Abstract

The purpose of this study was to determine the content of the Sarang Semut extractive in various parts of the plant and weight.  Sarang Semut are use in the study is that weight from 0-0,9 Kg; 1-1,9 Kg; 2-2,9 Kg; 3,-3,9 Kg; 4-4,9 Kg; 5-5,9 Kg; 6-6,9 Kg; 7-7,9 Kg and taken of three parts of the plant are: base, middle and end of the plant.  Analysis of data using Completely Randomized Design (CRD) 8 x 3 factorial with three replications.  The result of research on cold water extraction reflects differences in average levels of extractives in each treatment.  On the weight of 5-5,9 kg extractives levels average growth of 34,72% and that is the lowest extraction levels.  Highest extractive content of 40,56% of the weight from 0-0,9 kg. Difference in differences in average levels of extrative produce by 5,84%.  Average levels of extractives obtained by extraction of cold water which is at the base of the highest (38,83%) followed by the tip (37,74%) then the middle (35,52%). The result of research on hot water extraction showed that extraction levels are highest in the treatment of 7-7,9 kg (44%) and the smallest in treatment 4-4,9 kg (37,78%).  Difference in difference of 6,62%.  Hot water extraction to produce more levels of extraction from the cold water extraction.  This relates to the nature of the extractive substances are more soluble at high temperatures.  Extractive substances more easly  dissolved and more soluble in hot water extraction than cold water extraction.Key Words :   sarang semut (Myrmecodia sp), cold water extraction, hot water extraction, extractive

Abstract

This study aims to analyze the quality of charcoal briquettes produced from a mixture of kolang-kaling processing waste and alaban wood charcoal processing waste. The parameters assessed include moisture content, density, ash content, volatile matter, fixed carbon, and calorific value. The research method involved sample preparation and characterization of biobriquettes using the Indonesian National Standard (SNI) 06-3730-1995, which includes tests for moisture content, density, ash content, volatile matter, fixed carbon, and calorific value. The carbonization process was conducted using a simple drum kiln, and the briquettes were molded using 10% tapioca starch as a binder. Five composition treatments were applied: (A) 100% kolang-kaling processing waste charcoal; (B) 75% kolang-kaling processing waste charcoal + 25% alaban wood charcoal; (C) 50% kolang-kaling processing waste charcoal + 50% alaban wood charcoal; (D) 25% kolang-kaling processing waste charcoal + 75% alaban wood charcoal; (E) 100% alaban wood charcoal. Each treatment was replicated three times. The briquettes were shaped using a manual press mold. The results showed that the briquettes had physical characteristics with a moisture content ranging from 5.490% to 11.641% and a density between 0.835–1.070 g/cm³. The chemical characteristics included an ash content of 1.497%–16.197%, volatile matter of 40.593%–47.177%, and a calorific value between 3,781.69–5,708.92 cal/g.
