Abstract

A study on the effect of Marasmius  pulcheripes J8 and soil fungi interaction on the activity and ability of laccase to degrade palm oil mill effluent (POME) was previously conducted, and some Basidiomycetes fungi were identified capable. Therefore, the aim of this study was to determine the ability of Marasmius pulcheripes J8 to degrade POME in the presence of inducers, and interactions with soil fungi. Furthermore, 3 types of inducers were applied to elevate its laccase activity, which include CuSO4, sucrose and Ammonium tartrate. In addition, M. pulcheripes J8 was grown together with soil fungi, encompassing Aspergilus niger NK and Penicillium sp R 75, in order to boost the action. The results showed the highest laccase activity was in M. pulcheripes J8 pure culture on a PDB medium of 3566.04 U / mL.  Moreover, the POME decolorization was up to 74.25% after 20 days of incubation, and reduced COD level was 81%. Meanwhile, the addition of an inducer has never been performed before, and the outcome of this investigation showed the ability of M. pulcheripes J8 to degrade POME, and decrease environmental pollution. POME waste treatment using fungi is more affordable than other methods.

Abstract

The study was conducted to develop local fruit plants and to improve vegetable production at the Plant Germplasm Garden of RC for Biotechnology-LIPI. Carambola (Averrhoa carambola), durian (Durio zibethinus) and guava (Psidium guajava) were propagated vegetatively (grafting and budding) and were grown on the media containing grass compost (K-1), spent compost of paddy straw mushroom (K-2) or oyster mushroom (K-3) in combination with rootstock length of 45-55 cm (TB-1), 65-75 cm (TB-2) and 75-90 cm (TB-3). Tomato (Lycopersicum esculentum) and kangkung (Ipomoea reptans) were grown on the same media in the screen house. The highest survival rate of grafted durian (71.56%) was obtained from TB-3 grown on K-1 by budding technique. Meanwhile, the highest survival rate of carambola (68.89%) was obtained from TB-1 by grafting technique. The budding technique was not appropriate for guava (0 % of survival). Application of K-3 of 3 kgs on tomato plants resulted in the highest fresh weight, length, and diameter of the fruit, and the highest of plant height, total leaves, and biomass of kangkung. The study is expected to be applied to improve fruit plant growth and survival rate as well as a high production of organic vegetable.How to CitePriadi, D., & Mulyaningsih, E. S. (2016).

Abstract

Osteochilus vittatus is a freshwater fish that needs to be developed because it tastes savory and can be used as a biocleaning agent. Research on the effect of supplementation of Spirulina platensis in nilem fish that is maintained in a biofloc system on digestive enzyme activity has never been done before. The objectives of this study were to determine the effect of S. platensis supplementation on Osteochilus vittatus digestive enzyme activity maintained in the biofloc system and to obtain the most optimum level of S. platensis supplementation in improving the  digestive enzymes activity. The study was conducted experimentally with Completely Randomized Design with four treatments and five replications. Osteochilus vittatus were fed with Spirulina platensis level of 0, 2, 4, and 6 g kg-1 for 56 days. Enzyme activity was measured on days 0 and 56 with three kinds of buffer solutions. Amylase and protease activity was analyzed using ANOVA with a confidence level of 95%. The results showed that the highest amylase activity in the liver was 4.764 ± 1.705 U mg-1 protein and proximal intestine was 2.328 ± 0.838 U mg-1 protein. The highest protease activity was found in the liver and proximal intestine with activity of 6.536 ± 0.911 U mg-1 protein and 6.207 ± 2.195 U mg-1protein. Spirulina platensis supplementation level of 6 g kg-1 feed is the most optimum level (p<0.05). Cultivation of fish with S. platensis supplementation in feed can increase enzyme activity and the fish maintenance in biofloc systems can improve water quality.

Abstract

Tuntun angin is one of important floodplain plants in and around Kajuik Lake located in Riau Province, Indonesia. Morphological identification shows that the scientific name of this plant is Elaeocarpus floribundus. The study aimed to confirm the taxonomic status of tuntun angin using matK and nuclear intergenic spacer (ITS) sequences. The methods included fresh leaf DNA isolation, polymerase chain reaction, electrophoresis, sequencing, and data analysis using BLASTn program and MEGA software version 6.06 programs. The results showed that the matK sequence (519 bp) of tuntun angin had highest similarity to E. floribundus matK sequence that was available in GenBank. It was supported by the high max score (937), low E-value (0.0), high identity value (100%), and high query cover (100%). However, the ITS sequence of tuntun angin did not show similarity to E. floribundus ITS sequence because there was no database of the sequence in GenBank. This study was able to confirm the taxonomic status of tuntun angin as E. floribundus using matK sequence and also showed that morphological and molecular identification techniques were complementary to each other. Moreover, this study enriched the DNA sequence database of E. floribundus in GenBank which will be useful for this species molecular identification.How to CiteRoslim, D.

