Judul: Keterkaitan antara Ketersediaan Infrastruktur dan Tingkat Kemiskinan di Indonesia: Analisis Data Kabupaten/Kota 2008-2011
Abstrak: Poverty in Indonesia is gradually decreasing in 2008-2011. The infrastructure availability is one of the most important points that can accelerate poverty reduction. This study uses panel data of 155 districts/municipalties in Indonesia 2008-2011. The goals of this study are to describe the condition of the infrastructure availability and the poverty rate in Indonesia and to analyze the relationship between them .The infrastructure variables that are used consist of water, electricity, roads, schools, and hospital beds. Beside that, control variables that are applied are GDP per capita and unemployment rate (TPT). The result of the study shows that infrastructure availability generally has a significant impact except infrastructure of schools and has a negative relationship for poverty rate except water’s infrastructure. From all those five infrastructure variables, the variable which has the most effective influence on the percentage of poor people is electricity variable.

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: Organ reproduksi beberapa jenis ganggang cokelat dan merah
Abstrak: Penelitian organ reproduksi telah dilakukan terhadap beberapa jenis ganggang cokelat dan meran. Ganggang cokelat yang diperiksa termasuk famili Sargassaceae, meliputi Sargassum cristaefolium, S. echinocarpum, S. plagyophyllum, S. siliquosum, Turbinaria conoides, T. deccurens dan T. ornata. Organ reproduksi pada famili ini berupa percabangan fertil disebut reseptakel. Di dalam reseptake! terdapat konseptakel tempat organ reproduksi betina (oogonium) dan jantan (antheridium). Hasil pemeriksaan menunjukkan bahwa oogonium dan antheridium pada semua sampel yang diamati dapat dijumpai pada konseptakel yang sama atau berbeda, tapi masih terdapat dalam individu yang sama kecuali pada S. siliquosum oogonium dan antheridium terdapat pada individu yang berbeda. Pada ganggang merah berhasil diamati organ reproduksi betina (sistokarp), jantan (spermatia) dan spora (tetraspora). Sistokarp Gigartina sp. 1, Gracilaria coronopifolia, Rhodymenia linearis dan R. palmata berupa bulatan-bulatan yang menonjol dan tersebar di permukaan talus. Sistokarp pada Laurencia intrica dan Laurencia sp. terdapat di daerah korteks, sedangkan pada Galaxaura obtusata dan G. oblongata sistokarp terletak pada bagian medula. Spermatia Chondrococcus hornemannii, L. intrica dan R. linearis tersebar di daerah korteks. Tetraspora pada Ceramium fastigiatum terletak di percabangan khusus, sedangkan tetraspora Gracilaria textorii, Gigartina sp. 2, Gracilaria sp. 1, Hypnea valentiae dan Laurencia intrica terletak di daerah korteks. Seluruh tetraspora yang diamati bertipe tetrahedral kecuali pada Gigartina sp. 2 bertipe zonat. Research on reproductive organ has been carried out on species of both brown and red algae.. Observation on the brown algae included Sargassum cristaefolium, S. echinocarpum S. plagyophyllum. S. siliquosum. Turbinaria conoides, T. deccurens and T. ornata, that belong to Sargassaceae. The reproductive organ of this family is called receptacel, i.e. fertile branches. The receptacel hold conceptacel that consists of either oogonium (female reproduction organ) or antheridium (male reproduction organ), or both. Oogonium and antheridium may be located in the same conceptacel or separated in the different one of the same individual (monoecious), except those of S. siliquosum are separated in the different individual (dioecious). Both female and male organ (called cystocarp and spermatia respectively), together with tetraspores have been observed in red algae. The cystocarps of Gigartina sp. 1, Gracilaria coronopifolia, Rhodymenia linearis and R. palmata are spherical, widespread, protruding out from thallus surface. Cystocarp of both Laurencia intrica and Laurencia sp. are located in cortex, while those of Galaxaura obtusata and G. oblongata, are located on medulla. Spermatia Chondrococcus hornemannii, Laurencia intrica and Rhodymenia linearis spread in the cortex. The tetraspores of Ceramium fastigiatum are located in a particular branch, while that of Gracilaria textorii, Gigartina sp. 2, Gracilaria sp. 1, Hypnea valentiae and Laurencia intrica are located in cortex. All of the tetraspores observed are tetrahedral, except those of Gigartina sp. 2 are zonate.
