Abstract

Alternative is needed to overcome the problem of dandruff caused by C. parapsilosis. Endophytic fungi isolated from plants are capable of synthesizing compounds to produce various secondary metabolites. This study aimed to obtain the most active endophytic fungal isolates, determine the class of compounds, and determine the antifungal activity of the endophytic fungi (M. calabura) against C. parapsilosis.  Fifteen isolates of endophytic fungi isolated from M. calabura were coded FDK1-FDK15. There was a color change in the media after 30 days of cultivation isolates of fungi. FDK4 and FDK13 have potential as antifungals. FDK13 fungal extract had the highest inhibition zone diameter of 20.00 mm. 20 eluates were obtained from the isolation of com-pounds (Thin Layer Chromatography), FDK 131, 1314, 1317, and 1320 eluates are compounds of the terpenoid group and FDK1316 eluates are phenol group compounds that are active in inhibiting yeast growth. FDK1317 was the most active compound isolate in inhibiting the growth of C. parapsilosis with an inhibition zone diameter of 12.5 mm.

Abstract

Herbal medicine is becoming a trend in curing several diseases especially degenerative because of the bad effects of synthetic drugs. Tembesu plant (Fagraea fragrans Roxb.) is traditionally used for degenerative diseases. This study aims to separate bioactive compounds (active fraction), pure isolate compounds from tembesu leaf, then observe antioxidant activity. The methods used are maceration extraction, liquid-liquid fractionation, purification of compounds by gravity chromatography column and antioxidant activity by scavenging DPPH radicals. The results showed that the active antioxidant fractions were n-hexane and ethyl acetate fractions. The results of purification of antioxidant compounds, obtained 6 isolates N1, N2, N4, N5, E8 and E11. Antioxidant activity (IC50) of pure isolates N1 (13.72 ppm), N2 (28.93 ppm), N4 (110.44 ppm), N5 (177.23 ppm), E8 (82.50 ppm) and E11 (12 ,86 ppm). The antioxidant compounds that have been isolated are terpenes (N1, N2, N4, E8), phenols (N5) and flavonoids (E11). This study concluded that tembesu leaf have antioxidant potential. Antioxidant bioactive compounds in tembesu leaf have the potential to be developed into standardized herbs and phytopharmaceuticals.

Abstract

The landfill environment in Palembang City produces various types of waste so that people keep free-range chickens around the environment, which is potentially harmful to livestock health. This study aims to determine the color morphology of the internal organs (liver and heart) and the relationship between body weight and organ weight. The number of free-range chickens used was 30, with one year. The morphological description of organ color was carried out by direct observation, and sampling was carried out by weighing free-range chickens body weight and organ weight. This study used the Pearson correlation statistical test, and secondary data was collected on waste data in the landfill environment. The results showed that the relationship between body weight and liver weight was 0.694, and the correlation value between body weight and heart weight was 0.663 in native chickens in the landfill environment. The results of the two values have a strong correlation interpretation, which means that when the chicken's body weight increases, the weight of the liver and heart of the chicken will also increase. The liver is faded red with normal size in native chickens in the landfill environment in the morphological picture. While the color of the heart is red, and the size is normal.

Abstract

Most of the paddy fields in the city of Palembang are rawa lebak land that scattered on the banks of the Musi River. One of the centers of rawa lebak rice in Palembang City is in Gandus District, which has an area of 1,017,255 hectares of rawa lebak rice fields.  The productivity of rawa lebak rice in Gandus District (4.4 tons/ha) is still lower than the average productivity of South Sumatra Province (4.975 tons/ha) and national (5.13 tons/ha). The purpose of this study was (1) to analyze the factors that influence rice production in rawa lebak rice farming in three typologies, namely  shallow, middle, and deep rawa lebak land, and (2 ) to analyze the efficiency of the use of rice production factors in rawa lebak rice farming in three typologies of rawa lebak land. The research was conducted in Gandus District, Palembang City. Sampling used purposive sampling method and taken as many as 93 farmers, consisting of 31 farmers in each rawa lebak typology.  The analysis used is a Cobb-Douglass model regression and t-test to determine the effect of production factors, and efficiency analysis to determine the efficiency of the use of production factors. The results showed that (1) The production factor of urea and NPK fertilizers had a significant affect on farming productivity in all   typologies of rawa lebak land.  Land area, seed, and pesticide factors had no significant effect on farming productivity  in all typologies of rawa lebak land. Meanwhile the labor factor had a significant effect in middle and deep rawa lebak land, but had no significant effect in shallow rawa lebak land.(2) The production factors of land area and seeds are inefficient in all land typologies. The production factor of urea  and NPK fertilizer has not been used efficiently in all land typologies. The use of pesticide factor is inefficient in the middle and deep rawa lebak land, while the use of labor is inefficient in the shallow and deep rawa lebak land.

