State high school SMAN 1 Semarang has rented a power generator to ensure that students run computer-based national exams not disrupted by power outages over the next four days.

The school's vice principal, Agustin Yuanis, said Monday that the school spent Rp 6 million to rent the generator for four days.

“We received the funding from the students’ parents. We had to do this in order to avoid complications during the national exam,” Agustin said.

Agustin said the Central Java Education Agency had coordinated with state-owned electricity company PLN to inspect the school's electrical system. However, the school decided to rent the power generator because of the recent unpredictable weather conditions.

The principal of private high school Pangudi Luhur Don Bosco, Bruder Agustinus Sudarmadi, said his school was not worried about the possibility of electrical failures as his school already had their own power generator.

At least 11 of 48 vocational high schools in Kendal regency, Central Java, experienced power outages during the computer-based national exam last week. Heavy rainfall had caused several trees to fall, which disrupted electricity lines. (rdi/wit)
