I'm a mechanical engineering student of the 8th semester at Universitas Indonesia Faculty of Engineering's International Program. I love engineering topics such as renewable energy, automotive, and aviation. Aside from that, I'm passionate about geopolitics, social issues, and history.

In accordance to my engineering passion in the subjects previously mentioned, I plan to concentrate on aerodynamics, aeronautics, and control systems for my thesis and for my postgraduate studies.


Today I'm feeling energized to start the new semester.

About justice, what I feel constitute as 'justice' is the equity of opportunity available for those who are willing to go after and grab those opportunities. For example, free education, cross-subsidy, or an upside down tax-strata are some of the ways the government can help manifest the coveted equal opportunity for their citizens, by way of helping those who are in need to catch up to their more fortunate counterpart in terms of education, economy, etc.

In an engineering sense, equal opportunity can be brought into the scene by developing and integrating low-cost technologies which can be implemented in remote areas. These technologies may include simple electricity generator such as rudimentary water and wind turbines, clean water piping system, telecommunication grid expansion, etc. These technologies, if implemented correctly, these can help people who are living in said areas in, for example, studying in the night, or have wider access to information.

Fluid mechanics in my opinion is one of the pillars of mechanical engineering, in addition to manufacturing methods and design. Many topics such as pipe engineering, aerodynamics, pneumatics, etc. have a very tight relationship with fluid mechanics.

Energy is the capacity for an object to do work upon another object. Wherupon asked by a child to explain the concept of energy, in my opinion you can say something along the lines of "how heavy an object can you lift? How far can you run? Can you go through your activities without feeling hungry?", etc.

The equation "U = Q + W" signifies that for a change in energy within a system, there must be heat either going in or out to the system, and work done to or by the system. This can be related to our daily activity, especially studying, that in order to gain 'energy' (knowledge), we must let ourselves absorb 'energy' around us and do work to gain that 'energy'.


Yesterday Pak Dai told us to try to understand the following block diagram from Open Modelica:


This diagram is used to represent the core of the workings of a combined cycle powerplant, where the plant essentially increases its efficiency by using leftover heat from one cycle to the other. At this point of the course, I still do not know which cycle is used in this particular case of power plant.
