This paper demonstrates the preparation of polyethersulfone (PES) ultrafiltration (UF) membranes via wet phase inversion method using either poly(ethylene oxide)-b-poly(propylene oxide)-b- poly(ethylene oxide) (Pluronic®, Plu) or polyethylene glycol (PEG) as hydrophilic modifier. Their effects on membrane structure as well as the resulting membrane performance and their stability in membrane polymer matrix were systematically investigated. The investigated membrane characteristics include surface hydrophilicity (by contact angle), surface chemistry (by FTIR spectroscopy) and water flux measurement. Visualization of membrane surface and cross section morphology was also done by scanning electron microscopy. The membrane performance was examined by investigation of adsorptive fouling and ultrafiltration using solution of bovine serum albumin as the model system. The stability of additive was examined by incubating the membrane in water (40oC) for up to 10 days. The results show that modification effects on membrane characteristic and low fouling behavior were clearly observed. Further, amphiphilic Pluronic generally showed better performance than PEG.

Membran ultrafiltrasi (UF) telah terbukti sebagai proses yang menjanjikan untuk aplikasi di bidang pemprosesan bahan pangan. Namun, peristiwa fouling dapat menurunkan kinerja membran secara signifikan. Meskipun banyak metode pengendalian fouling telah diusulkan, dalam banyak kasus kinerja proses sangat dipengaruhi oleh membran sebagai jantung dari proses. Dalam makalah ini pengendalian fouling dilakukan dengan memodifikasi permukaan membran dengan teknik kopolimerisasi foto-grafting. Acrylic acid (AA), acrylamido methylpropane sulfonic acid (AMPS), poly(ethylene glycol) methacrylate (PEGMA), dan N,N-dimethyl-N-(2-methacryloyloxyethyl-N-(3sulfopropyl)ammonium betaine sebagai senyawa zwitterion (ZI) digunakan sebagai monomer fungsional. Pengaruh waktu iradiasi terhadap efektifitas modifikasi telah diamati. Kinerja membran hasil modifikasi kemudian diuji dengan menggunakan berbagai model larutan foulant yang meliputi larutan protein, larutan polisakarida dan larutan polifenol. Hasil penelitian menunjukkan bahwa sifat non fouling membran sangat jelas dapat ditingkatkan baik dengan PEGMA maupun dengan ZI. Secara umum, modifikasi menggunakan PEGMA menunjukkan kinerja yang lebih baik. Larutan polifenol menunjukkan karakter foulant yang paling kuat diantara model foulant.

CHARACTERIZATION OF ALGINATE AND CHITOSAN COMPOSITE FILM. Due to the specific characteristics of (thin) films, the use of polymer films in various aplications has singnificantly increased. Alginate and chitosan are natural polymers, which have potential as a raw material for the manufacture of composite films. This paper presents the preparation and characterization of alginate, chitosan and chitosan-alginate composite films. The film characterization included permeability test, degree of swelling, mechanical property, morphology (by SEM), and surface chemistry (by FTIR). The results showed that alginate films have a higher permeability and degree of swelling (DS) than chitosan films. Both permeability and DS decreased with increasing concentration for both alginate and chitosan films. DS experiments showed that the films have the highest DS in water followed by ethanol 95% and ethanol >99.9%, respectively. The mechanical strength of chitosan films was larger than alginate films. Alginate-chitosan composite films prepared by layer by layer method showed better characteristics than the composite films prepared by blending of alginate and chitosan solutions. Meningkatnya aplikasi film polimer di berbagai industri tidak terlepas dari keunggulan yang dimiliki. Alginat dan kitosan merupakan polimer alam yang mempunyai potensi sebagai bahan dasar pembuatan film komposit. Pada penelitian ini dilakukan pembuatan dan karakterisasi film komposit berbasis alginat dan kitosan. Karakterisasi film yang dilakukan meliputi uji: permeabilitas, derajat swelling, mekanik, morfologi (dengan SEM), dan struktur kimia permukaan (dengan FTIR). Hasil penelitian menunjukkan bahwa film alginat mempunyai nilai permeabilitas maupun derajat swelling yang lebih tinggi dibanding dengan film kitosan. Baik pada kitosan maupun alginat memberikan fenomena bahwa semakin besar konsentrasi larutan maka semakin kecil nilai permeabilitas maupun derajat swelling, dengan derajat swelling terhadap air adalah yang paling besar kemudian diikuti oleh ethanol teknis (± 95%) dan yang terkecil adalah ethanol PA (> 99,9%). Kekuatan mekanik film kitosan lebih besar dibanding dengan film alginat. Film komposit alginat-kitosan yang dibuat dengan metode layer by layer memberikan karakteristik yang lebih baik dibanding dengan film komposit yang dibuat dengan pencampuran larutan alginat dan larutan kitosan.

