Abstract

Mango’s mistletoe is one of the herbal plants’ rich in bioactivity. Secondary metabolites are not only produced by plants but also by microorganisms that live in tissues. One of these microorganisms is endophytic mold. The ability of endophytic molds to synthesize secondary metabolites is an opportunity for large-scale production in a short time without causing the exploitation of natural materials. This research aimed to explore and identify endophytic molds from the leaves and stem of the mango mistletoe to obtain the genus of molds. The stages of this research consisted of isolation by direct planting with sterilization, purification, growth rate measurement, characterization, and identification carried out macroscopically and microscopically. DBM 1 and DBM 2 belong to Aspergillus sp., DBM 3 belongs to Cladosporium sp., DBM 4 belongs to Neurospora sp., TDBM 1, TDBM 2, and TDBM 3 belong to Hormiscium sp. The growth rate of Aspergillus sp. relatively fast, with the increase in diameter of Aspergillus sp.1 colony from 2.45 cm to 5.05 cm and that of Aspergillus sp.2 from 2.73 cm to 5.35 cm. In the Cladosporium sp., there was an exponential phase with an increase in diameter from 2.15 cm to 4.65 cm. In Neurospora sp., there was an exponential phase with an increase in diameter from 0.63 cm to 3.65 cm. The growth rate of Hormiscium sp. is quite fast, with an exponential phase with an increase in the diameter of the colonies of Hormiscium sp.1 from 2.63 cm to 7.21 cm, Hormiscium sp.2 from 2.45 cm to 6.94 cm and Hormiscium sp.3 from 2.85 cm to 7.85 cm.

Abstract

Sodium nitrite (NaNO2) is one of the most inorganic salts and is often used in processed meat products. Long-term consumption of sodium nitrite has been reported to cause of oxidative stress and spleen histological changes. Therefore, anti-oxidative effects are needed from natural ingredients such as Acorus calamus L. The study aims to determine the effect of A.calamus L. rhizome extract on anatomical structure and histological changes in the rat spleen induced with NaNO2. We used a completely randomized design with twenty-five male rats divided into 5 groups. Negative control (NC) was given 0.5% CMC for 40 days; positive control (PC) on days 1-15 was given NaNO2 (50 mg/kg BW); on days 16-30 given (50 mg/kg BW) NaNO2 + 0.5% CMC and on days 31-40 given 0,5% carboxy methyl cellulose (CMC). Treatment 1 (T1), Treatment 2 (T2), and Treatment 3 (T3) on days 1-15 were given NaNO2 doses of 50 mg; and; on days 16-30, groups T1, T2, and T3 were given NaNO2 + extract with each predetermined dose (250 mg/kg BW for T1, 500 mg/kg BW for T2, and 750 mg/kg BW for T3). For days 31-40 groups T1, T2, and T3 were given extracts with each predetermined dose. Results revealed that the extract of the A. calamus L. rhizome affects weight, length, and width of the spleen (P<0.05); and bleeding lesions; while having no noticeable effect (P<0.05) and having a noticeable effect on the area of the white pulp (P<0.05). Administration of ethanol extract of A. calamus L. at a dose of 250 mg/kg BW has an impact on improving spleen length; a dose of 500 mg/kg BW has an impact on the weight and length of the spleen; and a dose of 750 mg / kg BW has an impact on improving spleen length, but the size variation is still in the normal category. While extracts at doses of 250 and 500 mg/kg BW have a repair impact on tissue shrinkage in damaged white pulp.

Abstract

The waters of Peninsular Malaysia located between the South China Sea and the Straits of Malacca are greatly influenced by two different monsoons: the Southwest Monsoon (SW) and the Northeast Monsoon (NE). Zooplankton are known to be receptive to any environmental changes. Apart from biotic and abiotic changes, the movement of water currents also has an impact on the distribution and composition of zooplankton, as this group is considered a passive swimmer that is dependent on the movement of water currents. This study was conducted to determine the effect of water movement in the southern waters of Peninsular Malaysia on the distribution of zooplankton. Sampling was done in three main areas: Kukup, Pengerang, and Pulau Besar. A total of 16 stations with three replicates per station were performed using a plankton net with a mesh size of 140µm. Results show that zooplankton in Pengerang recorded the highest with 256.157 ind/ m3, followed by Kukup (132.412 ind/m3) and Pulau Besar (54.066 ind/m3). There were seven dominant species of copepods recorded in this study, namely Acrocalanus gracilis, Bestiolona similis, Euterpina acutifrons, Oithona nana, Oithona similis, Paracalanus aculeatus, and Paracalanus denudatus. Generally, this study has shown a notable relationship between local current circulation patterns and zooplankton distribution.

