Abstract

The study aims to determine the diversity of vegetation in the Green Open Space of the Gasing Industrial Area. The study was conducted from April to July 2017. The method of analysis used quadratic method with 2 plots at different location with three repetitions, quantitative data analysis was done on density value, dominance, frequency, important value and diversity index of each plant species. The results showed that vegetation consists of 16 tribes and 19 species, dominated by Pteridophyta and Spermatophyta. Value of vegetation diversity (2,24) and uniformity value 0,30. The higher number of the species, the higher diversity index of the species. Such characteristics are caused by environmental influences such as organic matter content and low pH and factors derived from human intervention. Keywords: Vegetation, Diversity, industrial area

Abstract

Research on the Morphological Diversity of Lansium domesticum Corr in South Sumatra aims to examine the morphological diversity of L. domesticum in South Sumatra. The research was conducted in April 2017 to June 2017. This research was conducted by means of exploration carried out in seven districts covering, East Ogan Komering Ulu District, South Ogan Komering Ulu District, Ogan Komering Ulu District, Musirawas District, Ogan Komering Ilir District, Muara Enim District and Musi Banyuasin District. Sampling was done using purposive sampling method. Observation of morphological diversity was done by characterization of morphology and analyzed by the descriptive method. The result of this research shows that in South Sumatera, there were two variants of L. domesticum namely L. domesticum variant duku and L. domesticum variant langsat. Morphological characters that distinguish between duku and langsat variants were found under canopy conditions, the presence of hair on top and bottom surfaces of leaves, fruit shape, fruit skin thickness, fruit taste, and the presence of sap on ripe fruit.

Abstract

Penelitian bertujuan untuk mengetahui keanekaragaman vegetasi di kawasan terbuka hijau industri Gasing. Penelitian dilakukan dari bulan April - Juli 2017. Metode analisis mengunakan metode kuadrat den-gan 2 plot pada lokasi yang berbeda dengan tiga kali pengulangan, analisa data kuantitatif dilakukan terhadap nilai kerapatan, dominasi, frekuensi, nilai penting dan indeks keanekaragaman masing-masing jenis tumbuhan. Hasil penelitian menunjukan bahwa vegetasi terdiri dari 16 suku dan 19 jenis, didominasi oleh Pteridophyta dan Spermatophyta. nilai keanekaragaman vegetasi sebesar (2,24) dan nilai keseragaman 0,30. Semakin ting-gi jumlah jenis maka semakin tinggi indeks keanekaragaman suatu jenis. Karakteristik yang demikian disebab-kan oleh pengaruh lingkungan yang dimiliki seperti kandungan bahan organik dan pH rendah serta faktor yang berasal campur tangan manusia.
