UPN “Veteran” Yogyakarta’s Land Asset Area Planning in Semanu Gunung Kidul, Yogyakarta

Land is an asset in today’s era of development. A patch of land’s management must be planned so that its utilization can be done proportionally and professionally. The Special Region of Yogyakarta, namely Gunung Kidul Regency, has yet to have a reliable base map with high accuracy for each patch of land within its area, which results in the hampering of land use due to the lack of spatial information available. The lack of clear status and spatial information is felt by UPN “Veteran” Yogyakarta that has several patches of land in Gunung Kidul Regency, namely Kuwon Kidul, Pacarejo, Semanu, Gunung Kidul Regency. This research will create a base map scaled to 1:500 accompanied with information about height differences of said area and a recommended planning area considering three different aspects: geology, environment, and agriculture. The creation of a topographic map is useful for construction planning that will be conducted in the area. During this research, the topographic measurement and data processing were done in 11 days on field. The topographic measurement and data processing were conducted through five stages: initial survey, GNSS measurement, detail measurement, and data processing using software to produce a topographic map. The map result and measurement on field using Total Station showed that UPN “Veteran” Yogyakarta does not have a level surface and has good data density.

A simulation-based decision support tool for integrating site layout and construction planning of tunneling projects

Purpose Integrating construction and site layout planning in mechanized tunnel infrastructure projects is essential due to the mutual impacts of construction planning and site layout decisions. Simulation can incorporate site layout planning and construction planning of tunneling projects in a unified environment. However, simulation adoption by industry practitioners has remained relatively limited due to the special skills required for building and using simulation models. Therefore, this paper aims to create a simple-to-use simulation tool that supports site layout and construction operation planning of tunneling projects. This tool intends to promote the simulation application in site layout planning. Design/methodology/approach The current paper proposes simulation as a decision support tool (DST) to provide an integrated environment for modeling tunnel construction operations, site layout and capturing the mutual impacts. A special purpose simulation (SPS) tool was customized and developed for typical mechanized tunneling projects, by tunnel boring machines, to facilitate building the model and allow access to users with limited simulation knowledge. Findings The results show that the developed SPS tool is of great assistance to construction industry practitioners to analyze a variety of site layout and construction plan scenarios and make informed decisions based on its comprehensive and intuitive outputs. Originality/value The main contribution of this research is to promote simulation application in site layout planning of tunneling projects through the development of a simple-to-use tool, which has sufficient details for site layout planning and constraints. The developed DST enables planners to make decisions simultaneously on the site layout, other construction planning variables and identify the most efficient plan.

The Journey for Digital Well Delivery Technology Adoption: The How and Why

As part of the industry 4.0 revolution, digital technologies are forever changing the way we do things. native cloud applications are able to adapt to specific processes and requirements, particularly those related to well construction planning driven by an automated collaborative solution. The operator of the future will use its engineers mainly for engineering analysis and social interactions, while the system will take over tasks such as orchestration, data mining, and experience management. Based on the definition of a new way of working and the application of new workflows, a thorough trial process was required to evaluate the solution usability and to define the minimum viable product requirements to be developed within a strategic partnership prior to rolling out the technology. The requirement was to enable globally dispersed teams, even across company borders, collaborating through automatically orchestrated processes, supported by knowledge and experience management systems in the background, to deliver a digital drilling program and ultimately accelerate the field development program. The operator decided to prove the concept through a series of pilots within a well-educated well planning team. Major assumptions to the business case were tested while planning actual drilling operations with the purpose to de-risk the value proposition. All different tested elements are captured by the users and the gaps to the final solution are ranked for joint development. The back-end interoperability of the solution supports a fully connected model, where data from subsurface systems can directly feed the well construction planning platform. The automated updates in the end-to-end workflow would ultimately simplify the way drilling engineers work, but also upscale the nature of their work by including many new elements as part of the routing analysis. Supported by the cloud computer power and flexibility, remote working is seamlessly enabled to removing the classic silos and digitally promote the collaboration. Standardization across the whole organization by corporate managed settings reduces iterative control processes. Furthermore, management of change is a key aspect to consider alongside the technical elements. The result of the extended trial confirmed that achieving the minimum viable product requirements of the operators was well within reach and confirmed the operator's value case to a large extent. In this paper we will describe the extended trial process, objectives, and associated workflows, in addition to the collaborative team nominated by both partners. The scope was user centric to assist with competency development and technology adoption. Parallel to confirming the minimum viable product, the extended pilot resulted in a prioritized list of co-developments leading to the full implementation of the operator's vision of a fully integrated well planning workflow.

