Abstract

Surabaya plays a crucial role as the economic center in eastern Indonesia. However, it is identified as a waterlogging-prone area. Several regions have experienced flooding with water heights ranging from 10 to 70 cm, lasting up to 6 hours. This issue also happened in the Donowati area, Surabaya where mismatches in the construction of urban drainage channels with design criteria were found, resulting in inundation. These inundations cause infrastructure damage, health risks, disruption of activities, and economic losses. This research aims to evaluate and optimize the drainage system in Jalan Donowati, Surabaya. The research was conducted by collecting existing canal dimension data and hydrological data. Furthermore, data analysis was carried out, including hydrological and hydraulics analysis. Repairs will be carried out if an overflow occurs so the channel can run normally. The results showed drainage channels on Jalan Donowati could not accommodate rainwater due to their small capacity, namely one secondary and three tertiary channels. The channel redesign obtained dimensions of 1 m x 1 m for the secondary channel and 0.7 m x 0.6 m for the tertiary channel. The validation results show that the new dimension is safe against high rainfall. In addition to channel re-dimensions, inlet additions were also made to allow rainwater to enter the drainage canals more efficiently. So that with this new dimension, it can prevent inundation that occurs during the rainy season.

Abstract

Drainage refers to a vital component for water disposal so that a region or area can hinder potential puddle due to excessive water on the land surface. Therefore, a good plan adjusting the land condition of residential area belongs to a fundamental matter. Jade Hamlet Residence is located on Hulaan highway, Hulaan Urban Village, Menganti District, Gresik Regency, covering an area ±20 hectares and consisting of housing area, park, public facility, and catchment area. The drainage channel at this residence serves as the drainage for rain water and household dirty water disposal. During the rainy season in 2018 and 2019, the channel and bozem or drainage basin of this residence encountered overflowing and eventually caused puddle. To overcome this problem, the capacities of bozem and channel are in need of analysis and evaluation so as to figure out the runoff volume that can be accommodated in the bozem and investigate the discharge planned in the drainage channel by employing Log Person III method, chi-square distribution fit test, Kolmogorov-Smirnov test, rational formula, and exponential method. The results of analysis and evaluation demonstrated that the bozem capacity could not afford the runoff discharge (298.35 m3 309.55 m3), thereby demanding additional length and depth against the existing bozem. Meanwhile, the calculation of flood discharge planned for the drainage channels of S4.Ry3, S6.Ry1, S6.D1, S6.I2, S6.Cs1, S6.Rc1, S6.Rc2 indicate that they need redesigning by altering the channel dimension as the discharge capacity exceeds the channel.

Abstract

The construction of a 9-meter deep basement on clay soil with a soft consistency necessitates the use of a sheet pile for soil retention. Selected due to the soft soil conditions and a high groundwater level at the site, the sheet pile effectively addresses these challenges. The design calculations for the sheet pile, based on the Terzaghi concept, incorporated both active and passive earth pressures determined using the Rankine method. Analysis revealed a lateral force of 19,624 t/m² at a depth of 9 meters. The resulting design specifies a 10-meter embedded concrete pile without anchors, requiring a total sheet pile length of 19 meters. The chosen sheet pile type is W-600 A-1000. Alternatively, with anchors, the design calls for a 4-meter depth using type W-325A-1000 concrete sheet pile, with one anchor installed at a depth of 3 meters. The anchor's tensile strength is 5.46 tonnes, resisting a force of 113.817 Tm with a diameter of 5 cm. Modelling analysis showed that unanchored sheet piles have a safety factor of 0.770 and exhibit lateral deformation of 0.00803 meters. Conversely, the addition of anchors enhances the safety factor to 1.146 and increases lateral deformation to 0.0195 meters, indicating that anchors significantly improve safety and reduce deformation.

