Research showed that two genotypes of bPit-1/HinfI gene were identified in this study i.e GG (0.90) and AG (0.10) with allele frequencies of 0.05 (A) and 0.95 (G). The polymorphic informative content (PIC) and number of effective allele (ne) values were 0.09 (low) and 1.11. respectively. The Chi-square (χ2) value in the population studied was 0.20 and in Hardy-Weinberg equilibrium (χ2<5.99). It was concluded that the polymorphism of bPit-1/HinfI in Pasundan cattle included of low category and was not associated with body weight

Sistem Informasi Geografis Mencari Rute Lokasi Travel Di Kota Palangka Raya Berbasis Website

Transport service or usually called travel1 is an inter-city transportation that many people use in Palangkaraya to travel among the cities. However, many people do not know the location of transport services in Palangkaraya and the informations obtained is still limited. Thus a system that provides computerized geographic information is needed. This study discusses the mapping of locations of transport services, location search, location data filters and the determination of the shortest path using the Dijkstra algorithm. For system development, it will apply the waterfall method. It is expected that the availability of a web-based system as a place to provide geographic information on the location of travel services is presented using the Google map API. In this study, the testing results for determining the shortest route on the public transport route can be determined by the Dijkstra algorithm. The transportation route is considered as a directed and weighted graph; the point represents a stop, and; side is as a vehicle lane. In the testing, firstly the user&nbsp; inputs the starting point on the map then looks for the destination on the destination search map, the system will display the initial shortest route output to the destination

Polymorphism of Bovine Growth Hormone Receptor Gene (g.3338A>G) and Its Association with Body Measurements and Body Weight in Pasundan Cows

Bovine growth hormone receptor (bGHR) gene was one of the growth hormone family genes that important for body growth and development of cattle. This research was carried out to identify the polymorphism in the exon 10 of bGHR gene from 142 heads of Pasundan cows at West Java and its association with body length (BL), withers height (WH), heart girth (HG), and body weight (BW). There are two mutation points in the bGHR gene based on the sequencing analysis i.e. g.3322del.A and g.3338A&gt;G. The single nucleotide polymorphism (SNP) at g.3338A&gt;G was detected using PCR-RFLP method with AluI restriction enzyme and showed three genotypes of AA (0.49), AG (0.37), and GG (0.14). The allelic frequencies were 0.67 (A) and 0.33 (G). The number of allele effective (ne) value was 1.79 and described that A allele was the higher allele in the bGHR gene in this study. The polymorphic informative content (PIC) value was 0.34 and categorized as a moderate category. The Chi-square (χ2) analysis showed that the population sample was in the Hardy-Weinberg equilibrium (χ2&lt;5.99). It was concluded that the polymorphism of bGHR gene had a significant association (p&lt;0.05) with BL, WH, and BW of Pasundan cows. Research showed that all body measurements in GG genotype animals were lowest than other genotypes. Meanwhile, the highest of BW was showed in GG genotype. In addition, the average of BL, WH, HG, and BW in Pasundan cows (2 PPI and 3PPI) were 126.88±14.25 cm; 133.97±31.69 cm; 145.35±13.56 cm and 201.85±44.87 kg, respectively

Jembatan Apung Gunung Jati dengan Pondasi Pontoon tanpa Menggunakan Tiang Penyangga sebagai Solusi Transportasi Darat Penghubung Jawa-sumatera

Indonesia as an archipelagic country has an area of 1,910,931.32 km2 with a population density reached 237.36 million in 2010, with thus Indonesia has great potential to enhance the natural resources, and human resources that can not be separated from life on the islands of Sumatra and Java. Java and Sumatra is an island that has the potential to promote development in the country. Marine transportation is used as a link the two islands has many shortcomings, such as not able to serve the needs of people who want to cross the island of Java and Sumatra, well, because it is hampered fleet size is limited, and expensive ferry freight rate. This is a barrier for people crossing, due to the fact that private vehicles and cargo that want to cross had to queue up for hours to wait penyebarangan. See the underwater topography of Sunda strait vulnerable plate movement and saplings Krakatoa makes conventional bridge construction is a solution that is not quite right. Therefore, the construction of the floating bridge is the most appropriate solution as a means of land transportation connecting Java and Sumatra. Floating bridge pontoon which we propose to use as a replacement solution using a conventional bridge foundations are stuck at the bottom of the sea surface, it would disrupt the ecology of the sea bottom and the underwater topography is possible will often occur and transfersal longitudinal vibration caused by magma activity under the sea. With the construction of pontoon bridges can reduce the risks and obstacles that occur during the development progresses. By using the laws of physics Archimides building construction and design of a concept which has been updated from existing bridge in Washington DC / Seattle, Gunung Jati bridge is believed to be able to address the challenges that exist in the Sunda Strait. The problem of water flow down will not impact directly on the foundation materials floating pontoon bridge is made more profitable than conventional bridges using pole foundation rooted on the seabed

Novel magnetite nanoparticles coated with waste sourced bio- based substances as sustainable and renewable adsorbing materials

This study examines the possibility of using bio-based product isolated from urban solid wastes as a material for environmental technological applications. To this end, Fe3O4 nanoparticles coated with different amounts of soluble bio-based products (SBO) were synthesized as low-cost nanoadsorbent for the removal of pollutants in wastewater. Particles of 10 nm diameter with Fe3O4 core and SBO shell were obtained. The concentration of SBO employed in the synthesis had no effect on the size and structure of the NPs, but ruled the pHPZC and aggregation of the nanoparticles in water. The cationic dye crystal violet (CV) was used as a model pollutant to test the adsorption capacity of the nanoparticles. The results indicated that both the medium pH and NP dosage were significant parameters to enhance the removal of CV. The results contribute to the studies which show how wastes can become a source of revenue through the industrial exploitation of their chemical value.Fil: Magnacca, Giuliana.
