Floods present significant challenges to urban areas globally, including Kota Singkawang in West Kalimantan, Indonesia, due to its susceptibility to seasonal monsoons. Mitigation efforts are crucial to protect lives, infrastructure, and sustainable development amidst urbanization and climate change. This research delves into flood risk reduction methods by integrating technical, economic, social, and environmental dimensions to aid policymakers and stakeholders in efficient resource allocation.This study aims to enhance flood resilience by identifying critical intervention areas through structured approaches, leveraging literature reviews, field surveys, and consultations with local authorities and communities. Prioritizing flood risk mitigation involves evaluating existing strategies and implementing structural measures like flood control buildings.The analysis findings indicate that the primary focus for mitigation efforts and flood risk reduction in Kota Singkawang should involve structural measures, specifically implementing flood control structures like polder systems and retention ponds to effectively address sea tides and heavy rainfall impacts. However, given the preliminary nature of this study, a more thorough investigation with comprehensive data is necessary to implement these structural technologies fully. This comprehensive analysis underscores the significance of comprehending flood risk complexities to formulate sustainable urban strategies in Kota Singkawang.

This paper focuses on the design of a reinforced concrete structure for an eight-story shopping building in Singkawang City, located in a low to moderate seismic area. The study integrates relevant design considerations in response to the region's seismic conditions. Through structural analysis, the building is categorized as seismic design category B due to moderate seismic risk, leading to the selection of an ordinary moment-resisting frame system compliant with SNI 1726:2019. Emphasis is placed on the importance of using such a system to enhance ductility and prevent brittleness during earthquakes.The research emphasizes the need to design structures capable of withstanding various loads, including dead, superimposed dead, live, wind, and earthquake loads, particularly in West Kalimantan, known for its historically low to moderate seismic activity. Recent earthquake records highlight the necessity of earthquake-resistant design for safety and durability. Structural analysis confirms the building's stability against seismic forces, with a modal participation ratio meeting SNI 1726:2019 requirements, indicating robust response under seismic loads.The study also assesses inter-story drift and P-Delta effects to ensure they meet allowable limits, which is crucial for preserving structural integrity and preventing post-earthquake instability. A detailed reinforcement design following SNI 2847:2019 enhances structural strength and durability, especially when under seismic loading. The foundation design uses tailored hollow spun piles to provide sufficient bearing capacity and stability. This approach demonstrates resilience against potential seismic events in low-to-moderate seismic regions, highlighting the importance of integrating seismic design principles and ductility considerations for effective earthquake hazard mitigation.

Alat uji lapangan Cone Penetration Test (CPT) yang biasa kita sebut sondir telah banyak digunakan di Indonesia. Namun penggunaan Cone Penetration Test dengan pengukuran air pori (CPTu) belum digunakan secara luas, karena itu penelitian ini akan dilakukan secara langsung di lapangan (in situ) menggunakan alat CPTu. Pengujian in-situ memiliki keunggulan antara lain parameter tanah yang diperoleh pada kondisi tegangan yang sesungguhnya di lapangan, data yang diperoleh bersifat kontinu sepanjang kedalaman dan dapat mengatasi masalah pengambilan sampel ataupun ketergangguan sampel. Lokasi penelitian berada pada kawasan Gedebage Bandung yang saat ini mengalami perkembangan yang luar biasa. Tanah pada kawasan tersebut merupakan tanah lunak yang pada umumnya memiliki kuat geser rendah. Penentuan kuat geser lempung (Su) merupakan rasio net cone resistance dan faktor konus (Nkt). Penelitian lebih mendalam terhadap koefisien Nkt dalam evaluasi kuat geser tanah lunak berdasarkan data hasil uji CPTu akan di verifikasi menggunakan uji laboratorium. Hasil penelitian menunjukkan koefisien Nkt yang sesuai untuk kawasan Gedebage adalah 13-15. Rentang parameter kuat geser hasil uji laboratorium dan hasil uji CPTu di lapangan adalah sebagai berikut: kedalaman 0-10m Su >25 kPa, kedalaman 10-25m Su berkisar 10 kPa dan kedalaman 25-31m Su >100 kPa.
锥入度试验（CPT）现场测试工具（我们通常称之为 sondir）已在印度尼西亚广泛使用。然而，使用锥入度测试和孔隙水测量（CPTu）还没有得到广泛应用，因此本研究将直接在现场（原位）使用 CPTu 工具进行测试。原位测试的优点包括：可在现场真实应力条件下获得土壤参数，获得的数据沿深度连续，可克服取样问题或样品干扰。研究地点位于万隆的 Gedebage 地区，该地区目前正经历着巨大的发展。该地区的土壤属于软土，一般剪切强度较低。粘土剪切强度（Su）的测定是净锥阻和锥系数（Nkt）的比值。根据 CPTu 测试数据对评估软土抗剪强度中的 Nkt 系数进行更深入的研究，将通过实验室测试进行验证。结果表明，适合 Gedebage 地区的 Nkt 系数为 13-15。实验室测试结果和现场 CPTu 测试结果的抗剪强度参数范围如下：0-10 米深度 Su >25 kPa，10-25 米深度 Su 10 kPa 左右，25-31 米深度 Su >100 kPa。

