One therapy of DM is a-glucosidase inhibitor. a-Glucosidase is an enzyme that can break down a complex carbohydrate into simple sugar. lhe inhibiton of this enzyme can retard the rate of carbohydrate digestion resulting in a delay in glucose absorption. The purpose of  this studywas to identify the content of chemical compound and to test the a-glucosidase inhibitory activity in ethanolic extracts of some plants used as antidiabetic. a-Glucosidase inhibitory activity test carried out by spectrophotometric method. The simplisia powder was extracted by reflux using 80% ethanol. Based on a-glucosidase inhibitory activity test, all the plant extracts were active in inhibiting a-glucosidase. lhe three most active extracts were Ceiba pentandra (L.) Gaetern bark extract, Saccharum offcinarum root extract, and Persea americana Mill. bark extract with IC50 of 5.16, 10.35 and 10.83 ppm, respectively. They contain glycoside, tannin, and saponin. The test results of the kinetics enzyme inhibition showed that Randu bark extract had  competitive inhibitory activity.

Abstract

Pabean Bay is an estuary that has the potential of natural resources for fisheries.  One of the organisms that has an important role here is phytoplankton. This study aims to analyze spatially and temporally the composition of phytoplankton abundance as fish food sources in Pabean Bay waters, West Java. Phytoplankton and physics-chemical parameters were taken monthly samples (June 2016-March 2017). Data analysis included the composition and abundance of phytoplankton, one-way variance analysis based on time and zone, the relation of physics-chemical parameters of aquatic to phytoplankton abundance, and phytoplankton used by fish as food. The abundance of phytoplankton differs on a monthly basis, but is not different in each zone. The phytoplankton found in the Pabean Bay is dominated by the Bacillariophyceae class. The dominant type of phytoplankton feeds from some of the captured fishes is Nitzschia and Pleurosigma from the Bacillariophyceae class.
