Analysis of nutrient-carrying minerals from Tempe Lake sediment

Abstract

Abstract This study aims to determine the fertility of sediment in Tempe Lake from nutrient-carrying minerals. This study used transect method with sediment sampling from northern, southern, and eastern part of Tempe Lake. Analysis of minerals used X-Ray Diffractometer. The results show that nutrient-carrying minerals from eastern of Tempe Lake has biotite (35.6%), anorthite (7.1%), and olivine (6.8%), from northern has biotite (29.2%), olivine (20.7%) and pyroxene (9.1%), and from southern has pyroxene (88.6%), and amphibole (3.4%). The percentage of nutrient-carrying mineral content in the southern part of Tempe Lake is higher than the percentage of the total amount in the North and East parts, so that it is potentially used as ameliorant material for infertile soils.
