Latar belakang: Industri batik dapat menyebabkan pencemaran lingkungan apabila limbahnya dibuang ke sungai tanpa proses pengolahan. Limbah cair batik yang dihasilkan dari proses pewarnaan mengandung kromium. Kromium memiliki sifat karsinogenik dan nonbiodegradabel yang berdampak buruk bagi lingkungan dan kesehatan. Penelitian ini bertujuan untuk mendeskripsikan kondisi fisik air Sungai Kreongan dan ikan nila, serta mengetahui kandungan Cr dalam daging ikan nila.Metode: Penelitian ini menggunakan metode deskriptif. Tempat penelitian berada di Sungai Kreongan. Sampel ikan nila diambil dari 4 titik sebanyak 8 ekor dengan teknik purposive sampling. Jumlah sampel responden 89 orang dengan teknik random sampling. Data yang diperoleh diolah dengan SPSS kemudian dianalisis secara deskriptif dalam bentuk tabel yang dinarasikanHasil: Berdasarkan hasil observasi kondisi fisik air sungai kreongan titik 1 dan 4 tidak berwarna, tidak berasa dan tidak berbau. Titik 2 berwarna merah, memiliki rasa asin dan tidak berbau. Titik 3 berwarna kuning, tidak berasa dan tidak berbau. Kandungan kromium ikan sampel 1 yakni 1,6 ppm, sampel 2 yakni 2,9 ppm, sampel 3 yakni 1,9 ppm dan sampel 4 yakni 2,7 ppm. Kondisi fisik ikan sampel 2 memiliki ukuran tubuh tidak proporsional, filament insang berwarna merah pucat dan kondisinya geripis, sirip ekor geripis, mata cekung serta tubuh berwarna pucat. Ikan sampel 1, 3, dan 4 memiliki kondisi fisik sama yakni ukuran tubuh proporsional, filament insang berwarna merah, sirip ekor geripis, mata jernih dan tubuh berwarna hitamSimpulan: Dampak pembuangan limbah batik x pada titik 2 menyebabkan kondisi fisik air sungai berubah, menyebabkan akumulasi kromium tertinggi pada ikan nila dan merusak kondisi fisik ikannya.  ABSTRACTTitle: Physical Conditions of River Water and The Assessment of Contained Chromium Metal in Tilapia (O. niloticus) (Study at Kreongan River around Batik X Industry, Patrang District, Jember Regency.Background: Batik industry can cause environmental pollution, if the waste discharged into the river without processing. Batik liquid waste resulting from coloring process contains of chromium. Chromium have a carcinogenic and non-biodegradable characteristic that have a negative impact to environment and health. The aims are to describe the physical condition of river water and tilapia organs, and measure chromium value on tilapia’s body.Method: This research use a descriptive method, located on the Kreongan River. 8 Tilapia samples were taken from 4 sampling points using purposive sampling technique. This research have 89 respondents with random sampling technique. The data processed with SPSS then analyzed descriptively in the form of narrative table.Results: Based on the observation results at sampling point 1 and 4 the water have colorless, un-smell and didn’t have a taste. At point 2, the water have red color, salty and un-smell. At point 3, the water have light yellow color, un-taste and un-smell. The chromium content at fish sample 1 is 1.6 ppm, sample 2 is 2.9 ppm, sample 3 is 1.9 ppm and sample 4 is 2.7 ppm. Physical conditions of fish sample 2 are have disproportional body, the gill filaments was pale red and sparsed, one of the fins were flaky, sunken eyes and pale body. While the fish sample 1,3 and 4 have proportional body, red gill filament, one of the fins were flaky, clear eyes and black body.Conclusion: The impact of batik x waste at point 2 are cause the physical condition of the river, causing the highest chromium accumulation in tilapia and damaging the physical condition of the fish.

Global warming is a global issue. Eco campus or green campus is the concepts to resolve the environmental problems. The aim of this research is to analyze how eco is your campus observed from knowledge and students' perception on environmental sustainability education. The methods of this research are cross sectional study and analytic observational. The total of respondents is 160 students who randomly chosen. Respondents have interviewed about their perspectives on environmental sustainability education especially the eco campus concept. The result of this research showed that 134 respondents (83,75%) had known about the information of the eco campus. There were 77 respondents (48,1%) have the negative attitude, 43 respondents (26.9%) have the positive attitude and 40 respondents (25%) have the neutral attitude about the eco campus. The data showed that 91 respondents have poor behavior toward eco campus concepts (56,9%), 65 respondents good enough (40,6%) and 4 respondents have very good behavior (2,5%). The development of sustainable environment should be educated continuously to the higher students to meet the eco campus sustainability to reduce the global warming.

The level of meat production from purebred chickens in East Java Province from 2009 to 2019 reached 510,535.29 tons. The existence of heavy metal contamination in chickens are dangerous for human health due to the lack of good facilities and infrastructure on broiler farms including land and locations that must be environmentally friendly, and when rearing chickens in paying attention to the needs of water and feed for broiler chickens that are not polluted by heavy metals. The objective of this study was to describe the levels of heavy metals in chicken meat at X Chicken Farm in Kertosari Village, Pakusari District, Jember Regency. This research was a type of descriptive research. The subjects of this study were 20 samples of broiler chicken, well water, and 4 respondents. The sampling technique used purposive sampling. Data analysis used descriptive to describe the use of chicken feed, sources of drinking water, and the presence of heavy metal levels of Pb and Cd in chicken. The result indicate that as many as 20 samples of chicken meat contained levels of heavy metals Pb and Cd below the quality standard values according to Indonesian Nasional Standard (SNI) 7387:2009), namely (pb 0.3/kg) and (Cd <0.0200) while for water drinking water used comes from drilled wells containing Pb 0.001 mg/l and Cd 0.001 mg/l..