Electroplating industry is characterized in the metal plating process. This process occurs in the electroplating bath that contains a chemical solution. Before the coating process, the metal material to be coated should be washed first to remove the impurity attached. The metal materials that have been completely coated are then took from the bath and rinsed with water to clean the chemical solution attached at those materials. UD Citra Utama obtaines the water used for cleaning from the well in industry area around the company. Unfortunatley, the water well used is characterized by its relatively high salt content and turbid. Initial water analysis showed that those parameters are beyond the standard of water quality used for cleaning in electroplating industry. The use of this water has negative impact such as decreasing thw water quality, slows down the speed of coating process and eventually decreases the capacity and company income. To solve this problem, we have developed water treatment unit that treats the well water into pure water. The unit contains reverse osmosis (RO) membrane, pump, catridge prefilter and media filter. In addition, the unit is equipped with the accessories such as pressure gauge, flow meter and feed/product tank. The results of evaluation showed that water treatment unit can increase the product capacity 30% from 30 m2 to 39 m2 that correspond to income from Rp. 2000000,- to Rp 2600000,-. In addition, this unit can decrease the company omset from 5% to 0.5%. The water produced from this unit could meet the government role (Peraturan Menteri Kesehatan RI Nomor : 416/MENKES/IX/1990).

Fouling is a serious problem that can reduce the performance of the membrane. Therefore the provision of a membrane with low fouling (non-fouling) is an important thing to do. Non-fouling membrane preparation can be done in two ways, namely modification of the membrane surface after it is created (post-modification) and with mixing (blending) during the manufacturing process. However, the surface modification requires an additional step, while the blending method, produced modification is less stable because there is only mixed without a chemical bond. This paper presents the process of Ultrafiltration membrane (UF) of polyether sulfone (PES) by mixing polyethylene glycol (PEG) as an additive and exposed to ultraviolet (UV) that will form a non-fouling membranes are stable. In general, the experiment was conducted on the preparation of the solution casting, followed by irradiation with UV light before it immersed in water for one day and dried. The research was carried out by varying the concentration of PEG, photo-initiator benzophenon, type of UV rays, and long irradiation. Characterization of membrane permeability measurements made with pure water, the appearance of the membrane surface with a scanning electron microscope (SEM) and determine the functional groups on the membrane by FTIR. The results showed that irradiation with UV light and the PEG has a significant influence on the characteristics and performance of the membrane.

