This paper discusses the results of two years continuous operation of automatic self-cleaning air filtration systems designed to provide gas turbine protection in a desert environment subject to high ambient concentrations of sand, dust and salt. The condition of the gas turbines and associated pulse-jet air filtration systems, after two years continuous operation, are described. Filter operating costs are also analyzed.

The production of rubber modified thermoplastics can exceed rates of 30,000 pounds per hour. If a production plant needs to equilibrate or has an upset, that means operating costs and lost revenue. Results of transmission electron microscopy (TEM) can be used for process adjustments to minimize product loss. Conventional TEM, however, is not a rapid turnaround technique. The TEM process was examined, and it was determined that 50% of the time it took to complete a polymer sample was related to film processing, even when using automated equipment. By replacing the conventional film portion of the process with a commercially available system to digitally acquire the TEM image, a production plant can have the same TEM image in the control room within 1.5 hours of sampling.A Hitachi H-600 TEM Operated at 100 kV with a tungsten filament was retrofitted with a SEMICAPS™ image collection and processing workstation and a KODAK MEGAPLUS™ charged coupled device (CCD) camera (Fig. 1). Media Cybernetics Image-Pro Plus software was included, and connections to a Phaser II SDX printer and the network were made. Network printers and other PC and Mac software (e.g. NIH Image) were available. By using digital acquisition and processing, the time it takes to produce a hard copy of a digital image is greatly reduced compared to the time it takes to process film.

Investigation in various regions in Indonesia found indications of the alleged fraud that result from unccountable use and management of BOS funds. Among the findings, including payments that do not fit the technical guidelines, no accountability report, and the use of funds with unaccountable receipt. In the Regulation of the Minister of Education and Culture of the Republic of No. 161/2014, stated that: BOS is a government program that is basically forfunding the nonpersonnel operating costs of the primary education as the implementer of compulsory education program. The purpose of this study were (1) to analyze the accounting cycle and financial accountability for the use of BOS funds in the 2015, (2) to analyze the compliance of the accounting cycle and financial accountability of the BOS funds, (3) to analyze the transparency and accountability of BOS fund’s reports. The observed elementary school is SDIT X in Depok, West Java. Result shows that they do not fully compliance to the appropriate regulatory technical guidelines. On the other hand, the transparency and accountability issues show that: (1) BOS Management Team, Teachers Council and School’s Committee’s involvement in the BOS fund management, and (2) evaluation and comparison of the final report of prior periods, so that transparency and accountability of the use and management of BOS funds can be improved.

In the animal feed industry, steam is used in pellet making machines. In this process, steam from the boiler is distributed to the pellet mill through the pipe. The purpose of this study is to observe the waste of electricity costs of operating a boiler by calculating heat loss in a distribution pipe. The method of assessing heat loss is done by calculating losses caused by heat loss in the boiler distribution. Then make a calculation application model based on the data obtained. From the data analyzed, the amount of heat lost in the non-insulating distribution pipe is 0.766 kJ/s with a loss of Rp 5.628,600 operating costs per month compared to heat loss in an isolated pipe condition of 0.047 kJ/s with losses which cost slightly more than Rp 368 190 / month. This heat loss calculation process is made on an android application by entering the calculation formula on the program and the data that has been obtained.
