PENGGUNAAN LAHAN BERBEDA DAN PENGARUHNYA TERHADAP C ORGANIK, BULK DENSITY, DAN KADAR AIR TANAH

Abstract

The research was conducted at the Botanical Gardens of Halu Oleo University and Mixed Gardens, taking place from January to March 2022. This research used a free survey method based on the land use of the Botanical Gardens and Mixed Gardens. Determination of C-Organic, bulk density and soil water content was carried out at the Laboratory of Nanoscience and Nanotechnology. The results of this study showed that different land uses varied, namely in the Botanical Gardens of Halu Oleo University C-Organik with low criteria (1.78-2.06%), Bulk Density namely (1.29-1.51 g cm⁻³), and Soil Water Content has criteria of low and very high (30.65-88.75%). Whereas in C-Organic Mixed Gardens, it is high (3.24%), Bulk Density is (1.18-1.55 g cm⁻³), and Water Content has high and very high criteria (22.62-39.45 %). The conclusion of this study is that the availability of C-Organic in different land uses between Halu Oleo University Botanical Gardens has low-medium criteria and Mixed Gardens has high criteria. Bulk density for different soil uses between Halu Oleo University Botanical Gardens has a value of 1.29-1.51 g cm ̄³ while in Mixed Gardens it has a value of 1.18-1.55 g cm ̄³. Water content in different soil uses between Halu Oleo University Botanical Garden soil has very high criteria. while in Mixed Gardens it has very high criteria.