Since the formation of the Kyoto's Protocol and is based on reports of the Intergovernmental Panel on Climate Change (IPCC) about the capture and storage of carbon dioxide gas in order to reduce the rate of climate change, there is a continual effort that oriented to the handling of CO2 emissions into the atmosphere, Although Indonesia has never been obligated to reduce its emissions, but this policy will have a big impact on Indonesia, especially in the energy sector. Until now, oil is still the main source of energy in fulfilling energy needs within the country. The role of a very large petroleum will continue, while the dwindling petroleum reserves.Recognizing the dependence on fossil fuels, there should be an effort to press the growth of the use of fuel oil . Nowadays, it has developed an alternative energy known as the Salinity Gradient Energy (SGE). Sanility Gradient Energy has great potential for use as an alternative energy especially in Indonesia, which is the state waters. This research is aimed for study the effect of the concentration of concentrated NaCl solution, dilute NaCl solution flow rate, feed of seawater synthesis and real sea water in generated of power density. This research started inmaking a concentrated NaCl solution with various concentrations of as much as 2 l and a dilute NaCl solution with a concentration of 1 g/l as much as 2 l. Continued with the second turning on the pump diaphragm for both types of feed solution flow into the channels contained in a series of tools. After a few moments appliance operates, the change of output voltage (V) and electric current (A) can be measured using a multitester, this measurement conducted every 20 seconds interval. and then repeat the same steps for each of the variables that have been defined.From this research was found that increase in feed flow rate, then the resulting power density is greater, because of the increased flow rate causes the rate of movement of ions to the electrode increases. on increasing of the concentrated NaCl solution, the resulting power density is greater, because of the increased concentration difference causes an increase in the chemical potential. And for sample nearly the same concentration (30 g/l), the resulting power density of sea water is greater than the synthesis of real sea water, because the value of electrolytes activation synthesis of sea water is greater than the real sea water. It can be concluded that the increase in flow rate and concentration, can increase the generated of power density.

The influence of microwave irradiation on the chitosan hydrolysis catalyzed by cellulase enzyme was studied. The hydrolyzed chitosan was characterized by measuring its viscosity and reducing sugar. Further, it was also characterized by Fourier-Transform Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD), and Scanning Electron Microscope (SEM). The classical Michaelis-Menten kinetic parameters were measured by analyzing the amount of reducing sugars. The results were compared with the hydrolysis by using conventional shaker incubator. The hydrolysis reaction time needed to obtain similar reducing sugar yield was significantly lower for microwave irradiation than shaker incubator. On the other hand, the reduction rate of the relative viscosity was significantly higher for the hydrolysis of chitosan using shaker incubator. A significant difference in chemical structure was observed between hydrolysis using microwave irradiation and shaker incubator. Overall, the result showed that the hydrolysis behavior of chitosan using microwave irradiation is significantly different with using shaker incubator.

Air merupakan kebutuhan dasar bagi manusia, kebutuhan akan air bersih terus meningkat seiring dengan pertumbuhan manusia. Jumlah air di bumi cenderung tetap, namun kualitas air terus menurun akibat pencemaran. Oleh sebab itu perlu adanya upaya pengolahan air menjadi air bersih sebelum di konsumsi. Semarang selatan merupakan sebuah kecamatan di Kota Semarang yang memiliki posisi strategis karena dekat dengan kota. Letak daerah yang berada pada daerah padat penduduk mengakibatkan sulitnya akses air bersih. Air yang diambil dari air sumur memiliki kualitas yang kurang bagus dimana air yang dihasilkan sedikit keruh dan berbauh amis. Selama ini warga berinisiatif menggunakan tawas sebagai bahan untuk menjernihkan air, namun residu tawas dalam air menyebabkan gangguan kesehatan pada tubuh. Oleh sebab itu, pengolahan menggunakan membran diterapkan untuk mengolah air tersebut menjadi lebih bersih. Teknologi membran tidak membutuhkan bahan kimia tambahan serta biaya operasi yang cukup murah. Kegiatan penyuluhan teknologi membran untuk mengolah air bersih telah dilakukan di Kelurahan Bulustalan Rt 02 RW 03 Kecamatan Semarang Selatan. Sebagai luaran dan juga hasil dari pengabdian ini, dibuatlah makalah/modul pelatihan perancangan filtrasi membran skala rumah tangga untuk mengolah air sumur tercemar menjadi air bersih yang layak konsumsi..
