Abstract

The textile industry is one sector that generates effluent containing a significant quantity of pollutants, including dyes, and thus has an effect on the environment. Synthetic dyes, which are toxic and difficult to degrade, are utilized extensively in the textile industry. Therefore, a new study utilizes banana stems as a cost-effective biosorbent to remove indigo carmine dye. This research aims to investigate the use of banana stem waste as a bisorobent in batch method to adsorption indigo carmine dye. The optimal concentration and pH values are 2 and 900 mg/L, respectively. The interaction between the indigo carmine dye and the banana stems is suggested by the FTIR analysis.  The solution's indigo carmine dye may be adsorbed by banana stem.

Abstract

Nanotechnology is a fast expanding field with several applications in science, engineering, healthcare, pharmaceutical, and other areas. Nanoparticles (NP) are frequently produced through a variety of physical and chemical methods. Recently, green synthesis technologies that are more simple, sustainable, and cost-effective have been developed. The environmentally friendly/sustainable synthesis of titanium dioxide nanoparticles (TiO2 NPs) has been in great demand in the previous quarter. Bioactive components found in organisms, such as plants, facilitate the processes of bio-reduction and restriction. This review described green synthesis of TiO2 NPs, the photocatalytical uses, and managing the larvicidal activity of disease-spreading mosquitoes. Various natural reducing agents including proteins, enzymes, phytochemicals, and others, are involved in the synthesis of TiO2 NPs. Current research findings and future concerns in a viable platform based on biologically meditated TiO2 nanostructures for industrial applications.

Abstract

Phenol is one of the organic compounds that are toxic and carcinogenic. In this study ZnO/zeolite was used to degrade phenol by photolysis and its application to rubber waste. Phenol analysis was performed using a UV-Vis spectrophotometer and Fourier Transform Infrared (FTIR), while the ZnO/zeolite characterization used FTIR and X-Ray Diffraction (XRD). The results showed that the percentage of phenol degradation without a catalyst was 15.79% with UV irradiation for 75 minutes and increased to 79.63% with the addition of 0.4 g ZnO/zeolite. Phenol degradation in rubber wastewater samples using ZnO/zeolite obtained a degradation percentage of 58.28%. Phenol analysis before and after degradation showed a shift in wave number which indicated the occurrence of degradation. Characterization of ZnO/zeolite before and after degradation using FTIR and XRD showed that there was no change in the structure of ZnO/zeolite

Abstract

Artikel ulasan ini memaparkan perkembangan terkini pada aplikasi metode adsorpsi dalam menghilangkan zat warna dalam air limbah. Artikel ulasan ini memberikan informasi mengenai aplikasi zat warna serta penanganan limbah dari aktivitas industri yang menggunakan zat warna dan informasi mengenai penggunaan limbah padat pertanian dan perikanan sebagai penyerap berbagai jenis zat warna. Pengolahan limbah yang mengandung zat warna melalui adsorpsi menggunakan adsorben alternatif berbiaya rendah merupakan bidang yang saat ini berkembang dan banyak diminati karena memiliki manfaat yaitu untuk pengelolaan limbah cair dan pemanfaatan limbah padat organik.
Koagulasi Ramah Lingkungan Dengan Kapur Sirih (Ca(Oh)₂) untuk Penghilangan Mikroplastik Pada Ikan Bilih (Mystacoleucus Padangensis) Dari Danau Singkarak, Wilayah Tanah Datar, Sumatera Barat, Indonesia Putra, Zaki Aiwa; Deswati, Deswati; Zein, Rahmiana

Abstract

Kapur sirih (Ca(OH)₂) diteliti sebagai koagulan anorganik yang tersedia secara lokal dan ramah lingkungan untuk mengurangi kontaminasi mikroplastik pada ikan bilih (Mystacoleucus padangensis) dari Danau Singkarak, Tanah Datar, Sumatera Barat, Indonesia. Studi ini mengevaluasi efisiensi koagulasi, kondisi operasi optimal, dan mekanisme yang mendasari. Penghilangan optimal dicapai pada konsentrasi koagulan 5%, waktu kontak 60 menit, dan kecepatan pengadukan 300 rpm. Penambahan 5% NaCl secara signifikan meningkatkan kemampuan pengurangan mikroplastik, mencapai efisiensi hingga 70,73%. Analisis morfologis dengan Scanning Electron Microscopy (SEM) menunjukkan pembentukan gumpalan besar, mengindikasikan interaksi fisik antara mikroplastik dan endapan kalsium hidroksida. Penurunan nilai zeta potensial setelah koagulasi menunjukkan netralisasi muatan yang efektif dan destabilisasi koloid. Hasil ini menyoroti kapur sirih sebagai koagulan yang menjanjikan, berbiaya rendah, dan berkelanjutan untuk mengurangi polusi mikroplastik di lingkungan air tawar, terutama di daerah danau.
