Biomass was calculated by weighing the wet weight of the symbiont mushroom mycelium and then tested for antibacterial activity with an extract concentration of 500 µg/disk. The results of this study, namely the weight of F.solani mycelium on MKD + MGV media was 10 grams, the mass of mycelium on MKD media was 9 grams, while the mass of mycelium on MEB standard media was 9.7 grams. The yield weight of the F.solani crude extract cultured on MKD + MGV media was 0.0386 grams or 0.3860% of the wet weight, on MKD media it showed that the crude extract weight was 0.0276 grams or 0.3067% of the wet weight, while on MEB the crude extract weight was 0.0119 grams or 0.1190% of the wet weight. The results of the antibacterial test showed that the largest inhibition zone for MDR (Meticilin Resistant Staphylococcus aureus) bacteria was F.solani crude extract cultured on MKD + MGV media, namely 25.83 ± 3.37 mm, F.solani cultured on MKD media of 22.10 ± 2.51 mm , while F. solani cultured on MEB media was 19.00 ± 0.52 mm. The results of the mass culture of the fungus Fusarium solani on modified media showed that the mushrooms cultured on MKD + MGV media had greater biomass, crude extract and antibacterial activity compared to MKD and MEB culture media.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130651127","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}

The local rice in South Solok Regency is a type of rice that can potentially be developed for germplasm conservation. One genetic resource that needs to be developed is abiotic and biotic resistance to conserve germplasm so that the local rice plants in South Solok can be maintained on certain lands. The first step that must be taken in conservation efforts is to find, identify and collect local rice genotypes in South Solok Regency. This study aimed to explore and characterize the morphology of local grain and rice in Solok Selatan Regency. This study used a survey method, and the exploration location was determined by purposive sampling. The survey results found 18 local South Solok rice genotypes from four sub-districts. The results of grain morphological characterization showed differences in quantitative properties (length, width, thickness, and weight of 100 grains of grain and caryopsis and grain tail length) as well as differences in qualitative characteristics (lemma and palea color, rice color (caryopsis) and shape, rice (caryopsis). Dendrogram results from cluster analysis of 18 local rice genotypes of South Solok, the coefficient of similarity was between 0.27 – 0.64 (27 -64%) with the highest similarity coefficient of genotypes G013 (rambuman variety) and G016 (redek sangir variety) with a value of 0.64 (64%).","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127916006","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}

This study aims to determine the physicochemical quality of water and the community structure of phytoplankton in the Bongkok River during the dry and rainy seasons. The survey method was used at three stations and 9 observation points in both seasons. Phytoplankton types are identified up to the species level. The physicochemical factors observed included temperature, transparency, water flow, pH, salinity, dissolved oxygen, dissolved carbon dioxide, and levels of nitrate and phosphate. The community structure is seen from the abundance, diversity, uniformity, and dominance index values. From a physicochemical perspective, the Bongkok River is a brackish water type with relatively low levels of phosphate and nitrate nutrients and high dissolved CO2, but dissolved oxygen is still good enough to support aquatic life. There are 41 phytoplankton species from 6 classes, including Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, Euglenaphyceae, and Xanthophyceae. The phytoplankton abundance in the dry season is higher than in the rainy season but is still at a low to moderate level. The phytoplankton diversity in the Bongkok River is in the medium category (2.46 – 2.67) but has a high evenness (0.72-0.89) and low dominance (0.11-0.18). Overall, the water conditions in the Bongkok River are sufficient to support the life of aquatic biota. However, the abundance of phytoplankton is still at a low to moderate level, especially during the rainy season.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"83 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128175843","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}

This study uses a quantitative descriptive method with observation techniques. There are three research stations, namely station I (rocky and seagrass substrate), station II (sandy and seagrass substrate), and station III (rocky and seagrass substrate). The data obtained were analyzed using the formulation of documents, documents, secrecy and Shannon-Winner domination. The results showed that there were 5 species of sea urchins (Echinoidea) which namely Diadema setosum, Echinothrix calamaris, Tripneustes gratilla, Echinometra mathaei and Salmacis sphaeroides. The species diversity index (H') for the three abnormalities was classified as moderate, namely station I (H' 1,34), station II (H' 1,18) and station III (H' 1,22).

The purpose of this study was to learn about the bioactivity of a combination extract of nutmeg leaf, lemongrass, and bee nests, as well as to determine the efficient mosquito repellent lotion recipe from a combination of nutmeg leaf, lemongrass, and bee nests extract. The maceration process was used for extraction. Total flavonoid content was estimated by comparing it to the flavonoid quercetin. The absorbance value was measured with a UV-Vis spectrophotometer. The concentration of the extract combination in the lotion used was 0%, 2.5%, 5% and 10%. The total flavonoid concentration was found to be 16.67 mgQE/g. The 2.5% formula lotion has a protective power of 22%, the 5% formula lotion has a power of 62.96%, and the 10% formula lotion has a power of 82.41%. From these results, it can be seen that a formula with a concentration of nutmeg leaf, lemongrass, and bee nests as much as 10% can be the most effective mosquito repellent.
