Abstract

Pada penelitian ini dipelajari tentang penambahan kalsium oksida, tetes tebu, dan serbuk gergaji sebagai perekat, bahan imbuhan, dan oksidator pada briket batubara melalui reaksi penetralan titrasi asam basa dengan indikator penolphtalein. Penambahan bahan-bahan tersebut dimaksudkan untuk mengurangi kandungan belerang dioksida pada briket batubara dan untuk mempercepat waktu pembakaran awalnya. Briket batubara dimasukkan bom kalorimeter dan diperoleh larutan H2S04. Kristal NaOH dilarutkan dalam air dan distandarisasi dengan HC1 standart. Larutan NaOH hasil standarisasi digunakan untuk menitrasi larutan H2S04. Hasil dari penelitian menunjukkan bahwa konsentrasi/kandungan belerang dioksida akan menurun bila ditambah dengan CaO dan serbuk gergaji. Dimana untuk briket batubara bentuk telor ini mengalami penurunan kadar belerang dari 9,53 % hingga 2,76 % dengan bahan imbuhan berupa kapur dengan tujuh komposisi berat yang berbeda. Akan tetapi komposisi yang tepat antara batubara-kapur diperoleh pada posisi 0,774 gram batubara dengan 0,015 gram kapur. Disamping itu waktu pembakaran awalnya mengalami penurunan dari 5 (lima) menit hingga 13 (tigabelas) menit. Pengukuran waktu pembakaran awal juga dilakukan dengan serbuk

The adding of calcium oxide, molasses and sawdust as adhesive, additional material, and oxidator on coal briquette by acid-base titration neutralization reaction with penolphtalein indicator have been studied. The adding of material mentioned above purposed to reduce sulphur dioxide content in coal briquette and to accelerate it’s combustion. Coal briquette must put into bomb calorimeter and we get H2SO4 solution. NaOH crystal dissolved in water and standardized by standart HC1. NaOH solution standardized result then need to titration H2S04 solution. The result of this study show that sulphur dioxide concentration /content decrease as CaO and sawdust adding. For egg-shape coal briquette, decreasing sulphur contentfrom 9,53 % to 2,76 % by various composition CaO adding. But, the right composition between coal briquette-calsium dioxide get on value 0,774 gram coal briquette with 0,015 gram CaO. And the ignition combustion time, decreasing from the five (5) to the thirteen (13) minutes, too. The measuring ignition combustion time also carried out with sawdust. Where, the ignition combustion time will increase as the increasing amount of sawdust from 0,05- 0,35 gram with ignition time 7,2-1,5 minutes. This is show that sawdust are important in increasing ignition combustion time. But, from the contents of S02, not too much influence the amount of sawdust.
