Abstract

Optimal irrigation network performance is crucial to support agricultural productivity and meet the water needs of rice fields. However, the process of inventorying and assessing the condition of irrigation networks is still largely done manually, resulting in delays in reporting, potential recording errors, and low decision-making effectiveness. In accordance with the guidelines of Permen PUPR No.12/PRT/M/2015, a system is needed that is capable of evaluating the condition of irrigation assets more quickly, accurately, and in a standardized manner. This study aims to develop AsetAirKu, an AppSheet-based mobile application to support the process of inventorying and assessing the performance of irrigation channels and structures digitally, in an integrated manner, and in a way that is easy to use in the field. The research methods included a literature study on irrigation asset condition parameters, field data collection on channel profiles, sedimentation, embankment conditions, sluice gates, and other structure components, as well as the design of the application database structure. The application was developed through the stages of interface creation, data input flow, and report automation. The application was tested in the Kiaraenyeuh Irrigation Area as a case study, assessing its effectiveness during the data collection and assessment process in the field. AsetAirKu successfully integrated the data collection and assessment processes into a single platform. The field test results showed a network performance value of 70.65%, which is in the moderate category, with a moderate level of damage and recommendations for periodic maintenance. The application is capable of accelerating data recording, improving assessment accuracy, and generating reports automatically. The main constraint of the application is its dependence on an internet connection for data synchronization and report downloading. AsetAirKu has proven to be effective as a digital tool in assessing irrigation network performance, improving reporting efficiency, and supporting data-driven decision making.

Abstract

Electricity utilization in the provinces of South Sulawesi, Southeast and West Sulawesi is rapidly growing at a high rate. In Southeast Sulawesi Province, between the years of 2020 and 2024, it significantly grew by 12.66% per year. To meet with this high demand, for such a reason, PT Perusahaan Listrik Negara Indonesia Power/Electricity State Owned Company Info (PLN) ordered Nusantara II Barge Mounted Power Plant (BMPP) to PT PAL Surabaya and built a new jetty to mount the 60 MW plant in Wolo, Kolaka, Southeast Sulawesi. It is important to conduct risk management to ensure the success of the project by identifying and mitigating impact the risks that could be an obstacle smoothing delivery of the BMPP and the construction of its mounting dock. This study aims to analyze and manage risks for the construction of the BMPP Jetty. A risk analysis of the project was made to oversee what risks could interfere during the procurement stage, delivery the plant, implementation/construction stage up to the completion of the project. The research in this paper uses a descriptive qualitative approach and survey to examine the consequences of risks collected based on purposive sampling from Users, Contractors, Project Owners, and Project workers. The identified risks are then calculated and mitigated as necessary to control them. There were 47 risks identified, and after thorough analysis using the HIRADC method, 17 (36%) risks were low, 29 (62%) risks were moderate and 1 (2%) risk was high risk, which was related to the delivery of the BMPP itself. This research can help users, project owners, or other stakeholders in identifying, understanding, and responding to risks more effectively so that projects can be completed on time, without work accidents, but good quality, and within the planned budget. Good risk control and mitigation have made the project completed on time without accidents, delays, and with good quality delivered. The pattern of project implementation and management are be able to serve as reference to similar project in the future.

