Abstract

Background: This study aimed to evaluate the growth ability of cassava mini stem cuttings with different node number and a variety of stem cutting shapes and their correlation with starch content in the stems at initial growth stages. Methods. In this study, the viability of cassava stem cuttings was identified in two type experiments i.e. mini-stem cuttings consisting 1 and 2 nodes and shape variation of single node mini-stem cutting. Parameters observed were shoots emergence period, number of sprouting cuttings, shoots number of individual stem cuttings, shoots height and number of leaves. In addition, starch histochemical test was also carried out on stems of young shoots and initial stem cuttings using Lugol's solution. Results. Both cassava stem cuttings consisting of 1 and 2 buds indicated the same survival rate of 100%. 1 bud stem cuttings with different shapes showed different survival rate, i.e. 60-80% for semicircular and fully circular cuttings and 30-40% for box shape cuttings. The difference in survival rate with different stem size is probably related to the availability of the amount of starch to support shoots growth. Observations at week 3 after planting generally showed that the stem cuttings with 2 buds were higher than those of stem with 1 bud. Conclusion: There were differences in the scores on the starch content test qualitatively with Lugol staining, in various parts of the plant originating from 1 bud and 2 bud cuttings which may indicate a breakdown of starch during shoot development.

Abstract

Background: Gonad differentiation in some teleostei is a critical phase of gonad development. Gonad differentiation in some fish such as the tilapia group is influenced by environmental factors, namely temperature. The aim of this study was to determine the differentiation process of Nilem fish gonads (Osteochilus vittatus) under the influence of temperature. Methods: One day after fertilization (days postfertilization/dpf) fish were exposed to different medium temperature ranges, namely: 28-29 oC, 30-31 oC, 32-33 oC, and room temperature as a control for 35 days. The percentage of fish survival was calculated on the 35th day by calculating the number of surviving fish divided by the total number of fish in 1 tank times 100%. Thirty fish in each treatment were measured for body length at day 10 dpf and day 35 dpf to determine fish growth. Six fish 35 dpf from each treatment were fixed in 70% alcohol for making histological preparations using the paraffin method, Haematoxylin-Eosin staining. Fish survival data growth data in the form of fish length were analyzed using Anova. Gonadal differentiation data were analyzed descriptively. Results: There was no significant difference in the growth of fish in all treatment and control groups. The average survival rate of fish in all treatment and control groups was 100%. Observation of the gonads showed that the gonads were not differentiated in all treatment and control groups. Conclusion: The room temperature range up to 33 oC supports the growth of Nilem fish with gonad development in the indifferent gonad stage.

Abstract

Background: Assessment is a crucial step for determining whether or not a learning process has been successful. High-order thinking skills are a requirement for learning achievement in the twenty-first century. The goal of this project is to put quantitative evaluation instruments created by Jakarta elementary school teachers to the test. Methods: A mix method is used, which combines descriptive qualitative research with document analysis and quantitative research with instrument testing on reproductive system material, which is then examined using Anates. The participants in this study were eight Jakarta-based grade VI primary school teachers. Results: It demonstrates that teachers' capacity to construct evaluation instruments varies widely. Testing using Anates shows 15% of the questions compiled are valid and 85% invalid, 1 school with strong reliability and 7 other schools are less reliable. The difference shows that 42.5% are accepted and 57.5% are rejected. The level of difficulty showed that as many as 8.75% of the questions were in the very easy category, 18.75% easy, 51.25% moderate, 7.5% difficult and 13.75 very difficult. These results form the basis of the importance of the hierarchy of teacher understanding in depth, especially in relation to the preparation of HOTS-based assessment instruments because the quality of learning success is largely determined by the assessment instrument used. Conclusions: The LOTS and HOTS-based capability instruments made by the teacher at 8 East Dijakarta Elementary Schools have not been maximized and need development by these teachers.

Abstract

Background: Biology and the environment have very close interactions in the form of biodiversity, biosphere and ecosystems. The study was systematically conducted on research results articles with the aim of identifying environmental topics in biological education, outlining the research characteristics of biological education and synthesizing research trends and gaps on environmental topics in biological education in Indonesia. Method: Cross-sectional study design is conducted through a survey of research articles published in national journals. Results: The results of a meta-analysis of the structure and content of 41 articles in the indexed journal Sinta 1-3, found environmental pollution was the most discussed topic followed by several other topics such as biodiversity, ecosystems and conservation. Conclusion: Most research uses experimental design and development research with structured instruments to obtain measurable learning outcomes. Therefore, it is necessary to diversify biological education research to focus more on meaningful learning transformation through the integration of biological education in other fields, especially bioculture diversity.

Abstract

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.

Abstract

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.
