Abstract

Chemical laboratory liquid waste Environmental Pollution Control Techniques Cilacap State Polytechnic is liquid waste originating from practical or research activities of lecturers / students. Most of the waste contains organic and inorganic substances that are harmful to the environment. In the initial analysis the results of the wastewater content were in the form of lead less than 0.251 mg / L, Hardness 213.33 mg / L, TDS 4690 ppm, and pH 1.6. One parameter that needs to be addressed is TDS because dissolved solids can affect the O2 levels contained in the waters. In this research, a prototype of a waste processing tool was used to process the waste. In this research the method used is the process of coagulation, electrocoagulation and sedimentation in batch with a variation of residence time which affects the product. In addition, the filtration and adsorption process uses a continuous system, so that overall the tool uses a semi-batch system. In this study the chemicals used for processing were CaCO3 and citric acid. Then the adsorbent used is zeolite and activated charcoal as absorbent of dissolved solids. This waste treatment tool is considered quite effective in reducing TDS with a final result of 2950 ppm.

Abstract

Air pollution requires proper handling so that the impact can be reduced. Nipah fruit shell contains high cellulose and lignin so that carbon from nipah fruit shell needs to be implemented as an adsorbent to reduce the concentration of Hydrogen sulfide (H2S) gas produced from fish waste. The purpose of this study was to determine the characterization of carbon from nipah fruit shells as H2S gas absorbers with the effect of time variations of 10 minutes, 15 minutes and 20 minutes. The method of absorption of H2S absorption using iodine absorption with iodometric titration. The sampling process went through several stages, such as the carbonization process, carbon characterization process, and H2S gas adsorption using carbon that had been characterized by water content and iodine absorption. This research resulted in the production of carbon from nipa palm shell as an H2S gas absorber which has a water content characterization of 1.0651% and an iodine absorption capacity of 615.6105 mg/g so that it can adsorb H2S gas with an initial concentration of 64 ppm until it reaches the lowest concentration of 5.538 ppm.
