THE ROLE OF LOCAL WISDOM AS PART OF CORRUPTION ERADICATION STRATEGY
Authors: SETIADARMA LIM KURNIAWAN 
Published: February 2018

ABSTRACT Corruption has been a pervasive problem plaguing our country for a long time. On the other hand, raising community awareness and enhancing public participation have been acknowledged as part of the corruption prevention and eradication strategy in Indonesia for many years, especially since the enactment of 1999 Corruption Law. Nonetheless, public participation in the country seems to keep decreasing throughout the years, leaving corruption alone eroding every sector of society. For this reason, it is important to realize that the success level of public participation is highly related to the existing beliefs and values of people that are expected to be participating – the local wisdom. The purpose of this paper is to evaluate the effectiveness of public participation in eradication of corruption, assess whether the local wisdom has been supporting the corruption eradication/prevention strategy, and finally conclude with a proposition to maximize the role of local wisdom in combatting corruption in Indonesia. To achieve that goal, delving into applicable laws, general principles of law, journals and books, cases and reports, as well as various surveys becomes very important to increase the knowledge and objectivity in thinking and analyzing. Two surveys were also conducted to Indonesian citizens with 328 respondents and 495 respondents, in order to see the real cultures and beliefs that are currently developing in Indonesian society. This research paper will reveal the current Indonesian local wisdom on the ground and its connection to the large strategy of corruption eradication at national level.

With the continuously increased speed of the high-speed train, the lateral aerodynamic performance of high-speed trains has attracted more and more attention. Under strong crosswinds, the aerodynamic performance of trains deteriorate and air drag, lift and lateral forces borne by trains quickly increase, which has an impact on the lateral stability of trains and even leads to train derailment. This paper adopted computational fluid dynamics theory to establish an aerodynamic model for a high-speed train, computed aerodynamic forces and moments acting on the high-speed train and obtained the unsteady flow field of the high-speed train. In the meanwhile, this paper combined with multi-body system dynamics theory to establish a system dynamics model for the train and analyzed the safe aerodynamic performance of the high-speed train under cross winds. Computational results showed: Under cross winds, the aerodynamic performance of the high-speed train had a random fluctuation. When wind direction angle was 90°, aerodynamic forces (drag, lift and lateral forces) and moments (overturning moment, shaking moment and nodding moment) borne by the high-speed train were the largest; train speed was a main factor affecting the size of positive pressures of train and cross wind velocity had no obvious impacts on the positive and negative pressures of train body; the aerodynamic forces and moments of the high-speed train had a random fluctuation within a certain range with time; the frequency for the peak value of power spectral density of lateral forces of head train was within 25 Hz and the peak value of power spectral density was the largest when the main frequency was 1.6 Hz; the frequency for the peak value of power spectral density of overturning moment of head train was within 20 Hz and main frequency was 0.57 Hz. When the cross wind speed was 15 m/s, all safety indexes of the high-speed train running at the speed of 250 km/h were within the range of limited values and satisfied design requirements. Aerodynamic performance of the high-speed train with the suction chamber under the cross wind was computed and compared with original results. Aerodynamic force and force moments of the high-speed train under cross wind will be reduced obviously and running safety of the high-speed train can be improved through application of the suction chamber.
Creation of innovative earthquake resistant steel buildings by dividing the structure into inner and outer parts having interaction by hysteretic dampers

Published: February 2018

In conventional seismic design codes of building structures severe structural damage due to large earthquakes is accepted, provided that the structure does not collapse, and life safety of the residents is guaranteed. The extent of this allowed damage can be so high that after earthquake, demolition and reconstruction of the building becomes inevitable, particularly in near-fault areas. The idea followed in this study is to relocate the damage to some predetermined fuse elements, other than the main structural members, so that the building could be quickly and easily repaired, even after major earthquakes. For this purpose, dividing the building’s structure into two inner and outer parts with different dynamic characteristics, and creating dynamic interaction between them by using yielding plate or hysteretic dampers was investigated. At first, a 5-storey building model was developed and divided into two interactive parts using hysteretic dampers at roof level, and it was tried, by developing a code in MATLAB environment for solving the nonlinear equations of motion, to find the optimal values of the initial stiffness and the yielding strength of dampers, assuming their behavior to be elastic-perfectly plastic. The results of nonlinear time history analyses (NLTHA), by using a set of selected earthquakes accelerograms, showed that by using appropriate initial stiffness and yield strength, the inert-story drifts of both inner and outer structures can be significantly reduced. Then, 5-, 8- and 11-story steel braced buildings were designed by ETABS, and were divided into inner and outer substructures, and then were modeled in PERFORM-3D software using hysteretic dampers with optimal stiffness and strength, obtained from the MATLAB program, and the seismic responses were compared. Final results of the NLTHA show that the inter-story drift values of outer and inner substructures decreases in average by 20 % and 65 %, respectively, comparing to the original structure. This drift reduction leads to decrease of the damage indices of outer and inner substructures by almost 20 % and 80 %, respectively, comparing to the original structure, making it possible in most cases to have an easily repairable structure.

Authors: Yin Hong 
Published: February 2018

ABSTRACT: In May 2015, Alexandria Renew Enterprises (AlexRenew), a 204,412 m3/d advanced resource recovery facility, started up a centrate pretreatment (CPT) system. This system utilizes the sidestream deammonification process (DEMON®) to remove nitrogen in the centrate produced from dewatering anaerobically‐digested sludge. During the startup period, the ammonia and total nitrogen removal rates averaged 89 percent and 78 percent, respectively. The CPT system startup encountered a number of operational issues including centrate quality, nitrite control, excess polymer and micronutrient deficiency etc. These challenges were identified and addressed primarily through operational and process control measures. The CPT process reached 100% plant centrate production (0.5 kg N/m3/d) after 18 months of startup period. This paper summarized major challenges during the startup phase of the CPT system from an operational standpoint, documented our approaches and learnings to tackle each problem and shed some light on future improvement.
