Abstract

The obstacle to increasing the soybean production is an infection of rust disease caused by the biotrophic fungus, Phakopsora pachyrhizi. The research objectives were to determine the anatomical resistance and the level of resistance of soybean cultivars against rust disease. The embedding method for observed leaf structural anatomy. The disease severity based on the method of International Working Group on the Soybean Rust (IWGSR) rating system.  The experiment was arranged as a Completely Randomized Design (CRD) with Factorial Pattern and five times repetition. The first factor was soybean cultivars, namely Gepak Kuning, Slamet, Tanggamus, and Wilis. The second factor was P. pachyrhizi inoculation with 0 uredospores/mL (uninoculated) and 104 uredospores/mL (inoculated). The results showed that the soybean cultivars that have thicker cuticle and epidermis, high trichomes and low stomatal density, and low of stomatal conductance have better anatomical resistance to leaf rust disease. Wilis and Slamet cultivars are resistant cultivars, indicated by disease intensity of 20% and 24.6%, respectively. While the Tanggamus is moderately resistant cultivar and Gepak Kuning is a susceptible cultivar, indicated by disease intensity of 56.5% and 85.3%, respectively. The novelty of selection soybean germplasm against biotrophic fungal disease are important and effectiveness in order to increase the crop productivity. These three soybean cultivars potentially serve as genetic sources to develop high yielding soybean cultivars and resistant to rust disease.

Abstract

South Bangka Regency has a long history of using medicinal plants as part of its medical system. However, the potential associated with this aspect of traditional medicine remains understudied and poorly explored. This study aimed to describe the types of medicinal plants and analyze the use of medicinal plants to treat early childhood disease by the local community of South Bangka Regency. The research method used was open interview with local people using the questionnaires. The data was analyzed using Use Value (UV), Fidelity Level (FL), and Relative Frequency of Citation (RFC). The analysis identified 55 plant species from 35 families. The most common families were Euphorbiaceae (8.92%), Fabaceae (7.14%), Poaceae (7.14%), Zingiberaceae (5.36%), and Lamiaceae (5.36%). The most widely used plant was shallot plants (Allium cepa L.) with values of UV, FL, and RFC were 0.67, 66.67, and 0.015, respectively. This study revealed the richness of ethnomedicinal knowledge in the South Bangka Regency. Finally, it is expected that this ethnobotany study can provide a database for further scientific research. The community’s knowledge as a legacy will not be repeated if it is not inherited. Besides, this biodiversity is very important as a socio-economic and ecological asset in South Bangka Regency which must be protected by all means from over exploitation.

Abstract

Jojoba (Simmondsia chinensis (Link)) is a shrub plant that widely used as cosmetic ingredients especially jojoba oil. When making jojoba oil, the residue still reminds and become waste. This study aimed to determine the antioxidant activity of jojoba seed residue (JSR). Jojoba seed residue was collected from Sudan. The JSR extracted by maceration with n-hexane, ethyl acetate, and 70% ethanol solvent. The antioxidant activity was determined using DPPH (2,2-diphenyl-1-picrylhydrazyl) assay. The result showed that 70% ethanol extract of JSR had the highest antioxidant activity with 50% Inhibition Concentration (IC50) value of 219.42 mg/L. The 70% ethanol extract was fractionated by using silica gel column chromatography with gradient elution produced 10 fractions. All fractions showed antioxidant activity (IC50106-447 mg/L). Fraction 3 had the highest antioxidant activity with IC50 value of 106.26 mg/L. Therefore, JSR has a great potential for use as a raw material in cosmetic and pharmaceutical products industry, or as a source of bioactive compounds.

Abstract

Flamboyant flower (Delonix regia) extract can increase proliferation and differentiation rates of mesenchymal stem cells (MSCs) into specific cells such as bone, nerve, and fibroblast cells. The extract possess metabolic compounds that may act as antibiotics, anti-inflammatory, antimicrobial, diuretic, anthelmentic, astringent, leucorrhoea, and potentially increase the body's metabolism normally. This study aimed to investigate expression level of alkaline phosphatase (ALP) by mice MSCs treated with flamboyant flower extract in vitro. Here, mice bone marrow cell cultures were treated with flamboyant flower extracts of 0.6 mg/ml (P1), 0.7 mg/ml (P2), 0.8 mg/ml (P3), and 0.9 mg/ml (P4). Untreated cell culture was used as negative control (P0). Expression of ALP gene was measured by RT-qPCR method. The results showed that mice mesenchymal stem cell could differentiate into bone, nerve, and fibroblast cells. The addition of flamboyant flower extract ranged from 0.6-0.9 mg/ml significantly (p<0.05) influenced the expression of ALP by differentiating MSCs. The highest expression was found at the stem cells treated with flamboyant flower extract of 0.8 mg/ml, 0.13 times compared with control. In conclusion, flamboyant flower extracts treatment might increase the expression of ALP in differentiating MSCs.  This information can be used as a basis for finding an appropriate biomarkers for tracking the differentiation and profileration of tissue originated MSCs induced by extracts of medicinal plants.

