Conventional learning models that still dominate the science learning process have a negative impact on learning psychology and student learning outcomes, for example the lecture method. In addition, the integration of local knowledge in learning almost done because the teacher thought local knowledge of science content is not relevant to modern science. This study has the prospect to develop an integrated learning tools nested models based on local wisdom phinisi boat. Products developed focuses on improving communication skills and conceptual knowledge of students. Adapting product development methods development framework Dick and Carey to modify it in 5 stages. Stages of needs analysis, product design, product development, product implementation and evaluation, and the final product. The results of product development tested in a limited class of the class VII SMPN 32 Bulukumba the 15 students who have been selected by purposive sampling. The choice of subjects represented each of 5 students with low, medium, and high abilities. Primary data were obtained from the assessment of the product by 2 experts and through the assessment questionnaire. The feasibility of the product in the category "very high". The syllabus has a validity level of 94.00%, RPP 93.75%, LKPD 96.00%, and assessment instruments 95.00%. Response practitioners and learners in the category ratings "high" and "very high" throughout the assessment indicators. In the implementation phase, learning nested models based on local wisdom boat phinisi provide more space for students to express their knowledge and digging skills
This research is experimental research. The research aims to analyze the absorbance and wavelength values on the certain color spectrum based on the age of noni leaf sample. Variation in absorption and wavelength occurs in the red spectrum ranges between 650 to 700 nm. Maximum absorption occurs in the middle of noni leaf followed by the tip of noni leaf sample but the yellow leaf sample results poor absorption. Chlorophyll a has main leaf pigment the most which occurs in the light reaction of photosynthesis. The maximum absorption which ranges between 3,5 to 4,0 A occurs in the blue spectrum ranges between 400 to 450 nm. Chlorophyll b absorbs photon energy in sun light. A wavelength ranges between 500 to 600 nm occurs in the green spectrum which has low absorption of three samples ranges 0,5 to 1,5 A. The chlorophyll reflects light of the green spectrum; therefore, it causes low absorption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
