate science activities with interactive multimedia and local science. The research method used was experimental design (quasy experiment) with comparative group of pretest-posttest group design. Data collection techniques that will be done are measurement techniques in the form of students' thinking skills tests and surveys in the form of student and lecturer responses to the lectures are held. Physics education student semester 4 academic year 2016/2017 will participate as research subject. The results showed that the increase (N-gain) of students' thinking skill in experimental class was 0,70 and control class was 0,40 (both medium category). By using Paired Sample Test obtained tcount = 8,338 at significance level P = 0,000. The significance level is less than 0.05 (P <α), so it can be concluded that the application of lectures that integrate local science and technology in IPBA lectures can improve students' thinking skills significantly compared with conventional lectures.Keywords: high order thinking skills, earth and space science, multimedia interaktif.
