Abstract

Mikania micrantha is a wild weed that thrives in tropical areas, grows rapidly in areas with high humidity and light intensity as well as in fertile soil. Meanwhile, Indonesia's tropical climate is also a suitable habitat for the breeding of termites and wood decay fungi. This study aims to determine the bioactivity of M. micrantha leaf extract against subterranean termite, Coptotermes curvignathus (Holmgren) and wood decaying fungus, Schizopyllum commune and its optimal extract concentration to prevent termite attack and inhibit fungal growth. The extracts were obtained by drying and mashing of M. micrantha leaves. The leaf powder was sieved with a 40-60 mesh filter and macerated with methanol for 3x24 h. The maceration results were filtered and the filtrate was concentrated using a rotary evaporator. Furthermore, identification of the secondary metabolites of the extract was carried out by phytochemistry. The bioactivity test included anti-subterranean termite and wood decay fungus using Potatos Dextrose Agar (PDA) medium. The results showed that M. micrantha leaf extract affected sample weight loss, termite mortality rates and the growth of wood decay fungi. Furthermore, the concentration of M. micrantha extract was inversely proportional to the sample weight loss and directly proportional to the termite mortality rate. In addition, the concentration of M. micrantha leaf extract had a negative correlation with the growth of the decaying fungus of S. commune therefore, the concentration of the extract was directly proportional to the growth inhibition of fungus. Meanwhile, the 4% extract concentration led to the increase in termite mortality rate above 80% and inhibited fungal growth by 100%. The results suggest that the bio-efficacy data from this study may be used to develop wood protecting systems based on wild weeds which are found in tropical areas.

Abstract

Dillenia serrata Thunb.is a member of the Dillenia clan which is endemic to Sulawesi. D. serrata fruit is a seasonal fruit and can be used as a cooking ingredient as a sour taste, raw material for several food products such as candied fruit and syrup, and has the potential to be processed into chips and jam. Traditionally, the leaves and bark of D. serrata are also used by the local community as a sprue medicine, fever, wound medicine, treating swelling or inflammation and treating vomiting of blood. It is believed that there are still many untapped benefits from this plant. This study was conducted to determine the effectiveness of D. serrata fruit extract as an antimicrobial that causes disease in humans, and to determine its effectiveness as an antioxidant. The antioxidant test was carried out using the DPPH method while the antimicrobial test was carried out by the agar diffusion method (Kirby-Bauer). The ripe Dillenia fruit was extracted using methanol, the extract was then diluted in various concentrations for the DPPH test The results showed that the D. serrata extract had the ability as an antioxidant. The antioxidant activity of fresh fruit extracts was higher than that of dried fruit extracts. D. serrata extract is effective in inhibiting the growth of Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus mutans bacteria.

Abstract

The COVID-19 is an illness caused by SARS-CoV-2 that has ended up a widespread since March 2020 as declared by WHO. This condition gives a huge impact on miscellaneous sectors enforcing advance use of technology and information system, especially in scientific and medical community. Bioinformatics as a multidisciplinary method plays important role to overcome the COVID-19 outbreak in the early-stage through data exchange in virtual databases. There are a number of free access databases containing basic to complex information of SARS-CoV-2, such as genetic data sequence, epidemiology, evolutionary analysis, pharmacology, and so on. Bioinformatics allows us to analyze the data further to reveal new information applied in biomedical technology activities. Thus, bioinformatics helps the scientists, clinicians, and government learn the genomic characteristics of SARS-CoV-2, to trace the SARS-CoV-2 spread, and select and develop biomarker for reliable diagnostic tools, and design the drug and vaccine for SARS-CoV-2. This review aims to view insights on uses of bioinformatics methods and the databases related to SARS-CoV-2

