The increasing water demand due to population growth and territorial expansion has significantly outpaced the natural water supply in Sungai Pinyuh, Kalimantan Barat. This sub-district, part of the Mempawah Regency, faces challenges such as insufficient access to clean water, deteriorating pipe infrastructure, and environmental pollution affecting water quality. To address these issues, a study has been undertaken to plan a comprehensive development of the drinking water distribution system in Sungai Pinyuh, guided by the Regional Regulation of Mempawah Regency No. 3 of 2014. The planning utilizes EPANET software, a tool developed by the U.S. Environmental Protection Agency (EPA), which allows for the simulation of dynamic conditions in the water distribution system. EPANET helps create detailed maps of the pipe network, determine pump and reservoir locations, and specify pipe characteristics. The software’s ability to simulate various scenarios, such as changes in demand or disruptions, is crucial for ensuring a reliable water supply. The analysis incorporates primary data from field observations and secondary data from population statistics and existing water supply documents. The proposed distribution system will employ HDPE pipes of various diameters and a pump with a capacity of 200 L/s and a head of 5 meters. Simulation results indicate that the system's velocity, ranging from 0.3 to 0.72 m/s, and other parameters, such as head loss and pressure, are within acceptable limits. Additionally, reservoir capacity planning is based on the maximum daily water demand, with a calculated capacity of approximately 3,347.839 m³ to ensure adequate supply. This study provides a strategic framework for improving the drinking water distribution system, addressing current deficiencies, and preparing for future needs.

This study examined the impact of different threshold widths and channel narrowing configurations on water flow characteristics. The research involved testing three threshold widths (AL1, AL2, AL3) and six narrowing models (PM10, PM15, PM20, PT10, PT15, PT20) with varying water heights (1.0 cm, 1.5 cm, and 2.0 cm) above the threshold. Results indicated that narrowing at the upstream end increased water levels upstream and downstream, with a corresponding rise in flow velocity at the downstream end. Discharge values and coefficients varied significantly across different configurations, with non-linear increases observed in discharge coefficients due to changes in water levels and velocities. Scaling calculations provided prototype channel dimensions and flow characteristics, highlighting the study's strengths in using a fiberglass open channel and diverse testing configurations. However, limitations include the laboratory scale and exclusion of channel roughness effects.

Representative Mock Model Parameters for Generating Monthly Discharge Curves in the Upper Kapuas River Basin provide valuable insights into hydrological processes influenced by climatic factors. Potential evapotranspiration peaks in August due to elevated temperatures and intensified sunshine during the 2005 dry season, leading to increased water demand from soil and vegetation. This results in heightened water loss to the atmosphere, reducing available water for river flow and decreasing monthly discharge, which is crucial during dry periods. Effective water resource management strategies are essential to mitigate potential water scarcity. High rainfall in the upstream Kapuas watershed significantly impacts monthly discharge, with increased surface flow directly boosting river discharge. The monthly discharge varies widely between rainy and dry seasons, notably rising during heavy rainfall, potentially causing flooding. Effective watershed management, including runoff management, reforestation, and infrastructure development, is critical to mitigate these impacts and optimize water resources for irrigation and supply, ensuring efficient utilization of increased rainfall. Correlation and RSR test results underscore the model's ability to capture variable relationships and predict outcomes accurately. Strong correlations between 0.8 to 1 and RSR values ranging from 0.5 to 0.7 demonstrate the model's reliability in various scenarios. Models with lower RSR values below 0.5 exhibit exceptional prediction accuracy, emphasizing their utility in diverse applications. These findings highlight the importance of refining models to enhance accuracy and reliability in predictive hydrological applications within the Upper Kapuas River Basin, ensuring adequate water resource management and flood risk mitigation.

The study, titled "Flow Hydrograph Generation for Melawi Sub-Watershed Using the Snyder Synthetic Unit Hydrograph Model," investigates the hydrological response of the Melawi Sub-Watershed in West Kalimantan to rainfall events using the Snyder Synthetic Unit Hydrograph Model (SUHM). This model, instrumental in areas with limited hydrological data, is well-suited for the Melawi Sub-Watershed. The analysis uncovers a peak discharge (Qp) of 13.671 m³/sec with a time to peak (Tp) of 88.905 hours, highlighting the region’s susceptibility to prolonged rainfall. The model’s parameters, such as Ct and Cp, are used to generate accurate flow hydrographs, which are essential for flood management. The results show varying design discharges for different return periods (Q2 to Q100), providing critical data for flood risk mitigation and infrastructure planning. This research underscores the SUHM's effectiveness in flood forecasting and sustainable development, aiding in resilient flood management strategies and informed infrastructure design in the Melawi Sub-Watershed. The findings of this study also pave the way for future research in hydrology and flood management.

This research addresses the complexities of treating brackish and seawater from Sungai Itik using Reverse Osmosis (RO), emphasizing advanced pre-treatment methods, hybrid RO systems, and fouling control. Pilot-scale tests confirmed the feasibility of these approaches in meeting clean water standards and balancing economic and environmental sustainability.Using a single ultra-low pressure (ULP) RO membrane, salinity decreased by 57.36%, Total Dissolved Solids (TDS) by 25.76%, and watercolor by 63.25%, achieving improved water quality. Expanding to a ULP and Brackish Water (BW) membrane combination further reduced salinity by 40.63%, TDS by 35.76%, and watercolor by 92.13%, highlighting the benefits of hybrid systems for varied water conditions. In seawater treatment, a ULP membrane reduced salinity by 69.48%, TDS by 93.49%, and watercolor by 97.74%, proving effective for converting seawater to potable or industrial-grade water. Combining ULP and BW membranes achieved salinity reductions of 94.67%, TDS by 94.02%, and watercolor by 34.94%, which is crucial for applications needing ultra-clean water. These findings underscore RO's potential to mitigate water quality challenges and support sustainable water management in diverse environments.

