The main purpose of this study is to investigate the effect of using three types of coarse aggregates (gravel, basalt and dolomite) and three different percentages of water and cement on the properties of selfcompacting concrete. To this end, nine mixes containing different percentages of water and cement were designed. Three types of aggregates were used namely; gravel, basalt, and dolomite. The all fresh concrete mixes were prepared to achieve standard workability (slump flow). The compression, splitting tensile, and flexural strength tests were carried out on hardened self-compacting concretes after 28 days. In the nine mixes, three types of aggregates (gravel, basalt and dolomite), three cement content (350, 400, and 450 kg/m3), and three water cement ratio (0.46, 0.42, and 0.38) were used. Results showed that. Slump flow of dolomite selfcompacting concrete is greater than all concrete mixes with gravel and basalt. The density of self-compacting concrete basalt mix is greater than other concrete mixes with gravel and dolomite. The compressive, split tensile, and flexural strengths of self-compacting concrete dolomite mix is higher than all concrete mixes with gravel and basalt.

This paper compares amount of thermal energy lost through exhaust gases when an engine was operated on diesel and biodiesel. The study used a 4.7 hp (3.5 kW) single cylinder, four-stroke, multi-fuel engine which was operated on diesel and biodiesel fuels. Experiments were conducted for the two fuels at engine speeds of 1000, 1250 and 1500 rpm in accordance with the manufacturer’s recommendations. The engine was tested for torque loads of 6 to 22 Nm at intervals of 4 Nm for speeds and fuels studied. The instrumentation of the engine was mainly equipped with data acquisition system and software for analysis. Exhaust gas mass flow rate and temperature measurements were used to determine lost thermal energy. Lost heat energy depended on the temperature of the waste heat gases and mass flow rate of exhaust gas. The energy lost in exhaust gases increased substantially with increased exhaust gas temperature. The results showed that more energy was lost through exhaust when the engine used biodiesel as compared to when it was fueled on diesel. Maximum heat loss through exhaust was 18.7% of fuel energy when the engine used biodiesel at a speed of 1500 rpm and a torque load of 14 Nm.

Green Supply Chain Practices have been known to have an impact on Green Supply Chain Performance [6].This paper tests empirically through a pilot study of the Indian Automobile Manufacturing Sector, the contribution of the eleven variables constituting the construct Green Supply Chain Continuous Improvement in Green Supply Chain Performance measurement. Also the paper establishes the reliability of the questionnaire instrument developed previously for measuring the construct Green Supply Chain Continuous Improvement and also for measuring the eleven variables that constitute the construct Green Supply Chain Continuous Improvement. Further the paper establishes the correlation among these eleven variables. Finally this paper conducts Confirmatory Factor Analysis (CFA) to arrive at a single factor (linear combination of eleven variables constituting the construct Green Supply Chain Continuous Improvement) to aid in measuring the construct Green Supply Chain Continuous Improvement. Finally the paper establishes the order of contribution of the eleven variables constituting the construct Green Supply Chain Continuous Improvement.

Fuel gas is the main fuel used in PT PJB UP Muara Tawar combined cycle power plant. Reliability of combinend cycle power plant can be affected with fluctuative supply of fuel gas. Fuel gas supplied by PGN with pressure range 24-26 barG. Because of fluctuative pressure from supplier, pressure of gas must be adjusted by using Gas Receiving Station (GRS) system. There are HMI local panel in GRS as interface. HMI local panel consist of bypass system and fuel gas compressor system. Bypass system used to decrease gas pressure when gas pressure above the upper limit while compressor used to increase gas pressure when gas pressure under lower limit. GRS have an important role in operational Block 5 PT PJB UP Muara Tawar. In 9 December 2011-26 Januari 2015 period, Block 5 can not be operated because of mechanical seal failure in fuel gas compressor in GRS. Ordering new seal has take a long time. GRS can not be operated when compressor gas fail due to fluctuatif pressure of supplied gas. Moreover, GRS has far distance from main control room (MCR). It will be difficult to monitor GRS parameter from control room. By this problem, research and improvement in GRS should be done so that performance of GRS can be improved. Improvement in low limit fuel gas pressure was performed. By this changing, inlet pressure GT operation has wider range. In addition, making 1K changeover can increase GRS performance. The addition of overview, parameters, alarm indicators on Alspa HMI can improve the reliability of the operation of Gas Turbine because the operator can respond faster when there is a change of parameters in GRS.
燃气是PT PJB UP Muara Tawar联合循环电厂使用的主要燃料。燃气供应的波动会影响联合循环电厂的可靠性。燃气由PGN供应，压力范围24- 26barg。由于供气压力波动较大，必须通过燃气接收站系统对供气压力进行调节。GRS中有HMI本地面板作为接口。HMI局部控制板由旁通系统和燃气压缩机系统组成。旁路系统用于在气体压力超过上限时降低气体压力，压缩机用于在气体压力低于下限时增加气体压力。GRS在Muara Tawar Block 5 PT PJB UP运营中发挥了重要作用。2011年12月9日至2015年1月26日期间，由于GRS燃气压缩机机械密封失效，Block 5无法运行。订购新的封条花了很长时间。当供气压力波动导致压缩机气体失效时，GRS不能运行。此外，GRS与主控制室(MCR)的距离较远。从控制室对GRS参数进行监控是很困难的。针对这一问题，需要对GRS进行研究和改进，以提高GRS的性能。对低极限燃气压力进行了改进。通过这种改变，进气压力GT运行范围更广。此外，进行1K转换可以提高GRS性能。在Alspa HMI上增加概述、参数、报警指标，可以提高燃气轮机运行的可靠性，因为当GRS中参数发生变化时，操作员可以更快地响应。

In construction industries concerte are basic requirement to built any construction. Concrete is manmade material which is used all over the world. Curing is the most important factor of the concrete to perform planned functions throughout designed life of structure while immoderate curing time may intensify the construction cost of project and irrelevant delay of project, where there is deficiency of water and on downhill surfaces where curing with water is problematic and in cases where large areas like pavement have to be cured. As stated earlier about the conventional curing methods the use of membrane curing compounds is very important from the frame of reference that water resources are getting precious every day. The upgrading in the construction and chemical industries have lead the way for development of new curing techniques and construction chemicals such as Membrane curing compounds, Self curing agents, Water proofing compounds. In this paper we will compare results of different grade of concrete and curing compounds with various climatic changes.
