Abstract

Diaper waste containing the nutrient NPK can increase plant growth. This research aims to find out whether there is an effect of disposable diaper hydrogel on the growth of rose plants (Rosa sp.) and to find out the weight of the hydrogel which has the best effect on the growth of rose plants which is then prepared as a biology learning resource in the form of Student Worksheets. The research used a Completely Randomized Design (CRD) with 1 control and 3 treatments with 4 repetitions. The research was carried out for 2 months with the observation parameters of stem height, number of leaves, and number of petals of roses (Rosa sp.) which were analyzed using the One-Way ANOVA Test for rose plant stem height parameters and the Kruskal Wallis Test for the parameters of number of leaves and number of petals roses. The results of this research show that there is an influence of the weight of disposable diaper hydrogel on the growth of rose plants. It is known that in the analysis of stem height growth data, the calculation of Fcnt = 10.85 > F(0,05) (3,12) = 3.49. Analysis of leaf number data shows that Hcnt = 11.35 > X(0,95) (3) = 7.81. Likewise, analysis of the data on the number of petals shows that Hcnt = 10.04 > X(0,95) (3) = 7.81. The best hydrogel weight was in treatment 3 (P3) for all observed parameters. The results of this research can be used as a learning resource in the form of Student Worksheets on development and growth material in class XII plants.

Abstract

This research aims to produce a product in the form of an integrated Augmented Reality (AR) module that is valid based on design and material validity tests and can facilitate students and educators to learn the biology learning material on the human skeletal system. The method used in this research is research and development with a 4-D (Four D) model which consists of four main stages, namely Define, Design, Develop, and Disseminate. The results of the module assessment by material experts obtained a feasibility percentage of 100% with "very good" criteria. The assessment by design expert validators obtained a percentage of 94.3% with "very good" criteria. Modules that have been developed based on assessments by experts are then tested on students. Students' responses to the module in the language aspect obtained a percentage score of 91.33% with the criteria "very good", in the material aspect they obtained a percentage score of 88% with the criteria "very good", and in the design aspect they obtained a percentage score of 85.67% with the criteria "very good". The module results show that the integrated Augmented reality module developed is suitable for use in the learning process.

Abstract

The objectives of this study are: 1) To determine the benefits of refugia plants (Zinnia elegans Jacq. and Cosmos caudatus) on the intensity of whitefly (Bemisia tabaci) infestation in edamame soybean (Glycinemax (L.) Merrill) plants, 2) To examine the relationship between edamame soybean plant damage (Glycine max (L.) Merrill) and the harvest results, and 3) To evaluate the research results in the form of a poster that is suitable for use as a biology learning resource. This research uses both descriptive qualitative and quantitative methods. The study employs two treatments: edamame soybean fields planted with refugiaplants and edamame soybean fields without refugia plants. The data were analyzed using pest infestationintensity analysis and the Independent Sample T-Test. Based on the research results, the use of refugia plants had a beneficial effect on reducing the intensity ofwhitefly infestations in edamame soybean plants. The intensity analysis showed that refugia plants are effective in suppressing whitefly infestation. Based on T-test analysis, there was no significant difference in the harvest yield of edamame soybeans between fields with and without refugia plants. The validation analysis of the learning resource indicates that this study is suitable as a biology learning resource in the form of a poster.

Abstract

Kepok banana waste, which contains essential NPK nutrients, has the potential to enhance plant growth. This study investigated the effects of combining liquid organic fertilizer (POC) derived from Kepok banana waste with manure on the growth of melon plants (Cucumis melo L.), and identified the optimal dosage for growth performance. The outcomes of this research were further developed into a contextual learning resource in the form of student worksheets for biology education. The experiment was conducted using a Completely Randomized Design (CRD) with four treatments and five replications over a two-month period. Growth parameters observed included the number of branches, the number of flowers, and fresh fruit weight. Data were analyzed using the Kruskal–Wallis test. Results showed significant effects of the POC–manure combination across all parameters: number of branches (H<sub>hit</sub> = 27.55 > χ²<sub>0.95;3</sub> = 7.81), number of flowers (H<sub>hit</sub> = 26.5 > χ²<sub>0.95;3</sub> = 7.81), and fresh fruit weight (H<sub>hit</sub> = 20.58 > χ²<sub>0.95;3</sub> = 7.81). The best treatment for enhancing branch and flower production was P4, whereas P2 produced the greatest fruit weight. These findings confirm that POC from Kepok banana waste, when combined with manure, significantly improves melon plant growth. Furthermore, the study highlights the educational potential of integrating research results into biology learning through student worksheets, particularly for Grade XII on the topic of plant growth and development.

Abstract

The aims of this study were 1) to determine the effect of time variation on preparation endurance, 2) to determine the best time variation on preparation endurance, 3) to determine whether LKPD (Student Activity Sheets) were appropriate as learning resources at school. This type of research is descriptive qualitative experimental research. This study used 4 treatments with 4 replications using a solution of dragon fruit (Hylocereus polyrhizus) and turmeric (Curcuma domestica Val) and 2 positive and negative controls. The positive control used a synthetic dye, namely safranin, and the negative control used no dye. Data analysis in this study was presented in the form of non-statistical qualitative descriptive analysis. Based on the results of the study, the durability of preparations for 0 days showed good tissue staining results, the durability of preparations for 2 days showed results of tissue staining that were still clearly visible, the durability of preparations for 3 days showed results of tissue staining that were no longer clear. The results of this study were declared "feasible" to be used as a medium for learning biology in class XI semester 1 senior high school for exploring cells.

Abstract

This research is motivated by the importance of coffee processing techniques in determining the final taste of robusta coffee beans. Roasting and roasting techniques are two methods that are often used, but each technique has a different effect on the quality of coffee flavor. This research aims to compare the results of processing robusta coffee beans using these two techniques. This research aims to compare the results of roasting and roasting techniques on the taste of robusta coffee beans (Coffea robusta) in Hujung Village, West Lampung. The research method used was experimental with two treatments, namely roasting and roasting techniques. Taste testing is carried out by experienced panelists using organoleptic tests. The research results show that there is a significant difference in taste between coffee beans processed using roasting and roasting techniques. The panelists preferred coffee beans processed using the roasting technique compared to coffee processed using the roasting technique, this is because coffee beans processed using the roasting technique have a stronger aroma and stronger taste compared to coffee processed using the roasting technique, data from This research shows that the average value of the hedonic scale of the panelists' liking for technical roasted coffee in terms of aroma is 4.45, taste is 4.2 and taste impression is 3.75. Meanwhile, for the roasting technique, the average of the hedonic scale for the panelists' liking for the aroma aspect was 3.7, for the taste aspect it was 3.95 and for the taste impression aspect the average was 3.55. This research can be used as a biology learning resource for Class XII high school students on food technology material, especially in understanding processing processes and their influence on product quality.
