Abstract

Kepribadian merupakan sifat hakiki individu yang tercermin pada sikap peserta didik. Keunikan tersebut tergantung pada tipe kepribadian yang dimiliki.Tipe kepribadian tersebut mempengaruhi sikap dalam menyesuaikan diri dan bersosialisasi dengan lingkungan, termasuk dalam proses pembelajaran. Sikap belajar adalah kecenderungan perilaku saat mempelajari yang bersifat akademik dan merupakan salah satu faktor yang mempengaruhi hasil belajar. Sikap terkadang didasari oleh emosi dan dorongan dari dalam diri, dengan dorongan yang baik maka akan menghasikan sikap belajar yang baik pula dan begitu pula sebaliknya. Penelitian ini bertujuan untuk mengetahui perbedaan sikap belajar matematika siswa berdasarkan tipe kepribadian di SMA Islam Al-Azhar 5 Cirebon. Pendekatan yang digunakan dalam penelitian yakni kuantitatif dengan metode deskriptif. Populasi dalam penelitian ini adalah siswa SMA Islam Al-Azhar 5 Cirebon, sedangkan sampelnya adalah siswa kelas X berjumlah 98 orang. Teknik sampling yang digunakan dalam penelitian ini adalah probability sampling dengan menggunakan simple random sampling. Berdasarkan hasil analisis yang telah dilakukan bahwa tidak terdapat perbedaan sikap belajar matematika berdasarkan tipe kepribadian yang signifikan, hal ini dapat dilihat dari F­hitung hasil uji one way anova yang dilakukan lebih kecil dari Ftabel yaitu 0.616 dimana Ftabel­ nya adalah 2,7 maka H0 diterima artinya tidak terdapat perbedaan yang signifikan antara sikap belajar berdasarkan tipe kepribadian siswa.Kata kunci: Tipe Kepribadian, Sikap Belajar Matematika

Abstract

Mathematical textbooks are one source of learning that has an important role in learning activities. But the existence of the government-issued mathematics textbook (BSE) which is currently widely used in class X high schools, still does not know the quality of its cognitive aspects. The purpose of this study was to find out the questions contained in class X high school mathematics textbooks had met the criteria of a good question according to the Marzano cognitive aspects. Qualitative descriptive research was used to analyze competency test questions in mathematics books. Data was collected through a question categorization checklist based on Marzano's cognitive aspects validated by experts. Guidelines for question analysis based on Marzano's taxonomy's cognitive aspects consisted of levels of cognitive retrieval, levels of cognitive understanding, levels of cognitive analysis, and levels of cognitive knowledge. The results showed that the percentage of question distribution for the recall rate was 17%, at an understanding level of 14%, 30% analysis level, and 39% knowledge level; in other words, cognitive distribution in high school mathematics class X textbooks was still not ideal according to proportional allocation of aspects cognitive

Abstract

Melon (Cucumis melo L.) is a fruit commodity that gets a great interest to be developed in Indonesia and has a high nutritional value. However, the fungal infection and pathogens in melon cultivation are considered significant problems that are difficult to manage. Therefore, efforts are needed to improve the productivity and quality of melon and prevent pest and disease attacks. One mineral nutrient that is assumed to enhance plant resistance and increase the quality and production of melon is silica. The purpose of the research was to evaluate silica absorption from foliar-applied silicon nanoparticles in melon under soilless culture and improve melon fruit's growth and quality by applying silica fertilizer. The experimental design used was a split-plot randomized complete block design 3 x 2 factorial pattern with four replicates. The main plot factor is silica fertilizer (Novelgro, water-soluble), consisting of three silica concentrations of 0.67; 1.33 ppm, and control. The spray volume of each treatment was 160 ml per plant with seven days' intervals and a frequency of three times. The subplot factor is melon varieties consisting of “Alisha” and “Glamour”. The findings showed that silica fertilizer significantly increased the plant height, stem diameter, internode length, total number of hermaphrodite flowers, number of hermaphrodite flowers that are swelling, while decreased the fruit moisture content and gave the best average fruit position. Instead, The “Glamour” variety gave the best response to plant growth and fruit quality. Moreover, the melon plant could absorb silica in the low category (<1% Si). The highest silica contents were found in the “Alisha” cultivar leaves and the “Glamour” cultivar's rinds treated with the silica concentration of 1.33 ppm as much as 0.34% and 0.30%, respectively.

Abstract

The experiment was conducted to determine the activity of endogenous hormones in young seedless berry of Muscat of Alexandria (MOA) grapes induced by streptomycin (SM) and spectinomycin (SE). Young berries dipped in 200 ppm M or 200 ppm SE at 3 days before full-bloom and untreated berries were analyzed for the activity of . endogenous auxin, cytokinin. gibberellin and abscisic acid (ABA). The experiment was conducted at the Laboratory of ! Pomology, Faculty of Agriculture, Okayama University, Japan, from February 1999 to August 1999. Both SM and SE \treatments did not affect ABA activities of young berries. Cytokinin activity were slightly decreased by SM and SE treatments at 6 days after treatment (DAT) and became more severe at J 0 and J 3 DAT The response of berry auxin activity to antibiotic treatment was similar but stronger than cytokinins. Antibiotic treatments significantly decreased the activity ofGA at 6 and 10 DAT   1 Keywords,' Antibiotics, Endogenous hormones, Spectinomycin, Streptomycin

