Abstract

Copyright©2023 Liquid soap with the active ingredient kombucha butterfly pea can limit the growth of Staphylococcus epidermidis and Pseudomonas aeruginosa bacteria. The purpose of this research was to create a liquid bath soap with the active ingredient fermented liquid from the kombucha flower of the butterfly pea plant that inhibits the development of the two test bacteria and to provide objective data on the maximum inhibitory energy at the concentration of the bath soap preparation that can limit the growth of the two test bacteria. This research was experimental and involved making four different types of bath soap preparations: soap base (negative control), liquid body soap formulated with butterfly pea flower kombucha at concentrations of 20, 30, and 40%, and one of the commercial soaps (positive control). Disc diffusion is the method for measuring the average growth of the two test bacteria. Statistical analysis was a one-way ANOVA statistical test at a 95% confidence level, followed by post hoc analysis. The research showed that the liquid body soap with the active ingredient of telang flower kombucha could positively inhibit the growth of the two test bacteria. The concentration of 40% telang flower kombucha bath soap is the best concentration to limit the development of the two test bacteria, with an inhibition zone of 10 mm on Staphylococcus epidermidis, which is in the strong category, and an inhibition zone of 7 mm on Pseudomonas aeruginosa, which is classified as a moderate category.

Abstract

Copyright©2023 The low interest and motivation in learning that students have during the learning process can be seen by the lack of participation of students in expressing their opinions it affects the learning outcomes of the students themselves. This study aimed to determine the differences in interest, motivation, and learning outcomes of students through the PBL model and the STAD-type Cooperative Learning model. This research was a quasi-experimental study using a pretest-posttest control group design. The sample in this study were students of class XI MIPA taught using the PBL model and the STAD-type Cooperative Learning model. Data collection was carried out by filling out interest, motivation, and learning achievement tests twice, namely the pre-test and post-test. Data analysis was carried out descriptively in the form of N-Gain measurements of normality and inferentially in the form of Normality tests, Homogeneity tests, and independent sample t-Test Hypothesis Tests using the SPSS version 24 system. From the results of this study, it concludes that there are significant differences in interest, motivation, and learning outcomes of students with the application of the PBL learning model and the STAD-type Cooperative Learning model, where the application of the PBL model shows a higher post-test average value than the post-test average value of the STAD Cooperative Learning model so that the PBL model is more effective for use in increasing the interest, motivation, and learning outcomes of students.

Abstract

Tempe starter is a collection of mold spores that have an important role in making tempe because they will affect the quality of the product. In the research conducted, several manipulations were used in the media material for making a starter using several bean mixtures as flour, which aims to compare the quality of the tempe starter and see the effect of adding various types of flour on the quality of the tempe starter made. This study used a completely randomized design (CRD) with 4 treatments and 5 replications. The control treatment was rice (100 g), the first treatment was rice (50 g) + green beans (50 g), the second treatment was rice (50 g) + mung bean (50 g), and the third treatment was rice (50 g). + green beans (25 g) + koro beans (25 g). The results of adding various types of flour to the quality of the tempe starter showed that the composition of the fastest mold growth was treatment 3 (50 g rice + 25 g green beans + 25 g mustard greens) for 31 hours and produced tempe physical properties with a typical white color of tempe. The compact texture does not break easily when sliced with a distinctive tempeh aroma with a combination of green bean and koro bean aromas without any ammonia smell.

Abstract

Copyright©2024 The process of producing tempe produces waste material called waste, which consists of two types: solid and liquid waste. The liquid waste that remains contains numerous organic elements that decompose easily and emit an unpleasant smell. This study was to determine the effect of tempeh liquid waste as an organic liquid fertilizer on the growth of celery (Apium graveolens L). The method used was an experimental method using a completely randomized design (CRD) with a long treatment of tempeh liquid waste fermentation of 3 treatments, namely X0 (control), X1 (2 days of fermentation), and X2 (4 days of fermentation), and 3 replications. The data collection included direct measurements of plant height, number of leaves, and fresh weight, as well as environmental measurements like temperature, humidity, and the pH parameters of tempeh liquid waste. The data obtained were analyzed using analysis of variance (ANOVA). The results showed that X2 treatment (4 days of fermentation) resulted in higher growth of celery plants (stem height, number of leaves, and fresh weight) compared to X0 (dick) and X1 (2 days of fermentation). Practical implications for science from this research include reducing liquid waste, increasing agricultural productivity, developing value-added food products, increasing resource efficiency, and most importantly, it can be an innovation for conducting further research, especially related to liquid waste fermentation and plant growth.

Abstract

Molecular analysis has developed rapidly, one of which is through the application of the DNA barcode method which is supported by the existence of a genetic and molecular data center, namely NCBI. However, there is still no consensus on standard and universal DNA barcode region loci that can be used in plants of various taxa. One of the loci that has been collected in NCBI is psbA-trnH, including data from the genus Momordica. Therefore, this study aims to determine the effectiveness of DNA barcoding with the psbA-trnH in the genus Momordica. The study was conducted by collecting data on psbA-trnH sequence of the genus Momordica in the NCBI database. Sequence data that met the criteria were then aligned and analyzed using MEGA 11 software. The analyzes performed included sequence variation analysis, phylogenetic tree reconstruction based on the maximum parsimony and maximum likelihood methods with bootstrap of 1000x, and the calculation of genetic distance values based on pairwise distance with Kimura-2-Parameters (K2P) substitution model. The results showed that the psbA-trnH region fulfilled the three principles of selecting DNA barcode regions, namely standardization, minimalism, and scalability. The psbA-trnH region has been shown to be able to describe the genetic variation of the genus Momordica both at the interspecies and intraspecies levels, but it is still not effective enough to describe the phylogenetic between taxa, so it needs to be combined with other regional barcode region through further tests and studies.

Abstract

This research aims to determine the instructional needs of the Plant Morphology course. This qualitative descriptive study employed questionnaires and observation sheets to collect the data. The data were analyzed descriptively. The subjects of this study were 24 students majoring in biology in the Biology Science Program, enrolled in the third semester of 2022. According to the research findings, most students rely on online sources for their learning materials, with digital learning materials being the preferred choice for the Plant Morphology course. Students face difficulties in understanding the material and concepts in the Plant Morphology course, mainly because of the use of Latin in this course. The research shows that the teaching and learning activities are ineffective in terms of time because of the extensive material coverage. Several factors contribute to students' difficulties in learning plant morphology, such as the broad concepts, the learning media used, the students' intelligence, and a lack of interest and motivation. The overall teaching activities still rely on PowerPoint presentations. Students neglect reading the materials at home because there is no plant morphology course handbook. The study findings will serve as a reference for developing instructional materials in the Plant Morphology course that align with students' needs, motivating and supporting the achievement of learning objectives
