Abstract

Logam Zn (seng) merupakan salah satu logam berat berbahaya yang dapat mencemari lingkungan. Salah satunya pencemaran pada perairan, pencemaran ini disebabkan dari berbagai pembuangan limbah industri seperti tekstil, kayu, pelapis logam dan lain-lain. Ada berbagai cara yang dapat digunakan untuk menangani pencemaran lingkungan ini, seperti penggunaan karbon aktif, hidroksida pengandapan, selaput pemisahaan dan lain-lain, namun Teknik ini masih meninggalkan masalah seperti penanganan lumpur kimia yang dihasilkan dan biaya yang masih mahal. Adsorpsi dengan biomassa hadir sebagai alternatif karena biaya yang relatif rendah dan kemudahan dalam pengoperasiannya. Biomassa ini bisa didapatkan dari bebagai buah dengan menggunakan kulit buah, seperti kulit jeruk, kulit lengkeng, kakao dan durian. Kulit buah ini mengandung senyawa selulosa dan pektin yang dapat dijadikan sebagai bahan penyerap ion logam berat.

Abstract

In writing scientific work, a work system is needed online (online) so that the search process is fast and accurate. The online data-based writing model with endnote application is an alternative model of scientific writing that can be applied to school teacher teachers and lecturers. The purpose of this study was to develop a model of scientific writing and measure the effectiveness of its application to MGMP Chemistry teachers in Padang Panjang City. The method used is the development of the ADDIE model and the success test with CV (Coefficient of Variations). Implementation is carried out on all Chemistry teacher teachers who are members of the Padangpanjang City Chemical MGMP. Each teacher will receive training and assistance in creating an Online Library as a database. The training continued with the application of the preparation of scientific works based on student learning outcomes data in each school. From the results of the study, it was found that the level of ease in literacy and compilation of scientific work reached 70% SS and 30% S. The level of interest of Master in compiling scientific work with Endnote reached 30%. SS san 70% S. The desire of participants to start compiling scientific work reaches 20% US, 60% S and 20% SS. The training effectiveness test found that the coefficient of variation had decreased from 2.75% to 1.63%, so it could be concluded that the model for the preparation of scientific work was successfully applied to the Teachers of the Padangpanjang Chemical MGMP.

Abstract

This study aims to develop e-module teaching materials based on problem-based learning integrated scientific literacy and demonstration videos on acid and base materials that are useful for assisting the learning process of students. This research belongs to Educational Design Research (EDR) with the Plomp development model. The research tools used are interview forms, validity, and practicality questionnaires. The electronic module is verified by six verifiers, Including three lecturers and chemistry teachers. The data shows that problem-based learning e-module teaching materials and equipped with scientific literacy along with demonstration videos are needed. The data were analyzed using the Content Validity Ratio (CVR), the Aikens'V formula, and the percentage of practicality. Analysis of the validity questionnaire data showed an average CVR score of 1 (for content validity) and Aikens' V average score of 0.88 (for construct validity). Analysis of the practicality questionnaire data showed an average score of 90% and 89% (for small group and field test practicalities). The data analysis shows that the e-module has a high level of validity and practicality. Therefore, it can be concluded that the developed electronic module teaching materials based on problem learning integrated scientific literacy and demonstration videos are valid and practical.
