Abstrak budidaya udang vannamei (litopenaeus vannamei) memerlukan kondisi lingkungan yang optimal, khususnya kualitas air, untuk mendukung produktivitas yang tinggi dan berkelanjutan. kecamatan simpang mamplam memiliki potensi pengembangan tambak udang, namun tingkat kesesuaian lahannya berdasarkan kondisi kualitas air belum terpetakan secara spasial. penelitian ini bertujuan untuk memetakan zonasi kesesuaian lahan tambak udang vannamei di kecamatan simpang mamplam berdasarkan parameter kualitas air menggunakan metode skoring dan overlay spasial. parameter yang dianalisis meliputi suhu, salinitas, ph, oksigen terlarut (do), amonia (nh₃), nitrit (no₂), dan total padatan tersuspensi (tss). setiap parameter diberi skor 1–4 (tidak sesuai, sesuai bersyarat, sesuai, dan sangat sesuai) berdasarkan kriteria kesesuaian budidaya, kemudian diintegrasikan menggunakan sistem informasi geografis (sig) untuk menghasilkan peta zonasi kesesuaian lahan. hasil menunjukkan bahwa 18,75% lokasi tergolong sangat sesuai (s1), 56,25% sesuai (s2), 12,5% sesuai bersyarat (s3), dan 12,5% tidak sesuai (n). parameter kualitas air yang menjadi faktor pembatas utama adalah salinitas serta senyawa nitrogen (amonia dan nitrit). pemetaan zonasi berbasis kualitas air ini menegaskan pentingnya pengelolaan tambak secara spasial dan berbasis lingkungan guna mendukung pengembangan budidaya udang vannamei yang berkelanjutan, serta dapat dijadikan acuan perencanaan tambak di wilayah pesisir lainnya. kata kunci: peta zonasi, udang vannamei, kualitas air, sig, simpang mamplam.

ABSTRACT Cultivation shrimp vannamei (Litopenaeus vannamei) requires condition optimal environment, especially water quality, for support high and sustainable productivity. District intersection Mamplam own potential development pond shrimp, however level suitability the land based on condition water quality is not yet mapped in a way spatial research This aim For map zoning suitability land pond shrimp vannamei in the District intersection Mamplam based on water quality parameters using method scoring and spatial overlay. Parameters analyzed covering temperature, salinity, pH, oxygen dissolved solids (DO), ammonia (NH₃), nitrite (NO₂), and total solids suspended solids (TSS). Each parameter is assigned a score 1 – 4 (no appropriate, appropriate conditional, appropriate, and very appropriate) based on criteria suitability cultivation, then integrated use System Information Geographic Information System (GIS) for produce map zoning suitability land. The results show that 18.75% of locations classified as very appropriate (S1), 56.25% appropriate (S2), 12.5% appropriate conditional (S3), and 12.5% not according to (N). Water quality parameters that are factor barrier main is salinity as well as nitrogen compounds (ammonia and nitrite). Mapping zoning based this water quality confirm importance management pond in a way spatial and based environment use support development cultivation shrimp sustainable vannamei, as well as can made into reference planning ponds in coastal areas other.
