Abstract

The study aims to investigate the optimal dosage of foliar fertilizer to the growth and productivity of  some fruit vegetables exposed to manipulated grasshopper sound  on the frequency of 4500 Hz. “Intan” variety tomato,“Kresna” variety chili and “parade tavi” variety snake bean was treated in 6 dosages of foliar fertilizer, This research is an experimental research using randomized blok design conducted from December,2012 to October, 2013 at Rowobayem, Kabupaten Purworejo, at Ngalas, Kabupaten Klaten, and at Kricaan, Mesir,  Salam Kabupaten Magelang. Parameters measured were the area of stomatal opening, leaf area, plant fresh weight, plant dry weight and the yield. Research results show that there is  a significant effect of dosage variation of foliar fertilizer on tomato plants  on the plant fresh weight, plant dry weight, and tomato weight; on chili plants  on leaf fresh and dry weight, dry weight of leaf and chili weight. Meanwhile,  the optimal dosage of foliar fertilizer for tomato plants is 1.75 cc/l, for chili plants is 1.25 g/l and that for snake bean plants is 1.25 g/l. Key words: sound wave, chili, tomato, snake bean, growth

Abstract

In order to suit and respond to the develop-=ment of science and technology and other relatedissues, a curriculum replacement is a necessity.This curriculum analysis was carried out inorder to observe the development of genetics subjectmatter in the curriculum of 1984 into that of1994 and the relevance of these curricula to the anticipationof recent and future developments. Geneticswas studied equally well. Analysis was conductedby comparing the curriculum of 1984 to that of 1994and considering the development of recent and futuregenetics.The result shows that the genetics subject matterof the curriculum of 1984 has not shown any change;however, biotechnology as applied genetics is added tothe curriculum of 1994. In conclusion, the genetics subjectmatter of the curriculum of 1984 is still not adequateto anticipate the development of recent and hturegenetics. Addition of some related subject mattershould be proposed, covering genes and gene expression,chromosomes (structure, variation of structure,variation of chromosome numbers) and cytoplasm inheritance.
