Abstract

Maps are complex data sets containing information on the location and objects of an area. Maps can show the distribution of various things on Earth, such as settlement patterns, mountains and others. ArcGIS is software that can be used in making village maps. Air Merah village is a village in Curup Tengah sub-district, Bengkulu, which until now has not had complete mapping for the area. The purpose of this service is to help present village data that can be accessed as spatial data information in planning development progress in Air Merah Village. Community service is carried out in stages of visiting the village head's office for administrative processes, conducting discussions with the team, collecting data through field surveys and interviews, making maps, and discussing the results of thematic maps, as well as holding a presentation to discuss the results of the map and handing over map printouts to village officials. This service activity was attended by lecturers, partners and students who were involved in all series of services both in the field and discussions, so as to produce village information maps. Based on the results of field surveys and modeling, Air Merah Village has an area of ± 10.7789 km2 and is located at latitude longitude -3.4801, 102.556365. Map making has received a positive response from the surrounding community and is expected to be able to provide location information and improve the inventory of Air Merah Village.

Abstract

ABSTRACT Lubuk Mumpo village is planned to build a bridge connecting the 2 villages. The construction of the bridge is planned to use precast pile foundations with a diameter of 40 cm. The bearing capacity value of the pile foundation needs to be known for construction planning. Therefore, testing the bearing capacity of pile foundations needs to be carried out before construction begins. The research was carried out with the aim of knowing the comparison of the bearing capacity values ​​of pile foundations using sondir and laboratory data. In this research, the method used is an approach to the results of the physical and mechanical properties of the soil and an experimental method. The results of the research that has been carried out show that the value of the bearing capacity of the pile foundation in laboratory data has a more stable value compared to using sondir data, with the value of the bearing capacity of the pile foundation on soil A being 1817.969 tonnes using sondir data and 2027.4 tons using lab data. On land B the total value was 1565.555 tonnes while laboratory data was 2021.18 tonnes. The difference in the values ​​obtained is caused by the different coefficient values ​​used for each method. This research was carried out to help determine a more accurate method for calculating bearing capacity, so that foundation design can be optimized for cost efficiency and structural safety.  Keywords: Bridge, Bearing Capacity, Sondir   ABSTRAK Desa Lubuk Mumpo direncanakan membangun suatu jembatan yang menghubungkan antara 2 (dua) desa. Pembangunan jembatan direncanakan menggunakan pondasi tiang pancang pracetak berdiameter 40 cm. Nilai daya dukung pondasi tiang pancang perlu diketahui untuk perencanaan konstruksi. Oleh sebab itu pengujian daya dukung pondasi tiang pancang perlu dilakukan sebelum suatu konstruksi dimulai. Penelitian dilakukan dengan tujuan untuk mengetahui perbandingan nilai daya dukung pondasi tiang pancang dengan menggunakan data sondir dan laboratorium. Pada penelitian ini metode yang digunakan adalah metode pendekatan hasil sifat fisik serta mekanis tanah dan metode eksperimental. Hasil dari penelitian yang telah dilakukan didapat bahwa nilai daya dukung pondasi tiang pancang pada data laboratorium memiliki nilai yang lebih stabil dibanding dengan menggunakan data sondir, dengan nilai daya dukung pondasi tiang pancang pada tanah A 1817,969 ton dengan menggunakan data sondir dan 2027,4 ton menggunakan data lab. Pada tanah B total nilai sebesar 1565,555 ton sedangkan data laboratorium 2021,18 ton. Perbedaan nilai yang diapat ini disebabkan oleh nilai koefisen yang digunakan berbeda setiap metode. Penelitian ini dilakukan agar dapat membantu dalam menentukan metode yang lebih akurat untuk perhitungan daya dukung, sehingga desain pondasi dapat dioptimalkan untuk efisiensi biaya dan keamanan struktural.  Kata Kunci: Jembatan, Daya Dukung, Sondir
