Abstract

Research aims: This research aims to evaluate the development of performance indicators using the performance blueprint analysis tools and know what factors are instrumental in the development of performance indicators for public organizations in Indonesia using Institutional Isomorphism point of view.Design/Methodology/Approach: The study comprised qualitative research undertaken at one public organization, the Indonesian Financial Transaction Reports and Analysis Center (PPATK) in Jakarta.Research findings: This study revealed that the PPATK business process was still not optimally aligned with the performance blueprint analysis tools. This study also uncovered eleven factors that play a role in the development of performance indicators: mindset, business process, comfort zone, technical competence, regulation, activity plan, process, drafting, management commitments, monitoring and evaluation, reward and punishment, and performance data management.Theoretical contribution/Originality: This study contributes to knowledge of the institutional isomorphism’s influence, primarily normative isomorphism at a public organization. Also, this research is the first research to use the performance blueprint more thoroughly, with six types of analysis.Practitioner/Policy implication: This study has implications for ministries/institutions and regulatory agencies to implement the performance blueprint in the development process of performance indicators.Research limitation/Implication: The limitations of this study are that the results of the performance blueprint analysis tools did not yet have the criteria as the basis for assessment of findings, and this research only employed a qualitative method; therefore, the resultant conclusions are still minimum.

Abstract

An airlift pump can be used to move from one location to another. The pump lifts liquid or solid particles from air bubbles through a vertical pipe. In this experiment, the airlift pump system was modified using a microbubble generator installed on the injector to produce air bubbles. Two injectors were installed with a swirl model. This study aims to visualise the flow pattern that forms in a vertical pipe when air bubbles lift water toward the endpoint. The flow pattern was observed by varying airspeed and water column h in the vertical pipe. The method in this study was carried out using a two-phase flow (air-water). An acrylic pipe with an inner diameter of 50 mm and a height of 327 cm was used in this study. The immersion ratios were set to 0.44, 0.50, 0.56, 0.62, and 0.68. Air was injected into the system through a compressor injector, and air release was controlled by an airflow meter. m ³/h, 1.5 m ³/h, 2 m ³/hour, 2.5 m ³/h, and 3 m ³/h. The flow pattern in the thriller pipe is captured using a video camera. The research results show that bubble, slug, churn, and annular flow patterns are formed owing to variations in the airflow injected into the system. The slug flow changed to an annular flow as the slug flow speed increased. The slug and churn flows lifted the water, and the annular flow reversed the buoyancy force of the slug and churn flows. This study concludes that the ratio of the water column height in the vertical pipe affects the driving force for lifting water to the separator. The greater the immersion ratio, the better is the pump performance. In addition, the influence of the injected airflow forms a flow pattern that can move water from the bottom to a certain height.
