Abstract

AbstrakPermasalahan lalu lintas merupakan salah satu konsekuensi dari rendahnya kesadaran pengguna jalan dalam menaati aturan yang berlaku. Untuk itu, pentingnya dilaksanakan kegiatan sosialisasi kepada masyarakat sebagai bentuk pengendalian non-fisik, dengan tujuan untuk meningkatkan kesadaran dan pemahaman masyarakat mengenai keselamatan berlalu lintas secara menyeluruh. Pelaksanaan kegiatan ini dilakukan pada Senin tanggal 26 Mei 2025 di Aula Kantor Desa Lembar Selatan dan dihadiri oleh 32 orang peserta, terdiri dari perangkat desa, kepala dusun dan perwakilan karang taruna yang ada di Desa Lembar Selatan yang juga bertindak sebagai mitra kegiatan ini. Metode pelaksanaan kegiatan ini terdiri dari empat tahapan yaitu tahap persiapan, tahap sosialisasi, tahap diskusi, serta tahap evaluasi dan monitoring. Kegiatan sosialisasi ini telah terlaksana dengan baik dan mendapat tanggapan positif dari peserta. Materi yang disampaikan dinilai bermanfaat, informatif, dan mampu meningkatkan kesadaran akan pentingnya mematuhi peraturan lalu lintas demi keselamatan diri sendiri maupun orang lain. Kata kunci: lalu lintas; sosialisasi; keselamatan. AbstractTraffic problems are one of the consequences of low awareness of road users in obeying applicable regulations. For this reason, it is important to carry out socialization activities to the community as a form of non-physical control, with the aim of increasing public awareness and understanding of traffic safety as a whole. The implementation of this activity was carried out on Monday, May 26, 2025 at the Lembar Selatan Village Office Hall and was attended by 32 participants, consisting of village officials, hamlet heads and representatives of youth organizations in Lembar Selatan Village who also acted as partners in this activity. The method of implementing this activity consists of four stages, namely the preparation stage, the socialization stage, the discussion stage, and the evaluation and monitoring stage. This socialization activity has been carried out well and received a positive response from the participants. The material presented was considered useful, informative, and able to increase awareness of the importance of obeying traffic regulations for the safety of oneself and others. Keywords: traffic; socialization; safety.

Abstract

Spun pile foundations were used in the construction of the Mayor's Office Building in Jempong Village, Mataram City, West Nusa Tenggara Province, as elements that transfer structural loads to more stable soil. This study aims to analyze the bearing capacity of spun pile foundations manually to obtain the ultimate bearing capacity and allowable bearing capacity values by comparing the Luciano Decourt and Tomlinson methods based on SPT data. Through this analysis, it is hoped that the most efficient and appropriate method for application in the soil conditions in the area can be determined. Based on the calculation results, the Luciano Decourt method produced a bearing capacity and allowable bearing capacity of 137,344 tons and 54,938 tons, respectively, while the Tomlinson method produced a bearing capacity and allowable bearing capacity of 89,489 tons and 35,795 tons, respectively. It can be concluded that the most efficient and appropriate method to use in pile foundation planning for the soil conditions in the area is the Tomlinson method because it produces a more conservative bearing capacity. The use of this conservative bearing capacity can help avoid the risk of foundation failure.

Abstract

The construction of the Mataram Mayor's Office requires pile foundations with adequate bearing capacity to support the building load and improve the quality of public services. This study analyzes the bearing capacity of pile foundations based on SPT test data using several calculation methods, and compares them with the results of the PDA dynamic test. By comparing several bearing capacity calculation methods, this study aims to identify the level of accuracy and deviation of theoretical estimation results from actual conditions in the field. The research method used is quantitative analysis by utilizing Standard Penetration Test (SPT) test data as the basis for calculating the bearing capacity of pile foundations using several empirical methods, namely the O'Neil & Reese, Luciano Decourt, and Briaud et al. The results show that the bearing capacity values of pile foundations calculated based on SPT test data using various empirical methods differ from the results of the PDA dynamic test, but are still within a technically acceptable range. These differences are influenced by soil characteristics and the assumptions of each method, so that certain methods tend to show results that are closer to actual conditions in the field. Pile foundation planning relies not only on theoretical calculations based on SPT data but also combines them with PDA dynamic test results to improve the accuracy and reliability of the foundation design. Furthermore, the choice of bearing capacity calculation method must be adapted to local soil conditions to ensure more representative and safe planning results.

Abstract

The Mataram Mayor's Building, West Nusa Tenggara, consists of 3 floors with a total height of 14.25 m. All floors of the building use reinforced concrete structures, which make them vulnerable to lateral forces, especially those caused by earthquakes. Earthquakes risk causing building damage, therefore a special frame-bearing structure is needed to withstand earthquake forces to prevent structural failure, therefore shear walls are needed to withstand lateral forces. The placement and shape of shear walls affect the building's ability to withstand lateral forces. The problem of researchers in this study is how to compare the effectiveness of the four variations of shear walls when resisting lateral forces. So that researchers get the goal of knowing the value of floor deviations in the x and y directions and knowing the optimal placement location point in resisting lateral forces. In this study, a general type of data collection method is used, namely data collection carried out by collecting working drawings from project service providers. Based on the results of the analysis of the four existing models, it can be concluded that the placement of the shear wall position is more effective if placed at the right corner of the L-shaped building, if viewed from the results of the floor deviation values in the x and y directions. Where the overall floor deviation in the x direction of variation 1 is 1.12 mm, while the deviation in the y direction is 2.80 mm.
