Abstract

As one of the largest archipelagic nations, Indonesia faces significant coastal erosion challenges, particularly in Gianyar Regency, Bali, where coastline change rates have reached -11.12 m/year. To combat this issue, the Indonesian government has implemented revetment structures along the coastline, notably at Lebih Beach. This research systematically assesses the current performance of a coastal revetment structure on Lebih Beach, focusing on its ability to withstand modern wave conditions and prevent wave overtopping. The objective is to evaluate the structure’s physical integrity and functionality, especially as wave overtopping has impacted nearby communities and damaged infrastructure. The methodological framework incorporates detailed field surveys to document structural conditions and detect signs of erosion, material degradation, or damage. Topographic and bathymetric data are used to model the coastal and seabed profile, which is essential for simulating wave behavior. Wind, tide, and wave data from CMS-Wave in SMS 10.1 software provide insights into wave height, direction, and energy, helping predict wave impacts on each segment of the coastline. The research area is divided into six segments along the Lebih Beach coastline. Initial evaluations showed that segments 1 through 4 require further analysis due to evident vulnerabilities to wave forces. The reexamination compares the peak elevation of these segments, specifically their ability to withstand wave action at the established elevation of +5.00 m. This comparison allows for an accurate assessment of the structure’s resilience under current environmental pressures and guides recommendations for maintenance or reinforcement where needed. The evaluation results in segments 1, 2, 3, and 4 showed that the revetment still undergoes overtopping. Continuous monitoring and evaluation of coastal protection structures is needed to ensure the integrity of coastal communities and infrastructure in the face of ongoing environmental changes.

Abstract

Pertumbuhan populasi menjadi elemen penting dalam meningkatnya limbah rumah tangga dari dapur, yang dapat menyebabkan pencemaran lingkungan karena bertambahnya aktivitas dan konsumsi. Penelitian ini bertujuan untuk menganalisis desain dan alur pengolahan limbah dapur permukiman Desa Baha, dengan perhatian khusus pada Banjar Gegaran, yang dipilih berdasarkan jumlah kepala keluarga terbanyak. Pendekatan yang dipakai adalah deskriptif kuantitatif, dengan mempelajari pertumbuhan penduduk di masing-masing permukiman serta volume limbah domestik yang dihasilkan. Proyeksi angka pertumbuhan populasi untuk tahun 2025 hingga 2034 menggunakan metode Regresi linear menunjukkan adanya peningkatan, berdasarkan rumus Y = 29,20 + 0,8X, serta menunjukkan hubungan positif yang signifikan (r2 = 0,94) antara jumlah penduduk dan waktu. Diperkirakan pada tahun 2034, populasi maksimum adalah sebanyak 39 jiwa. Volume limbah domestik dari dapur yang dihasilkan oleh tiap permukiman di Desa Baha diperkirakan bisa mencapai 686,4 liter per hari untuk setiap rumah tangga. Rancangan dan proses pengolahan limbah disusun dengan mempertimbangkan volume maksimum air limbah yang diproduksi dikalikan dengan faktor koefisiennya, sehingga diperoleh desain instalasi pengolahan air limbah (IPAL) dengan kapasitas 1 m³ yang direncanakan untuk mengelola limbah dapur hingga tahun 2034, dengan proyeksi limbah harian sebanyak 0,78 m³ per rumah tangga. Kapasitas ini memberikan cadangan sekitar 22% untuk menanggulangi kemungkinan perubahan volume limbah.

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

One of the innovations that has received attention is Building Information Modeling (BIM). The software that applies the BIM concept is Autodesk Revit. This study compares the Cost Budget Plan (RAB) obtained through the BIM method, and the RAB calculated by conventional methods in the Denpasar Undiksha Campus Lecture Building Construction Project, to identify a more efficient method used in project cost estimation. The method used in this study is to collect project data in the form of structural work drawings, unit price analysis, and RAB, which is used as a reference for modeling with Autodesk Revit. The RAB calculated using the BIM method modeled on Autodesk Revit was obtained lower at IDR 3,003,134,274.71. while RAB was obtained from contract documents of IDR 3,425,386,712.44. The comparison between Autodesk Revit's RAB and the contract document RAB shows a difference of IDR 422,252,437.73 with an efficiency value of 12.33%. The Cost Budget Plan (RAB) generated through modeling using Autodesk Revit shows lower and more efficient values. This shows that the application of BIM methods in project cost planning can provide more accurate and optimal results