Abstract Floods in the Toli-toli area often occur due to the continued reduction in infiltration land. Flood events from year to year have a bigger impact and cause a lot of losses. The impact of this flood needs to be analyzed and its magnitude predicted so that the potential for flooding can be estimated. Flood handling can be addressed early on so that when a flood the losses are not so great. Flood prediction can be done by hydrological analysis using HEC HMS 4.5 and continued hydraulics using HEC RAS 5.0.3. Based on the incidence of rain over the last 10 years, it is known that the return period of rain in the Toli-toli area varies from a period of 2 years, 5 years, 10 years, and 15 years. Based on the calculation results, it is known that the flood in the Toli-toli area in the 2-year return period has a depth of 0.66 meters with a flood inundation area as shown in Figure 7 of this article. In overcoming this flood, efforts should be made to handle it with several alternatives such as increasing infiltration land, normalizing rivers, and so on.

This study investigates the optimization of project scheduling using the Critical Path Method (CPM) in construction projects. Focusing on the Building Rehabilitation Project, Dekranasda Hall, and Kalimantan Barat Museum Fence, the research aims to reduce project duration without altering costs. CPM is employed to map out activities in a network, identifying the critical path to enhance time management. The initial project duration was 249 days. By breaking down work items and increasing the number of workers in critical activities, the duration was reduced to 125 days. Optimization involved dividing tasks into manageable segments and determining the appropriate workforce through trial and error. The study demonstrates that effective project scheduling and resource allocation can significantly reduce completion time, highlighting CPM's value in project management for achieving efficiency and meeting deadlines. The findings emphasize the importance of detailed planning, dependency logic, and continuous monitoring to optimize construction project timelines.

Pervious concrete is one of the alternatives to prevent flooding during the rainy season. Because of the large number of pores produced by the absence or use of fine aggregate in its production, previous concrete has a poor compressive strength. This study focuses on the size and manner of compaction of coarse aggregates to boost the compressive strength of previous concrete. It is essential to address the void content in this process. The research started by analyzing the materials used to make the previous concrete mix. The next step was to determine the void content, plan the mix design, make the mix, treat the concrete, and finally test it using various methods such as volume weight, compressive strength, porosity, and permeability tests. Research shows that a three-layer perforated variation on a 0.5/0.5 cm coarse aggregate with a compressive strength of 21.04 MPa, volume weight of 1896.674 kg/m3, permeability of 0.597 cm/s, and porosity of 16.232% yields the best results. Although 24 MPa was the intended compressive strength, previous concrete fell short due to the paste content used in the compaction method. In addition, the volume weight is lighter than the plan, and the permeability and porosity are more significant than the plan. The relationship between aggregate size and compaction method is based on the graph of the effect of void content and paste content, which shows that the greater the paste content, the smaller the void content produced.

Because of the large number of pores produced by the absence or use of fine aggregate in its production, previous concrete has a poor compressive strength. This study focuses on the size and manner of compaction of coarse aggregates to boost the compressive strength of previous concrete. It is essential to address the void content in this process. The research started by analyzing the materials used to make the previous concrete mix. The next step was to determine the void content, plan the mix design, make the mix, treat the concrete, and finally test it using various methods such as volume weight, compressive strength, porosity, and permeability tests. Research shows that a three-layer perforated variation on a 0.5/0.5 cm coarse aggregate with a compressive strength of 21.04 MPa, volume weight of 1896.674 kg/m3, permeability of 0.597 cm/s, and porosity of 16.232% yields the best results.

Penerapan BIM di Indoensia perlu dianalisis dan dievaluasi agar dapat menciptakan penggunaan BIM yang lebih efektif dengan mengacu kepada standar protokol yang telah dibentuk oleh kementerian PUPR. Proyek yang ditinjau adalah proyek Universitas Nahdlatul Ulama Yogyakarta yaitu proyek percobaan yang menerapkan BIM dengan pedoman Dokumen Protokol BIM Kementerian PUPR 2020. Penelitian yang dilakukan adalah menganalisis tingkat kepentingan dan tingkat kinerja faktor pelaksanaan BIM pada proyek untuk menentukan prioritas kebijakan dan evaluasi yang perlu dilakukan dengan menggunakan metode Importance Performance Analysis. Selanjutnya, dilakukan juga analisis kesesuaian penerapan BIM pada proyek terhadap standar protokol BIM Kementerian PUPR tahun 2020. Dari 15 faktor penerapan yang ditinjau, kedua analisis tersebut memberikan hasil yaitu terdapat enam faktor yang pelaksanaannya sudah sesuai. Didapatkan juga hasil bahwa sejumlah faktor dievaluasi berlainan oleh tim pelaksana BIM antara sifat kuadran dan kesesuaiannya. Hal tersebut mengindikasikan adanya pemahaman terhadap standar protokol yang belum menyeluruh. Sehingga dibutuhkan adanya sosialisasi terkait dengan pelaksanaan BIM menurut standar protokol BIM Kementerian PUPR tahun 2020 oleh Kementerian PUPR untuk seluruh disiplin proyek.
