Balai Padang Adat is one of the traditional building in tropical area. The characteristic of this building is large, long and deep dimention but it has limited area of the openings. Field meassurement for 3 days and 3 times (09.00, 12.00, 15.00) is used to identify factors that affect daylighting performance. This research found that daylighting performance was in poor quality. The outdoor illumination is very high which reached 100.000 lux caused by latitude, altitude and cloud cover. The latitude is 2o in the south from the equator’s line and the altitude is 450 meters above sea level which close from the sun. The cloud cover is minimum lower than 40%. The indoor illumination can reach 1 lux as the lowest level during the day caused by obstruction, overhang, shape and space of the building, material reflectance, area and position of the openings. There is a building in the west and east and a vegetation in the south as an obstruction. This building has a large dimention with double layer room, but it has minimum material reflectance of the wall and floor. This building has a minimum area of the openings, high position of the openings near the overhangs and also long dimention of the overhang. Meassurement was done in Laras-Pematang room as a living room and Bilik room as a bedroom and kitchen. Overall, daylighting performance of this building can not meet standart activity such as illumination value, daylighting factors and daylighting distribution from morning to the evening.

Keamanan lingkungan menjadi kebutuhan mendasar untuk menciptakan suasana kerja yang kondusif dan sebagai upaya untuk menjaga segala aset atau sumber daya dalam suatu organisasi. Semakin tinggi tingkat keamanan suatu lingkungan akan semakin rendah risiko kerugian akibat kehilangan aset atau bahaya yang mengancam personil. Petugas kemanan dalam suatu lingkungan kerja menjadi salah satu tumpuan untuk melaksanakan fungsi-fungsi pengamanan dan penyelamatan. Secara rutin dan berlanjut, petugas keamanan melakukan kegiatan monitoring terhadap aset-aset internal dan pemeriksaan lalu lintas kendaraan dan orang yang masuk serta keluar lingkungan. Perhitungan jumlah petugas keamanan perlu mempertimbangkan target tingkat keamanan lingkungan, cakupan luas area pengamanan, volume dan frekuensi kendaraan/orang/aset/perangkat yang harus diamati atau diperiksa. Penentuan jumlah petugas keamanan yang diperlukan untuk memenuhi standar minimal keamanan. Simulasi proses pemeriksaaan surat kendaraan pada pos keamanan dikembangkan dalam penelitian ini untuk mengukur beban kerja petugas keamanan. Jumlah petugas keamanan yang dipertimbangkan dalam simulasi adalah 1 petugas, 2 petugas dan 3 petugas. Sedangkan tingkat pengamanan yang diperhitungkan adalah pada tingkat 100%, 90%, 80%, 70%, dan 50%. Berdasarkan pola data kedatangan kendaraan dan pola waktu siklus pemeriksaan surat kendaraan, penelitian ini dapat menggambarkan beban kerja petugas keamanan terhadap tingkat keamanan yang ingin diterapkan. Untuk menerapkan tingkat pengamanan maksimal yaitu 100%, diperlukan 3 orang petugas keamanan pada tiap pos. Dengan jumlah petugas keamanan sebanyak 2 orang, kondisi beban kerja normal dapat dicapai dengan tingkat keamanan 90%. Namun dengan 1 orang petugas keamanan, tingkat keamanan yang dapat dicapai akan kurang dari 50%.

The improvement in smartphone technology has encouraged the exploration in field of user experience. The internal inertial navigation system sensors of a smartphone enables it to infer the its three dimensional indoor orientation and position when it is being pointed at certain objects by hand. However, the sensors’ flawed measurements complicate estimation of position and orientation precisely. Previous studies shows that sensor fusion of both internal and external measurements can enhanced the performance. However, those estimations didn’t cover the pointer-like usage. To achieve the possibility of smartphone as pointer, the estimation using sensor fusion has been performed. Unfortunately, these experiments resulted in bad position estimation for small precision, while the orientation estimation was passable