Abstract

Pentalonia nigronervosa Coquerel (Hemiptera; Aphididae) is the main vector of banana bunchy top disease caused by Banana Bunchy Top Virus (BBTV). The disease is an important and most damaging disease to the crop because infected bananas fail to produce fruits. As the vector of BBTV, P. nigronervosa is able to lives not only on banana plants but also on others plants, especially those belong to Family Zingiberaceae. The objective of this research was to reveal the biology of P. nigronervosa on banana and other plant species belong to Family Zingiberaceae commonly found around banana cultivation areas. The research was conducted in the Laboratory of Entomology, Department of Plant Protection, Faculty of Agriculture, Sriwijaya University from June to December 2021. The research was an experimental research arranged in a Completely Randomized Design using plant species as treatment and was replicated 10 times of replications. Young suckers of banana and zingiberaceous plants were used to rear the banana aphid where all biological aspects of the aphid were observed. P. nigronervosa and the young suckers were placed in a transparent pot covered with transparent plastic with a window made from cheese cloth to facilitate air movement. Room temperature was set to approximately 25oC since the aphid grow and reproduce well under such temperature. The results showed that P. nigronervosa are able to live and reproduce not only on banana but also on seven species of Zingiberaceous plants with little variation of some morphological and biological parameters. The significant different was found between biological characteristics of the aphid lived on torch ginger and cardamom which had longer life cycle but smaller fecundity compared to other experimental hosts used in the research.

Abstract

The black soldier fly (BSF)  Hermetia illucens L.(Diptera:Stratiomyidae) is widely used in biorecycling organic waste has gained huge populatarity in different  industrial. And commercial sector  becouse of its excellent potential to treat organic waste and high biomass production.  The obstacle experienced during the rearing process was that a small number of eggs were obtained, therefore efforts were made to increase the black soldier fly population by providing bait in the form of attractants.  Media bait technique in the form of several media with a specific and pungent aroma, so that it will lure BSF females to mate, lay eggs, extend life time. The present study deal to investigation of different number of mating pairs, eggs weight dan lifetime as function respon of different lure media.This study used a completely randomized design (CRD) with (1) cassava tape, (2) Fermented bran (3) rotten pineapple (4) rotten banana media with each treatment repeated 6 times with the variables observed were the number of mating pairs of fly (per day), egg weight, and life span of imago.  each attractant medium had an effect on the number of mating females, the weight of the eggs laid and the length of life of BSF. The best medium was rotten pineapple media (number of mating pairs 55 pairs of BSF, and egg weight laid 0.007 per day) while the worst medium was fermented bran media with a long life (10.9 days)

Abstract

The pine forest of Kragilan village, Magelang, is a forested area on the west slopes of Mount Merbabu with a humid environmental condition. The conditions make this region suitable for the growth of a macrofungal community. The macrofungal inventory in Merbabu Mountain is very limited and this is inversely proportional to the increasing deforestation. Thus, the macrofungal inventory is a fundamental way of managing natural conservation in this area. The study aimed to provide information and the potency of macrofungi found in the pine forest area of Kragilan, Magelang. The method used is purposive sampling in the research area, and the fungi obtained were identified based on characteristics with some related references. This research described eight species of eight different genera, including one from the Ascomycota (Xylaria sp.), and seven others from the Basidiomycota (Auricularia auriculajudae, Lentinellus sp., Mycena sp., Skeletocutis sp., Gymnopilus sp., Coprinopsis sp., and Coprinellus disseminatus). The current study is the first report on macrofungi diversity in the research area. Further exploration is still needed to record the macrofungal diversity on the western slopes of the Kragilan pine forest.
