Authors: Savitri E N , Parmin  , Dewi N R 
Published: July 2020

Abstract
Science learnings provide opportunities to grasp knowledge by constructing and examining explanations of a particular phenomenon. This information is obtained from a scientific process which gives learning experience to students. Green Learning Method (GeLeM) employs natural phenomena as learning sources; therefore, it is suitably applied in science learnings. Green Learning Method (GeLeM) lets students involve in nature learning directly, identifies as well as offers a solution to surrounded environmental problems. Hence, this method is closely related to environmental care behaviour emerged during learning activities. This research intended to reveal pre-service science teachers’ enhancement of environmental care behaviour through Conservation-based Green Learning Method. Data collection process was carried out in the Department of Integrated Sciences, Faculty of Mathematics and Natural Sciences, Universitas Negeri Semarang on Living Organism Systematics course, odd semester, academic year of 2018/2019. The obtained results showed that ‘GeLeM’-based learnings could enhance the students’ environmental care behaviour. Other than that, the observation results indicated that the students’ environmental care behaviour was seen during nature learnings. Pre-service science teachers must have favourable environmental care behaviour to inherit it to their future students.

Published: July 2020

Abstract
This research is driven from the ineffectiveness of village empowerment in the North Coast of Central Java (Pemalang, Tegal Regency, Tegal City, Pekalongan, and Batang), especially in environmental issues. In fact, the environment is an important part of village development and has the most important contribution to a prosperous independent community according to Law No. 6 of 2014 concerning Villages (Village Law). Environmental development (biotic and abiotic) has a very significant role, and humans as one of the biotic components place a strategic position in the development of the environment in the village. This study aims to produce a synergistic model that combines legal instruments, implementation, and environmental education in rural development. Chamblis and Seidman’s theories (about Law and Society) are used in this study and this study emphasizes that: (1) laws and regulations should be used to achieve social welfare and justice, including in environmental terms, but in fact this is not maximally done, (2) village development as a mandate of the Village Law on the North Coast has not been oriented towards environmental development, so that the use of village funds is ineffective, and (3) the synergy model of village development emphasizes progressive legal principles as one of the tools to encourage law enforcement which is more effective.

Abstract
Flavonoid compound from durian shell biowaste was identified by phytochemical assay and FTIR spectrophotometric methods. Total flavonoid content determined by the aluminum chloride (AlCl3) method using a UV-Vis spectrophotometer. Durian shells, which are a waste that causes the environmental problem, can be used as a source of potentially valuable flavonoid compounds. Flavonoid has antioxidants ability that is beneficial and useful. Durian shell used in this research consists of three types, namely Malika, Malon, and Monti, which are from local Indonesian durian. Based on the result, proximate test analysis showed that three local durian shell samples generally had a water content of 7%, a fat content of 0.9%, the protein content of 4.9%, an ash content of 8.5%, and a 78% carbohydrate content. The results of the analysis of the three durian shell samples did not show significantly different results. Then for the phytochemical assay, three local durian shell samples contained phenols, steroids, and terpenoids, the results of the phytochemical assay showed that there were more phenolic groups than the flavonoid group. The following analysis result is the functional group of three samples using Fourier Transform Infrared (FT-IR) spectrophotometer shows that the three types of durian shell samples have a band that is slightly different from the standard, but the number of waves in this band is similar to the standard quercetin. Then for total flavonoid levels in local durian shell using the aluminum chloride (AlCl3) method, the result is Monti durian shell having higher flavonoid levels, each 0.405 ± 0.002 mg QE/g, compared with each other shell type namely Malika and Malon of 0.321 ± 0.003 mg QE / g and 0.324 ± 0.002 mg QE/g, respectively. Thus in this study shows that Indonesian local durian shell contains significant total flavonoid content without the need for extraction. Samples were only dissolved with ethanol solvent, then a series of tests were carried out, then a series of tests were carried out, ranging from phytochemical assessment, FTIR spectrophotometer, and AlCl3 methods to determine the total flavonoid content through quantitative.