Abstract

The bioplastic can be made from sago flour and known as sagoplast. It was widely known that for making bioplastic, the addition of acetic acid and glycerol are needed. Products that are air-dried are easy to grow fungi within a few weeks. This makes the basis for researchers to undestand more about the character and identity of the sagoplast degrading fungi. Characterization and identification were carried out by observed morphology and analyzing the 18SrDNA gene sequence of fungal isolates that had grown on the sagoplast. Fungal isolates morphology showed yellowish-orange color with white thread-like mycelia and a blackish brown mace with white thread-shaped mycelia. These characters of fungal morphology that similar with Aspergillus. The gene sequences of the fungal isolates were aligned with reference gene sequences of the fungi obtained from the Gen Bank of the National Center for Biotechnology Information (NCBI). Sequence data analysis was performed by using the Clustal X program to determine the kinship and taxonomy of the fungal isolates that able to degrade sagoplast. The result showed that two fungal isolates, DFSP.J1 and DFSP.J4, were found and demonstrated their ability for degrading sagoplast. Isolate DFSP.J1 is related to Aspergillus flavus strain PSU2 LC127086.1, while isolate DFSP.J4 is related to Aspergillus niger IFO4033 D63697.1.

Abstract

The toxicity of metal to living organisms, including human beings, was discovered a long time ago. In the present time, aluminum exposure is widely used for wrapping food to keep it taste and smell. However it will affect to human health security, specially the brain. This study aimed to investigate the changes of histological Structure on the cerebral cortex caused by aluminum chloride. The mice were injected intraperitoneally with AlCl3 200 mg/kg body weight, once every 3 days, totalizing 10 administrations. Control only was administration distilled water. Histological observations were carried out using the paraffin method. The results of this study show that aluminum chloride cause disorganization of the laminated cerebral cortex, vacuolization, karyolysis, congestion, and hemorrhage. The mice of one and two-months of age group were more susceptible to aluminum chloride than the mice of the three-months of age group. This research can apply for an assessment of the exposure risk to heavy metal. Increasing Al contamination can occur naturally or by anthropogenic activities. The accumulation of the heavy metal in the organism can occur by biomagnification, by which heavy metal is passed from one trophic level to the next within a food web. Therefore communities that live in urban areas potentially exposed to metals aluminum and should be more concerned related to understanding health risks. Further studies are needed to examine the above matters. We recommend calculating the Provisional Tolerable Weekly Intake of aluminum and implication on local people

Abstract

Begonia is very popular as a foliage plant and some begonia species grow up in pots. Begonia serratipetala and Begonia muricata are Indonesian begonia species that are well suited as indoor potted plants because of their leaf color and shape. In addition, the Bali Botanical Garden's landscape nursery would like to use these begonias for decoration in all buildings. However, it still needs to be studied how long the shelf life of the two begonias is in indoor environments in the highlands without air conditioning (AC). The aim of this study was to investigate the indoor shelf life of B. serratipetala and B. muricata. This research method consists of two steps. The first step was the acclimation phase and the second step was the indoor placement phase. Each begonia was repeated three times. Parameters studied included plant growth (plant height, leaves, leaf width, and leaf length) and environmental factors (sunlight intensity, air temperature, and humidity). The data were analyzed descriptively. Correlation analysis was used to determine the relationship between growth parameters and environmental factors. The result showed that both begonias (B. muricata and B. serratipetala) have similar persistence to indoor begonia species within two weeks, the ideal time for plant replacement

Abstract

Parmentiera cereifera Seem. is an endangered species in the family Bignoniaceae. Related to the conservation effort, information about the reproductive biology of this species is very limited. Based on that, the objectives of this study were to provide knowledge about the reproductive properties such as floral biology and breeding system of P. cereifera. The research was conducted at Purwodadi Botanic Garden, from October 2019 to February 2021. Several important aspects of reproductive biology, including flower biology, pollen viability and stigma receptivity, pollen morphology and breeding system were investigated. The viability was tested with TTC (2, 3, 5–triphenly tetrazolium chloride) and stigma reseptivity was tested with hydrogen peroxide. The breeding system was determined based on outcrossing index (OCI) using Cruden's method. The results showed that P. cereifera flower was monoecious, had morphological character that supported nocturnal pollination. Stigma and anthers spatially separated, but there was no temporal separation of stigma receptivity and anther dehiscence. Based on the flower biology, the pollen ornamentation (reticulate type), and the Out-Crossing Index (OCI=4), the breeding system was outcrossing but partially self-compatible, required pollinators (zoophily)
