Abstract

Rice husk and natural bentonite as well as virgin HDPE were used as rawmaterials to form composite. The aim of study is to know the effect of rice husk and naturalbentonite ratio as filler and the percentage of polyethylene-graft-maleic anhydride(MAPE) as coupling agent on quality of formed composites. The composite formationprocess was done by application of hot press method at 170 oC for 30 minutes. Afterheated and pressed then composites was cooled to room temperature and finallycomposites were tested its mechanical properties of tensile strength and bending strength.The results showed that addition of natural bentonite into matrix of rice husk can increasemechanical properties of composite compared to composites prepared by using only ricehusk and virgin HDPE. The amount of added MAPE affect values of tensile and bendingstrength of composites. The addition of MAPE and natural bentonite on formation ofcomposites caused the increasing adhesion bond between matrix and filler and as a resultalso increased the mechanical properties of composites. On ratio ofrice husk and naturalbentonite of 70:30 with addition of 5 wt% MAPE was obtained the highest tensile strengthvalue of 18.2 MPa and the highest bending strength value of 9.2 MPa.

Abstract

This research aims to improve economic value of cassava peel waste as raw material of bioplastic making, whose existence is still very abundant and has not been benefitted optimally. Bioplastic making is conducted by mixing starch and chitosan with gliserol as plasticizer. Bioplastic making is carried out at gelatinization temperature of 80oC. Chitosan addition is carried out at variatios of 0; 10; 20; 30; and 40 (% w). Research result indicates that mechanical property i.e. optimum value of tensile strength is obtained at value of 38.25 MPa with chitosan addition as much of 30%. The highest elongation percentage is obtained as much of 41.25% with addition of 10% chitosan. Physical property of resulted bioplastic is obtained from the best swelling test at addition of 40% chitosan i.e. 0.38%, and bioplastic density obtained is ranged from 2 – 3.33 g/ml. Analysis of functional group by using FTIR exhibits the existence of ester and carbonyl groups that indicates that resulted bioplastic could be degraded. Whereas biodegradability test on environment exhibits that bioplastic could be completely degraded in soil for 24 days.

Abstract

Cooking oil is a food processing medium that is often used by various levels of society for cooking needs. People’s habit of using cooking oil repeatedly at high temperatures will cause damage to the oil so that it greatly affects the nutrition and quality of processed foods. For this reason, it is very important to make efforts to regenerate cooking oil that has been used repeatedly with a safer process. Corn husks can be used as a bioadsorbent to regenerate used cooking oil. The purpose of this study was to investigate the effect of adding bioadsorbent from corn husks on the acquisition of moisture content, free fatty acids (FFA), and peroxide number. 200 ml of used cooking oil was contacted with corn husk bioadsorbent with the addition of 1, 5, and 10 grams of bioadsorbent and contact times of 30, 60, and 90 minutes. Furthermore, used cooking oil that has been regenerated was analyzed for moisture content, FFA, and peroxide number. The results showed that 10 grams of bioadsorbent with a contact time of 90 minutes had a moisture content of 0.15%, FFA 0.11%, and a peroxide number of 1.15 meq/kg, which met the cooking oil quality standard (SNI 3741-1995).

Abstract

Recently, membrane technology has developed rapidly as a process for water treatment. The membrane process is in demand due to several advantages including being able to work at low temperatures, easier to operate and easy to scale up. Magnesium hydroxide (Mg(OH)2) is an inorganic compound that is inexpensive, non-toxic and hydrophilic, so it has the potential to be used as an additive in membrane fabrication. This study aims to determine the characteristics and performance (permeability and selectivity) of Polyethersulfone (PES) membrane modified with Mg(OH)2, using dimethyl Acetamide (DMAc) as solvent. The membrane was made by blending polymer with phase inversion technique and the characterization carried out included membrane morphological tests, functional group tests, water contact angle tests and evaluating membrane performance by measuring membrane selectivity and permeability. The results showed that the hydroxyl group contained in Mg(OH)2 was able to increase the hydrophilicity which was indicated by a decrease in the water contact angle on the modified membrane to 65o. The Mg(OH)2 additive acts as a pore-forming agent which can be seen in the changes in membrane morphology on the cross-section of the membrane surface. The performance of the membrane resulted in an increase in membrane permeability of 51 L/m2.hour.bar with humid acid rejection of 63%.

