APIP dalam Pelaksanaan Maturitas SPIP Government Internal Supervisory Apparatus in Implementing the Maturity of the Government Internal Control System

One of the problems that still occur in Indonesia today is the weakness of the Government Internal Control System (SPIP). This is indicated by the many findings of BPK's examination of weaknesses in the government's internal control system. In this case, there is a role for government internal auditors that are highly expected to create an effective and sustainable control system. This study aims to determine the effect of the role of APIP in implementing the Maturity of the SPIP at the Inspectorate Kab. South Solok. This research is a quantitative. The population and sample in this research were all government internal supervisory apparatus at the Inspectorate Kab. South Solok. Data collection technique used is through a questionnaire. The analysis technique used in this research is descriptive statistical analysis. The instrument were tested using validity test, reliability test, and normality test. Data analysis technique used is multiple linear regression analysis. The results showed that the role of leadership, internal supervisors, consultants, and catalysts had a positive effect on the implementation of the maturity of SPIP. While the role of quality assurance has a negative effect on the implementation of the maturity of SPIP.

Lattice Boltzmann Study of Flow Fields Around Stationary and Oscillatory Cylindrical Objects in Various Arrangements

Computational fluid dynamics is a fascinating and complex subject due to rapid development of computer technology, high level programming languages and new developed numerical techniques for unlimited set of different engineering applications. The study of wake structure mechanism behind the cylindrical objects is important for practical applications in wind engineering, aerodynamics, and electronics cooling. The main objective of this study is to systematically investigate the stationary and oscillatory flow problems using the lattice Boltzmann method. The oscillating flow fields are common flow fields in many practical situations like ocean engineering, off-shore structures and similar type of bodies located in a wave environment. Oscillatory motions of small amplitude are very important in the analysis of immersed vibrating bodies. Such motions alter the aerodynamic forces and the pressure distributions as compared to those of rigid body.This may also result to the lock-in phenomenon, where the shedding frequency of fluid becomes equal to the oscillating frequency of the object. On the other hand the oscillatory motions of larger amplitude alter the far flow fields which can be affective due to the presence of other bodies in the flow field. Therefore detailed information regarding the variations of flow fields due to oscillatory motions is very important for designing structures. This study will focus on three main points: (a) Flow past stationary cylinder at various arrangements, (b) Drag reduction in terms of small control cylinders (c) Flow characteristics of oscillatory cylinder arranged in side-by-side or tandem. All these results, most of which have been obtained for the very first time, are of fundamental significance in engineering applications
