ABSTRAKTujuan dari penelitian ini adalah untuk mengetahui perbedaan pertumbuhan Sargassum sp.yang dibudidaya dengan sistem budidaya yang berbeda di Teluk Ekas Lombok Timur. Jenispenelitian ini adalah penelitian eksperimen.. Sampel dalam penelitian ini adalah tanamanSargassum sp yang dibudidayakan dengan sistem budidaya yang berbeda yaitu : rakitterapung dan rakit patok dasar. Pengolahan data dilakukan dengan menggunakan paketprogram komputer pengolahan data yaitu SPSS 16. Pengujian hipotesis dilakukan denganmenggunakan uji-t polled varians, dengan taraf signifikan 0,05 dan taraf kepercayaan 95 %,diperoleh t-hitung 11,974 > t-tabel 1,987, atau berdasarkan besarnya nilai probabilitas yangditunjukan, diperoleh probabilitas-hitung 0,00 < probabilitas-tabel 0,05, sehingga Ho ditolakdan Ha diterima, ini artinya terdapat perbedaan pertumbuhan Sargassum sp. yang dibudidayadengan sistem budidaya yang berbeda.Kata-kata kunci: Sargassum sp., Teluk Ekas, Sistem budidaya yang berbeda.ABSTRACTThe purpose of this research is to determine growth differences of Sargassum sp., werecultured with different cultivation systems in the Ekas Bay of East Lombok. This research isan experimental research. The sample in this research is Sargassum sp. of cultivated cropswith different cultivation systems, such as : floating raft and raft basic stakes. Processing datewas performed by using a processing date computer program package SPSS 16. Hypothesistesting is done by using t-test polled variance, with a significance level of 0.05 and a level ofvalid 95 %, in order to obtain t count 11.974 > t - table 1,987, or based on the value of theindicated probability, probability-count obtained 0.00 < 0.05 probability- table , so that Ho isrejected and Ha accepted , this means that there are differences in the growth of Sargassumsp. were cultured with different cultivation systems.Key words: Sargassum sp., Ekas bay, Different Cultivation System.

The new release of the computer program packageWinXPRO v.3xfor determination of the crystal properties from parameters of the multipole-modeled experimental electron density and anharmonic atomic displacement coefficients is described. The set of properties is significantly extended by using the density functional and information theories. In addition, a built-in multi-functional viewer and programs to display the output data, including the mapping of the chosen functional bonding descriptors onto surfaces of the other properties, are included.

AbstractThe straightforward strategy of building a chiral C-O bond directly on a general carbon radical center is challenging and stereocontrol of the reactions of open-chain hydrocarbon radicals remains a largely unsolved problem. Advance in this elementary step will spur the development of asymmetric radical C-O bond construction. Herein, we report a copper-catalyzed regioselective and enantioselective carboesterification of substituted dienes using alkyl diacyl peroxides as the source of both the carbon and oxygen substituents. The participation of external acids in this reaction substantially extends its applicability and leads to structurally diverse allylic ester products. This work represents the advance in the key elementary reaction of intermolecular enantioselective construction of C-O bond on open-chain hydrocarbon radicals and may lead to the discovery of other asymmetric radical reactions.
