Background: The ability to think analytically is one part of higher-order thinking skills, which should be owned by students according to the reference in the curriculum. Giving feedback is one of the efforts to support students' analytical thinking skills. Methods: The research used is Quasi-Experimental, with a Posttest-Only Control Design. The sampling technique used was Cluster Random Sampling. The research instrument was used through a test in the form of a description of 6 questions integrated into three indicators of analytical thinking ability (Differentiating, Attributing and Organizing). Results: showed that the average value of posttest analytical thinking ability in the experimental class was 63.67, which was greater than the control class, which was 56.63. Hypothesis testing through t-test at the 5% significance level obtained the value of tcount = 2.13 while ttable = 2.00, it is mean that tcount > ttable then H0 is rejected. Conclusions: The conclusion that can be formulated is that giving feedback has a significant effect on students' analytical thinking skills on the excretory system material, with the highest achievement indicator of analytical thinking ability achieved by indicators attributing.

Background: Family of Anisakidae is one of the zoonotic helminth parasitics. The distribution of the family Anisakidae is extensive. It needs to be known because the diversity of parasites can provide information about the distribution area and impact of the parasites of the family Anisakidae in Indonesia. This review article summarises the distribution of parasites from the family Anisakidae that infects marine fish and the factors that influence Indonesia. Methods: This research is qualitative research through literature study as the main object. The data from the literature study results are presented in tables and figures then explained descriptively. Results: The distribution of Anisakidae in Indonesia is found in four genera, namely the genus Anisakis, Pseudoterranova, Terranova and Contracaecum, which are mostly found from the carnivorous marine fish of the family Balistidae, Carangidae, Epinephelidae, Lutjanidae, Priacanthidae, and Scombridae Conclusions: Four genera of endoparasitic worms from the Anisakidae family were reported to infect Indonesian marine fish, including Anisakis, Pseudoterranova, Terranova and Contracaecum. Temperature, salinity, hosts' presence, and anthropogenic factors are biotic and abiotic factors that can affect the distribution of Anisakidae. The information on this literature study results is hoped to be used as the basis for developing research in fish parasitology in particular and increasing public awareness of fish processing in general.

Background: Preparing requires colouring to clarify or sharpen various tissue parts, especially cells. The use of synthetic dyes in preparations in the long term can less impact both living things and the environment. The study aims to obtain natural dyes from morning glory flowers at optimal temperatures and pH and find out the feasibility of preparations coloured using Morning Glory flower extract. Method: The extraction process uses a maceration method with different temperature variations of 400C, 500C, 600C, 700C, 800C and different pH i.e. 3, 4, 5, 6. The preparation process uses different dye concentration variations. The concentrations used are 50%, 60%, 70%, 80%, 90%, 100%. Data analysis techniques use descriptive and percentage analysis methods. Results: Morning glory flower extract (Ipomoea purpurea (L.) Roth) can colour dermal tissue, empulur, cortex and transport beams on the stems of cayenne pepper plants (Capsicum frutescens L.). Conclusion: Natural dyes of morning glory flowers can be used as a learning medium with a 74% eligibility rate for preparing with morning glory flower dyes.

Background: Hydroponics is a method of agriculture that utilizes water as a planting medium. The purpose of the study was to find out good working procedures and nutrient solution formulas capable of showing symptoms of morphological nutritional deficiencies in plants. Methods: The plants used are the seeds of kale plants that are sown within 1 - 2 weeks (until roots, stems, and leaves grow). The design used is Random Group using three formulas with nine kinds of treatment on each formula and three repeats. Experiments were conducted on two hydroponic systems, the axis and without the axis. The parameters observed are the number of leaves, the leaves' length, the leaves' width, the plant's height, and the plant's height. Results: Observational data in the analysis using SPSS 25. The effect of treatment with test parameters is seen using ANOVA analysis and BNT advanced tests. Visual observations showed the formula of nutrient solutions 1, 2 and 3 using both the axis system and without the axis showed symptoms of nutritional deficiencies in kale plants. The axis less system experiment gave more significant results on all parameters except PD (leaf length) than the axis system based on the average results of BNT advanced tests. Conclusion: Nutrient solutions 1, 2 and 3 have a real effect on all test parameters.

