Abstract

Propagation of mangosteen is challenging for many reasons, including limited seed set, slow rate of seedling growth, and difficulty with root formations. The objective of this research was to find the best combination of medium and plant growth regulator for in vitro growth and rooting of mangosteeen seed. Various types of explant (a whole seed; seed divided into 2, 3, and 4 cross sections; seed divided into 2, 3, and 4 longitudinal sections) were treated with five concentrations of benzyl amino purine (BAP; 0, 2.5, 5, 7.5, 10 mg/L) for shoot induction in ½ Nitrogen (N) Murashige and Skoog (MS) medium. The shoots were rooted on MS and woody plant medium (WPM) media with several combinations of indole butyric acid (IBA) and naphtalene acetic acid (NAA). Treatments for root induction were applied as follows: (i) low dose, given during induction of rooting, (ii) soaking the base of the shoots in medium treated with a high dose of auxin for 5 days, and then growing the shoots in MS ½ N with 1 mg/L NAA +  1 mg/L BAP medium. Our result show that BAP positively affected mangosteen bud growth. The best medium for mangosteen shoot regeneration was found to be  MS ½ N  + 5 mg/L BAP. This medium induced  the highest number of shoots from the seed explant cut into four cross sections. We found the best medium to induce in vitro rooting of mangosteen shoot was MS ½ N + 3 mg/L indole butiric acid (IBA) + 4 mg/L NAA medium. Some treatment negatively affected growth. Soaking the mangosteen shoot base in a medium with an overly high dose of auxin seemed to disrupt and inhibit growth of the mangosteen shoot.

Abstract

The objectives of this research were to composed organ from callus culture and to found the best concentration of plant growth regulator for organ growth from female flower explant of oil palm. This research has already done from June 2014 to May 2015 at Laboratory of Plant Physiology and Tissue Culture Department of Biology Faculty of Mathematics and Science University of North Sumatera. This research used Nonfactorial Completely Random Design. Explant was treated with five concentrations of 2,4-Dichlorophenoxy acetic acid (2,4-D; 99, 110, 120, 132, and 140 mg/L) for callus induction on Y3 medium (Eeuwens 1976). The result of this research showed that organ was formed from this treatment (basal segment of female flower explant) was root organ. 2,4-D plant growth regulator positively affected to growing of the root. The best result for time of callus induction, time of root growth, the highest percentage of explants that formed the root, fresh weight and dry weight of callus that has become the root generation was resulted from 99 mg/L 2,4-D.   Key words: Elaeis guineensis Jacq., female flower, plant growth regulator 2,4-D, organogenesis

Abstract

The objectives of this research are to analyze the students‟ misconceptions on topicphotosynthesis for each cognitive level and to know if the misconceptions remediation by usinginteractive multimedia and peer tutoringgive effect in decreasing students‟ misconceptionon topicphotosynthesis in SMA Swasta Nurul Iman Tanjung Morawa. Sample of this research are 56 studentsof science class XII. The types of this research are the descriptive research and pre-experimentalresearch with one group pretest-posttest design. The technique of data collecting was the two tiersmultiple choice closed reasoning diagnostic tests, consist of 45 questions which was used as pretestand posttest. The findingsshow that the students getting misconception on topic photosynthesis inhigh category of misconception by percentage 66%. The highest percentage of students‟misconception is at cognitive level 6, by percentage 76%. After treatment the results obtained thatmisconceptions remediation by using interactive multimedia and peer tutoring decrease students‟misconception as many as 47% which is from 66% to 19%. Hypothesis testing showed that tcount(3.969) > ttable (0.05)(55) (1.673), it means that H0 was rejected and Ha accepted. It can be concluded thatstudents‟ misconceptions remediation by using interactive multimedia and peer tutoring give effect indecreasing students‟ misconception on topic photosynthesis in science class XII SMA Swasta NurulIman Tanjung Morawa.Keywords: interactive multimedia, misconception, peer tutoring, photosynthesis

Abstract

This study aims to develop and determine the feasibility of a tissue culture textbook based on scientific literacy, conducted from November 2020 to May 2021. This study used the Dick & Carrey development model, modified to the formative evaluation stage. The instrument used is a questionnaire filled out by validators (material experts, learning design experts, layout design experts), lecturers of the Network Culture course, and students majoring in biology. The results showed that 77% of students had difficulty learning about somaclonal diversity and needed additional cultural application material. There were no scientific literacy-based tissue culture textbooks in the UNIMED library. Based on the survey, 76.9% of students said they liked somaclonal diversity material, 86.6% said it was challenging to study, 53.8% of the material described the interaction of science, environment, technology, and society, 30.8% did not explain the application of culture. As the results of textbook development, validator analysis shows 86% (very feasible) from material experts, 91% (very feasible) from learning design experts and 91% (very feasible) from layout design experts. The percentage of responses showed: 93% (very feasible) from lecturers, 86% (very feasible) from individuals, 90% (very feasible) from small groups and 89% (very feasible) from limited groups. Overall the textbook is very feasible to use.
