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

Industrial liquid waste in liquid form resulting from tempe production can pollute the environment which is detrimental to the surrounding community. According to the World Health Organization (WHO), waste is the result of human activities that are useless, not used or something that is thrown into the environment. Tempe industrial wastewater is very disturbing to waters if it is not managed properly before being discharged into water bodies because this waste causes an unpleasant odor and triggers the growth of various pathogenic bacteria. If the waste is directly disposed of into the waters, in a relatively short time it will cause a foul odor from H2S gas or ammonia as a result of the crying of the organic waste. The existence of a decomposition process will cause an unpleasant odor (Wiryani Erry, 2012). The process of making tempeh in each of its stages uses an average of water for washing, soaking, and boiling the soybeans. This means that quite a lot of liquid waste is produced. This study aims to analyze the content of soybean liquid waste to reduce BOD levels to make it more environmentally friendly. With the aim of reducing BOD levels, this study will use the Pseudomonas Putida bacterium as a waste decomposer, bioreceptors and microelectrodes as practical BOD measuring devices. The sample used is boiled liquid waste from soybean skin in the process of making tempe at one of the tempe entrepreneurs near the Satya Negara University of Indonesia. The sample was then tested to see the content of DO, BOD, temperature, pH, TDS, and total bacteria. The results of research on soybean liquid waste showed that the content of BOD and TDS exceeded the quality standards set by the Regulation of the State Minister for the Environment 03 of 2010 concerning the Environment.

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

This study aims to determine and analyze the safety culture (knowledge, attitude towards regulations, personality, availability of equipment, training, and motivation) that affect the compliance with the use of Personal Protective Equipment (PPE) of workers at the Water Laboratory of PT Unilab Perdana, South Jakarta. The research method used is quantitative with an explanatory format. The population of this study were 17 workers in the water laboratory of PT Unilab Perdana, South Jakarta. The sampling technique is a saturated sample, that is, all members of the population are used as samples. The research sample was 17 workers in the water laboratory of PT Unilab Perdana, South Jakarta. The research data collection technique used a questionnaire on compliance with the use of PPE on workers as the dependent variable and knowledge, attitude towards regulations, personality, availability of equipment, training, motivation as independent variables. Data analysis used simple correlation regression, t test, and coefficient of determination. The results showed that safety culture had a positive and significant effect on compliance with the use of PPE. The results of the t-test for tcount are greater than ttable, namely 3.493 > 2.109 at = 0.05 and 2.898 at = 0.01. This means that the correlation coefficient of safety culture on compliance with the use of PPE is significant. The coefficient of determination of the influence of safety culture on compliance with the use of PPE is obtained from the R square value of 0.449. So 44.9% of the variance in safety culture can be explained by the variable of compliance with the use of PPE. From the results of hypothesis testing, the findings show that safety culture has a positive and significant effect on compliance with the use of PPE. This means, the higher the safety culture, the higher the compliance with the use of PPE. Based on these findings, it can be concluded, if you want to improve compliance with the use of PPE, then the safety culture needs to be improved as well.