Abstract

Clean water is a natural resource which is indispensable, due to the increase of population, water demand is also increasing. so that technology is needed in water treatment to satisfy the needs of clean water. Membrane separation technology is a technology that has grown rapidly in addressing the problems of water treatment. The purpose of this study was to determine the characteristics and performance of Polyethersulfone (PES) membranes modified with magnesium hydroxide or Mg(OH)2 and modification using chitosan. Membrane preparation was carried out by the phase inversion method, using an 18 wt% PES polymer modified with the addition of 0.2 wt% of Mg(OH)2, and modification using 0.2 wt% of chitosan. Furthermore, it was dissolved in N-Methyl pyrrolidone (NMP) as a solvent and the dope solution was stirred for 24 hours until it was homogeneous. Membrane characterization includes functional group analysis and measurement of the membrane water contact angle. Whereas membrane performance testing is done through permeability measurement and membrane rejection using a dead end ultrafiltration module. The results showed that the hydroxyl group (-OH) contained in Mg(OH)2 and chitosan were able to improve the hydrophilicity of the PES membrane. The membrane permeability coefficient modified with Mg(OH)2 gives a value of 8.236 L/m2.h.bar, while modifying the membrane using chitosan produces a value of 6.237 L/m2.h.bar. Both of them experience an increase compared to pure PES membrane without modification that has a permeability value of 4.123 L/m2.h.bar.

Abstract

Artikel ini melaporkan tentang karakteristik dan kinerja dari membran polyvinylidene fluoride (PVDF) yang dimodifikasi dengan memadukan surfaktan nonionik dan aditif zwitterionik melalui metode nonsolvent-induced phased separation (NIPS). Modifikasi ini bertujuan untuk meningkatkan sifat hidrofilisitas dan kinerja membran. Membran PVDF modifikasi dibuat dengan penambahan 5 gram Brij-35 dan variasi Methacryloyloxylethyl phosphorylcholine (MPC) sebanyak 0,5 dan 1 gram sebagai aditif, menggunakan pelarut N, N-dimethylacetamide (DMAc) dan non-pelarut berupa akuades. Pengaruh penambahan aditif ke dalam sistem membran dianalisis dengan mengamati perubahan struktur morfologi membran menggunakan SEM, tingkat hidrofilisitas membran diuji dengan mengukur sudut kontak air pada permukaan membran. Selain itu membran juga diuji kinerja filtrasinya menggunakan modul cross-flow. Filtrasi dilakukan pada tekanan operasi 1 bar. Kemudian untuk pengujian rejeksi, digunakan larutan asam humus sebagai model kontaminannya. Kinerja filtrasi membran menggunakan sampel air murni menghasilkan nilai fluks maksimal pada membran yang dimodifikasi dengan penambahan Brij35-5. Namun, selektivitas yang dihasilkan menurun dari 96% (pure PVDF) menjadi 76%. Di sisi lain, membran yang dimodifikasi dengan penggabungan aditif mampu menghasilkan kinerja yang lebih baik yaitu dengan nilai fluks sebesar 126 L/m2h dan mampu merejeksi asam humus sebesar 90%.

Membrane characterization was carried out by observing membrane morphology using Scanning Electron Microscopy (SEM), membrane surface functional group analysis test using Fourier Tranform Infrared (FTIR), membrane porosity test using the dry-wet weight procedure method, the highest porosity value was found on membrane B2 using a solvent DMSO with 2% silica is 16.88%. Membrane performance was carried out by pure water flux testing, the highest pure water flux value was found in membrane B2 with 2% silica, namely 64.14 L/m2.h. The antifouling test uses flux ratio recovery, the highest antifouling value is found on the A3 membrane with 3% silica, namely 91.3%. As well as rejection of the humic acid solution as a Natural Organic Matter (NOM) sample model using the ultrafiltration (UF) module with a dead end filtration flow system, the highest rejection value was found on the B2 membrane with 2% silica, namely 64.4%.
