Research on the design and analysis of coils with geometry of square with sides of 12cm x12cm and the number of windings which varies namely 50, 150, and 300. The value of the magnetic induction generated by the coils was measured using a magnetic probe Pasco 2162 PS.- The value of the magnetic induction was measured as a function of distance, current, and the number of windings and then record…
Activated carbon had been made from sugar cane bagasse by pre-carbonization and chemical activation using ZnCl2 activator supported with microwave irradiation . Microwave irradiation time variated for 10 minutes, 15 minutes and 20 minutes. The purpose of the research to be cognizant of irradiation microwave time for activated carbon to evaluate adsorption of Pb, Fe, and Cu. Activated carbon wer…
Metamaterial simulation computationally is practice way for observing metamaterial which commonly achieves new metamaterial structures. This research investigates hexagonal-shaped metamaterial with gap and concentric double ring resonator, namely split ring resonator hexagonal-shaped (SRR-H). SRR-H metamaterial is optical metamaterial observing for frequency of 1 to 120 GHz. The simulation resu…

Indonesia is an anthropological country of 500 ethnic group language and culture features. Even more unique, earch of ethnic group has its own country of origin, historical experience and ancestry. In the countryside generates a variety of tradition that are very important and meaningful, but the villagers take the tradition as a regular thing that they routinely do and become something very va…
Fiber coupler was successfully developed by combining single mode fiber and fiber Bragg grating. A characterization of fiber coupler was analyzed based on result simulation by using OptiGrating software with varying long gratings of 1×104????????????????, 2×104???????????? , 3×104????????????????, 4×104????????????????, 5×104????????????????, and 6×104???????????????? using transfer matri…
Name K.H. Bustani Qadri is very mashur for the people of Indragiri Hilir regency, as Ulama is a role model for the ummah. Even though he is gone, his name is still remembered for the people of Inhil. In his devotion in Indragiri Hilir has given birth to Qari and Qariah who have reached the National and International level in teaching the art of reading the Qur'an. Not only as a teacher of tajwi…
The measurement of the magnetic degree and magnetic susceptibility of iron sand as a function of depth in Arta and Kata beach Pariaman West Sumatera has been carried out. The sample was dried thoroughly before being processed by iron sand separator. Prior to magnetic measurement, it was preparared a solenoid of 400 turns with the length of 9,8 cm, and diameter of 2,7 cm. The total magnetic indu…
The research was conducted to determine the rate of decline in water level of cassava opaque by using biomass energy from palm fronds. Drying is done by using a drying chamber with a length of 130 cm, width 90 cm and high 120 cm. The drying chamber is formed in such a manner that is equipped with a chimney, two-level drying rack and 2 drums as heat sources. Drying heat sources derived from biom…
The term "fortress" reminds us of a context of defense and warfare, especially in the past. The castle belongs to a historic building because it reminds us of the Indonesian people's struggle against the colonials before independence. Fortresses in Indonesia are generally built during the Dutch colonial period. One of the fortress that still stands today is Dutch Fortress in Benteng Hulu Villag…
