Residu DDT (Dichloro Diphenyl Trichloroethane) di lingkungan pesisir dapat masuk ke dalam tubuh Burung Cerek Jawa melalui perantara pakan alaminya. Residu DDT akan mengalami biomagnifikasi dan biotransformasi di dalam tubuh organisme. Tujuan dari penelitian ini adalah untuk mengetahui residu DDT di kawasan Pantai Trisik dan organ tubuh Burung Cerek Jawa, serta pengaruhnya terhadap hepar, intestinum, dan ren Burung Cerek Jawa. Lokasi yang digunakan untuk penelitian adalah kawasan hilir Sungai Progo dan pesisir Pantai Trisik. Pengambilan sampel dilakukan pada bulan Juni- Juli 2011. Metode pengambilan sampel lingkungan dilakukan secara langsung di lokasi. Pengambilan sampel burung dengan jaring kabut. Deteksi residu DDT di sampel lingkungan dengan kromatografi gas. Pengukuran residu DDT di pakan alami dan organ tubuh burung dengan spektrofotometer. Pembuatan preparat histologis hepar, intestinum, dan ren menggunakan metode paraffin (dengan pewarnaan Hematoxilin & Eosin dan Mallory Acid Fuchsin). Data kuantitatif diperoleh dari hasil pengukuran sampel lingkungan, pakan, dan organ tubuh Burung Cerek Jawa. Data kualitatif dibahas secara deskriptif. Hasil penelitian menunjukkan residu DDT terdeteksi di Sungai Progo, pesisir Pantai Trisik, pakan alami, dan organ tubuh Cerek Jawa telah melebihi ambang batas baku mutu lingkungan. Tingkatan efek kronis ditimbulkan oleh residu DDT terhadap struktur histologis hepar, intestinum, dan ren Cerek Jawa.

Residues of DDT (Dichloro Diphenyl Trichloroethane) in the coastal environment can get into the Bird's body through an intermediary Java Plover natural feed. Residues of DDT will experience biomagnification and biotransformation in the body organism. The purpose of this research was to determine residue of DDT in the Trisik Coast region, several organs of birds, and their impact on liver, intestine, and kidney Javan Plover. This research was located in Progo’s downstream and Trisik’s coastal. Sampling was conducted in June- July 2011. The method of environment and feed sampling done directly on site. The bird sampling using mist nets. Detection of residues DDT in environment samples by gas chromatography. Measurement of DDT residues in feed and organs of birds with spectrophotometer. Preparation of histological slide from liver, intestine, and kidney using paraffin method (with Hematoxylin & Eosin and Mallory Acid Fuchsin staining). Quantitative Data obtained from the measurement results of environment, feed, and organs of Javan Plover samples. Qualitative data analize by descriptively. The analysis showed DDT residues detected in area’s Progo downstream, Trisik coast, natural feed and Javan plover’s organ exceeds the threshold environmental quality standards. Analysis shows chronic effects posed by DDT residue on the histological structure of liver, intestine, and kidney Javan Plover.
