Abstract

In the field of construction, particularly in geotechnical engineering, uncertainties in foundation design approaches are frequently encountered. Geotechnical uncertainties, especially in foundation design, pose complex challenges due to the heterogeneous nature of soil and data limitations. Dynamic load testing on pile foundations is an alternative method to static load testing in geotechnical engineering for evaluating pile capacity and behavior. The results of this analysis will be compared to the design capacity of pile foundations in the breasting dolphin structure. This study on a breasting dolphin structure utilizing Steel Pipe Pile (SPP) foundations with a diameter 610 mm. PDA tests were conducted on piles at points G6-23, G7-33, G7-38, and G8-46. The study begins with a literature review to comprehend methods and theories related to pile capacity analysis based on calendaring and PDA testing. Calendaring data were analyzed using empirical methods such as the Hiley Formula to estimate the dynamic bearing capacity of each pile. The pile capacity calculated using the Hiley Formula is generally higher than the results obtained from the Case Method and CAPWAP Analysis. The relationship between pile capacity based on the Hiley Formula (calendaring) and the Case Method (PDA test) yielded a linear regression equation of y = 1.0785x - 983.07 with R² = 0.2385, indicating a weak correlation. Meanwhile, the relationship between pile capacity from the Hiley Formula (calendaring) and CAPWAP Analysis (PDA test) resulted in a linear regression equation of y = -0.006x + 2909.8 with R² = 1×10?¹, indicating almost no linear correlation between the two.

Abstract

Bangunan gedung lantai 3 UTP Surakarta Kampus II dibangun sekitar tahun 1990an dengan material beton bertulang. Bangunan gedung bertingkat ini berlokasi di jalan Walanda Maramis No.31, Nusukan, Kec. Banjarsari, Kota Surakarta. Gedung ini berfungsi sebagai tempat perkuliahan pada lantai 1 dan 2, serta ruang olahraga pada lantai 3. Dalam proses perencanaan bangunan gedung, perhitungan struktur menjadi salah satu elemen kunci yang tak dapat diabaikan. Dokumen perhitungan struktur merupakan rangkaian detail yang menjelaskan analisis dan perhitungan teknis terhadap kekuatan dan stabilitas suatu struktur bangunan. Dokumen teknis bangunan gedung lantai 3 UTP Surakarta perlu dibuat dalam upaya untuk menganalisis kekuatan struktur terhadap resiko bencana kegempaan saat ini. Asesmen bangunan gedung perlu dilakukan untuk menjadi pedoman dalam perencanaan dan perubahan fungsi bangunan yang mungkin dilakukan kedepannya. Berdasarkan permasalahan diatas, maka diusulkan kegiatan Pengabdian kepada Masyarakat dengan tema “Asesmen Mutu Beton Dan Tulangan Bangunan Gedung Perkuliahan 3 Lantai Kampus 2 UTP Surakarta”. Tahapan dan teknis pelaksanaan pengabdian msyarakat ini difokuskan pada kegiatan survey dan pengujian lapangan. Kegiatan survey dan pegujian lapangan sendiri terdiri dari beberapa tahap mulai dari persiapan, survey denah dan pelaksanaan pengujian lapangan. Hasil survei pada elemen stuktur beton bertulang menunjukkan kondisi yang masih baik dan tidak terjadi retak struktural. Hasil survei pada struktur atap baja, menunjukkan karat pada profile sturktur. Tetapi kondisi karat tidak mendegradasi penampang elemen yang dapat mengurangi kekuatan. Hasil destructive test yang dilakukan menunjukkan kuat tekan beton minimal sebesar 11.70 MPa dan terbesar 22.50 MPa.

