Abstract

Urbanization and climate change are expected to exacerbate and introduce uncertainty in future flood characteristics. The city of Denpasar often experiences flooding due to rapid population growth and changes in land use. One form of flood mitigation that can be implemented is infiltration wells. This research aims to design infiltration wells as an environmental conservation effort by evaluating the characteristics of the watershed and the depth of groundwater. This research will also examine lithological aspects and use geographic information systems (GIS) to increase effectiveness in planning. The research results show that the construction of infiltration wells at the research location is effective in reducing flood volume, with reductions varying between 19.86% in South Denpasar and 59.58% in North Denpasar, East Denpasar and West Denpasar. Infiltration wells not only reduce the risk of flooding but also play an important role in preserving the environment according to the Tri Hita Karana concept. By integrating these sustainable practices into spatial planning, water resource management can be enhanced, fostering a healthy environment for future generations.

Abstract

ABSTRACT Rural drinking water management in Buleleng Regency was served by rural drinking water supply (PAM Des) and community-based drinking water supply (Pamsimas). Providing sustainable rural drinking water was the most basic need through the implementation of Tri Hita Karana. Tri Hita Karana (THK) as a sustainability concept greatly determined the success of regional environmental resilience. This research aimed to analyzed strategies for increasing the implementation of Tri Hita Karana in sustainability in the management of PAM Des. Analysis of the sustainability index for PAM Des management used the Multi Dimensional Scaling (MDS) method. Multi Dimensional Scaling also analyzed lever factors that were sensitive to sustainability.The results of the analysis showed that the sustainability index value for the ecological dimension was 70.11%, the economic dimension was 46.00%, the socio-cultural dimension was 50.65%, the technological dimension was 46.89% and the institutional dimension was 49.74%. The sustainability index value for the ecological and socio-cultural dimensions with a value above 50% was quite sustainable. The sustainability index value of the economic, technological and institutional dimensions of the less sustainable category. The leverage factors obtained from the analysis of 5 (five) dimensions of sustainability were 19 factors.The strategy to increased the implementation of Tri Hita Karana in the ecological and socio-cultural dimensions was the implementation of mutual exchange between PAM Des managers and land owners of springs, implementation of magpag toya upakara, tumpek wariga, community participation in PAM Des, use of water according to needs, adjustment of the level of community water needs and community concern for PAM Des infrastructure. In the economic, technological and institutional dimensions, this must be done by improving, improving the PAM Des infrastructure and also regulations that strengthened the management of PAM Des. The strategy to increased the implementation of Tri Hita Karana had had a positive impact on environmental resilience in the management of rural drinking water supplies in Buleleng Regency, Bali.

Abstract

Flood is a natural phenomenon that often occurs in several areas of Badung Regency. Losses result in damage to buildings, roads, and other public facilities. Floods are caused by a more sloping land topography, changes in land use to dense settlements, and soil conditions. This study aims to deal with flooding by evaluating the existing canal on Jalan Kunti II Seminyak. The method used for testing data consistency is the RAPS (Rescaled Adjusted Partial Sums) method. The distribution used is Log Person Type III. Testing of frequency distribution used the Smirnov – Kolmogorov Test and the Chi-Square Test. Analysis of rainfall intensity using the Mononobe formula. Calculation of planned flood discharge (Q) uses the Rational method, Nakayasu method, and theoretical discharge control for 2, 5, 10, and 25-year return periods with the existing channel capacity. The result of the analysis shows that the theoretical discharge with a return period has met of planned flood discharge so that the drainage on Jalan Kunti can accommodate the planned flood with a return period of 10 years. Where the drainage capacity of Jalan Kunti is 0,412 m3/second & 0,461 m3/second. The drainage ditch with a capacity of 200 m3/second to Tukad Mati has not been able to accommodate the planned flood discharge for the 25-year return period of 242.33 m3/second. The Tukad Mati channel for the existing Q 675,825 m3/second has been able to accommodate the flood discharge Q at the 25-year return period of 314.49 m3/second.

