Abstract

Biology learning at the senior high school level requires the support of interactive learning media to help students understand complex and abstract biological concepts. This study aims to analyze the need for interactive biology learning media among tenth-grade students at SMA Negeri 5 Tuban. A quantitative descriptive method was employed, using non-test data collection techniques in the form of questionnaires and teacher interviews. The instrument was developed using a Guttman scale (Yes/No) consisting of 15 items grouped into three aspects: learning media needs, accessibility and ease of use of learning media, and learning motivation and interest. The subjects of this study were tenth-grade students of SMA Negeri 5 Tuban. Data were analyzed descriptively to determine the level of students’ needs for interactive biology learning media. The results showed that the learning media needs aspect reached 92%, accessibility and ease of use reached 85%, and motivation and learning interest reached 99%, with an overall average of 92%, categorized as a very high level of need. These findings indicate that students have a very high demand for interactive biology learning media, highlighting the importance of developing interactive biology learning materials that align with students’ needs and characteristics.

Abstract

The increasing intensification of dragon fruit (Hylocereus sp.) cultivation is followed by an increase in disease attacks that have the potential to reduce plant productivity. This study aims to isolate, identify, and test the pathogenicity of bacteria that cause dragon fruit stem rot in Pematang Donok Village, Kepahiang, Bengkulu. Bacterial isolation was carried out from disease-infected stem tissue, followed by isolation purification. Bacterial identification was carried out based on colony morphology and Gram staining, while pathogenicity and hemolysis tests were carried out on potatoes and blood agar media, respectively. The data were analyzed descriptively qualitatively through observation of colony morphological characteristics and Gram staining, as well as pathogenicity tests on potatoes and hemolysis tests on blood agar. The isolation results obtained two bacterial isolates, namely isolates BBNK1 and BBNK2 with different colony morphology characteristics. Both isolates are Gram-positive bacteria with bacillus and coccus cell shapes. Pathogenicity tests on potatoes showed that both isolates were able to cause soft rot symptoms such as tissue softening, discoloration, and mucus formation compared to the control. Hemolysis tests showed that only isolate BBNK1 showed hemolytic activity with the formation of a clear zone around the isolate. The findings of this study offer foundational data to support future research on molecular identification and the development of more environmentally friendly and sustainable disease management strategies.

Abstract

Twenty-first-century education and the Merdeka Curriculum call for deep learning-based instruction that fosters deep conceptual understanding, making teacher readiness a key factor in its successful implementation. This study analyzes science teachers' readiness in implementing deep learning-based instruction within the Merdeka Curriculum at SMPK Renha Rosario Kewapante, viewed from knowledge, skills, resource availability, and attitude. A descriptive qualitative approach was used, involving one science teacher as the main informant, supported by the principal, the vice-principal for curriculum, and two peer teachers selected through purposive sampling. Data were collected through questionnaires, semi-structured interviews, observation, and documentation, validated through source and technique triangulation, member checking, and referential adequacy, and analyzed using data reduction, display, and conclusion drawing. Results show teacher readiness is good in knowledge, skills, and attitude, and fairly good in resource availability. The teacher understood the Merdeka Curriculum and deep learning concepts and could design lesson plans based on mindful, meaningful, and joyful learning principles, yet classroom practice remained dominated by lecturing, indicating a gap between conceptual and implementative readiness. Supporting factors included school support, collaboration through learning communities and subject teacher forums, and student participation, while inhibiting factors included limited facilities, time, and sustained professional mentoring. These findings imply the need to strengthen academic supervision, practice-oriented training, and learning facilities to bridge this gap.

Abstract

Feed accounts for approximately 60–70% of the total production cost in broiler farming. The dependence on conventional feed ingredients, many of which are supplied from outside the region or imported, highlights the need to utilize locally available feed resources as a more economical and sustainable alternative. This study aimed to formulate broiler diets based on the potential of local feed ingredients in Sikka Regency using a precision nutrition approach. The research was conducted for one month at the Animal Science Laboratory of Universitas Nusa Nipa using an experimental method with a descriptive-quantitative approach. The research stages included the identification of local feed resources, nutrient evaluation based on literature data, diet formulation according to broiler nutrient requirements, and optimization of ingredient composition using Microsoft Excel Solver. The identified feed ingredients included local maize, rice bran, corn bran, fish meal, tofu by-product, coconut by-product, Moringa oleifera leaf meal, Gliricidia sepium flowers, Leucaena leucocephala seeds, sorghum hulls, cashew nut meal, cocoa by-products, tamarind seed meal, and tapioca. The formulation results indicated that these ingredients have the potential to be combined as components of broiler diets, resulting in a formulated diet containing approximately 15.63% crude protein, 9.19% crude fat, 9.42% crude fiber, and 3,022.88 kcal/kg metabolizable energy. The Precision Nutrition approach provides a framework for adjusting ingredient composition to meet broiler nutrient requirements while considering ingredient inclusion limits and potential antinutritional factors. The resulting formulation still requires verification through laboratory analysis and biological feeding trials before being applied to commercial broiler production.