Abstract

The construction implementation system in the Mandala Mathika Subak Museum Revitalization project uses the cast in situ or conventional method including floor slab work. The implementation of floor slab work with the cast in situ method requires a long processing time and a lot of labor and costs incurred. In the construction of the building, the selection of work methods is very influential on the implementation time and cost. The selection of the right method will make the development efficient. One of them is the use of precast concrete such as half slab. In this study will compare conventional methods and half slab methods from the aspects of implementation time and cost, which is more profitable. The results of the comparative analysis of execution time and costs from the calculation of cast-in-situ and half-slab plates in the Revitalization Project of the Mandala Mathika Subak Museum show that using the half-slab method saves 33% in costs compared to the cast-in-situ method, with a cost difference of Rp. 552,730,037, and can accelerate the execution time of 43% or 19 days.

Abstract

Construction project implementation planning is an important stage that aims to optimize time, cost, and quality of work. In the construction project of the Badung Regency KPU Office Building, implementation planning is very crucial considering the location of the project which is in a densely populated area, so that an appropriate and efficient implementation method is needed. The problems faced are how to prepare an implementation schedule, calculate resource requirements, and plan costs systematically so that the project can run according to plan. This study uses the Precedence Diagram Method (PDM) to prepare the project schedule and Microsoft Project as a visualization tool. In addition, an analysis of human resource needs, materials, and tools was carried out as well as the preparation of the Implementation Cost Plan (RBP) and Budget Plan (RAB). The results of the study show that implementation planning using the PDM method produces a structured and efficient project schedule. The total cost obtained from the RBP analysis results is IDR 4,159,270,327.34, while the RAB reaches IDR 4,623,397,141.26, with a cost difference of IDR 464,126,813.93. This research is expected to be a reference for planning the implementation of similar building construction projects, especially in the context of using the PDM method.

Abstract

Aims: This research will provide an overview of the comparative analysis of watershed characteristics in Bali which are differentiated from watersheds flowing to the north, and watersheds flowing to the south of Bali Province. The aim is to determine the characteristics of each, and proper sustainable management for each watershed. Methodology and Results: This is a descriptive, quantitative research that analyzes and compares the characteristics of the Saba watershed and Unda watershed, where the characteristics analyzed are morphometric and hydrological.  From the analysis, it was observed that the Unda watershed, which has a flow direction to the south of the island of Bali, and the Saba watershed, flowing to the north of the island of Bali, possess several differences and similarities. The similarities include rainfall patterns, high temperatures, and the comparison values between Qmax and Qmin is significant. Meanwhile, the differences include the Saba watershed slope being steeper than the Unda watershed, and the Saba has young geomorphic features, while the Unda watershed possesses advanced geomorphic features. Conclusion, significance, and impact of study: Differences in watershed characteristics lead to differences in the management carried out. Furthermore, in terms of hydrology, where there are lesser differences, the sustainable management of the Saba and Unda Watershed also require conservation in form of a reservoir (weir or dam). This is to enable the storage of water in the rainy period for the dry season.

Abstract

Kuwum Village, in Mengwi District, Badung Regency, Bali, is about 29 km north of Denpasar. Here, raising Bali Kereman cattle supplements farmers' income from farming and other jobs. Despite the potential profitability from meat, offspring, manure, and labor, the Nandini cattle group faces challenges. These include insufficient capital, inadequate feed, poor cattle maintenance, inefficient manure processing, and underdeveloped manure sales channels, hindering income maximization. The primary issue is low management capability in cattle maintenance. Effective cattle raising requires an ideal stable location, at least 10 meters from houses, accessible by vehicle, and near agricultural land, allowing sunlight. Quality seed selection, stable maintenance, and adequate feeding are essential. To address these challenges, methods such as presentations and demonstration plots for forage feeding and cage spraying are used. These activities aim to improve farmers' knowledge and practices, increasing cattle weight and farmers' income, ultimately achieving better welfare. Community Service activities have enhanced understanding and demonstrated proper maintenance, feeding, and cage spraying in the Nandini cattle group
