<![CDATA[Implementation planning in project management is very important. Project implementation planning is a stage applied in project management by setting goals and objectives that must be achieved and determining the policies of all technical and administrative programs so that they can be implemented. Planning the implementation of development projects uses data collection methods with library and documentation techniques, the data obtained is in the form of secondary and primary data. The implementation method in the field uses conventional and mechanical methods to maximize work, one of which is pile cap work. Pile cap is a way to tie the foundation before a column is erected at the top. This pile cap aims to make the location of the column really at the center point of the foundation so as not to cause eccentricity that can cause additional load on the foundation. The pile cap carried out in the UPT Nyitdah Tabanan Hospital IGD Building Construction project uses four types of pile caps and the implementation method in the field uses mechanical methods. The scheduling results in writing this journal use the Precedence Diagram Method (PDM) method. The total duration based on the calculation is 45 days with a Bill Of Quantity (BOQ) including 10% VAT of Rp7,645,657,919.78.]]>

<![CDATA[One of the things that can damage the floor is gallon water bottles, milk bottles, shampoo bottles, detergent bottles, and other thick plastics made from organic compounds and made from high-density polyethylene (HDPE) plastic. We see an opportunity to utilize the substantial amount of plastic waste as an additional material produced by hot mixing in a flexible processing structure. lasto AC-WC mixture to determine the optimal amount of bitumen in the AC-WC mixture containing HDPE plastic additive and the AC-WC mixture containing HDPE plastic additive. An empirical approach was used in this study to add the VFB value of high density polyethylene (HDPE) plastic to the number of samples that needed to be tested to get the best bitumen content (KAO). 65 percent of the minimum requirements have been met by the VFB value. The stability value of Marshall Kao is also higher when HDPE plastic is used, with deviations of 0.50%, 1.00%, and 1.50%, respectively. The flow value meets the minimum requirement of 2 mm, despite the fact that the melting value (flow value) tends to decrease. In contrast, Kao increased the value of flexibility (MQ) by 1.00% for the 0.50n HDPE plastic mix variation, and the 1.50a variation saw a significant increase. The ideal amount of asphalt (KAO) is 5.70 percent. AC-coated asphalt concrete Gross Heavy WC, Ruston Asphalt Concrete Mix Design Result - Mounted Course uses high density polyethylene (HDPE) in the asphalt mixture at 5.70%, 0.50%, 1.00%, and 1.50% for each variation of HDPE plastic mix.]]>

<![CDATA[One of the waste materials which used as an additive for concrete mixtures is Coffee skin ash. Coffee skin ash is the result of burning coffee skin in the coffee bean grinding process. This waste is abundant in the Municipio Ermera (one of the big District in Timor-Leste), but its very limited to use. Municipio Ermera is a land and the center of coffee plantations in Timor-Leste. For this reason, an idea about use of wasted coffee skin ash is needed without causing damage to the environment. In this study, coffee skin ash used from Ermera area with a ratio of 0%, 5%, 10%, and 15% from cement weight. The purpose of this study to find how to compare the compressive strength of concrete between normal concrete and added coffee skin ash from Ermera. This method used in this study is experimental study and for each classification were made 5 specimens. The results of this research and analysis it can be concluded the compressive strength value of concrete using coffee skin ash as a partial replacement for cement composition with normal concrete has a significant comparison. Where it was found that concrete using coffee skin ash with composition of 5%, 10%, and 15% had a higher compressive strength value to concrete without coffee skin ash. The comparison of the increase in compressive strength that occurs is around 16% to 19,6%.]]>

<![CDATA[The development of development in urban areas will also have an impact on the land cover area. Efforts that can be made to determine urban development are by looking at land cover information through land cover maps. Land cover data can provide information in studying climate change and understanding the relationship between human activities and climate change. The method used is descriptive with interpretation of Landsat 8 imagery, using a Geographic Information System (GIS). Normalized Diffrence Vegetation Index (NDVI) is a calculation on an image that is used to determine the level of greenery as the initial division of vegetation and land cover areas. Klungkung Regency in the last five years continues to experience changes. The area of paddy fields in Klungkung Regency in the past five years tends to decrease. In 2013 the area of paddy fields was 3,843 Ha, reduced to 3,779 Ha in 2017. Based on the results of Landsat 8 satellite imagery, from 2016 to 2021 there was a decrease in the area of vegetation density by 35.11 km2 or 11.39% while the area of residential land cover increased by 29.98 km2 or 9.73%.]]>