Abstract

Conceptual understanding is an essential competency that students need to develop in biology learning, particularly when studying complex and abstract topics such as the human locomotor system. This study aimed to analyze the effect of implementing the Discovery Learning model assisted by the BioDigital Human 3D Web on students’ conceptual understanding of the human locomotor system and to examine students’ responses to the use of the learning media at SMA Negeri 2 Maumere. This study employed a quantitative approach using a quasi-experimental method with a Nonequivalent Control Group Design. The population consisted of all Grade XI science students, while the samples were selected using purposive sampling and comprised an experimental class and a control class. Data were collected using a conceptual understanding test administered as a pretest and posttest, along with a student response questionnaire. The data were analyzed using descriptive statistics and an Independent Samples t-test. The results showed a significant difference between the experimental and control classes, as indicated by a significance value of 0.000 (p < 0.05). The experimental class achieved a higher mean posttest score (83.57) than the control class (54.27). Furthermore, students’ responses to the use of the BioDigital Human 3D Web reached 85.46%, indicating a very positive response. Therefore, integrating the Discovery Learning model with the BioDigital Human 3D Web effectively improves students’ conceptual understanding of the human locomotor system and provides a more interactive and meaningful learning experience.

Abstract

21st-century education requires students not only to excel academically but also to master communication, collaboration, and creativity skills. However, interviews with Biology teachers at SMA Negeri 10 Sijunjung revealed that limited learning resources, especially textbooks, caused low student activity and many students’ achievement scores below the minimum criteria. To address this problem, a video-based e-module was developed and validated for practicality, but its effectiveness in learning had not been tested. This study aimed to determine the effectiveness of using a video-based e-module on environmental change material towards cognitive ability (learning outcomes), communication skills, and collaboration skills of Phase E students. This research employed an experimental method with a Randomized Only Control Group Design. The experimental group used Discovery Learning with a video-based e-module, while the control group did not use the video-based e-module. Samples were selected purposively based on similar average exam scores, with class X Phase E2 as the experimental group and X Phase E3 as the control group. The results showed that the average learning outcome was 79.56 (high category), communication skills 87.65 (very high), and collaboration skills 88.04 (very high). Based on data analysis, the use of video-based e-modules was not effective in improving learning outcomes, communication, and collaboration skills.

Abstract

The relationship between flower developmental stages and meiotic progression is fundamental to understanding microsporogenesis and identifying appropriate materials for cytogenetic studies and plant breeding. However, this relationship has not been systematically investigated in Hibiscus schizopetalus. This study examined the association between flower developmental stages, meiotic progression, and chromosomal characteristics in H. schizopetalus. Flower buds were classified into twelve developmental stages based on bud size and external morphology, while cytological observations were performed on stages 1–6 using the aceto-orcein squash method. The relative frequencies of meiotic phases and chromosomal characteristics were subsequently analyzed. The results showed that meiosis I predominated during stages 1–3, whereas meiosis II was more prevalent during stages 4–6. Among all meiotic phases, prophase I occurred most frequently throughout flower development. Uninucleate microspores first appeared at stage 4, while binucleate microspores and pollen grains were observed at stage 6, indicating the progression of microsporogenesis. In addition, the proportion of haploid chromosomes increased in the later developmental stages, corresponding to the completion of chromosome reduction during meiosis. These findings demonstrate that meiotic progression and chromosomal characteristics are closely coordinated with flower development and that flower bud morphology provides a reliable indicator of internal cytological events. The developmental stages identified in this study may serve as a useful reference for selecting suitable materials for cytogenetic analyses, pollen culture, haploid induction, and future breeding of Hibiscus schizopetalus.

Abstract

Domestic wastewater contains organic compounds and nitrogen that can degrade water quality if not properly treated. Microalgae-based treatment offers a dual approach as bioremediation and producer of biomass and lipids with bioenergy potential. This study aims to analyze the effect of photoperiod variation on Chlorella vulgaris biomass production, Chemical Oxygen Demand (COD) and ammonia removal, and lipid content in a Rotary Biological Contactor (RBC) using domestic wastewater. The study was conducted at laboratory scale over eight days with three photoperiod variations, FP1 (15:9), FP2 (12:12), and FP3 (9:15) light: dark hours, under batch and semi-continuous systems. Biomass, lipid content, COD, and ammonia were analyzed gravimetrically and spectrophotometrically. Results showed that the highest biomass was obtained under batch FP1 at 1.53 g with the lowest final COD of 63.49 mg/l, the best ammonia removal under FP2 with a final value of 8.6 mg/l, and the highest lipid content of 40.06% under batch FP2. This study demonstrates that photoperiod optimization in a domestic wastewater-based RBC reactor can simultaneously enhance Chlorella vulgaris productivity in both wastewater treatment and bioenergy production. This research provides a scientific contribution related to the optimal photoperiod configuration in the microalgae-based RBC system, which can be a fundamental reference in the development of sustainable domestic waste processing technology integrated with the provision of bioenergy raw materials.

Abstract

The ban on the use of antibiotic growth promoter as feed additives in livestock has created a need for safer and more accessible antibiotic alternatives. One promising alternative is moringa (Moringa oleifera Lam.). Moringa leaves have the potential to serve as natural antibiotics that support digestive health and the function of visceral organs. This study aimed to analyze the performance of visceral organs following the administration of moringa leaf powder as a feed additive at various concentrations. Thirty female quails were divided into five treatment groups that received 0%, 2.5%, 5%, 7.5%, and 10% moringa leaf powder in their feed, with six replications per group. The quails were culled at 106 days, and their visceral organs including proventriculus, ventriculus, intestines, liver, pancreas, and heart were isolated and weighed. Data were analyzed using ANOVA at a 5% significance level. The results showed that moringa leaf powder supplementation significantly increased pancreatic weight, but did not produce significant differences in the weight of the other visceral organs. It can be concluded that the use of moringa leaf powder as a feed additive has a positive impact on increasing pancreatic weight and helps maintain the weight of the proventriculus, ventriculus, intestines, liver, and heart.
