Abstract

This research aims to i) implement the solar cell based power-bank prototype for learning media; ii) describe the feasibility of the solar cell-based power-bank prototype for learning; and iii) describe students' scientific literacy. This research method uses the analysis, design, development, implementation, and evaluation (ADDIE) research and development model. The subjects of this research are class IX students and science teachers at SMPN 4 Central Bengkulu. Data collection techniques include questionnaires, tests, and interviews. The data analysis technique uses N-gain analysis, percentages, and the Aiken's V formula. The research results show that the media developed is valid with an Aiken index value of 0.98 > the minimum standard Aiken' V of 0.92 and can increase students' scientific literacy based on an N-gain of 0.92. 0.71, this can be seen in the dimensions of context and content based on N-gain of 0.73 and 0.69, while the dimensions of attitude, curiosity, respect, and willingness, reflect the respective percentages of 79.62%, 78.86%, 78.89%, 75.60%. Based on the results of the hypothesis test, the sig value is obtained. (2 tailed) 0.000 < 0.05 which means Ha is accepted and Ho is rejected, which means the solar cell-based renewable energy media used in science learning influences the increase in students' scientific literacy.

Abstract

The purpose of this study was to determine the diversity of gastropods on Cukuh Raya Beach, Kaur Regency and to produce a valid classification booklet of living things. Based on the results of sampling at Cukuh Raya Beach, 12 species of gastropods were obtained, namely: M. annulus, T. chrysostomus, T. canaliculatus, R. aspera, N. canrena, C. femorale, V. musica, N. undata, T. radiatus G., R. nilotica, O. sayana R., and O. polpasta D. The research and development design used, namely (R&D) is based on the 4-D model starting from defining (Define), designing (Design), developing (Develop), and disseminating (Disseminate), but only carried out up to the development stage. The booklet developed was made with an attractive cover and Open Sans font that is in accordance with EYD. The booklet contains a front cover, foreword, table of contents, learning objectives, indicators of learning objective achievement, summary of materials, gastropod diversity, evaluation questions, and bibliography. The average results by expert (lecturer) and practitioner (teacher) validation obtained a percentage of the booklet content aspect of 90%, language aspect of 93.8%, and graphic/design aspect of 88.6% with an average of 90.8% in the category of "very feasible". Thus, it can be concluded that the developed product is very feasible to be tested in the learning process.
