Judul: Dampak Ketersediaan Infrastruktur terhadap Kesejahteraan Masyarakat: Analisis Kabupaten/Kota di Indonesia 2009-2011
Abstrak: Infrastructure is very important complementary goods for economic development. Ensuring the availability of infrastructure will encourage the economic activity in the region and an increase in income per capita. Economic development has not only contributed to the revenue but has also contributed to the welfare. The purpose of this study is to analyze the availability of infrastructure to the community welfare in Indonesia. This study used panel data, cross section of 155 districts/cities in Indonesia, 2009-2011 time series data, and using six variables, namely the Human Development Index, the density of road, water, electricity, schools, and hospital beds. The analysis showed Human Development Index for all provinces in Indonesia has increased in the period of 2009-2011. Analysis of panel data method showed the water infrastructure, electricity, schools, and hospital beds had a positive effect on the welfare of the community, while the availability of density of road infrastructure is not significant on the welfare of the community., Infrastruktur merupakan barang komplementer yang sangat penting untuk pembangunan ekonomi. Terjaminnya ketersediaan infrastruktur dapat mendorong kegiatan ekonomi wilayah dan peningkatan pendapatan per kapita. Pembangunan ekonomi tidak hanya memberikan kontribusi terhadap pendapatan tetapi memberikan kontribusi terhadap kesejahteraan. Tujuan penelitian ini adalah menganalisis ketersediaan infrastruktur terhadap kesejahteraan masyarakat di Indonesia. Penelitian ini menggunakan metode panel data, data cross section dari 155 kabupaten/kota di Indonesia, data time series periode 2009-2011, dan menggunakan enam variabel, yaitu Indeks Pembangunan Manusia, panjang jalan per wilayah, air, listrik, sekolah, dan tempat tidur rumah sakit. Hasil analisis metode data panel menunjukkan ketersediaan infrastruktur air, listrik, sekolah, dan tempat tidur rumah sakit berpengaruh positif terhadap kesejahteraan masyarakat, sedangkan ketersediaan infrastruktur panjang jalan per wilayah tidak berpengaruh signifikan terhadap kesejahteraan masyarakat.

Judul: Pengaruh Ketersediaan Infrastruktur terhadap Ketimpangan Pendapatan dan Kemiskinan Kota dan Desa di Indonesia: Analisis Data Provinsi.
Abstrak: Infrastruktur memiliki peran yang penting dalam pembangunan ekonomi nasional. Pembangunan ekonomi tidak hanya memberikan kontribusi terhadap pertumbuhan ekonomi tetapi memberikan kontribusi terhadap semakin kecilnya kemiskinan serta ketimpangan pendapatan. Tujuan penelitian ini adalah menganalisis ketersediaan infrastruktur terhadap ketimpangan pendapatan dan tingkat kemiskinan kota dan desa di Indonesia. Penelitian ini menggunakan metode panel data, data cross section dari 33 provinsi di Indonesia, data time series periode 2007-2016, dan menggunakan enam variabel, yaitu Indeks Gini, persentase penduduk miskin, panjang jalan, air, listrik, sekolah, danjumlah rumah sakit. Hasil analisis metode data panel menunjukkan ketersediaan infrastruktur air, listrik dan rumah sakit berpengaruh positif terhadap ketimpangan pendapatan sedangkan ketersediaan infrastruktur panjang jalan dan jumlah sekolah tidak berpengaruh signifikan terhadap ketimpangan pendapatan. Pengaruh ketersediaan infrastruktur terhadap kemiskinan di Indonesia, dari lima variabel bebas yang digunakan, empat diantaranya terbukti berpengaruh signifikan dalam menurunkan kemiskinan baik di perkotaan maupun di pedesaan, yaitu ketersediaan infrastruktur air, listrik, infrastruktur panjang jalan, dan rumah sakit .

Judul: Mud Crab’s (Scylla serrata Forskal 1775) Response to Different Decaying Level of Gold Snail (Pomacea canaliculata Lamarck 1822) Bait.
Abstrak: Mud crab is well known as omnivorous-vigorous-voracious-opportunistic-scavenger. These intertidal animals applies mainly chemoreception in their predatory behaviour. It has been commonly assumed that non fresh gold snail bait is better than fresh bait in stimulating the mud crab. This research's aim is to analyze mud crab response to different decaying level of gold snail bait. Their response were observed as time required to touch the bait and pattern and direction of the mud crab in approaching the baits. The different decaying level of gold snail baits were shown on Total Volatile Base Nitrogen (TVBN) as 16.3 mg/100g (0 day); 534.1 mg/100g (3 days); and 887.4 mg/100g (6 days). The research was conducted from July 2009 until February 2011. The TVBN test for gold snail baits were conducted at Laboratory of BBPPHP Jakarta. The experiment was conducted in Pemalang. The result showed that the average period of mud crabs to touch the baits were 52.14 minutes; 61.57 minutes and 52.57 minutes. Anova test concluded no sufficient evidence of significant effect of TVBN content of gold snail bait on mud crab’s feeding behaviour. Movement pattern B, i.e. left and right deviation followed by straight forward movement to the bait, was commonly exhibited by the crabs. Consequences of time period required by the mud crab to approach the bait on fishing operation is discussed.
