RINGKASAN
Seiring dengan perkembangan jaman, industri tekstil dan produk tekstil semakin bertambah. Pertambahan produk tekstil memicu naiknya hasil samping berupa limbah cair. Limbah cair tekstil mengandung logam berat yang berasal dari proses pewarnaan dan penyempurnaan tekstil, salah satunya adalah logam Cr dapat mencemari perairan sekitarnya dan meracuni organisme air yang hidup di lingkungan tersebut. Mengingat bahwa logam Cr yang terdapat dalam limbah cair tekstil dapat mengakibatkan kerusakan lingkungan, maka telah dilakukan penelitian tentang penyebaran logam Cr yang terdapat didalam air, sedimen, dan tumbuhan eceng gondok (Eichornia crassipes (Mart.) Solms), pada aliran limbah tekstil PT “X” Pekalongan. Tujuan penelitian ini adalah mengetahui kandungan Cr dalam tumbuhan eceng gondok, sedimen, dan air pada rona lingkungan yang berbeda; dan mengetahui kandungan Cr tertinggi yang terdapat pada rona lingkungan yang berbeda.
Penelitian dilakukan dengan metode survei. Sampel tumbuhan eceng gondok, sedimen, dan air diambil secara Purposive Sampling di empat rona lingkungan yaitu rona sebelum pembuangan limbah pabrik, rona pabrik, rona persawahan, dan rona perumahan. Hasil penelitian menunjukkan bahwa rona lingkungan sangat berpengaruh (F hitung > F.tabel 0,1%) terhadap penyebaran logam Cr dalam tumbuhan eceng godok, sedimen,dan air pada rona lingkungan yang berbeda dan kandungan logam Cr tertinggi dalam tumbuhan eceng gondok, sedimen, dan air terdapat pada rona lingkungan pembuangan limbah tekstil.
Kata Kunci: Penyebaran, Cr, eceng gondok (E. crassipes (Mart.) Solms), sedimen, air.

SUMMARY
As development time goes, textile industry and textile product are increasing. Increase textile products cause a rise in the form of liquid waste. Liquid textile waste contains heavy metals which is from the dyeing process and refinement of textiles, The one of those is Cr which can contaminate the surrounding waters and poison the aquatic organisms that live there. Cr metal can also cause ulcers in the nose, skin hyperpigmentation, skin cancer, and renal tubular necrosis indicated. As known that Cr contained in textile waste can cause environmetal damage so it has been done research on the spread of Cr contained in water, sediment, and water hyacinth plants (Eichornia crassipes (Mart.) Solms), at the textile waste stream PT "X" Pekalongan. The purpose of this study is to determine the content of Cr in water hyacinth plants, sediments, and water at different environmental setting; and determine the highest Cr that contained it.
The research is conducted by survey. Samples of water hyacinth plants, sediments, and water taken by purposive sampling in four environmental setting that before waste disposal, factory hue, hue rice fields, and housing hue. The observed variables are the levels of Cr on water hyacinth plants, sediments, and water in four environmental setting. The data obtained in the form of Cr levels in water hyacinth plants, sediments, and water described in any environmental setting then analyzed by ANOVA at the level of 95% and 99%, followed by the LSD test error rate of 5%. The results shows that the environmental setting really affects (F count> F.tabel 0.1%) in the spread of Cr in godok hyacinth plants, sediments, and water at different environmental setting; The highest Cr metal content in the water hyacinth plants, sediments, and water contained in the environmental setting of textile waste disposal.
