Abstract

In addition to its benefits as a means of fulfilling water needs, springs in Bali Province also play a role in religious activities in Bali. Religious rituals that utilize springs as a means are melukat. Melukat is a self-cleansing ritual that is currently popular as religious tourism offered by several spring areas in Bali. Yeh Jepun Spring located in Sibetan Village is used as a source of clean water for the surrounding community. The condition of the spring is currently threatened by flooding that occurs in the river so spring protection is needed. This activity is carried out by designing protection and arrangement of springs to be able to provide added value to the spring area. The implementation of the activity begins with the implementation of a survey in the form of a topographic survey, discharge measurement survey, and water quality testing. The results of this activity are embankments surrounding the spring, spring boundaries and the arrangement of springs.

Abstract

This climate change impacts the coast of Indonesia, which causes erosion and tidal flooding. This coastal damage significantly affects vital areas in the form of tourist areas, such as on the south coast of Bali. The erosion rate on Bali's beaches currently reaches 2 m/year and dramatically impacts the existence of beach tourism objects in Bali. Seawalls and revetments dominate coastal protection structures built from the 1990s. The existing system is experiencing problems, namely tidal flooding and runoff at the building's crest. The method analyzes sea-level changes over time (time series) and numerical simulations with CMS-Wave to obtain wave heights in the structure. Extreme water level (Extreme Coastal Water Level) is calculated from the creep due to wave height, sea level rise, tides, and storms. The results of this study indicate that the rising water level in 2022 will cause 53.80% of buildings to experience overtopping. In the next 20 years (2042), the percentage of buildings experiencing overtopping will increase to 67.08%.

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

This study aims to map the collective identity of the people of Tumbu Village, Karangasem, Bali, using historical approaches, cultural landscape studies, and an analysis of customary rules. The primary data are sourced from 13th-century inscriptions such as the Ruk-ruk, Pasemetan, and Tumbu Puseh Inscriptions, along with awig-awig (local customary laws) that remain actively implemented. The research applies a descriptive-qualitative method through field observations, literature reviews, traditional document interpretation, and participatory interviews with community leaders and local residents. The findings reveal that the collective identity of Tumbu Village is shaped by the integration of historical values, agrarian landscapes, the Hindu-Balinese spiritual system, and a living social structure embedded in customary norms. While modernization has introduced significant changes in architecture and social structures, local communities have managed to adapt culturally without losing their traditional values. Community-based strategies have proven effective in preserving the harmony between cultural heritage and village development. The key outputs of this program include a landscape identity map, a social structure infographic, and a brief guide to customary spatial principles that may serve as a reference for village planning grounded in local wisdom. This study affirms the urgency of preserving collective identity and customary spatial systems as foundational to sustainable development in traditional Balinese villages.

Abstract

The construction industry plays a significant role. Construction projects carry a high level of risk, particularly in financial management and in balancing cash flow between revenue and expenditure. This study aims to analyze cash flow and evaluate the financial condition of the SDN 6 Kuta building construction project based on the schedule. The method used is descriptive quantitative, utilizing secondary data in the form of the Implementation Budget Plan, time schedule, and project progress reports. The results indicate that the project's Implementation Budget Plan Rp 1,975,413,914, with a payment system in installments and a 10% down payment. An analysis of the existing cash flow indicates a cash flow imbalance. In some periods, particularly until the middle of the project, cash outflows exceeded cash inflows, resulting in a deficit (overdraft), requiring the contractor to use personal funds to maintain the project. The implementation of alternative policies, such as increasing the down payment to 25% and adding additional funding sources, resulted in a more stable cash flow pattern, with cash receipts tending to exceed expenditures for most of the project period. Although the profit under the existing policy is higher at 12.58% compared to the alternative policy at 9.45%, the alternative policy is considered more optimal because it reduces the risk of overdrafts and improves the project's financial stability. Therefore, proper cash flow management through adjustments to payment systems and funding strategies significantly impacts the success of construction projects, not only in terms of profitability but also in terms of liquidity and project sustainability.

Abstract

Tourism has a very significant impact on economic development in a region. Tourism plays a role in accelerating the process of economic transformation in rural areas. Villagers who initially worked as farmers gradually learned to develop services to support tourism in a village. The momentum of tradition, culture and environmental exoticism can be packaged as village tourism products that attract visitors from outside the region. Efforts to increase the number of tourist villages to drive the village economy were also carried out in several villages in the Province of Bali. One of the village plans that will be developed as an ecotourism-based village is Besang Kangin Village, which is included in the administrative area of Semarapura Kaja Village. The previous year's PKM activities resulted in a jogging track master plan to attract visitors to Besang Kawan Village. As a supporting facility for tourism villages, the Besang Tourism Village Development Team plans to propose structuring traditional markets as one of the objects and places to market village community handicraft products. The problem faced in realizing this arrangement is the occurrence of floods which cause landslides in the market area, so a market arrangement design is needed that is safe from flooding and has a better appearance as a tourism object plan.

Abstract

This community service activity was carried out to support Sibetan Village, particularly Banjar Telaga, which is still facing limited access to clean water. The potential to meet clean water demand comes from the Dedari Spring, with a discharge of 1.5 liters/second, which is considered sufficient to serve 50 households at present and for the next 15 years. However, the spring is located below a cliff with an elevation difference of 107.78 meters from the reservoir point, thus requiring pumping technology for distribution. The methods used included field surveys, discharge measurements, water demand analysis, and the technical design of a Drinking Water Supply System (SPAM). The design process was carried out using hydraulic simulations with WaterCAD software to determine pump capacity, reservoir dimensions, and pipeline networks. Student involvement in mapping and analysis also provided academic value and practical experience in applying their knowledge. The results of the activity include a SPAM design equipped with a pump of 120-meter head, a discharge of 1 liter/second, a reservoir capacity of 30 m³, and a pipeline network of 1,686 meters. The network pressure meets the required standards, and the design is complemented with detailed drawings and a cost estimate of IDR 447,628,512.62. This design is expected to improve clean water access, support funding proposals, and align with the SDGs target of providing clean water and proper sanitation.

Abstract

In a project, effective management is crucial for organizing workflow and control to achieve the project's objectives. Project management involves continuous monitoring and evaluation of project performance to ensure that all parts of the project are on track. The aim of this study is to analyze the performance of the Warmadewa Educational Hospital Building Construction Project in terms of cost and time using the Earned Value method. The data used consists of primary data obtained from field observations and interviews, as well as secondary data from weekly reports, the Budget Plan (RAB), and the project schedule. The analysis shows that the project experienced delays from the first week up to the evaluation week. The Schedule Variance (SV) and Schedule Performance Index (SPI) analysis indicates that the project is progressing slower than planned. From the Estimate To Complete (ETC) and Estimate At Completion (EAC) analyses, the project is estimated to require an additional 719 days to complete. This represents a delay of 92 days from the initial planned duration of 627 days. The Cost Variance (CV) and Cost Performance Index (CPI) analysis indicate that the project costs are within the budget.
