EFFECT OF POLYVINYLPYRROLIDONE ADDITIVE ON MEMBRANE CHARACTERISTICS IN THE PREPARATION OF POLYETHERSULFONE HOLLOW FIBER MEMBRANE Syahril Ahmad
Jurnal Kimia Terapan Indonesia Vol 3, No 2 (1993)
Publisher : Research Center for Chemistry - LIPI

Preparation by applying the dry - wet spinning method and characterization of polyethersulfone (PES) hollow fiber membranes for ultrafiltration purpose have been studied. The characteristics of the hallow fibers studied include water flux, rejection rate, molecular weight cut - off and cross section structure. The membrane was prepared using the dope solution composition of 20% PES, 6% Polyvinylpyrrolidone (PVP) and 74% of n-Methyl Pyrrolidone as solvent. The effect of molecular weight of PVP and the small amount of water added in the dope solution have also been studied. The results show that increasing the molecular weight of PVP in the dope solution will decrease the rejection coefficient of the membrane towards dextran solution. Effect of a small amount of water in the dope solution as wetting agent is not obvious as indicated by the fluctuations in the results. Higher operating pressure during ultrafiltration process give higher water flux, but the effect on membrane rejection is not clear. By taking the rejection coefficient as 90 %, the molecular weight cut-off of the hallow fiber prepared are 40,000; 80,000; 25,000 and 110,000.

Cross section of polysulfone membranes hollow fiber spun bydry - wet process have been studied. Composition of membraneobserved composed of 16% Polysulfone (PS) , 64% dimethylAcetamide (DMAc) as solvent and 18% Polyetylene glycol (PEG)as additive. Molecular weight of polyetylene glycols used were 200,300 and 400 Daltons. Fiber of membranes were charaterized bydextrane solution to find rejection coefficient and molecular weightcut - off of the membrane. Cross sections of hollow fiber membraneswere observed by Scanning Electron Microscopy (SEM).Results of the experiment show that, molecular weight ofpolyethylene Glycol additif used in spinning of hollow fibermembrane affects form of cross section of substructure andmolecular weight cut - off the membrane obtained. This researchwas aimed to predict the pore size of membrane made based onmolecular weight of additive used.

Concentration of protein which found in freshmilk, sweet ketchup and salt ketchup have been done byusing hollow fiber polysulfone membrane with differentmolecular weight cut - off (MWCO). Membranes usedin these experiments have MWCO 66,000, 87,000 and 149,000 Dalton. Experimental were conducted bycontinues flow system and parameters observed in these experimental were protein, sugar and salt, respectively.Protein infresh milk rejected by membrane above 98 %,but all of sugar pass through to the permeate side. Forsweet ketchup feed sample, rejection coefficient towardsprotein was smaller than feed fresh milk. The higherrejection coefficientfor sweet ketchup was 48 % for themembrane with MWCO 66.000 Dalton. Rejectioncoefficient of membrane towards protein for salt ketchup sample was smaller than sweet ketchup sample. For saltketchup, the higher rejection coefficient towards proteinwas 27 % for the membrane with MWCO 66,000Dalton. Rejection coefficient of membrane towardsNaCl for feeding solution sweet ketchup and saltketchup were in the rlJ.1Jgefrom 8.74 to 23.96 %.Key words : Hollow fiber membrane, ultrafiltration, protein,milk, ketchup.

This research aims to determine the influence of features, product variations and ease of transactions on mobile banking user satisfaction at sharia banking financial institutions in Jambi City. This research used a quantitative approach which was carried out by distributing questionnaires to 112 Mobile Banking users in Jambi City. The methods used in this research are instrument tests (validity and reliability tests), classical assumption tests (normality, multicollinearity and heteroscedasticity tests) and multiple liner analysis along with statistical tests (t test, F test and R2 Determination Coefficient). The results of this research show that features have a positive and significant effect on user satisfaction which can be determined using the t test with a significance value of 0.001 < 0.05 and a value of tcount > ttable, namely 3.426 > 0.198217. Product variations have a positive and significant effect on user satisfaction as evidenced by the significance value of 0.001 < 0.05 and the tcount > ttable value, namely 3.577 > 0.198217. ease of transactions has a positive and significant effect on user satisfaction which can be seen with a significance value of 0.001 < 0.05 and a value of tcount > ttable, namely 3.385 > 0.198217. Simultaneously, features, product variations and ease of transactions have a positive and significant effect on mobile banking user satisfaction at sharia banking financial institutions which can be seen from the F test, namely fcount > ftable or 40.058 > 2.69 and the resulting significance value is 0.000 < 0.005. The determinant coefficient value is 0.514 or 51.4% and the remaining 0.486 or 48.6% can be explained by other variables outside this research.

This thesis is entitled The Role of Waqf Land in Improving the Economic of the Temiang Island Community in Tebo Ulu. This research uses qualitative research methods. The types and sources of data needed are primary data and secondary data. Data collection techniques are carried out by means of observation, interviews and documentation, while data analysis methods include data collection, data reduction, data presentation and drawing conclusions. The results of this research show the role of Waqf Land in improving the economic welfare of the people of Temiang Island in Tebo Ulu, namely that many people depend on the income they get from trading in the market and most people fulfill their needs. From a spiritual aspect, it provides very positive results and the role of waqf land which is managed as an elementary school building becomes a forum for the local community to teach children and provide insight. The obstacles faced by the management of the role waqf are the lack of competent human resources and the status of the role waqf land does not yet have a certificate and there is a lack of ways to educate the people on Temiang Tebo Ulu Island. The solution that can be implemented is to increase human resources by providing training and guidance to the community and the management of the Nurul Ihksan Mosque and increasing socialization to the community regarding waqf both online and in person
