Abstract

The derivation of alpha-pinene into various compound had been studied for many years. The transformation of pinene into camphene was carried out by hydrochlorination process. The process waas in fluenced by several conditions such as temperature, time of reaction and the atmospheric pressure. When the temperature and atmospheric pressure had been fixed, the time of hydrochlorination have a great effect. It was found that oversaturated condition of HCl gas reduced the camphene yield. The optimum time of hydrochlorination process was 30 minutes if 50 ml of alpha-pinene was bubble with HCl gas at the rate of 20 ml perminute on standard condition.

Abstract

Masalah dalam produksi nata de coco adalah keterbatasan air kelapa sebagai bahan baku. Kendala lain adalah bahwa air kelapa tidak dapat disimpan untuk waktu yang lama yang diakibatkan kerusakan nutrisi dalam air kelapa oleh mikroba. Penelitian ini bertujuan untuk menilai efek dari mikroba dan konsentrasi nutrisi pada produksi nata dengan menggunakan air tawar sebagai bahan baku. Produksi nata dengan menggunakan substrat air dilakukan dengan menambahkan gula sukrosa (gula) 10%, urea 0,5%, asam glacial asetat 2 % atau cuka dapur 25% sebanyak 16 ml / liter air kelapa. Nata pembuatan dilakukan melalui tahapan sebagai berikut: peremajaan kultur A. xylinum, preparasi substrat, preparasi starter, fermentasi, pemanenan produk, dan evaluasi hasil. Hasil yang diperoleh menunjukkan bahwa jenis air yang memberikan kualitas terbaik berasal dari air mineral dengan pendidihan terlebih dahulu. Hasil yang sama juga menunjukkan dari nata berasal dari air sumur. Kekurangan nata de coco yang dihasilkan dari air adalah rendemen yang lebih rendah dibandingkan dengan nata yang dihasilkan dari media air kelapa. Karakteristik lain dari nata yang dihasilkan dari air adalah elastisitas produk yang sama, kadar abu yang rendah, dan warna putih.
