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

Research already did by resistivity method (custody species) schlumberger configuration that aim to know of rocks bottom surface structure in alteration zone are district of Gunung Kidul D.I Yogyakarta. Measurement points this research was measured as many as nine sounding points with each disquisition long were 75 m, 100 m and 120 m. the result of interpretation showed that of rocks bottom surface structure in alteration zone area were closed mantle (soil) with resistivity value 9,57 Ωm 14 Ωm on depth (0 – 0,75) m, , clay stone (6,86 – 42,1) Ωm in depth (0 - 9,22) m, sand stone (0,966 – 3,44) Ωm in depth (2,79 – 21,7) m, larva (841 – 1703) Ωm in depth (9,48 - ∞) m. Lava that had alteration was marked by resistivity value which small relative compared with lava which still fresh, this is due to lava which has alteration in area this suspected contain mineral metal so that reisitivity value smaller. lava which had alteration was there in point 1,4 dan 5 with resistivity value 40.5 Ωm – 95.2 Ωm in depth 0 m -∞. While at point 2, 3, 4, 6, 7, 8, 9 there type some structure is: closed mantle (soil), clay stone, sandstone and lava.

Abstract

This study aims to detemine the effect of thickness on the absorption coefficient of acoustic boards from corn waste and coconut fiber with polyester resin adhesive. The procedure used is used in the research carried out by making acoustic boards with two types of samples, which are fine chopped materials and materials that have been roughly cut with a thickness of 0.7 cm, 1.0 cm and 1.5 cm and measure the coefficient absorption of the thickness of the acoustic material board. The frequency value used is 200 Hz, 250 Hz, 500Hz, 1000 Hz, 2000 Hz and also 4000 Hz. Based on the results of research conducted, it is found that the absorption coefficient value of straight-line coefficient, where the thicker a material, the smaller the coefficient of absorption. Sound absorption coefficient is good, namely at all thicknesses with a frequency of 200 Hz, 250 Hz and 500 Hz both from fine counts and rough counts. This shows that acoustic boards made of corn husk and coconut fiber can be used as sound absorbers because they have been included in the requirements of the ISO 11654 standard.

Abstract

This research was conducted at the hospital. Level II Pelamonia Makassar South Sulawesi. Formulation of research problems, namely (1) determine the ratio between the pressure fluid infusion and blood pressure for patients with discharge or severe nutrition in children, adults and the elderly, and (2) determine the flow rate of fluid infusion for patients experiencing discharge or severe nutrition in children children, adults and elderly. In this study the parameters under study is a comparison of blood pressure measured by a sphygmomanometer with intravenous fluid pressure in pediatric patients, the mature and elderly, as well as the flow rate of fluid infusion for pediatric patients, adults and the elderly who experience severe fluid and nutrients. Comparison of the patient's blood pressure and infusion pressure and flow rate of intravenous fluids known through calculation of several variables that have been measured and calculated. The results showed that (1) measured blood pressure values corresponding with the calculated pressure fluid infusion in pediatric patients, adults and the elderly based on the events of osmosis and (2) the flow rate of intravenous fluids to children gained an average of 6.669×10-9 m3/s (on the calculation of Q = A.v) or an average of 5.558×10-9 m3/s (on the calculation Q = V/t), while adults and the elderly gained an average of 2.001×10-8 m3/s (calculation result Q=Av) or 1,667×10-8 m3/s (on the calculation Q=V/t). This means that the flow rate of fluid infusion for pediatric patients less than the infusion flow rates for adults and the elderly.

Abstract

This research aimed to identify the location of accumulation and distribution direction of the spread of leachate at landfills Tamangapa around Makassar Multichannel Resistivity meter resistivity measurements using the form of the voltage injected into the subsurface through a predetermined trajectory as much as six trajectory. The method used is Geolistrik resistivity method with Wenner-Schlumberger configuration. Data processing is done by using RES2DINV to generate a 2D cross-section of data below the surface, and use Voxler 3 to determine distribution direction and location of the accumulation of leachate seepage of leachate . Based on the location of the results obtained by the accumulation of leachate generated from landfill waste decomposition Tamangapa Makassar interpreted to be at a depth of 2.50-18.52 m with apparent resistivity values from 0.0090-5.00 Ωm at coordinates 5017'727''LS and 119049'084''BT elevation 16-20 m above sea level. While the distribution of leachate seepage direction around Tamangapa Makassar interpretation in sector 1 seepage eastward direction which is at coordinates 5017'594''LS and 119049'202''BT with a depth of 2.50-12.80 m. In the second sector is interpreted towards see page of leachate to the west which is at coordinates 5017'727''LS and 119049'084''BT with a depth of 2.50-31.87 m.
