Universitas Brawijaya (UB) again confirmed two professors from the Faculty of Law and Faculty of Engineering, Sunday (20/8/2023).
Prof. Dr. Imam Kuswahyono, S.H., M.Hum was inaugurated as the 9th active Professor at the Faculty of Law (FH) and the 176th active Professor at Universitas Brawijaya and became the 330th Professor out of all Professors produced by Universitas Brawijaya.
Prof. Dr. Ir. Sudarminto Setyo Yuwono, M.App.Sc was inaugurated as the 10th active Professor at the Faculty of Agricultural Technology (FTP) and the 177th active Professor at Universitas Brawijaya and became the 331st Professor out of all professors produced by Universitas Brawijaya.
Prof. Dr. Eng. Denny Widhiyanuriyawan. S.T., M.T was inaugurated as the 19th active Professor at the Faculty of Engineering (FT) and the 178th active Professor at Universitas Brawijaya and became the 332nd Professor out of all the Professors produced by Universitas Brawijaya.
Meanwhile, Prof. Dr. Eng. Nurkholis Hamidi, S.T., M.Eng. as the 20th active professor at the Faculty of Engineering (FT) and the 179th active professor at Univeritas Brawijaya and the 333rd professor of all professors produced by Universitas Brawijaya.
Prof. Dr. Imam Kuswahyono
Prof. Imam was inaugurated as a professor of law who delivered a scientific oration entitled “Pancasila-Based Regulatory Model for Sustainable and Just Management of State Property”.
In his scientific oration, Prof. Imam explained that the “Pancasila-Based Regulatory Model”, namely the model of “the highest and best use state asset management based on Pancasila” as a new concept to fill the vacuum norm related to the management of state property, including the absence of a mechanism for managing and resolving disputes.
This model elaborates the legal politics of Pancasila into laws that regulate the management of state property with the principle of the best utilization orientated towards the welfare of the people.
Prof. Imam explained that in order to realize this goal, a State Asset Management Agency and an Agrarian Court must be formed as special courts. The weakness of this idea lies in the realization of the formation of regulations that require harmonization of related laws and regulations.
Prof. Dr. Ir. Sudarminto Setyo Yuwono, M.App., Sc
Prof. Sudarminto was inaugurated as a professor in the field of Food Processing Engineering who in his scientific oration explained the Process Variable Management Model (Mpv-Pro) as an Effort to Increase Yields in the Tofu Industry.
In his presentation, Darminto highlighted the problem of increasing the price of soybeans as a raw material for tofu production. The tofu industry is required to be able to carry out an efficient production process but can produce high process yields. The tofu industry itself plays a very important role in the Indonesian economy, due to its relatively large number.
As an alternative, Darminto offers the use of whey as a coagulant. “So far there is no model that can be directly applied to the tofu industry which uses whey as a coagulant. This model was developed based on a comprehensive study in the tofu industry,” he explained.
“MPV-Pro is a model that was developed based on a comprehensive study of all the dominant process variables that determine the yield of the tofu industry so that this model can be directly used to predict the yield of tofu and can also be simulated by adjusting the levels used on the process variables,” said the man who has served as the Dean of FTP UB.
MPV-Pro, he added, contributes to the development of knowledge, especially those related to improving existing processing processes in the tofu industry. “This model is more accurate in determining the yield because it is based on the dominant variables of the tofu industry, such as the type of soybean, the ratio between water and soybeans, pH and coagulant temperature, pH of the coagulaso process and intensity of coagulant addition and printing time.
“Even though it is a comprehensive model, this model still has weaknesses, especially if the variable rate used is outside the predetermined range,” he concluded.
Darminto is the 10th professor from the Faculty of Agricultural Technology. He is also the 177th and 330th active professor of all professors at Universitas Brawijaya.
Prof. Dr. Eng. Denny Widhiyanuriyawan
Prof. Dr. Eng. Denny Widhiyanuriyawan, S.T., M.T. gave a scientific oration entitled “Remote Sensing Technology for Harvesting New and Renewable Energy”.
In his research, Prof. Deny is trying to explore satellite data to map the potential for New and Renewable Energy (EBT) in Indonesia such as wind and provide alternative energy conversion machines that are in accordance with the existing potential.
Based on the results of the study done by Prof. Deny, remote sensing from the QuikScat satellite, the potential for wind energy in Indonesian waters and WindSat in several areas of southern Sumatra, southern Java, and southern Papua has a potential speed of 6-12 m/s. and Power Density shows the excellent category.
However, other waters show low wind speeds of 3-6 m/s with the Power Density category in the marginal and good categories.
QuikScat and WindSat satellite data for 11 years is used to map the potential of wind energy. Processing of satellite data using filling-gap and smoothing methods shows that most areas of Indonesia have wind speeds of 3-6 m/s with marginal to good power density, so that the Savonius vertical shaft turbine is suitable for the development in Indonesia.
Meanwhile, the Savonius Mill has the advantage of being able to work at low wind speeds but with an efficiency of 15%.
Prof. Dr. Eng. Nurkholis Hamidi, ST, M.Eng
Prof. Nurkholis was inaugurated as a professor in the field of New Renewable Energy Biofuels introducing the Use of Fame Catalytic Cracking and E-CNT Additives to Improve Biodiesel Quality.
For a long time, the world’s energy sources have been dominated by fossil fuels. However, this energy source contributes to environmental problems and depleting supplies. Scientific research innovations in the field of biofuel-based renewable energy have been carried out. The newest of this innovation is the application of FAME catalytic cracking technology and E-CNT additive to improve the physical properties and combustion characteristics of Fatty Acid Methyl Ester (FAME) biodiesel fuel.
Indonesia itself has succeeded in increasing the utilization of biodiesel in the form of Fatty Acid Methyl Ester (FAME) since the implementation of the mandatory B20 program in 2016 to B30 in 2020. Indonesia is also a tropical country with large tracts of land and various varieties of plants that have the potential to produce vegetable oil to be processed into biodiesel in very large quantities.
The physical properties of biodiesel oil, especially its viscosity and evaporation properties, can be improved by breaking the chain of its compounds. Currently, we are trying to apply FAME catalytic cracking technology to improve the physical properties of biodiesel oil. This technology is a catalytic cracking technology or the cracking of biodiesel oil with the help of an H-zeolite catalyst. The catalytic cracking process is capable of breaking down long carbon chains into shorter hydrocarbon chains. With the formation of short carbon chains, it is expected to improve some of the physical properties of biodiesel fuel.
According to Nurkholis, innovations related to E-CNT additives for biodiesel can still be developed even better. “So that FAME biodiesel fuel can be applied to diesel engines with high concentration levels or in a pure state. Innovations related to the E-CNT additive for biodiesel need to be tested directly in its use in diesel engines,” he said.
Catalytic cracking innovation can be developed from the catalyst and process side so that it can become part of the process in making biodiesel which will produce quality fuel according to engine standards and can be developed into a tool that can be applied in the fuel system and combustion of diesel vehicles to improve the engine combustion process to be more effective and efficient.
Nurkholis is the 20th active professor in the Faculty of Engineering. He was inaugurated as a professor in the field of new renewable energy biofuels and became the 179th active professor at Universitas Brawijaya and became the 333rd professor produced by Universitas Brawijaya. [UB PR/ Trans. Iir]
