Abstract

Patchouli oil is found in all vegetative part of Pogostemon cablin. Therefore, a high biomass is important to increase production of patchouli oil. Biomass production is on of plant growth indicator. Plant growth is a effected by genetic and environmental factor. Light intensity will effect to chlorophyl syntesis, photosynthetic rate, transpiration and hormonal balance. The aim of this research is to study effect of light intensity on biomass production of Pogostemon cablin. Design of research is CRD (Complete Randomized Design), with one factor which is light intensity. There were difference of light intensity that use astreatments. These are : 96 LUX, 340 LUX and 780 LUX. Each treatment was replicated five times. Result indicated that, light intensity affect biomass production of Pogostemon cablin. At light intensity of 96 LUX, biomass productions is the most optimum. An increase of light intensity, biomass production ofPogostemon cablin is reduction.

Abstract

The aim of this research is to know the allelochemicals effect of  rice var. IR 64 residues extract on germination and growth soybean var. Grobogan seedling. This experiment  uses completely randomized factorial design (3x5). The fist factors is extract resources (root, straw, and hull) and secont factor is level concentration extrac (0%, 25%, 50%, 75%, dan 100%) with 5 replicates. Data analysed using ANOVA and DMRT.The results showed that allelochemicals from residue of rice IR 64 extract inhibit the germination and growth soybean var. Grobogan seedling, the higher concentration of the treatment the greater inhibition. Inhibition most likely caused by a hull rice extract.   Keywords: Glycine max, Oryza sativa, allelochemical, phenol

Abstract

The research was conducted to determine the morphology , physiology and anatomy adaptation from eceng gondok in waste water pollution. The research was done at the laboratory of Botany Structure and function. The design of the experiment use was split plot design based of Completely Randomized Design. First factor was density 2 and 4, second factor was 3 waste was LIK, drugs and metal foundry with water to control. The treatment was 3 replicates, The experiment was long 20 days with leaf morphology parameter ,growth/ physiology parameter ( long root, content of chlorophyl leaf) and anatomy parameter ( leaf,and stalk leaf and root). The result of the research indicated was leaf morphology adaptation on drugs waste and physiology adaptation on third waste and root anatomy adaptation was drugs waste with protrution branch root.

Abstract

Aquatic plants have important role in water ecosystem. They serve as the main producer, oxygen suplier and heavy metal absorbtion. Beside that, aquatic plants also economically potencial, such as sources of chlorophyll, carotenoid and vitamin C. The aim of this experiment is to analize the content of total chlorophyll, carotenoids and vitamin C in 13 species of aquatic plants. It is expected that these plants maybe used for commercial purposes. The plants were collected from Rawa Pening, Genuk stream, and brackish water shrim pond in Kendal and Jepara. These chemical analysis were done by spectrophotometer, whereas vitamin C content was measured using iodometric titration method. Results indicated that the highest content of chlorophyl was resulted by Ipomoea aquatica, which is 22,1 mg/L. The highest content of carotenodid and vitamin C is resulted by Nymphaea sp., which were 3,42 mg/L and 14,1 mg/30 g respectively. It is concluded that Ipomoea aquatica and Nymphaea sp. have good commercial value as sources of pigment and vitamin C.

Abstract

Senyawa alkaloid dari tanaman Solanaceae memiliki potensi obat antara lain sebagai antibakteri bahkan memberi efek halusinasi. Alkaloid pada kecubung, Datura metel disintesis pada organ akar dan diakumulasi pada bagian pucuk. Salah satu metoda untuk produksi senyawa alkaloid tersebut adalah dengan menginduksi perakaran dari kalus yang berasal dari daun (induksi kalus berakar). Produksi alkaloid dapat ditingkatkan dengan memodifikasi komponen mikronutrien dari medium dasar MS (Murashige&Skoog).  Penelitan ini bertujuan untuk mempelajari pengaruh peningkatan konsentrasi mikronutrien terhadap pertumbuhan dan kandungan alkaloid total dari kalus berakar.  Kultur diperoleh dari induksi kalus dalam medium MS tanpa zat tumbuh dengan perlakuan konsentrasi mikronutrien.  Pertumbuhan kultur ditentukan dari berat segar dan berat kering,   sedangkan kandungan alkaloid total dianalisis dengan metoda titrasi. Data dianalisis secara deskriptif. Hasil penelitian menunjukkan  bahwa peningkatan konsentrasi mikronutrien hingga 2,5 kali dari medium MS menghambat pertumbuhan kalus berakar. Namun demikian, kondisi ini tampak tidak mampu memacu produksi senyawa alkaloid dari kultur.
