Abstract

Along with the development of technology for utilizing peanut shells, which are usually only used as waste, it can also be used as activated charcoal which is widely used as an adsorbent for gas purification, metal absorbent, oil purification and water purification. Peanut shells (Arachis hypogea L) can also be used as activated charcoal by first removing the water content, ash content and iodine content, then activation using an activator. In this study, the activator used was a solution of NaOH and H2SO4. The purpose of the study was to determine whether peanut shells could be used as activated charcoal as an adsorbent of ion (Fe) levels in domestic waste. From the research that was conducted, peanut shells were used as raw material for making activated charcoal in determining the water content in heating 700 0C, the results were 11.62% and the heating ash content at 700 0C was 6.54%, then charcoal that had been heated heated and soaked using a solution of NaOH and H2SO4, with variations in the concentration of each 10% 20% and 30% solution then the best results obtained from activated charcoal in the H2SO4 activator with a concentration of 30% with the results of an ash content of 2.13% water content of 0.18% and an iodine content of 1055.30 (mg/g), the best activated charcoal in a 30% H2SO4 solution was then tested for ion (Fe) levels in domestic waste by triple testing and from the results in front the average was 91 .11%.

Abstract

This study was intended to determine the significance of changes in the concentration of SO2, NO2, and PM10 (particles <10 m) parameters in the free air on Car Free Day before the Pandemic Period and during the Pandemic Period, because the ambient air sampling point was carried out on Car Free Day during the time of the pandemic. This pandemic period is still the same as the period before the 2019 pandemic, namely in the Central Jakarta area around the highway health road area. The methodology used is to carry out direct measurements using an impinger tool to measure SO2 and NO2, and an HVAS tool to measure PM10 (particles <10 m). The time of the study was carried out in April - June 2021, where for data sampling, sampling would be carried out 2 times in one month between the second and third week of each month. The results of the study indicate that Car Free Day during the Pandemic period affects the decrease in pollutant concentration values for SO., NO., and PM10 parameters, where for the PM10 parameter it drops statistically significantly, and for SO., and NO. parameters it does not cause a statistically significant decrease. , where the data analysis was carried out by using the Paired T test with free samples at a significance of = 5%.

Abstract

The environment is said to be a polluted area, if there is a change in the standards of environmental quality standards which include, water, soil and air. This can happen by several factors, one of which is mining activities. Rice husk is a form of agricultural waste which is a "waste" from rice processing which has the potential as an adsorbent to absorb lead ions (Pb). In this study, rice husks were prepared with two treatments: non-activating and with 30% NaOH activation after being heated in a furnace at a temperature of 400 oC for 1 hour then the adsorbent was sieved with particles that passed through a 40 mesh sieve. The adsorbent was used to absorb 200 ml of Pb ions with an adsorbent weight of 5 grams, where the adsorption process was carried out in 2 contact times, 60 minutes and 120 minutes and tested in the laboratory. The adsorption process was obtained, the optimum was at a contact time of 120 minutes and the treatment was activated, with an average percentage of 94%.

Abstract

This study aims to analyze the relationship between knowledge about occupational health safety (OHS) and the behavior of users of personal protective equipment (PPE) with the radiation dose of workers. The research method used is quantitative. The population of this research is all radiation workers, totaling 12 workers at PT Incoray Nitrama. The sampling technique is a saturated sample, that is, all members of the population are used as samples. The research sample consisted of 12 radiation workers. Data analysis used simultaneous correlation regression, t test, and coefficient of determination. The results showed that, there was a negative and significant relationship between knowledge of OHS and behavior of PPE users together on radiation worker doses, because it was in the range of Fcount 6.043 > Ftable 4.26 at = 0.05. That is, the higher the knowledge of K3 and the behavior of PPE users, the lower the dose of radiation workers will be exposed to. The conclusion of the study, if exposure to radiation dose of workers is low, then factors such as knowledge of OHS and behavior of PPE users are increased. The coefficient of determination of OHS knowledge and behavior of PPE users together on radiation worker dose (R Square) is 0.573. This shows that 57.3% of the variance in radiation worker doses can be explained by knowledge of OHS and behavior of PPE users together, the remaining 42.7% is influenced by other factors outside the variables studied.

Abstract

The hospital in the Pulomas area has built 2 units of Waste Water Treatment Plant facilities with Anaerobic-Aerobic Biofilter and Extended Aeration systems. The performance of Waste Water Treatment Plants (IPAL) requires comprehensive maintenance and evaluation of Waste Water Treatment Plants (IPAL) so that the waste water treatment system works optimally and reaches the quality standards set by the Government. The results of measurements carried out in Oct-Nov 2021 at the old WWTP show that the pH complies with the quality standards of Minister of Environment and Forestry Regulation P.68 of 2016, namely between 6-9. Meanwhile, the discharge measurement results have exceeded the permitted limit in accordance with the Waste Water Disposal Permit set by DPMPTSP DKI Jakarta, namely 29 m3/day, but the IPAL capacity is still capable of processing the average discharge generated. At the new IPAL with the same testing time, the results of measurements carried out in October-November 2021 showed that the pH was in accordance with the quality standards of Minister of Environment and Forestry Regulation P.68 of 2016, namely between 6-9. Meanwhile, the discharge measurement results are still below the permitted limit in accordance with the Waste Water Disposal Permit set by DPMPTSP DKI Jakarta, namely 20 m3/day. In the Old IPAL the COD parameter exceeds the permitted limit in accordance with the Waste Water Disposal Permit set by the DPMPTSP DKI Jakarta, namely 2.90 kg/day, whereas in the new IPAL the evaluation results can be seen that there is no processing in the pramary treatment, namely a grease trap with processing efficiency. of 0%. From the results of the evaluation that has been carried out, it can be concluded that the average processing efficiency of the Old IPAL is 51.28%. When compared with the standard criteria for a WWTP with an Anaerobic-Aerobic Biofilter system with a processing efficiency level of 90-95%, the performance of the Old WWTP is less than optimal. Meanwhile, the average processing efficiency of the New IPAL is 46.74%. When compared with the standard criteria for a WWTP with an Extended Aeration system, the processing efficiency level is 85-87%, then the performance of the New WWTP is also less than optimal.
