Abstract

Studies on the soil nutrient status of a degraded forest under traditional gold mining have been conducted in a forest area in Bojong Pari,Sukabumi,West Java by analyzing nutrient content of soil taken from degraded forest and also from the adjacent virgin forest as a control. Meanwhile, litter deposits from forest floor were collected to be compared. The result showed that the soil is belongs to clay type with the acidity ranged between (based on H2O 1:2,5) 4,72-4,83.Soil macro nutrient content from degraded forest showed N 0,041%; P 0,059 mg/100 g and K 0,222 ppm, this value are lower than that from virgin forest. The litter deposits ( dry weight) taken from degraded forest are 110,53 g/m lower than the virgin forest (230,42 gAn ).It means that traditional gold mining has changed the nutrient status of the Bojong Pan Forest area.

Abstract

One problem in mariculture is mortality caused by diseases. An experiment to evaluate the effectiveness of polyvalent bacterial vaccine combined with anti GSDIV vaccine was conducted in the Institute for Mariculture Research and Development, Gondol, Bali. Polyvalent bacterial vaccine was combined of three inactivated pathogens, i.e. Vibrio harveyi, V. alginolyticus, and Photobacterium leioghnathi. Polyvalent bacterial vaccine administered through bathing method whereas GSDIV vaccine given through intra-peritoneal injection on tiger grouper. The fish was reared for three months in concrete tanks equipped with filter and aeration systems. The fish were fed with dry pellet twice a day. The results showed that titer antibody and survival rate of vaccinated fish were higher than unvaccinated one. The highest titer antibody was obtained on fish vaccinated with GSDIV vaccine (128) followed by fish vaccinated with polyvalent bacterial vaccine (32-64) and combination of polyvalent bacterial vaccine with GSDIV vaccine (32-64), respectively. Relative Percentage Survival (RPS) of vaccinated fish following challenge with live bacteria and virus were ranged from 65-84%. It is suggested that vaccines effective to enhance immune protection of tiger grouper fish against bacterial and viral infections.

Abstract

Walaupun diketahui bahwa makanan serangga menentukan berbagai bentuk mulut dan saluran pencemaannya, hubungan keanekaragaman jenis makanan dan keanekaragaman fungsi dan bentuk mulut seita saluran makanan belum banyak diketahui.Padahal pengetahuan ini mempunyai segi terapan yang beiguna, misalnya dalam membantu menentukan peranan serangga di suatu lingkungan. Kekhasan modifikasi bagian-bagian mulut diharapkan dapat dipakai untuk mencirikan kelompok pemiliknya. Dalam tahap permulaan penelitian morfologi mulut dan saluran pencernaan dilakukan terhadap serangga bermulut pengunyah dan penusuk-pengisap tumbuhan .serta mangsa. Hasil yang diperoleh dimaksudkan untuk menambah data mengenai bagian-bagian mulut dan saluran pencernaan (Snodgrass l935;Metcalf etal. 1962; Nasution 1972) danmenambah data yang dapat digunakan untuk membedakan serangga pemakan tumbuhan dari pemangsa.

Abstract

Mass production by using micro propagation technique has an important role for Lilium longiflorum regarding that it can produce seedlings in relatively short time, disease free, and regularly time. Several factors affected the successful micro shoots and bulblets formation, i.e.medium, explant, and temperature. This research aimed to know the effect of direction and width of scale section on the multiplication of kerk lily in vitro.Research has been conducted in the Tissue Culture Laboratory of Indonesian Coffee and Cocoa Research Institute, Jember.The research was arranged in factorial completely randomised design, i.e.direction of scale section and width of scale section. Two levels of direction of scale section namely longitudinal and transversal and five levels of width of scale section namely 1, 4, 6, 8, and 10 mm.The results showed that scales are able to produce micro shoot only, bulblet only, or both micro shoot and bulblet.The number of micro shoots produced from longitudinal section are higher than those of produced from transversal section. Width of scale section affected micro shoots and bulblets production, which their correlations are quadratic.The trend of micro shoots production was contrary with bulblet production.

