The purpose of this research was to evaluate the effect of skim milk on sperm motility of Brek fish, Systomus orphoides (Valenciennes, 1842) after 48 hours in 4 ̊C. The method in this research is sperm was collected by hand stripping and was diluted by diluent, which consisted of the fish ringer, skim milk and methanol 10%. The ratio of sperm to diluent is 1:9. The concentrations of skim milk used in this research were 0%, 5%, 10%, 15%, and 20%, respectively. The sperm was stored at 4 ̊C for 48 hours after diluted sperm is thawed in room temperate for 1 minute and sperm motility was observed in improved Neubauer with a light microscope.The motility percentage was analyzed using ANOVA and Tukey test. According to the Annova test (P>0.05), 10% of skim milk showed the highest sperm motility (92.18 + 3.05) % after five replication per dose. Ten percent of skim milk was the optimum concentration to preserve sperm motility at 4 ̊C for 48 hours compared to 0%, 5%, 15%, and 20%. The result of each concentration is 90,85%, 84,68%, 79,54%, and 74,14% respectively.

Vigorous physical exercise that exceeds the limit of fatigue can increase the formation of free radicals that lead to oxidative stress. One of the biomarkers used to determine the presence of oxidative stress is the level of F2isoprostane. This study aims to determine the differences in levels of F2-isoprostan in male model mice (Mus musculus L.) in maximum physical exercise without supplementation. This research is an experiment. The population in this study were 30-35gram male mice aged 8-10 weeks. Based on the provisions in the study, the sample was 30 male mice that met the criteria. Examination of samples using ELISA reader and data processed in tables and graphs. The results of statistical tests obtained p value <0.05 (p <0.01), it can be concluded that there is a difference in F2-isoprostane levels between the groups that were not given weight training and those who were given maximum weight training. Where the levels of F2-isoprostane given maximum weight, training were 2 times greater than those not given weight training.

Phyllosphere bacteria were bacteria that inhabit around the leaf surface. Several studies showed the potential of phyllosphere bacteria in producing bioactive compounds, one of which is antimicrobial compounds. Andaliman (Zanthoxylum acanthopodium DC.) was a plant from the Rutaceae family that was commonly found in North Sumatra, and its fruit was widely used as a spice in traditional cooking by the Batak tribe. Several studies showed that the andaliman terpenoid has antioxidant and antimicrobial activity and an immunostimulating effect. This study aimed to explore the potential of andaliman phyllosphere bacteria. The research design method was a qualitative experimental model. The research stages used in compiling this paper consisted of phyllosphere bacteria isolation, phyllosphere bacteria morphological characterization, and Gram stain. This study succeeded in isolating 206 colonies of andaliman phyllosphere bacteria with various colony forms and cell morphology. From 64 samples of phyllosphere bacterial isolate observed, we found 25 different colony forms, and all samples were Gram-positive bacteria. Microscopic observations of gram staining showed that 44 isolates (68.75%) were cocci, 17 isolates (26.56%) were in the form of bacillus, and three isolates (4.68%) were in the form of coccobacillus.

In anticipating the rapid decrease of energy resource, especially fossil fuel, immediate actions are required to fulfil the needs of highly increased population in the world. Innovation to produce renewable energy from easily utilized raw materials should meet society’s needs including renewable raw materials from wood biomass for energy. Genetically improved Calliandra calothyrsus has been developed for this purpose. Due to low success rate of its reproduction, study on its reproductive biology was undertaken. The study was carried out during the flowering seasons of C. calothyrsus, by examining flower morphology, pollen, and pistil viabilities as wee as insect visitors to this species’ flowers. The study showed that the flowers of C. calothyrsus are borne on inflorescences (spikes) and carrying an average of 354 individual flowers, which develop acropetally. Pistils (female organ) cease to develop by the 2 to 3 day after their appearance, and the flowering is becoming ceased then. Pistils showed maturity during the period of 09.00 WIB 10.00 WIB and pollen is still viable from 1 to 3 days after the pollen opening. Three most frequent visitors (families: Apidae, Vespidae, Formicidae) and one order lepidoptera were found visiting C. calothyrsus flowers However, the reproductive success of C. calotyrsus is found to be very low, which is only 0.024. These preliminary results confirmed that the low reproductive success of C. calothyrsus is due to the structure and development of flowers allowing the incidences of both outcrossing and self-pollination. The limitation time of pistil maturity might also contribute to the low reproductive success of this species.

