Abstract

As a developing country that still has to develop in all fields and to maintain its economic development, the Indonesian government requires significant funds for development. To fulfill the lack of funds obtained from the tax, the Indonesian government sells bonds. Indonesia's 10-year government bonds are known as Surat Utang Negara (or abbreviated as SUN). This study aims to confirm whether the inflation rate, exchange rate, political stability, and corruption control affect the yield of SUN. The research uses descriptive methods and explanatory studies with secondary data based on systematic sampling of periods chosen from January 2013 to December 2019. Multivariate regression equation models were used with a significance level of 5% for the t-test. The conclusions are: partially and simultaneously inflation rate, exchange rate, control corruption, and political stability have a significant effect on the Indonesian Government Bond. This research found that deteriorating political stability and control corruption would cause government bond yields to increase

Abstract

Research and aerodynamic testing of BLP-500 and BLP-25 have been conducted in both subsonic and supersonic wind tunnel. Aerodynamic characteristics such as Cl, Cd, and Cm for these types of bomb we obtained. By knowing the aerodynamic characteristics, the stability and trajectory of the bomb can be determined. Both analytical calculation and real tests in the wind tunnel were performed and compared. The results showed that for its static stability, the location of the centre of gravity of BLP-500 and BLP-25 to be less than 115.1 cm and 31.9 cm respectively.

Abstract

Static pressure stream analysis has been done on the surface of pitot static for LAPAN transonic wind tunnel by means of numeric and analytic methods. Static pressure hole is placed at 25 cm behind static pitot leading edge. Numerical analysis result demonstrates that shock wave begins to rise under free stream with velocity of 0.9 march. Shock wave occurs in an area around static pitot leading edge so the stream velocity around static pressure hole almost equal with free stream velocity. There is shock wave that cause decreasing of stream total pressure. By known the total pressure and streamn velocity around static pressure hole then static pressure can be calculated. Mach number in the test section can be known from pressure ratio. Keywords: Static pitot, Shock wave, Static pressure, Transonic.
