Abstract

To achieve the level of infrastructure performance as a middle-income country by 2025, as well as to catch up with the backwardness of infrastructure, specifically for toll road projects, the government targets that by 2021 Indonesia will have 5200 km of toll roads. Hence, there is a significant increase of 3000 km. The government, especially in the development of toll road infrastructure, gives a more significant portion to the purely private sector, BUMN, and Public Private Partnership - Government Business Entity Cooperation. Risk analysis is carried out by structuring risk using the RBS (Risk Breakdown Structure) method and multiplying the impact value and frequency to get the risk level value for each risk factor. The results of the analysis obtained from RBS are further analyzed based on the practical experience of project implementers to determine their actions in overcoming risks, then analyzed and discussed again using a table comparing the amount of risk, comparison of the level of importance of risk (importance level) and the level of risk based on the payment system. The results obtained from this study are the types of risk and the level of risk at each stage of the project.

Abstract

Building structure planning must be distinct from foundation structure planning. The foundation plays an important role in transferring building loads to the ground. The Warmadewa Gianyar Hospital building consists of 5 floors with a building area of 8323. 471 m2 on a granular soil location where there are three layers of soil types, namely sandy silt soil, silty sand, and sand mixed with rock grains. The Borepile foundation is installed at a depth of 12 m with an N SPT value of 60. This building carries dead loads, live loads, rain loads, wind loads, and earthquake loads. This building will use a bore pile foundation by modeling bore pile piles in GEO5 software to obtain safety factor values and installed reinforcement. Based on the analysis results, the pile diameter used is 450 mm and has a length of 12 m. The analysis obtained the carrying capacity with a safety factor of 2.1> 2 and a maximum settlement of 4.77 mm.

Abstract

Fondasi merupakan bagian dari bangunan yang meneruskan beban yang ditopang ke dalam tanah. Bangunan bertingkat tinggi biasanya dibangun menggunakan fondasi dalam seperti tiang pancang, tetapi ada juga bangunan tinggi yang dibangun menggunakan fondasi dangkal seperti fondasi rakit. Fondasi rakit berfungsi menyebarkan beban dari struktur ke tanah di bawahnya yang terdiri dari pelat tunggal yang meluas. Pada Gedung Ditreskrimsus Polda Bali yang memiliki area basement yang difungsikan sebagai lahan parkir, terkait dengan hal tersebut dilakukan pemilihan penggunaan pondasi rakit meskipun nilai SPT > 10 dan kedalaman dibawah 3.5 m adalah tanah lempung berpasir yang padat. Analisis yang digunakan yaitu dengan analisa tegangan yang terjadi dari total gaya aksial yang terjadi pada setiap kolom dibagi total luas rencana fondasi rakit, dengan solusi tersebut diharapkan bangunan menjadi lebih stabil terhadap penurunan segera. Berdasarkan hasil analisa diperoleh dimensi pondasi rakit 23.65 m x 48.65 m, tebal pelat 350 mm dan tebal pada bagian kritis bawah kolom yaitu 900 mm. Pondasi rakit yang direncanakan sudah aman dari geser pons. Tegangan dasar pondasi maksimum sebesar 82 kN/m2 masih lebih kecil dari daya dukung tanah yaitu sebesar 335.09 kN/m2. Penurunan segera yang terjadi sebesar 13.63 mm lebih kecil dari batas penurunan maksimum yaitu sebesar 65 mm.

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

Landslides on slopes are the second most frequent natural disaster after floods which cause many losses if they occur. Therefore, it is necessary to predict slope failure to prevent it. One of them is the slope in Trunyan village, Bangli sub-district, Bali. In predicting slope vulnerability in this area, the Linear Discriminant Analysis method was used from 40 slope points using 2 variables, which is the existing condition of the slope and the slope of the slope, only 40.7 percent of the total variables that influence the slope with the results of the analysis there were 28 slope points from the 40 slope points. There are indications of landslides or 70 percent, the relatively small Wilks Lambda is 0.593 and the significance is less than 0.01, making the results of this research suitable for use. This analysis shows that existing strengthening and slope slope have a significant influence on slope stability and can be used as indicators in evaluating the risk of slope collapse.

Abstract

Polsek was a police station in the district that provides police services to the community. There are four types of Polsek, namely A, B, C, and D. Polsek in the Bali Area are 58 with types B and C. Polsek is expected to have adequate supporting infrastructure such as Integrated Police Service Center rooms, facilities for the disabled, children's playgrounds, breastfeeding rooms, detention cells, and parking, open spaces. However, the land area is only sometimes adequate. The analysis used interview methods, observation, literature studies, and SWOT analysis. The results show that Polsek's need for land Type B is 631.54 m2, and Type C is 377.14 m2. The SWOT analysis was in the strength and threat quadrant, so a policy is needed to evenly distribute the development of each Polsek type B and C, starting from land acquisition by the main tasks and functions of the police in serving the community.

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 construction project of the store and restaurant in Semer Street, Kerobokan, Badung has changes in some of the structural elements which previously used steel structure to concrete structure. The author chooses to use concrete for the main and sub-structure, while the steel was maintained for the upper structure. The purpose of the analysis are can be able to design the structure of the store and restaurant building that has a strenght plan greater than or equal magnitude of the ultimate force that occurs and also to find out the comparison of story drift between the exsisting and planned building. Analytical method is using study literature on it’s planning by collecting data that related to the plan such as architectural data and soil data. Based on the result of the structural analysis it can be concluded that the control of structural elements has met the standard and on both model where in the story drift have a reduction in deflection due to the material used. The greatest reduction of story drift for Y direction is 61% on the 4th floor and for X direction is 36% on the 1st floor.

Abstract

Penelitian ini dilatarbelakangi oleh peningkatan signifikan pembangunan sektor pariwisata di Bali, dengan jumlah kamar hotel nonbintang yang meningkat dari 32.810 kamar pada tahun 2021 menjadi 36.886 kamar pada tahun 2023. Keterbatasan lahan di Bali Selatan mendorong investor beralih ke pembangunan hotel dan vila di wilayah perbukitan Bali Tengah, yang menuntut analisis stabilitas lereng menggunakan dinding penahan tanah (DPT) tipe gravitasi. Tujuan penelitian ini adalah membandingkan efektivitas safety factor dan nilai ekonomis antara DPT gravitasi menerus dengan DPT terasering pada berbagai variasi tinggi dan sudut lereng. Metode penelitian menggunakan analisis numerik dengan Finite Element Method (FEM) melalui aplikasi Plaxis untuk mengevaluasi faktor keamanan pada empat model DPT gravitasi dengan variasi jumlah terasering, tinggi terasering, dan sudut lereng 45° dan 60° pada lereng setinggi 10 meter. Evaluasi ekonomis dilakukan melalui perbandingan luas penampang DPT, volume galian, dan timbunan. Hasil penelitian menunjukkan bahwa faktor keamanan pada DPT menerus lebih tinggi 5-15% dibandingkan DPT terasering, namun memerlukan luas penampang yang lebih besar hingga 145% dan volume galian yang lebih besar 162%-225%. Implikasi penelitian ini menunjukkan bahwa DPT terasering lebih efisien secara ekonomis meskipun memiliki safety factor yang sedikit lebih rendah, sehingga dapat menjadi alternatif yang lebih praktis untuk penanganan stabilitas lereng pada ketinggian sekitar 10 meter di wilayah perbukitan Bali.