Abstract

The high rate of urbanization in Semarang have caused the land conversion from forest into various human need spaces. The land conversion is not only affect the life of humans but also the animals, including ants. The objectives of this study were to examine the dominance of tramp ants in the settlement area of Semarang City. The method used was the bait trap method using chicken intestine as a bait. Samples of ants were collected from four habitats, i.e., waste disposal area, traditional markets, house area, and urban parks. This study found four dominant ants, i.e., Anoplolepis gracilipes, Paratrechina longicornis, Solenopsis geminata and Monomorium pharaonis. Two of them were categorized as tramp ants (Anoplolepis gracillipes and  Paratrechina longicornis). The highest diversity of ants was found in house  (H'= 2.72).  The waste area tends to be an ideal habitat for particular species, which was proved by the low value of Simpson's dominance index (iD = 0.06) and a high value of evenness index (E=0 0.89). This study provides new information about tramp ants population as pest in urban area. The findings would be beneficial for controlling the population of tramp ants, which are disturbing humans in the settlement area.

Abstract

The Extract of Aloe Vera Peel (EAVP) contains bioactive compounds (flavonoids, alkaloids, tannins, saponins, and phenolics) that it thought to improve pancreas histopatology on rat with diabetes mellitus, therefore it has potential for diabetes mellitus treatment. This research aimed to figure out the effect of EAVP on improving the histopathology of rat pancreas induced by alloxan. This research was an experimental study using a completely randomized design with a randomized post-test design. A total of 25 rats were divided into 5 groups: C(-) was a normal group, fed and drinking standard; C(+) was positive control group, induced by alloxan 120 mg/kgBW; PI, PII and PIII were groups that were induced by alloxan 120 mg/kgBW and were given a full-dose of EAVP of 87.5, 175 and 350 mg/kgBW respectively. The data was assessed using the Kruskal-Wallis and Mann-Whitney statistical analysis. The results of the statistical test showed that the histopathology of rat pancreas of the C(+) group were significantly different compared with the treatment group. Meanwhile, the representation of histopathology of pancreas between PIII and C(-) were not significantly different. It can be concluded that treating hyperglycemia rats with the EAVP for 28 days can improve the representation of histopathology of rat pancreas. At the laboratory level, EAVP has been shown to repair rat pancreatic damage. With this result, Aloe vera has the potential to be developed as a phytopharmaca for the prevention or treatment of diabetes mellitus.

Abstract

Kersen fruit and Lakum leaf contain substances that are potential as an antihyperlipidemic. The aim of this research was to analyze the effects of Kersen juice (Mutingia calabura L.) with dosage 0.2 ml/200 g BW and  lakum leaf extract (Cayratia trifolia L.) with dosage of 40 mg/200 g BW on lipid profile of white rats (Rattus norvegicus L.) with hyperlipidemia. This study used a Complete Randomized Design (CRD). This study used twenty adult male Wistar rats which were divided into five groups : P0 as a control group, P1 as a High Feed Diet (HFD) control group, P2 as a HFD group treated with Kersen juice with dosage of 0.2 ml/200 g BW, P3 as a HFD group treated with Lakum leaf extract with dosage of 40 mg/200 g BW and P4 as a HFD group treated with simvastatin. The treatments were given orally for 28 days. The parameters of this study were the level of cholesterol, HDL, LDL and triglyceride, as well as body weight, and food consumption. One-way ANOVA test was performed to determine the significant differences p<0.05 between groups followed by Duncan test with a 95% significant level. The results showed that compared to Kersen juice with dosage of 0.2 ml/200 g BW, administration of Lakum leaf extract with dosage of 40 mg/200 g BW was more effective in lowering cholesterol level, triglyceride and increasing HDL level, however, they were not effective in lowering LDL in rats with hyperlipidemia. This result shows that kersen and lakum leaf could be an alternative to prevent and avoid further effects of high cholesterol in people with hyperlipidemia.
