Isolation and Characterization of Endophytic Bacteria in Ciplukan Plant (Physalis angulata) Annisa Wulan Agus Utami; Munarti Munarti
Indonesian Journal of Biology Education Vol 3, No 1 (2020): INDONESIAN JOURNAL OF BIOLOGY EDUCATION
Publisher : Universitas Tidar

Biodiversity of endophytic bacteria is a potential biological resource to be applied in various fields, especially in the medical field. Endophytic bacteria are bacteria that live in the host plant tissues which belongs to a symbiosis of mutualism. Ciplukan plant (Physalis angulata) is a herbal plant that is useful as antihyperglycemic, antimicrobe, immunostimulant, anti-inflammatory, antioxidant, and cytotoxic. Active compounds obtained from plants need a more complicated time and process compared to extracting compounds from bacteria. The study aims to obtain isolates and characterization of endophytic bacteria in Ciplukan plant (Physalis angulata). The method that is used is the isolation of microbe by Nutrient Agar (NA), and morphological characterization with a gram staining technique. The result of isolation of endophytic bacteria in Ciplukan plant (Physalis angulata) obtains the data which the highest mean is in the rhizosphere part that is 13.13 x 106. Isolation of a single colony of endophytic bacteria obtains 20 bacterial isolates which are 12 bacterial isolates of Gram-positive and 8 bacterial isolates of Gram-negative. The result of isolation of a single colony obtains 1 bacterial isolate of endophytic root (AC2) that has characteristic as Actinobacteria which has a form of spherical spore of colony and Gram-positive. Actinobacteria colonies grow by attached to the surface of the media and can produce spores such as powder. Metabolite compounds produced by Actinobacteria have the role of inhibiting the growth of bacteria and fungi. Furthermore, the metabolites produced by Actinomycetes are widely developed as medicinal materials that can cope with various diseases.

Self-esteem and negative emotional state have a role in the tendency of students to do academic procrastination in completing the final assignments. This study aims to determine the relationship between self-esteem and negative emotional state with academic procrastination in last year's students — the research conducted at the Biology Education and Biology Department, Jakarta State University, in July 2019. The method used was descriptive correlational. The research sample was 48 Biology students from 2012, 2013, and 2014 who had not graduated on time selected by simple random sampling. The instruments used were the Coopersmith Self Esteem Inventory (CSEI), Depression Anxiety Stress Scale 42 (DASS 42), and academic procrastination questionnaires. The analysis prerequisite test results obtained by data distribution normally and homogeneously. The result is a significant relationship between self-esteem and negative emotional states with academic procrastination in final year college students.

Development of Cyberlink Power Director Based Learning Media in the Material of Human Digestive System Mulyani Rahayu
Indonesian Journal of Biology Education Vol 3, No 1 (2020): INDONESIAN JOURNAL OF BIOLOGY EDUCATION
Publisher : Universitas Tidar

The need for developing Cyberlink Power Director learning media based on poetries and songs for students and teacher includes the need of videos that can be seen, heard well, and can be used repeatedly according to particular time and place. Moreover, the presentation of information can be understood clearly, can contain the contents of the material systematically and comprehensively, can improve students’ learning outcomes, and can investigate the effectiveness of this media for science subject in the material about digestive in human for the fifth graders of MI Muhammadiyah Donorejo, Secang District, Magelang Regency. This research is an R&D (Research and Development) using the ADDIE step. The Technique of data analysis uses the quantitative descriptive technique. The type of instrument used was a questionnaire filled out before and after implementation. The result of this study shows that the Cyberlink Power Director based on poetries and song is proven to be valid by expert, and also effective in improving students’ learning outcomes in science subject in the material about digestive components in human (paired-sample t test, p = 0.00 <0.05).

Publisher : Universitas Tidar

This study aims to examine the arguments of college students who are smokers at Universitas Tidar (Tidar University). The research method used in this study is a survey method with two instruments which are interview and questionnaire conducted in December 2019. The data is analyzed by using descriptive qualitative method. The respondents in this study are 15 college students from some faculties in Universitas Tidar. Based on the result of interview and questionnaire, it shows that in the campus environment, there are some students who know the rules about the prohibition of smoking in the campus environment especially Universitas Tidar. In fact, a research about the argumentation study of college students who are smokers shows that there are still some students who smoke in the campus environment. Moreover, 67% of the college students are not ashamed when the lecturers see them smoking. In addition, the results obtained as much as 100% of respondents know about the negative effects of smoking. However, there are only 67% of respondents who just have the desire to stop smoking and it even has not been realized. They are still smoking with the reason that they still feel the advantages or positive effects of smoking for them. As the example, smoking can increase their morale and reduce stress. They also have not felt the negative effects on their health conditions such as breathless and current finances.

Molecular Identification of Two Rare Actinomycetes Isolated from Mosul, Iraq Talal Sabhan Salih
Indonesian Journal of Biology Education Vol 3, No 1 (2020): INDONESIAN JOURNAL OF BIOLOGY EDUCATION
Publisher : Universitas Tidar

Rare actinomycetes from diverse habitats are continued to be isolated and screened for their novel bioactive compounds. The present study aims to molecular, morphological and physiological characterisation of two rare actinomycetes isolated from an Iraqi soil. Based on the 16S rRNA gene sequencing, the two isolates were categorized into two different rare genera Actinoplanes and Amycolatopsis that were designated as Actinoplanes sp. MOSUL and Amycolatopsis sp. MOSUL respectively. Phylogenetic trees analyses revealed that Act. sp. MOSUL was closely related strain to Act. xinjiangensis (jgi.1107663; identity 96.75%) and Act. lobatus (AB037006; identity 96.76%), and Amy. sp. MOSUL was most related to Amy. bullii (HQ65173099; identity 99.71%) and Amy. tolypomycina (FNSO01000004; identity 99.26%). The two rare isolates had different morphological properties when grown on International Streptomyces Project (ISP) media, and different physiological and biochemical patterns when grown on Minimal Medium (MM) agar alone or supplemented with different carbon or chemical sources. The ribosomal 16S gene sequences of both Act. sp. MOSUL and Amy. sp. MOSUL strains were submitted to the National Center for Biotechnology Information (NCBI) and deposited in the GenBank database under the accession numbers MN095717 and MN095769 respectively.
