Abstract

Pepe River is one of the Bengawan Solo with a reasonably high level of water pollution due to the habit of the surroundings in throwing garbage into the river. Plants that can survive in polluted land conditions have a high tolerance level, called pioneer plants. One of them is ferns (Pteridophyta). This study aims to identify the type, abundance, Important Value Index (IVI), and index Diversity of pteridophytes plant diversity in the Pepe Watershed. The method used in this research is descriptive quantitative using the quadrat sampling technique method with a 1x1 meter plot. The sampling technique is using purposive sampling. Data analysis was conducted qualitatively and quantitatively. Analysis of diversity index data (H’) by Shannon-Wiener. Based on the results of the study found eight species of ferns from 5 families. There are Pteris vittata, Pteris biaurita L., Adiantum lunulatum Burm.fil., Adiantum latifolium Lam., Adiantum hispidulum Sw, Marsilea crenata C. Presl, Microlepia speluncae (L.) T. Moore, and Asplenium scandicinum Kaulf. Thisdiversity is included in the medium category with H'= 1.44. The fern with the highest abundance was Pteris vittata with 176 individuals, a density of 5.87 individuals/m2, a frequency of 0.53, and an IVI of 109.3%. Set side by set, the lowest abundance was Microlepia speluncae with eight individuals, a density of 0.27 individuals/m2, afrequency of 0.03, and IVI of 5.6%. Based on this, ferns can survive in polluted river areas. Information on the diversity of ferns found on critical land, especially rivers, is expected to provide initial information in overcoming other similar critical lands.

Abstract

Four endophytic bacteria have been isolated from banana kluthuk plants and banana ambon. Previous study showed that they produce Indole Acetic Acid (IAA). This study aimed to analyze the effect of endophytic bacterial inoculation on plant height and the number of rice root. For this reason, two endophytic bacteria of each klutuk banana and ambon banana plants were cultured and examined for growth rate using a 600 nm spectrophotometer. Isolate growth was calculated every two hours for 16 hours of bacterial growth in NB media. Bacterial inoculation experiments on rice plants were carried out with five replications. This inoculation begun with germination of rice seeds until the radicle was observed. Then germinated rice seedlings were soaked in a bacterial suspension for 1 hour at room temperature. The results showed the exponential phase of all isolates was observed at 6 hours with shaking. Inoculation using A22 and A51 isolates significantly increases plant height, number of leaves. While, A22 isolate significantly increased the number of roots compared to the uninoculated plants (control). It supports the potential of endophytic bacteria from banana kluthuk and ambon plants.

Abstract

Questionnaires are commonly utilized on educational research. However, studies on Differential Item Functioning (DIF) and calibration using Rasch Models are still limited. Therefore, a Self-regulated Learning questionnaire was developed which aims to determine the ability of students to regulate themselves to achieve learning goals. The instrument consists of twelve items. The involved participants were 300 students who enrolled in first-year to fourth-year. Data were analyzed using Racsh Model Analysis with Winsteps 4.5.2 software. As a result, there are four items that were not fit, so that, therefore should be eliminated or revised. The DIF analysis found that gender bias was unidentified, but long-study bias was detected for items number one and six. The reliability value of the item is categorized as very good (0.99), which indicates that the instrument has sufficient consistency/reliability. While, the function curve showed that the items on the self-regulated learning questionnaire produce optimal information in individuals with moderate (θ) ability. Overall, self-regulated learning questionnaires have to be revised then tested on different sample groups. In addition, longitudinal and cross-sectional research is necessary to determine the level of self-regulated learning of students more comprehensively.

Abstract

The bacteria found in the rhizosphere are called plant growth promoting rhizobacteria (PGPR), namely bacteria that can stimulate plant growth by producing growth hormones, one of which is the hormone indole acetic acid (IAA) which plays a role in regulating plant growth and development. Five isolates of rhizosphere bacteria were isolated on frangipani roots (P26, P31, P36, P37 and P38). Previous research showed that five bacterial isolates were capable of producing the hormone IAA. However, evidence of its potential as a PGPR has not been obtained. Therefore, the aim of this study was to test the effect of inoculation of rhizosphere bacteria on maize plants. The research method uses a quantitative experimental method, namely 15 repetitions for each treatment. Data collection was carried out 1 day after planting (HTS) until the 14th day. Data were analyzed using a 95% confidence student t-test or with a significance level of 5% (a=0.05). This inoculation begins with germinating maize seeds and observing the roots. The germinated maize seeds are then soaked in the bacterial suspension for one hour at room temperature. The results showed that inoculation with isolates P36, P37 and P38 significantly increased the height of maize plants, while isolate P37 significantly increased the number of leaves and root length of corn plants, isolate P38 could significantly increase the number of roots of corn plants.Thus, these results support the evidence that rhizosphere bacteria from frangipani have an effect on increasing the growth of maize plants

Abstract

One of the issues in biology education is the low level of students’ critical thinking skills. This is primarily due to conventional, teacher-centered learning approaches that do not allow students to develop their thinking. Therefore, innovative teaching strategies are needed to enhance students’ critical thinking abilities, like the discovery learning model integrated with reflective learning journals. This study aims to investigate the impact of the discovery learning model integrated with reflective learning journals in improving students’ critical thinking skills, including an analysis based on high and low academic abilities. This quasi-experimental study employs a pretest-posttest control group design. The sample was selected using cluster random sampling at SMA Negeri 2 Karanganyar, with class X-E8 as the control group and class X-E6 as the experimental group. Primary data was collected with observation sheets, tests, and documentation. Hypothesis testing was conducted using ANCOVA and N-Gain tests. The findings indicate significant differences in students’ critical thinking skills on environmental changes when taught using the discovery learning model alone compared to the discovery learning model combined with reflective learning journals. Moreover, differences were observed based on students’ high and low academic abilities. Combining the discovery learning model with reflective learning journals enables students to identify and formulate problems based on observed phenomena, determine learning objectives, gather data, draw conclusions, and articulate their thoughts through reflective journal writing. This instructional approach is used for broader implementation and further investigation to assess its impact on other learning outcomes.
