Abstract

Artikel ini melaporkan tentang sintesis, karakterisasi dan kinerja membran polyethersulfone (PES) yang dimodifikasi dengan aditif polyvinyl pyrrolidone (PVP) dengan tujuan untuk meningkatkan kinerja dan sifat antifouling membran. Membran PES modifikasi dibuat dengan penambahan 0,5% PVP sebagai aditif, menggunakan pelarut dimethyl sulfoxide (DMSO) dan n-methyl pyrrolidone (NMP). Pengaruh penambahan aditif dalam sistem membran dievaluasi dengan menganalisa perubahan struktur kimia menggunakan fourier transform infrared (FTIR), perubahan morfologi permukaan menggunakan scanning electron microscopy (SEM), uji kuat tarik menggunakan tensile strength meter, uji porositas membran dengan menggunakan metode gravimetri, serta pengujian kinerja filtrasi, dan sifat antifouling. Hasil analisa struktur membran dengan SEM menunjukkan adanya pengaruh jenis pelarut dan penambahan aditif terhadap perubahan morfologi membran. Selain itu modifikasi membran juga meningkatkan porositas, kinerja fluks permeasi serta sifat antifouling membran. Hasil uji filtrasi membran menunjukkan perolehan permeabilitas air pada membran D-0,5 dan N-0,5 masing masing sebesar 47,5 L/m2.jam.atm dan 41,5 L/m2.jam.atm dengan sifat antifouling membran modifikasi lebih besar dibandingkan dengan membran tanpa modifikasi. Synthesis, Characterization, and Performance of Hydrophobic Membranes Using Polyvinyl Pyrrolidone (PVP) as Additives. This paper discusses the synthesis, characterization and performance of polyethersulfone (PES) membranes modified with polyvinyl pyrrolidone (PVP) additives in order to improve the performance and antifouling properties of membranes. The modified PES membrane was prepared by adding 0.5% PVP as an additive, using dimethyl sulfoxide (DMSO) and n-methyl pyrrolidone (NMP) as solvents. The effect of adding additives to the membrane system was evaluated by analyzing changes in chemical structure using fourier transform infrared (FTIR), changes in surface morphology using scanning electron microscopy (SEM), tensile strength test using tensile strength meter, membrane porosity test using the gravimetric method, as well as testing the filtration performance and antifoulingproperties. The results of membrane structure analysis by SEM showed the influence of the type of solvent and additives on changes in membrane morphology. In addition, membrane modification also increases porosity, permeation flux performance, and membrane antifouling properties. The results of the membrane filtration test showed that the water permeability of D-0.5 and N-0.5 membranes was 47.5 L/m2.h.atm and 41.5 L/m2.h.atm, respectively, with modified membrane antifouling properties larger than the membrane without modification.

Abstract

This paper proposed adsorbent development by synthesizing polyurethane foam (PUF) using a simple method, mixing polyol with isocyanate and adding fillers of bentonite and magnetite to the PUF matrix. The study's main objective was to produce a PUF-based adsorbent with high reactivity to remove Hg2+ in wastewater. This bentonite and magnetite filler-modified polyurethane foam (BMPUF) adsorbent was fixed in a bed column for the adsorption of mercury (II) ions from an aqueous solution. The effect of initial Hg2+ concentration on the removal rate and the effect of contact time on adsorption efficiency was investigated. Langmuir, Freundlich, and BET non-linear models were taken into account to determine the best adsorption isotherm fitting and obtain adsorption capacity, intensity, and pore volume. As a result, it followed the non-linear Freundlich model, and the average adsorption capacity and intensity were 0.466 mg/g and 0.923, respectively. The average BET-based pore volume obtained was 0.782 L/mg. The kinetics study showed that the non-linear pseudo-first-order kinetics model was more suitable for describing the Hg2+ adsorption kinetics. The maximum equilibrium adsorption capacity was 1.770 mg/g with the adsorption rate of 0.0013 min-1 based on the non-linear model. The effect of varying bentonite and magnetite ratio on adsorption isotherm and kinetics was also investigated. Overall, the potential application of BMPUF adsorbent in the adsorption of mercury (II) ions was demonstrated in the current study.

Abstract

Kabupaten Aceh Jaya is a very potential Aceh patchouli production center. The development of the patchouli industry sector in Aceh faces serious challenges, especially the capacity building of farmers towards good agriculture practices, and innovation and technology. This study aims to identify the level of empowerment of farmers and the affecting factors. The study employed a questionnaire survey to 88 samples from 383 populations. Data analysis used a descriptive method and chi-square test. The results show that a low level of farmer empowerment is predominantly. The weakest elements are the ability to cooperate and solidarity; meanwhile, the ability to overcome obstacles is the highest, followed by the awareness and desire to change, and the ability to increase capacity to gain access. Farmer's perceptions on the group institutions, and program intervention have a significant association with empowerment, while the perception to characteristics of the social systems has no relationship. Therefore, the role of empowerment innovation is necessary for capacity building.