Abstract

Carotenoids are fat-soluble pigments that have various benefits in health and beauty. The demand and market of carotenoids are increasing; thus, the faster and cheaper biological production of these pigments using microorganisms is desired. In this study, the optimum medium pH and nitrogen concentration for carotenoid production by Rhodosporidium (R.) paludigenum using orange peel extract as substrate were determined. The soluble sugars from orange peels were extracted using distilled water at 100 °C. The yeast inoculum was cultivated in Yeast Peptone Dextrose (YPD) media before fermentation. The independent variables in the fermentation factorial design included initial medium pH (5; 6; and 7) and nitrogen concentration (0; 1; and 1.75 g/L urea in the medium). The decrease in reducing sugar concentration and the increase in biomass dry weight during fermentation demonstrated carbon source consumption by R. paludigenum for growth and carotenoid production. On the sixth day of fermentation (D6), the culture was harvested for the total carotenoid extraction and determination. The highest total carotenoid yield (107.63 µg/g) was achieved by the treatment group with an initial medium pH of 6 without nitrogen supplementation. This result indicated the orange peel extract potential as a substrate for carotenoid production using R. paludigenum as a workhorse. This was the first reported research in natural carotenoid generation using R. paludigenum (strain InaCC Y-236) locally isolated in Indonesia as the producer and orange peel extract as the substrate. Thus, this research would enrich the microbial carotenoid exploration and waste valorization to value-added products at the same time. The study can then be developed further and upscaled for industrial applications.

Abstract

Blue panchax (Aplocheilus panchax Hamilton, 1822) lives in broad ranges of habitat from open waters to closed waters, including at ex-tin mining pits in Bangka Island, Indonesia. Variable habitats might cause morphological variations due to different ecological factors. This study aimed to assess the morphological variation of blue panchax collected from different habitats using truss morphometric characters. Fish samples (70 individuals) were collected from abandoned ex-tin mining pits of different ages and a river in Bangka Island. Twenty-nine truss characters were analyzed using the Kruskal-Wallis test and post hoc with Dunn’s test . The results showed that almost all of the body parts of blue panchax found in ex-tin mining pits and rivers were significantly different (p-value 0.05), except some truss characters of caudal peduncle. The post hoc of Dunn’s test showed a positive correlation between habitats and truss characters (adj. sig 0.05). Some truss characters of killifish were different between ex-tin mining pits with different ages chronosequence, and some other characters were different between pits and river.  This study provides the first data about the morphological variation of blue panchax in ex-tin mining pits of different ages. The data is valuable as a scientific basis of further utilization of ex-tin mining pits in the areas.

Abstract

Hypercholesterolemia is a condition caused by high cholesterol consumption. Tomatoes is well known has cholesterol-lowering effects. However, high consumption of tomato shall be concerned especially prooxidant potential that may damage the organ, especially in liver. This study aims to understand the effect of hypercholesterolemic and tomato administration to the rat’s liver, which is monitored using aspartate transaminase (AST), alanine transaminase (ALT) and histological condition. A total 24 of 12-weeks-old male-rats divided into 4 groups, equally. The K1 as normal group consist of placebo-treatment rats; K2 group as hypercholesterolemia group induced with high-cholesterol diet and 2 ml of cholesterol; K3 group was hypercholesterolemia rats treated with 20 mg of atorvastatin; and the last is K4 group was cholesterol rats supplemented with 16 mg/ day of tomato extract. All samples were treated for 60 days. The highest levels of AST and ALT level was 76.39 U/L and 45.40 U/L, respectively, was found in K2. Then, K4 is not significantly different from K3 and K1 and significantly different from K2. The scoring results showed that all groups experienced damage in the form of parenchymal degeneration, fat degeneration and necrosis. From this study it can be concluded that tomato extract gives a protection to the liver from cholesterol-oxidation damage effect. The updating information about how tomato inhibite liver fattening. The liver condition probably can be considered as biomarker-related hypercholesterolemia and developed a diagnostic marker to prevent increases metabolic disorder in community.
