Abstract

Currently, antibiotics are considered environmental pollutants because of their undesirable effects on human health and the environment, including the waste of antibiotics tetracycline hydrochloride. While on the other hand, bagasse is an agricultural waste that has no economic value. This study aims to study the characteristics of activated charcoal from bagasse and the use of bagasse as chitosan-modified activated charcoal using the column method to determine the variation of adsorbent height, flow rate, and acidity of the solution in the ability of the bagasse adsorbent to adsorb tetracycline hydrochloride. Bagasse goes through a carbonation process using a furnace at a temperature of 350°C until charcoal is formed. The next process is activation using 2 M phosphoric acids and compared based on SNI 06-3730-1995 regarding technically activated charcoal. Determination of functional groups using Fourier Transform Infra-Red, adsorbent morphology using Scanning Electron Microscope, and crystallinity using X-Ray Diffraction. The concentration of tetracycline hydrochloride before and after adsorption was measured using an Ultra Violet-Visible spectrophotometer. The best absorption results in the adsorption process were found at the adsorbent height of 14 cm (99%), the flow rate of 0.5mL/minute (92%), and pH 4 (93%).

Abstract

Masih maraknya penyalahgunaan narkoba di masyarakat yang akan berpengaruh terhadap perkembangan dan kemajuan bangsa Indonesia di masa depan maka perlu adanya pengetahuan dan pemahaman tentang narkoba. Karena ini, diperlukan kegiatan-kegiatan yang mendukung pada peningkatan dan pencegahan penyalahgunaan narkoba. Maka dosen dan mahasiswa Fakultas Farmasi Universitas Bakti Tunas Husada bekerja sama dengan Badan Narkotika Nasional dalam kegiatan pengabdian masyarakat. Peserta pengabdian masyarakat adalah para penggiat anti-narkoba di Kota Tasikmalaya. Metode yang dilakukan adalah penyuluhan dan pembagian kuesioner pengetahuan tentang narkoba. Hasil pengabdian masyarakat dapat berjalan dengan lancar dan adanya pemahaman peserta pengabdian masyarakat tentang narkoba.

Abstract

The large use of amoxicillin allows this antibiotic to enter the environment in large quantities and cause pollution. The adsorption technique can be used as a method to remove amoxicillin contaminants in wastewater by utilizing kaolin as an adsorbent. This study aims to determine the characteristics of kaolin as an adsorbent and determine the ability of kaolin to adsorb amoxicillin. Kaolin was activated with hydrochloric acid and modified using Dimethyl sulfoxide (DMSO) and cetyl trimethylammonium bromide (CTAB). The results showed that the characteristics of DMSO and CTAB-modified kaolin showed a new peak which was an O-H bending vibration in functional group analysis using FTIR. X-ray diffraction results show that the distance between planes in the kaolin structure is larger. Meanwhile, the results of the SEM analysis showed that the surface morphology of kaolin had a higher level of crystallinity than before which proved an increase in the adsorption capacity of kaolin. The adsorption kinetics follows the Santosa kinetic equation model with an adsorption rate of 0.004 min-1 and an equilibrium constant value of 0.007 L.mol-1. The adsorption isotherm test follows the Freundlich isotherm equation model with an adsorption constant value of 561.694 L.mg-1 and an empirical constant value of 0.270. Keywords: Antibiotics, Adsorption, Batch, Isotherms, Kinetics
