2024-01-12T05:46:03+07:00

Water scarcity is increasingly becoming a significant challenge in arid and semi-arid lands. In these areas, small dams and reservoirs are important in providing water resources, supporting agricultural activities, and contributing to sustainable and resilient rural communities as they require an affordable investment. However, their frequent failures pose significant challenges to sustainable water management and agricultural development in these regions. This review study was developed based on the review of many international standards and guidelines from published studies in scientific journals in addition to information from practitioners. We examined the significance and causes of the failure of small dams and reservoirs; and discussed design criteria and considerations involved in their construction. The outcomes of this study offer valuable insights into the significance of small-scale irrigation dams and shed light on the multifaceted causes of their failure. A holistic approach to address the challenges identified are approach is required. Integrating engineering solutions such as improving design, and regular maintenance, with sustainable land management are crucial for optimising the small dams and ensuring that they adequately serve the needs of the community. The causes of failure were found to be multifaceted encompassing factors such as poor construction and maintenance practices and inadequate design considerations. Finally, this review highlighted the key elements in assessing structural conditions critical to the functionality and sustainability of small dams and reservoirs.

Infrastructure development in Kenderan Village, Tegallalang sub-district, Gianyar regency

2024-01-12T05:46:04+07:00

Gianyar Regency has many villages that can be relied upon as tourist destinations due to their cultural and natural potential. Kenderan Village has a natural atmosphere with vast stretches of rice fields and hills, which are the main attractions of this village. Various potentials can be developed through ecotourism concepts as tourist attractions. The development of tourist village infrastructure involves the arrangement of the area and environment to maintain its natural state, as well as the optimal development of other supporting tourist facilities that have not been utilized. The aim of this research is to identify the potentials in Kenderan Village (cultural, natural, and village potentials) and to determine the necessary infrastructure for the development of Kenderan Village as a tourist village. This study uses observation, interviews, and documentation as research techniques, employing the SWOT approach. The results of this research show that there are various tourism potentials that can be developed into various attractions and activities, which can be categorized into three types: natural potentials (rice fields, plantations, and natural beauty), cultural potentials (archaeological sites, Beji Telaga Waja, and Pura Griya Sakti Manuaba), and village potentials (Puri Agung Kenderan and traditional settlements). The development of tourism potentials in Kenderan Village is expected to provide optimal benefits for the local community, entrepreneurs, and the government in a sustainable manner, while contributing to environmental preservation.

Characteristics of Balinese architectural flats in Denpasar city

2024-01-12T05:46:04+07:00

The construction of flats can be a solution to the increasing need for houses in the Province of Bali and the depleting land area of residential areas. The existence of demands for flats by prioritizing the architectural requirements of buildings according to the Regional Regulation of the Province of Bali Number 5 of 2005 is a unique thing to study. The aim of the research is to find the factors that influence the characteristics of flats with Balinese architecture and to plan a design model for flats in Bali based on the concept of Balinese architecture. This study uses a combination research method model which combines quantitative and qualitative research methods sequentially. In the first stage it was carried out using quantitative research methods and in the second stage used qualitative methods. Sampling using non-probability random sampling, with the sampling convention sampling technique, where the sample selection is free with a sample of 200 respondents. The data analysis technique in this study was univariate analysis by presenting tables, pictures and graphs. The results of the study show that the factors influencing the characteristics of flats with Balinese architecture are the principles of spatial planning with the selection of locations in Denpasar city, the principles of building layout with a 3-storey apartment building height and the selection of building facades in Balinese architectural style, the principles of utilities and facilities with the presence of green open spaces. , elevator facilities, traditional and cultural facilities, vehicle parking facilities centered in one place, merchant facilities, health and education that are easily accessible, as well as an integrated and organized waste treatment system, as well as the principles of Balinese architecture, namely based on Tri Hita Karana and Hulu Teben concept. The design model for flats is designed with a type 36 residential type which facilitates the majority of families with 1-2 children.

Analysis of penel drop-off on shear slip at flat slab in the animal hospital education building of the Faculty of Veterinary Medicine (RSHP-FKH), Udayana University

2024-01-12T05:46:04+07:00

The Animal Hospital Education of the Faculty of Veterinary Medicine (RSHP-FKH) at Udayana University is located on Sesetan Main Road, Markisa Alley, No. 6, South Denpasar District, Denpasar, Bali. The building structure is planned with a modified flat slab design incorporating drop panels around the column areas. The purpose of this modification is to provide flexibility in spatial arrangement, facilitate the installation of mechanical and electrical systems, and indirectly meet the height requirements specified by the local regulations in Bali. The structural analysis of the Animal Hospital Education building at RSHP-FKH, Udayana University was conducted using the ETABS v.18 software, following the guidelines of the Indonesian National Standard (SNI). The analysis focused on the effect of drop panels on shear slip in the flat slab. The analysis aimed to determine the magnitude of deflection and its corresponding locations in the structure. The results of the analysis provide relevant information regarding the strength and stability of the building structure, ensuring that the RSHP-FKH building at Udayana University meets the established standards.

Deflection of flat slab-drop panel in the G2 building at Warmadewa University

2024-01-12T05:46:04+07:00

To conserve building height, flat slabs are concrete structures that do not employ beams as weight transfer to columns. The flat slab system structure is prone to shear collapse due to the lack of beams. A column head is made to forward the load from the plate to the column so that the shear value in the building is not too high. This is done by expansion at the end of the column or by thickening around the critical circumference of the column and plate meeting. The Warmadewa University G2 Building Planning Analysis is carried out during the planning stage, using a flat slab-drop panel structural system as one of the optional structural systems that can be used to obtain a building height that is in accordance with Bali Provincial Regulation Number 16 of 2009 concerning the regional spatial plan of the Province of Bali. Terompong street No. 24, Sumerta Kelod, East Denpasar sub-district, Denpasar City, Bali, is where the Warmadewa University G2 building will be built. According to the soil data, the building is constructed on a medium soil site class with a building structure risk level IV. The Warmadewa University G2 Building structure was studied using etabs v.18 software in accordance with SNI 2847-2019 requirements for structural concrete for building buildings and loading in accordance with SNI 1727-2020 criteria. The biggest deflection value occurs in the middle lane due to the load from the function room, as determined by the study for the dimensions of the 350mm thick drop panel and 250mm thick slab utilizing a column size of 600 x 600 mm with a span of 8000mm. The inner drop panel experiences the highest lateral loads due to shear failure.
