Abstract

The Colo Timur Irrigation Area covers 20,601.80 hectares with a main canal length of 64.15 km, passing through the regencies of Sukoharjo, Karanganyar, Sragen, and Ngawi. The water flow comes from the Wonogiri Serbaguna Dam, which is dammed by the Colo Weir in Sukoharjo. This irrigation area faces issues with uneven water distribution, and there is a need to check the water irrigation from the intake gates to conclude whether the operation and maintenance of the irrigation network are in accordance with standards. The study was conducted on the secondary canals of Geneng, Pulosari, and Krikilan, which are located upstream, midstream, and downstream, respectively. On the Geneng secondary canal, measurements were taken at B CT 5, Ge 1, and Ge 8 Ka. On the Pulosari secondary canal, measurements were taken at B CT 29, BPo 1, BPo 12 Ka, and BPo 12 Ki. On the Krikilan secondary canal, measurements were taken at B CT 40, Kk 1 Ka, and Kk 1 Ki. This study uses the Ratio of Water Distribution Implementation (RWDI) to determine the category of water distribution. The water discharge from the intake gates does not match the allocated water discharge. Factors causing the discrepancy in water discharge include (a) intake gates not being opened according to plan, (b) the presence of water pumps in the canals reducing irrigation water, and (c) the field operation system implementing water distribution rotations.

Abstract

The road environment not only influences the physical aspects of a city but also significantly impacts the psychological state of road users. This study aims to explore the relationship between road infrastructure such as sidewalk design, lighting, and signage, with perceptions of urban aesthetics and road psychology within the context of detailed urban development. Qualitative research methods were employed, including field observations, in-depth interviews, and document analysis, to assess how these factors affect the behaviors and feelings of road users and surrounding residents. Findings indicate that well-designed road infrastructure can enhance feelings of safety, comfort, and visual satisfaction among road users, whereas poor integration may lead to stress and discomfort. The implications of this research underscore the importance of considering psychological aspects in the planning and development of detailed urban environments to create road environments that are not only functional but also support the psychological well-being of the community.

Abstract

Concrete typically consists of coarse aggregate, fine aggregate, cement, and water. However, cement production generates significant carbon dioxide emissions nearly equivalent to the tons of cement produced. One alternative to conventional concrete, which replaces cement as a binder, is geopolymer concrete. Geopolymer concrete utilizes fly ash or other materials containing silica and alumina as the binder. Unlike cement, which forms a binder through hydration, geopolymer concrete uses a chemical reaction with alkali activators such as Na2SiO3 (sodium silicate) and NaOH (sodium hydroxide). This study investigates the toughness of geopolymer concrete using cylindrical specimens measuring 15 cm x 30 cm with varying Na2SiO3 to NaOH ratios of 1:0.5, 1:1, and 1:1.5, cured at room temperature for 28 days. The study results show that the highest toughness was achieved with a sodium silicate to sodium hydroxide ratio of 1.5, yielding 2.7394 x 105 J/m3. Meanwhile, the toughness values for sodium silicate to sodium hydroxide ratios of 0.5 and 1.0 were 2.3748 x 105 J/m3 and 2.5821 x 105 J/m3, respectively. Thus, increasing the sodium silicate to sodium hydroxide ratio from 0.5 to 1.5 at an activator content of 0.43 affects the toughness of geopolymer concrete.

Abstract

This study aims to redesign the superstructure of the Sambungrejo Bridge in Sidoarjo, which has a span length of 16 meters. The Sambungrejo Bridge originally used WF 700.300.15.28 steel girders and C 300.100.10.16.8 diaphragms,that are susceptible to corrosion, especially during floods. The redesign involves replacing the steel girder with a Prestressed Concrete I Girder (PCI Girder) H-900mm, 170mm thick, produced by WIKA Beton, known for its superior corrosion resistance and construction efficiency. The research methodology includes structural analysis using Robot Structural Analysis Professional (RSAP) software, calculation of prestressing forces, and the design of the prestressing cable layout. The results of this study demonstrate that the use of PCI Girder does not reduce the structural dimensions of the bridge but also proves to be more compatible with the flood water conditions at the site. The total cost required for implementing the new bridge superstructure design is Rp. 4.372.201.

Abstract

Indonesia has many dams that have been established since the Dutch Colonial era, including the Plumbon Dam located in Wonogiri Regency. During this time, many changes have occurred, including changes in flood discharge. The impact of climate change and land use change around the watershed has led to an increase in the frequency of extreme rainfall, which contributes to an increase in flood discharge. This study aims to evaluate the height of Plumbon Dam, assessing its safety against the new planned flood discharge. A 1000-year return period discharge and PMF analysis of Plumbon Dam was conducted for the year 2024. The calculation of rainfall R1000 and PMP using the Isohyet method, with the calculation of synthetic unit hygrograph using the HSS Nakayasu method. The calculation results obtained flood discharge Q1000 value of 73,33 m3/s and QPMF obtained at 107,75 m3/s. The required dam crest elevation was obtained, for Q1000 discharge + 227,43 m and QPMF + 226,96 m. The results of calculations using the 2024 design flood discharge are stated to experience overtopping of the 1000-year return period discharge because the flood water level exceeds the existing dam crest height of + 227 m and is safe against QPMF discharge.

Abstract

The analysis of water irrigation loss is very importance, as the loss of water in irrigation canals may have a detrimental impact on the overall performance of the irrigation system. The occurrence of water loss can be attributed to a multitude of factors, including damage to the channel, evaporation, seepage, and other phenomena that diminish the usability of the water in question. Consequently, an analysis of water loss can assist in determining the quantity of water lost, as well as the factors that contribute to the occurrence of water loss. This enables the implementation of preventive and corrective measures to enhance the efficiency of water usage. The objective of this study is to ascertain the value of water loss in the secondary channel of the East Colo Irrigation Area. The research methodology entails direct field measurement of water irrigation loss. The results demonstrate that the average value of the percentage of water loss from the Geneng Secondary channel is 11.07%, with a maximum water loss percentage of 23.66% and a minimum water loss percentage of 2.84%. In the Pulosari Secondary channel, the average value of the percentage of water loss is 13.82%. In the Krikilan Secondary channel, the maximum water loss percentage was observed to be 18.38%, while the minimum is 9.36%. The average value of the percentage of water loss was found to be 22.81%, with a maximum of 26.01% and a minimum of 19.22%. The factors that cause water loss obtained an average percentage value of water loss due to evaporation of 0.22% in the Geneng Secondary channel, 0.04% in the Pulosari Secondary channel, and 0.01% in the Krikilan Secondary channel. For the average percentage value of water loss due to seepage of 0.001% in the Geneng Secondary channel, 0.0001% in the Pulosari Secondary channel and Krikilan Secondary channel.
