Abstract

Indonesia merupakan salah satu negara penghasil minyak sawit terbesar di dunia. Lebih dari setengah produksinya digunakan untuk kebutuhan dalam negeri dan sisanya diekspor. Produk turunan minyak sawit seperti Mono-Di Acyl Gliserol (MAG-DAG) mempunyai nilai ekonomi yang  tingg dan selama ini Indonesia masih mengimpornya. MAG- DAG dibuat dari senyawa gliserida yang banyak terdapat dalam bahan minyak atau lemak, seperti minyak kelapa sawit, dengan gliserol. Tujuan dari penelitian ini adalah Studi eksperimen produksi MAG-DAG dari minyak kelapa sawit pada suhu rendah (2000C) dengan reaktor batch skala laboratorium, dan mengetahui pengaruh variabel-variabel proses. Variabel berubah yang digunakan adalah suhu (70 oC, 90 oC, dan 110 oC), rasio gliserol/CPO (3, 4, dan 5), dan jumlah katalis (2% w, 3% w, dan 4% w). Sedangkan variabel tetapnya adalah berat total campuran reaksi 300 gram, kecepatan pengadukan 400 rpm, waktu 4 jam dan jumlah pelarut 20 ml/10 gram CPO. Dari hasil pengolahan data menggunakan program STATISTICA 6 diperoleh kondisi operasi optimum dicapai pada suhu sekitar 70-1000C, rasio gliserol/CPO sekitar 3,5-4,5 serta katalis pada kisaran 2,5-4% dengan konversi yang diperoleh sekitar 93-98%. Dengan adanya penambahan pelarut n-Butanol, reaksi dapat dijalankan pada suhu yang lebih rendah (di bawah 2000C) tanpa menurunkan konversi yang diperoleh.

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.

Abstract

Rice analogues are food products made from broken rice and/or any other carbohydrate sources to have similar texture and shape to those of rice. Corn flour can be used as a material to make the rice analogues because it has various amylose contents ranging from low, medium, and high so that it is possible to make the dough with different levels of amylose contents. High temperature extrusion process may change crystallinity of starch (crystal type of A to V and degree of crystallization). Changes in starch crystallinity may influence the physical properties of the rice analogue produced. This research aimed to assess the effect of flour amylose content and temperature of extrusion on the crystallinity and its impact on physical properties of rice analogue. High amylose corn starch and corn flour were mixed at certain ratios to obtain amylose contents of 16.99, 19.35, 21.72, and 24.09%. The dough was made by adding water to the mixed flour to have a moisture content of 40%. The dough was then extruded at temperatures of 70, 80, and 90°C using a twin screw extruder (BEX-DS-2256 Berto). The observed physical properties were type of crystal, degree of crystallinity, and hardness of the rice analogue. The results showed that the increase in extrusion temperatures from 70°C to 90°C increased the degree of crystallinity of the rice analogues from 7.98-11.49% to 12.15-13.61% and hardness from 4.06-4.91 kg to 4.74-8.20 kg. The increase in amylose contents (from 16.99% to 24.09%) enhanced the hardness of the rice analogue from 4.06-4.74 kg to 4.91-8.20 kg but did not show any significant effects on the degree of crystallinity. The degree of crystallinity is positively correlated with the hardness of rice analogue (correlation coefficient r=0.8).
