Abstract

Gunung Sari Village, Batu City is a hilly mountainous area. Where the elevation contour of the land is at an altitude of ± 800 meters above sea level. Because of its hilly location, there are many steep slopes around the location. These slopes have the potential to experience landslides, considering that the rainfall in these locations is very high. Potential slopes with such conditions are suspected to have a safety factor (SF) < 1. For this reason, researchers are interested in analyzing the slopes on these slopes using the limit equilibrium method. In this study the method that will be used is to analyze the factor of safety in the existing conditions and the factor of safety after the slope is given geotextile reinforcement which will be modeled with the Geoslope/W 2012 application. The results of the safety factor analysis of existing conditions at cross 1 using the Geo Slope/W 2012 Program, the Bishop method, is 0.851, while for the Morgenstern method it is 0.961. Both methods show a safety factor value of less than 1 (F<1), which means the slope is unstable and has a high potential for landslides. The value of the safety factor with geotextile reinforcement for both methods has increased, making the slope more stable (F>1). The safety factor value for cross 1 of the Bishop method is 1.698 while for the Morgenstern method it is 1.702.

Abstract

The management of zakat, infaq, and sadaqah (ZIS) funds in many mosques is still carried out conventionally, leading to inefficiencies in collection, reporting, and distribution, as well as limited transparency and accountability. Masjid Raya An-Nur at Politeknik Negeri Malang, as a religious activity center, plays a strategic role in managing community funds. However, its manual system has hindered timely financial recording and reporting. The main challenges include limited access for donors to contribute online, slow verification processes, and a lack of transparency that may reduce public trust. To address these issues, this community service program developed and implemented an Android-based mobile application for ZIS management. The methodology involved a needs analysis through interviews and observations, system design utilizing REST API architecture with a Laravel back-end and MySQL database, and user training for both administrators and donors. The results indicate that the application successfully facilitates online donations, provides real-time reporting, and enhances donor participation through transparency features and digital reminders. Furthermore, the payment gateway integration enables more flexible and secure payment methods. Overall, the system has improved the efficiency, transparency, and accountability of ZIS management at Masjid Raya An-Nur, strengthened donor trust, and contributed to the digital transformation of religious social fund governance.

Abstract

This thesis evaluates the horizontal coefficient of consolidation (Ch) in a soft soil improvement project using Prefabricated Vertical Drains (PVD) and preloading at Cluster F, Summarecon Bandung. The area consists of soft clay with high compressibility and low shear strength, requiring ground improvement for safe construction. The study compares the assumed Ch value used in design with the actual Ch obtained from field monitoring. The design Ch was derived from laboratory consolidation tests and applied using Barron’s radial consolidation theory. Settlement plate data collected during preloading was analyzed with the Asaoka method to calculate the actual Ch. Results show a clear discrepancy: the assumed Ch of 2.93 × 10⁻⁴ m²/s was significantly higher than the actual Ch of 1.60 × 10⁻⁴ m²/s, a deviation of -45%. This indicates that relying solely on laboratory values can lead to overly optimistic settlement predictions. Using the actual Ch in revised analysis produced more realistic results. The study highlights the importance of validating design parameters with field data, as back-calculation from monitoring provides better insight into soil behavior, reduces construction risks, and leads to more reliable ground improvement designs.

Abstract

This research investigates the discrepancy between theoretical and actual field settlement in soft clay soils, using the Plaza Summarecon Bandung project as a case study. Soil improvement techniques involving preloading and the installation of Prefabricated Vertical Drains (PVD) and Prefabricated Horizontal Drains (PHD) were applied to accelerate consolidation and enhance soil stability. The objective of this study is to compare theoretical settlement calculations with actual field measurements, identify contributing factors to discrepancies, and propose refinements to the theoretical models. The research method involves collecting soil investigation data, field monitoring data (Settlement Plates), and project construction documentation. Theoretical settlement was calculated using Terzaghi’s one-dimensional consolidation theory and extended with Barron and Hansbo's PVD acceleration models. Field settlement data were analyzed over time to create settlement curves and evaluate actual behavior during the preloading period. Findings show that actual settlement significantly deviates from theoretical predictions. The settlement prediction accuracy for Settlement Plate (SP) 1 is 25.43%, SP-2 is 46.97%, and SP-3 is 94.40%. The deviation is primarily due to incomplete soil investigation data, omission of construction and indirect loads in theoretical models, and inconsistencies in field monitoring. Additionally, differences in PVD patterns (triangular vs. square) affected the time to 90% consolidation, with triangular layouts achieving faster results due to better service area coverage. This study concludes that theoretical models can be refined by incorporating site-specific factors, adhering to standard soil investigation protocols, and improving field monitoring practices. It emphasizes the importance of accurate modeling and continuous instrumentation for ensuring reliable ground improvement in soft soil areas.
