Published: March 2017

The development of analytical method for the determination of α-endosulfan and bifenthrin residues in tea has been done. The complex matrices and also the pigment were the challenge in doing quantification of the pesticide residues in tea matrices. In order to get appropriate analysis method for the determination of pesticide residues in tea, the modification was done in the analytical method for the determination of organochlorine multiresidue in non fat matrices: seasoning and spicy that is published by Directorate General of Food Crops, Directorate of Food Plant Protection. The modification was done particularly in clean-up step to remove the interferences from the extract of tea matrices such as the pigment that usually interfere the measurement with Gas Chromatography (GC). The result showed that the MDL value for both analytes were 0.5 ng/g that were much lower than MRLs. The percent recovery obtained from the method was 78.58 and 90.19% for α-endosulfan and bifenthrin, respectively. The precision of the analysis method for both analytes were good since the % RSD values were below than the Horwitz’s value that was 19.18% at spiking level concentration of 300 ng/g.

Published: March 2017

The influence of cross-linking and membrane hydrophilicity on the transport rate had been studied using a membrane prepared from a mixture of chitosan/PVA cross-linked citric acid (PVA.cl.CA) for creatinine and urea transport. The optimum mole ratio of PVA:citric acid as well as the best composition of chitosan:PVA.cl.CA were determined using creatinine transport study. Using the optimum compositions, further study was done using different thickness of the membrane in transporting creatinine, urea and a mixture of 3 species (creatinine, urea and vitamin B12). Membrane characterization was done using FT-IR spectrophotometer, water absorption test, TG/DTG and SEM. The results showed that the optimum composition PVA:citric acid was obtained to be 90:1, having % WU of 113.74% and creatinine transport percentage of 18.16%. Meanwhile, the optimum composition of chitosan:PVA.cl.CA was found at 4:6 ratio having % WU and % transport of 136.67% and 24.26%, respectively. The optimum transport capacity was found for membrane thickness of 50 µm with WU% at 139.61% and the percent transport of creatinine and urea each was 38.93% and 60.36%. The presence vitamin B12 in the solution of is proved to disturb the transport of creatinine and urea through the membrane. Finally, hydrophilicity seemed to give substantial contribution in the transport process as well as the mechanical strength of the membrane.

Published: March 2017

Air particulate matter concentrations, black carbon as well as elemental concentrations in two semi industrial sites were investigated as a preliminary study for evaluation of air quality in these areas. Sampling of airborne particulate matter was conducted in July 2009 using a Gent stacked filter unit sampler and a total of 18 pairs of samples were collected. Black carbon was determined by reflectance measurement and elemental analysis was performed using particle induced X-ray emission (PIXE). Elements Na, Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Cu, Zn and As were detected. Twenty four hour PM2.5 concentration at semi industrial sites Kiaracondong and Holis ranged from 4.0 to 22.2 µg m-3, while the PM10 concentration ranged from 24.5 to 77.1 µg m-3. High concentration of crustal elements, sulphur and zinc were identified in fine and coarse fractions for both sites. The fine fraction data from both sites were analyzed using a multivariate principal component analysis and for Kiaracondong site, identified factors are attributed to sea-salt with soil dust, vehicular emissions and biomass burning, non ferrous smelter, and iron/steel work industry, while for Holis site identified factors are attributed to soil dust, industrial emissions, vehicular emissions with biomass burning, and sea-salt. Although particulate samples were collected from semi industrial sites, vehicular emissions constituted with S, Zn and BC were identified in both sites.

Published: March 2017

Identification of Protein-Ligand Interaction Fingerprints (PLIF) has been performed as the rescoring strategy to identify the best pose for the docked poses of indomethacin-(R)-α-ethyl-etanolamide (IMM) in the binding site of cyclooxygenase-1 (COX-1) from simulations using PLANTS molecular docking software version 1.2 (PLANTS1.2). Instead of using the scoring functions included in the docking software, the strategy presented in this article used external software called PyPLIF that could identify the interactions of the ligand to the amino acid residues in the binding pocket and presents them as binary bitstrings, which subsequently were compared to the interaction bitstrings of the co-crystal ligand pose. The results show that PyPLIF-assisted redocking strategy could select the correct pose much better compared to the pose selection without rescoring. Out of 1000 iterative attempts, PyPLIF-assisted redocking simulations could identify 971 correct poses (more than 95%), while the redocking simulations without PyPLIF could only identify 500 correct poses (50%).These works have also provided us with the initial step of the construction of a valid Structure-Based Virtual Screening (SBVS) protocol to identify COX-1 inhibitors.

