Abstract

This study analyzes energy loss (head loss) in a 40×60 cm U-Ditch drainage channel on Jalan Cemara XII, Kediri City. The methods used are quantitative approaches with hydrological (Mononobe, Rational) and hydraulic (Manning, Darcy–Weisbach) calculations. The results show a planned discharge of 0.07985 m³/s, a flow velocity of 1.3369 m/s, and a total energy loss of 2.20 m. Comparison with field data shows a difference of 3.77%, which means that this analysis model is valid. The channel capacity safety factor reaches 4.0 and the flow is subcritical (Fr = 0.96). This study provides a scientific basis for evaluating the hydraulic efficiency of precast channels and can be developed into a real-time monitoring-based Smart Drainage system.

Abstract

Flooding is a serious problem that often occurs due to uncontrolled land use change. This study aims to evaluate the capacity of the retention pond at PT Tactical Garment Garut in controlling runoff using the Storm Water Management Model (SWMM) version 5.2. PT Tactical Garment Garut, located in Haruman Village, Leles Subdistrict, Garut Regency, faces challenges in managing runoff due to the conversion of vegetated land into covered land for the construction of an apparel industry. The research method involved hydrological and hydraulic modeling using SWMM to calculate the 5-year and 10-year return period channel discharge, and determine the effectiveness of the existing retention ponds. The modeling results showed that the retention pond was able to accommodate a maximum runoff of 89.55 m³/sec for 6 hours. The maximum inflow (total water discharge) into the retention pond is 961.29 m³. However, the calculation of the effectiveness of the retention pond shows that the retention pond is only able to cope with 1.04% of the incoming flood volume, which indicates that the capacity of the retention pond is inadequate. This study suggests further evaluation of the capacity of the retention pond as well as possible expansion or infrastructure improvements to enhance the flood handling capability of the area.

Abstract

Dewatering is used to lower the groundwater level in order to prevent uplift forces from interfering with construction work. Dewatering is generally used in the construction of high-rise buildings that will usually add a basement floor. The purpose of this study is to determine the need for pumps based on the excavation area, soil type and the amount of water that must be released based on the rain intensity of the Bandung area using the predrainage method. The case study in this research is a 13-story building in the construction project of a pilot-scale product development building (building No. 34) of PT Bio Farma (Persero). The calculation results show that the soil type is inorganic clay with high plasticity and based on the excavation zone of ± 1,516.52 m2 which is divided into three zones, the pump requirements for dewatering work require 3 pumps in each excavation zone with a pump capacity of 150 liters/minute. The amount of water that must be released based on rain intensity data of the Bandung area ± 50 mm obtained the result of 60 m3 / hour.

Abstract

Flooding is one of the most frequent and destructive natural disasters, impacting human lives and causing economic damage. According to data from the Indonesian National Disaster Management Agency (BNPB), there were 920 flood incidents recorded in West Java between 2014 and 2023. One major flood event occurred in the Cimanuk River, Garut Regency, in 2016, resulting in significant damage to the surrounding areas. The Cimanuk River is part of a watershed that includes several tributaries or sub-watersheds (Sub-DAS) with potential to cause flooding. The Ciojar Sub-watershed, located in Garut Regency, is one such tributary that frequently contributes to flooding. It flows through residential areas, plantations, and rice fields. Most of the land around the Ciojar Sub-watershed is used for agriculture, while some residential areas lie at lower elevations, making them especially vulnerable to flooding.This study adopts a quantitative approach to analyze the frequency and impact of floods in the region. It has two main objectives: to identify the months and years in which rainfall exceeded the five-year flood threshold (Q5), and to predict flood events exceeding Q5 from 2024 to 2027. Flood discharge was calculated using the Synthetic Unit Hydrograph method from the Soil Conservation Service (SCS), while flood predictions were simulated using an Artificial Neural Network (ANN) Backpropagation method with MATLAB software.The analysis of flood discharge based on a five-year return period for 2014 to 2023 yielded the following values: 99.250 m³/s (2014), 10.459 m³/s (2015), 162.367 m³/s (2016), 194.384 m³/s (2017), 149.485 m³/s (2018), 168.318 m³/s (2019), 162.218 m³/s (2020), 8.870 m³/s (2021), 233.587 m³/s (2022), and 124.346 m³/s (2023).The predicted flood discharges for the five-year return period from 2024 to 2027 are: 128.513 m³/s (2024), 93.488 m³/s (2025), 78.318 m³/s (2026), and 172.255 m³/s (2027).

