Abstract

The construction of drinking water pipeline networks is a critical component of a sustainable Drinking Water Supply System (SPAM). The success of pipeline construction is heavily influenced by the appropriate selection of construction methods tailored to on-site conditions. The Umbulan Sub-Distribution Center (Sub DC) Bunder–Manyar SPAM project in Gresik Regency is a strategic project utilizing High-Density Polyethylene (HDPE) pipes with large nominal diameters and a significant route length. Diverse on-site conditions, such as open areas, road crossings, and river crossings, require the application of appropriate construction methods to ensure the work proceeds effectively and efficiently. This study aims to analyze the construction methods for HDPE DN pipelines applied in this project, analyze the costs and duration of the work, and evaluate project progress based on actual on-site conditions. The research method used is a descriptive approach combining qualitative and quantitative methods. Data was obtained through direct field observations as well as a review of the Cost Estimate (RAB), work schedule, and project progress reports. The research results show that the open-cut method is predominantly used in areas with open terrain and easy access, while the Horizontal Directional Drilling (HDD) method is applied in areas crossing roads and rivers. Based on the analysis of costs and implementation time, the application of methods appropriate to site conditions can improve work efficiency and support the achievement of project progress in accordance with the plan. Thus, the selection of the appropriate implementation method plays a crucial role in the success of drinking water pipeline network projects.

Abstract

A stable supply of irrigation water is a crucial factor for agricultural success, but its effectiveness depends heavily on the physical integrity of the irrigation network. This study aims to analyze the structural condition of physical assets and evaluate the performance of irrigation structures in the primary canal of the Cokro Irrigation District (DI), Jeru Village, Tumpang Subdistrict, Malang Regency. The evaluation focused on a 927-meter-long primary channel serving a 30-hectare rice field area. The research method used was quantitative descriptive, involving field surveys (inventory) and technical measurements in accordance with the standards set forth in Ministry of Public Works and Public Housing Regulation No. 12/PRT/M/2015. Primary data were obtained through visual inspections at 15 points along the primary channel and its ancillary structures to assess the extent of damage. Data analysis included calculating the percentage of network damage and determining the physical performance index. The results of the study indicate that the physical condition of the infrastructure is at the “cautionary maintenance” level. A total of 73.34% of the assets are in serviceable condition (Good and Slightly Damaged), but there are 26.67% of critical points categorized as Moderately Damaged, Severely Damaged, and Abandoned. The predominant forms of damage are sedimentation and the growth of wild vegetation that obstructs water flow. Based on calculations, the performance index of the Cokro irrigation system is 72.82%, which is classified as “Function impaired, requires repair.” The proposed technical recommendations are immediate rehabilitation at critical points and optimization of preventive maintenance to restore optimal water service functionality.

Abstract

This study aims to evaluate the physical and functional performance of infrastructure and determine management priorities in the Beringin Irrigation Area (DI), Wajak District, which serves 131 hectares of agricultural land. Decreased performance of irrigation networks caused by sedimentation conditions and existing damage. The method used is a quantitative approach through a survey of infrastructure inventory in each irrigation network segment. Performance evaluation is carried out based on the Irrigation System Performance Index standard, which includes assessment of the physical condition and function of the building. The infrastructure of DI Beringin as a whole includes the main building (intake), carrier channels, complementary buildings, sewers, and inspection roads. The results of the study showed variations in conditions in each infrastructure component. The main building shows optimal performance with a value of 81% (Good/Routine Maintenance category). On the other hand, complementary buildings recorded the lowest value of 60.59% which indicates the category of Moderately Damaged and requires handling in the form of rehabilitation. These findings confirm that although the infrastructure is still complete in its existence, a priority management strategy is needed to prevent further degradation of function. The priority of the treatment produced is the rehabilitation of complementary buildings and sewers. Periodic maintenance for Carrier Lines and routine maintenance for main buildings and inspection roads. Medium handling priority for complementary buildings and sewer lines and low for carrier lines. The results of this study are expected to be recommendations for irrigation managers in determining the scale of maintenance priorities so that the distribution of water to agricultural land is maintained in a sustainable manner.

Abstract

A drainage channel for a water structure that can properly drain water to the downstream section of a channel. A channel capable of accommodating Qrencana will be able to free the city from flooding. The issue of flooding is a concern for various parties, especially the local community, and the government also has an important role to play. The research location is on Jalan Raya Candi II, Klojen District, Malang City, East Java. The design flow calculation method uses the rational method with a 5-year and 10-year return period. The flood discharge for a 5-year return period is 3585 m3/second and for a 10-year return period is 3934 m3/second. At the research location, there are a total of 6 channel sections and after evaluation, 1 channel is still sufficient to accommodate the design flood discharge for a 5-year and 10-year return period. However, there are 5 channels that are insufficient to accommodate the design flood discharge for a 5-year and 10-year return period. For channels that are insufficient, they need to be redesigned with Q5years added to the protection height (W) and controlled with Q10years to obtain the appropriate capacity in an effort to prevent flooding at the research location. The redesign of channel 1 is b = 2.4 m and channel height = 2.1 m in the channel design. The channel dimensions are the same from channel 1 to channel 6, and a storage well is recommended to overcome surface water runoff.

Abstract

The Seputuk and Rian Watersheds in Muruk Rian Subdistrict, Tana Tidung Regency, North Kalimantan Province, are areas that are prone to flooding due to high rainfall and the morphological conditions of the watersheds. This study aims to analyze and compare the planned flood discharge on the Simpang Seputuk Road section using the Snyder Synthetic Unit Hydrograph (HSS) and Nakayasu HSS methods. The data used is the maximum daily rainfall from the Salap Rainfall Station during the 2008–2021 period. The planned rainfall analysis was carried out using the Gumbel and Log Pearson Type III probability distributions, followed by a suitability test using the Chi-Square and Smirnov Kolmogorov methods. The selected planned rainfall was transformed into effective rainfall as input in the flood discharge calculation. The analysis results show that the Nakayasu HSS method produces a higher peak discharge than the Snyder HSS method in both watersheds. In the Seputuk watershed, the Nakayasu method's peak discharge for a 25-year return period reached 501.80 m³/sec, while the Snyder method produced 233.47 m³/sec. Meanwhile, in the Rian watershed, the Nakayasu method produced a peak discharge of 319.83 m³/sec and the Snyder method produced 73.06 m³/sec. This difference shows that the Nakayasu HSS method is more conservative and sensitive to watershed morphometric characteristics, making it more suitable for flood control planning in areas with flood risk. Meanwhile, in the Rian watershed, the Nakayasu method produced a peak discharge of 319.83 m³/sec and the Snyder method produced 73.06 m³/sec. This difference indicates that the Nakayasu HSS method is more conservative and sensitive to the morphometric characteristics of the watershed, making it more suitable for flood control planning in areas with high flood risk, while the Snyder method can be used as a preliminary estimate in watersheds with limited data.
