Anisa Safira. 26020117140058. Evaluasi Kesesuian Lahan Tambak Udang
Vannamei (Litopenaeus vannamei) Berbasis Sistem Informasi Geografis di
Kecamatan Kramat, Kabupaten Tegal. (Lestari Lakhsmi Widowati dan Sarjito)
Kecamatan Kramat merupakan salah satu dari tiga kecamatan di Kabupaten
Tegal yang memiliki area tambak terluas dan berpotensi dalam pengembangan
budidaya udang vannamei (Litopenaeus vannamei). Hasil produksi udang
vannamei tertinggi ada pada kecamatan lain, maka dari itu perlu dilakukan evaluasi
kesesuaian lahan tambak udang vannamei (Litopenaeus vannamei) untuk dapat
mengetahui kelayakan tambak udang vannamei dan pendugaan potensi produksi
udang vannamei dengan berdasarkan nilai oksigen terlarut. Proses pemilihan lokasi
budidaya yang tepat akan mempengaruhi hasil produksi kegiatan budidaya dan
pengembangan usaha budidaya tambak menjadi lebih baik. Metode yang digunakan
dalam penelitian ini adalah metode survei dan penentuan 10 titik sampling dengan
purposive sampling. Penelitian ini menggunakan Sistem Informasi Geografis (SIG)
dengan tujuan untuk mewakili lokasi area tambak pada Kecamatan Kramat.
Variabel kuualitas air yang diukur antara lain suhu, oksigen terlarut, pH, salinitas,
nitrat, fosfat, amonia, kecerahan, dan kedalaman yang dilakukan secara in situ dan
ex situ dan analisis produksi diukur berdasarkan kandungan oksigen terlarut.
Pengelolaan data dilakukan dengan menggunakan ArcGis 10.3 berdasarkan nilai
kualitas air yang menjadi acuan dalam menentukan lokasi yang sesuai untuk
budidaya udang. Hasil dari evaluasi kesesuaian lahan pada 10 titik sampling,
didapatkan luasan lahan budidaya udang vannamei termasuk kedalam kategori
kelas sesuai (S1) seluas 282,8 Ha dengan nilai skor 61-69. Hasil dari asumsi potensi
produksi udang vannamei berdasarkan nilai oksigen terlarut yaitu 8,6 ton/Ha.

ABSTRACT
Anisa Safira. 26020117140058. Evaluation of Vannamei Shrimp Ponds
(Litopenaeus vannamei) Based on Gepgraphical Information Systems in Kramat
District, Tegal Regency. (Lestari Lakhsmi Widiowati dan Sarjito)
Kramat sub-district is one of three sub-districts in Tegal Regency that has
the largest pond area and has the potential to develop vannamei shrimp
(Litopenaeus vannamei) aquaculture. The highest production of vannamei shrimp
is in other sub-districts, therefore it is necessary to evaluate the land suitability of
vannamei shrimp (Litopenaeus vannamei) ponds to determine the feasibility of
vannamei shrimp ponds and estimate the potential for vannamei shrimp production
based on dissolved oxygen values. The process of selecting the right cultivation
location will affect the production results of aquaculture activities and the
development of the aquaculture business for the better. The method used in this
study is a survey method and the determination of 10 sampling points with
purposive sampling. This study uses a Geographic Information System (GIS) to
represent the location of the pond area in the Kramat District. The water quality
variables measured included temperature, dissolved oxygen, pH, salinity, nitrate,
phosphate, ammonia, brightness, and depth which were carried out in situ and exsitu and production analysis was measured based on dissolved oxygen content.
Data management is carried out using ArcGIS 10.3 based on the value of water
quality which is the reference in determining the appropriate location for shrimp
farming. From the results of the evaluation of land suitability at 10 sampling points,
it was found that the area of vannamei shrimp cultivation was included in the
appropriate class category (S1) covering an area of 282.78 Ha with a score of 61-69. The results of the assumption of the potential for vannamei shrimp production
based on the dissolved oxygen value are 8,6 ton/Ha.