Published: March 2017

Biogasoline have been synthesized through catalytic hydrocracking reaction against FAMEs compounds (fatty acid methyl esters) obtained from the transesterification of Nyamplung seed oil. The performance of Al-MCM-41 and Pd/Al-MCM-41 as the catalytic hydrocracking was compared. In this research, the influence of Pd impregnation into Al-MCM-41 catalyst on the characters and catalytic activity has been evaluated. The characters determined were crystallinity by using X-Ray Diffractometer (XRD), Si/Al ratio by Inductively Coupled Plasma (ICP), the acidity by pyridine adsorption, the surface area and pore volume by surface area analyzer and the morphology by Scanning Electron Microscopy (SEM). Catalytic activity was examined for hydrocracking of free fatty acid methyl esters (FAMEs) produced from the transesterification of Nyamplung seed oil, by Hydrogen flowing. The research result showed that impregnation of Pd into Al-MCM-41 has been successfully carried out, which did not destroy the structural morphology of the catalyst. It was also discovered that the Pd impregnation could increase Si/Al ratio and the acidity but it leads to decrease in the catalyst surface area and the volume. Furthermore, Pd impregnated Al-MCM-41 showed superior activity compared to Al-MCM-41 for FAMEs hydrocracking. The superiority was indicated by higher effectiveness and yields selectiveness, that were 100% hydrocarbon composed of C9-C18 that was dominated by C12 emerging the gasoline fraction, compared of that by the results used Al-MCM-41 catalyst that were 97% hydrocarbon consisted of C8-C20 with equal abundance.

Published: March 2017

The objective of this research was to investigate the effect of gamma irradiation on mechanical and thermal properties of fish gelatin films prepared from scales of Lates calcarifer. The films were irradiated by gamma rays at varied doses (0-50 kGy). The mechanical and thermal properties of irradiated gelatin films were measured by using colorimeter, Universal Testing Machine, Differential Scanning Calorimetry (DSC), and Fourier Transform Infrared (FTIR) spectrophotometer. The results showed that increasing of irradiation dose up to 50 kGy, the color of irradiated film did not change significantly (p < 0.05). The tensile strength of irradiated film was increased with no differences among dose variation but there was no change on elongation at break value (p < 0.05). The DSC spectra of irradiated gelatin films showed that irradiation did not affect melting temperature (Tm). In contrast, the glass transition temperature (Tg) of irradiated film has slight tendency to increase with increasing of radiation doses. In general, the FTIR spectra confirmed that gamma irradiation up to 50 kGy affected the mechanical properties of gelatin films.

Immobilization of humic acid (HA) onto chitosan using tosylation method with 1,4-butanediol as a spacer arm has been evaluated. Chitosan was phthaloylated selectively using phthalic anhydride in dimethylformamide as solvent with addition of 5% water (v/v) as cosolvent prior to be tosylated. N-phthaloyl-chitosan and HA were tosylated using tosyl chloride in excess and triethylamine as catalyst at temperature < 10 °C for 12 h. The 6-O-tosyl-N-phthaloyl-chitosan was reacted with 1,4-butanediol in order to obtain a spacer arm attached chitosan. The 6-O-butanol-N-phthaloyl-chitosan was activated by reacting with tosyl chloride. For evaluation on immobilization of HA on chitosan with and without spacer arm, 6-O-tosylbutane-N-phthaloyl-chitosan was reacted with HA and the 6-O-tosyl-N-phthaloyl-chitosan was reacted with HA. The HA immobilized onto chitosan was characterized by XRD and FTIR spectrophotometric method. The result showed that HA can be immobilized covalently onto chitosan after attaching 1,4-butanediol as spacer arm onto 6-O-tosyl-N-phthaloyl-chitosan and activating the product with tosyl chloride, but HA cannot be reacted directly onto 6-O-tosyl-N-phthaloyl-chitosan.

Published: March 2017

To meet the energy needs and ensure the productive performance of ruminants, it is necessary to ensure adequate energy intake. An important characteristic of fat is its high energy value, provide more energy than carbohydrates. The lipids used in the feed increases the capacity for absorption of liposoluble vitamins and have physical, chemical and physiological which are important in food processing, in animal nutrition and provides enhanced palatability. However, undesirable levels in the diet can cause problems in the rumen of the animal. Thus the use of protected fat has no effect on the absorption of nutrients, does not cause a reduction in the digestibility, since the same is intact in the rumen normal levels of pH and is metabolized in the intestine where there is a better utilization. The use of this alternative energy source is increasing and bringing good results to producers, improving reproductive and productive traits.

