Abstract

Penelitian tentang gastropoda terestrial telah dilakukan pada kebun karet, cokelat, dan sawit di perkebunan Bogorejo Kecamatan Gedongtataan Kabupaten Pesawaran Provinsi Lampung. Tujuan penelitian ini adalah (1) untuk mengetahui keanekaragaman gastropoda terestrial di kebun karet, cokelat, dan sawit dan (2) untuk mengetahui kepadatan gastropoda terestrial di ketiga macam kebun tersebut. Metode pemilihan lokasi yang digunakan adalah metode purposive, kemudian dilakukan random sampling. Analisis gastropoda terestrial menggunakan keanekaragaman serta, kepadatan. Keanekaragaman gastropoda menggunakan indeks keanekaragaman Shannon-Simpson. Hasil penelitian memperlihatkan bahwa di kawasan perkebunan karet, cokelat, dan sawit ditemukan 10-20 species gastropoda terestrial dengan kepadatan berkisar antara 27,85-201,18 indiv/m2, serta indeks keanekaragaman (H’) berkisar antara 1,73- 2,64. Keanekaragaman dan jumlah spesies gastropoda terestrial tertinggi ditemukan di kebun karet, sementara itu kepadatan tertinggi ditemukan di kebun cokelat.

Abstract

ABSTRACTThis study aimed to quantify the population of Birgus latro in the Batudaka di Togean islands, Central Sulawesi. The research on robber crab was conducted in Batudaka Island, Togean, Tomini Bay, Central Sulawesi. In the study site, 21 plots measuring of 50x50 m2 were created bounded by raffia. Feed in the form of shredded coconut is placed in each plot in the afternoon. At night was performed observations and catchs. In the "base camp" every crab crab carapace caught measured in carapace length and weight. During the study, 277 crabs were caught, consisted of 173 males (62.45%) and 104 (37.55%) females. Based on the formula calculation of Schiller (1992) population figures obtained 821 803 ± 195 030 crabs in Batudaka Island. By regression analysis between carapace length with weight, it was found that the growth of B. latro is negative allometric, i.e., weight gain is faster than the increase length of carapace. The weight gain of female is slightly higher than that of the male. Whether male crab population or female equally composed of 9 age groups. This study showed that 66.7% of male crab and 29.1% of female crab has entered the market size.Keywords: Birgus, crab, carapace

Abstract

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%.Keywords:: Dynamics Population, Atactodea striata, Kei Kecil Islands, Maluku Tenggara

Abstract

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.Keywords: ecology, landsnail, biodiversity, density, cluster

Abstract

Research on the diversity of snails in Enggano, Central Bengkulu was held on 16 April 2015 to 5 May 2015 by taking three sampling sites that are north-western part of Enggano (Kampung Bendung at Desa Banjarsari and Desa Meok), the centralpart of Enggano (Desa  Malakoni) and the south-easternpart of Enggano (Desa Kaana). Sampling was conducted using purposive sampling while the analysis using graphical method and statistical cluster and t-test. This study found 722 specimens of snails which consists of 24 species from 17 families. Most of the snails found are in small size. Land snails in the forest dominates the north-easternpart as much as 88.2%. compared to  freshwater snails (11.8%). Terrestrial and freshwater snails share amount 50% each in the forest of the central, while terrestrial snails still dominate in the forest of south-eastern part (land snails: snail freshwater = 71.4%: 28.6% ). The existence of land snails and freshwater can not be separated from the state forests themselves besides the condition of the soil and surface water as a result of the topography of the island

Abstract

Buah murbei kaya antioksidan karena kandungan antosianin yang banyak. Sayangnya,  pemanfaatannya sebagai sumber antioksidan di Indonesia masih  minim. Pemanfaatan tanaman murbei hanya sebatas daun yang dijadikan pakan ternak dan teh. Penelitian ini bertujuan untuk melakukan karakterisasi antosianin buah murbei spesies Morus alba dan Morus cathayana. Karakterisasi antosianin ekstrak buah murbei Morus cathayana dan Morus alba dilakukan menggunakan pelarut 0,1% asam klorida (HCl)  dalam metanol dan dianalisis menggunakan spektrofotometer UV-tampak dan Kromatografi Cair Kinerja Tinggi (KCKT). Hasil serapan spektra UV-tampak yang diperoleh dari ekstrak kasar menunjukkan spektra serapan ekstrak buah M. cathayana memberikan nilai yang lebih tinggi ± 1,3 a.u dibandingkan serapan yang diperoleh dari ekstrak kasar buah M. alba dengan serapan ± 0,4 a.u. Nilai total antosianin yang diperoleh dari M. cathayana sebanding dengan serapan ekstrak segarnya, yaitu 40,39 ± 7,64 mg/g berat kering dibandingkan  M. alba yang memiliki nilai total antosianin 11,57 ± 3,02 mg/g berat kering. Hasil kromatogram dari KCKT menggunakan kolom XR-ODS dengan pengelusi A adalah 0,1% asam formiat dalam asetonitril dan pengelusi B adalah 0,1% asam formiat dalam air menunjukkan baik M. cathayana maupun M. alba memiliki dua pigmen antosianin dominan. Walaupun bergitu, intensitas kromatogram M. cathayana lebih tinggi dibandingkan intesitas pada M. alba. Nilai intensitas M. cathayana adalah 50 mAU untuk waktu tambat 7,86 menit dan 15 mAU untuk waktu tambat 8,38 menit. Nilai intensitas M. alba adalah 10 mAU untuk waktu tambat 7,35 menit dan 3 mAU untuk waktu tambat 7,76 menit. Dua antosianin dominan pada M. alba dan M. cathayana  diprediksi  merupakan sianidin-3-O-glukosida dan sianidin-3-O-rutinosida.

Abstract

ABSTRACTThis paper presents the results of a survey on intertidal molluscs in 3 habitats (Seagrass bed, coral reef, and sandflat) in Tanimbar Islands of West South-east Moluccas, Indonesia. Six relatively large and two small islands were attained to perform 125 plots of 34 stations. Molluscs’ diversity in each habitat were calculated using Shannon-Wiener formulation whereas Mann-Whitney formulation for comparing between habitats. Multivariate analyses for clustering of PAST 2.17 was utilized to further the analyses. A number of 101 species gastropods (26 families) and 51 species of bivalves (19 families) were recorded. Seagrass bed was inhabited by 100 species, followed by coral reef by 85 and sandflat by 44 species. Shannon-Wiener indexes for molluscs’ diversity range in seagrass was 0.39 to 1.29, in coral was 0.27 to 1.14 and in sandflat was 0.52 to 0.99. Clustering analyses for stations revealed that three stations in seagrass were the most dissimilar, followed by one station in coral due to habitat. Clustering analyses for species found four dissimilar groups of molluscs, whereas a group has many consimilar members.Keywords: Seagrass, coral, sandflat, diversity, clustering
