Abstract

This research examines the physical and chemical properties of the potential contamination of condenser cooling water (heat water) at the 2x7 MW West Sumbawa Steam Power Plant. The results showed that the hot water had met the predetermined quality standards, namely a pH of 8.21, a temperature of 38.50C and a content of free chlorine (Cl2) of 0.03 mg / L. There was an increase in sea water temperature in a radius of 17 meters east and west by 80C from 280C to 360C. Direct discharge of hot water has the potential to pollute the marine prawn environment around the 2x7 MW West Sumbawa PLTU. From the results of the study, it was found that the temperature of the hot water had met the specified quality standard, which was 40oC, but direct disposal caused the sea water temperature to rise, exceeding the set sea water temperature quality standard of 320C and the temperature increase should not be more than 20C from the temperature. at first.The status of sea water quality due to the entry of hot water is determined using a pollution index. From the calculation results obtained PIj of 1.125 at the sample point Outfall 2, meaning that the sea water conditions at a radius of 17 meters are lightly polluted. As a form of control and prevention of pollution due to the entry of high temperature hot water, continuous monitoring is necessary and it is necessary to create a mixing pool between sea water and hot water before the heat is discharged into the sea.

Abstract

Excessive usage of plastic has threatened not only environment but also human health if it is managed poorly. One of the solutions to manage plastic waste is through process of pyrolysis. A processing of plastic waste through pyrolysis is suggested where such process transform plastic waste into usable output of liquid, gas, and solid. Additionally, such process sorts out the liquid output into a number of characteristics thorugh faucet 1, faucet 2, and faucet 3. In this experiment, low density polytethylene (LDPE) and polyethylene terephtalate (PETE) were used. Process of pyrolysis were carried out at temperatures of 100 and 140 °C and at processing time of 30, 60, and 90 minutes. It was found that for both plastics, the best condition to obtain maximum output of liquid through condensation of steam/gas were 140 °C for 90 minutes. Although the production of large liquid output was effectively done by using PETE (574 gram) than that of LDPE (197 gram). The output of LDPE may effectively result in liquid with clear appearance through faucet 1. Output of solid from LDPE was more tough than that of PETE. Output of gases from LDPE exhibited better combustion as compared to PETE.

Abstract

There’s been research aimed at finding out the effects of age on the large absorbed dose of X-ray radiation received by the patient’s thorax examination. The observation data used to figure out the absorbed dose received by the patient is exposure factor consisting of tube voltage (kV), current (A), time (s), and distance (m) of patient from radiation source. The age range of patient obtained in this research is from 17 years until 48 years old, then it’s grouped by the age category set by Depkes. From the observation data of exposure factor and patients age, further do the test   using Oneway Anova statistical method test, by taking a significance level of a 0,05. The results from Oneway Anova statistic test is obtained FCalculate value is 1,532 amd sig is 0,211 with FTable value is 2,70 and sig is 0,05 therefore based on test criteria in statistic the early hypothesis (H0) is accepted. Presumably that the age is not affect on the large absorbed dose X-ray radiation received by the patient thorax eximination of range 17 years until 48 years old.
