Abstract

The objective of this research was to investigate the kinetics aspect of Hg and Pb adsorption using coal fly ash. A series of a Hg and Pb adsorption experiment using coal fly ash with contact time variation was carried out. The results were plotted to pseudo first order kinetic, pseudo second order kinetic and intra-particle diffusion model. High values of R2 were obtained from the plots of kinetics model for both heavy metals investigated, these values exceeded 0,8. The conclusion obtained was that Hg adsorption kinetics followed pseudo second order kinetic model while Pb adsorption kinetics followed intra-particle diffusion.

Abstract

Water pollution caused by heavy metals is a serious problem to environment. Hg and Pb are heavy metals having high toxicity level. Heavy metals treatment is necessary before releasing them to environment. The use of adsorption method is interesting because of its relatively simple operation. The development of adsorption is oriented to the use of industrial waste such as coal fly ash. The objective of this research is to investigate the kinetics aspect of Hg and Pb adsorption using coal fly ash. A series of a Hg and Pb adsorption experiment using coal fly ash with time variation was carried out. The results were plotted to pseudo first order kinetic and pseudo second order kinetic model. The conclusion obtained was that Hg and Pb adsorption kinetics followed pseudo second order kinetic model

Abstract

AbstractThe seawater fishery in Dusun Sine has the higher potentials, due to its location near the coastal area of Sine Beach. In general, the people in Dusun Sine make a living as sea fishermen. However, the income of the marine fishing community has not maximized because the community still uses the conventional marine product processing production system, so that the marketing of processed marine fish products is also limited. As an effort to increase the selling value of processed marine fish, the International Community Service Group empowers fishermen's wives in Sine Hamlet by conducting several activity programs in the form of socializing the manufacture of modern marine processed products in the form of Sine Foodies, home industry food (PIRT), and the use of e-commerce. This activity was held to use a health protocol and through a presentation method on product marketing licensing in the form of PIRT socialization and marketing of processed marine fish products with e-commerce as well as demonstrations on the process of making processed marine fish products in the form of shredded fish and fish balls using attractive packaging. Participants in the socialization were fishermen's wives, village cadres, and prospective entrepreneurs from Kalibatur Village.Keywords: Assistance, processed marine fish products, Processing, Licensing management, MarketingAbstrakSektor perikanan air laut yang ada di Dusun Sine, Desa Kalibatur, Kecamatan Kalidawir, Kabupaten Tulungagung, memiliki potensi yang sangat tinggi. Hal ini disebabkan letaknya yang berada di dekat wilayah pesisir Pantai Sine. Secara umum, masyarakat di Dusun Sine bermata pencaharian sebagai nelayan laut. Namun, pendapatan masyarakat nelayan laut belum maksimal karena masyarakat masih menggunakan sistem produksi pengolahan hasil laut secara konvensional, sehingga pemasaran produk hasil olahan ikan laut juga terbatas dengan seadanya. Sebagai upaya untuk meningkatkan nilai jual hasil olahan ikan laut, Tim Pengabdian masyarakat Departemen Kimia, Fakultas Sains dan Teknologi, Universitas Airlangga dengan didukung penuh oleh Kelompok mahasiswa KKN Internasional, FST, UNAIR melakukan upaya pemberdayaan para istri nelayan di Dusun Sine dengan melakukan beberapa program kegiatan berupa sosialisasi pembuatan hasil olahan laut secara modern berupa Sine Foodies, pangan industri rumah tangga (PIRT), serta penggunaan e-commerce. Kegiatan ini diselenggarakan menggunakan protokol kesehatan dan melalui metode presentasi mengenai perijinan pemasaran produk berupa sosialisasi PIRT dan pemasaran produk hasil olahan ikan laut dengan e-commerceserta demonstrasi mengenai proses pembuatan produk hasil olahan ikan laut yang berupa abon ikan dan bakso ikan dengan menggunakan kemasan yang menarik. Peserta sosialisasi adalah para istri nelayan, kader desa, dan calon pengusaha yang berasal dari Dusun Sine, Desa Kalibatur. Kata Kunci: Pendampingan, Produksi makanan olahan hasil laut, Pengurusan perijinan, Pemasaran

Abstract

Carbon nanodots (CNDs) have widely received great attention as a result of favorable optical, electrical, optoelectrical, biocompatible, and non-toxic properties these nanoparticles possess. However, the exploration of nanoparticle from natural raw material was limited. In present work, the carbon dots were produced from catechin isolated from Uncaria gambir through a simple and facile process. Carbon nanodots were further produced by the pyrolysis process of catechin, which allowed it for carbonization. Owing to its unique properties such as photoluminescence with an emission peak at 500 nm (lex = 380 nm), average size diameter about 5 nm and non-toxic; Cat-CNDs were incredibly potential for staining targeted tumor cells. The staining ability by confocal microscopy observations showed their green fluorescence images which meant that the CNDs easily penetrated HeLa cells via endocytosis. The resulting CNDs which were analyzed using some significant techniques approved that the prepared Cat-CNDs were tremendously dispersible and water-soluble, good colloidal stability, excellent biocompatibility, favorable hydrophilicity, high photostability, and non-toxicity.

Abstract

Candida albicans often form polymicrobial biofilms along with pathogenic microbes. Silver nanoparticles (AgNPs) were well known to have strong antimicrobial activity. However, their effect on polymicrobial biofilms and the mechanism has never been reported. This study aimed to synthesize AgNPs and study their effects on polymicrobial biofilm represented by C. albicans–E. coli biofilm. Polymicrobial biofilms, formed by clinical isolates of C. albicans and E. coli, were developed from the standardized suspensions of each strain by culturing flat-bottom 96-well microtiter plates for 48 h, then treated with AgNPs. Cell viability was assessed using the tetrazolium salt reduction assay; the extent of biofilm formation was measured by crystal violet staining. AgNPs reduced the polymicrobial biofilm in two ways: by degrading the extracellular matrix and killing both C. albicans and E. coli. The results showed AgNPs is a potential new approach for developing potent anti-biofilms.

Abstract

The improvement in the design of mordenite-based catalysts focuses on the present study to fulfill the massive demand for bio-aviation fuel (BAF) as renewable energy. Modification of the mordenite through ionic impregnation of Fe, Cu, and Cr, has supported the mordenite to perform with better efficiency and activity in catalyzing the cracking process of stearic acid. The adjustment on catalytic activity was carried out by simply reacting the catalyst with stearic acid at 190 °C and investigating cracking products with Gas Chromatography-Mass Spectroscopy. The results of the GC-MS test of the cracking product showed the formation of alkane-alkene and aromatic compounds. BAF was selectively obtained (30.27%) when the reaction was catalyzed by FeCuCr/mordenite catalyst. The BAF derived from FeCuCr/mordenite contained hydrocarbons that include xylene, mesitylene, dodecane, tridecane, tetradecane, and pentadecane. However, reduced selectivity was realized (19.85%) when the reaction was catalyzed by nano FeCuCr/mordenite. Its hydrocarbon constituents include benzene, tetradecane, and pentadecane compounds.