Abstract

Parasitic copepods are of the most important parasites in the marine environment. They occupy a wide range of hosts ranging from many major groups of invertebrates to the top predators in the sea. Indonesia with vast ocean area has great opportunity to harbour a large numbers of parasitic copepods. However, only few studies of parasitic copepods have been conducted in this region, and most of them are preliminary studies, particularly on mariculture associated copepods. To date, only 70 species of parasitic copepods have been recorded from Indonesian waters. There is a lack of taxonomical approach on these studies, in which some of the specimens were not identified to species level.This highlights the need for taxonomic study and even molecular study of marine parasitic copepods in Indonesia. This paper aims to review the evolution of research on parasitic copepods in Indonesia and to identify areas in need of future research.

Abstract

Hoya purpureofusca Hook.f. (Apocynaceae: Asclepiadoideae) has been used as an ornamental plant and the international trade of this species has become increasing. This species has restricted distribution on the high elevation of Java and Bali mountains. This epiphyte climber has succulent leaves and umbellate delicate flowers. Flower has star shape, succulent and waxy, purple., c.1 cm in diameter. The observation on the morphological characteristic is aimed to select the best sample for ornamental plant. The total of 17 observed samples were obtained from three populations at Gunung Gede Pangrango National Park, West Java, Indonesia. The selection was based on the node length, size of the leaves, and flower number, size and color. The result showed that P01 from Cibodas could be developed as leaf ornamental plant, because its shortest node and small leaves. SP1 from Selabintana could be developed as flower ornamental plant, it has numerous, larger and deep purple flower. SP1 and P01 have the farest relatives distance among all observed accessions, but still have a similarity of 75%.

Abstract

Research on vegetation, where Hoya purpureofusca Hook.f. grows, has done in the Selabintana Resort, Mount Gede-Pangrango National Park in September 2011. Purposive random sampling was set up for a total of 18 square plots of 10m x 10m, where placed on two different sites. Nine plots were placed in the growing sites of H. purpureofusca, otherwise were placed in other sites. Observation was made in each sampling plots on the number of species at three stages, i.e. seedling, sapling and tree in each sampling plots. The diversity indices (including species richness, heterogeneity, and evenness) were analyzed using Jakcknife index, Margalef index, Menhinick index, Simpson index and Shannon-Wiener index. Species dominance was analyzed by important value index and similarity index whereas species associations was analyzed by chi-square. Based on the analyses, there were differences on vegetation composition and diversity between growing site of H. purpureofusca and non growing site. Schima wallichii (DC.) Korth. is the dominant species that has an important role for the growth of H. purpureofusca.

Abstract

Rutaceae is one of the essential oil resources that is very potential for medicinal, perfumery and other use This study was conducted to analyze the essential oil components resulted from water distillation of kalamanjarik leaves (Micromelum minutum), jeruk \epara leaves ILimnocitrus litoralis) and the leaves and the stem bark of malapotung (Evodia qlabra). The results showed the leaves of kalamanjarik contained approximately 0,70%, jeruk jepara 0,21%, malapotung leaves 0,17% and the stem bark contained 0,50 % essential oils. GCMS analyses of the essential oils gave 3 major components of kalamanjarik leaves i.e /J-pinene (24,41%j, bergamiol (23,01%) and nerolidol (18,90%) and 2 major components of jeruk jepara leaves i.e fl-mircene (70.55) and /t-pinene (24,06 %). Essential oil of malapotung leaves consisted of 39,8J% ct-pinene, 14,26 % 1aR(1aa,4a/3,7a,7aa,7ba)decahydro -1,1,7-lrimethyl-4-methylene-1H-cycloprope azulene and 16,62% S-cadinene as major components, while the stem bark had only one major component, u-pinene (68,37 %) The minor components of the four essential oils will be discussed.
