Ekologi Keong Darat Di Taman Nasional Gunung Ciremai

ABCTRACTThe Ecology of Landsnail in Ciremai National Park. Twice fieldworks in order tocollect landsnails of Ciremai National Park were conducted, approximately in ArgamuktiVillage of western part of the park and Linggajati Village of eastern part of the park.They resulted 48 species of landsnails of 15 families. Thirty two species were found inArgamukti whereas 28 species were found in Linggajati. However, biodiversity indexescomparison for both locations were unsignificant at 95% level of confidence. Bothlocations were also populated by specific landsnails, only 40% of the whole landsnailswere live in Argamukti and Linggajati. The highest densities in entire locations weredominated by microsnails and mostly were live in lower latitude. Cluster analysis forspecies and habitat used NTSYSpc 2.10p. programs for Jaccard similarity index revealed6 groups of species and habitats respectively

Keong Darat Diplommatina Spp (Moluska, Gastropoda) Di Taman Nasional Gunung Ciremai

Land Snail Diplommatina spp (Mollusc, Gastropoda) at Ciremai Mountain National Park.The microscopies of land snail Diplommatinids depend on the water resources. This memberof mollusc can be used as a forest indicator. The results of the study shown that 50% JavanDiplommatinids found in this park. The study also indicated that Palatungan, Linggarjati andApuy (Argamukti) has Shannon and Weiner diversity: 1.33, 0.85, and 0.84, respectively

Snails Composition in the Southern Part of Gunung Halimun National Park

Snails inventory in the southern part of Gunung Halimun National Park (GHNP) was conducted in two locations i.e., Ciptarasa and Simaresmi,in July and November 2000.It was found 36 species of snails that belongs to 16 families.It means that snails in the southern part of GHNP differs from that of the central part of the Park. Those snails were discovered in 9 habitat types

Kajian Tekno Ekonomi Migrasi Jaringan Berbasis XDSL ke FTTx GPON di Daerah Perkotaan

Penelitian dan pengembangan teknologi dibidang telekomunikasi menghadapi tantangan utamayaitu meningkatnya kebutuhan bandwidth secara signifikan dari tahun ketahun. Permasalahan yang dihadapi di Indonesia saat ini adalah sebagian besar jaringan telekomunikasi broadband masih mengunakan DSL berbasis kawat tembaga sebagai media utama akses jaringan. Kondisi ini jika tidak diantisipasi oleh operator penyedia jasa jaringan telekomunikasi, memungkinkan terjadinya bottleneck ketika bertambahnya kebutuhan akan konvergensi layanan telekomunikasi seperti triple-play service. Oleh karena itu dibutuhkan suatu kajian tekno ekono mimigrasi jaringan akses untuk sebagai dasar pemilihan teknologi beserta aspek ekonominya yang dapat memenuhi tuntutan tersebut. Tujuan penelitian ini adalah melakukan kajian tekno-ekonomi terhadap migrasi jaringan DSL berbasis tembaga keteknologi jaringan FTTx GPON pada daerah perkotaan menggunakan metode STEM (Strategic Telecom Evaluation Model). Metode tersebut berbasis pada pembagian kelas densitas rumah tangga pada area tertentu menjadi empat kelas kepadatan yaitu; sangat tinggi, tinggi, sedang dan rendah. Dari hasil kajian diperoleh untuk daerah dengan kepadatan rumah tangga sangat tingi dan tinggi jaringan akses layak secara teknologi dan ekonomi untuk migrasi dari jaringan berbasis kabel tembaga kelayanan berbasis kabel optic FTTx GPON, untuk daerah dengan kepadatan sedang dilayani oleh dua teknologi yaitu VDSL dan GPON, sedangkan untuk daerah kepadatan rendah hanya dilayani oleh teknologi VDSL. Dengan demikian operator dapat menggunakan hasil kajian ini untuk mendukung pengambilan keputusan dalam rangka migrasi jaringan akses

Dinamika Populasi Atactodea Striata (Gmelin, 1791) (Mollusca: Mesodesmatidae) Di Pantai Berpasir Ohoider, Kep. Kei Kecil, Maluku Tenggara

Atactodea striata (Gmelin, 1791) are inhabitants of the sandy at Village Ohoider, Kei Kecil Islands, MalukuTenggara. Sampling has been carried out on the 15th of September 1997 to October 1998 for the shell heightmeasurement. Monthly length frequency data were then analyzed using the software FiSAT II to estimatepopulation parameters such as population structure, age maximum, maximum length, growth and recruitment.Result obtained from this study is that Atactodea striata shells generally consist of four age groups, except in certainmonths were widened to five because of the occurence of old shell group. Mussels in this study reproducemultivoltine with expected life span of almost four years. The maximum length of the mussels is 19.03 mm at 95%confidence level, and the growth coefficient K = 0.37 with a growth performance index φ '= 1.74. Observations onhabitat sediment discovered that these shells prefer to live in the fine sand with range of fire grain of 65.96 to69.09%

Peningkatan Hasil Belajar Murid dalam Pembelajaran IPA Menggunakan Metode Inkuiri di Sekolah Dasar

The aim of this study is generally to obtain accurate informsi to improve the learning outcomes of students in the fourth grade science teaching in State Elementary School 38 Mempawah Hulu.Metode used is deskriptif.Taedapat increase the ability of teachers to plan lessons learned from the first cycle is 2,67 with category of "enough" and then on the second cycle with a value of 3.35 with the "good" category. of s ", then on the second cycle with a value of 3.35 with the" good "category. To implement the learning phase occurs also an increase from the first cycle with average scores of 2.87 with enough categories and increased in the second cycle with an average score of 3.65 "good" category. There is an increase in learning outcomes at baseline 65.71 with the percentage of completeness 72% the first cycle, then increased significantly by an average of 78.51 percentage completeness 98% in the second cycle. The average value of the first cycle to the second cycle 72.11 with both categories
