Abstract

Saat ini pembangunan RSUD Kota Probolinggo terdapat issue terkait akses masuk ke rumah sakit. Pada kondisi eksisting terdapat jembatan yang menghubungkan Jalan Prof. Hamka dengan rumah sakit yang memiliki perbedaan elevasi cukup besar. Hal ini mengakibatkan kendaraan yang akan keluar-masuk dari rumah sakit mengalami kesulitan untuk melewati jembatan tersebut. Berdasarkan hal tersebut maka Pemerintah Kota Probolinggo melalui Dinas Pekerjaan Umum, Penataan Ruang, Perumahan dan Kawasan Permukiman Pemerintah Kota Probolinggo melakukan kerja sama pengabdian kepada masyarakat dengan DKPU ITS untuk membuat kajian detail desain peninggian jalan pada Jl. Prof. Hamka, agar mempunyai beda elevasi yang tidak besar dengan jembatan jalan akses menuju RSUD Kota Probolinggo. Desain jalan ini dilakukan dengan menggunakan data topografi area sekitar jalan, data tanah, data hujan dan data lalu lintas serta diskusi dengan pihak BBPJN VIII Wilayah Jawa Timur dan Bali. Hasil dari desain peninggian jalan didapatkan tebal perkerasan kaku adalah 55 cm dengan perkuatan geotekstil dan dinding penahan tanah, dimensi saluran tepi dengan menggunakan U-ditch 50x50x120 cm dan box culvert 80x100x120, pemasangan rambu, marka dan penerangan jalan umum. Hasil dari studi tersebut digunakan untuk membantu operasional RSUD Kota Probolinggo terkait perbaikan akses masuk rumah sakit dari jalan nasional.

Abstract

Peristiwa banjir pada DAS bertipe bulu burung di Banyuwangi dapat membawa dampak tingginya angkutan sedimen dan menurunnya kualitas air. Peluapan sungai Bomo dipacu karena intensitas hujan dan kecepatan aliran tinggi sehingga berdampak erosi, degradasi, dan kekeruhan yang tinggi. Tujuan penelitian untuk pengembangan alat ukur hidrometri berbasis sensor untuk deteksi konsentrasi sedimen dalam upaya mitigasi bencana banjir di Sungai Bomo. Tahapan penelitian melalui proses rancang bangun alat ukur hidrometri berbasis sensor berupa sensor ultrasonic (water level), water flow, turbidity, TDS, dan suhu, lalu simulasi pengukuran, dan pengambilan sampel sedimen untuk diuji karakteristik fisik di laboratorium berupa uji konsentrasi sedimen, berat jenis, berat volume, analisa saringan dan hidrometer. Parameter hidrometri diuji statistik melalui sediment-discharge rating curve. Hasil pengujian karakteristik fisik sedimen sungai Bomo selama 7 hari masing-masing di bulan basah dan kering diperoleh nilai rata-rata Cu 3,88 – 6,58 dan nilai rata-rata Cc 0,62 – 1,19, berat jenis rata-rata 2,5 – 2,55 dan berat volume 1,49 – 1,57 gr/cm3. Kalibrasi pembacaan sensor TDS terhadap konsentrasi sedimen dengan nilai MAE rata-rata sebesar 0,23 reliable terhadap kondisi lapangan. Hasil sediment-discharge rating curve pada musim kering diperoleh persamaan Qs_dry=35.653.(Qw)^0.9315 (R2 = 0.8269). Pada musim basah diperoleh persamaan Qs_wet=16.501.(Qw )^1.3719  (R2= 0.9336). Pada saat musim kering perlu waspada karena lahan lebih erosif karena nilai a > 26 yaitu 35.653 yang mengindikasikan laju erosi tinggi dan dapat menyebabkan banjir dan longsor. Alat ukur hidrometri berbasis sensor layak dikembangkan sebagai alat deteksi konsentrasi sedimen sebagai indikator muatan sedimen dalam upaya mitigasi bencana banjir dan tindakan konservasi lahan.

Abstract

Hydrological drought analysis in a river basin is crucial because it impacts water resource management, agriculture, drinking water supply, industry, ecology, and disaster risk mitigation. It plays a key role in water usage planning, safeguarding agricultural yields, and ensuring a stable drinking water supply. In the context of this research, the Corong River basin is used as a case study. This study aims to determine the level of hydrological drought (deficit) using the Threshold Level Method (TLM) and predict hydrological drought using the Seasonal Autoregressive Integrated Moving Average (SARIMA) model. This model understands the characteristics of drought and predicts drought in the Corong River basin for early mitigation and anticipation of drought in the region. The results of this research indicate a strong relationship between the Hydrological Drought Index (HDI) and streamflow and Precipitation (PRCP), which can be used to forecast future droughts. This model is highly robust and accurate in observing the level of hydrological drought (deficit, duration, and sharpness) and predicting drought events in the Corong River basin. These findings have significant practical implications for water management and disaster risk mitigation in this river basin while also advancing the scientific understanding of hydrological drought.

