Abstract

The development of the clothes washing or laundry service industry continues to develop in residential areas increasing every year. This increases the amount of waste generated. So that it has a direct impact on the environment if it is not properly managed. Many contaminants are contained in laundry waste, including surfactants and phosphates which have the potential to have a damaging effect on aquatic ecosystems. In order to control pollution, waste water treatment is necessary. This study aims to eliminate the efficiency of the influence of variations in alum doses and variations in lime doses with the coagulation flocculation process in surfactant and phosphate levels only in washing waste.This study used coagulation and flocculation methods using 5% lime and 5% alum coagulants with alum doses of 5cc, 10cc, 15cc, 20cc and lime 2cc, 4cc, 6cc, 8cc. Fast stirring time of 1 minute at 100rpm, slow stirring 30 minutes at 20rpm with a settling time of 30 minutes. Based on the research analysis for the coagulation-flocculation treatment in laundry wastewater treatment using alum and lime coagulants is better at reducing the phosphate parameter having an efficiency value of 88.44% while the surfactant parameter has an efficiency value of 76.89%. Lime doses of 20cc alum and 8cc lime have a very significant effect on reducing surfactant and phosphate parameters below established quality standards and do not pollute the environment.

Abstract

Today liquid waste is very worrying because it easily mixes with moving water, for example in rivers. The use of detergents on a large scale is a form of environmental pollution originating from residential areas. The level of pollution will be even more dangerous if left too long. The impact that will be felt is the occurrence of pollution which is difficult to overcome and the disruption of the biota ecosystem in the waters and its surroundings. Therefore it is necessary to manage liquid waste, one of which is the phytoremediation system using the water hyacinth plant (Eichhornia crassipes). The purpose of this study was to determine the effect of water hyacinth with a phytoremediation system to reduce levels of phosphate compounds in laundry waste. The method applied is laboratory experimental which is an experiment conducted to be able to see the effect of the variables that are the object of research with a completely randomized design (CRD) for the experiment. The results obtained in this study were a decrease in phosphate levels of 0.607 mg/L (37.7%) at an interval of 12 days. Data analysis used a test of variance (ANOVA) with a significance value of 0.000, which means it is less than the sig value. < α = 0.05 that there is an influence on the variation in treatment time on the phosphate levels contained in household laundry waste.

Abstract

Clean water is a basic need for humans. Clean water that meets health requirement and is suitable for use as clean water can be determined by physical, chemical and biological water quality requirement determined by Minister of Health Regulation Number 32 of 2017 concering Environmental Health Quality Standards and Water Health Requirement for Sanitation, Swimming Pools, Solus Per Aqua and public baths which say the level of iron (Fe) in clean water is 1 mg/l. Rice husk is a by-product of the rice milling process which has been a waste that is rarely used and has the potential as an adsorbent for iron (Fe) levels. Ini this study, rice husks were prepared with two treaments without activation and with 30% NaOH activation after baing heated in a furnace at 400oC for 1 hour. The adsorbent was then tasted with groundwater containing high levels of iron (Fe) with an adsorbent weight of 5 grams, where the adsoption process was carried ot with contact time, namely 2 hours and 4 hours. The optimum adsorption process was obtained at contact time of 4 hours and with an activation treatment with average percentage of 70,644%.

Abstract

Minyak jelantah merupakan minyak goreng yang telah digunakan untuk menggoreng secara berulang kali. Sebagian besar minyak jelantah biasanya sudah rusak dan kandungannya membahayakan bagi kesehatan. Dibutuhkan alternatif solusi permasalahan untuk mengolah limbah minyak jelantah dengan mudah, biaya yang murah serta cepat agar limbah yang sudah terolah aman saat dibuang ke lingkungan. Minyak jelantah dapat dimanfaatkan kembali (daur ulang) menjadi bahan lain yang tidak berbahaya bagi manusia maupun lingkungan. Salah satu alternatif produk adalah lilin. Tujuan program ini adalah pelatihan memanfaatkan limbah jelantah yang ada, dan diharapkan dapat mengurangi limbah minyak jelantah dengan memanfaatkannya menjadi olahan produk lilin yang inovatif. Program ini diharapkan dapat meningkatkan kesejahteraan masyarakat dan merangsang usaha berskala kecil dan menengah yang mampu menyerap pengangguran dan menggerakkan sektor rill masyarakat, selain menjadi solusi pengelolaan limbah minyak jelantah yang berpotensi mencemari lingkungan.