Some genes play a role in the tissue regeneration process and they have specific functions. One of them is the platelet-derived growth factors (PDGF) gene that have a role in the wound healing process because it induces cell mitosis and thereby causes cell proliferation. PDGF protein expression is thought to chemotactically recruit many cell types including smooth muscle, fibroblasts, and monocytes to migrate to the wound site. These research aims are to analyze the role of PDGF gene expression in the process of digit tip mice tissue regeneration. This study used 24 mice (Mus musculus) were amputated at the digit tip and the growth was observed on days 0, 1, 3, 5, 10, 15, and 25. We isolated RNA from each tissue after amputation on days 0, 1, 3, 5, 10, 15, and 25 and analyzed the RNA expression of the PDGF gene using the qPCR method. PDGF gene expression reached its peak on day 10 on the granule phase and decreased until day 25. The peak expression of the PDGF gene indicates the role of the gene in the tissue regeneration of digit tip mice. The normality test for PDGF gene expression was normally distributed (p> 0, 05) and the variation test between each treatment was different significantly (p <0.05).

Syzygium cumini included in the family Myrtaceae is one type of plant that is hard to find. The benefits of S. cumini plants include seeds as a cure for diabetes, fruit as an antioxidant and anticancer, fruit skin as a medicine for dysentery and leaves as a reinforcement of teeth and gums. This research aimed to study the effect of seed population sources on the growth of S. cumini seedling. Seed exploration was carried out in 3 different S. cumini habitats, (1) Gunungkidul District (2) Yogyakarta District and (3) Cikampek District. CRD (Complete Random Design) was used with each population consisting of three replications (50 seeds/replication). The seed source showed significantly different results on the growth of S. cumini seedlings (height, diameter, number of leaves, wet weight of stem and leaves and dry weight of stem and leaves). However, the variation of seed sources did not significantly differ on survival, root wet mean, root dry weight, top-root ratio and seed quality index. Height, diameter, number of leaves, comparison starting from the greatest were Gunungkidul (30.42 cm / 2.93 mm / 21.42), Cikampek (24.64 cm / 2.82 mm / 21.06) and Yogyakarta (21.27 cm / 2.45 mm / 19.27). While The stem and leaves wet weight and stem and leaf biomass comparison from the highest were Gunungkidul (6.84 gram, 2.10 gram), Yogyakarta (4.95 gram / 1.59 gram) and Cikampek (4.24 gram / 1.47 gram). Moreover, seeds from the Gunungkidul population produced better growth than other populations. This study's recommendation is to develop rare plants of S. cumini species that will have the best growth by using seeds from the Gunungkidul

CRD (Complete Random Design) was used with each population consisting of three replications (50 seeds/replication). The seed source showed significantly different results on the growth of S. cumini seedlings (height, diameter, number of leaves, wet weight of stem and leaves and dry weight of stem and leaves). However, the variation of seed sources did not significantly differ on survival, root wet mean, root dry weight, top-root ratio and seed quality index. Height, diameter, number of leaves, comparison starting from the greatest were Gunungkidul (30.42 cm / 2.93 mm / 21.42), Cikampek (24.64 cm / 2.82 mm / 21.06) and Yogyakarta (21.27 cm / 2.45 mm / 19.27). While The stem and leaves wet weight and stem and leaf biomass comparison from the highest were Gunungkidul (6.84 gram, 2.10 gram), Yogyakarta (4.95 gram / 1.59 gram) and Cikampek (4.24 gram / 1.47 gram). Moreover, seeds from the Gunungkidul population produced better growth than other populations. This study's recommendation is to develop rare plants of S. cumini species that will have the best growth by using seeds from the Gunungkidul","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87529712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
