Mosquitoes are also known as vectors or transmitters of several types of dangerous and deadly diseases for humans, one of which is dengue fever. Therefore, an alternative is needed to reduce this species. The alternative that can be done is by providing vegetable insecticides. Betel leaf has the potential to be used as a base for making plant-based insecticides that are environmentally friendly because they contain chemical compounds in the form of phenols and derivatives such as chavikol and eugenol, alkaloids, tannins, flavonoids, saponins and essential oils. This study aims to determine the concentration of betel leaf extract (Piper betel L.) which is effective for killing mosquitoes. This study used an experimental method using a completely randomized design (CRD) with 6 treatments and 4 replications, namely KN as negative control group, KP as control positive (100% HIT brand liquid), P1 25% extract, P2 50% extract, P3 75% extract, and P4 100% extract. The number of dead mosquitoes (mortality) were observed after 1 hour of treatment. Data were analyzed using variance analysis (ANAVA). The results of this study were the administration of various concentrations of betel leaf extract (Piper betel L.) significantly (p <0.05) to kill mosquitoes. The greatest frequency of mosquito mortality was found at the P4, the highest extract concentration. The conclusion of this study is that betel leaf extract for 1 hour had a significant effect on mosquito mortality.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73383020","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}

Since the entry into Indonesia, the application of watermelon plant breeding has grown to produce new superior varieties, hence not only able to meet market demand, but also to have implications for the progress of the agribusiness sector and national food security. Watermelon ♀ ‘Maduri’ with ♂ ‘Putri Delima’ cultivar hybrid produce an oblong-shaped fruit, has a dark green skin tone with dark green streaks, orange flesh fruit, and sweet taste. However, to be certified and become a cultivar that can be cultivated extensively, the new varieties need to have an adaptive and stable character. This study aims to determine the phenotype character and stability of watermelon ♀ ‘Maduri’ with ♂ ‘Putri Delima’ cultivar hybrid which is cultivated in Jamusan Village, Prambanan Sub-district, Sleman, D.I.Yogyakarta fields. Furthermore, 1 randomly collected watermelon samples were taken. Then, the qualitative and quantitative characters of samples were observed. The quantitative data were analyzed using Microsoft Excel 2016 with ANOVA single factor test at 1% and 5% level. The result of ANOVA test at 5% significance level shows F value at 0,00055 and Fcrit value at 4,259677273, while at the l% significance level, F value obtained at 0,00055 and the Fcrit value obtained at 7,822871.

However, the potency of the bioactive compounds from red ginger as an antitumor agent has not been reported before. This research aims to study the inhibitory activity of several red ginger bioactive compounds against antitumor AKT1 protein through in-silico analysis. In this study, four identified bioactive compounds namely rutin, sitosteryl 3-O-6-palmytoil-β-d-glucoside, kumatakenin, kaempferol-3-o-glucuronide were used as a ligand for molecular interactions. The 3D structure of targetted protein AKT1 (PDB ID: 3O96) was obtained from the PDB database. [6]-shogaol, an antiproliferative and AKT1 inhibitor, was used as a control. In-silico docking analysis is performed in PyRx with the AutoDock Vina program. All bioactive compounds used in this experiment demonstrated good antitumor activity by binding to the inhibitor site of AKT1 protein. Rutin displayed the best potency as an inhibitor to AKT1 with the optimum binding energy of 11,3 kcal/mol as compared to control with -7,4 kcal/mol. These results suggest that bioactive compounds from red ginger may have the potency as an antitumor and can be developed to treat cancer.","PeriodicalId":20665,"journal":{"name":"Proceedings of the 3rd KOBI Congress, International and National Conferences (KOBICINC 2020)","volume":"404 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74348376","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}

DNA isolation, DNA amplification, and electrophoresis are carried out in the biotechnology laboratory, Department of Biology, University of Bengkulu. The meat samples that had been milled were then performed genome DNA isolation following the Qiagen DNeasy for Food Kit protocol. PCR (Polymerous Chain Reaction) is carried out as many as 30 cycles with Primer Forward referring to and primary Reverse Mix (pork, cow, and chicken), Reverse Pork for pigs and Reverse cow for cows. PCR products are electrophobic on 1% agarose gel and then visualized under UV light using Gel Document System Axygen. As a result of the study, on the primary use of Rcow all samples contained cow DNA. In primary use reverse pork, no DNA tape is amplified. In the primary use of Reverse mix from ten samples all containing cow DNA, one sample is thought to contain pig DNA i.e. s7 samples, and six of them contain chicken DNA (S1, S4, S5, S6, S7, and S8).
