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

Abstrak.Data curah hujan yang akurat, reliabel, dan mendekati waktu nyata adalah faktor penting dalam analisis peramalan dan mitigasi bencara alam hidro klimatologi (banjir, tanah longsor, topan, dan curah hujan ekstrim), pemodelan hidrologi, prakiraan cuaca, perencanaan pertanian, manajemen ekologi, dan manajemen sumber daya air. Observasi curah hujan stasiun menghadapi kendala di Provinsi Bali, terutama pengukuran jarang ditemui di daerah terpencil dan pegunungan. Oleh karena itu, perlu mencari sumber data hujan yang dapat diandalkan seperti produk hujan berbasis satelit, yang menyediakan data dalam waktu mendekati waktu nyata (near real-time), deretan waktu hujan yang tidak terputus dengan resolusi spasial tinggi. Penelitian ini mengevaluasi kinerja produk hujan satelit global yang mendekati waktu nyata dengan 43 stasiun di Provinsi Bali. Produk curah hujan satelit yang dianalisis adalah Integrated Multi-satellitE Retrievals for Global Precipitation Measurement-Early Run (IMERG-ER) dan The Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks - Dynamic Infrared Rain Rate near real-time (PDIR-Now). Selanjutnya, kedua data curah hujan berbasis satelit tersebut dikoreksi menggunakan tiga pendekatan, yaitu koreksi rasio bias, koreksi rata-rata deviasi, dan koreksi nilai fungsi distribusi probabilitas. Metode tradisional berbasis titik ke piksel bersama dengan pengukuran statistik kontinu, metrik kategoris, serta indeks volumetrik diimplementasikan untuk mengevaluasi kinerja produk satelit. Studi ini menunjukkan bahwa meskipun kedua dataset memiliki kelebihan masing-masing, IMERG-ER cenderung lebih konsisten dan andal dalam berbagai kondisi dibandingkan PDIR-Now, terutama setelah koreksi dilakukan. Koreksi nilai fungsi distribusi probabilitas menunjukkan peningkatan kinerja paling signifikan dibandingkan dengan metode koreksi yang lainnya. Hasil studi ini juga mempertegas bahwa koreksi kesalahan perlu dilakukan sebelum data curah hujan berbasis satelit diaplikasikan dan berbagai bidang.Abstract. Accurate, reliable, and near-real-time rainfall data are critical factors for forecasting and mitigating hydro-meteorological natural disasters (such as floods, landslides, typhoons, and extreme rainfall), hydrological modeling, weather forecasting, agricultural planning, ecological management, and water resource management. Rainfall observations from station measurements face challenges in Bali Province, particularly due to the scarcity of measurements in remote and mountainous areas. Therefore, it is necessary to seek reliable sources of rainfall data, such as satellite-based rainfall products, which provide near real-time data, uninterrupted rainfall time series, and high spatial resolution. This research evaluates the performance of global near real-time satellite rainfall products with data from 43 stations across Bali Province. The satellite rainfall products analyzed include the Integrated Multi-satellite Retrievals for Global Precipitation Measurement-Early Run (IMERG-ER) and the Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks - Dynamic Infrared Rain Rate near real-time (PDIR-Now). Subsequently, the satellite-based rainfall data were corrected using three approaches: bias ratio correction, mean deviation correction, and probability distribution function value correction. Traditional point-to-pixel methods, along with continuous statistical measurements, categorical metrics, and volumetric indices, were implemented to evaluate the performance of satellite products. The study reveals that although both datasets have their respective strengths, IMERG tends to be more consistent and reliable under various conditions compared to PERSIANN, especially after corrections are applied. The probability distribution function value correction demonstrated the most significant performance improvement compared to the other correction methods. The findings of this study also emphasize the necessity of error correction before satellite-based rainfall data is applied across various fields. Submitted: 2024-09-14 Revisions:  2025-03-06 Accepted: 2024-09-11 Published: 2025-03-14

