Judul: Disparitas Antar wilayah dan Determinan Pertumbuhan Ekonomi di Provinsi Jawa Barat dan Banten
Abstrak: The economy of a region portrayed through economic growth as well as one indicator to see the results of the development that has been done and is useful for determining the direction of future development. In infrastructure development, government's role as a very strategic mobilizer in supporting economic growth, anddisparityof regional became decreasing and development expected to convergence. West Java Provincial Government has developed the initial concept development and two three Metropolitan Growth Center. This concept was developed by considering the strategic position of Metropolitan Areas (Bodebek Karpur, Bandung and Cirebon) as the center of population agglomeration, and economic and social activities, as well as Growth Center (Palabuhanratu and Pangandaran) as the center of economic growth that has the potential for growth and development of the region in another areas and macro conditions in Indonesia. Policy to accelerated development of the region through increased economic growth and reduction of disparities to push economic growth, followed by the even distribution of income. Past studies have shown that the development of infrastructure such as transport infrastructure, electricity and telecommunications networks and the provision of clean water is essential in order to improve the economy in a region. Infrastructure facilities needed not only by households but also by the business community. Infrastructure improvements are expected to bring prosperity and accelerate economic growth. Areas with adequate infrastructure has a greater advantage in attracting investment into the region, causing the area will be growing faster than areas with poor infrastructure. This is due to the opening of the isolation of the area so that access to the various factors of production may be possible to open up the movement of the region's economy. The purpose of this study is: First, analyze the regional economic disparities district/ City in the province of West Java and Banten. Second, Testing the convergence between the district/ city in the province of West Java and Banten approach Gross Regional Domestic Product. Third, analyze the determinants of disparities between regions and economic growth in the Province of West Java and Banten. Based results of research on disparities between regions and the determinants of economic growth in the Province of West Java and Banten in the period 2004 to 2010 can be drawn some conclusions as follows: (1) Economic growth in the City and County in West Java and Banten from 2004 to 2010 was very volatile. The results of calculations using Williamson indeks 2004 to 2010 in the province of West Java and Banten quite high. (2) Infrastructure development in Indonesia during the period of 2004 to 2010 in general has increased. Beta convergence of GDP Banten value greater when separated with West Java during joining West Java. The half Life needed to close the gap in Banten faster than in West Java. (3) The result of disparities between regions and estimate the determinants of economic growth based on existing data indicates that the electrical and water variables influence positively the regional economic growth. Water infrastructure elasticity is greater than the elasticity of electricity infrastructure. While the road infrastructure influence negatively effect the

Judul: Pola Pewarisan Karakter Suara Kicauan Pada Burung Perkutut
Abstrak: Turtledove (Geopelia striata) is a singing birds that has a better melodious voice. The inheritance of this character has not been determined, so that research on the voice inheritance is important. This study was aimed to characterize the voice patterns turtledove. Materials consisted of 12 pairs of parents and their progenies. Twelve of their turtledove was ranked based on their sound quality. The parameters observed included voice patterns, the presence of elements of sound, the type of sound, harmonious sound (frequency and level of sound intensity) and duration of the total sound. Voice analysis was done by using computer software Cool Edit Pro version 2.1. Sound visualization was displayed in waveform shape. Sound intensity level was determined using the formula TI = 10 log I/I0, with the value I0 at 10-12 W/m2. Based on the inheritance analysis sire voices is a better chance in herediting of the voice and the number of beats sound of the middle voice. Dam plays an role in giving voice rhythm modification and sound tip inheritance. Based on the sound analysis, sound quality the voice rank from the highest to the lowest were: ♂AK, ♂ FQ, ♂HHa, ♂ ISS, ♂HRR, ♂ BL, ♂CM, ♂ EQ, ♂GQ, ♂DO, ♂DN, and ♂DP. The frequency value and the highest intensity level displayed by AK turtledove were 929.49 Hz and 91.5 dB, whereas the lowest value displayed by ♂DP were 633.59 Hz, and 67.83 dB. The best rhythm of the turtledove indicated by high frequency with a stable pattern, harmonious the intonation, as well as clear basic voice.