Abstract

This research examines the dimensional non-conformity of structural elements in the Subang Regency Transportation Agency Building. The purpose of this research is to identify and analyze the factors causing dimensional non-conformity of structural elements that can affect the integrity and safety of the building. The methodology used is the analysis of planning documents and construction implementation. The results showed that there were several structural elements that experienced dimensional discrepancies, which were caused by various factors such as planning errors, inaccuracies in implementation, and the use of materials that did not meet specifications. The implications of these findings indicate the need for increased supervision and quality control during the planning and execution stages of construction to ensure the dimensional conformity of structural elements in accordance with established standards. This research is expected to contribute to efforts to improve the quality of building construction in Subang Regency as well as in other regencies or cities.

Abstract

AC-WC (Asphalt Concrete—Wearing Course) adalah komponen penting dalam struktur perkerasan jalan yang dirancang untuk menahan beban maksimum dari lalu lintas. Lapisan ini terdiri dari campuran agregat kasar, agregat halus, bahan pengisi (filler), dan aspal. Fungsinya adalah sebagai lapisan antara yang menanggung beban tersebut secara efektif, memastikan ketahanan dan kestabilan perkerasan. Penelitian ini merupakan eksperimen untuk mencari alternatif filler dengan memanfaatkan limbah kulit domba yang menjadi sumber pencemaran lingkungan. Tujuan penelitian ini adalah untuk mengidentifikasi karakteristik campuran AC-WC dengan limbah kulit domba sebagai filler melalui pengujian Marshall. Variasi campuran limbah kulit untuk filler yang digunakan adalah  0 persen, 5 persen, 10 persen, dan 15 persen. Hasil penelitian menghasilkan bahwa filler limbah kulit domba mempengaruhi nilai stabilitas. Semakin besar presentase filler limbah kulit domba nilai stabilitas benda uji semakin meningkat. Untuk nilai flow, semakin besar presentase filler limbah kulit domba makan nilai flow semakin meningkat. Pada penelitian ini nilai VFB (Void Filled Butmen) dari campuran aspal dengan variasi abu limbah kulit domba cenderung mengalami penaikan seiring bertambahnya perrsentase dan memenuhi persyaratan. Untuk nilai VIM (Void in the Mix) pada campuran beraspal pada variasi kadar abu limbah kulit domba cenderung mengalami kenaikan dan penurunan. Kenaikan besarnya nilai VIM terjadi karena abu limbah kulit domba sebagai filler menunjukkan semakin besar rongga dalam campuran

Abstract

The Cilaki River stretches from upstream Pangalengan - Talegong to its downstream at the Cilaki bridge, the longest bridge in South Garut. According to BPBD volunteers on December 25, 2021, the Cilaki River Cianjur - Garut experienced very high rainfall which resulted in flooding that closed the main route connecting between regencies in Kertajadi Village, Cidaun District, Cianjur Regency, West Java Province submerged in floods as high as one meter. Therefore, this research aims to identify the planned flood discharge and analyze the inundation area in the Cilaki watershed using the HEC-RAS application, with the simulation results used to determine the level of flood vulnerability. The methods used include field surveys, hydrological analysis for the calculation of flood discharge according to the watershed area using the HSS Nakayasu method, and prediction of water levels through HEC-RAS for estimation of inundation area. The results showed a peak discharge at the 6th hour with a discharge of 403.17 m³/sec for a 25-year return period, 415.35 m³/sec for 50 years, and 424.58 m³/sec for 100 years. The inundation area reached 13,190 ha at the 25-year return period, 15,003 ha at 50 years, and 16,700 ha at 100 years.

