Abstract

The background of this research is as an effort to determine the level of accuracy in the Compass Solution and Trimble Business Center software. So that you can find software with a better level of accuracy. The purpose of this study is to find out the results of processing static observation data using Compass Solution and Trimble Business Center software to obtain a report on the processing results in the form of point coordinate values. The methods used in measurement activities are absolute and differential methods which are then processed using Compas Solution Software and Trimble Business Center software. The results obtained in this study are the availability of the difference in coordinates X, Y and Z when processing using Compass Solution and Trimble Business Center software. The results of differential method data processing using the Trimbel Business Center application (strategy 3) are closest to the fixed BM coordinate values ​​that have been determined, namely with an average difference in the X value of 7.75 mm, Y value of 17.5 mm, and the average difference The Z value is 266.25 mm. Meanwhile, the results of absolute method data processing using the Compass Solution application (strategy 2) are closest to the fixed BM coordinate values, namely with an average difference in the X value of 1,129 mm, Y value of 229.25 mm, and an average difference in Z value is 1,131 mm.

Abstract

The background of this research is due to the efforts to repair roads in Kutai Barat Regency, which are unevenly distributed. As a result, there are still many damaged road sections, including the Samarinda - Melak main road, thus necessitating a road condition assessment. The purpose of this research is to map the damage level of the Samarinda - Melak axis road. This research requires understanding in the field of geomatics to carry out measurement and mapping activities. The method used in the measurement activities is the tachimetry method which is then processed using Autocad Civil 3D, while checking road conditions is carried out directly at the measurement location. The results obtained in this study are a map of road damage, cross-sectional maps, and the level of road damage. The results show that the classification of damage on the Samarinda - Melak main road includes potholes, stripping, and distortion. Along the Samarinda - Melak main road, it can be observed that 57% of road damage is classified as potholes, 23% as distortion, and 20% as stripping.

Abstract

This study aims to compare and evaluate the accuracy of land area measurement through aerial photo identification with direct field/ terestrial measurements using Geodetic GPS. This is useful for determining the most efficient and accurate method to support the acceleration of the Complete Systematic Land Registration (PTSL) program. Based on the measurement activities and data analysis, the largest coordinate discrepancy between aerial photo identification and direct measurement using Geodetic GPS was found in land parcel 10, with a difference of 0.88031550. The smallest discrepancy was observed in land parcel 7, with a difference of 0.06694568. The total coordinate discrepancy across the measurement of 10 land parcels was 3.92, with an average discrepancy of 0.35. The Root Mean Square Error (RMSE) value was 0.59. Furthermore, the field measurement results showed that direct field measurement using Geodetic GPS produced highly accurate land area data. The discrepancy between the land area proposed by the applicant and the direct measurement results had an average difference of only 0.7 m². Meanwhile, the measurement results of land area through aerial photo identification showed a larger average discrepancy compared to the land area proposed by PTSL applicants, with an average difference of 10.8 m².

Abstract

The spatial pattern mapping in village areas plays a crucial role in sustainable village planning and development. The objective of this study is to produce a spatial pattern map of Bunga Jadi Village, located in Muara Kaman Sub-district, Kutai Kartanegara Regency, and to identify the distribution of spatial patterns within the village. The results of the spatial pattern mapping in Bunga Jadi Village indicate that the protected area covers 1,106.72 hectares, or approximately 21.04% of the total area, while the cultivation area covers 4,152.62 hectares, or around 78.96% of the total area. The functional classification of areas in Bunga Jadi Village includes forest areas, peatland forests, green open spaces (RTH), business/trade and service areas, mining areas, and the most prominent potential area in the village, which is the plantation area, with a total area of 5,259.34 hectares.

Abstract

The GNSS survey method is currently widely used for various purposes, both scientific and practical, due to its advantages in terms of accuracy, speed, simplicity, and lower cost. Today, a wide range of GNSS survey instruments are available for benchmark point observations. Therefore, it is necessary to obtain information regarding the accuracy that these different instruments can provide. This study compares the results of benchmark point observations using the same method, namely the static method, but with two different instruments: Spectra SP80 and Comnav T300. The aim of this research is to determine the accuracy level of benchmark observations using the Spectra SP80 and Comnav T300, processed with the Trimble Business Center application. The comparative analysis shows that the Spectra SP80, when processed using Trimble Business Center, produces a smaller average difference in X and Y coordinates compared to the Comnav T300. However, in the Z coordinate, the Comnav T300 shows a smaller average difference than the Spectra SP80. Data analysis from the processing summary images provides information on the precision levels of both instruments. At benchmark point BM 2, the Comnav T300 demonstrated superior horizontal and vertical precision compared to the Spectra SP80. Conversely, at benchmark point BM 5, the Spectra SP80 showed better horizontal and vertical precision than the Comnav T300.

Abstract

Landslides are one of the most frequent and destructive natural disasters in West Java Province, particularly in Bandung City, which is characterized by varied topography, high rainfall, and rapid land-use change. This study aims to analyze and map the spatial distribution of landslide susceptibility in Bandung City using the Weighted Overlay method based on Geographic Information Systems (GIS). Five parameters were applied in the analysis: slope, rainfall intensity, soil type, rock type, and land use. Each parameter was classified and weighted according to its influence on landslide occurrence. The analysis revealed that the landslide susceptibility levels in Bandung vary from low to very high. The largest area, covering 49.88%, falls within the moderate susceptibility class, while 36.02% of the area is categorized as high to very high susceptibility. High rainfall intensity and extensive land-use conversion in hilly regions were identified as the dominant contributing factors to landslide potential, supported by steep slopes and easily weathered geological formations. The resulting susceptibility map provides essential spatial information for local government authorities in developing sustainable land-use planning, risk mitigation strategies, and community preparedness programs. The study highlights the effectiveness of GIS-based analysis for environmental hazard assessment and emphasizes the need for high-resolution data integration in future research to improve mapping accuracy.
