Abstract

Environmental characteristics in coastal areas receive less attention from educational aspects, especially schools integrating with science learning. This research aims to develop mangrove ecological value-based teaching materials as a strategy to improve students' science literacy. The research methods used are observation methods and quasi-experiments. Data analysis uses descriptive statistical analysis using, then the normality and homogeneity test is done with SPSS 17.0. Next, to test the hypothesis using ANOVA One Way. The science literacy ability of learners is measured using pre-test and post-test questionnaires. The results showed that mangrove ecological value-based teaching materials are worth using based on expert and teacher validation. The response of learners to the teaching materials developed is very interesting. The homogeneity test showed the significance of students' science literacy abilities obtained Levene test scores > 0.05 which means the data is homogeneous. Based on the hypothesis test H0 was rejected, which means there is a significant increase in student science literacy after using teaching materials based on the ecological value of mangrove ecosystems. The effectiveness of teaching materials is evidenced by the percentage of changes in learners' average pre-test and post-test results. The highest post-test grade post-test score was 80.35%, and the lowest was 79.44%. The conclusion is that mangrove ecological value-based teaching materials are significant to students’ science literacy skills, especially in the coastal areas of East Lombok. Therefore, it is necessary to utilize the location's potential as a source of learning learners to be more attractive.

Abstract

One of the ecosystems found in coastal areas is the mangrove ecosystem. Mangroves have many functions including as a shelter, a place to find food, a breeding ground for aquatic biota. Damage to mangrove areas can cause a decrease in the quality of mangrove ecosystems, especially for the life of mangrove crabs. Mud crab is one of the aquatic biota associated with mangroves and its life is influenced by the presence of mangrove forests. Therefore, the purpose of this study was to determine the diversity of mud crabs that live in mangrove ecosystems and the association of mangrove species with several species of mud crabs in the coastal mangrove ecosystem of Lembar, West Lombok. Mud crab samples were taken using purposive sampling by looking at the density of mangroves in each observation plot. The collected data were analyzed by diversity index, ecological index, association and Pearson's correlation coefficient. Then a simple linear regression analysis was performed with the variable (x) density of mangroves and (y) density of mangrove crabs. The results of this study were found to be 10 species of mud crabs consisting of 2 families of Ovalipidae and 8 families of Portunidae which belong to the moderate diversity index. There were 2 species of mud crabs that were positively associated with 2 species of mangroves out of 10 species of mud crabs found. Linear regression equation y = 0.2482x + 0.0004 with a pearson correlation coefficient (r²) (0.58).

Abstract

Mangroves have a function as shelters, nurturing places, spawning grounds, and foraging places, and can be a habitat for wild animals. Brachyura is one of the mangrove biota associations whose lives are influenced by the existence of mangroves. Therefore, the purpose of this study is to determine the diversity of crabs (Brachyura) and the relationship between mangrove density and crab abundance (Brachyura) in the coastal mangrove area of Gerupuk Beach Central Lombok. The crabs (Brachyura) sampled were Brachyura contained in the observation plot, Brachyura on the surface of the substrate was taken by hand, while those in the hole were taken with the help of a shovel. The data obtained were then analyzed with the Pearson diversity index, association, and correlation coefficient. Furthermore, a simple linear regression analysis was carried out with the independent variable (x) mangrove density and the dependent variable (y) crab abundance (Brachyura). The results of this study obtained 7 species of Brachyura consisting of 6 species of the family Ocypodidae and 1 species of the family Grapsidae. The Brachyura diversity index at the research station was moderate to high with values between 1.7-4.0. Furthermore, there are 3 species of crabs (Brachyura) associated with 2 species of mangroves out of 7 species of Brachyura found. The linear regression equation y= 0.2619x + 0.0206 with a pearson correlation coefficient value (r) of 0.79 shows a strong relationship between the variable independek (x) mangrove density and the dependent variable (y) Brachyura abundance. The conclusion of this study is that Brachyura diversity in the Gerupuk Beach mangrove area is included in the medium category and there is a significant relationship between mangrove density and Brachyura abundance

Abstract

The present work aims to study the effect of pineapple fruit extracts on the quality of Chemical and microbiological - rabbitfish sauce products. Utilizing pineapple extract can speed up the fermentation process because pineapple extract contains bromelain enzymes that will break down rabbitfish’s protein, carbohydrate, and fat molecules into simpler molecules. The research method applied involved experimental laboratory procedures. This study used a completely randomized design. The variables observed were protein, water content, acidity (pH), total microbe, total lactic acid bacteria, Escherichia coli, Staphylococcus, and taste values. The pineapple extracts and fermentation length affected sauce product quality significantly. Pineapple extracts of 15% and 12-day fermentations produced the best sauce quality, consisting of 14.18% protein content, 73.55% moisture content, and a pH of 5.26. Besides, other parameters observed were total microbes 7.8 x 104 CFU/g, total lactic acid bacteria 1, 0 x 102 CFU/g, E. coli, and Staphylococcus sp. (negative), taste value was 3.46, but consumers did not like it so much. However, these results have met the Indonesian National Standards for the product and are safe for human consumption.

Abstract

This study aims to describe aspects of the reproductive biology of a blue swimming crab (Portunus pelagicus) that landed at the southern end of the coast of East Lombok during the period November 2023 to April 2024. The study used a descriptive design with a quantitative approach to measure and analyze data through direct observation. Data included carapace width, body weight, gonad maturity stages, and gonad somatic index (GSI) of P.pelagicus. The results showed that the male P.pelagicus population was more dominant than females every month. P.pelagicus body weight varied, with significant increases in certain months caused by spawning. Analysis of the relationship between carapace width and body weight showed positive allometric growth, with b values of 3.17 for males and 3.10 for females, indicating that body weight gain was faster than carapace width. The maturity stages of the P.pelagicus gonads were mostly at stages I and II, with a few reaching stages III and IV. The average gonad maturity stages increased from 2.42% in November to a peak of 5,83 % in February, then decreased in the following months. The primary spawning time occurs from December to February, characterized by changes in gonad color and a decrease in the body weight of the P. pelagicus after spawning. Hopefully, this study’s results can positively contribute to the sustainable management of crabs (P. pelagicus).