<![CDATA[The floriculture garden plays an important role in the preservation of plants, especially ornamental plants and also plays a role in overcoming the problem of global warming and contributes to the provision of urban green open spaces. The unwise exploitation of the existing biodiversity is one of the reasons for increasing greenhouse gas emissions in Indonesia. In addition, there is also a phenomenon of reduced open space in urban areas due to land conversion due to the high population growth in Indonesia. This is in accordance with the current condition of the city of Denpasar which has become an urban city with the most populous population in the province of Bali. This phenomenon makes the area of Denpasar City Public green open space less than the ideal standard. On the other hand, there are still many types of ornamental plants in Indonesia that have not been conserved. Thus, it is necessary to procure a Floriculture Park in Denpasar City to overcome the problem of the number of ornamental plants that have not been conserved, global warming that occurs, and the reduction of green open space in urban areas. This design also aims as a recreational and educational facility. The basic concepts used are recreational, conservation and educational. While the chosen design theme is a biomorphic architectural theme with sustainable forms, structures and materials. The design method used is data collection techniques in the form of library research, observation and comparative studies, as well as data processing methods, namely analysis, synthesis and transformation methods. The results of the design of the Floriculture Park in Denpasar City are explained into three principles of biomorphic architecture. The first principle is the principle of form, namely the form of mass based on ecology and metaphor of natural forms. The second principle is the principle of structure and material, its application is the use of structures with organic shapes, while in terms of materials the application is by selecting natural (local) materials and materials that support a curvilinear shape. The third principle is the principle of sustainability, the application of which is to maximize the use of natural energy into buildings.]]>

<![CDATA[Architectural development is a manifestation of human desire for a better direction. If observed, its development can resutl in changes to the architectural from itself. This change is a product of adaptation or response to developments in culture, economy, environtmeent, technology and architectural styles. One example that can be observed is the change in pamesuan architecture int he traditional village of Badung Regency. This study aims to identify and analyze the typology of change in the form of pamesuan architecture in Bongkasa Pertiwi Village, Badung Regency. The research method used in this study is a qualitative method, with data analysis in the form of descriptive originating from empirical information. The analysis process is based on the form and general function of the pamesuan based on theoretical studies as a grand concept. The results of identification and grouping, there are four types of architectural forms of pamesuan in Bongkasa Pertiwi Village. Each type has several differences such as the type, structure, material, appearance concept and dimensions. The results of the grouping are then analyzed based on theoretical studies to find change in from that have occured. Changes in form were found in the form of addition, elimination and movement of shapes and elements such as the addition of lighting elements, dimensions of the entrance. elimination of elements forming the tri angga concept, namely the roof (head). Movement of the form of circulation access in the form of a ramp. Changes are certainly good, but still pay attention to the core elements and characteristics of the pamesuan architecture in each region. This research is expected to provide benefits in exploring local wisdom in traditional Balinese architecture, especially pamesuan architecture.]]>

<![CDATA[Economic activity that occurs in a region will affect how the development of development in the region. There are points of economic growth centers that will have an impact on the surrounding area. The influence in question can be in the form of the surrounding area also developing or even being left behind. There are various types of economic activity, one of which is economic activity in the tourism sector. This research was conducted by choosing Badung Regency in Bali Province as a case study because Badung has very rapid tourism activities compared to other districts in Bali. Tourism activities in Badung are only centered on a few points which results in inequality and uneven development in the Badung area. This study aims to determine the influence of tourism development in Badung, to find out how much influence the trickling down theory and polarization effect have in Badung, and to find out the efforts that can be taken to achieve equitable economic development in Badung. The research data was obtained by conducting a literature study and the research was carried out using a qualitative approach which would later produce descriptive data. The final results of the study show that tourism activities in Badung are a vital sector on which economic development and development in Badung depend; trickling down and polarization effects occur in Badung with different regional scales; as well as the need for the development of other tourism sectors in the suburbs of Badung Regency which is supported by government policies.]]>
