Abstract

ABSTRAKPenelitian ini dilaksanakan karena adanya fakta bahwa konversi lahan pertanian menjadi tambak ikan tidak dikelola dengan baik dan diduga bahwa hal tersebut mempengaruhi pada proses penurunan kualitas air tanah. Variabel penelitian adalah kualitas unconfined ground water sebagai variabel independen dan penggunaan lahan sebagai variabel dependen. Metode proporsional purposive sampling dipilih dalam penelitian ini dan data dianalisis dengan menggunakan hydrochemical types classification. Penelitian ini mengindikasikan bahwa terdapat perbedaan unconfined ground water, perubahan komposisi kimiawi air dan kualitas unconfined ground water dalam setiap penggunaan lahan sawah non irigasi dan tambak ikan. Perbedaan ini didasarkan pada dua tipe hydrochemical yaitu F2-(CaHCO3)2(+) dan MgCl2(-) yang masing-masing ditemukan pada penggunaan lahan tersebut. Hal ini berarti bahwa kondisi tersebut dipengaruhi oleh adanya intrusi air laut ke dalam tambak ikan yang ditunjukkan oleh sifat air laut. ABSTRACTThe research is carried out due to the fact that the conversation of agricultural land into fish pond are not well managed, and it is supposed that it will influence the deterioration of groundwater quality. The research variables include unconfined ground water quality taken as an independent variable and land uses as dependent variables. Proportional purposive sampling method was chosen and the data were be analyzed using hydrochemical types classification. This research indicates that there are the unconfinied groundwater distinction, hydrochemical composition changing and unconfined groundwater quality on each nonirrigated rice field and fish pond land uses. These distinctions are based on two hydrochemical types of F2-(CaHCO3)2(+) and MgCl2(-) which are found respectively on nonirrigated rice field and fish pond land uses. It means that there are affected by sea water instrusion into fish pond showed by sea water properties.

Abstract

ABSTRAKTujuan penelitian ini adalah meneliti pengelolaan tambak udang dan respons petani terhadap inovasi teknologi yang ramah lingkungan di wilayah pesisir di Kecamatan Tayu, Kabupaten Pati. Penelitian ini mengevaluasi teknologi budidaya udang dan menetapkan respons petani terhadap teknologi budidaya udang dengan sistem tandon berdasarkan pertimbangan lingkungan. Hasil penelitian menunjukkan bahwa pengelolaan tambak udang dengan sistem tandon mampu untuk meningkatkan kualitas air dan proudksi udang. Hasil analisis statistik menunjukkan bahwa teknologi tandon adalah signifikan, tetap, respon petani terhadap teknologi tandon adalah sedang (moderate). ABSTRACTThe objective of this research was to study the shrimps pond management and the response of farmers to shrimps pond technological innovation with environmental consideration in coastal area of Tayu District, Pati Regency. The research was aimed at evaluating shrimps culture technology, establishing the farmers response to the shrimps culture technological with “tendon” system based on environmental consideration. The results showed that the shrimps pond management with “tendon” system is able to improve to water quality and shrimp production. The statistical analysis showed that the shripms of technology “tendon” system was significant. However the response of farmers to this technology “tendon” system is moderate.