Abstract

Indonesia is geologically located on the Ring of Fire, which means there are many active volcanoes along the Pacific plate. This is the cause of geological disasters, including earthquakes that often occur in Indonesia. According to SNI 1726:2019, there is an earthquake-resistant building concept, namely the Special Moment Bearing Frame System (SRPMK). Considering the frequent earthquakes, especially in Bandung Regency, it is very important to apply the Strong Column Weak Beam (SCWB) system to the Salman Hospital HCU (High Care Unit) building. This study aims to determine the application of the concept (SCWB) to the HCU building of Salman Hospital in an effort to anticipate damage in the event of an earthquake. The SCWB planning concept is a structural design innovation that makes the structural system flexible and allows deformation during an earthquake. This analysis starts from modeling, loading, and spectral response analysis. The calculation is carried out based on data obtained from field data with the data obtained is technical specification data and working drawings of the HCU Building of Salman Hospital. The results of the analysis show that the HCU building of RS Salman Hospital with beam dimensions of 300 x 500 and column dimensions of 450 x 450 does not meet the SCWB (Mnc ≥ 1.2 * (Mn- + Mn+) in accordance with SNI 2847: 2019, with a value of Mnc 110.313 kN.m and Mnb 179.200 kN.m and a redesign is required to meet the SCWB.

Abstract

One of the supporting factors for construction development work to be able to shorten the time, simplify, and control the quality of work is the need for heavy equipment. This study aims to compare the cost of procuring heavy equipment between buying or renting heavy equipment for the Ciplaz Garut construction project, in order to determine a more efficient alternative. The method used is financial analysis with Net Present Value (NPV) to measure the difference between investment and future net cash receipts, and the Internal Rate Of Return (IRR) method to analyze the rate of return on capital. The analysis results show that with a project duration of 2 years, the NPV for buying heavy equipment is -Rp. 5,845,078,344 (negative), while the NPV for renting heavy equipment is Rp. 959,780,692 (positive). In addition, the IRR for buying heavy equipment is 0 percent (less than MARR 4.25 percent), while the IRR for renting heavy equipment is 20.47 percent (greater than MARR 4.25 percent). Based on the results of the analysis that has been carried out, the procurement of heavy equipment with a rental system is more profitable to do than the procurement of a heavy equipment purchase system.

Abstract

Pedestrian facilities along Ahmad Yani Street in Garut Regency have undergone a change in function due to the increasing activities of street vendors (PKL). In addition to being occupied by street vendors, sidewalks are also used as parking spaces. This study aims to identify the physical condition of pedestrian facilities, compare the existing conditions with the standards set forth in the Circular Letter of the Minister of Public Works and Housing (PUPR) No. 02/SE/M/2018 Pd 03-2017-B on Technical Planning of Pedestrian Facilities, assess the comfort level of pedestrians based on user perception, and determine the walkability score evaluated by users using nine parameters of the Global Walkability Index (GWI). The research employs a qualitative method, as the nature of the Global Walkability Index (GWI) is perceptual—meaning the assessment is based on users’ perceptions to understand the condition of pedestrian facilities in the study area. The results show that the existing pedestrian facilities along Ahmad Yani Street are largely unavailable, and some that exist do not meet the required standards. User perception results indicate that the pedestrian paths are fairly comfortable to use. However, field observations reveal several obstacles that disrupt pedestrian comfort, such as the presence of street vendors and illegal parking. Furthermore, the walkability scores based on user assessments are as follows: Segment 1 – 42.25; Segment 2 – 43.2; Segment 3 – 43.1; and Segment 4 – 42.2. These values fall into the red category, indicating that the area is unsuitable for walking. This study proposes a pedestrian facility design that complies with applicable standards, as well as recommendations for the provision and improvement of pedestrian paths, including main and supporting facilities along Ahmad Yani Street. The suggested improvements are expected to serve as considerations for the Garut Regency Government in enhancing pedestrian infrastructure.