Abstract

A drainage system is a series of activities designed to drain water from an area or area, including surface water and ground water. Drainage systems are also an important part of urban areas. A well-organized urban area must have a drainage system that functions well, so that it does not cause standing water which can disrupt community activities, especially those related to environmental health. On the Pengging-Banyudono road, Ngaru-ngaru Village, Banyudono District, Boyolali Regency, which is a residential area and sales kiosk, there are still several problems with the drainage system which is not functioning properly and must be addressed immediately. If the rainfall is high enough, it will cause water to pool on the body and shoulders of the road, which can cause water channels to become blocked and disrupt residents' activities. So it is necessary to evaluate drainage channels and handle waterlogging on Jalan Pengging-Banyudono, Boyolali Regency. This research aims to determine the existing drainage system and evaluate the capacity of the drainage channel. From monitoring, there is sedimentation, sedimentation and changes in the cross-sectional dimensions of the channel which trigger blockage of water flow. Meanwhile, the analysis results show that the channel capacity is unable to accommodate the existing flood discharge. In the existing channel, the channel discharge (Qs) is 0.0081m3/second, smaller than the 25 year flood discharge (0.2783 m3/second). This means that the existing channel capacity is not able to accommodate flood discharge. The results of calculating the dimensions of the new channel, obtained the most economical channel dimensions with a channel width of 1.2 m and a channel height of 1.2 m.

Abstract

Water availability is an aspect that should be given high priority by the government to meet community needs, both in urban and rural areas. Generally, the current water sources come from rivers, canals, or shallow groundwater wells. The water availability in irrigated land obtained from weirs is crucial for the agricultural sector. Dams have a role to hold water and distribute it through irrigation channels to agricultural land, in order to ensure consistent water availability, especially in the dry season. Tritis Dam functions to raise the elevation of the river water level so that it can be used to irrigate into irrigation channels. Tritis weir is a permanent dam with a stone masonry structure located in Sambirejo Village, Sambirejo District, Sragen Regency, which is located in the Tritis Watershed with an area of ??31.15 km2. The purpose of this study is to determine planned flood discharge value. The method used in this study is the Synthetic Unit Hydrograph (HSS) ITB-I, but previously it must process GPM (Global Precipitation Measurement) satellite rainfall data and calculate the planned rainfall using the Log Pearson III frequency distribution method. The planned flood discharge in the Tritis Watershed, Sragen Regency using the HSS ITB I method was obtained at 258.41 m3/second for a 50-year return period and 318.09 m3/second for a 100-year return period.

Abstract

This study aims to characterize the effect of superplasticizer addition on local aggregate concrete workability and early-age compressive strength. The methodology involved the use of Portland Composite Cement, local fine and coarse aggregates, and Fosroc Auracast SP310 superplasticizer at dosages of 1%, 1.6%, and 2%. Four concrete mix designs were prepared: normal concrete (BN) and concrete with superplasticizer additions (BN-1%, BN-1.6%, BN-2%). Slump and compressive strength tests were conducted according to Indonesian standards to assess workability and strength at 7 and 14 days. Results indicate that superplasticizer addition significantly improves concrete workability with slump values ranging from 560 to 630 mm compared to 115 mm for the control. Compressive strength also increased markedly, with BN-2% showing the highest strength at 38.56 MPa at 7 days and 51.94 MPa at 14 days. The study concludes that superplasticizer effectively enhances both workability and compressive strength without increasing water demand, resulting in denser and stronger concrete at early curing ages.

Abstract

Perancangan desain ruang publik di Desa Pereng, Kabupaten Karanganyar, dilakukan sebagai respons terhadap kebutuhan masyarakat akan ruang terbuka yang multifungsi, nyaman, dan aman. Pemilihan topik ini penting mengingat minimnya fasilitas publik yang mampu mendukung interaksi sosial, rekreasi, serta pengembangan ekonomi lokal. Metode pengabdian masyarakat yang digunakan adalah perancangan arsitektural yang melibatkan survei kebutuhan masyarakat, analisis lokasi, dan penyusunan konsep desain yang inklusif serta berkelanjutan. Hasil pengabdian menunjukkan terciptanya ruang publik yang mengintegrasikan fasilitas olahraga, taman bermain anak, serta kios UMKM yang dapat meningkatkan kualitas hidup dan daya tarik ekonomi desa. Ruang publik ini diharapkan menjadi pusat aktivitas sosial dan ekonomi yang berkontribusi pada pemberdayaan masyarakat. Kesimpulannya, perancangan ini memberikan solusi konkret dalam pemanfaatan ruang terbuka yang adaptif terhadap kebutuhan masyarakat Desa Pereng, sekaligus menjadi model pengembangan public space yang dapat direplikasi pada wilayah lain.
