Abstract

The Increased industrial subsector in Indonesia each year have some negative impact on health in Indonesia. Exhaust emissions of industrial activities is one of the sources of air pollution that occurs continuously. Exhaust gas quality monitoring needs to be done regularly to control the level of air pollution as required under KepMenLH 13/1995. During the determination of the opacity of the black smoke chimney industry performed manually using Ringlemann. Results opasitasbergantung on the observer on the ground so that the level of accuracy obtained is still less opacity akurat. Paper is about the development of imaging technology for monitoring parameters of black smoke in the exhaust stack opacity industri.Metode measurement used in this monitoring is a method Ringlemann. Segmentation algorithm used in this research is using thresholding. The result of the automatic segmentation using thresholding sample data has a high degree of accuracy, but still dependent on weather conditions. If you do smoke segmentation when the sky is clear, the level of accuracy of the segmentation is very high, but it is different when overcast or cloudy weather conditions. Results from this study is the obtainment function to be able to determine the level of black smoke opacity parameter. Searches made through a logarithmic function. Determination of the proper function is determined by looking at the highest value of Rą¬¶. Different sky conditions lead to different functions, so the algorithm functions to determine the parameters of black smoke opacity made in some circumstances under the conditions of the sky.

Abstract

Distribution of medical facilities in Indonesia is uneven, so residents in remote islands have difficulties to reach it. We need to build health boat, a floating facility that provide standard services like in the hospital, especially in Derawan and Tarakan Islands in East Kalimantan. This Health boat has a homebase in Balikpapan. Therefore, the condition of the sea between Balikpapan, Derawan, and Tarakan need to be reviewed. One method to determine the condition of the sea is analysis of meteorological and oceanographic, which enable us to get the maximum wave height estimation. Long tern wave forecast can be obtained by using statistical methods of measurement to provide data of high wave in 1, 10, 25, 50 and 100 years.

Abstract

Global warming is caused by various factors, one of them is the emission of CO2. Time series data of CO2 emission will be analyzed using moving average and exponential smoothing to forecast the CO2 emission of the period ahead. Both models provide estimates of forecasting based on the average value of the previous data and can be used for forecasting time series data containing trend component. The best models are selected based on the smallest error value based on the criteria of MAPE, MSD, and MAD

Abstract

Degradable Organic Carbon (DOC) is the important element in forming CH4 in a pile of garbage in the landfill. The calculation of the potential of methane (CH4) in the landfill become the basis for control and management of GHG sourced from landfill. Estimated value of the content of DOC used calculating the weight of municipal solid waste that goes into landfill every day, counting the value of the fraction of the composition and content of dry matter of municipal solid waste by 11 components of garbage (food, paper / cardboard, gardens and parks, nappies, wood, textiles, rubber / leather, plastic, glass, metal and sampahlain etc.), to further multiplied by the fraction of a default value content of DOC in each component of trash and garbage in total. The calculations show that the total weight of waste that goes to landfill every day at 14594.05 kg / day with the largest waste composition in the form of junk food at 49.54%, followed by plastic waste (13.76%) and the smallest is junk metal composition by 1.18%. As for the fraction of the dry matter of the highest value was found in the garbage rubber / leather by 95.31%, followed by wood waste amounted to 78.61% and the smallest value was found in the garbage nappies by 17.43% and 21.23% of food waste. Based on calculations using the value of the total garbage in, the fraction of the composition and the fraction of dry material content and the fraction of DOC.

Abstract

Polypropylene with added Microfibrill Cellulosa as additive materials and filler has been investigated. Polypropylene and sorghum fibre has different interface properties, as the result that the compatibility between both are not good. Therefore, modification process for sorghum fibre is needed, the modification process for sorghum surface are alkalinization and bleaching treatment. Alkalinization process is doing with soaking the sorghum fibre in NaOH solution 2% during 2 hours. Bleaching Process used buffer and NaClO2 during 4 hours. Then, polypropylene and microfibrill cellulose mixed with hot melt mixing method. Characterization for this research is how effect from cellulose in sorghum on crystallization of PP. From DSC analysis showed PP with added microfibrill cellulose 1%wt can increase crystallization temperatures up to 126,510C and crstallization time until 8,26 minutes. And the crystallization process may be accelerated 10 seconds.
