Abstract

Construction projects are a series of activities that are typically one-time and short-term. Ongoing projects often experience delays, both in terms of completion time exceeding the plan and implementation costs being higher than those projected in the Implementation Budget Plan (RAP). Deviations from the plan must be continuously measured to control costs and time. Ineffective project management is marked by significant deviations in costs and time. The purpose of this research is to evaluate the performance of the Warmadewa University Educational Building construction in terms of cost and time using the Earned Value Method, and to identify solutions to address delays. Additionally, to determine the economic value of a building based on its operational costs throughout its lifespan, Life Cycle Cost (LCC) is used in this study. This research employs a descriptive method with a quantitative approach, utilizing necessary data such as plan drawings, RAB, time schedules, and weekly reports. The performance analysis results show an SPI value of 0.81, indicating that the project is delayed from the planned schedule. Meanwhile, the CPI value is 1, meaning that the work is in line with the planned budget. If project performance remains stable until completion, the estimated total cost (EAC) will match the plan at IDR 23,948,882,427.62. The estimated project time (EAS) is longer than the initial plan, from 380 days to 428 days, indicating an extension of 48 days. Using LCC calculations for the Warmadewa University Educational Building project, the total maintenance cost for wall, floor, and ceiling work is IDR 19,403,342.58.

Abstract

Aim: This research focuses on understanding the extent of rice field loss and the corresponding increase in non-agricultural land to promote sustainable land management and planning. It examines the significant land-use changes in the Jepun Pipil Region, Kesiman Village, Bali, from 2013 to 2024, with a focus on rice fields and non-rice fields. Methodology and results: The study utilizes remote sensing technology and Landsat satellite imagery, applying four vegetation indices (NDVI, EVI, SAVI, and LAI) to analyze temporal changes in land cover. Among these, NDVI proved to be the most effective index for monitoring the transformations. The analysis shows a notable reduction in rice fields, particularly between 2023 and 2024, with a 43.48% decrease due to urban expansion and infrastructure development. Conversely, non-rice fields expanded by 130.43% during the same period, driven by the increasing demand for residential and commercial areas. Conclusion, significance, and impact study: The study highlights the importance of sustainable land-use planning and urges policymakers to strike a balance between development and the conservation of agricultural lands. The findings provide critical insights for local governments and stakeholders in land management and urban planning, contributing to wider efforts in monitoring agricultural land use and shaping effective policy strategies.

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

The performance-based concept for earthquake-resistant buildings must be considered in the structural design of buildings. This concept analyzes the structural components to observe how the structure behaves during an earthquake, ensuring the building can withstand it safely. This study used pushover analysis to compare the performance of buildings with and without shear walls. The building's structure was constructed using three different types of modeling. The results showed that type 1 buildings have greater displacement and story drift values than type 2 and type 3. This finding suggests that type 2 and type 3 buildings had better structural rigidity than type 1. The plastic hinge mechanism in type 1 buildings refers to the SCWB design concept, where the plastic hinge mechanism occurs on the beam, whereas in type 2 and type 3 buildings, the plastic hinge machinery occurs in the shear wall area. Performance levels in types 1, 2, and 3, which use the FEMA 356 method, are at the immediate occupancy performance level.

Abstract

As the height of a building structure increases, the building becomes more vulnerable to responding to lateral loads, which is why a dual-system approach is used to resist the lateral forces that occur in the structure. The use of moment-resisting frame systems (MRF) and dual systems differs particularly in terms of earthquake loads. Based on these conditions, an analysis was performed to compare the effects of loading on a frame system versus a dual system in the structural design of the RSU BaliMed Negara building. In the modeling process, two models were created: Structure 1 represents the existing condition, and Structure 2 incorporates the addition of shear walls. The analysis results show that the 100% mass participation value for Structure 1 is achieved at mode 34, whereas for Structure 2, it decreases to mode 15. The natural period of vibration is also influenced by the structural loading, with the addition of shear walls resulting in a shorter natural vibration period for Structure 2 compared to Structure 1. The base shear forces for Structure 1 are Vd in the X and Y directions at 4,856.70 and 4,856.41, respectively, and Vs in the X and Y directions at 4,635.12. For Structure 2, the values are Vd in the X and Y directions at 4,745.47 and 5,745.43, and Vs in the X and Y directions at 5,508.07. The displacement values for Structures 1 and 2 indicate that the displacement in Structure 2 is smaller.

Abstract

The rapid urbanization and tourism growth in Denpasar City, Bali, have led to increasing waste management challenges. Currently, only 22% of the daily 850 tons of waste is managed at the source, with the rest transported to landfills. This study aims to evaluate the implementation of Waste-to-Energy (WES) incineration systems as a potential solution to both waste disposal and energy production. The research uses a quantitative method involving primary data collection through interviews and secondary data from existing documentation. Three incinerator designs were analyzed based on parameters like energy efficiency, emissions, and environmental impact. The results show that the third incinerator system delivers the highest power output at 445.67 KW, although it also produces moderate pollutant emissions. The second design system, however, strikes a better balance, offering both lower emissions and effective power generation, making it the most environmentally favorable option. The study contributes to the growing body of research on WES technology, highlighting the need for advanced design optimization to minimize environmental impacts while maximizing energy output.

Abstract

Penimbangan Beach, located in Bakti Seraga Village, Buleleng, has functioned as an area for fishermen to catch fish but has now been changed to become a tourism destination. The coastline of Penimbangan Beach is 803 meters, according to direct measurements with coastal protection sea wall along the shoreline in the field. With the change in function, many traders’ kiosks are now selling on the sea wall, and coastal protection has caused damage. Besides that, wave overtopping often occurs during high tides, causing objects that should be protected by the sea wall to be exposed to wave overtopping. Based on the issues mentioned above, a coastal damage assessment is required, divided into 16 segments, each segment being 50 meters. The results of the coastal damage assessment yielded the scales of Priority C (preferred), Priority D (less prioritized), and Priority E (not prioritized). The result of evaluating the physical condition of all of the sea walls received fairly good results. The performance function of the coastal protection at Penimbangan Beach shows that segments 1-5 have good functional performance, requiring only monitoring of the sea wall. However, segments 6-16 have poor functional performance due to wave overtopping, necessitating a reassessment of the sea wall.
