Abstract

Hairy fig is a tropical medium-sized tree that produces abundant fruits throughout the year. In some Asian countries, the fruits are consumed as traditional medicine and food ingredient. Meanwhile in Indonesia there has not been much use. A series of oral toxicity tests must be conducted to study the possibility of toxic effects and the safety before further exploration. Oral single dose toxicity study of young and ripe hairy fig fruit filtrate has been carried out. Results demonstrated no observed adverse effect level (NOAEL) at a concentration of 100%. This study was aimed to continue the oral toxicity test with repeated dose following standard toxicity procedure by OECD Test Guideline No. 407 with some modifications. Parameters observed were mortality, sublethal effects consisted of physical conditions and behavior, body weight, core temperature, complete blood count, as well as liver, heart, and renal functions by measuring ALT, AST, and creatinine, respectively. Sampling points on day 0, 7, 14, 21, and 28. Results showed no observed adverse effect level (NOAEL) in both young and ripe fruits filtrate at a concentration of 100% however with a tendency to cause anemia and associate with renal dysfunction. Therefore, it is necessary to perform similar method of toxicity test but with lower concentration, also continue with further toxicity tests (subchronic and chronic periods).

Abstract

The food stuffs can be clasified as functional food since the foods can improve the human health. One of them are the food stuffs which have function as antioxidant and antibacterial. These activities were studied on crude polysaccharides from Auricularia auricula. The sample was subsequently isolated using hot water and 1 M NaOH to obtain water and alkali soluble of crude polysaccharides. The antioxidant activity was evaluated using β-caroten-linoleat assay. The results showed that the alkali soluble of crude polysaccharides had the highest antioxidant activity (85.82%) at 350 μg/ml. The water and alkali soluble of crude polysaccharides from A.auricula were evaluated for their antibacterial activity using disc diffusion method. The alkali soluble of crude polysaccharides was found to have the highest antibacterial activity at 100 mg/ml against Staphylococcus aureus InaCC B4 and Escherichia coli InaCC B5 with clear zone values of 3.18 mm and 5.10 mm, respectively. The findings indicated that the alkali soluble of crude polysaccharides from A. auricula could potentially be used in part of well-balanced diets and could be considered as a potential source of natural antioxidant and antibacterial products.

Abstract

The use of biocontrol agent in aquaculture is being adapted as an effective alternative to antibiotics which can lead to the elaboration of antibiotic-resistant bacteria and confer unpleasant impacts to aquatic organisms. Aquatic bacteria have been discovered as biocontrol agents and potential probiotic candidates to improve the health of aquatic organisms, feed efficiency, and disease resistance to aquaculture pathogens. However, local isolate has not intensively been explored and used to increase aquaculture sector productivity. Therefore, this research aimed to determine minimum inhibitory concentrations of their antibacterial compounds against aquaculture pathogens and to characterize aquatic bacteria by their viability in the feed. Four isolates from several aquatic environments in Indonesia (Pseudomonas sp. S1.1, Pseudomonas sp. S1.2, Pseudomonas sp. SL1.1, and Bacillus subtilis KM16) were used to characterize of antibacterial compound and to determine the viability in feed. Ethyl acetate extracts from all isolates showed better antibacaterial activity against Aeromonas hydrophila and Vibrio vulnificus than chloroform and dichloromethane extracts, in which ethyl acetate extract from Bacillus subtilis KM16 showed the strongest antibacterial activity. Pseudomonas spp. were more effective against V. vulnificus (40 mg/mL) and Bacillus subtilis KM16 was more effective against A. hydrophila (20 mg/mL), as proved by the minimum inhibitory concentrations of their ethyl acetate extracts. In this research, Bacillus subtilis KM16 had stable viability in feed than Pseudomonas sp. isolates.

Abstract

The African catfish (Clarias gariepinus) has been introduced several times to Indonesia, including from Thailand (Paiton strain). The breeding of Paiton strain resulted in albino individuals. The present study aimed to investigate the length-weight relationship, condition factor and biometric characteristic of those albinos. Five pairs of each albino and normal coloured Paiton African catfish were artificially bred. Larvae and juveniles from each pair were reared one month of larval rearing phase, one month of nursery phase and two months of grow-out phase, then the total length and body weight were measured for length-weight relationship and condition factor analysis, finally the biometric was characterized. The present study revealed that the relationship between total length (L) and body weight (W) of the Paiton African catfish was positive allometric (W = 0.0038L3.23 in the albino and W = 0.0027L3.27 in the normal coloured one). The albino Paiton African catfish was more rotund (condition factor of 0.79±0.07) than the normal colored one (condition factor of 0.68±0.06). Biometrically, the albino Paiton African catfish has a bigger head portion and fewer dorsal and anal fin rays than those of the normal coloured one. Despite the colour difference, the albino and normal coloured Paiton African catfish were morphologically different.

Abstract

Talangagung landfill, Malang Regency has used the controlled landfill method. The landfill process produces methane gas that has been flowed as fuel so that it is estimated that there are bacteria with a variety of enzymatic activities that have worked in degrading waste. The purpose of this study was to isolate bacteria from landfill and determine the ability to produce amylase, protease, lipase, and cellulase and test the compatibility of bacteria. The methods used include bacterial isolation using the pour plate method and purification of bacterial isolates using the streak plate method. Bacterial selection is done on selective media containing starch, tributyrin, cellulose, and skim milk. There were 21 bacterial isolates successfully isolated 13 consisting of bacterial isolates showed proteolytic activity, 10 cellulolytic bacteria, 8 amylolytic, and 15 lipolytic. The isolates that show compatible results are BTA 5.7.14, BTA 5.7.7, BTA 5.7.12, and BTA 5.7.6 therefore they can be used as a potential consortium for organic waste recycle.

Abstract

The life cycle of Digenea subclass trematodes  that mostly involves snails as intermediate host in the larval stage in the form of sporocysts, redia and cercariae. This study aims to determine the species of freshwater snails, populations and stages of trematoda larvae that infect freshwater snails in the paddy fields and also the factors that influence the population of trematoda larvae. This research method uses purposive random sampling. Snails were collected from paddy fields in Sleman Regency, Yogyakarta City and Bantul Regency, Special Region of Yogyakarta. Snails and Trematodes larvae were identified based on morphological characters with a microscope. The results showed that the species of freshwater snail as  an inang antara  of Trematode was Lymnaea sp. (96.9%), Pomacea canaliculata (2.6%), and Brotia sp. (0.5%). The total population of trematoda larvae in freshwater snails was 4329 individuals with the largest population in Sleman Regency (2784 individuals). Trematode larval stages found were sporocysts (4.8%), redia (8.3%), Leptocercous type cercariae (35.2%), and Furcocercous type cercariae (51.7%). The most trematode larvae found in  fresh water snail was  Furcocercous type cercariae. Factor affecting trematode larvae population are the species and abundance of freshwater snail.
