Abstract

Indonesia is one of the salt producing countries that use sea water as a source of raw materials, the quality of salt produced is influenced by the quality of sea water. The resulting average salt quality contains 85-90% NaCl. Those salt quality are still below of the Indonesian National Standard (SNI) for human salt’s consumption sodium chloride content is 94.7 % (dry base) and for industrial salt 98,5 %. The improvement of seawater salt quality can be done by several methods: leaching (hydro-extraction), re-crystallization without chemicals or with chemicals, and ion exchangers. In this study we studied the improvement the quality of seawater salt by hydro-extraction method. The objective of this research to improve the quality of seawater salt by hydro-extraction method. The hydro-extraction is a method to improve the quality of salt by washing with saturated salt solution, this method influence by size of salt (diameter), time of hydro-extraction, saturated salt solution concentration and recycle time of saturated salt solution. Based on the results of the research, the hydro-extraction method can produce salt with purity 99,34 % NaCl. The condition is achieved at 30/40 mesh salt size and the time of use of saturated salt solution 5 times.

Abstract

Precipitated silica is a silica product, containing silica, a white powder, a large enough porous and nano particle sized. The precipitated silica products are needed to support the operation of various types of industries such as automotive tire industry, rubber industry, cosmetics industry, electronics industry, agriculture and others. This precipitate silica can be produced by a chemical reaction process between the sodium silicate solution and various types of acids such as hydrochloric, sulfuric, acetate and other acids. In this study, the source of silica was obtained from a pumice while precipitation formation was carried out with the use of carbon dioxide gas (CO2). The sodium silicate solution was obtained by extracting the silica contained in a pumice with sodium hydroxide (NaOH) solution and heated to 100C for 1 hours. The carbon dioxide gas is injected into the aqueous solution of sodium silicate in a bubble column reactor and there is a reaction to form a precipitated silica. Based on research results found that the quality of precipitated silica has a quality: white colors, 85-90% silica content, 12-20% aluminum oxide content and surface area 108-227 m2/g. The

Abstract

Potassium-Silica Humate Composite Gel or K-Si-Humate Composite Gel is a combined material of Potassium and Silica Humate derived from the extraction of raw materials for geothermal sludge and peat soil. This material is a multipurpose material, which can be used to improve soil aeration and as a fertilizer that can fertilize the soil because it contains humic acid. The purpose of this study was to examine the effect of cellulose content on the characteristics of the Potassium Silica-Humate composite gel. The manufacture of K-Si-Humate Composite Gel in this research by extracting potassium and silica from geothermal sludge and humic acid from peat soil, then the process of filtration and gel formation. The variable used is the addition of carboxymethyl cellulose content, namely Carboxy Methyl Cellulose (CMC). The best results from this study showed that with the addition of CMC, the highest silica content was 15.85%, and the highest potassium content was 89.88%.

Abstract

The bio briquette is a type of briquette that is derived from agricultural waste since it is intentionally produced using biomass charcoal. The processing of agricultural waste, such as mushroom planting material, into bio briquettes is characterized by its low cost. When bio briquettes undergo appropriate and accurate processing, they can yield briquettes of superior quality. The primary objective of this research endeavor was to generate a biobriquette using an agricultural byproduct derived from mushroom farming, while concurrently assessing the distinct attributes and properties of said biobriquette. The research utilized a total of 400 grams of waste from mushroom culture materials, together with an adhesive composed of 40 grams of starch. The briquette dough is subsequently extruded in a cylindrical shape. Subsequently, the mold briquettes are subjected to a heating process at a temperature of 80°C for 5 hours, to decrease the moisture content. The outcome of the smoke test indicates that the emission of smoke will cease after 75 seconds. In the conducted Combustion of Speed Test, the obtained findings indicate a combustion rate of 0.425 grams per minute, using an initial sample weight of 5.8 grams. The ash content yielded a reading of 10.6%.
