Abstract

The research was conducted by taking a sample of 25 pieces of cell phone. Mobile radiation intensity measured electromagnetic waves are receiving phone calls. Measurements were made by placing two headphone in a different room with a range of ± 20 meters. Tool used to measure the intensity of radiation of electromagnetic waves emitted by mobile phone radiation is a measure C32-QX5. Values were collected before phone calls and performed on two conditions after receiving the phone call is a normal condition and the condition of the loudspeaker. The purpose of this study was to determine the intensity of the electromagnetic radiation emitted by mobile phones with different brands and types and determine their effects on health.Results showed that all cell phones that have measured the intensity of the radiation was still safe to use because it has an average radiation intensity 6 mW/cm2, which limits the intensity of radiation that can be tolerated by the body is equal to 10 mW/cm2. The use of mobile phones continuously for one hour a day in the ten-year timeframe, estimated the value of the intensity of radiation received by the body tissue will exceed safe limits.Key words: Intensity Radiation, Measures Radiation, Mobile phone and Health Risk

Abstract

Energy is one of the most hot issue today.  Energy consumption has increasing every year around the world but the sources  not increasing significanly.  Most of the energy source come from coal and oil with decrease every year. However oil and charcoal tends to be distinctive near future since it not renewable. Besides, it is polluting, environmentally harmful and rather expensive. As consequence  it is important to explore another renewable energy resources. One good example is solar energy, with using sel phovoltaics technology. Photovoltaics technology have been presented with higher efficiency and low cost in production such as perovskite solar cell.

Abstract

This research aims to find out the  quality of the water as it had been filtered from the single of active carbon, silica sand and gravel as the media filter. And also to know the quality of the water as it had been filtered from the combination of active carbon, silica sand and gravel as the media filter. The quality of the water filtered was measured by both physic and chemistry parameters, either parameters were measured and observed directly at the Modern Physic Laboratory of Science and Technology Faculty and at the Physic Chemistry Laboratory of  Science and Technology Faculty. The quality of the water which had been filtered by the aforementioned filter materials then met the requirement as pure water based on the water authentic quality standard (South Sulawesi Governor Rule Number 69, 2010), the water then can be used for the daily household necessity such as bathing, watering plant, laundry, and so forth.

Abstract

Fresh and clean water is portable increasingly rare inurban areas.The rivers become the source was contaminated waste of all kinds, ranging from the elimination of organic waste, household hazardous waste to the industry. By adopting this approach the research system of water treatment with domestic sewagerecharge wells.This research was conducted in Garaganti Samata Gowa. This research is set in wells model (two wells model), firsly with tree wells and the secondly in single well which each well containing filtration materials. The results show that significant water output  are colorless, harmless and wasteless both in tree wells by partition and single well Infiltration wellshave two models. This indicated that the wells working good as like as expected. To show the quality and classify of the water output, samples are send to laboratory of Badan Lingkungan Hidup Daerah (BLHD) Province South Sulawesi, with descriptive method presented in tabular form. Result of from BLHD are compared with standart shows that the water output is clean (Peraturan Gubernur No. 69 Tahun 2010 about water quality standard limits an criteria for environmental life damaged), classified in Class III (Peraturan Pemerintah No. 20 Tahun 2010 about water quality and water allocation) and Peraturan Pemerintah No. 82 tahun 2001 about water quality criteria based on class
