Abstract

Science is one of the subjects of National Standard School Final Examination (UASBN) in SD/MI, hence the learning achievement of the subject determines the students’ graduation. UASBN topics are taken from fourth until sixth grade materials so that science learning achievement of fourth grader needs more attention. But the fact is, based on the data of fourth grader in SDN ‘X’ Yogyakarta, the average value for science is sequence to 9 of 11 subjects. Besides, the science average value is still lower than the minimum criteria for completeness (KKM) of science. For years, the method developing in school is the conventional method (Kumara, 2004; Brahim, 2007; Depdiknas, 2008), whereas science is a subject which needs skill of understanding, analyzing, and relating a phenomenon with other phenomenon (Depdiknas, 2007). The purpose of this research is to examine the capability of Menggambar-Menceritakan Gambar method to improve the fourth grader’s science learning achievement. This research used a quasi experimental method with an “untreated control group design with pretest and posttest“. Science test was given for pretest and posttest. The intervention was applied for 10 sessions (3 sessions a week), which was held in 75 minutes. There were 32 partisipants, divided into two groups, experimental group (n=22) and control group (n=10). The data was analyzed by T-test. The gain-score was used for the analysis. The result of independent sample t-test analysis showed the differences in science learning achievement between experimental and control group (t=3,878; p<0,01), while the results of paired sample t-test analysis showed a difference between pretest and posttest scores of the experimental group (t=-9.298, p<0.01). These results indicate that Menggambar-Menceritakan Gambar method could improve fourth grader’s science learning achievement. Keywords: Menggambar-Menceritakan Gambar method, science learning achievement, fourth grader

Abstract

Abstrak Minat terhadap pelajaran dan motivasi belajar merupakan faktor penting yang turut menentukan hasil belajar seseorang. Oleh karena itu, upaya pengembangan minat dan motivasi sangat perlu mendapat perhatian dalam proses pembelajaran. Penelitian ini telah dilakukan dengan tujuan untuk menguji pengaruh penerapan perangkat pembelajaran berbasis inkuiri (PPBI) dengan strategi kooperatif pada peningkatan minat terhadap biologi dan motivasi belajar siswa SMA di kota Mataram. Penelitian dilaksanakan dalam seting eksperimental semu dengan ran­cangan faktorial 2 x 2. Data penelitian dianalisis dengan teknik anakova. Hasil penelitian menunjukkan bahwa PPBI berpengaruh positif pada minat terhadap biologi dan motivasi belajar siswa (F= 22,1 dan 7,9). Strategi kooperatif juga memberikan pengaruh positif pada minat dan motivasi siswa (F = 21,23 dan 6,24). Minat terhadap biologi dan motivasi belajar siswa melalui strategi kooperatif STAD berbeda dengan siswa yang belajar melalui TGT (p≤0,05). Interaksi PPBI dengan strategi kooperatif berpengaruh signifikan pada minat siswa terhadap biologi (F=16,19) tetapi tidak berpengaruh nyata pada peningkatan motivasi belajar siswa. Kesimpulan dari penelitian ini adalah bahwa implementasi PPBI dengan strategi kooperatif memberikan pengaruh positif pada perkembangan minat terhadap biologi dan motivasi belajar siswa.   Kata kunci: PPBI, STAD, TGT, minat terhadap biologi, motivasi belajar

Abstract

Proboscis monkey (Nasalislarvatus) is a species of primates endemic in Borneo. According to South Borneo Governor's Decree No. 29 Year 1990 dated January 16 at1990, proboscis monkey is set to be a mascot fauna of South Borneo Province. The habitat of proboscis monkeys are usually found along the rivers and swamp areas in Borneo. Research of proboscis monkeys who live in mountainous areas are still very rarely done so little known by the public. Therefore , to determine the condition of proboscis monkeys in a habitat of them to do research on the structure of the population. The purpose of this study was to calculate the number , density and age structure of the population pyramid illustrates the proboscis monkey (Nasalislarvatus). The method used is descriptive method by calculating the concentration technique (concentration count). The study was conducted on a population proboscis monkey (Nasalislarvatus)  in the area of BatuSawar Mount in Hulu Sungai Tengah District. Data analysis was performed by direct calculation during primate visible. The largest number of individuals encountered on a whole series of observations is assumed as the number of individuals that represent a group, whereas the smallest number of individuals encountered is assumed that the other individual is not visible at the time of observation.The observation of the proboscis monkeys (Nasalislarvatus) found in the area of research were adult proboscis monkey amounted to 17 with a density of 0,028 ind / ha, totaling 23 juveniles proboscis monkey with a density of 0.038 ind / ha, and child proboscis monkey amounted to 13 with a density of 0,022 ind / ha.

Abstract

Tagetes erecta is an annual plant that is, in addition, to be used as an ornamental plant, it can also be used as an agent for phytoremediation. Glomus intraradices is one of the species of vesicular-arbuscular mycorrhizal (VAM) fungi which can be mutually symbiotic with various species of plants, including T. erecta.  This study was aimed to determine the effect of VAM fungi G. intraradices on the growth of T. erecta in growth media containing chromium. The study was carried out experimentally using a completely randomized design with treatments, namely Cr6+ concentrations of 0, 5 and 10 ppm in the form of K2CrO7, and the addition of VAM fungi G. intraradices in the growth media in the form of soil and mixture of soil: textile sludge (1: 1).  T. erecta was grown in four different growth media (soil, soil: textile sludge (1:1), soil+VAM, soil: textile sludge (1:1)+VAM) that was treated with Cr6+ and G. intraradices for 1.5 months. The growth of T. erecta was determined based on plant height, root length, root dry weight, shoot dry weight, and percentage of mycorrhizal infection. Data were analyzed with two-way Analysis of Variance (two-way ANOVA) and DMRT (Duncan's Multiple Range Test) with a test level of 5%. The results showed that the growth of T. erecta in media containing Cr6+ (5 and 10 ppm) decreased significantly compared to controls (without Cr6+ treatment).  The highest reduction of plant growth was found in media containing Cr6+ of 10 ppm. The addition of VAM fungi G. intraradices in soil media and soil: textile sludge that treated with Cr6+ was able to increase the growth of T. erecta. These results indicated that the VAM fungi G. intraradices were able to improve the ability of T. erecta to deal with chromium heavy metal stress. That results were also supported by the percentage of mycorrhizal infection in the roots of T. erecta grown in soil and soil: textile sludge (1:1) media with treatments of Cr6+ and VAM G. intraradices were higher than the control plants that was grown in soil and soil: textile sludge (1:1) media without treatments of Cr6+ and VAM G. intraradices.