Meningkatkan Kualitas Pelayanan Jalan Raya Plandaan – Boro Tulungagung Menggunakan Perkerasan Kombinasi Geotextile

Roads as a means of transportation have an essential role in supporting human activities. One of the developments in road construction is the application of geotextiles in road combination pavements. Geotextile itself is often found in construction planning, especially in soil stabilization. The plandaan – boro Tulungagung road section is indicated by the type of silt as deep as 1.2 meters so that improvements are needed to support the quality of road construction. The purpose of this research is to plan road pavement with geotextiles on the Plandaan to boro roads. The geotextile used is a woven geogrid geotextile. The method used in planning is the Bina marga method of the 2017 Road Pavement Design Manual. The data used include technical data, traffic data, and California Bearing Ratio (CBR). The planning includes traffic design, pavement thickness calculations, and volume calculations. The planning results will be HMA – WC pavement covering an area of 4,200 m, with K225 concrete pavement covering an area of 8,400 m. Class Bﬞ Aggregate Pavement covering an area of 10,500 m using a geotextile layer requires 51,000 m² so that these results can be used as a reference in the repair or improvement of the Plandaan - boro Tulungagung road.

Modeling of scenarios for the underground construction planning based on the foresight and cognitive modeling methodologies

The modeling of scenarios for the underground construction planning is based on the mathematical support of fore sight methodology aimed at the creation of alternative scenarios and the cognitive modeling to build scenarios for the development of a desired future and ways of their implementation. We propose to use these methodologies together: the results obtained at the stage of the foresight methodology should be used as initial data for the cognitive modeling. Using the foresight process at the first stage of modeling allows us, with the help of expert assessment procedures, to identify critical technologies and to construct the alternatives of scenarios with quantitative characteristics. For the justified implementation of a particular scenario, the cognitive modeling allows one to build causal relationships with the consideration of a large number of interconnections and interdependences. The developed strategy is applied to the study of underground construction objects in order to select reasonable scenarios for their future development.

Application of Digital Well Construction Planning Tool During Well Conceptualization Phase

Digital well construction tools are becoming more widely considered today for well design planning, enabling automated engineering and simultaneous team collaboration under a single solution. This paper shows the results of using a digital well construction planning solution during a project’s conceptual planning stage. This method shortens the time needed to estimate the well times and risk profile for a drilling campaign by applying smart engines to quickly and accurately perform critical offset analysis for defined well types that is required for project sanction. With this solution, the Offset Well Analysis (OWA) process is done automatically based on the location of the planned well, trajectory and well architecture. Various information and reports (both subsurface and surface data) from neighboring wells is stored in cloud solutions, enabling ease of access and data reliability for both large or smaller scale data storage. The software selects the most relevant offset wells, displays the risk analysis and generates the stick chart. For a conceptual design, the risk levels can be manually set higher due to potential unknowns in surface and subsurface risks which can later be refined. Quick validation of the well design allows the engineer to design a conceptual drilling campaign quickly and more efficiently. The solution minimizes the time to perform probabilistic time and risk estimations. It reduces the risk of biased decision making due to manual input and design. This allows for better-informed decisions on project feasibility, alignment of stakeholders, increased design reliability as well as reducing the amount of time and resources invested in OWA. The work presented here is aimed at sharing the experience of applying a digital well construction planning solution specifically on the conceptual project stage and discuss the value it adds to the well design process.
