Abstract

Asap cair telah banyak digunakan sebagai bahan pengawet pada industri pangan dan sebagai penggumpal lateks pada industri perkebunan, oleh sebab itu pada penelitian ini dibuat asap cair. Asap cair dapat dibuat menggunakan bahan baku bambu. Penelitian yang dilakukan menggunakan seperangkat alat pirolisa dan kompor listrik sebagai pemanas. Tujuan dari penelitian yang dilakukan adalah untuk mengetahui pengaruh waktu pirolisa terhadap % yield dan kualitas asap cair bambu yang dihasilkan. Variasi waktu pirolisa yang digunakan yaitu 1, 2, 3, 4, dan 5 jam. Hasil penelitian menunjukkan bahwa semakin lama waktu pirolisa maka % yield yang dihasilkan semakin besar. Selain itu juga mempengaruhi kualitas asap cair karena semakin lama waktu pirolisa maka reaksi dekomposisi semakin sempurna. Waktu optimum untuk mendapatkan asap cair dengan % yield  terbesar adalah pada waktu 5 jam, didapat % yield 31,20 %, dengan density 1,0064 gr/mL, total fenol 0,4134 %, dan total asam 6,7872 %.

Abstract

Charcoal briquette is a smokeless fuel which is a type of solid fuel substances made flying low enough so that the smoke generated in the utilization of health care will not interfere with the user's own briquettes. In this study, charcoal briquettes made from bintaro waste fruit and betung bamboo using amylum adhesives. This study aims to obtain briquettes bioarang with the best quality by varying the carbonization temperature and composition of raw materials. The method used in this study is experiments or experimental methods. Variation of carbonization temperature used was 350 0C, 400 0C and 450 0C, with a ratio of raw material composition of bintaro fruit and betung bamboo 50%: 50%, 40%: 60%, and 30%: 70%. This briquette-making through several stages of the preparation of raw materials, the initial analysis, the making of briquette and final analysis. The results from this study that the composition of raw materials bintaro fruit and betung bamboo carbonization temperature of 400 C with Inherent Moisture valuesobtained for 2.13%, 2:66% ash, volatile matter content of 25.33%, 72% fixed carbon and calorific value 6775.6 cal / g. The authors conclude that the composition of the raw material of bintaro fruit and betung bamboo 50%: 50% obtained an optimum charcoal briquettes. In this case I suggest to do some research of fruit bintaro and coal in order to obtain a higher calorific value, so that the resulting charcoal briquettes have the best quality.

Abstract

The activities of textile industry is often pollute the surrounding environment. It also occurs in industrial of Palembang  Weaving Songket. It influences the acidity and colored of the water. To manage this condition, the colored wastewater using adsorbents that absorbed from tea dregs. This study aimed to determine the effect of tea dregs adsorbent for wastewater quality improvement Songket industry. The Method of treatment of wastewater is used Batch system, which the wastewater is placed in a container by adding the adsorbent from the dregs of tea.  The used of variable is the absorption time for 2 hours, 4 hours, and 6 hours, with the composition of adsorbent mass 5 gr, 10 gr, and 15 gr. Tea dregs that used in this study has the 19.26% of hemicellulose, 39.54% of cellulose and lignin 20%. It takes four hours for the research in order to obtain maximum results, with tea dregs adsorbent composition that produces a pH smaller than the initial waste 6, COD content of 89.41 gr / L, and 3.993 ppm color intensity. Therefore, absorbent from the dregs of tea is very useful for the development of the textile industry, especially for Songket industrials.
