Abstract

Penentun metode komputasi untuk analisis hubungan kuantitatif struktur dan aktivitas (HKSA) telah dilakukan pada senyawa turunan triazolopiperazin amida sebagai inhibitor enzim DPP IV yang merupakan penyebab diabetes melitus tipe 2 (DM2). Metode komputasi yang digunakan untuk analisis ini adalah metode semiempirik. Analisis dilakukan dengan pemodelan struktur senyawa turunan triazolopiperazin amida dan perhitungan deskriptor HKSA dilakukan menggunakan program Hyperchem. Parameter yang digunakan adalah pergeseran kimia 13C NMR, panjang ikatan antaratom, sudut ikatan antaratom, dan muatan atom bersih. Hasil perhitungan parameter tersebut dibandingkan dengan data empiris dan hasil perhitungan metode ab initio. Hasil penelitiannya menunjukkan bahwa metode semiempirik yang sesuai untuk analisis HKSA senyawa turunan triazolopiperazin amida adalah AM1 dan PM3.

Abstract

Quickly recognize drug resistance in Mycobacterium tuberculosis is very important for the efficiency of the treatment and control of the disease. More than 95% of RIF resistance occurs due to point mutations in the 81-bp region of the rpoB gene M. tuberculosis. Generally, the mutation occurs at codon 531, 526 and 516. One of method to detect the mutation is using ARMS-PCR. In order to apply the ARMS-PCR technique to detection of mutations needed a special and specific primer. Primer design process using computer software "Primer Designer" and the specificity was confirmed with "Bioedit". Accuracy and ability of all these primers to detecting mutation in rpoB gene M. tuberculosis tested using ARMS-PCR method. PCR amplification results were then analyzed using the techniques of electrophoresis on agarose 1.5%. Electrophoresis results showed two bands produced from the amplification with the template H37RV (wild type). Both bands are expected to be in a position 238 bp and 484 bp, in the other hand the result amplification with the template from mutant strains produce one band with sized 484 bp. From these data it is known that ARMS-PCR reactions are performed can be used to detect mutations in the rpoB gene of M. Tuberculosis.

Abstract

Plastik merupakan bahan polimer sintesis yang dibuat melalui proses poli- merisasi dimana tidak dapat lepas dari kehidupan kita sehari-hari yang umumnya kita jumpai dalam bentuk plastik kemasan ataupun penggunaannya pada alat-alat listrik dan peralatan rumah tangga. Sifatnya yang sulit terdegradasi di alam menjadikannya penyumbang limbah terbesar yang menyebabkan rusaknya keseimbangan alam. Tiga cara penanggulangan limbah plastik yang meliputi mengurangi penggunaan kantong plastik dengan menggantinya dengan alat (kain) untuk membungkus barang atau dikenal dengan furoshiki ; pengolahan limbah plastik menggunakan metode fabrikasi; dan penggunaan plastik biodegradable yang lebih mudah terurai di alam. Tiga cara tersebut diharapkan dapat menjadi solusi bagi penanggulangan limbah plastik.

Abstract

Degradation of Metanil yellow has been done. In this research the degradation process was done by photolysis and sunlighting method by using TiO2-SnO2 catalysis. The residu of metanil yellow was centrifuged and measured by UV/Vis Spectrophotometer at 300 – 600 nm after degradation. 6 mg/L of Metanil yellow and addition of 0,03 g TiO2-anatase and SnO2 for 150 min, gave the percentage of degradation 27,38 % and 25,00 % after photolysis. 6 mg/L of Metanil yellow and addition of 0,03 g TiO2-anatase and SnO2 for 150 min, gave the percentage of degradation 94,84% and 93,25% after lighted by sun with 1,13256 1015 foton cm-2/s intensity. From the results percentage of degradation showed that degradation with the addition of TiO2-anatase and SnO2 can improve the degradation of methanil yellow. The percentage of degradation proves that the addition of TiO2-anatase and SnO2 which is lighted by sun is better than photolysis process.

Abstract

Skin damage will impair human health. One of the causes of skin damage are free radicals form ultra violet rays. Antioxidants are needed to stabilize free radicals. Alternative sources of antioxidants which can be used to block the effects of free radicals on the skin are skin lotion of fruit black mangrove (Rhizophora mucronata Lamk.) and sunscreen of waste corn cob (Zea mays L). Mangrove fruit methanol extract shown to function as a source of natural antioxidants, which have very strong antioxidant activity, so the lotion containing fruit extracts exact mangrove can be used as inhibitors of free radicals on the skin. In addition, it has been proven that the active compound contained in a corn cob has the ability as a sunscreen active ingredient, with the highest SPF value.

Abstract

The experiment about the food to cauting decent from starch of sago using powder of bar sago palm as filler and glycerol as plastisizer has done. Biodegadation of to cover eat decent eith powder of bar sago palm as filler, was done by soil buriar test for 5 – 3 days. Mean while biodegadation in Aspergillus niger media was done for 3-5 days. The results of weight loss percentage showed that all to cover eat decent can be biodegadation rate. The biodegadability by soil burial test was more faster thant by Aspergillus niger fungi. Characterization of fungtional goups were done by FT – IR and the morphology was tested by SEM. Toxicity test using E.Coli in Nutrien Agar media at temperature 370C and incubation 48 hours showed that to cover eat decent not indivcatoin of anticeptic properties.

Abstract

This research was conducted at Kulon Progo coastal area of Daerah Istimewa Yogyakarta Province. The objectives were to define geoecosystem units spread by examining constituent parameters of coastal geoecology system, to evaluate suitability of existing settlement zone regarding the characteristic of geoecology type, to inventory environment issues and to set the direction of settlement zone development which accommodates the characteristic of geoecology type. This research used geoecology approach based on geomorphology process and landform as a basic setting of geoecosystem unit as an analytical unit. The Method used was a survey using stratified random sampling technique. Data analysis was arranged descriptively and by spatial modeling using Arc Gis version 9.3 software. This research produced the identification of geoecosystem units in this area.The identified largest area were dominated by coastal alluvial plain geoecosytem unit and sand dunes geoecosystem unit ,by 2.685,461 Ha (43,05%) and 1.986,121Ha (31,84%), respectively. Old beach ridge geoecosistem unit and coastal alluvial plain were the most suitable, based on geoecology characteristic, as a direction of settlement area zonation development. This recommendation of comprehensive settlement zonation was set to solve whole environment issues and integrated by involving whole stakeholders. Keywords :

Abstract

The consideration of sustainability, sustainable development, or sustainable future began to emerge in the beginning of 18th century, precisely after the Brundtland Commission Report had been published in 1987. In the beginning, environmental awareness rose in the industrial country such as European countries and America. It is the consequence of the industrial revolution which had caused negative impact to the environment. Furthermore, climate change and global warming have become a great issue. Buildings gave contribution in this issue due to their consuming energy and releasing emissions. Therefore, the use of appropriate material is a key point of green building. Some considerations of material selection for green building are resource efficiency, indoor air quality, energy efficiency, water conservation, and affordability. These aspects are analysed in traditional house’s materials. The result from this qualitative approach shows that the materials used in traditional houses are green. There are some lessons that can be drawn from this local wisdom. They could be very useful for the future design of buildings.