Abstract

The number of traffic accidents in Indonesia continues to increase every year, which contributes to the increasing death rate among the population. Similar conditions occurred in Pandeglang Regency, especially on the Labuan highway from KM 1 to KM 10, which experienced an increase in the number of accidents as seen from the LAKA (Traffic Accident) data from the Pandeglang Police from 2020 - 2024, both for Deaths (MD), Serious Injuries (LB) and Minor Injuries (LR). This study aims to identify the location of accident-prone points (black spots) along KM 1 - KM 10 of the Labuan highway, Pandeglang Regency and analyze the causal factors and solutions to the problems caused by black spots along KM 1 - KM 10 of the Labuan highway, Pandeglang Regency. The method used is to use primary data and secondary data. For data analysis using the Accident Rate and Equivalent Accident Number (EAN) methods with the use of limit values using the Final Control Limit (BKA) method and the Upper Control Limit (UCL) method. The results of the study show that: 1.) The number of traffic accidents on the Labuan Highway, Pandeglang Regency throughout 2020 - 2024 fluctuated; 2.) Location of accident-prone points (black spots) on the KM 1 - KM 3 segment, with EAN values exceeding the Upper Control Limit (BKA) and Upper Control Limit (UCL) values; 3.) The dominant factors causing accidents on Jalan Raya Labuan, Pandeglang Regency, especially on the KM 1 - KM 3 segment, include minimal street lighting, sharp bends, lack of traffic signs, and extreme road contours; and 4.) The solution includes repair and maintenance of street lighting, installation of speed limit signs and reflectors, construction of rumble strips, and installation of accident-prone warning signs and warning lights. It is hoped that this solution can become the basis for targeted special handling to prevent and reduce traffic accidents in the Labuan – Pandeglang Highway area.

Abstract

Floods have a damaging impact on at-risk areas such as areas with relatively high land cover, especially after heavy rains. Land cover is the influence of land use. In land use, the runoff coefficient (C) is a factor that greatly affects the amount of water runoff that occurs during and after rain. The runoff coefficient (C) describes how large the proportion of rainwater that will flow as surface runoff compared to the water that seeps into the soil, so, the closer the coefficient value is closer to the value of 1, the more an area is unable to absorb water, as well as if the runoff coefficient (C) is closer to 0, the more an area can absorb water well. The runoff coefficient (C) has a high correlation with land use. In this study, the variation of runoff coefficient (C) will be simulated on rainfall and area using rational equations and then the results are simulated using HEC-RAS. The variation in runoff coefficient (C) was simulated with the criteria conditions of cultivated land, clay & silt loam soils (C= 0.4) and regional conditions when only able to overflow water or unable to absorb (C= 1). The results were found that the runoff coefficient (C) affects the area and depth of flooding in the study area. At C = 0.4 the maximum flood depth is 2.99 meters in the upstream part of the river and 1.65 meters downstream, while when C = 1, the maximum flood depth is 2.03 meters in the upstream part and 1.1 meters in the downstream part. In this case, it is important to prepare rainwater reservoirs in areas with relatively high land cover or runoff coefficient (C).

Abstract

Dam as water resources infrastructure has inherent failure risks, necessitating regular risk assessments to ensure its safety and functional sustainability. This study aims to evaluate the risk level of Titab Dam using two main methods: Event Tree Analysis (ETA) and the modified Andersen method. Hazard identification was conducted based on the 2024 inspection report, followed by failure mode analysis using FMECA (Failure Mode, Effects, and Criticality Analysis) to determine mitigation priorities. ETA results revealed that both individual and group extreme probabilities exceeded tolerance limits, requiring special interventions for several primary components, especially at the dam crest. Meanwhile, the assessment using the Andersen method produced a safety score of 66.33, categorized as ADEQUATE and still requiring corrective measures for defects found during inspections. This research provides an integration of two methods (ETA and Andersen) to strengthen the validation of dam risk assessment in Indonesia, thereby making the safety evaluation results more comprehensive and reliable. This study emphasizes the importance of implementing risk assessments as part of major inspections and ongoing monitoring activities to minimize failure potential and improve dam safety.