Abstract

Rhizophora is a genus of mangrove plants that dominates the Banyuurip Mangrove Center. This plant certainly has an anatomical structure as a form of adaptation to high salinity environments. The purpose of this study was to describe the anatomical characteristics of the leaves of the three Rhizophora species as an adaptation form of mangrove plants in the Banyuurip Mangrove Center and the anatomical variations of the leaves between species. This type of research was descriptive observational in the form of leaf anatomy observations using the whole mount method for longitudinal incisions and the paraffin method for transverse incisions. The results showed that there were anatomical variations among the three Rhizophora species in the Banyuurip Mangrove Center including epidermal cell size, number of epidermal cells, cork warts, number of hypodermis cell layers, hypodermis cell size, stomata size, number of stomata, stomata index, and stomata density. The anatomical characteristics of the leaves of the three Rhizophora species which act as a form of adaptation to mangrove plants are the presence of hypodermis tissue which functions to store water and salt to remove salt content in plants when they abort their leaves, low density of stomata and the presence of cuticles on the adaxial surface of leaves which play a role in reducing the rate of transpiration thus maintaining water to support plant development in saline conditions, cork warts which function as a medium for expelling salt on leaves.

Abstract

In Indonesia, Mimosa pudica Linn. (M. pudica L.) is a wild plant (weed) from the Mimosaceace family. This plant is widely used as a traditional medicine for various types of diseases such as insomnia, acute eye inflammation, urolithiasis (urinary stones), fever, and bronchitis. This study aimed to find out the effect of M. pudica leaf extract on the histological damage of the stomach and duodenum of mice. This study used a Completely Randomized Design with 24 male mice, which were divided into control placebo (P0) given CMC-Na 0.5%; and M. pudica leaf extract doses of 200 mg/kg body weight (P1); 400 mg/kg body weight (P2); and 600 mg/kg body weight (P3). The extract was administered orally for 28 days. On day 29, the animal was dissected to collect its digestive organs. The histological preparation of the stomach and duodenum of mice was performed by using the paraffin method and Hematoxylin and Eosin staining to observe the histological damage, namely congestion, hemorrhage, epithelial cells desquamation, inflammatory cell infiltration, edema, and hyperplasia. Quantitative data were analyzed with a one-way ANOVA test and Duncan's post hoc test with the SPSS version 22. The results showed that the M. pudica leaf extract increased hemorrhage and hyperplasia damage at doses of 400 and 600 mg/kg body weight in mice’s duodenum.

Abstract

Ferns are significantly dominant in Indonesia. The waterfall area is one of the ferns habitats. This study aims to determine the diversity index of ferns species in the Tourism Area of Sekar Pudak Sari Waterfall Wonosalam District, Jombang Regency, East Java. This research was exploratory, descriptive. Data collection uses a single plot measuring 20x20 m at 500 masl, 700 masl, and 900 masl. Each observation plot has a sub-plot with a size of 2x2 m. Data analysis used the Shannon-Wiener diversity index (H'), the taxonomic diversity index (Δ), and dominance (Δ*). The exploration results found 28 species from 11 families, 6 epiphytes, and the rest terrestrial. The taxonomic diversity index in plot 1 was 23.36 (low category), while plots 2 and 3 were 30.58 and 31.66 (medium category). This shows that the environment in the three plots is classified as stable, as indicated by the presence of ferns at various taxonomic levels. The highest dominance diversity index (Δ*) was 2.8 in Plot 2, while Plots 1 and 3 were 2.7 (low category). The total number of individual ferns found influenced the difference in the diversity index. The ferns found in the three plots were relatively few, indicating that the environment was classified as less stable. The Shannon-Wiener diversity index (H') in the three plots was 2.9 (medium category), indicating that the distribution pattern of ferns in the environment was balanced. The Sekar Pudak Sari Waterfall Tourism Area is a suitable habitat for the growth of ferns, so conservation efforts need to be made to maintain a balance of species and stabilize the ecosystem.