Abstract

There are up to 50-centimeter-high puddles on the road due to the Jetis Road Drainage Channel in Mojokerto Regency's incapacity to handle the flood discharge from the drainage catchment area. The Jetis Road drainage channel's size and channel bed slope will be affected by the meeting point of the 1000 m long secondary channel and the Jetis Road drainage outlet. The objective of this research is to evaluate the efficiency of drainage channel design considering the implications of the drainage existing condition due to inconsistent dimension and sedimentation. The drainage channel is designed to handle a total discharge of 4.6 m3/sec during 10 years return of period. Under these circumstances, a trapezoidal channel with a width of one meter and a depth of two meters is needed. The Jetis Road drainage channel's enlarged dimensions result in a flood water level of 1.8. The Jetis Road drainage channel has a freeboard of 0.2 meters since the flood water level that occurs in the channel with its new dimensions is 1.8 meters. The flow rate in the intended channel serves as the control in this study to determine channel size. The channel's maximum flow velocity of 1.44 m/sec satisfies the 1.5 m/sec maximum flow velocity allowed in concrete channels.

Abstract

Tanah ekspansif merupakan tanah lempung yang mempunyai level plastisitas yang tinggi, potensi kembang susut tinggi dengan adanya pergantian musim, sehingga sebelum digunakan sebagai tanah dasar di diperlukan stablilisasi untuk menurunkan nilai Indeks Plastisitas dan menaikkan daya dukung. Stabilisasi adalah cara untuk merubah dan memperbaiki sifat-sifat tanah agar memenuhi persyaratan sebagai tanah dasar. Tanah di daerah Lakarsantri, Surabaya Barat memiliki jenis tanah ekspansif, sehingga bangunan sipil terutama jalan mengalami kerusakan walaupun volume lalu lintas rendah. Pada penelitian ini akan dilakukan analisis tingkat kepadatan dan nilai CBR tanah ekspansif yang distabilisasi menggunakan campuran lumpur lapindo dan kapur padam dengan prosentase campuran lumpur lapindo 15%, 20%, 25, 30% dan kapur padam 7% pada setiap pencampuran serta waktu pemeraman 0,7, dan 14 hari. Hasil yang diperoleh dari penelitian ini dapat disimpulkan sebagai berikut, karakteristik tanah asli termasuk tanah berbutir halus, plastisitas tinggi, tingkat kepadatan sedang dan nilai CBR rendah. Karakteristik tanah lempung setelah distabilisasi menurut hasil uji atterberg limit memiliki nilai liquid limit 45,35%, indeks plastisitas sebesar 11,32%, termasuk katagori cukup baik. Prosentase dan pemeraman terbaik pada campuran lumpur lapindo 30% dan kapur padam 7%, pada pemeraman 14 hari, tanah dalam kondisi paling padat 1,75 gr/cm³ dan nilai CBR terbesar 8,52% termasuk katagori cukup baik.

Abstract

Tanah lempung ekspansif di Kecamatan Lakarsantri, Surabaya Barat, memiliki potensi kembang–susut yang tinggi sehingga menyebabkan rendahnya daya dukung tanah dasar. Penelitian ini bertujuan untuk menganalisis pengaruh penambahan kapur padam terhadap peningkatan nilai California Bearing Ratio (CBR) tanah lempung ekspansif. Penelitian dilakukan pada dua titik lokasi penyelidikan, yaitu titik A dan titik B. Metode perbaikan tanah yang digunakan merupakan kombinasi stabilisasi kimiawi dan mekanis dengan variasi kadar kapur padam sebesar 4%, 8%, dan 12% dari berat kering tanah serta waktu pemeraman (curing time) selama 7, 14, dan 28 hari. Pengujian daya dukung tanah dilakukan melalui uji CBR laboratorium berdasarkan SNI 03-1744:2012. Hasil pengujian menunjukkan bahwa kondisi awal tanah pada kedua titik memiliki nilai batas cair (LL) lebih dari 50%, indeks plastisitas (IP) sebesar 20%, serta nilai CBR masing-masing sebesar 2,23% pada titik A dan 2,49% pada titik B. Penambahan kapur meningkatkan nilai CBR, namun menunjukkan respons yang berbeda pada setiap lokasi. Nilai CBR optimum pada titik A sebesar 8,79% diperoleh pada kadar kapur 12% dengan curing time 28 hari, sedangkan nilai CBR optimum pada titik B sebesar 6,43% diperoleh pada kadar kapur 4% dengan curing time 14 hari. Hasil penelitian menunjukkan bahwa efektivitas stabilisasi tanah menggunakan kapur sangat dipengaruhi oleh karakteristik tanah dan waktu pemeraman.
