Abstract

The mangrove forest has unique characteristics, plays a role in ecological and economic functions, and is a natural resource that has not been optimally utilized. This research was conducted in Tungkal 1 Village, Tanjung Jabung Barat Regency, Jambi, to identify the potential utilization of mangrove plants as entrepreneur-based products. The research method involved surveys selected using snowball sampling, interviews with various stakeholders, and data analysis on respondent characteristics, knowledge, understanding, mangrove-based products, community involvement, support, accessibility, and economically valuable strategies for utilizing mangrove plants. The results show that the majority of the community has knowledge about mangrove forests, but their understanding of the potential utilization is still low. Mangrove-based products such as ecotourism, handicrafts, and sustainable fish farming have high economic potential. The level of community involvement in mangrove conservation and support for preservation efforts is high. In conclusion, mangrove management in Tungkal 1 Village can serve as a successful example in supporting sustainable local economic growth while preserving the important

Abstract

Chicken feather waste, after being finely chopped, is converted into feather panels which can be an alternative material in architecture. Chicken slaughter waste produces 4-9% of live weight in the form of feathers, requiring technology to make it a renewable alternative material. This research aims to process chicken feather waste into alternative materials for room dividers and building walls, reducing environmental impacts. Scanning is carried out to analyze the surface characteristics of the panels before they are applied as environmentally friendly materials. Previous research recorded a chicken feather panel density of 0.38-0.4, categorizing it as a soft stiff fiberboard material. Experimental engineering methods and material scanning in the microstructure laboratory using SEM reveal surface topography and material composition. The test results show that chicken feather panels can be recommended as a new alternative material in architecture. This discovery has the potential to use chicken feather waste in a sustainable manner, providing an environmentally friendly alternative and reducing the burden on the environment. The integration of these materials can enrich innovation in sustainable construction.

Abstract

Disasters including earthquakes can traumatize people, especially children. One of the impacts is impaired concentration, making it difficult for children to learn or study. Hopefully, the right learning model can help students continue to participate in learning and heal the trauma. To find out this learning model, it is necessary to carry out a process of characterizing students in post-disaster areas. Based on the results of questionnaires and interviews with teachers and students in post-disaster areas, it is known that some students are still experiencing trauma, as indicated by 51.80% of students still having difficulty concentrating on studying. It is also known that the learning style of most students is auditory because 91.10% of students learn happier when they hear the teacher telling stories. Furthermore, student’s learning styles are visual as shown by 83.90% of students enjoying reading, 80.4% of students enjoying seeing pictures, and 57.10% enjoying seeing animations. Judging from the tendency for collaboration, students prefer to study in groups. Based on these characteristics, students enjoy learning with active, interactive, and fun activities, so the AICEF learning model can be an alternative that can be used as a learning model for elementary school students in post-earthquake areas

Abstract

The paper aims to determine the difference in science learning outcomes of students who apply the demonstration method and the science learning outcomes of students who use conventional learning in class IV elementary school. The type of research that the author uses is experimental research. This research uses a group of research subjects from a certain population, then grouped randomly into two groups or classes, namely the experimental class and the control class. The experimental class was treated using the demonstration method and the control class used the conventional method, then both classes underwent the same post-test. The sampling technique used was non-probability sampling with proportional sampling. The same number of students and class average scores that are close to the same are class VA and class VB. After getting the sample class, the two classes were randomly drawn, then class VA was obtained as the experiment and class VB as the control. The results of this research can be seen from the results of the hypothesis test using the t-test which was carried out so that the value of t_count=0 and t_table= 2.02 was obtained. From the distributed table t, we get ttable = 2.02. So, it can be concluded that t_count > t_tabel, where 0 > 2.02, thus the working hypothesis H_1 is accepted, meaning there are significant differences in learning outcomes in the two samples. This research concluded that the science learning results of class IV students who used the demonstration learning method did not have a significant difference because the two sample classes got the same learning results, due to the limited time of the researcher who delivered the material to the experimental class

Abstract

The natural resources of agricultural products have the potential to be raw material for making biodegradable plastic, one of which is starch from kluwih seeds (Artocarpus camansi). This study examines the potential of kluwih seed starch as a basic material for making biodegradable plastic. This research method is experimental, the raw material for making biodegradable plastic is the kluwih seed starch originating from Aceh Besar Regency, Aceh Province. Other additives used are chitosan as reinforcement and glycerol as plasticizers. The analysis is carried out, namely mechanical properties, morphology, thermal, functional groups, water absorption and degradation analysis. The results of the analysis of this study show that the kluwih seed starch functions as a basic material for making biodegradable plastic. As chitosan concentration increases, the resulting tensile strength increases with results obtained around 119.17-166.67 kgf/mm2, while the percentage of elongation is lower the results obtained are 6.82-11.15%. The morphological analysis shows the biodegrable plastic produced has a compact and homogeneous structure. The thermal analysis shows a good thermal stability to ranging from 180 to 370 oC. The results of the biodegradable plastic FTIR show wave numbers 1662.64–1049 cm-1. Water absorption analysis is obtained around 7.658-12.068%, a decrease in water absorption is influenced by the addition of chitosan concentration. Biodegradable paltic planted in the soil containing EM4 degraded for 3 days.

Abstract

This study examines respondent and university type responses to science process skills instruments integrated with automated feedback on science practicum performance assessments at 2 state college and 2 private college in West Nusa Tenggara Province. A Kruskal-Wallis test was performed utilizing case study and cluster random sampling. Data was collected using online survey, interviews, and direct observations. Three hundred seventy-six university students and teachers from four universities were studied. Since there was no standard instrument, science process skills performance was not assessed. The assessment results show no statistically significant difference (p > 0.05) between state and private college in measuring science process skills integrated with real-time feedback on science practicum. This suggests that neither university has conducted such an assessment. No significant difference in responses between university students and lecturers regarding the measurement of science process skills on performance assessments integrated with real-time feedback in science practicum (p > 0.05), implying that university students and lecturers have the same experience. This study advises developing science process skills measurement on performance assessment for real-time science practicum feedback.

Abstract

One of the significant danger factors for cardiovascular disease and stroke is dyslipidemia. According to long-term prospective epidemiological research, coronary heart disease is less common in those with good lipid profiles who lead better lives. In this study, on a high-fat diet, female wistar rats (Rattus norvegicus) will be tested and analyzed to see if green tea extract (Camellia sinensis) can prevent dyslipidemia when given orally. Compared to a control group that received only distilled water, the trial group that received 5 milliliters of green tea extract (Camellia sinensis) had significantly lower total and LDL cholesterol levels and higher HDL cholesterol levels. This treatment was more effective in lowering cholesterol overall. The components found in green tea (Camellia sinensis), including tannins, steroids, alkaloids, saponins, and flavonoids, can induce this. When certain bioactive substances are off, the body can bring them back into normalcy. These results suggest that white wistar rats (Rattus norvegicus), given a high-fat diet, can benefit from green tea (Camellia sinensis) extract to avoid dyslipidemia. Your lipid profile can be improved by ingesting green tea extract. The primary polyphenol in tea, catechin, is responsible for this transformation. Therefore, the Camellia sinensis plant, from which green tea is made, is a valuable plant that can halt or slow the progression of several ailments, including hypertension, metabolic disorders, and cardiovascular disorders.
