Abstract

Danau Ranu Grati merupakan potensi sumber daya air alami yang ada di Kabupaten Pasuruan. Fungsi danau tersebut sebagai penampung air dan menopang berbagai kegiatan pemanfaatan di dalamnya seperti budidaya perikanan, penangkapan ikan dan pariwisata. Kegiatan tersebut merupakan tulang punggung para nelayan, pembudidaya keramba dan pengelola wisata alam danau sebagai sumber ekonomi masyarakat lokal. Namun kurangnya daya tarik wisata yang khas dari Danau Ranu Grati serta permasalahan penurunan kualitas air akibat kegiatan budidaya perikanan keramba, menyebabkan baik kerugian ekonomi maupun ekologis, sehingga seluruh kegiatan pemanfaatan danau tidak memperoleh hasil yang optimal. Oleh karena itu dibutuhkan upaya pengendalian kegiatan pemanfaatan melalui perumusan prinsip zonasi perairan beserta arahan pemanfaatan zona di Danau Ranu Grati. Tujuan penelitian adalah merumuskan prinsip zonasi perairan atas kegiatan pemanfaatan pada Danau Ranu Grati di Kabupaten Pasuruan. Tahap awal penelitian ini dimulai dengan menganalisis karakteristik perairan Danau Ranu Grati melalui teknik Spatial Linear Regression, Inverse Distance Weighted Interpolation dan Kriging Interpolation. Tahap selanjutnya yaitu menganalisis kegiatan pemanfaatan eksisting oleh stakeholder melalui teknik participatory mapping. Dari kedua tahap tersebut dilakukan perumusan zonasi perairan menggunakan teknik overlay dan analisis deskriptif. Hasil penelitian berupa zona dan arahan zona yang terbagi menjadi tujuh zona dan dua sub zona yang meliputi: 1) zona konservasi mutlak; 2) zona peralihan; 3) zona rehabilitasi; 4) zona sempadan, 5) zona perikanan ramah lingkungan, yang terdiri dari: a) sub zona penangkapan ikan dan b) sub zona perikanan budidaya; 6) zona wisata dan rekreasi; serta 7) zona permukiman nelayan. Luas total mencapai 224,89 hektar. Zonasi tersebut bermaksud untuk mengendalikan pemanfaatan ruang serta berfungsi menjaga kualitas dan karakteristik kawasan dengan meminimalisir kegiatan pemanfaatan lahan yang tidak sesuai dengan karakteristik asli kawasan. ================================================================= Ranu Grati Lake is a potential water resource in Kabupaten Pasuruan. It’s function are natural water reservoir and human activities support such as keramba fish farming, fishing and tourism activities. Those activities mentioned before are the subtantial jobs local fisherman, fish farmer and the tourism management as their economic resources. However, the lackness of Ranu Grati Lake’s tourist attractions and water quality degradation, that caused by fish farming bring about both economic and ecological loss. It means that the activities which are related to the lake, are unable to obtain optimum result. Therefore, a certain condition need to be carry out to control the activities by determining an aquatic zoning principle at Ranu Grati Lake. This research target is to determine the aquatic zoning principle of Ranu Grati Lake in Kabupaten Pasuruan. The first stage of this research starts from analyzing the Ranu Grati Lake’s water characteristic by Spatial Linear Regression, Inverse Distance Weighted and Kriging Interpolation techniques. The next stage is analyzing the existing stakeholders activities by participatory mapping. Then both stage’s result are analyzed to compose the aquatic zoning through spatial analysis overlay and descriptive analysis. This research obtains zones and their objections which divided into these seven zones and two sub zones: 1) absolute conservation zone; 2) transition zone; 3) rehabilitation zone; 4) lake’s border zone; 5) eco-friendly fishery include: a) sub zone of fisheries and subzone of keramba fish farming; 6) tourism and recreational zone; and 7) fisherman settlement. The total area reachs 224,89 hectares in extent. This zoning means to control the land utilization. And also to protect the water and land quality by pushing the land utilization which is not suitable with Ranu Grati Lake’s natural characteristic.
