Abstract

The selection of the appropriate drilling method is crucial, especially for offshore projects (conducted on rivers or seas), which generally involve deep drilling lengths and large diameters. One drilling method, aside from the commonly used “Kelly bar system” for land drilling, is the circulation system. For the “Approach Bridge” and “Main Bridge” sections of the Suramadu Bridge, the drilling method employed was the “Circulation” method. The focus of this discussion is on the “Approach Bridge” section, as the drilling depth reaches around 80-90 meters, and the soil conditions are quite varied according to available data. However, in general, clay shale layers were found, a type of soil highly sensitive to disturbances during the drilling process and to weather effects. Therefore, during the drilling process, a slurry stabilizer is required to prevent the collapse of the bore pile walls. The slurry stabilizer used involves mud and bentonite. After the bore pile construction is completed, the piles will be tested to determine their bearing capacity. The bore pile tests are conducted using the Osterberg Cell method, and a Sonic Logging test is also carried out to assess the integrity of the bore piles.

Abstract

Kelurahan Setia Mekar in Kabupaten Bekasi is experiencing rapid development in economic and infrastructure aspects, which results in an increase in the need for space for social and religious activities. Jami' An-Nur Mosque, as a center for religious activities, facing limited space to accommodate zakat activities, infaq and alms. To solve this problem, it is planned to build Baitul Maal near the mosque. This project involved the Community Service team from the Architecture Study Program of Pelita Bangsa University who designed the architectural plans for Baitul Maal An-Nur. The method used includes Focus Group Discussion (FGD), Function Identification, Site Analysis, environmentally friendly, inclusive and sustainable architectural design planning. The results achieved include building designs that are efficient, accessible and meet the needs of the local community. This program provides a sustainable solution for managing zakat and religious activities and becomes a model for community and academic collaboration in developing social infrastructure.

Abstract

This community service project aims to redesign and expand Masjid Jami’ An-Nur located in Papan Mas Housing, Setia Mekar Village, by integrating sustainable architectural principles. The mosque faces issues of limited prayer space and supporting facilities, insufficient natural ventilation and lighting, and the absence of dedicated rooms for the Quranic Education Center (TPQ) and mosque administrators. This program applied a Participatory Action Research (PAR) approach through stages of socialization, field survey, needs analysis, design development, design presentation, evaluation, and revision. The project resulted in a conceptual mosque design that is adaptive, energy-efficient, and environmentally friendly. Proposed solutions include adding a TPQ room with a 30-student capacity, a management and storage room, implementing cross-ventilation and natural openings to enhance thermal comfort, and maximizing daylighting to potentially reduce electricity use by up to 20%. This design not only fulfills worship and educational space needs but also strengthens the mosque’s socio-religious role and raises environmental awareness within the community. The project supports the implementation of the Merdeka Belajar Kampus Merdeka (MBKM) program and Higher Education Key Performance Indicators (IKU) by demonstrating a tangible contribution of universities to society through sustainable architecture.

Abstract

In Pekalongan City, particularly on Perintis Kemerdekaan Street and Patriot Street, waterlogging frequently occurs during the rainy season due to ineffective drainage systems. The main causes are narrowed drainage channels, sediment buildup, waste accumulation, and wastewater discharge from nearby residential areas. These streets are vital access points to offices, schools, and trade centers, making the waterlogging a significant disruption to economic activities and the community. According to the analysis, the peak discharge on Perintis Kemerdekaan Street for a 5-year period is 24.305 m³/s, while the channel's capacity is only 18.869 m³/s. On Patriot Street, the peak discharge is 3.575 m³/s, with a channel capacity of 46.427 m³/s. Although the drainage capacity in both locations is adequate to accommodate the peak discharge, waterlogging still occurs due to external factors such as sediment and waste clogging the drains, along with heavy rainfall.