Several offshore platforms operating in the Java Sea have reported experiencing scour at varying depths, raising concerns about the safety and integrity of these structures. Scouring, an erosion phenomenon that occurs around these offshore platform structures due to their presence, is one of the most common issues encountered. The presence of scour can have a significant impact on the safety of these structures. To comprehend the implications of scour on structural safety, sensitivity analysis proves to be an invaluable tool. Sensitivity analysis establishes a relationship between changes in the safety parameters of the structure, obtained through linear analysis, and the depth of scour. By investigating this connection, sensitivity curves can be generated, enabling a conservative prediction of alterations in the strength parameters of the structure due to scour. In this study, a four-legged jacket platform structure underwent linear analysis under storm and seismic conditions using the SACS software. The scour phenomenon was simulated by adjusting the mudline's elevation beneath the structure, modifying the pile coordinates, reducing the length of piles beneath the mudline, and accounting for soil characteristics at each scour depth in the model. The sensitivity analysis revealed that the safety factors of the upper structural components, connections, and piles decrease at varying rates corresponding to each component type as the scour depth of the platform increases. By implementing these sensitivity curves, engineers and operators can make informed decisions regarding the maintenance and retrofitting of offshore platform structures to ensure their ongoing safety and structural integrity in the face of scour-related challenges. This research provides valuable insights into the critical relationship between scour depth and structural safety, enhancing our ability to protect offshore operations in the Java Sea and similar environments.

Kawasan Ibu Kota Negara (IKN) yang berada di Kalimantan Timur merupakan kawasan strategis yang diproyeksikan sebagai ibu kota Negara Indonesia yang baru, oleh karena itu dibutuhkan infrastruktur sumber daya air untuk mendukung pembangunan yang ada di IKN. Analisis Intensity-Duration-Frequency curve (kurva IDF) pada daerah aliran sungai (DAS) IKN diharapkan mampu memperkirakan besaran intensitas hujan dengan berbagai kala ulang untuk mendesain berbagai jenis bangunan air seperti drainase, gorong-gorong, dan kanal banjir. Data hujan yang berupa data harian menjadi pertimbangan untuk melakukan analisis kurva IDF menggunakan persamaan Mononobe dan persamaan Sherman. Distribusi curah hujan pada DAS IKN mengikuti distribusi Log-Normal dan menghasilkan nilai curah hujan rancangan dengan berbagai kala ulang seperti 2, 5, dan 10 tahun. Trend intensitas hujan pada DAS IKN menunjukkan bahwa intensitas hujan menurun seiring dengan bertambahnya durasi hujan. Persamaan Sherman diketahui memberikan nilai intensitas hujan yang lebih tinggi dari persamaan Mononobe pada durasi pendek yaitu kurang dari dua jam sedangkan untuk durasi lebih dari dua jam terjadi sebaliknya. Intensitas curah hujan maksimum sebesar 419,67 mm/jam pada kala ulang 100 tahum pada durasi 5 menit atau 0,083 jam. Intensitas minimum terdapat pada durasi 5 jam dengan kala ulang 1,1 tahun sebesar 7,74 mm/jam. Sedangkan hasil analisis dengan pendekatan Sherman, dengan kala ulang dan durasi yang sama, diperoleh nilai maksimum 231,42 mm/jam dan nilai minimum 10,88 mm/jam.

