Universitas Brawijaya added two new professors from two different faculties. These two professors are Prof. Drs. Nurkholis, M.Bus., (Acc), Ak., Ph.D from the Faculty of Economics and Business and Prof. Dr. Ir. Bambang Susilo, M.Sc. from the Faculty of Agricultural Technology.
Prof. Drs. Nurkholis, M. Bus. (Acc.), Ak., Ph.D. : Integrated Public Accountability Model: Efforts to Optimize Public Sector Accountability in a Complex Environment
The management of public organizations faces challenges amid conditions of turbulence, emergencies and uncertainties. Unfortunately, the existing public accountability models have not been able to accommodate the need for a more comprehensive implementation of public accountability.
To accommodate accountability, Nurkholis offers an integrated model that seeks to optimize public sector accountability in a complex environment. This model has the advantage by reminding the needs of all affected stakeholders and being able to support the achievement of public organization goals in realizing well-organized organizational management based on applicable law (Eunomia).
He believes that achieving optimal public accountability requires support from related factors. Thus, the integration of various aspects, both technical and non-technical, is a necessity. “Based on this understanding, the public accountability model must also have an integrality character, with four pillars, namely spirituality, institutional capacity, social response accounting, robust governance and locality or customary law,” he explained.
“The integrated public accountability model that I have developed has attempted to accommodate important aspects that can ensure optimal achievement of the implementation of public accountability itself,” he explained.
Public organizations, he explained, must realize that the latest environmental complexities have multidimensional effects, so that identification of parties receiving performance information really needs to be done holistically.
Prof. Drs. Nurkholis, M. Bus. (Acc.), Ak., Ph.D. is the 23rd active professor in the Faculty of Economics and Business. The man who once served as Dean at the Faculty of Economics and Business is a professor in the field of public sector accounting, who is now the Director of Non-Academic Enterprises, Universitas Brawijaya.
Prof. Dr. Ir. Bambang Susilo, M.Sc.Agr : Ultrasonic Technology for Processing Plant Oil into Biodiesel
Biodiesel is a very prospective diesel fuel substitute for development, because the wealth of biological resources in Indonesia is very diverse. Biodiesel is produced by utilizing plants such as nyamplung, sea pandan seeds, palm oil, and cotton randu seeds.
Biodiesel production generally uses heat energy input to increase the temperature so that the reactants reach the activation energy. This process uses a mechanical stirrer for mixing raw materials, with technological developments that are still difficult to apply on an industrial scale.
“We are developing the application of ultrasonic technology to improve the biodiesel process. This technology uses a frequency above the frequency that is perceived by the human sense of hearing, “he explained.
This technology allows it to be developed on an industrial scale, used for the extraction of biological oils as raw material for biodiesel and also for the extraction of other biological compounds. The weakness of ultrasonic technology for biodiesel production is that it still predominantly uses batch systems and inorganic catalysts. In the future, it is necessary to develop a continuous process system that is technically feasible, economically viable, environmentally friendly using renewable catalysts made from biological materials and its application in industry
The use of ultrasonic exposure accelerates the trans-esterification process time by up to 30 times faster than the use of a mechanical stirrer. The relatively short time to reach this maximum curve allows the trans-esterification machine with ultrasonic waves to be designed with a continuous system because the quiet time required in the reactor is relatively short.
The use of ultrasonics in the trans-esterification reaction is able to convert plant oil into biodiesel up to 100% with a much shorter processing time compared to a mechanical stirrer. This is due to cavitation, acoustic flow and hot spots in the reactants.
“The development of bioenergy, especially biodiesel, is expected to integrate processes from upstream to downstream, and can be prioritized for rural industrial development because many sources of raw materials are available in the village”, he explained.
The man who once served as Vice Rector for Innovation is a professor in the field of Agricultural Product Processing Engineering. Prof. Dr. Ir. Bambang Susilo, M.Sc. Agr is the 13th professor in the Faculty of Agricultural Technology, and the 176th active professor in and the 325th professor produced by Universitas Brawijaya. (VQ/ UB PR/ Trans.Iir)
