Abstract

Pembangunan sarana transportasi darat dalam hal ini jalan raya di Kabupaten Pulau Morotai saat ini sudah sangat pesat. Salah satu ruas jalan yang direncanakan untuk pembangunan jalan baru yaitu Ruas Jalan Kampus Unipas Morotai. Sejauh ini pembangunan jalan baru di Kabupaten Pulau Morotai dalam perencanaannya belum secara maksimal dilakukan survey untuk menguji kondisi tanah dasar maupun kekuatan tanah dasarnya. Tujuan penelitian ini adalah untuk mengetahui daya dukung tanah dasar (subgrade) untuk keperluan perencanaan tebal perkerasan jalan di ruas jalan kampus Unipas Morotai melalui pengujian secara langsung di lapangan dengan pengujian laboratorium.Hasil penelitian menunjukkan bahwa jenis tanah pada 3 titik lokasi pengambilan sampel termasuk jenis Tanah Lempung dengan kadar air lapangan tinggi antara 30-35%. Nilai CBR laboratorium pada titik 01 sebesar 33%, titik 2 sebesar 28% dan titik 3 sebesar 49%. Hasil ini menunjukan bahwa dari hasil pengujian lab, tanah dasar memnuhi syarat sebagai subgrade pada perkerasan jalan dimana CBR >5%. Nilai CBR lapangan yang diuji pada titik 6 titik pengujian memberikan nilai yang variatif  sebesar 4,64%-6,96% Hasil ini menunjukan bahwa dari hasil pengujian lab, tanah dasar memnuhi syarat sebagai subgrade pada perkerasan jalan dimana CBR >5% pada titik 01, dan titik 04. Sedangkan pada 4 titik lainnya tidak memenuhi nilai CBR nya sehingga diperlukan pemadatan khusus dilpangan.

Abstract

The development of land transportation, in this case the highway in Morotai Island Regency, is currently very fast. One of the roads planned for the construction of a new road is the Unipas Morotai Campus Road Section. So far, the construction of new roads in Morotai Island Regency has not been optimally carried out by a survey to test the condition of the subgrade and the strength of the base soil. The purpose of this study was to determine the carrying capacity of the subgrade for the purpose of planning pavement thickness on the Unipas Morotai campus road through direct field testing with laboratory testing. The results showed that the soil types in the 3 sampling locations were loamy soils with high water content in the field between 30-35%. The laboratory CBR value at point 01 is 33%, point 2 is 28% and point 3 is 49%. These results indicate that from the results of laboratory testing, subgrade fulfills the requirements as a subgrade on road pavement where CBR> 5%. The CBR value of the field tested at point 6 test points gave a varied value of 4.64% -6.96%. These results indicate that from the lab test results, subgrade fulfills the requirements as a subgrade on the pavement where CBR> 5% at point 01 , and point 04. Meanwhile, the other 4 points did not meet their CBR values so that special compaction was needed in the field..
