STUDI KELAYAKAN BUDIDAYA TAMBAK DI LAHAN PESISIR KABUPATEN PURWOREJO

ABSTRAKUdang vaname di Kabupaten Purworejo khususnya Kecamatan Grabag memiliki prospek pasar bagus, hal ini menjadikan budidaya tambak udang vaname menjadi peluang yang sangat besar. Seiring berjalannya kegiatan budidaya udang vaname, perlu diperhatikan aspek kelayakan lahan. Penelitian dilakukan dengan tujuan menganalisa kelayakan lahan budidaya tambak udang vaname (Litopenaeus vannamei) di lahan pesisir Kabupaten Purworejo. Penelitian ini difokuskan pada dua lokasi yaitu tambak pesisir desa Ketawangrejo dan Harjobinangun, Kecamatan Grabag Kabupaten Purworejo menggunakan analisis kelayakan lahan dengan metode scoring. Hasil penelitian menunjukkan bahwa kelangsungan hidup dan produksi tergolong cukup tinggi yaitu 90,16% dan 950 kg/0,10 ha untuk tambak pesisir desa Ketawangrejo, dan 81,00% dan 2.825 kg/0,21 ha untuk tambak pesisir desa Harjobinangun. Tingginya nilai kelangsungan hidup dan produksi yang diperoleh berkaitan dengan aspek bioteknis seperti lokasi dan konstruksi tambak, sarana dan prasarana serta sistem budidaya yang termasuk dalam kategori cukup sesuai (S2) baik. ABSTRACTShrimp vaname in Purworejo Regency, especially Grabag Subdistrict, has good market prospects, this makes the cultivation of vaname shrimp ponds an enormous opportunity.
