Abstract

Proses pembuatan briket batubara melalui beberapa tahapan yaitu proses penghancuran batubara, pencampuran serbuk batubara dengan tapioca sebagai perekat, dan pencetakan briket batubara. Pada umumnya pengoperasian mesin pencetak briket batubara masih secara manual dimana operator menarik tuas ke bawah dengao tangan atau diinjak dengan kaki. Karena kwalitas hasil pencetakan yang kurang, maka penulis berinsiatif untuk memperbaiki kinerja alat tersebut. Perbaikan alat ini adalah dengan melakukan perhitungan terhadap gaya penekanan, membuat rangka yang lebih ekonomis, memperbaiki cetakan dengan sekali cetak menghasilkan 7 buah briket dengan berat @ 30gram, menambahkan fixture, dan memperbaiki sistem kerja dengan menggunakan sistem hidraulik. Dari hasil perhitungan didapatkan gaya tekan untuk mencetak briket batubara sebesar 25223,9 N, dengan spesifikasi silinder aktuator sebagai berikut :Dpiston = 0,080 m, Drod = 0,025 m, Stroke = 0,060 m, Tekanan maksimum = 98 bar. Setelah itu didapatkan tekanan perencanaan pada silinder sebesar 5,8x10pangkat 5 N/m , kapasitas pompa 2,81x10pangkat -5 m3/detik dan daya motor 225 Watt.

The process of coal briquette through several phases. smashing the coal, coal dust mixing with tapioca as adhesive, and printing briquette coal. In general, the operation of the machine is still printing briquette coal operator manually where the operators pull down the lever with the hand or press it with foot. Because the quality of printing results that are less, the author bas some initiatives to improve the performance of these tools. Improvements to this tool is to make the calculation of the force of pressure, to create the framework more economical, to improve the printing of briquette, which once printing can produce 7 briquettes with each briquette have 30gram of weight, add the fixture, and improve the performance with using a hydraulics system. Results that obtained from the calculation of the force of pressure to print briquette of coal which have 25,223.9 N, with the specification of cylinder actuator as follows: Dpiston = 0.08 m, 0.025 m = Drod, Stroke = 0.06 m, maximum pressure = 98 bar. After that, was found that the pressure on the planning of cylinder which have 5,8x10pangkat5 N/m2 , capacity of pumps 2,81x10pangkat -5 m3/s and 225 Watt motor power.
