Abstract

Pengukuran poligon merupakan metode pengukuran Kerangka Dasar Horisontal yang umum digunakan dalam survei dan pemetaan. Presisi dalam pengukuran poligon memiliki dampak signifikan terhadap akurasi data pengukuran yang dihasilkan. Robotic Total Station, sebagai perangkat modern yang digunakan dalam pengukuran, memberikan ketelitian yang tinggi. Penelitian ini bertujuan untuk menginvestigasi dan menganalisis kesalahan dalam pengukuran poligon yang dilakukan dengan menggunakan Robotic Total Station. Metode yang digunakan dalam pengolahan data poligon yaitu metode bowditch dan least square. Hasil dari penelitian ini memberikan informasi tentang faktor yang dapat menyebabkan kesalahan dalam pengukuran poligon, serta ketelitian dari pengukuran dengan Robotic Total Station. Penelitian ini menunjukkan bahwa nilai ellips kesalahan yang dihasilkan oleh alat Robotic Total Station sangat kecil, dengan tingkat ketelitiannya berada pada rentang 10⁻²⁰ dan 10⁻²¹. Selain itu, hasil penelitian menunjukkan bahwa ukuran ellips kesalahan meningkat seiring dengan bertambahnya jarak dari titik kontrol pengukuran, Sesuai dengan teori kesalahan pengukuran yang menyatakan bahwa kesalahan cenderung meningkat saat titik pengamatan berada lebih jauh dari titik kontrol pengukuran. Analisis terhadap selisih koordinat poligon antara metode bowditch dan metode least square menunjukkan rata-rata selisih koordinat easting sebesar 0,109 m dan northing sebesar 0,067 m

Polygon measurement is a method of measuring the horizontal framework commonly used in surveying and mapping. The precision of polygon measurements significantly impacts the accuracy of the resulting survey data. The Robotic Total Station, as a modern device used in measurements, provides high accuracy. This study aims to investigate and analyze errors in polygon measurements conducted using the Robotic Total Station. The methods used in processing polygon data are the Bowditch method and the least squares method. The results of this study provide information about the factors that can cause errors in polygon measurements and the precision of measurements using the Robotic Total Station. The research indicates that the error ellipse values produced by the Robotic Total Station are very small, with accuracy levels in the range of 10⁻²⁰ and 10⁻²¹. Additionally, the study shows that the size of the error ellipse increases with the distance from the control measurement point, in accordance with the measurement error theory which states that errors tend to increase as the observation point is farther from the control measurement point. The analysis of the coordinate differences in the polygon between the Bowditch method and the least squares method shows an average coordinate difference of 0.109 m in easting and 0.067 m in northing.