Abstract

Baturinggit Road is one of the main routes for shipping goods/materials involving overloaded vehicles. The more vehicles that pass, the greater the load that passes through the road, resulting in road damage. The purpose of this study was to analyze the remaining life of the road design caused by overloaded vehicles. The study was conducted for 3 days, starting from April 15, 2024 - April 17, 2024 at 08.00 WITA - 18.00 WITA on the Baturinggit Road section, Kubu District, Karangasem Regency, Bali Province. Based on the results of the study, it is known that the cumulative Vehicle Damage Factor (VDF) of normal loads during the 10-year Remaining Life (RL) is 10,658,570 ESAL while the cumulative VDF of excess loads during the 10-year RL is 28,727,670 ESAL. Based on calculations using the AASHTO 1993 method, the magnitude of the RL decrease that occurred was 291%, meaning that there was a decrease in RL of 7.45 years so that the percentage of cumulative VDF increase due to overloading was 169.53%. The percentage of vehicles with overloading that caused damage on the Baturinggit Road section included pickup trucks of 30%, light trucks of 59.80%, medium trucks of 119.52%, heavy trucks of 10% and 1.2-2 trailer trucks of 19.08%. The conclusion from the calculation results of the AASHTO 1993 method was a decrease in RL of 291% or equivalent to a loss of road life of 7.45 years from the initial design life. The impact of overloading on medium trucks is the focus of attention because of its very significant contribution to road damage.

Abstract

Wood material is a construction material that has its own appeal from an aesthetic and architectural point of view, however wood material has various limitations, namely in terms of durability and structural strength when compared to structural materials such as concrete and steel. This research examines the structural behavior of residential houses using glulam wood materials using program analysis software ETABS.  From the results of initial design calculations, the dimensions of the structural elements were obtained, namely beams measuring 25 cm x 40 cm and columns measuring 30 cm x 30 cm. Based on the results of the analysis that has been carried out, it shows that the house structure has met earthquake resistance requirements with maximum inter-story drift of 24.35 mm (below the 26.92 mm limit). The dynamic analysis shows successful mass participation with total mass participation ratios exceeding 90% in all primary directions: 99.11% for translational motion in X-direction (UX), 99.29% for translational motion in Y-direction (UY), and 99.51% for rotational motion about vertical axis (RZ). These results indicate that the structural model adequately captures both lateral and torsional responses of the building under seismic loading.

Abstract

The construction of health care facilities, such as Community Health Centers (Puskesmas), requires efficient cost planning given the limited local government budget. One approach to optimizing costs without reducing the building's function and quality is value engineering. This study aims to apply the value engineering method to the construction project for the UPTD Puskesmas III Building of the West Denpasar District Health Office to identify work items with potential for cost efficiency and to analyze the savings that can be achieved. The research method uses a case study approach with a value engineering work plan that includes the information stage, function analysis, creative stage, analysis stage, development stage, and recommendation stage. The analysis was carried out using breakdown cost analysis, cost-benefit ratio, life-cycle cost (LCC), and the Analytical Hierarchy Process (AHP). The results of the study indicate that work items such as floor slabs, doors and windows, ceramic floors and walls, and wall masonry and plastering have the greatest potential for value engineering. The implementation of the selected alternative resulted in a total cost savings of Rp1,308,373,475.75 or 7.67% of the total initial project cost. These results indicate that value engineering is effective in increasing construction cost efficiency without reducing the building's function or quality, making it suitable for application in health care facility construction projects.

Abstract

When planning a tall building structure, the deviation due to lateral forces is very important to be taken into account in the planning of tall building structures. To reduce the amount of deviation in the structure adding by special structural elements, as shear walls. With the shear wall, can increase the stiffness of the building structure and absorb large shear forces along with higher the building structure and lateral force on structure will not fully accepted by frame structure which will result a decrease in deviation. Guestwing 1 The Ritz Carlton Hottel located in South Kuta District, Badung Regency, Bali. This building has a height of 20.2 m consisting of 6 floors. Planning with 2 models: a) SRPMK Existing Modeling, b) Dual System Model. Material specifications and loading are the same, just different in addition of shear walls and reducing the dimensions the building. Based on the results the analysis of the two models, the largest inter-storey deviation value in the existing model X=52.014mm; Y=47.960mm and for the dual system model X=25.614mm; Y=26.026mm. From the results of deviation analysis on both models, can be concluded that with addition of shear walls, there is a decrease in deviation 63.27% in X direction and 68.18% in Y direction. The most significant decrease occurs in dimensions and reinforcement of column K1 from size 350x800mm with 22 D22 reinforcement to column 300x600mm with 18 D22 reinforcement, beam B3 250x450mm for support area 17 D13 and field area 10 D13 to beam 250x400mm with the number of support reinforcement 11 D13, and the number of field reinforcement 7 D13. From the results of this planning can be used as a consideration for the construction of the next building for the use of shear walls in the structure.
