Abstract

The study aims to determine the diversity of vegetation swamp ecosystems in the district of Tanjung Lago. The study was conducted from June to July 2011. Methods of analysis using squares method, quantitative data analysis conducted on the value of density, dominance, frequency, importance and diversity index of each type of plant. The results showed that the vegetation consists of 16 genuses and 21 species dominated by Pteridophyta and Spermatophyta. vegetation diversity value of (2.0680), the higher the number, the higher the index type of diversity of a kind. Such characteristics are caused by environmental influences owned as organic matter content and low pH and factors derived human intervention.

Oktaviani, et al. Vegetation Diversity of  Swamp in Tajung Lago District. JLSO 5(2):198-207. The study aims to determine the vegetation diversity of swamp ecosystems in the district of Tanjung Lago. The study was conducted from June to July 2011. Theanalysis is using squares method, and quantitative data analysis was conducted to measure the value of density, dominance, frequency, importance and diversity index of each type of plant. The results showed that the vegetation in the swamp consists of 16 genus and 21 species dominated by Pteridophyta and Spermatophyta. The value of vegetation diversity (2.0680), where the higher the number, the higher the index type of diversity of a kind. Such characteristics are caused by environmental influences such as organic matter content and low pH and factors derived by human intervention.

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.
