Pernelitian dengan sistim batch telah dilakukan untuk mempelajari pengaruh perlakuan pH larutan dan dosis adsorben yang dibuat dari limbah lumpur aktif industri crumb rubber (LLA-ICR) terhadap kapasitas adsorpsi dan efisiensi penyisihan ion Cd(II) dan Zn(II) dalam larutan. Pengamatan meliputi variasi pH larutan pada range 1-7 dan dosis adsorben LLA-ICR 0,1 g - 1,0 g. Karakterisasi adsorben sebelum dan sesudah proses adsorpsi dilakukan dengan menggunakan FTIR, XRF dan SEM–EDX. Hasil penelitian menunjukkan bahwa perlakuan pH larutan dan dosis adsorben berpengaruh pada kapasitas adsorpsi dan efisiensi penyisihan ion Cd(II), dan Zn(II). pH optimum didapatkan pada pH 5. Semakin rendah dosis adsorben, maka semakin tinggi kapasitas adsorpsi namun semakin rendah efisiensi penyisihan ion Cd(II) dan Zn(II). Dosis adsorben optimum didapatkan pada 0,1g, dengan kapasitas adsorpsi dan efisiensi penyisihan ion Cd(II) > Zn(II). Kapasitas adsorpsi maksimum untuk ion Cd(II) dan Zn(II) berturut-turut 29,8 mg/g dan 10,3 mg/g. Efisiensi penyisihan maksimum intuk ion Cd(II) dan ion Zn(II) adalah 95,4% dan 87,9%. AbstractA batch system has been carried out to study the treatment effect of pH solution and adsorbent dosage derived from crumb rubber (LLA-ICR) industrial activated sludge on the adsorption capacity and removal efficiency of Cd(II) and Zn(II) ions in aqueous solution. Observations included variations in the the solution pH in the range 1-7 and the LLA-ICR adsorbent dosage of 0.1 g - 1.0 g. Characterization of the adsorbent before and after the adsorption process was carried out using FTIR, XRF, and SEM-EDX. The results showed that the treatment of the pH solution and the adsorbent dose affected the adsorption capacity and removal efficiency of Cd(II) and Zn(II) ions. The optimum pH was obtained at pH 5. The lower the adsorbent dose the higher the adsorption capacity, however the lower the efficiency removal of Cd(II) and Zn(II) ions. The optimum adsorbent dosage was obtained at 0.1 g with adsorption capacity and removal efficiency of Cd(II) > Zn(II) ions. The maximum adsorption capacity for Cd(II) and Zn(II) ions were 29.8 mg/g and 10.3 mg/g respectively. The maximum removal efficiency forCd (II) and Zn(II) ions were 95.4% and 87.9%.

Publisher : Institution for Industrial Research and Standardization of Industry - Padang

Tannin made from gambier extract contains hydroxyl groups and so can be modified to synthesize polymers. Gambier extract has a high tannin content that contains polyflavonoids with other additives. This allows it to be modified by polycondensation to make a polymer foam which can be used as an insulator for heat and sound, an absorber of heavy metal pollutants and for protective packaging. This study investigates the utilization of gambier in the manufacture of foam and determines the physical properties of the foam produced. The study was conducted using ethanol to produce the gambier extract from leaves of the plant which was used in the proportions of 14%, 24%, and 34% by weight to make different foam samples. Foam produced from 24% gambier extract had optimum qualities with a density value of 0.34 g/cm3, pH 6.83, compressive strength of 0.14 kg/cm2, thermal conductivity of 5.52 W/moC, and was semi-flexible foam.

Publisher : Institution for Industrial Research and Standardization of Industry - Padang

Singkong karet (Manihot glaziovii Muell) adalah salah satu sumber bahan baku bioetanol yang mempunyai kandungan pati yang cukup tinggi (98,5%). Penelitian ini bertujuan mempelajari kinerja katalis H2SO4, HCl, dan zeolit pada proses hidrolisis pati umbi singkong karet untuk menghasilkan glukosa. Proses hidrolisis untuk katalis homogen dilakukan pada temperatur 120oC dan volume asam 250 ml, sedangkan untuk katalis heterogen dengan rasio massa pati dan aquades (1:25), waktu 60 menit, dan temperatur 120oC. Perolehan glukosa untuk katalis homogen diamati melalui variasi konsentrasi HCl dan H2SO4 masing-masing (0,1; 0,15; 0,2; 0,25; dan 0,3 N) dan waktu hidrolisis (45; 60; dan 75 menit). Untuk katalis heterogen, perolehan glukosa diamati melalui variasi massa zeolit (1; 3; dan 6 g), jenis asam pengaktif HCl dan H2SO4 dengan konsentrasi0,15 N, dengan metode perendaman dan pemanasan pada temperature 50oC. Hasil penelitian memperlihatkan konsentrasi dan waktu hidrolisis pati singkong karet berpengaruh terhadap perolehan glukosa pada penggunaan jenis katalis homogen (H2SO4 dan HCl). Glukosa tertinggi (27,25%) diperoleh pada katalis homogen dengan konsentrasi H2SO4 0,15 N dan waktu 60 menit. Zeolit yang diaktivasi dengan HCl dengan metode perendaman menghasilkan kadar glukosa lebih tinggi (14,13%) daripada zeolit yang diaktifkan dengan H2SO4 (12,58%).AbstractRubber cassava (Manihot glaziovii Muell) is one source of bioethanol raw material which has high starch content (98.5%). The manufacture of bioethanol is carried out through the process of hydrolysis and fermentation. This research was aimed to study the performance of the homogeneous and heterogeneous catalysts in the hydrolysis process of starch from rubber cassava tubers to produce glucose. The hydrolysis process for homogeneous catalyst was carried out at a temperature 120oC and 250 ml acid volume, while for heterogeneous catalyst was the ratio of starch mass and distilled water (1:25), 60 minutes time, and 120oC temperature. The glucose obtained for heterogeneous catalyst was observed through variations of HCl and H2SO4 concentrations (0.1; 0.15; 0.2; 0.25; and 0.3 N) and hydrolysis time (45; 60; and 75 minutes). For heterogeneous catalyst, the glucose obtained was observed through zeolite mass variations (1; 3; and 6 g), type of activating acid HCl and H2SO4 with 0.15 N concentration by immersion and heating method at 50oC. The results showed that the concentration and hydrolysis time of rubber cassava starch affected the glucose obtained in the use of homogeneous catalyst types (H2SO4 and HCl). The highest glucose was obtained at 0.15 N acid concentrations and 60 minutes time. Zeolite which was activated with HCl with soaking method resulted in higher glucose levels (14.13%) than activated with H2SO4 (12.58%).
