This industry produces liquid waste that is produced from the coloring process using De Congo Red which is an organic dye. Discussing the business of Samarinda's woven sarong industry discharges its waste directly into the Mahakam River around the house or weaving location which will cause a harmful impact on the environment. The main process in this research is adsorption with active bentonite to determine differences in activated bentonite particles in the adsorption process. The performance of the adsorption process through the parameters of BOD, COD, TSS and, pH of the liquid waste. The adsorption process was carried out by mixing active bentonite and Samarinda waste woven gloves with 0.25 grams: 1 mL. The mixture is then stirred for 1 hour at a rotational speed of 468 rpm. The size of the active bentonite was varied by 210, 230, 270, 310, 330, 370 and 400 mesh. The results of this study have proven ...

Kemampuannya beradaptasi di lingkungan tercemar penting dipelajari, untuk pemanfaatannya sebagai bioindikatorlogam berat. Pendekatan morfometrikdan ekofisiologi, dilakukan untuk mencapai tujuan tersebut.Peubah yang diamati meliputi sebaran ukuran panjang, bioakumulasi logam berat pada daging kerang,indeks daging Meat Yields (MY), dan pola pertumbuhan, yang dihubungkan dengan peubah fisika kimia perairan. Hasil penelitiandi Muara Bama Panimbang dan Teluk Banten Bojonegara, Provinsi Bantenmenunjukkan bahwa kolom air dan substrat perairan tercemar Pb, Cd, dan Hg melebihi ambang, namun A. antiquata mampu meregulasi metabolisme tubuhnya, sehingga lebih dari 50% sampel kerang memiliki indeks daging (MY) kategori sedang. Kandungan Pb, Cd, dan Hg pada daging kerang, kolom air, dan substrat di Bojonegara, hal ini terkait dengan rendahnya salinitas perairan dibandingkan di Panimbang.Ukuran panjang tubuh A. antiquata berkisar10,35-54,35mm, menunjukkanpertumbuhan populasi berjalan baik meskipun lingkungannya tercemar logam berat.Ukurantubuh sampel kerang di Bojonegara lebih besar dibandingkan di Panimbang, namun kedua populasi memiliki kesamaan pola pertumbuhan, yaitu alometri negatif.

In this article we report on a new high precision measurement of non-photonic electron mid-rapidity invariant yield, improved nuclear modification factor and v 2 in Au+Au collisions at √ s NN = 200 GeV. We also present measurements of mid-rapidity invariant yield at √ s NN = 62.4 and v 2 at √ s NN = 39 and 62.4 GeV.
