Abstract

ABSTRAK: Peningkatan kapasitas adsorpsi dan efisiensi penyerapan zeolit alam Ende - NTT sudah dilakukan melalui proses aktivasi kimia. Penelitian ini bertujuan untuk menghasilkan adsorben yang efektif mengurangi kadar logam Pb(II) dalam larutan. Aktivasi zeolit alam tersebut dilakukan dengan memvariasikan konsentrasi asam klorida (HCl) dan dikarakterisasi menggunakan Difraksi Sinar-X (XRD) dan Scanning Electron Microscope (SEM). Sementara proses adsorpsi ion Pb(II) menggunakan zeolit alam teraktivasi tersebut dipelajari pada variasi pH dan waktu kontak. Konsentrasi ion Pb(II) sebelum dan sesudah penyerapan ditentukan dengan instrumen Spektrofotometer Serapan Atom (SSA). Hasil penelitian menunjukkan bahwa konsentrasi optimum HCl untuk proses aktivasi tersebut adalah 3,0 M. Kondisi optimum penyerapan ion logam tersebut terjadi pada pH 4 dan waktu kontak selama 60 menit. Kapasitas adsorpsi dan efisiensi penyerapan maksimum zeolit alam terhadap ion logam Pb(II) berturut-turut sebesar 24.843 mg/g dan 99.37%. Kata kunci: zeolit alam, adsorpsi, aktivasi, logam berat, timbal (II) ABSTRACT: The improvement of adsorption capacity and absorption efficiency of natural zeolite from Ende - NTT has been carried out by chemical process activation using chloric acid (HCl). The purpose of this research was to produce adsorbent that efectively reduce the Pb(II) concentration from solution. The adsorption of the activated natural zeolite on Pb (II) was studied by varying the HCl concentration, pH of the solution, and contact time. The characterization of the activated natural zeolite was conducted with X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). Meanwhile the concentration of ion Pb (II) was measured by Atomic Absorption Spectrophotometer (AAS). The optimum HCl concentration for the activation process was 3.0 M. Moreover, the optimum pH of the solution and contact time were 4 and 60 minutes respectively with the adsorption capacity and the efficiency were 24.843 mg/g and 99.37% respectively.

Abstract

ABSTRAK: Sintesis hidroksiapatit (HAp) dari cangkang telur ayam melalui proses presipitasi basah telah berhasil dilakukan. Tujuan dari penelitian ini adalah untuk mendapatkan kondisi proses yang optimal dan juga untuk mengetahui pengaruh rasio mol Ca/P dan suhu sintesis terhadap karakteristik HAp. Bubuk cangkang telur ayam dikalsinasi untuk mendapatkan CaO yang kemudian direaksikan dengan diammonium hidrogen fosfat dengan menggunakan air sebagai pelarut. Proses presipitasi dilakukan dengan sistem tertutup untuk menghindari terjadinya pelarut hilang saat pemanasan di atas titik didih pelarut. Sampel kemudian diambil untuk dikarakterisasi dengan menggunakan FTIR (Fourier Transform Infrared), XRD (X-Ray Diffraction), dan SEM (Scanning Electron Microscopy). Kelompok fungsional diamati di FTIR HAp yang disintesis adalah fosfat (PO43-), hidroksil (OH-), karbonat (CO32-), dan hidrogen fosfat (HPO42-). Kelompok fungsional ini menunjukkan bahwa HAp telah terbentuk. Data XRD menunjukkan puncak utama untuk HAp yang memperkuat kebenaran karakterisasi FTIR. SEM digunakan untuk mengamati morfologi HAp hasil sintesis yang terdiri dari aglomerat. Kondisi terbaik dalam sintesis ini terjadi pada perbandingan mol Ca/P sebesar 1,60 pada suhu 160oC ABSTRACT: Synthesis of hydroxyapatite (HAp) from eggshell by precipitation method has been successfully done. The aim of this research was to get the optimum process condition and also to investigate the influence of the Ca/P mole ratio andthe synthesis temperature toward HAp characteristic. The powder of eggshell was calcined to get CaO which then was reacted with diammonium hydrogen phosphate by using water as solvent. Precipitation process was done by closed system in order to avoid the solvent be lost while heating up above the solvent’s boiling point. The samples then were characterized by using FTIR (Fourier Transform Infrared), XRD (X-Ray Diffraction), and SEM (Scanning Electron Microscopy). The functional groups were observed in the FTIR of the synthesized HAp are phosphate (PO43-), hydroxyl (OH-), carbonate (CO32-), and hydrogen phosphate (HPO42-). These functional groups indicate that HAp has been formed. XRD data showed the main peaks for HAp that strenghtened the truth of FTIR characterization. SEM was used to observe the morphology of the synthesized HAp that consisted of agglomerates. The best conditions in this synthesis occured at Ca/P mole ratio of 1,60 and the synthesis temperature of 160oC.

Abstract

Waste from the textile industry is considered a potential source of environmental pollution, especially water, because it contains dangerous dyes. In this research, natural zeolite is an effective and efficient alternative to overcome pollution caused by methylene blue and methyl orange dyes. Activation of natural zeolite was carried out with 3 M HCl solution and was characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). Simultaneously, the methylene blue and methyl orange adsorption processes were studied in variations in the weight of the adsorbent, contact time, and pH. The concentration of dyes left in the solution was observed with UV-Vis Spectrophotometer. The results showed that the adsorption capacity of natural zeolite in absorbing methylene blue was 21.189 mg / g and methyl orange was 18.208 mg / g. The optimum conditions of dyes adsorption are achieved with successive adsorbent weights 0.3 g and 0,4 g, following contact times 60 minutes and 90 minutes, and successive pH 6 and 2. The adsorbent weight factor, contact time, and pH affect the adsorption of dyes by natural zeolite from  Ende.

Abstract

This study aimed to implement models and learning tools based on integrated JAS (Natural Surrounding Exploration) approach in the plant taxonomy course particularly plant determination material. This research was conducted by utilizing descriptive method with a qualitative approach. The research was conducted from September to November 2019 in the odd semester at the academic year 2019/2020. The samples were chosen by purposive sampling technique. The samples were 43 students of biology education study program at Universitas Flores who took plant taxonomy course. The research was conducted at Kelimutu National Park. Based on the results, the use of a taxonomic learning model based on natural surrounding exploration was considered quite interesting and encouraged meaningful teaching and learning activities. In addition, based on the results of interviews with biology students, this method provided advantages including (1) being able to increase students' understanding of plant identification, (2) being an attractive medium to trigger learning motivation because it was related to the real context around it, and (3) instilling a caring attitude and love for the natural wealth around and the culture around it.
