Sebagai negara kepulauan yang tempat tinggal penduduknya tersebar di banyak pulau, keberadaan TIK untuk pendidikan mutlak diperlukan. Untuk kepentingan tersebut Pusat Teknologi Informasi dan Komunikasi (Pustekkom) diberi amanah untuk mengelola dan mengkoordinasikan pemanfaatan TIK untuk pendidikan. Sejak tahun 2008 Pustekkom telah memberikan fasilitas TIK untuk pembelajaran yang berupa bandwidth gratis melalui Jejaring Pendidikan Nasional (jardiknas) kepada lebih dari 16.000 sekolah SD, SMP, SMA dan SMK di Indonesia, dan secara bertahap memberikan pelatihan bagi para guru di sekolah tersebut dalam memanfaatkan TIK untuk pembelajaran. Masalahnya “apakah fasilitas TIK dan pelatihan guru tersebut memberikan kontribusi terhadap peningkatan nilai UN SMP dan SMA khususnya di Propinsi Maluku. Untuk menjawab pertanyaan ini, dilakukan penelitian dengan cara membandingkan nilai UN pada pereode sebelum diberikan fasilitas TIK yaitu tahun 2005-2007 dengan pereode setelah diberikan fasilitas TIK, yakni tahun 2008-2011. Pengambilan sampel dilakukan dengan menggunakan teknik proportional stratified random sampling. Perbedaan rerata dari hasil UN antara sebelum dengan sesudah diberikan fasilitas TIK diuji melalui Uji-t dengan menggunakan taraf signifikansi 0,05. Hasil penelitian menunjukkan bahwa terdapat peningkatan nilai UN yang signifikan untuk seluruh mata pelajaran yang di UN-kan. Peningkatan nilai UN diduga karena pengaruh TIK dan pelatihan guru dalam pemanfaatan TIK untuk pembelajaran. Dari hasil penelitian ini disarankan agar pemerintah secara terus menerus meningkatkan pemberian layanan TIK ke sekolah-sekolah lainnya di Indonesia, sekaligus memberikan pelatihan pemanfaatan TIK untuk pembelajaran kepada guru-gurunya. As an archipelagic country, where people live in many islands, the presence of ICT for education is absolutely necessary. For this purposes, The state of Republic Indonesia through the Ministry of Education and Culture was given the mandate to The Center of ICT for Education (Pustekkom) to manage and coordinate the using of ICT for education. Due to, since 2008 Pustekkom has provided ICT facilities (in the form of free bandwidth) via the National Education Network (Jardiknas) program to more than 16,000 schools: Secondary School (SC), Senior High School (SHC) and Vocational School (VC) especially in Maluku Province , and gradually trained teachers in schools in the using of ICT for learning. The problem is “whether ICT facilities and teacher training contributed to an increase in the National Examination value of SC and SHC”. To answer this question, the research done by comparing the value on before being awarded the ICT facilities in the years of 2005-2007 period with after being given of the ICT facilities, the years of 2008-2011 period. Sampling was done using proportional stratified random sampling technique. The difference of between average the period tested by t-test using the significance level of 0.05. The results showed that there were significant increasing the value of the National Examination for all subjects tested. Increasing the value of National Examination allegedly under the influence of ICT facilities and teacher training in the using ICT forlearning. From the results of this study suggested that the government is continuously improving ICT services to all schoolin Indonesia and providing training to teachers on ICT for education/learning.
