Abstract

Industri sarung tenun Samarinda menghasilkan limbah cair dari sisa pewarnaan benang, dengan konsentrasi warna limbah cair sebesar 2168 Pt.Co. Konsentrasi ini berpotensi mencemari lingkungan, sehingga perlu dilakukan dekolorisasi agar konsentrasi warna limbah cair industri sarung tenun Samarinda dapat memenuhi standar baku mutu warna limbah yaitu sebesar 50 Pt.Co. Dekolorisasi limbah cair industri sarung tenun Samarinda menggunakan adsorben cangkang kerang darah teraktivasi. Penelitian ini dilakukan untuk mengetahui pengaruh massa adsorben dan kecepatan pengadukan dalam menurunkan konsentrasi warna limbah cair industri sarung tenun Samarinda. Variabel berubah yang digunakan dalam penelitian ini adalah massa adsorben (0.1, 0.2, 0.3, 0.4, 0.5 g) dan kecepatan pengadukan (120, 150, 200 rpm). Sampel limbah cair sarung tenun Samarinda dimasukan ke dalam Erlenmeyer sebanyak 50 mL lalu menambahkan adsorben cangkang kerang darah teraktivasi berukuran 200 mesh, kemudian mengaduk dengan shaker selama 30 menit. Sampel limbah kemudian disaring dengan kertas saring Whattman-42 lalu menganalisa konsentrasi akhir warna sampel setelah proses adsorpsi dengan metode analisa SNI 06-6989.24-2005. Hasil penelitian menunjukan bahwa kondisi optimum adsorpsi warna limbah cair industri sarung tenun Samarinda adalah pada massa adsorben 0,5 g, dan kecepatan pengadukan 150 rpm, dengan konsentrasi warna akhir sebesar 33,14 Pt.Co atau %removal sebesar 98,47%.

Abstract

Biobriquettes are one of the alternative energy solid fuels that are the basic materials of a biomass mixture. The addition of the word bio to briquettes is due to the addition of biomass as a raw material. Peanut skin and hazelnut shell that is only wasted resulted in the accumulation of agricultural waste in the form of peanut skin and hazelnut shell. To overcome this, further research is needed to have added value. In this study, it aims to influence the effect of the comparison of the composition of raw materials of peanut skin charcoal and hazelnut shells against proximate values and heat values. This study used carbonization methods. From the results of the analysis obtained the highest heat value in the treatment E was 6006 Cal/gr. Briquette water content ranges from 4 - 5% and the lowest water content was obtained in treatment B which was 4.08%. The results of the analysis of ash levels ranged from 11 - 17% and obtained the lowest ash levels in treatment B, which was 11.92%.  Volatile matter results ranged from 26 - 28% and the lowest Volatile Matter level at D treatment was 26.57% and fixed carbon results ranged from 50 - 55% and the highest fixed carbon result was at 55.96%.Keywords: bean skin, hazelnut shell, biobriquette, proximate