Abstract

The advancement of technology has provided various alternatives to address limitations in concrete construction. One effective method for enhancing the quality of concrete is by introducing additional materials, known as admixtures, during the concrete production phase. One such type of admixture that can significantly improve concrete quality is superplasticizer. The primary principle behind the use of superplasticizer is to create a repelling force between cement particles to prevent clumping, which can lead to the formation of air voids in the concrete. This, in turn, can reduce the strength or quality of the concrete. In this research, the focus will be on the use of concrete admixtures, specifically superplasticizer, to enhance concrete workability. One product of superplasticizer is Sika Viscocrete 3115 N, which will be used in this study. Superplasticizers like Sika Viscocrete 3115 N play a crucial role in improving the flow and workability of concrete mixes, making them easier to handle and place during construction. This leads to more efficient and high-quality concrete structures. The target compressive strengths are 30 MPa and 40 MPa with variations in the percentage of superplasticizer admixture usage at 0%, 0.25%, 0.5%, and 0.75%. The testing methods used to determine the workability value are the slump test and the slump flow test, while the compressive strength test is conducted using a compression testing machine at the Advanced Concrete Materials and Computational Mechanics Laboratory, Department of Civil Engineering, ITS. The study concludes that the addition of superplasticizer can enhance the workability of concrete but cannot optimally increase compressive strength. Additionally, different planned compressive strengths with the same percentage variation exhibit different trends. The addition of 0.25%-0.5% superplasticizer in both planned strengths still yields compressive strength above the planned levels, despite the decrease.

Abstract

The use of steel materials in building construction opens new opportunities for sustainable development, as steel exhibits corrosion resistance, durability, and reliability in terms of strength and ductility. Digital Image Correlation (DIC) is non-contact technique in which digital images of the surface of a test object are captured using high-resolution cameras.  This study conducted measurements of strain distribution on the specimen's surface using the DIC method throughout the entire tensile testing process. The study particularly focuses on examining changes in strain distribution during the melting phase and the local deformation phase leading to fracture. In this research, a comparison will be made between the load-displacement curves obtained from experimental laboratory testing and the results analyzed using the DIC method for SS400-grade steel material. Based on the results of the tensile test and DIC analysis that have been conducted, conclusions have been drawn in the research. The tensile test results of SS400 steel material with a thickness of 6 mm, 8 mm, 10 mm, and 12 mm meet the quality requirements in the tested specification standards, and the results of the force-displacement curve between the experimental test results and the DIC method obtained a minimum deviation with a value below 10%,. Therefore, it can be concluded that the DIC method exhibits a reasonably good level of accuracy, making it suitable for validating the results of experimental tests.

Abstract

Steel-reinforced concrete (SRC) provides numerous advantages, such as enhanced energy dissipation, ductility, stiffness, and strength, particularly in seismic performance. Several studies on the effect of axial loads on columns found that axial loads have an insignificant influence on column capacity, though they influence long-term performance. Beam-column joint elements are among the critical components that determine the seismic behavior of a structure. Inaccurate design of these joints can lead to fatal structural damage, potentially causing structural collapse. This study aimed to perform a numerical analysis of various joint configurations under cyclic and axial loads to identify models with the best seismic performance that consisted of four models using different SRC length parameters. The research used nonlinear finite element methods with the ABAQUS software, which enables detailed simulations of joint behavior, including predictions of failure mechanisms that are difficult to observe in experimental testing. The results of the analysis showed that the CS-02 model demonstrated the best seismic performance. Axial load increased the capacity in all models, improved energy dissipation in the RC model, slightly reduced dissipation in CS models, and caused different rotational behavior across models.

Abstract

Infiltration is an essential parameter in runoff, although its simulation remains challenging due to soil heterogeneity and complex structures. As soil moisture increases, infiltration capacity decreases nonlinearly, stabilizing when saturation is reached. Therefore, this study aimed to improve and validate the Horton Equation using field observations to determine infiltration capacity in watersheds. Overland flow observations were used to assess simulation accuracy from the previous studies, the sensitivity curve number was obtained at a range of 49–57. The results showed that high precipitation saturated initial losses and infiltration capacity, producing a greater runoff coefficient. The sensitivity curve numbers were obtained differently between Pandantoyo sub-basin (CN 49–53) and Ngadirejo sub-basin (CN 53–55). From modification runoff coefficient values (dimensionless,) for an ungauged catchment, it could be obtained function of f (R24, Sm), LU. Soil moisture value between Pandantoyo and Ngadirejo sub-basin was 3,562. It was also discovered that C was Q from AWLR observation and time of concentration, which influenced water discharge. A longer Tc led to lower discharge without increasing water levels. Furthermore, SCS Direct runoff method had minimal impact on runoff coefficients.