Abstract

Four kinds of antibiotics were examined, viz. streptomycin (SM) and gentamicin (GM) as bactericidal antibiotica and tetracycline (TC) and spectinomycin (SE) as bacteriostatical antibiotics. Kyoho an Pione (tetraploid hybris cultivars) were used as the plant materials. Among the four antibiotics, SM and SE were effective to induce seedlessness in Muscat of Alexandria (MOA) and less effective for Kyoho and Pione. The seedless induction effect of SM and SE seemed not to be affected by their mode of action. Using the four cultivars, Kyoho, Pione, MOA, and Neo Muscat (NM), either SM or SE most effective to induce seedlessness when applied 3 days before full bloom. The ineffectiveness of antibiotics for Kyoho and Pione was indicated by the higher percentage of empty-seeded berries in these cultivars compared to MOA and Nm. Since there was no normal seed in the antibiotic-treated berries, this phenomenon indicated that the outer parts of the tetraploid ovules were more resistant to antibiotic treatments than those of diploid ovules.   Key word: Grape, Seedless, Antibiotics

Abstract

The objective of the experiment was to investigate the physical and chemical characteristics of three stadia of maturity based on a range of peel color from green to yellow or based on percentage of the yellow area of fruit peel (stadium 1 = 25-49 % yellow, stadium 2 = 50-74 % yellow, and stadium 3 = above 75 % yellow) on six genotypes of papaya. Each genotype exhibited different days to maturity for each stadium. The fruits of stadium 1, 2 and 3 for IPB 1 were picked at 130, 135, and 140 days after anthesis (DAA); IPB 10A at 160, 165, and 170 DAA;  IPB 1 x PB 174 at 135, 140 and 145 DAA; while PB 174,  IPB 1 x IPB 10A and IPB 10A x PB 174 were picked at 140, 145 and 150 DAA, respectively. The results indicated that peel firmness was affected by maturity stage on female fruit of IPB 10A. Maturity stage affected chemical characteristics of papaya included total soluble solids (TSS) content (IPB 10A, female fruit of  PB 174, female fruit of IPB 1 x IPB 10A, and female fruit of IPB 1 x PB 174), vitamin C content (hermaphrodite fruit of 10 A, female fruit of IPB 1 x IPB 10A) and juice pH (hermaphrodite fruit of  IPB 1).  IPB 1 genotype can be harvested at all stadia of maturity stage. Hermaphrodite and female fruit of IPB 10 A, female fruit of  PB 174, female fruit of  IPB 1 x IPB 10A and female fruit of IPB 1 x  PB 174 genotype would be better harvested at stadium 3 of maturity stage.   Keywords: Carica papaya, papaya genotype, hermaphrodite fruit, female fruit, fruit quality, fruit maturity stage

Fruit characterization study is very useful for genotype improvement and genotype classifi cation of papaya. In this study the morphological characters of 36 genotypes were analyzed to determine their phenotypic variabilities. The relationships between genotypes based on all of the morphological and fruit characteristics were tested by subjecting the data to multivariate principal component analysis and to cluster analysis. Based on the dendrogram generated from vegetative and generative characters, the 36 genotypes could be grouped into 11 clusters on a threshold of 1.6 and formed 6 clusters on a threshold of 1.8. The dendrogram was able to explain the close relationship between IPB 5 x IPB 1 and IPB 5 x IPB 4, IPB 2 and IPB 7, IPB 1 and IPB 3 genotype. The scattered diagram of generative variable divided the papaya genotypes into three groups based on fruit sizes i.e small group (IPB 1, IPB 3, IPB 4, IPB 3 x IPB 4, IPB 1 x IPB 9), medium group (IPB 5, IPB 7, IPB 8, IPB 9) and big group (IPB 2, IPB 10). The IPB 1, IPB 3 and IPB 4 were different from IPB 2 in fruit shapes, petal length of male fl owers, infl orescence size and fruit length. The hybrid plants obtained from crossings with IPB 10 were different from the other genotypes in the colours of female-, hermaphrodite-, and male fl ower-lobes. Subsequently the scatter diagrams also revealed that several genotypes i.e. IPB 2 x IPB 6, IPB 1 x IPB 5, IPB 1 x IPB 9, IPB 5 x IPB 1 and IPB 5 x IPB 2 had superior characters ideotype similar to IPB 1, IPB 3 and IPB 8 genotypes.

Abstract

ABSTRACTThe improvement of Mangifera indica L. by conventional breeding approaches has been confounded by the long generation cycle, low fruit set, single seed per fruit and high degree of cross pollination. Biotechnology complements conventional breeding and expedite the mango improvement programs. Endosperm culture is a direct method to produce triploid plants. This study aimed  to obtain embryo from endosperm culture. The system of secondary somatic embriogenesis in mango described here represents a source of embryogenic material may be used for mass propagation and genetic manipulation of this crop. The method consisted of induction, proliferation, maturation, germination, and histological analysis of the obtaimed embryos. A protocol for plantlet regeneration was developed for Gedong Gincu mango clone 289 through secondary somatic embryogenesis. Primary somatic embryos (proembryo and cotyledonary embryos) were cultured in induction medium to induce the secondary somatic embryos. The best proliferation rate was 0.22 in medium with 1 g L-1 Poly Vinyl Pyrrolidone (PVP) for multiplication of secondary somatic embryos. Maturation of inoculum derived from the proliferation medium supplemented with 2 g L-1 of activated charcoal on medium containing 0.4 mg L-1 BAP provides the average 2.39 embryo formation of cotyledonari phase. The highest germination frequency (20%) was obtained in media with GA3 1.5 mg L-1.Keywords: endosperm, Gedong Gincu, Mangifera indica L, secondary endospermic embrio
