Abstract

Magetan society  rarely take advantage of the organic waste. So it is necessary to do research on composting. This study aims to determine the effectiveness of sewage treatmentusing cabbage and mango leaves as main material and activator used were cow dung, goatdung and EM4. This is a pre-experimental research. Data collected by the experiment, measured andobserved. 27 samples of 3 diferent-processes were 9 sample using cow manure activators, 9second sample using goat droppings activator and 9 third sample using activator EM4. Thedata were then analyzed by calculating the average weight reduction of waste.Analyses usingANOVA test. Based on the result of statistical test, it is known ρ sign 0,000 α (0,01) so that Hisaccepted or no difference to the effectiveness on variation activator mixture of cabbage andmango leaves as compost. The results showed that the use of cow dung activators weightdecreased 28.20%, temperature (27-37) ° C, pH (6.6 to 7), humidity (55-70)%. The use ofgoat dung activators weight down 40.90%, temperature (28-39) ° C, pH (6.7 to 7), humidity(65-75)%. The use of EM4 weight decreased 61%, temperature (27-40) ° C, pH (6.6 to 7),humidity (55-75)%. We recommend using EM4 activatorbecause the result is the best. Keep thetemperature and humidity so that the composting process is going well.

Abstract

Medical wastes need to be handled properly. The forefront of this efforts is the waste generationnode. The health worker who are responsible for waste generation are nurses at the nursingwards. The the nurses were in the forefront and determine the fate of the medical waste treatmentin a hospital. The purpose of this study is to reveal nurses’ behavior pertaining to the managementof medical waste.Data were collected through interviews and observation of the behavior of the nurses on themorning duty, than analyzed the data descriptively.Results showed that 64% of waste generation location has made efforts in the sorting of wastes,but all of them (100%) has not been doing well in stowage. It is not easy to understand, since75% of the nurses have good knowledge, but only 54% who carry out the disposal of medicalwaste properly. Therefore it is advisable to provide support to medical waste disposal facilities throughout the waste generating rooms and implementing reward and punishment system for those who should do so.

Abstract

Shift work affects the occurrence of physiological factors on workers especially night shift workers. Changes in working time from daylight to night resulted in physiological disorders.Workers can not be changed or workers circadian rhythms that are not able to adjust to changes in working time cause physiological disorders. Therefore, research on the effect of shift work on physiological factors plywood factory workers of PT. Admira rural districts Sukomoro Magetan 2015 Magetan district.This research is a descriptive study with the stratified random sampling design of 19 respondents.Based on the results of the study, 94.74% of respondents experienced a physiological disorder. Respondents who experienced a physiological disorder with symptoms of fatigue 75.93%.Male respondents who experience fatigue disorder 47.21%, 47.21% of sleep disorders, and gastrointestinal disorders 55.56%. Female respondents who experience fatigue disorder 38.89%, 27.78% of sleep disorders, and gastrointestinal disorders 27.78%. This indicates that respondents who experienced a physiological disorder that respondents can not be changed circadian rhythm,or the respondents were not able to adjust to the time change from daylight to night work. For that we need additional hour of rest and given special facilities to rest for the nightshift workers. It should also be noted the division of working time, rest periods, and the worker'sage, especially night shift workers to minimize the physiological effects of workers.

Abstract

The low porosity and permeability shale are nowadays known as self-resourcing reservoirs. In the unique organic shales, TOC has a signifi cant contribution to the elastic properties of rocks. TOC behaves like porosity to a density log and effects in decreasing density. To reduce the uncertainty due to TOC and mineral variability effect, a quantitative interpretation of shale reservoirs should be done properly to obtain the best image of shale systems. In this study, we built rock-physics templates (RPT) to esti mate seismic response by defi ning the relationship between total organic carbon (TOC) and effective elastic properties of shale reservoirs of a data set from South Sumatera Basin, Indonesia. RPT is carried out by incorporating the amount of organic matter into shale pore space as a solid-fi lling inclusion. Moreover, shale porosity is assumed to be fully water-saturated determined by the in-situ conditions. We have estimated the general distribution of pore geometry by investigating aspect ratio from the dataset. A solid background of shale from several different minerals is estimated by using effective medium theory. Properties of porous rocks for solid pore infi ll are estimated from a generalization of Brown-Korringa Equation. Effective elastic properties of bulk rock frame fi lled with a fl uid are obtained from Gassmann equations. Results show that increasing the TOC volumes generally reduces both P-wave and S-wave velocities, acoustic impedance, and density. On the contrary, the vp/vs ratio increased as the impact of immature organic matter which will be more affecting shale rigidity than its compressibility.