Abstract

The increasing global demand for housing and building materials is creating pressure for sustainable alternatives, driven by the massive generation of construction waste and the use of non-eco-friendly materials. The main purpose of this study was to analyse the characteristics of a composite partition board utilizing basalt rock offcuts with over 96 tons by 2019, and coir fibre waste, which reaches approximately 1.8 million tons annually, as alternative materials. The resulting composite boards were designed to substitute fine aggregate with basalt rock waste and utilized coir fibre as an additive. A key finding is the inverse relationship between coir fibre content and composite density, where the reduction of coir fibre significantly improved the physical properties. Analysis showed that all variations significantly exceeded the minimum requirements specified in the SNI 03-2104-1991 and JIS A 5417-1992 standards for density and dimensional stability. Specifically, the fibre free K2 composition achieved the highest density of 1.87 g/cm3, classifying it as a superior high quality cement board. Furthermore, all compositions demonstrated excellent durability, with impact resistance exceeding 99% mass retention and thermal stability up to 200°C, confirming the composite’s potential as a sustainable, high-performance alternative to conventional partition materials. This study provides a practical contribution to green construction research by validating a localized dual-waste composite that meets international building codes, thereby operationalizing the objectives of SDG 9 and 12 through industrial and agricultural waste utilization.

Abstract

The Earth's average surface temperature has increased immensely, reaching 1.45 +/- 0.12 Celsius in 2023. This is linked to growing carbon emissions from industrial activities, particularly the construction sector. The production of 1 m3 of conventional concrete can emit up to 277.82 kg CO2. Indonesia remains the second-largest asbestos importer, contributing over 100,000 tons annually to the local construction sector in 2023. Most of the waste is unmanaged and causes health concerns. Simultaneously, Bali’s stone carving industry generates approximately 30% basalt stone waste, much of which remains unprocessed and is discarded into rivers or roadside drains. Nationally, Indonesia holds over 1 billion tons of basalt reserves, yet utilization remains low. Addressing these dual environmental issues, this study proposes a sustainable concrete innovation that utilizes 3% asbestos waste as a substitute for cement and 20% basalt waste as a replacement for coarse aggregate. The proposed concrete mix was tested following SNI 03-2847-2002, ASTM C39, and SNI 03-1974-1990. The results show a compressive strength of 44.26 MPa, higher than the required 41.4 MPa for high-strength concrete based on SNI 03-6468-2000. The modified mixture also has a 16.71 percent lower density than normal concrete and a slump value of 157.67 mm, indicating good workability. Furthermore, the mix reduces carbon emissions by 31.273 kg CO2 per m3 and lowers production cost by 43.9 percent, saving IDR 731,401 compared to conventional concrete with similar strength. These innovations show that asbestos and basalt waste can be transformed into low-carbon structural materials, promoting the circular economy while mitigating environmental risks from unmanaged industrial waste.

Abstract

The construction sector in Bali still generates significant environmental waste, including from the tabas stone craft industry, which produces waste equivalent to 30% of the original stone in the form of small pieces and powder. Tabas stone is used as an ornament in traditional Balinese buildings, accounting for 50–80% of the construction material in Bali. This waste is often disposed of in rivers, reducing the wet surface area and polluting the environment. On the other hand, mortar as a binding material in construction accounts for about 30% of total building material use, making the use of environmentally friendly local materials in mortar formulations highly relevant. In 2022, out of 1.02 million tons of waste in Bali, about 70% was organic waste. Most of it came from the construction, agriculture, and handicraft sectors, such as bamboo fiber (BF), coconut fiber (CF), and pineapple leaf fiber (PLF). These materials have high cellulose content, namely bamboo powder at 53.6%, coconut husk at 43.44%, and pineapple leaves at 71.5%, which have the potential to be used as environmentally friendly mortar additives. This study aims to evaluate mortar formulations based on basalt scoria with the addition of these fibers from technical, environmental, and cost-efficiency perspectives. The TOPSIS method from the MCDM approach was used to determine the best formulation based on parameter rankings. The results showed that with the addition of 10% cellulose fibers, the compressive strength obtained was 4.137 MPa for bamboo fibers, 3.224 MPa for coconut husk fibers, and 3.923 MPa for pineapple leaf fibers. The ranking results indicate that while bamboo fiber (BF) shows the highest cost efficiency, the MS-12CCF mixture emerges as the most balanced alternative when considering technical, environmental, and economic aspects.
