Abstract

Banjir merupakan masalah yang sering terjadi di area perkotaan, tidak terkecuali Kota Denpasar, Bali. Denpasar menduduki peringkat ketiga di Provinsi Bali untuk kejadian banjir dengan tujuh kali kejadian atau 16% dari total insiden di daerah tersebut. Topografi landai serta curah hujan tinggi (sekitar 1800 mm per tahun) menjadi penyebab masalah banjir di Denpasar, yang diperburuk oleh kapasitas sistem drainase yang belum mencukupi, pengurangan resapan air hujan akibat pembangunan yang intensif, dan kekurangan ruang terbuka hijau. Penelitian ini membahas pembangunan Embung Sanur sebagai solusi konservasi air metropolitan yang selaras dengan konsep kearifan lokal Bali, Tri Hita Karana. Melalui metode DMAIC, didukung dengan studi literatur, riset ini mengevaluasi desain dan efektivitas Embung Sanur. Kefektifan dinilai dari kontribusi pada pengembangan perkotaan dan sosial ekonomi yang berkelanjutan, sesuai dengan inovasi era Society 5.0. Studi ini bertujuan meningkatkan kualitas hidup manusia secara berkelanjutan dan memenuhi tujuan Pembangunan Berkelanjutan (SDGs) terkait dengan Industri, Inovasi, dan Infrastruktur keairan. Kesimpulan menunjukkan kemungkinan replikasi efisiensi Embung Sanur di kota lain dengan kondisi hidrologi dan geografis serupa.

Abstract

Subak Pulagan yang berada di Daerah Irigasi Pulagan Kumba ini telah ditetapkan oleh UNESCO menjadi Warisan Budaya Dunia (WBD). Subak Pulagan mendapatkan sumber air dari Bendung Pulagan yang terletak di Daerah Aliran Sungai (DAS) Pakerisan. Menurut Pekaseh Subak Pulagan, setiap tahunnya sebanyak 0,36% terjadi perubahan fungsi lahan pertanian yang diakibatkan dari penurunan kuantitas debit. Tujuan penelitian ini adalah untuk mengetahui ketersediaan air dengan dua metode hujan aliran yaitu F.J Mock dan metode Modifikasi Thornthwhite Mather dan kebutuhan air irigasi saat musim kemarau dan musim hujan di Subak Pulagan. Selanjutnya dapat ditinjau neraca air yang dihasilkan dari analisis tersebut. Verifikasi model hujan aliran dilakukan terhadap pengukuran debit nyata pada intake Bendung Pulagan dengan menggunakan metode uji kesamaan dua rata-rata. Hasil model hujan aliran memiliki trend hampir signifikan satu dengan lain. Hal ini dipengaruhi oleh kondisi hidroklimatologi DAS Tukad Pakerisan. Saat dibandingkan dengan data debit intake Bendung Pulagan yang memiliki grafik relatif konstan dalam periode tertentu, maka dapat dikatakan kedua model hujan aliran dapat mewakili kondisi ketersediaan air pada Bendung Pulagan. Berdasarkan neraca air antara debit intake Q80 Bendung Pulagan dengan Kebutuhan Air Irigasi didapatkan hasil surplus air untuk setiap periode. Selanjutnya uji verifikasi model menggunakan uji kesamaan dua rata-rata dari tahun 2014 hingga tahun 2017, dan mendapatkan nilai t Hitung (tH) masing-masing sebesar -0,14; -0,19; 0,138; 0,108; -0,88; -1,301; -0,671 dan -0,84. Nilai tersebut dapat diterima ke dalam grafik daerah penerimaan model dengan persamaan , sehingga dapat disimpulkan bahwa kedua model hujan aliran ini dapat diaplikasikan pada DAS Tukad Pakerisan

Abstract

The Irrigation Area (D. I.) Mambal, which passes through Badung Regency, Denpasar City, and Tabanan Regency, is the largest irrigation water supplied by the Ayung River, covering an area of 5.963 Ha. Despite the Ayung River’s substantial water potential, the D. I. Mambal experiences water shortages during certain months. This research aims to improve the effectiveness and efficiency of irrigation water use based on the Global Planting Management Plan (RTTG) using simulation methods and dynamic program optimization. Simulations were carried out under low conditions, normal and sufficient dependable discharges, using both existing and alternative RTTG. The objective function of the dynamic optimization seeks to maximize revenue gain from the applied RTTG. The existing cropping pattern at the beginning of planting in October showed an average proportion of fulfillment of water irrigation needs at 85%. Under the Alternative I condition, with planting beginning in November, the average proportion of fulfillment of irrigation water needs was 89%. In Alternative II conditions, with planting beginning in December, the average proportion of fulfillment of irrigation water needs was 87%. By optimizing the water discharge using the dynamic program, the irrigation profit for the existing cropping pattern (October) amounted to IDR 491,816,154,938. The highest profit was obtained using the Alternative II cropping pattern (December), totaling IDR 606,675,369,830. Meanwhile, the lowest profit was obtained in the Alternative I cropping pattern (November), which was IDR 360,767,292,361. The analysis showed that the Alternative II cropping pattern, starting with the first rice planting period in December, yields the most optimal results. The analysis considers the optimized air allocation and irrigation benefits obtained from the third cropping pattern.

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.
