In an effort to support the paperless program, utilization of technology for Attitude Competency Assessment in 2013 curriculum is needed, so there needs to be a system that can facilitate the assessment process of attitude competency that is more concise, efficient and Paperless. In this study there are 3 (three) methods used: Observation, library study, and prototyping. The results of this research in the form of prototype input competency assessment of social and spiritual attitude is packaged in the form of questionnaire, which is expected to assist in the processing of assessment data.

This research is an effective digital certificate publishing activity by utilizing blockchain technology. By implementing decentralized systems and cryptography owned by the blockchain, it will potentially enlarge the educational progress space in Indonesia. The weakness of the current running system, lies in the difficulty of identifying the validity of a certificate issued by an educational institution. Therefore, the advantages that blockchain has, able to assist an educational institution, in establishing a widely accessible certification system infrastructure, to support the transparency and accountability of an educational institution, in identifying the validity of the certificate. Blockcert as one of MIT's tools, while acting as a barometer, is used to perform a series of activities in publishing activities and the implementation of official documents that are designed based on a technology commonly referred to as Blockchain. The research conducted will demonstrate that a decentralized consensus will be able to provide good distribution of information that can include all certificate deployment activities.

Ijazah merupakan tanda bukti atau suatu dokumen pengakuan atas selesainya jenjang pendidikan yang telah ditempuh seorang pelajar. Keberadaan Ijazah tentu sangat bernilai penting karena digunakan sebagai alat dalam melakukan berbagai kegiatan diantaranya sebagai dokumen dalam melamar kerja. Pada studi lapangan banyak ditemukan suatu pelanggaran hukum yakni, kasus pemalsuan ijazah untuk tujuan mendapatkan pekerjaan yang layak. Kendati ijazah sangat mudah dipalsukan, hal ini menyebabkan sulitnya memastikan keabsahan dari dokumen tersebut. Hadirnya teknologi blockchain di era 4.0 ini diharapkan mampu dimanfaatkan dalam dunia pendidikan dengan menerapkan keunggulan yang dimiliki oleh blockchain yaitu sistem terdesentralisasi dan kriptografi, maka keberadaan teknologi blockchain akan mampu mengeliminasi keberadaan ijazah palsu dan mampu membuktikan keabsahan ijazah bagi calon pelamar kerja, secara efektif, efisien serta transparan. Penelitian ini mengadopsi 2 metode yaitu, metode analisis deskriptif dan metode studi pustaka. Blockchain diharapkan mampu ikut menyumbang keberhasilan dan meningkatkan kualitas pendidikan nasional.
