Abstract

The productivity of okra (Abelmoschus esculentus L.) can be improved through the utilization of locally available organic materials, such as a combination of liquid organic fertilizer (LOF) derived from Leucaena leucocephala leaves and rice husk ash. This research aimed to evaluate the effects of the combination of these two organic inputs on the growth and chlorophyll content of okra plants. The experiment employed a factorial Completely Randomized Design (CRD) 4×4 with two factors: concentration of Leucaena-based LOF (0%, 10%, 20%, and 30%) and dosage of rice husk ash (0%, 5%, 10%, and 15%), each with three replications. Observed parameters included plant height, fresh weight, and total chlorophyll content. The results showed that the LOF treatment, rice husk ash treatment, and their interaction had significant effects (p < 0.05) on all three parameters. The combination of 30% LOF and 15% rice husk ash (A3B3) produced the highest values for plant height (62.53 cm), fresh weight (158.93 g), and total chlorophyll content (25.72 mg/L). These findings indicate that the combined application of LOF and rice husk ash can effectively enhance physiological efficiency and vegetative growth in okra plants.

Abstract

The limited phosphorus content in liquid organic fertilizer derived from Samanea saman (Jacq.) Merr. leaves may constrain its effectiveness in promoting the growth of mung bean (Vigna radiata L.). This study aimed to improve the fertilizer's efficacy by incorporating bone meal as a phosphorus source and applying biochar to enhance nutrient retention and soil properties. A 2×5 factorial experiment was arranged in a Completely Randomized Design (CRD), with two treatment factors: biochar application (0 and 100 g per polybag) and fertilizer formulations (control, 100% S. saman leaf extract, and combinations of S. saman leaf extract with bone meal at 25%, 50%, and 75% ratios). Growth parameters observed included plant height, number of leaves, and dry weight. The combination of 50% S. saman leaf fertilizer and 50% bone meal, supplemented with biochar, produced the highest performance, with a plant height of 65.72 cm, 22.06 leaves per plant, and a dry weight of 75.82 g. In contrast, treatments without biochar exhibited significantly lower growth. These findings demonstrate that the synergistic application of bone meal and biochar can substantially enhance nutrient availability and improve the performance of organic fertilizers in supporting mung bean growth.

Abstract

Water environmental pollution has become an urgent global concern, requiring in-depth understanding and appropriate solutions to address its adverse impacts. In the educational context, it is important for students to have a strong science literacy to be able to understand and participate in environmental protection efforts. One of the proposed approaches to improving students’ understanding of water environmental pollution is to use Android-based E-modules in biology learning. This method of research uses a systematic literature review (SLR). The SLR method is carried out in three stages so that it can obtain a combination of literature study appropriate and accurate to the research problem to be raised. The results of the Systematic Literature Review (SLR) conducted to evaluate the effectiveness of developing Android-based E-modules in improving student science literacy in the context of biological learning about water pollution. Through a systematic approach, the study analyses a variety of relevant literary studies to draw strong conclusions about the potential of e-modules in facilitating a deeper understanding of scientific concepts related to water environmental pollution to enhance student involvement in science learning and literacy.

Abstract

This study aims to examine the application of the Outcome-Based Education (OBE) approach in Conservation Biology lectures and its impact on improving students' knowledge, practical skills, and attitudes towards conservation issues in the campus environment. This study uses a quantitative method with an experimental design, where data is collected through pre-test and post-test questionnaires, field observations, interviews, and evaluation of conservation projects carried out by students. The results showed a significant increase in students' knowledge of conservation, with the average post-test score increasing by 30%. Students also demonstrate improved practical skills in designing and implementing conservation projects, such as greening and waste management on campus. In addition, the implementation of OBE has succeeded in fostering a more caring attitude towards environmental conservation, with 75% of students showing a stronger commitment to conservation issues after attending OBE-based lectures. Student involvement in conservation activities on campus has also increased, with 70% of students actively participating in various conservation programs. However, this study also finds challenges related to limited resources and time in the implementation of larger conservation projects. Overall, this study indicates that the OBE approach can be an effective method in improving students' knowledge, skills, and attitudes towards conservation, and can strengthen environmental conservation efforts on campus.