The hospitalization of ill animals increases the risk of infections. The veterinarian has the obligation to minimize the risk of additional damage that could be subsequent to their interventions and that includes minimizing patient exposure to infections that could lead to a nosocomial infection, considering that, in some cases, the infection can be zoonotic. The main goal of this work was to evaluate the contamination levels in the operation room of small animals of the Veterinary Hospital of the University Center of the Octavio Bastos Educational Foundation (Unifeob), in São João da Boa Vista, SP, and to develop an educational project that focus the critical points that arose in order to maintain surgical infection control in Small Animals. Results show that in the samples took in the surgical environment during the night there is a great risk of fungus growth. In the samples that were taken from the table and floor, the majority of the time, there was fungus and bacteria growth, with the exception of the samples took after surgery, in which case you can say that there was predominant growth of bacteria. It was also observed that the largest number of colonies were found in the plaque next to the operation room door, in comparison to the other doors around the room due to greater transit of people. A positive result was obtained by changing the pavement gloves routine that suggested as a way to decrease the contamination that was found in the gloves immediately before the surgery.

Brazil is one of the major world powers for fish-farming, with a fishing and aquaculture production volume reaching more than one million tons in 2004. National Aquaculture production is growing on average 21.1% annually, surpassing statistically other activities of national importance such as cattle farming. However the per capita consumption is low, about 6 kg per year due to the high cost of the final product and eating habits that value the consumption of bovine meat. The meat of the fish is a source of high biological value protein, and is rated as nutritionally beneficial to human health by being an important source of essential aminoacids, vitamins, minerals and fatty acids. The fish can be marketed as fresh, chilled or frozen, the first one being the national preference. Inspection of the product to be marketed should be carefully observed, evaluating the organoleptic characteristics and presence of parasites found in the flesh. When the fish are cultivated, so are all sea food creatures, are subjected to factors that lead to stress and as a consequence may arise concomitant diseases, particularly parasitic diseases, which are a risk to public health since some of these parasites cause zoonosis. The increasing incidence of parasitic zoonosis are associated with the consumption of raw fish or insufficiently cooked, and food habits that encourages ingestion of this type of meat, such as sushi and sashimi of eastern culture. The main parasitic zoonosis is transmitted by this inadequate consumption are anisakiasis, eustrongiliase the capilariase the fagicolose the clonorquiose and diphyllobothriasis. Until this moment, there are few reports of parasitic diseases in humans in Brazil, probably due to lack of diagnosis and not by the absence of disease in the country. The sanitary inspection of products fish derivated is still scarce and studies concerning the importance of fish parasites in our country are reduced. Thus the best recommendation would be preventive abstinence from consumption of raw fish or meat not cooked properly, but heat treatment like cooking, is able to eliminate the parasite activity both in their adult and larval form, and freezing at -20 º C for seven days, or -35 º C for not less than fifteen hours, is also described as effective in eliminating these parasites. Health authorities, fish-farmers, veterinarians should seek greater control with regards to fish diseases of zoonotic character, from production to marketing of fish, to decrease the morbidity and mortality of the livestock, improve the quality of fish for consumers avoiding, for a prophylactic measure, the spread of zoonosis transmitted by fish.

RFID (Radio-Frequency IDentification) merupakan sebuah teknologi compact wireless yang diunggulkan untuk mentransformasi dunia komersial. Sebagai suksesor dari barcode, RFID dapat melakukan kontrol otomatis untuk banyak hal. RFID adalah sebuah teknologi yang memanfaatkan frekuensi radio untuk identifikasi otomatis terhadap obyekobyek atau manusia. Kenyataan bahwa manusia amat terampil dalam mengidentifikasi obyek-obyek dalam kondisi lingkungan yang berbedabeda menjadi motivasi dari teknologi ini. Sistem pembayaran dengan menggunakan teknologi RFID dapat dilakukan secara swalayan dengan mudah dan cepat. Penggunaan teknologi ini dapat memudahkan dan mempercepat transaksi pembelian dan dilakukan oleh pembeli itu sendiri. Mereka hanya mendekatkan semua barang yang dibeli kepada alat reader RFID, dan setelah selesai mereka menekan tombol total dan diakhiri dengan mendekatkan kartu pembayaran (sejenis kartu debit atau kartu kredit). Dengan didekatnya kartu yang telah diberikan mikro chip sebagai alat pembayaran tersebut, maka saldo uang pembeli yang berada di kartu tersebut berkurang. Transaksi ini menjadi cepat dan mudah karena tidak diperlukannya uang pengembalian dan dapat dilakukan secara mandiri oleh pembeli.

