iukur menggunakan alat vicat. data dianalisis menggunakan uji kruskall-wallis dan dilanjutkan dengan uji mann-whitney. berdasarkan hasil uji statistik kruskall-wallis menunjukkan terdapat hubungan berat bubuk semen portland aceh tipe 1 terhadap setting time. pada hasil uji lanjutan mann-whitney menunjukkan terdapat perbedaan nilai setting time yang signifikan berbeda antara tiap kelompok perlakuan. kesimpulan dari penelitian ini adalah setiap rasio kelompok berat bubuk semen portland aceh tipe 1 memiliki setting time yang lebih lama dibandingkan dengan semen mta kedokteran gigi sehingga material ini tidak dapat dijadikan sebagai alternatif semen mta. kata kunci: semen portland, mineral trioxide aggregate, setting time. abstract name : nanda aulia rahmah study program : dentistry faculty : dentistry title : comparative study of type 1 aceh portland cement powder weight as an alternative to dental mineral trioxide aggregate (from setting time perspective) portland cement is construction cement that containing certain chemical compounds similar to the cement used in dentistry named mineral trioxide aggregate (mta). mineral trioxide aggregate cement was manipulated using 100 grams of powder and 30 ml of distilled water. as the wated mixed with the cement powder, hydration occur and reaction produce a mixture of cement that harden and solidify. the purpose of this study was identify and obtain data on which of type 1 aceh portland cement powder weight ratio best used as an alternative mta cement in the terms of setting time. twenty four speciments were divided into six treatment groups. the setting time was measured by vicat devide. data were analyzed by kruskall-walis test followed by mann-whitney test. the statistical result of kruskall-wallis test showed that was a correlation of type 1 aceh portland cement powder weight to setting time. the result of mann-whitney test showed significant differences of setting time between each treatment group. in summary, each group ratio of type 1 aceh portland cement powder has longer setting time compared to mta therefore the material can not be used as an alternative to mta dental cement. keywords: portland cement, mineral trioxide aggregate, setting
