Landscape Geometry-based Percolation of Traffic in Several Populous Cities around the World
Fisca Dian Utami, Dui Yanto Rahman, Desyana Olenka Margaretta +2
We described the average traffic congestion in several populous cities around the world from a new concept, namely landscape percolation. The ratio of the residential area size to…
Experiment and Modeling of Rice Winnowing: Granular Segregation Method in Ancient Traditions
Rahmawati Munir, Handika Dany Rahmayanti, Riri Murniati +3
Rice winnowing is a process of separation of small and large rice grains by air flow practiced since the ancient human history especially in societies where rice is the main source…
Brazil Nut Effect in Roads that Allow Cars and Motorbikes to Pass Through
Fisca Dian Utami, Desyana Olenka Margaretta, Donny Dwiputra +3
In some countries, cars and motorbikes are allowed to pass through the same road. We observe a phenomenon similar to a Brazil nut effect (BNE) that frequently occurs on such roads,…
Very high efficiency of low cost graphite-based solar cell by improving the fill factor using optimal ion concentration in polymer electrolyte
Dui Yanto Rahman, Fisca Dian Utami, Asep Ridwan Setiawan +2
We report the development of graphite-based solar cells using a simple method and low cost materials. Suspension of graphite powder in mineral water was simply dropped onto the sur…
New Design of Potentially Low-cost Solar Cells Using TiO2/Graphite Composite as Photon Absorber
Dui Yanto Rahman, Mamat Rokhmat, Elfi Yuliza +2
A solar cell design using the combination of titanium dioxide and graphite as active photon absorbing materials were proposed. The titanium dioxide absorbs photons of nearly ultrav…
