Oktaviani, Rulik (2016) Vegetasi Riparian Dan Persepsi Masyarakat Terhadap Konservasi Spesies Riparian Di Tepi Sungai Porong, Kabupaten Sidoarjo. Sarjana thesis, Universitas Brawijaya.
Abstract
Penelitian ini bertujuan untuk mendeskripsikan keanekaragaman spesies, spesies dominan, dan spesies yang berpotensi sebagai fitoremidiator, serta mengetahui persepsi masyarakat terhadap pelestarian dan pemanfaatan spesies riparian serta spesies yang berpotensi sebagai fitoremidiator pada vegetasi riparian di Tepi Sungai Porong, Kabupaten Sidoarjo. Analisis vegetasi riparian dilakukan di empat stasiun, yaitu area dekat Tambak (1), Pabrik (2), TPL Lapindo (3), dan Pemukiman (4) menggunakan metode kuadran. Tiap pengamatan diulang sebanyak tiga kali. Kajian persepsi masyarakat dilakukan dengan wawancara menggunakan rubrik wawancara yang terdiri dari empat variabel (pengetahuan, sikap, tindakan, dan persepsi). Data kualitatif dari hasil wawancara diubah menjadi kuantitatif dengan Skala Likert. Kualifikasi persepsi tiap variabel terdiri dari sangat baik, baik, cukup, buruk, sangat buruk. Hasil penelitian menunjukkan vegetasi riparian di area dekat Tambak mempunyai keanekaragaman spesies paling tinggi bila dibandingkan dengan area lainnya, ditunjukkan oleh indeks keanekaragaman spesies (1,03) dengan kategori sedang (1≤H’≤3). Area dekat Pabrik (0,95), Tempat Pembuangan Lumpur Lapindo (0,88), dan Pemukiman (0,95) mempunyai keanekaragaman spesies kategori rendah (H’ < 1). Turi, Tebu, dan Rumput Bermuda mendominasi area dekat Tambak. Pepaya, Pisang, dan Rumput Gegenjuran mendominasi area dekat Pabrik. Buah Anjang dan Rumput Bermuda mendominasi area dekat TPL Lapindo. Sementara Jati, Buah Anjang, dan Rumput Bermuda mendominasi area dekat Pemukiman. Masyarakat di area dekat Tambak mempunyai persepsi paling baik terhadap vegetasi riparian. Hal ini ditunjukkan oleh persentase responden paling besar pada aspek pengetahuan (80%) dan tindakan (72%) dengan kategori baik, serta aspek sikap (92%) dan persepsi (94%) dengan kategori sangat baik. Masyarakat di keempat area belum ada yang mengetahui peran vegetasi riparian sebagai fitoremediator. Namun, dengan persepsi yang baik di tiap area mampu meningkatkan upaya pelestarian vegetasi riparian yang berperan penting sebagai fitoremediasi di Daerah Aliran Sungai Porong.
English Abstract
The research aims to describe species diversity, dominant species, and species that are potentially as phytoremediation, also knowing public perception of conservation and utilization to riparian species and phytoremediation potential species at Porong Riverside, Sidoarjo District. Riparian vegetation analysis conducted in four station representing area near Fishpond (1st), Factory (2nd), Sludge Disposal Site of Lapindo (3rd), and Settlement (4th) by quadran method. Each treatment repeated three times. Assessment of public perception conducted by interview using interview rubric consist of four variables (knowledge, attitude, action, and perception). Qualitative data from interview result converted into quantitative using Lickert Scale. Qualification perception of each variables consist of very good, good, enough, bad, and very bad. The result of research showed that riparian vegetation in the area near Fishpond have highest species diversity compared with other areas, as demonstrated by species diversity index (1,03) with moderate category (1≤H’≤3). Area near Factory (0,95), Sludge Disposal Site of Lapindo (0,88), and Settlement (0,95) has low category in species diversity (H’<1). Vegetable Hummingbird, Sugarcane, and Bermuda Grass dominate in area near Fishpond. Papaya, Banana, and Kodo Millet dominate in area near Factory. Rough Cocklebur and Bermuda Grass dominate in area near Sludge Disposal Site of Lapindo. While Teak, Rough Cocklebur and Bermuda Grass dominate in area near Settlement. People in the area near Fishpond have most excellent perception of riparian vegetation. This is shown by highest percentage of responden in the aspect of knowledge (80%), and action (72%), with good category, as well as aspect of attitude (92%) and perception (94%) with very good category. In the fourth areas, no one know the role of riparian vegetation as phytoremediator. However, with good perception in each area is able to enhance the conservation of riparian vegetation which play an important role as phytoremediation in Porong Riverbank.
