The residential sector is the biggest electric energy user in Indonesia. In this sector, there is a potential electricity saving of up to 30%. This savings can be obtained by implementing energy conservation. Energy use intensity (EUI) is a measure in assessing the efficiency of a building. From the EUI value can then be determined the efficiency criteria of a residential building, is it very efficient, efficient, moderately efficient or wasteful. An energy audit application was developed to facilitate in assessing the efficiency of a residential building in consuming electricity. The efficiency assessment in the model building shows that there is a significant electricity saving after the conservation efforts conducted, even though the model building is included efficient in the use of electrical energy.

The quality component measurement of horticultural products becomes more important to achieve better quality products also to obtain uniform product. Recently, measurement by non-destructive methods turns out to be more needed, because consumers become more selective and demand producers to develop a quick, effective and accurate quality assessment system. Near Infrared Spectroscopy (NIRS) can measure plant contents quickly, relatively economical in a bigger scale, and importantly non-destructive. The measurement of quality components of green bitter gourd, such as firmness, water content, total soluble solid, and color, are important but have not been widely conducted. This research was conducted from June to August 2013 at Post Harvest Laboratory, Faculty of Agriculture, Padjadjaran University, Sumedang, Indonesia with PLS regression modeling method. The results show R-value and standard error of 0.91 and 0.47 for water content, 0.93 and 1.03 for firmness, and 0.95 and 0.49 for a* value of fruit color.

Coal is a hydrocarbon fuel consisting of a mixture of substances containing carbon, hydrogen, oxygen, and containing less sulfur and nitrogen. Utilization of coal as fuel, especially in large scale causes methane gas emissions that can increase the impact of global warming, causing a decrease in environmental quality. Methane gas emissions in coal combustion are influenced by coal proximate and ultimate analysis. Proximate analysis includes moisture content, volatile matter, and fixed carbon, while ultimate analysis is carbon, hydrogen and oxygen. This study aims to determine the analysis of the effect of proximate, ultimate, and caloric value of methane emissions in coal combustion. This research is experimental, using quantitative method with descriptive and associative approach. The effect of proximate analysis, the lower the calorific value, the higher content moisture, the time and duration of coal combustion will be longer. Coal 5674 cal / gr, burning time 65 minutes, combustion length 39 minutes, moisture content 14.85%, coal 5747 cal / gr, burning time 60 minutes, duration of burning 31 minutes, moisture content 14.71%, coal 5617 cal / gr, burning time 49 minutes, combustion length 28 minutes, moisture content 12.17%, while coal 6992 cal / gr combustion time 38 minutes, combustion time only 4 minutes, and mosisture content 3.53%. Volatile matter in coal will affect the incubation period, the higher the volatile matter of the incubation period the faster. Coal 5617 cal / g incubation period 21 minutes, volatile matter 39.20%, coal 5674 cal / gr incubation period 26 minutes, volatile matter 38.39%, coal 5747 cal / gr, incubation period 29 minutes, volatile matter 39,30 %. For coal 6992 cal / gr incubation period 34 minutes, volatile matter 18.13%. The effect of ultimate analysis, the higher the carbon content, the higher the fixed carbon content, and the lower the hydrogen, the higher the calorific value of the coal and the less methane gas emissions. While the higher the oxygen content, the more burned the coal will be, the faster the incubation time and the longer burning time, so that the emissions of methane gas out into the atmosphere will be more and more.

Roads was built on swamp areas should be consider the condition of the base soil, since the characteristics of the soil in swamp areas have always inundated and have a low soil carrying capacity (Subagyo, 2006). One of effort that could be done to improve the existing soil condition was used fly ash as a material for soil stabilization (Indera et al, 2016; Mina et al, 2016). This study was conducted to analyze the enhancement of CBR value on various soil types in swamp area by the addition of fly ash. Testing on the values of index properties, compaction, and CBR values was done in laboratory base on ASTM and AASHTO standars. The test results show that the type of soil at the location of the sampling is silty or clay gravel and sand, clay soil, and silty soil. The reduction of optimum water content after the addition of fly ash is the highest decrease of 20.92%. While the highest increase of dry content weight after the addition of fly ash was 0.904 gr / cm3. An enhancement in the value of CBR by the addition of 20% fly ash in the study area, however the increase magnitude depends on the existing soil types, ie 7.99% in the silty or clay gravel and sand, 6 - 8% in the clay soil and 0,22 - 5% on silty soil. This indicates that the addition of fly ash was the optimum used on the type of clay soil.
