Abstract

Organic wastes of tilapia offal, coconut pulp, and plantain are rarely optimally utilized, but they can be degraded by BSF larvae into nutritious biomass. This study aims to analyze the combination of organic waste macronutrient feed on bioconversion, survival, growth (weight, length, and thickness), and nutritional value (protein, fat, and carbohydrates) of BSF prepupae, using the Completely Randomized Design (CRD) method, 4 treatments P1 (50% tilapia offal: 25% plantain: 25% coconut pulp), P2 (25% tilapia offal: 50% plantain: 25% coconut pulp), P3 (25% tilapia offal: 25% plantain: 50% coconut pulp), P4 (33.3% tilapia offal: 33.3% plantain: 33.3% coconut pulp) and 3 repetitions. All treatments resulted in optimal survival (100%, survival). P4 produced an ECD value of 0.034% and WRI of 0.032% indicating the best efficiency and waste reduction. P1 was the best variation for weight at 5.69 g, length 19.7 mm, and thickness 5.8 mm. The Post Hoc Tuckey test showed no significant difference between treatments in weight and thickness parameters, but not in length parameters (<0.05). The protein content of P1 43.75%, fat P2 29.764%, and carbohydrate P2 1.374% were close to SNI 7994:2014 (meat bone meal, quality II). It was concluded that macronutrient feed waste affects bioconversion, survival, growth and nutritional value of BSF.

Abstract

Low levels of disaster literacy and critical thinking among students highlight the need for innovative and contextualized learning media in science education. This research develops and evaluates the effectiveness of a flood disaster mitigation science E-comic to enhance students’ critical thinking and disaster preparedness. The study employed a Research and Development (R&D) approach using the 4D model (Define, Design, Develop, and Disseminate). Validation results indicated that the E-comic is feasible as a learning medium, with CVI values of 0.89 (media) and 1.00 (content). The use of the E-comic effectively improved students’ critical thinking skills and disaster preparedness, as evidenced by high N-Gain scores and significant statistical results. The improvement was consistently observed across all disaster preparedness indicators, including knowledge, attitudes, and response planning. The study concludes that the flood disaster mitigation E-comic is both effective and feasible as a contextual science learning medium. The integration of flood-related physical science concepts demonstrates how contextualized media can strengthen scientific literacy in disaster education.

Abstract

AbstractThe primary objective of this paper is to address the mitigation of disasters resulting from climate change and global warming. Such disasters are the result of increased greenhouse gas emissions, primarily caused by human activities like deforestation and the use of fossil fuels. To analyze the concept of hydrocarbon combustion from basic competencies (KD) 3.3 and 4.3 of chemistry class XI, we employed a qualitative descriptive method supported by a literature review. The paper investigates the relationship between climate change, the greenhouse effect, the carbon cycle, and their effects on the environment and health. Furthermore, it proposes a learning design that combines the Research-Based Learning (RBL) model with the STEAM approach to enhance students' comprehension of climate change, the consequences of hydrocarbon combustion, and emergency response measures. One of the highlighted learning strategies is the creation of an interactive and engaging mini park mockup to facilitate student understanding. The use of technology, specifically machine learning, is recommended for decision making in global warming disaster mitigation. This paper stresses the significance of integrating chemistry learning for knowledge and skills development in KD 3.3 and 4.3, and for understanding global warming and disaster mitigation efforts. The goal is to provide students with science literacy skills as well as the ability to identify concrete actions in reducing the negative impacts of climate change.

Abstract

All kinds of plants that are found in nature and have medicinal properties are considered medicinal plants. Utilization of medicinal plants can be used directly and mixed. Battra is a person who has knowledge of traditional medicine and is capable of concocting medicinal plants. North Bengkulu is one of the districts that still use conventional medical care. Utilizing medicinal plants that are proven to be able to treat those derived from natural ingredients can be healthful because of very few side effects compared to drugs that contain chemicals. The goal of the study was to catalog the various medicinal herbs used by Battra North Bengkulu. This study used 10 respondents' interviews as its approach. Battra uses 64 species from 37 families of medicinal plants as traditional medicinal ingredients. The most common type of family is Fabaceae. The habitus group that is widely used is 45% trees. Types of diseases that are commonly treated traditionally using these plants include fever, toothache, itching, cramps, internal heat, scales, stomach pain, malaria, long-term fever, colds (cholera), ulcers, lungs, kidney stones, jaundice, high blood pressure, appendicitis, fussy children, eye disease, intestinal worms, kesapo, sprains, tumors and gout. In the processing of medicinal plants by Battra in North Bengkulu, 11 processes the highest drug processing method was by boiling as much as 37%.
