UPH Celebrates International Day of Light 2018 through a Series of Workshops, Seminars, and Humanitarian Activities

The International Day of Light 2018 celebration in Univ. Pelita Harapan, Indonesia consists of a series of activities under a big theme of “Lucis pro Nobis”, a Latin for “Light for Us”. The activities were organized by Electrical Engineering Student Union under its yearly event called as Electro Mega Project (EMP). The activities in UPH were endorsed by IEEE Indonesia Section, OSA Indonesia Section, and The Indonesian Optical Society.

The activities started at 18 May 2018 by delivering 3 parallel workshops in Poris Indah Junior (SMP Poris Indah) and Senior High Schools (SMA Poris Indah), Tangerang. For the 1st year middle school students, workshop on “Learning Optics through Experiments” were delivered by Julinda Pangaribuan, a lecturer of EE UPH. In this workshop the youths were amazed by seeing the world differently through an own-made kaleidoscope constructed of pieces of broken compact disks arranged in a tube taken from used toilet paper roll. Through this activity, the students learned about reflection and diffraction of light. The second workshop was “Fun with Optics” for last year middle school students, where using simple off-the-shelf stuffs from local DIY store and laser pointer, Marincan Pardede, a lecturer of EE UPH showed the geometrical optics principles of lenses using an own-made smoke-box, how rainbow happens through dispersion and multiple reflection visualized by laser light reflection in water inside a beaker glass, how reddish sky during sunset and sunrise happens by scattering of white light in water added with few drops of milk. The third workshop was “Make Your Own Solar Lamp” for senior high school students, delivered by Henri Uranus, a lecturer of EE UPH. In this workshop students learn on harvesting electricity from sun light using small solar panel and construct their own circuit to control battery charging and automatic night-on lamp. The unique aspect is that the lamp bulb is made of used mineral water bottle.

Additionally, a workshop on making a blinking keychain were delivered by EE students on 31 May 2018 to their fellow students from other departments.

On 28 May 2018, a seminar entitled “Let There be Light: Lucis Pro Nobis” by Henri Uranus and on 4 June 2018 on “Laser Applications” by Marincan Pardede were organized for UPH students.

On 9 June, 2018 a group of EE UPH’s student led by Josavan Ezekhiel Taniara, erected 4 poles of village street light constructed using affordable materials for garbage sorter (in Bahasa Indonesia: “pemulung”) community in Trash Dump of Bintara, Bekasi.

These series of IDL2018 activities outreaches around 100 high school students, 100 UPH students, and the humanitarian activity reaches a community of around 200 families.
