Abstract

The research was carried out to study the effect of fertilizer on the growth (plant height, number of leaf, length and width of leaf, fresh weight) and flower production of velvet leaf ? genjer {Limnocharis flava (L.) Buchenau} and to analyze nutrient potential i.e. proximate and amino acids in leaves and flowers (including stalk). Seedlings of velvet leaf with 6 leaves were planted and fertilizer treatments were applied in one week after planting. Planting media were mixture of soil:manure:compost (2:1:1). The fertilizer treatments included control, NPK2, NPK4, MU2, MU4, POH2 and POH4. The plants were cultivated until 5 Weeks After Fertilizing (WAF). The results showed that velvet leaf can be successfully cultivated in plastic pot on planting media added with fertilizer. The highest plant growth and flower production were in the MU4 treatment (NPK Mutiara 27-5-5, 4g/plastic pot). Application of starTmik Biofertilizer 4cc/50cc water/plastic pot showed as good performance as the MU4 treatment, however, the dosage and application frequency need to be increased. The proximate analysis on leaves and flowers showed considerably high percentage of crude fibre (1.56% and 1.42%), protein (2.04% and 1.98%) and carbohydrate (3.16% dan 2.98%). Amino acid analysis revealed 9 numbers essensial amino acids and 8 number non essensial amino acids.

Abstract

An experiment with the aim to identify the cause of disease in Indo-Pacific bottlenose dolphins, Tursiops aduncus was conducted in Pathology Laboratory of Institute for Mariculture Research and Development, Gondol, Bali. The diseased fish showed lost appetite, swim slowly, and haemorrhage on the body surface. These clinical signs indicate that the fish infected by bacteria. The bacteria then were isolated aseptically from different parts of fish body including chin, abdomen, dorsal and caudal fins. Some media were used to isolate the bacteria, namely Triptic Soy Agar (TSA) as a general medium, Thiosulphate Citrate Bile Salt Sucrose Agar (TCBSA) for Vibrio bacteria, Cytophaga Agar (Cyt-A) for Flexibacter bacteria, and KF-Strep Breeders media for Streptococcus bacteria. As a result, one dominant bacterium was isolated from TSA and TCBSA. No bacteria growth showed on Cyt-A and KF-Strep media.The isolate was gram-negative, fermentative, swarm on TSA, growth with yellow colony on TCBSA. Based on its characteristics the isolate identified as Vibrio alginolyticus. Minimum inhibitory concentration (MIC) against Vibrio alginolyticus were 1 ppm for Nifurpirinol, 5 ppm for Penstrep, and 10 ppm or Elbaju.

Abstract

SULASTRI, I. RACHMATIKA & D.I. HARTOTO. 1985. Feeding and reproductive patterns of Torspp. as a base for its aquaculture. Berita Biologi 3(3): 84 -90. A study on the feeding and reproductive characteristics of Tor spp. as a base for aquaculture was done in laboratory and field conditions. Qualitative observation on the feeding habits of Tor douronensis (C.V.) do not show a restriction of the main diet to autochthonous sources. Algae were the main diet, followed by detritus, insects, diatoms, plant material, mosquitoes larvae and desmids. Laboratory observations show that T. douronensis eat first the food that is most concentrated, followed by the food that floats on the surface and last, foods on the bottom. Spearman Rank Correlation reveals that there was food overlaps between groups of fishes of different maturity stages from species collected in the field. It was found that there was a morphological change of male T. soro and a decrease of condition factors that were correlated with the increase of maturity stage. Vision as a significant factor affecting feeding and reproduction of Tor spp. and its relation to aquaculture application was discussed.

Abstract

Isolation of entomopathogenic fungi and their extracellular enzyme activity from rhizosphere soil were carried out. Soil samples were collected from rhizosphere under Arecaceae plant collection and a shrub in Bogor Botanic Garden, West Java; and another samples were gathered from forest floor on peat land in Sebangau National Park, Central Kalimantan. Insect bait method was used to catch fungi from soil samples by using Coptotermes sp. termites and Xystrocera festiva larva in the laboratory. A total of 38 fungal isolates belonging to 18 species and 12 genera were successfully isolated and identified. Isolated fungi were dominated by Deuteromycotina; and Fusarium is the most common (5 species). Peat and Pinanga coronata rhizospheres; and termites bait gave the highest fungal diversity of 9 species respectively. All fungal isolates did not indicate chitinase activity, but 60.53 %, 10.53 % and 13.16 % had both of lipase and protease; lipase and protease activities, respectively. Only 15.79 % fungal isolates were negatively in lipase or protease activities.

Abstract

Spent Mushroom Substrate (SMS) is a composted growing medium that results from the mushroom growing process. The utilization of SMS for biofertilizer or soil conditioner would be an important point in green agriculture. The study revealed the lignocellulolytic activity from 20 isolates of Fungi and 13 isolates of Bacteria which were isolated from sawdust as a spent mushroom substrate of Pleurotus ostreatus. The selected microorganism then would be used as inocullant for the production of biofertilizer using SMS as a main material. The lignocellulolytic system consist of laccase, cellulase and xylanase activity was analyzed. The results shown that among 20 isolates of Fungi, the highest activity of laccase, cellulase, and xylanase was obtained from the isolates 2F1, 2F4 and 2F5. There was (6.153 U, 4.662 U, 3.791U) for laccase, (6.740, 3.711 U, 3.605 U) for cellulase and (6.870 U, 4.673 U, 3.773 U) for xylanase respectively for 2F1, 2F4 and 2F5. Furhtermore, the characterization of the highest lignocellulytic fungi was also conducted. The isolate 2F1 opimally grow in pH 5 at 40oC, isolate 2F4 in pH 9 at 30oC and isolate 2F5 in pH 5 at 30oC. The identification of isolated fungi are in the progress.
