Salah satu teknologi upaya yang mampu mendukung pengembangan green building adalah penerapan teknologi plumbing. Plumbing mampu mendukung upaya konservasi air, sehingga dapat meminimalisir penggunaan air bersih yang tidak perlu dari kebutuhan air dalam gedung. Tujuan penelitian ini adalah untuk mengetahui seberapa jauh kajian penelitian mengenai plumbing yang telah dikaji, termasuk kaitannya dengan green building. Penelitian ini menggunakan metode literatur review berdasarkan pendekatan bibliometrik. Data dikumpulkan menggunakan aplikasi Publish or Perish (PoP) dan dianalisis menggunakan software VOSviewer untuk memvisualisasikan peta jaringan interaktif dan menganalisis data bibliometrik. Berdasarkan hasil visualisasi jaringan, penelitian terkait plumbing system memiliki hubungan yang kuat dengan implementation, water, use, system, building, plumbing, green building, energy, green building rating system, dan bim. Hasil visualisasi overlay plumbing system dan green building rating system, keduanya termasuk penelitian-penelitian terbaru yang saat ini banyak diteliti/dikaji. Green building dan building memiliki tingkat kepadatan yang tinggi dibandingkan topik penelitian lain disekitarnya. Secara keseluruhan, penelitian mengenai plumbing kaitannya dengan green bulding masih tergolong sedikit namun populer beberapa tahun terakhir, sehingga penelitian ini perlu dikaji lebih dalam lagi dan disesuaikan dengan standar perencanaan plumbing dan green bulding di setiap negara. 2024-07-26T00:00:00Z http://hdl.handle.net/123456789/56279 Perbandingan fondasi tiang bor dengan tiang pancang pada abutmen jembatan (studi kasus: Jembatan Surah) Aulia, Siti Nur; Suharyatma; Amalina, Anisa Nur; Artati, Hanindya Kusuma The ongoing toll road development is the Solo - Yogyakarta - NYIA Kulon Progo Toll Road Project which aims to reduce congestion on the main roads and support economic improvement in an area, especially Central Java and DI Yogyakarta. In this project several connecting bridges were built to avoid rivers and cultural heritage, one of which is the Surah Bridge. In supporting a bridge, a bridge foundation is needed which functions to distribute the load from the overlying structure to the supporting soil layer below without a decrease in the structural system. This research was conducted on the Solo-Yogya-NYIA Kulon Progo Toll Road Project Section 1 Package 1.1 Solo-Klaten, specifically on the Surah Bridge STA 12+195 using secondary data from PT Adhi Karya (Persero) Tbk. This study aims to determine the weight of the load acting on the bridge, the bearing capacity, and the foundation that is more effectively and efficiently used in receiving the loading of the Surah Bridge. The results obtained from this study are the loading on the Surah Bridge with a vertical load of 6776,29 tons. The bearing capacity (Qall) of the Drill Pile based on the Reese & Wright Method is 589.37 Tons and the Skempton Method is 476.55 Tons. The bearing capacity (Qall) of the Pile based on the U.S. Army Corps Method is 439.64 Tons and the Tomlinson Method is 630.10 Tons. The more effective and efficient foundation used on the Surah Bridge is the pile foundation using the calculation of the Tomlinson Method because the number of pile uses can be minimized. 2024-07-26T00:00:00Z http://hdl.handle.net/123456789/56278 Pengaruh penggunaan semen dan Rotec terhadap parameter kuat geser tanah lanau dengan uji triaxial Rani, Masyhta Syah; Amalina, Anisa Nur; Fajarwati, Yuli Selecting the right type of soil is very important in building construction planning to ensure stability and adequate bearing capacity. High- plasticity (MH) silt soils can expand when wet and contract when dry, which can cause soil settlement and damage to structures above them. This research aims to determine the effect of adding cement and Rotec as stabilizing materials on shear strength parameters. The tests carried out are in the form of soil property tests and Triaxial UU (Unconsolidated Undrained) tests. The results of this research show that the test soil is categorized as elastic silt soil (silt with sand) based on the USCS classification and soil with moderate to poor properties based on the AASHTO classification. Based on UU Triaxial testing, the cohesion value (c) of the original soil was found to be 0.655 kg/cm2 with an internal friction angle (φ) of 28.080o. The largest cohesion value (c) is found in the variation of adding 1% Rotec + 1.5% cement for 14 days of curing, namely 0.811 kg/cm2 with an internal shear angle (φ) value of 32.639°. This shows that the use of cement and Rotec can increase soil shear strength parameters. 2024-07-26T00:00:00Z http://hdl.handle.net/123456789/56277 Evaluasi daya dukung aksial pondasi tiang pancang pada tanah lempung di Jakarta Timur Hidayat, Muhammad Zakki Rizal; Marasabessy, Muhammad Irfan; Alhamid, Muhamad Fadlan; Rohman, Wahyu Nur; Putri, Mayangsari Rafiqa; Hanafi, Nufrizal Faried This study evaluates the axial bearing capacity of pile foundations on clay soil in Cakung, East Jakarta, a region with complex soil conditions for construction. The research involves collecting field data using a Hydraulic Static Pile Driver (HSPD) to measure hydraulic pressure during pile installation and analyzing data from Standard Penetration Tests (SPT) and Pile Driving Analyzer (PDA) tests. Results show significant variations in bearing capacity at different depths, ranging from 8 to 12 meters. Pile points near BH-04 and BH-03 faced difficulties reaching 12 meters depth as the soil bearing capacity exceeded the HSPD capacity before this depth. A substantial increase in post-installation bearing capacity was observed through PDA tests, with an increase of 79.19 tons at grid A-5 after 19 days. This increase is due to augmented friction over time, as shown by CAPWAP analysis in the PDA tests. There is a strong correlation between HSPD manometer data and undrained shear strength (Cu), with a determination coefficient (R2) of 0.8286. Using HSPD manometer data for evaluating bearing capacity provides more accurate and consistent results compared to conventional methods relying solely on soil investigation data. Additionally, the use of HSPD in pile installation offers better control over pile positioning and depth, while reducing vibration and noise impacts, making it suitable for densely populated urban areas. PDA tests validate HSPD data, demonstrating significant post-installation capacity increases, crucial for ensuring structural safety and stability. 2024-07-26T00:00:00Z
