Abstract

Most buildings have spaces far from the windows that require artificial lighting for illumination throughout the day. In fact, artificial lighting contributes to the second highest electrical energy consumption, especially in educational institutions that require more lighting. One of the appropriate solutions to illuminate areas far from windows is using a fiber optic daylighting system. FOD is used to distribute sunlight into the spaces away from the window. This research tested the lighting levels produced by alternative collector and diffuser models of FOD systems to meet the lighting level standards (lux) in discussion room P. 06. 05. Petra Christian University. This research uses experimental methods under actual weather exposure and simulation with DIALux software. Simulation results show that the room requires 6 collectors and 2 diffusers, arranged centrally and symmetrically. It produces 365 lux and a uniformity ratio of 0.59, which meets the standard. The lighting level data used was at 10:30 AM during partially cloudy conditions.

Abstract

Design activities in a studio do not only involve students, but also need to be accompanied by tutors, guest lecturers, consumers, and the professionals. Each of these individuals gives different contribution according to each own competency. The involvement that takes place between these individuals does not only consist of tutorials, and is not just an activity in which "the student asks and the tutor answers". The involvement consists of various programs, which must be arranged and coordinated inside a tight schedule. This wrong image of studio instruction has been prevalent, and this seems to be caused by the practice of tutors of treating their students not as students whom they are educating and instructing, but more as junior designers who are working in a design project. The activities of the students and tutors in the studio then are just training and not teaching while in reality both of them are absolutely necessary in studio instruction. Abstract in Bahasa Indonesia : Aktivitas kerja desain di sebuah studio jurusan aritektur melibatkan tidak hanya mahasiswa, tetapi membutuhkan kehadiran pembimbing, dosen tamu, calon pengguna, dan professional (baca: praktisi). Setiap individu yang terlibat mempunyai peran yang berbeda-beda sesuai kompetensinya, sedangkan keterlibatan antar individu tidak sekedar dilakukan dengan cara asistensi. Aktivitas di studio bukanlah sekedar aktivitas "mahasiswa bertanya dan pembimbing menjawab", melainkan terdiri dari bermacam-macam program aktivitas yang harus didisain dengan penjadwalan waktu yang ketat. Image belajar di studio selama ini lebih pada kebiasaan pembimbing memperlakukan mahasiswa bukan sebagai anak didiknya, tetapi sebagai junior arhitect dalam menyelesaikan desain sebuah proyek. Aktivitas yang dilakukan oleh mahasiswa dan pembimbing di studio hanyalah sekedar pelatihan (training) dan bukan pengajaran (teaching), padahal kedua-duanya mutlak diperlukan dan diwadahi pada sebuah studio desain. Kata kunci: Manajemen studio, studio fisik, pengajaran disain di studio.

Abstract

Noise from the road exceeding 40 dB disturbs the room atmosphere and quality of rest in an apartment. The aim of this research will utilize the wind to swing the kinetic facade to create background noise that supports the user's well-being. The aim of this research is to invent a kinetic façade system that supports the apartment user's well-being. To achieve this, the research utilizes wind to blow kinetic facades to produce background noise which also reduces glare from sunlight thereby improving well-being. Experiments were carried out by comparing the results of measuring frequencies of bamboo musical instruments with solfeggio frequencies. The bamboo musical instruments analyzed included 18 angklungs, 3 windchimes and 21 variations of bamboo models. The frequencies obtained by the final model are close to that of solfeggio frequencies, namely 432Hz, 639Hz, 747Hz and 852 Hz. This can reduce Daylight Glare Probability (DGP) by 13.36%, 9.69%, and 5.01%.

Abstract

Reducing CO2 emission through innovation discovery is essential to respond to the global warming issue. The research states that construction material contributes 11% of CO2 emission on building. Agricultural waste in Indonesia is plentiful, but it has not been used optimally, one of examples is corncob waste. The study to theoretically identify the absorption level on acoustic panel of corncob waste using two kinds of panel thickness dimensions composed of natural corncob through literature study and laboratory test of impedance tube by identifying the absorption panel coefficient phenomenon of corncob waste. The physical characteristic of corncob is porous, and this study found that there was a good absorption level in two dimensions of panel thickness of 3 cm and 5 cm. It was strengthened by the finding of a frequency shift phenomenon of two dimensions of panel thickness due to resonance in air cavity/gap among corncobs.
