Abstract

This study aims to design a waste water treatment plant (WWTP) design; reference in making WWTP in another place; and do waste water treatment so it is not harmful to the surrounding environment. The location of the research in the Jakarta Transmart building, when this research was conducted in March to June 2018. The method used in the implementation of this study planning was the preparation of reports that included analysis of waste characteristics; review of literature studies that are used to study supporting theories during conducting problem analysis and discussion so that they can be considered into the planning of wastewater treatment institu- tions that will be carried out; collection of primary data and secondary data as material for study of wastewater treatment plant planning; and design, calculation of the dimensions of the wastewater treatment plant, technical specifications. Planning criteria, among others: processing efficiency and achieving target results in accordance with desired quality standards; land area needed; and care must be easy and simple. The results showed that the estimated discharge of water requirements found in the Transmart building was around 59.97 m³ / day, obtained from the calculation of the area of the building building to meet the needs of clean water needed per square meter. Aeration tank volume and Aeration 1 dimensions: 3.35 m long, 4.450 m wide, 2.550 m depth, 0.625 m free space height, 38.01 m³ volume. Aeration 2: 3.375 m long, 4.450 m wide, 2.550 m depth, 0.625 m free space height, 38.3 m³ volume. Total aeration body area = 76,315 m. Tub sedimentation: 3.35 m long, 2.850 m wide, 2.350 m depth, 0.90 m free space height, 38.3 m³ volume. Volume: 13.7. Tub Equalization: 2.625 m long, 5.975 m wide, 2.60 m depth, free space height 0.575 m, volume 40 m³. In the design of planning the installation of wastewater treatment systems for activated sludge should be added or further processing so that the water from processing can be reused and not wasted, such as filtration so that it can be used such as for washing vehicles, watering plants etc.

Abstract

This study aimed to analyze the LC50 value of metallic lead (Pb), chromium (Cr), and cobalt (Co)contained in the printing industry wastewater to Daphnia magna and analyze the relationship of these metals to the LC50 value. The measurement results konsnetrasi Pb and Cr do not exceed the quality standards established, but the metals Co exceeds quality standards. Toxicity of Pb, Cr, and Co were tested in static test using artificial solution of Pb, Cr, and Co in accordance with the concentration measured in the wastewater. Tests carried out consisted of two stages: a preliminary test and test base. Daphnia magna mortality data were analyzed using Probit method with the EPA program Probit Analysis Program Version 1.5. 24-hour LC50 value of Pb, Cr, and Co to Daphnia magna is 1.052% and the LC50 values of Pb, Cr, and Co are respectively 0.003 mg / l, 0.008 mg / l and 0.009 mg / l. All three metals have included the category of very toxic to Dahnia magna.

Abstract

The majority of RW 07 residents use groundwater daily. While flood and still water often happens and the inadequately of wastewater management are one of many problems RW 07 residents faced. The purpose of this research are to be able to identify sanitation condition in residential area and identify the bacteriological quality of groundwater in West Tebet Urban Village, and analyze the relationship between those variable. Total coliform test of groundwater procured from the local well using Most Probable Number (MPN) method. This research showed that the amount of total Coliform ranging from 3/ 100 ml to >240.000/ 100 ml and as much as 83% of groundwater in local wells have surpassed the amount Total Coliform standard which Indonesian Health Ministry regulated in No. 416/ Menkes/ IX/ 1990. Other than that, the result showed that there is no relation between septic tank and drainage distance also well depth to the amount of Total Coliform.

Abstract

This research is aim at determining relationship between conscientiousness, agreeableness, neuroticism, openness, and extraversion with citizenship behavior on managing the environment on Depok Jaya citizen. The method used was survey with a correlational study by involving 85 sample. There were six instruments which measured citizenship behavior on managing the environment (reliability 0,932), conscientiousness (reliability 0,943), agreeableness (reliability 0,931), neuroticism (reliability 0,893), openness (reliability 0,914), and extraversion (reliability 0,873). Data has been analyzed by two-way ANOVA. Research results revealed that there is positive and significant correlation among those variables, even though it has been controlled by second-order correlation, it is significant among them. Therefore, it could be concluded that if citizenship behavior on managing the environment would be improved, then citizen conscientiousness, agreeableness, neuroticism, openness, and extraversion should be taken into consideration.

Abstract

This study aims to analyze the differences in the length of fermented tempeh wastes using Pseudomonas sp bacteria in the manufacture of liquid fertilizer, nutrient content (Nitrogen) contained in tempeh liquid waste fermentation using Pseudomonas sp bacteria in the manufacture of liquid fertilizer, the number of bacteria in tempe liquid waste fermentation by using Pseudomonas sp bacteria in making liquid fertilizer. Quantitative methods, types of experimental research and observations with the aim of knowing the effect of fermentation time on the liquid fertilizer produced. The fermentation time used is, 0, 7 14. days while the volume of bacteria is 200 ml. The mathematical model of the factorial design trial design with 2 replications used is as follows, Mattjik and Sumertajaya (2000), conducted at the ITI Microbiology Laboratory Technical Implementation Unit on Jl. Raya PUSPITEK Serpong-Tangerang Selatan, from the beginning of sampling until the end of the check, starts from May to June 2018. The object of this research is the liquid waste of tempe derived from the results of boiling tempeh. In this study, the pH, nitrogen and total bacteria were seen before and after adding bacteria by fermentation. The results showed: (a) tempe liquid waste can be used as raw material for the manufacture of high-quality liquid organic fertilizer in accordance with the quality standard provisions (POC) with the addition of Pseudomonas sp in the fermentation method, (b) the increase in N content in this study was 1.52%, which is from the level of 0.56% pure urine after fermentation of N content to 2.08%.

Abstract

Water is a major requirement for the people of Indonesia. The source of water that is widely used is groundwater, ie water wells. Caused by increased human and industrial activity, well water can be contaminated with ferrous metals (Fe). To be able to make water as a source of clean water, processing needs to be done. This treatment process can be done by adsorption method. The material used can be utilized from the banana hump (Musa paradisiaca L.) as an adsorbent material. The objective of this study was to determine the decrease of ferro content in water by using dried banana paradisiaca L. (Musa paradisiaca L.). This research is experimental type. The cumulative decrease of ferro content (Fe) from the result of addition of banana bonggol with dose 0,08 gram, 0,1gram, 0,2 gram, 0,3 gram, and 0,4 gram respectively is equal to 16,16%, 17 , 96%, 32.9%, 51.5%, and 57.4%. The maximum result of the reaction is ferro content (Fe) in water decreased to 57,4% for dose 0,4 gram / 100 ml water for 30 minutes. In statistical results, there is significance value of p = 0,000 (á 0,05) or there is influence of various doses of banana stump in decreasing ferro content (Fe) in water.
