“…Evaluasi kesesuaian lahan/ perairan sangat penting dilakukan karena memiliki sifat fisik, sosial, ekonomi, dan geografi yang bervariasi atau lahan/perairan diciptakan tidak sama (Rossiter, 1996). Lahan/perairan memiliki karakteristik yang juga dapat berbeda antara yang satu dengan lainnya.…”

ABSTRAKKabupaten Kepulauan Sangihe dengan tiga pulau terdepannya dan panjang pantai 297 km memiliki potensi untuk pengembangan budidaya rumput laut (Kappaphycus alvarezii), tetapi belum tersedia data kondisi perairannya. Penelitian bertujuan untuk mengkaji karakteristik, kesesuaian, dan daya dukung perairan untuk budidaya rumput laut di kawasan pesisir Kabupaten Kepulauan Sangihe Provinsi Sulawesi Utara, Indonesia. Data karakteristik perairan yang dikumpulkan berupa pasang surut, kecepatan arus, arah arus, kedalaman, kecerahan, suhu, salinitas, oksigen terlarut, pH, nitrat, nitrit, nitrogen amonia total, fosfat, padatan tersuspensi total, bahan organik total, dan jenis substrat. Analisis dengan weighted linear combination dalam SIG dilakukan untuk penentuan kesesuaian perairan dan besarnya kapasitas perairan digunakan untuk penentuan daya dukung perairan. Hasil kajian menunjukkan bahwa karakteristik perairan Kabupaten Kepulauan Sangihe dapat mendukung usaha budidaya rumput laut, tetapi kedalaman perairan yang relatif dangkal dan adanya alur pelayaran yang menjadi faktor pembatas dalam kesesuaian lahan untuk budidaya rumput laut.

“…In the pedocentric viewpoint, the soil cover of natural areas is the main determinant of the formation of plant communities and their species composition (Rossiter, 1996;Kasparinskis and Nikodemus, 2012;Köster and Kõlli, 2013). In arable areas, soil cover composition is the main factor influencing the choice of suitable agricultural crops (Kõlli, 1994;Fisher et al, 2002).…”

The composition and properties of soil cover in three experimental areas in Estonia were analysed in terms of soil forming processes and land management practises. These areas were Jõgeva (JEA), Kuusiku (KEA) and Olustvere (OEA). Pedodiversity, humus forms and agrochemical status were analysed within seven arable land parcels. The soil cover of JEA was relatively homogenous. Dominant soil species were Cutanic Luvisols and Haplic Cambisols and the dominant soil texture of epipedons were slightly stony (pebbley) loams. The soil of KEA was much more heterogeneous, with five contrasting soil species in terms of soil genesis and four soil moisture states. The soil species in KEA were Mollic Gleysols, Haplic Cambisols, Gleyic Luvisols and Rendzic Cambisols (with relatively heterogeneous soils textures; from sands to loams). OEA was predominantly Stagnic Albeluvisol, with the topsoil texture consisting of sandy loam textures. In terms of soil species and properties JEA is representative of Central Estonian, OEA of South Estonian and KEA of North Estonian pedo-ecological conditions. These areas are generally representative of arable soils of the eastern part of the North European Plain. Soil cover is treated as a medium through which it is possible to improve the environmental status of an area. The 'environment protection value' (EPV) of soils were evaluated and detailed EPV categories were derived. Soils of JEA have high EPV due to neutral to slightly acid reaction, optimum humus contents, high cation exchange capacity, sufficient soil depth and the physical properties of subsoils are optimal. The EPV of KEA soil cover is less, due to high content of rock fragments in soil and and low biological activity within epipedons.

“…A GIS would help to improve the understanding of the processes of land evaluation and decision-making. It can improve the efficiency of data processing, can help to solve data integration problems and can support spatial analysis (Rossiter, 1996).…”
