Penerapan Conceptual Change Text Berbantuan Phet Simulation Untuk Meremediasi Miskonsepsi Fluida Dinamis Di SMA

In this study, the effect of conceptual change text (CCT) with PhET simulation to remediate students' misconceptions of fluid dynamic at SMA was investigated. Quasi-experimental with non-equivalent control group design was used which involved 62 eleventh grade students. This study was made of into two groups. Experimental group (N=29) were given CCT with PhET simulation, whereas the control group (N=33) were given re-test. Nine open-ended multiple-choice questions concerning fluid dynamic were used as data collection tool. The results showed experimental group's average of decreasing students' misconceptions (59,58%) were higher than control group (15,57%), and caused differences between both of groups that were proved by two-sample proportions test, Zscore (2,08) > Ztable (1,96). In the other hand, decreasing quantity of that misconception (DQM) value showed CCT with PhET simulation more effective than re-test to remediate students' misconceptions about fluid dynamic. It determined that CCT with PhET simulation could be alternative to remediate students' misconceptions

Potensi Gulma Rorippa Indica Sebagai Reservoar Parasitoid Hemiptarsinus Varicornis Untuk Mengendalikan Liriomyza Huidobrensis

Leafminers, Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) known as main pest at vegetable and ornamental crop. Hemiptarsinus varicornis (Girault) (Hymenoptera: Eulophidae) is one of ectoparasitoid larvae of L. huidobrensis that usually find in the field, however the levels of parasitism at field relative lower. Therefore we need the conservation technology of parasitoid in order to its population overflow so that its performance increases. Rorippa indica (L) have potential as reservoir of parasitoid H. varicornis, so that can be used as conservation medium of H. varicornis. Planting weeds R. indica among of chickpea crop, can decraese the population of adult and larvae L. huidobrensis significantly, increase adult population H. varicornis and larvae population L. huidobrensis parasitism by H. varicornis. Growth rate of population adult H. varicornis at block without weeds R. indica follow the pattern of regretion equation Y=0,1312X–0,2246 and Y=0,7172X+1,1 while at the block planted weeds R. indica. Growth rate of larvae population L. huidobrensis at block without weeds R. indica follow the pattern of regretion equation Y=0,9315X–0,9835 and Y=0,8647X+1,0875 while at the block planted weeds R. indica. Weeds R. indica can be used as reservoar parasitoid H. varicornis in the effort the conservation parasitoid

Penerapan Model Pembelajaran Sfe untuk Meningkatkan Hasil Belajar dan Aktivitas Fisika Siswa di SMA

This research aimed to: find out the increase of learning outcomes and student activities by applying the learning model of SFE (Student Facilitator and Explaining) on the ideal gas in the grade XI of Natural Science major of State Senior High School 1 Sungai Ambawang. This research was a classroom action research which consisted of two cycles with the the stages as follows: planning, action, observation and reflection. The subjects of this research were 28 students. The data were collected through observations and description tests. The results of observations showed that the student learning activities increased from the first to the second cycle, i.e. in the form of asking questions from 14.29% to 21.43%, answering questions from 17.86% to 21.43%, expressing opinions from 28.57% to 35.71%, and taking note/summarizing the teaching material from 96.43% to 100%. The results of the research indicated an average improvement of learning outcomes in the first cycle by 36.39 with a completeness of 78.57%, and in the second cycle by 58.53 with a completeness of 85.71%

Pasang Surut Hubungan Islam-barat

This paper is a literature review (literature research) that uses John Esposito's books as primary data sources and other figures' statements about the relationship between Islam and the West as its secondary data source. The method of analyzing data used descriptive, interpretative, and analytical methods. The findings of this research are: first, based on historical fact, there is strong theological bond between Islam and the West, i.e. there are common ground and similarities between Islam and the West who inherited the Jewish and Christian traditions. These three religions inherited the tradition of Prophet Ibrahim. However, existing theological equation between Christianity and Islam became the cause of the collision between the two. Second, the historical problems between Islam and the West can be seen from the root of the conflicts, which include theological and political ones. Conflict between Islam and the West are covered with political motives. In contrast, religion is only used as a theological justification to culturally and theologically distinguish Islam and the West. Basically the difference is more driven by political interests. Third, as an effort to build a global coalition agreement, both sides should actively promote cooperation. Therefore, the most important thing is that the meet between Islam and the West should be interpreted as a civilization dialogue, not confrontation or distrust. the Building ideal relationship as well as the need for harmonization between Islam and Western civilization are also needed

Mengatasi Hambatan Berhitung Mencongak Menggunakan Strategi Mental dalam Materi Operasi Bilangan Bulat

This iams of this research is to overcome the obstacles arithmatic computation students use mental strategies in the material addition and subtractionof integers. The method used in this research is descriftive researh. The subjects consist of 9 student on grade VII SMP N 4 Sintang. The subjects were given three meeting treatment on mental strategies that Aggregation, Wholistic, Separation and separation left to right. Before being given the students mental strategies many obstacles arithmetic computation as, amounting to 77,8% of students still rely on stationery and using the standard way, by 43,2% students are taken more than 15 seconds to answer a question and 30,2 % of student answered incorrecly or not answered at all. After given a mental strategy aritmetic computation the students better than, no longer rely stationery and paper by 10% of studets take more than 15 seconds to answer question and only 6,7% of students incorrecly
