Abstract

Abstract: Soil is an important part of a sub-building structure, soil characteristics need to be considered in the initial planning of a construction, in order to achieve stability and security for the building above it. With different soil conditions, as is the case with the soil in Ngasem village which has low carrying capacity, it is necessary to know which structure meets the requirements for the soil conditions in Ngasem. To find out the characteristics of the soil is done by testing in the laboratory, namely testing the physical and mechanical properties. Testing the physical properties of the soil is testing the water content (Wc), specific gravity (Gs), Atterberg limits and soil unit weight (γ). Mechanical testing with proctor test and direct shear strength. The method used is an experimental method by taking soil samples at a depth of ± 80 cm and conducting research tests in the Kadiri University laboratory. So that the results of soil classification with the SW-SM code are obtained which are classified as well-graded sandy soils with silt mixtures based on USCS and classified as (A-1-b) according to the AASHTO classification system. The Atterberg Limit of Low Plasticity (clay low plasticity) with a Plastic Index Value of 3.243 which is classified as Slightly Plastic, a shear angle value of 38.748° with a cohesion value of 1.914, a maximum dry unit weight value of 1.77 gr/cm3 , and an optimum moisture content of 14.44 . So that with this study, the community is expected to choose and adjust the type and quality of the structure of building materials in accordance with the state of the land.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas metode Real-Time Kinematic (RTK) dalam meningkatkan efisiensi waktu dan akurasi survei lapangan pada proyek penanganan jalan longsor di RSP Nawacita, Long Pahangai, Mahakam Ulu. Metode konvensional seperti Total Station, meskipun akurat, dinilai kurang efisien karena memerlukan waktu dan tenaga lebih besar, terutama di medan yang sulit. Penelitian menggunakan pendekatan deskriptif kuantitatif dengan membandingkan waktu pengambilan data antara RTK dan metode konvensional. Hasil menunjukkan bahwa RTK mampu mengurangi waktu survei hingga 70%, dengan rata-rata 3 menit per titik dibandingkan 10 menit pada metode konvensional. Akurasi RTK mencapai ±1,5 cm (horizontal) dan ±3,2 cm (vertikal), yang masih memenuhi toleransi teknis untuk survei jalan. Selain itu, penggunaan RTK berdampak positif pada manajemen waktu proyek dan pengurangan biaya operasional hingga 25%. Kendala seperti gangguan sinyal dan cuaca dapat diatasi dengan strategi penempatan base station dan penjadwalan ulang. Temuan ini merekomendasikan penerapan RTK pada proyek infrastruktur dengan medan menantang serta penyusunan SOP untuk optimalisasi hasil. Penelitian selanjutnya dapat mengintegrasikan RTK dengan teknologi UAV atau BIM untuk peningkatan efisiensi lebih lanjut.