Background: Arenga vinegar (Arenga pinnata) has been trusted by the indigenous people of Kampung Kuta as traditional medicine, one of which is used as a diabetes medicine. For this reason, the aim of this study is to examine the bioactive compounds contained in arenga vinegar, namely acetic acid, which is predicted to be scientifically proven using reverse docking techniques. Methods: This research is descriptive qualitative research, by interpreting the data obtained from databases and software. Results: There is a binding pose between acetic acid and the sucrase-isomaltase enzyme, the lowest binding affinity value is -3.2 kcal/mol, and the binding site occurs hydrophobic interactions with the amino acids Trp327 (A), Asp355 (A), Ile392 (A), Trp470 (A), Phe604 (A), His629 (A), Trp586 (A) as well as hydrogen bonding to the amino acid Asp(472)A. Conclusions: The acetic acid-binding pose binds well to the sucrase-isomaltase enzyme so that the binding affinity value appears even though the value is not too low and the binding site occurs, this can be used as proof of the belief of the indigenous people of Kampung Kuta, namely the treatment of arenga vinegar as a diabetes drug, especially as a level control blood sugar.

Background: Entomopathogenic fungi are one of the potential biodiversity assets to be used as biological control agents. However, information about the diversity of entomopathogenic fungi, especially in the Gunung Tukung Gede (GTG) nature reserve is very limited. The purpose of this study was to provide information on the biodiversity of entomopathogenic fungi in the GTG nature reserve. Methods: The entomopathogenic fungi were explored from 3 different stations: primary forest, secondary forest and disturbed forest. Entomopathogenic fungi were isolated identified both macroscopically and microscopically. Results: A total of 15 specimens of entomopathogenic fungi consisting of 5 families and 8 types of fungi successfully isolate. The entomopathogen fungi were Basidiobolus haptosporus, Beauveria bassiana., Metarhizium aniesophalie, Paecilomyces sp., Aschersonia sp., Aspergillus sp. 1, Aspergillus sp.2, and Septobasidium sp. These fungi infect insect hosts from the orders Lepidoptera, Hemiptera and Homoptera. The index of the diversity of entomopathogenic fungi at 3 consecutive stations is 1.5495; 1.3322; and 0.6365 (medium category). Conclusions: The GTG Nature Reserve has a unique diversity of entomopathogenic fungi. Therefore, further research is needed in order to determine the diversity and potential utilization of the existing entomopathogenic fungi.

Background: Breadfruit [Artocarpus altilis (Parkinson ex F.A.Zorn) Fosberg] is a versatile plant that can be used by humans. Breadfruit has morphological variations that are thought to be related to anatomical variations that are formed as an adaptation mechanism to survive in a different area. This plant has the ability to live in different altitude ranges, from coastal areas to upland areas. This research was conducted for eight months in areas with altitude ranges of <350 masl, 350-700 masl, and >700 masl in Banyumas, Purbalingga, and Cilacap Regencies. Sampling of plants was carried out randomly selected (purposive random sampling), then described their morphological characteristics. Furthermore, the leaves are made for anatomical preservation to determine the anatomical character. Breadfruit plants that grow at an altitude of less than 350 m above sea level have the characteristics of a higher, larger diameter stem, have a tighter branching, more sap production, a higher number of fruit and have a larger fruit size. The anatomical characteristics of breadfruit plants that grow at an altitude of less than 350 masl have stomata characters that are wider and longer than those of 350-700 masl and > 700 masl. The highest stomata and trichomata density at an altitude > 700 masl. The highest mean cuticle thickness, epidermis, palisade ratio and mesophyll thickness were highest in breadfruit leaves at altitudes <350 masl.

Furthermore, the leaves are made for anatomical preservation to determine the anatomical character. Breadfruit plants that grow at an altitude of less than 350 m above sea level have the characteristics of a higher, larger diameter stem, have a tighter branching, more sap production, a higher number of fruit and have a larger fruit size. The anatomical characteristics of breadfruit plants that grow at an altitude of less than 350 masl have stomata characters that are wider and longer than those of 350-700 masl and > 700 masl. The highest stomata and trichomata density at an altitude > 700 masl. The highest mean cuticle thickness, epidermis, palisade ratio and mesophyll thickness were highest in breadfruit leaves at altitudes <350 masl.","PeriodicalId":33216,"journal":{"name":"Bioeduscience","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48160851","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}
