Abstract

Electroplating industry is characterized in the metal plating process. This process occurs in the electroplating bath that contains a chemical solution. Before the coating process, the metal material to be coated should be washed first to remove the impurity attached. The metal materials that have been completely coated are then took from the bath and rinsed with water to clean the chemical solution attached at those materials. UD Citra Utama obtaines the water used for cleaning from the well in industry area around the company. Unfortunatley, the water well used is characterized by its relatively high salt content and turbid. Initial water analysis showed that those parameters are beyond the standard of water quality used for cleaning in electroplating industry. The use of this water has negative impact such as decreasing thw water quality, slows down the speed of coating process and eventually decreases the capacity and company income. To solve this problem, we have developed water treatment unit that treats the well water into pure water. The unit contains reverse osmosis (RO) membrane, pump, catridge prefilter and media filter. In addition, the unit is equipped with the accessories such as pressure gauge, flow meter and feed/product tank. The results of evaluation showed that water treatment unit can increase the product capacity 30% from 30 m2 to 39 m2 that correspond to income from Rp. 2000000,- to Rp 2600000,-. In addition, this unit can decrease the company omset from 5% to 0.5%. The water produced from this unit could meet the government role (Peraturan Menteri Kesehatan RI Nomor : 416/MENKES/IX/1990).

Abstract

Produksi jambu mete Indonesia mengalami peningkatan sebesar 6,2% dari tahun 1999 sampai 2003. Selain menghasilkan produk utama kacang mete yang bernilai ekonomi tinggi proses pemecahan biji mete juga menghasilkan limbah kulit biji yang belum dimanfaatkan secara optimal. Kulit biji mete mengandung minyak (Cashew Nut Shell Liquid/CNSL) sekitar 32-36%. Minyak ini mengandung senyawa phenol sehingga dapat dimanfaatkan sebagai sumber phenol alami dalam pembuatan resin phenol formaldehid, menggantikan phenol yang berasal dari minyak bumi yang cadangannya semakin menipis. Penelitian yang dilakukan bertujuan untuk mengetahui pengaruh variabel perbandingan reaktan dan suhu operasi terhadap resin yang dihasilkan dan mencari kondisi optimum reaksi polimerisasi phenol formaldehid dari CNSL serta kualitas coating yang dihasilkan. Pada proses reaksi phenol formaldehid variabel yang dipilih sebagai variabel berubah adalah  rasio Formaldehid/CNSL atau F/C (0.5, 0.75 dan 1) dan suhu operasi (70, 80 dan 80oC). Sedangkan lainnya merupakan variabel tetap yang meliputi volume 250 ml, katalis HCl(p)= 4 ml, kecepatan pengadukan 200 rpm, waktu operasi 90 menit, pH = 2 dan tekanan operasi 1 atm. Parameter yang diamati adalah kadar formaldehid bebas. Metode yang digunakan untuk merancang dan mengolah data hasil percobaan adalah RSM (Respon Surface Methodology). Variabel yang paling berpengaruh adalah rasio F/C dan kondisi optimum didapatkan pada rentang rasio F/C=0,65-0,85 dan rentang suhu 75-85oC dengan konversi 0,55. Kualitas resin terbaik untuk aplikasi coating diperoleh pada perbandingan reaktan F/C=0,75/1. Kata kunci : CNSL,  phenol formaldehid, coating
