Abstract

The elephant in Way Kambas National Park (TNWK) is living side by side with the buffalos at the grazing area of TNWK’s buffer village. Considering that, the elephant may compete for food when the buffalo enters the conservation area. Data on the diversity of forage plant species is needed in managing buffalos livestock. This study aimed to identify the forage plants from undigested plant fragments in buffalo feces samples from TNWK’s buffer village. Samples were taken from 10 individuals of buffalo in savanna and palm oil plantation. Analysis of the plant composition was carried out by making microscopic whole mount paradermal sections of undigested plant fragments in the feces. Identification refers to epidermal characteristics that are matched with databases and references. The results showed that there were 21 types of epidermal cells which were dominated from Poaceae characterized by Gramineous stomata. The plants fragments found in almost all of the fecal samples were Hymenachne (Poaceae) and Fimbristylis (Cyperaceae). About 9 of the 21 species of plants consumed by buffalo in the buffer village are also foraged by elephants.

Abstract

Antibiotic resistance is a global challenge, especially in the treatment of bacterial infections. This study aims to explore the antibacterial and antioxidant potential of bioactive compounds isolated from soil bacteria in Samarinda, East Kalimantan. Of the 30 isolates tested, 1 potential isolate was obtained, namely isolate code T1.16. This potential bacterial isolate was further cultured and fermented in Tryptic Soybean and Luria Bertani Broth medium to obtain its crude secondary metabolite. Interestingly, its crude extract showed antibacterial activity with MIC values of 100.4-3,211 µg/ml against Escherichia coli strain ATCC 8739, Pseudomonas aeruginosa strain ATCC 9027, Bacillus subtilis strain ATCC 6633, and Staphylococcus aureus strain ATCC 25923. Based on 1,1-diphenyl-2-picrylhydrazyl (DPPH) method was used to identify antioxidant activity, IC50 values obtained ranged from 990-1730 µg/ml. Ultimately, by using Gas Chromatography Mass Spectrometry (GC-MS) analysis, bioactive compounds in the form of Cyclo(L-prolyl-L-valine), 2-methylpropyl and phenylmethyl in bacterial extract T1.16 have potential antioxidant and antibacterial bioactivities. These results support the potential development of new antibacterial and antioxidant compounds from soil bacteria, as well as the importance of further exploration for pharmacological applications.

Abstract

Bees are one of the pollinators that a honey producing agent as well. Honey derives from nectar that stored and procees in honey stomach. The quality of honey is determined by physical, chemical and microbes in the honey stomach as well. This study was aimed to analyze the diversity of bacterial communities (bacterial metagenome) derived from bee’s honey stomach of A. mellifera, A. cerana, and T. laeviceps using Denaturing Gradient Gel Electrophoresis (DGGE) method. Previous researches of bacterial communities are more focused on the entire digestive tract, which is not specifically in honey stomach of the bees. The diversity of bacterial communities showed differences among three bee’s species. The number one of A. cerana has the highest number of Operational Taxonomic Units (OTUs), i.e., 15 OTUs compared to the other sample. While the T. laeviceps number two show the highest percentage of OTU dominant at 59.4%. The bacterial community in bees honey stomach of A. mellifera, A. cerana, T. laeviceps the similarity of bacteria from phylum Firmicutes, Proteobacteria, Acidobacteria and Fusobacteria. Actinobacteria and Bacteroidetes phyla are found only in A. cerana honey stomach.

Abstract

Betta fish are freshwater species known for their territorial behavior and pronounced aggressiveness. The beauty of the color, shape and pattern of fish is special attraction so that it has high selling value, especially in males. Reversal sex through masculinization techniques, is able to produce higher study ratio. This study aims to test effectiveness of immersion betta fish (B. splendens) larval stage in honey solution and study its effect on fish survival. This study used complete randomized design (RAL) method with one factor in the form of immersion time. There were five lengths of immersion as treatment, 0 hours (Control), 24 hours (P1), 28 hours (P2), 32 hours (P3) and 36 hours (P4) with 3 tests each. Larvae used are aged 3 days after hatching. The results showed that length of soaking had a significant (P<0.05) on survival rates in all treatments. The percentage of male sex observed in the K treatment was 21.66±4.81%, P1 was 50.85±2.92%, P2 was 50.58±4.59%, P3 was 52.46±3.90% and P4 was 0%. The effective soaking time treatment is for 24 hours. The effect of natural honey on the masculinization of betta fish was effective in P1 treatment of 50.85±2.92% and survival rate of 94.95±1.37%.

Abstract

Caladium, a member of the Araceae family, is known for its diverse leaf colors and patterns, referred to as variegation. This study aimed to examine the relationship between pigmentation patterns, variegated areas, and leaf anatomy, chlorophyll content, and photosynthetic rate under different light conditions. Two light treatments were applied, full sun (0% shade, 37,500 lux) and 70% shade (12,000 lux), using direct morning sunlight. Seven distinct types of Caladium were used in the experiment. Photosynthetic rate was measured using a LI-6400 portable photosynthesis system at Photosynthetic Photon Flux Densities (PPFD) of 100, 400, and 800 µmol m-2 s-1. Pigment analysis included quantification of chlorophyll, carotenoids, and anthocyanins, while morphological assessments focused on leaf size, variegated area, and leaf thickness. Plants exposed to higher light intensity developed smaller, thicker leaves with mostly larger proportion of variegated area. Chlorophyll, carotenoid, and anthocyanin contents varied depending on plant type and light treatment. The net photosynthetic rate (Pn) increased with higher PPFD and was greater in unshaded conditions. Among the plant types, V3 and V4 exhibited characteristics typical of shade-adapted species, while V6 showed traits of sun-loving plants. Overall, the study demonstrated that variegated Caladium plants maintain comparable net photosynthetic rates despite differences in pigmentation patterns and variegation intensity.

Abstract

Sambiloto, often referred to as the “Raja Pahit”, is a plant belonging to the Acanthaceae family. This plant is known to produce secondary metabolite compounds with various biological benefits, including antioxidant properties. Antioxidant compounds have been shown to counteract the formation of free radicals that are harmful to the body. The antioxidant activity of the Sambiloto plant can be evaluated using endophytic fungi associated with it. This study aimed to identify secondary metabolite compounds and evaluate the antioxidant activity of AS-3 Fungus isolated from the Sambiloto roots. Phytochemical analysis revealed that the ethyl acetate extract of AS-3 contained terpenoids, flavonoids, and alkaloids. In addition, the antioxidant activity test showed promising results, with an IC50 value of 10.225 ppm, indicating high antioxidant potential. This is the first report on the phytochemical screening and antioxidant activity test of the ethyl acetate extract of AS-3 fungus isolated from Sambiloto roots.
