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

Abstract

Environmental safety and order are important aspects of creating a harmonious and prosperous community life. Environmental Security Posts (Pos Kamling) play an important role as a community-based security system in maintaining order and preventing crime. However, residents in RT. 17, Sukamulya Village, Sematang Borang District, Palembang City are facing the problem of the increasing number of vehicle theft cases parked in their home yards. Therefore, this community service activity is carried out with the aim of designing and building a neighborhood watch post as a solution to improve environmental security. The methods used include field surveys, direct observation, and interviews with RT officials and local residents to collect relevant data and information. The results of this service include the preparation of Pos Kamling planning documents, including the calculation of the Budget Plan (RAB), as well as the physical construction of the post until it is ready for use. Beside being a security monitoring center, the neighborhood watch post also serves as a means of social interaction that can strengthen relationships between residents. A Pos Kamling management unit was established after the activity to carry out the patrol SOP, supply the duty schedule, oversee the fast reporting channel, and accept the transfer of DED, RAB, and SOP papers as operational instructions.

Abstract

Access to clean water in urban areas is generally higher than in rural areas. However, clean water services are not always optimal or in accordance with established standards. Fair water distribution is essential to ensure that clean water is provided to the community in line with the principles of quality, quantity, continuity, accessibility, and affordability, both from formal and informal sources, and for different community groups, including marginalized and low-income households. This study aims to examine community perceptions regarding the fairness of clean water service distribution in Lebak Siliwangi Village, Bandung City. A qualitative descriptive approach was employed, using data obtained through observations, interviews, and literature review. The findings reveal that significant gaps remain in water service distribution. Water source from Local Water Supply Utility (PDAM) generally provides better service but does not reach all community groups equally.  Meanwhile, informal sources cover wider areas but face persistent challenges related to quality, quantity, and continuity. Community perceptions indicate that tariffs in some areas are still considered disproportionate to service quality, particularly for households with greater water needs. These results suggest that optimizing distribution networks, monitoring water quality, improving infrastructure, and encouraging community participation are key strategies to ensure inclusive and equitable clean water services.

Abstract

Pure Lawele Asbuton is a local natural asphalt with a high bitumen content and significant potential as a sustainable alternative binder for road pavement applications. This study aims to evaluate the mechanistic performance of Stone Matrix Asphalt (SMA) mixtures incorporating Lawele Asbuton through resilient modulus and fatigue resistance testing. SMA mixtures containing Lawele Asbuton were compared with mixtures using conventional Pen 60/70 asphalt and polymer-modified asphalt Starbit E-55. All tests were conducted at the Optimum Asphalt Content (OAC) determined using the Marshall method. The results indicate that SMA mixtures with modified binders exhibit superior mechanistic performance compared to Pen 60/70 asphalt. The PMA 2% mixture achieved resilient modulus values of 578 MPa at 35°C and 198 MPa at 45°C, along with a fatigue life of 242,660 cycles at a strain level of ±400 µε, which is significantly higher than that of the Pen 60/70 mixture. These findings demonstrate that pure Lawele Asbuton (PMA 2%) has strong potential as a local alternative binder capable of enhancing the structural performance and fatigue resistance of SMA mixtures.