Penggunaan Self Compacted Concrete (SCC) pada industri konstruksi terus berkembang. Perbedaan tingkat kerumitan konstruksi mensyaratkan tingkat aliran dan kemampuan memadat SCC yang bervariasi. Prosedur perancangan SCC tidak ditetapkan secara pasti karena banyaknya parameter yang terlibat. Penelitian ini menggunakan metode perancangan bertahap dengan menentukan komposisi fly ash maksimum untuk substitusi semen tipe I yang menghasilkan kuat tekan mortar tertinggi. Superplasticizer ditambahkan pada mortar sehingga menghasilkan flow mortar dengan tingkat aliran lebih dari 250 mm. Komposisi terbaik digunakan untuk perancangan SCC. Pasir yang digunakan adalah Pasir Progo kering udara (Gradasi IV) dan Kerikil Clereng kering udara berukuran 4,8 mm – 9,6 mm. SCC diperoleh dengan menambahkan kerikil pada mortar menggunakan koefisien volume absolut 1,4; 1,6 dan 1,8 terhadap volume rongga 1 m3 kerikil. Uji reologi beton segar meliputi slump flow, v-funnel, L-box dan segregation resistance untuk menentukan kelas SCC. Uji tekan 3 kubus mortar setiap variasi dilakukan pada umur 3 hari sedangkan uji tekan 3 silinder SCC setiap variasi dilakukan pada umur 3 dan 28 hari. Substitusi semen dengan fly ash 10% dan SP 1,8% memberikan hasil flow mortar 320,65 mm dan kuat tekan 22,07 Mpa dipilih sebagai mortar SCC. SCC dengan koefisien volume absolut 1,8 menghasilkan kuat tekan tertinggi sebesar 30,48 MPa.

This research paper conducts an evaluation of residential satisfaction within government-provided four-storied apartment complexes situated in civil-servant housing areas in Naypyitaw City, Myanmar. As the construction of these apartment buildings continues to address the housing demands of civil servants, comprehending the determinants of residents' contentment becomes paramount. The study encompasses data collected from 500 households through structured questionnaires employing a multi-cluster sampling approach. These questionnaires utilize a five-point Likert Scale format to gauge residents' levels of importance and satisfaction. Gap Analysis is employed to scrutinize the gathered data, ultimately identifying seven pivotal attributes that hold the potential to substantially enhance residential satisfaction. These attributes encompass ceiling height, apartment layout plan, room and corridor dimensions, quantity of rooms, staircase design, neighborhood relations, and proximity to police stations. Based on these revelations, recommendations are tendered, advocating the modification and reevaluation of these attributes in forthcoming housing developments.

Purnawan","doi":"10.28932/jts.v20i1.7428","DOIUrl":"https://doi.org/10.28932/jts.v20i1.7428","url":null,"abstract":"This research paper conducts an evaluation of residential satisfaction within government-provided four-storied apartment complexes situated in civil-servant housing areas in Naypyitaw City, Myanmar. As the construction of these apartment buildings continues to address the housing demands of civil servants, comprehending the determinants of residents' contentment becomes paramount. The study encompasses data collected from 500 households through structured questionnaires employing a multi-cluster sampling approach. These questionnaires utilize a five-point Likert Scale format to gauge residents' levels of importance and satisfaction. Gap Analysis is employed to scrutinize the gathered data, ultimately identifying seven pivotal attributes that hold the potential to substantially enhance residential satisfaction. These attributes encompass ceiling height, apartment layout plan, room and corridor dimensions, quantity of rooms, staircase design, neighborhood relations, and proximity to police stations. Based on these revelations, recommendations are tendered, advocating the modification and reevaluation of these attributes in forthcoming housing developments. This underscores the imperative need for creating a livable city by ensuring the provision of essential services in closed proximity to residential areas.","PeriodicalId":52838,"journal":{"name":"Jurnal Teknik Sipil","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140789831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Air merupakan kebutuhan pokok yang sangat penting bagi kehidupan manusia. Pemenuhan kebutuhan air di Desa Beru sangat bergantung pada air tanah yang diambil dengan membuat sumur. Besarnya ketergantungan masyarakat terhadap keberadaan air sumur, maka sangat penting untuk memantau dan menilai kualitas air tanah di Desa Beru. Kurangnya penelitian terkait menjadikan penelitian ini sangat penting untuk dilakukan. Tujuan dari penelitian ini adalah untuk menganalisia kualitas air tanah di Desa Beru Kecamatan Jereweh Kabupaten Sumbawa Barat. Parameter uji kualitas air menggunakan parameter pH, temperatur, konduktivitas, TDS, dan DO. Nilai rata-rata setiap parameter secara berurutan sebesar 7,07; 30,18OC; 752,71 µS/cm; 377,91 mg/L; dan 4,83 mg/L. Secara rata-rata, kualitas air tanah tergolong baik dan memenuhi standar baku mutu yang dipersyaratkan. Berdasarkan perhitungan indeks pencemaran, mutu air berdasarkan parameter pH (PIj=0,92) dan TDS (PIj=0,497) tergolong baik, sedangkan mutu air berdasarkan parameter temperature (PIj=1,079) dan DO (PIj=1,162) masuk kategori tercemar kecil tapi relatif masih aman digunakan untuk kebutuhan higiene sanitasi.
