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.

Abstract

This research was conducted to find out the Body Condition Score (BCS, in nine scale) of 30 Limousine crossbred cows in Balongpanggang, Gresik regency at the time of  Artificial Insemination,  21 and 60 days later. Questionnaires obtained to identify the knowledge of farmers and inseminators in estrous detection. Conception Rate (CR) and Service per Conception (S/C) counted based on pregnancy diagnosis through rectal palpation 60 days post insemination. The result showed that the average of BCS in pregnant cows at 60 days post insemination was highest compared to the others. Conception rate and service per conception of the cows were 60% and 1.63 respectively, meanwhile the knowledge of estrous detection of farmers was lower compared to those of inseminator. It could be concluded that implementation of AI technique in Limousine crossbred cows at Balongpanggang, Gresik regency was good enough, but the knowledge of farmers about estrous detection needs to be improved.
