Authentic factual model assessment limited testing of students at the Jakarta State University Geography Education. The factual model was improved to be retested. The hypothetical model was tested on 120 respondents in geography education students at Jakarta State University & Indonesian Education University. Data analysis used by path analysis, with the help of AMOS software program 5. The type of authentic assessment is positively related, namely the performance appraisal of tool use (0,36) and project assessment (0,24), which has a negative relationship namely attitude assessment (-0,13), presentation performance (-0,14), and portfolio assessment (-0,40).

Metodologi yang digunakan yaitu library research (penelitian kepustakaan). Hasil yang didapatkan yaitu, Aceh memiliki berbagai tipologi sumber daya air, Pertama, memiliki 14 CAT (Cekungan Air Tanah), ada yang skala kabupaten/Kota, skala lintas kabupaten/kota bahkan skala lintas provinsi. Kedua, memiliki 10 Sungai, 11 WS (Wilayah Sungai), 15 DAS (Daerah Aliran Sungai) dan 7 Danau. Berbagai sumber daya air tersebut yang dimanfaatkan oleh penduduk Aceh berjumlah 5.189.466 jiwa, dengan jumlah kepala rumah tangga (kepala keluarga) 1.231.058 KK, dan tingkat kepadatan penduduk 91 Jiwa/Km², sehingga dapat dipastikan dengan sumber daya air yang sangat melimpah, pasokan air yang dibutuhkan oleh masyarakat akan selalu tercukupi.