Dengan ditetapkannya Peraturan Menteri Komunikasi dan InformasiNo.07/P/M. KOMINFO/3/2007, yang ditandatangani MenkominfoSofyan Djalil, pada 21 Maret 2007, tentang Standar Penyiaran DigitalTeresterial untuk Televisi Tidak Bergerak di Indonesia, disebutkanbahwa Pemerintah menetapkan DVB-T sebagai standar penyiaran TVdigital untuk pengguna tidak bergerak di Indonesia. Teknologi TVdigital ini dipilih karena memiliki banyak kelebihan dibandingkandengan TV analog. Teknologi ini punya ketahanan terhadap efekinterferensi, derau dan fading, serta kemudahannya untuk dilakukanproses perbaikan (recovery) terhadap sinyal yang rusak akibat prosespengiriman/transmisi sinyal. Perbaikan akan dilakukan di bagianpenerima dengan suatu kode koreksi error (error correction code)tertentu. Teknologi ini juga mampu memultipleks beberapa programsekaligus, di mana enam program siaran dapat ”dimasukkan” ke dalamsatu kanal TV berlebar pita 8 MHz, dengan kualitas jauh lebih baik.Berdasarkan hal tersebut diatas, maka TVRI sebagai TV publikmemerlukan suatu perencanaan strategi yang tepat karena hal ini bisamenjadi peluang sekaligus tantangan baik yang bersifat teknologis,ekonomis, maupun psikologis. Dengan menganalisa data yang adadengan analisa matrik internal dan eksternal, SWOT dan matrik grandstrategy maka posisi LPP TVRI berada pada kuadran II yakni posisi WO(weakness – opportunity) aggressive maintenance, maka diperlukanstrategi-strategi sebagai berikut: membeli peralatan transmisi dan studioberteknologi digital secara bertahap, meningkatkan kualitas SDM gunamendukung pelaksanaan penyiaran TV digital dan memperbaikiperalatan transmisi yang rusak (analog) sehingga masyarakat yg kurangmampu masih dapat menangkap siaran TVRI dengan baik.

Analisa Simulasi Performansi Penggunaan Orthogonal Frequency Division Multiplexing Pada Sistem Digital Video Broadcasting-Terrestrial
Authors: Astuti Dian Widi
Published: March 2017

Orthogonal Frequency Division Multiplexing (OFDM) merupakan suatu teknik transmisi yang menggunakan beberapa buah frekuensi pembawa (multicarrier) dalam satu saluran dimana setiap frekuensi pembawa tersebut saling orthogonal (tegak lurus). OFDM banyak dipakai untuk sistem komunikasi wireless mengingat kemampuan dari OFDM mengatasi multipath fading yang menyebabkan terjadinya intersymbol interference (ISI). Dampak dari ISI tersebut adalah penerima tidak dapat membaca sandi informasi dengan benar sehingga mengurangi performasi sistem komunikasi digital. Cara OFDM mengatasi ISI adalah dengan menggandakan simbol dan menambah simbol secara periodik yang digunakan sebagai guard interval. Penambahan dari guard band yang terlalu lebar bisa mengurangi throughput data yang dikirimkan. Fading juga menyebabkan amplitudo dan phasa berfluktuatif sehingga cara untuk mengatasinya adalah estimasi kanal (Channel Estimation) dengan menyisipkan simbol pilot pada pengiriman frame OFDM sehingga penerima dapat memperkirakan karakteristik kanal dan dapat mengembalikan data yang terkirim. CE terdiri atas comb-type pilot channel estimation dan block-type pilot channel estimation. DVB-T sebagai penyiaran televisi digital terestrial juga memakai OFDM dengan skema modulasi OFDM tambahan yaitu berupa pilot simbol atau yang lebih dikenal dengan estimasi kanal (Channel Estimation). Mengingat jumlah subcarrier dari DVB-T cukup besar jika dibandingkan dengan aplikasi lain yang menggunakan OFDM maka perlu dilakukan sebuah penelitian tentang analisa performasi penggunaan OFDM untuk sistem DVB-T terhadap perubahan guard interval, modulasi dan penggunaan kanal pada estimasi kanal tersebut.
