Abstract

This research is development research that aims to produce Student Worksheets (LKS) with a valid and practical contextual approach so that it is suitable for use in the learning process on arithmetic and geometric sequences. The development design used in this study is the ADDIE development model, which consists of five stages, namely 1) the analysis stage, 2) the planning stage, 3) the development stage, 4) the implementation stage, and 5) the evaluation stage. Based on the data analysis results, the following results were obtained (1) the level of validity got a score of 3.3 with very valid validity criteria, (2) the level of practicality got a score of 3.9, with efficient criteria of practicality. Therefore, it can be concluded that the developed worksheets meet the good criteria so that they are suitable to be used as one of the teaching materials that can be used in Arithmetic and Geometry Sequences.

Abstract

Traditional mining methods, such as amalgamation and cyanidation in illegal mining, can generate dangerous metal waste discharge, some of them are Zn(AsO4)2.8H2O and Zn(CN)2. Mining waste containing Zn2+, if discarded in water, will harm sea ecosystem, such as fishes, planktons, and others, because Zn(II) cannot be biodegraded in the body which induce toxic effects. Therefore, it takes a sensitive method and has a high selectivity for the separation of metal ions prior to discharge into the environment. The purpose of this study is to determine the optimum conditions of immobilization FHA-bentonite in the metal ions Zn (II) and determine% recovery of metal ions Zn(II) in the desorption process by the method of immobilization chelating agent by fatty acid hidroksamik of synthesis kernel oil seeds ketapan that has a high chelate. The method is combined with bentonite in order to maximize the separation and concentration of ions Zn (II). From the research results, optimum pH of 5, optimum contact time of 5 hours, and optimum concentration of 120 ppm was obtained, with FHA-bentonite adsorption capacity as much as 10,595 mg/g and recovery result of 103,18 ppm from 103,38 ppm or approximately 99,806%. Therefore it could be concluded that hydroxamic fatty acid can be used as chelating agent to separate and concentrate Zn(II) ion immobilized into bentonite resin.

Abstract

This research aims to see the level of participation of the Ekas Buana Village community in managing mangrove forests. This research is qualitative descriptive research. Data collection was carried out by giving questionnaires to respondents and interviews with resource persons as well as direct observation. Determining respondents used a purposive sampling approach by paying attention to the respondent's background. The results of this research show that the level of participation of the Ekas Buana Village community in managing mangrove forests varies, depending on the type of participation carried out. Participation in the form of providing input and ideas in managing mangrove forests is relatively high, while participation in the form of money or goods is very small or low.

Abstract

Natural Science learning in junior high schools should strive for learning through concrete activities; by presenting natural phenomena in every learning this can increase students' interest in learning. However, in reality, science learning, especially at MTs NW Aik Anyar, still uses conventional learning, making students less motivated in participating in learning. This study aims to determine the increase in science learning motivation of grade VIII students at MTs NW Aik Anyar after the implementation of the Problem Based Learning (PBL) model. This type of research is class action research (PTK) with the subject of the study being grade VIII students with a total of 25 students. Data on students' motivation to learn science was collected by questionnaire. Once the data were obtained, they were analyzed using descriptive statistical analysis. Based on the results of data analysis, in the first cycle, the average motivation to learn science of grade VIII MTs NW Aik Anyar students after participating in learning by applying the Problem Based Learning model was 103.81 and was in the high category. The classical completion percentage is 75%. In the second cycle, the average motivation of students to learn science increased to 119.51 and was in the very high category. The classical completion percentage is 95%. Based on these results, it can be concluded that the Problem Based Learning l model is effectively able to increase students' motivation to learn science.
