Periodic adalah jurnal nasional yang berisi artikel-artikel bidang ilmu kimia, seperti bidang Kimia Analitik, Kimia Fisika, Kimia Anorganik, Kimia Organik dan Biokimia. Jurnal ini mempublikasikan hasil penelitian original, komunikasi singkat, dan artikel review. Artikel yang telah diterbitkan dalam jurnal ini berarti bahwa kegiatan penelitian yang diterbitkan adalah belum, dan tidak akan diterbitkan di tempat lain. Periodic (e-ISSN 2339-1197) diterbitkan oleh Jurusan Kimia dan mulai tahun 2022 disebut Departemen Kimia, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Padang, Indonesia. Periodic terbit berdasarkan berdasarkan surat edaran Direktorat Jenderal Pendidikan Tinggi No. 152/E/T/2012 tentang publikasi karya tulis ilmiah dan terbit sejak Oktober 2012.

Abstract

Research Optimizing the absorption of rhodamine b dye has been carried out using the batch method with biosorbent from matoa skin. This study aims to determine the optimum conditions of each parameter used and determine the value of the absorption capacity of matoa skin against Rhodamine B. Variations in particle size used for biosorption of rhodamine b were 106 µm, 150 µm, 250 µm, and 425 µm, while variations in contact time ranged from 30 minutes to 180 minutes with an interval of 30 minutes. The result of measuring the maximum wavelength of rhodamine b dye using a UV-Vis spectrophotometer is 554 nm with an absorbance value of 0.245. For variations in particle size, the optimum adsorption capacity was 71.08 mg/g at 106 µm, while for variations in contact time, the optimum adsorption capacity was 72.85 mg/g at 150 minutes. In this study, matoa peel has the potential to be used as an alternative biosorbent in the absorption of rhodamine b.
