Abstract

This research aims to identify abundance, species diversity, dominance, and evenness and to determine the type of decapod habitat on the coast of Bengkulu City. The method used is the survey method. The sampling location was divided into three stations: Pasir Putih Beach, Panjang Beach, and Kualo Beach. The sampling technique used transects, at each station, an area of 300 m was taken. Decapod diversity was analyzed using the Shannon-Wiener formula, the dominance index (C) was analyzed using Simpson's dominance index, and the evenness index was calculated using Pielou. The results of the research show that on the coast of Bengkulu City, decapod species consisting of six families were found. The diversity index shows that at stations I (0.864/low), II (1.00/medium), and III (0.372/low). Dominance index at stations I (0.046/low), II (0.113/low), and III (0.003/low). Evenness index at stations I (0.415/height), II (0.466/height), and station III (0.92/height). The most common decapods found are the family Hippidae and the species Emerita emeritus, with a total of 18 individuals. The decapod habitat type on Bengkulu City Beach is a sandy beach type. Environmental parameters (DO, water pH, air humidity, light intensity, salinity, and temperature) are in conditions suitable for decapod life.

This research used One Group Pretest-Posttest Design. The population in this study were students of class IX SMP Negeri 7 Bengkulu City with a sample of class IX C totalling 31 students. Determination of the sample using Purposive Sampling technique. The research instrument was a test sheet in the form of multiple choice questions. The test results of student learning improvement  score 0.68 so that it is included in the medium category. The results of this study concluded that there was an effect of ethnoscience in the process of making tamarind bamboo shoots on biotechnology material to improve student learning outcomes and student learning outcomes increased with a moderate category.   Keywords: Ethnoscience, Bamboo Shoots, Biotechnology, Learning Outcomes

Abstract

Background: A BSF maggot (Hermetia illucens) is an organism that can live in waste media because maggots eat and decompose organic materials or waste for their growth. One innovative way to break down several types of organic waste, including vegetable waste, is to use maggots. This research aimed to analyze the effect of vegetable waste feed on maggots’ mass, length, thickness, and protein content. Methods: This research experimented with a completely randomized design (CRD) with five treatments, three repetitions of each treatment with various feed varieties. Analysis of maggot protein levels using the Automatic Kjeldahl method. The parameters measured were the maggot’s mass, length, thickness, and protein content. The variable in this research is the experimental variable for maggot samples with variations in the types of cabbage and mustard greens waste food. The number of samples used was 30 samples for each treatment. The data were analyzed using ANOVA, and a further BNT test was carried out to determine the natural effect of each treatment. Results: The results of the BNT and protein content test show that vegetable waste food significantly impacts the mass, length, thickness, and protein content of maggots. Conclusion: Feeding vegetable waste affects maggots’ mass, length, thickness, and protein content.