Abstract

The Bili-Bili Reservoir serves multiple purposes, including flood control, raw water supply, irrigation, and hydropower generation. In 2021, significant discrepancies were observed between the Annual Reservoir Operation Plan (AROP) and the actual Reservoir Operation Pattern (ROP). during the first 15 days of December 2021, the AROP targeted a rest water level (RWL) of +77.34 m with a planned discharge of 20.27 m³/sec. In contrast, the realized RWL reached +92.35 m with an actual discharge of 45 m³/sec. This study aims to analyze the causes of these differences and compare the reservoir operations outlined in the AROP with those reflected in actual utilization, using an operational pattern simulation based on variations in irrigation water requirement (IWR). Analysis using a dependable flow of 80% shows that the total IWR in the AROP is only 69% of the IWR calculated from actual reservoir utilization, likely due to declining inflow trends and an operational pattern that adjusts to inflow magnitude and rainfall. Meanwhile, the realized IWR is 32% greater than the utilization analysis and 91% greater than the AROP, indicating that the reservoir released more water than planned, following actual inflow conditions. This study highlights the need for more adaptive reservoir operation planning to ensure effective water resource management.

Abstract

River bend erosion is a major concern for river engineers because it affects channel stability and navigation safety. Erosion along the outer bank and deposition along the inner bank are the primary processes responsible for the meandering pattern of rivers. This study investigates the effect of discharge variations on scour depth in a meandering reach of the Bogowonto River using numerical modeling with HEC-RAS 6.6. Simulations were carried out for six discharge scenarios corresponding to return periods of 2,5, 10, 20, 50, and 100 years (Q2, Q5, Q10, Q20, Q50, and Q100). The historical rainfall data collected from 2002 to 2021. Limantara Unit Hydrograph used for rainfall-runoff modelling. The HEC-RAS simulation results of the 2-year return period (Q2) reveal that sedimentation occurs at five points along the Bogowonto River bend in Purworejo District. In particular the greatest accumulation occurred at the apex of the bend (STA 17), where the bed sediment thickness reached 4.175 m at the Q100 discharge. The simulation results show a uniform sedimentation pattern across the entire bend cross-section, likely due to model limitations that prevent detailed representation of cross-flow patterns.

Abstract

Sungai merupakan salah satu bentuk infrastruktur sumber daya air, selain mengalirkan air, sungai juga kerap mengangkut sedimen. Sedimen merupakan hasil dari erosi dan ini menjadi salah satu permasalahan pada aliran sungai. DAS Unda memiliki cakupan wilayah cukup luas, sehingga erosi yang menyebabkan sedimentasi pada aliran Tukad Unda diperkirakan cukup besar. Penelitian ini menganalisis berat total sedimen yang mengendap pada bagian hilir Tukad Unda dan membandingkan analisis sedimentasi metode Universal Soil Loss Equation (USLE) dengan metode analisis sedimentasi dalam HEC-RAS dengan bantuan aplikasi ArcGIS dan HEC-GeoRAS untuk menggambarkan bentuk profil tampak atas dari sebaran sedimen yang terbentuk, serta upaya dalam menanggulanginya. Data yang digunakan adalah luas DAS, jenis tanah, hujan serta debit aliran sungai. Metode yang digunakan adalah metode USLE dan aplikasi HEC-GeoRAS dan ArcGIS. Hasil penelitian menunjukkan rata-rata erosi yang tejadi dalam 10 tahun terakhir adalah sebesar 30,57 ton/ha/tahun, kemudian hasil dari analisis HEC-GeoRAS didapatkan perubahan profil aliran dasar sungai mengalami pendangkalan cukup signifikan yaitu sebesar 2.365 m3 dengan meggunakan aplikasi, dan 2.654 m3 dengan metode USLE. Upaya penanggulangan dapat dilakukan dengan menormalisasi dasar sungai dengan pengerukan secara berkala pada titik stationing UD 64-60, pada titik stationing UD 55-57 dan pada stationing UD 45-41 sesuai dengan hasil analisis yang didapat melalui aplikasi HEC-GeoRAS.
