Abstract

Salah satu yang menjadi perhatian dalam penelitian ini adalah mengenai penyediaan Green Ruang Terbuka (RTH) atau hutan kota di Sangatta. Ruang Terbuka Hijau (RTH) harus digunakan sebagai maskot kota untuk menampilkan kekayaan floristik hutan tropis, sehingga harus didukung oleh pengayaan spesies lokal. Penyediaan RTH di Sangatta sekarang harus didesak melihat tingginya pertumbuhan penduduk dan kebutuhan lahan. Selain itu, tingkat polusi juga tinggi, terutama debu, serta potensi banjir. RTH dapat berkontribusi sebagai daerah tangkapan air untuk menjaga sistem air terutama di kota Sengata dan sebagai zona penyangga untuk mengurangi dampak dari polusi udara. Kecukupan RTH atau hutan kota di Sangatta berdasarkan tingkat konsumsi bahan bakar (BBM), ternak dan kebutuhan oksigen adalah seluas 1,372.27 hektar. Kemudian, berdasarkan jumlah penduduk kota Sangatta untuk tahun 2012, sesuai kebutuhan RTH di Sengata seluas 23,2 hektar. Berdasarkan perhitungan tersebut, maka diperlukan RTH di Sengata, sebesar 1.395 hektar, atau sekitar 4,8% dari wilayah Kecamatan Sangatta Utara dan Selatan. Menurut peraturan yang ada luas RTH minimal 30% dari luas keseluruhan wilayah kotta. Sehingga berdasarkan pada perhitungan Sangatta masih harus menambah luasan RTH baik dalam bentuk Hutan Kota dan fungsi lain. Kota Sangatta harus segera menambah luasan RTH menginggat tingginya pertumbuhan penduduk. Selain itu RTH harus bisa mencapai 30% atau lebih dari kota luasan Sangatta, karena kota tersebut berdampingan dengan pertambangan batu bara.Kata kunci : hijau, ruang, kota

Abstract

Post-mining reclamation includes various activities of structuring, restoring, and improving environmental quality. Revegetation contains replanting activities that are part of post-mining reclamation. Several considerations are needed in determining the choice of plant species for revegetation activities. This study aims to determine the order of priority for the selection of revegetation plant species based on criteria and indicators of ecological value. The research location was in the revegetation area of PT. Adaro Site Tanjung, South Kalimantan. A total of 6 measurement plots (40mx25m) were made using purposive sampling method in determining the selected measurement plots. Each measurement plot was divided into 4 measurement sub plots to measure the number of species, number of individuals, diameter and height of revegetation plants. The indicator criteria used as an analytical tool contain 6 criteria and 8 indicators. The eight indicators are the contribution of the species diversity index, growth percent, number of individuals/ha, dominance, species authenticity, canopy cover, natural introduction of new plants, and the rate of weathering of litter. The revegetation plant species assessed were Akasia (Acacia mangium), Johar (Cassia siamea), and Sengon (Paraserianthes falcataria). Data were analyzed quantitatively through scoring against the total value of the indicators or categories made. The order of priority for revegetation plants is P.falcataria (score 24 = high score), Johar (score: 23 = high score), and Akacia (score: 19 = low score). Ecological feasibility indicator criteria developed in this study can be used as a model for the selection of species to be developed in post-coal mining revegetation area
