This study aims to determine the value of aluminum specific resistance which is calculated based on Ohm's law. This research uses an experimental method. In this study, 4 experiments were carried out with different lengths of wire. The first experiment used a wire length of 0.05 m, the second experiment used a wire length of 0.1 m, the third experiment used a wire length of 0.15 m, and the fourth experiment used a wire length of 0.2 m. The results of the study showed that the wire length of 0.05 m obtained the value of the type resistance of 2.7 x 10-3 Ωm, the length of the wire of 0.1 m obtained the value of the type resistance of 2.7 x 10-3 Ωm, the length wire of 0.15 m obtained type resistance value of 2.7 x 10-3 Ωm and at a wire length of 0.2 m obtained type resistance value of 2.7 x 10-3 Ωm. Thus, it can be concluded that the change value of aluminum types will be the same value if the wire material used is also the same value.

Management of educational facilities and infrastructure can be interpreted as utilising all existing components related to educational facilities and infrastructure in schools in supporting the educational process. This study describes the management of educational facilities and infrastructure supporting student learning activities in SMA Nagan Raya Regency. The method used is a descriptive analysis method with a qualitative approach -data collection techniques through observation, interviews, and documentation studies. The research subjects are the Principal, Vice Principal for Facilities and Infrastructure, and Teachers. The results showed that: 1) educational facilities and infrastructure planning is carried out during meetings involving the principal, viceprincipals, and all teachers related to the school's needs in supporting student learning activities. 2) Procurement of educational facilities and infrastructure is carried out by considering the current needs at the school and adjusting to the available budget. If the procurement can be fulfilled with the BOS budget, then the procurement is done with the available BOS budget. 3) The inventory of educational facilities and infrastructure is adjusted to the condition of the facilities and infrastructure available at the school. 4) The school's needs carry out the distribution and utilisation of educational facilities and infrastructure. 5) Maintenance of educational facilities and infrastructure begins with checking the facilities and infrastructure available at the school. 6) Eliminating educational facilities and infrastructure in schools has never been implemented.
