Abstract

Kualitas air sungai di sekitar tambang batubara 100% atau 36 parameter air masih memenuhi baku mutu lingkungan air permukaan kelas II. Perlunya perhatian adanya beberapa parameter seperti tembaga, sulfida (H2S), kesadahan, phosphat dengan tingkat kekritisan 60-99% yang mendekati batas baku mutu lingkungan. Sungai Separi Besar, Nilai indeks pencemaran Sungai Separi Besar diperoleh sebesar 0,771, Sungai Separi Anak sebesar 0,712 dan Sungai Tanjakan Kecil sebesar 0,746 dengan kategori status mutu air sungai masih menenuhi baku mutu (kondisi baik). Nilai Indeks Kualitas Air untuk Indeks Kualitas Lingkungan Hidup untuk sungai di sekitar kawasan tambang secara umum termasuk dalam kriteria sangat baik

Abstract

His study aims to analyze the extent to which a mixture of wood waste and used newsprint can be used as raw material for making paper.This study used a completely randomized design with two replications. where the treatment given is a mixture composition between waste wood pulp and old newsprint pulp, each consisting of 0 : 100% (A), 30% 70% (B), 50% : 50% (C), 70% : 30% (D) and 100% : 0% (E) of oven-dry weight of pulp per sheet of paperThe physical properties of paper pulp tested in the form of tear index, tensile index, crack index and folding resistance significantly affect the composition of the mixture of wood waste and used newsprint.The value of tear index, tensile index and folding resistance tend to decrease with the increase in the percentage of used newsprint to the composition of the mixture, while the value of the crack index increases. Wood waste and used newsprint can be used as raw materials in pulp and paper manufacture, especially in the treatment of mixed composition C (50%:50%.)
