Aerodynamics has a major influence on vehicles moving at a certain speed. Aerodynamics is influenced by the form factor and air flow that comes in contact directly on the surface of the vehicle, causing obstacles and flow separations that occur in the rear of the vehicle that affect the stability of the vehicle. Obstacles that occur significantly affect vehicle fuel consumption. Thus the pu…
Through data released by BPS and UNESCO, the index of reading interest in Indonesian society is still categorized as low. Yet through the development of technology, reading activities can be done more easily. And one of the platforms that facilitate this reading activity is Wattpad. Wattpad is a website service and smart phone application, which allows users to read or submit work in the form o…
Palm Oil Mill Effluent (POME) has organic matter content and high pollutant load, therefore it requires many ponds and long times to treatment. The microalgae consortia is able to utilize organic material as a source of nutrition for its growth, therefore may reduce pollutant, time, and amount of the pond in POME treatment. This research used a microalgae consortia from POME. The aim of this re…
Energy use mostly comes from non-renewable energy sources that gradually decreased. Biofuel production from microalgae consortium can be one of the alternative energies in producing renewable energy. Lipid content in the biomass of a microalgae consortium can be converted into biofuel raw materials. The organic material contained in Palm Oil Mill Effluent (POME) can be a nutrient source fo…
