Abstract

This research to discuss the Government's strategy to increase public acceptance toward nuclear power development plan. The purpose of this research is to obtain recommendation for government’s strategy. It is design as descriptive qualitative one with design research. The results showed there are two strategies, namely; strategies of socialization through counseling and through online media. Based on the research, it is recommended that the government should establish a Coordination Board which is under the command of (under command) specifically in the case of nuclear power plants in Jepara.Keywords: Nuclear Power Plant; Community acceptance; The government's strategy.

Abstract

Women are becoming more active in the defense industry. Since the morphology of the female body differs from that of the male during military activities, it is required to modify personal protection equipment to accommodate the female body shape. According to a literature review, a survey of a sample of female soldiers from different nations revealed that they felt the impacts of breast soreness when running, as well as a sense of "distorted breasts" and breathing difficulties. The woman's petite frame and the bulky, hefty bulletproof jacket both draw criticism for their respective dimensions. Using 3D design technology, a female mannequin with a 95B breast size was scanned in order to create a bullet-proof vest that is tailored to the contour of a woman's body. Changes in the breast's contour, which affect changes in the surface point parameters, result in adaptive breasts. Utilizing a combination of carbon fiber and 16 percent HGM epoxy, bullet-proof vests can be modified to provide lightweight dimensions and have the benefit of good ballistic resistance. This results in a material that is 20 mm for thick, 1,348 kg in weight, and capable of absorbing 348.27 Joules of energy from bullets. The results of this research are not optimal, so developments are needed in further research.

Abstract

The performance of the Electronic Engine Control (EEC) system is essential for ensuring safe aircraft operation following engine maintenance. This study evaluates the EEC performance of a CFM56-7B turbofan engine during an on-aircraft Engine Ground Run-Up (EGR) test conducted after engine replacement on a Boeing 737-800 Next Generation aircraft. The test was performed under controlled ground conditions in accordance with the Aircraft Maintenance Manual, and key EEC-controlled parameters—including fan speed (N1), compressor speed (N2), exhaust gas temperature (EGT), fuel flow, lubrication parameters, and engine vibration—were recorded using the aircraft’s built-in sensor system. The results indicate that all monitored parameters remained within manufacturer-specified acceptance limits during engine start, idle, Maximum Power Assurance, and static take-off power conditions, demonstrating stable EEC regulation under both transient and steady-state operation. Fuel consumption during the EGR procedure was consistent with the applied power settings, reflecting appropriate fuel scheduling. Comparison with representative test-cell–based studies show similar performance trends, with expected differences in thermal behavior attributable to on-wing installation effects during ground operation. Overall, the findings confirm that on-aircraft EGR testing provides an effective and operationally representative approach for post-maintenance validation of EEC performance, bridging the gap between test-cell evaluations and actual aircraft operation.
