“…Dalam Permen PUPR Nomor 8 tahun 2023 tersebut diatur pembentuk harga satuan pekerjaan bahwa Perkiraan Biaya Pekerjaan salah satunya melalui mekanisme Analisis Harga Satuan Pekerjaan. Lebih jauh permen mengatur bahwa pembentuk harga satuan pekerjaan didalamnya harus terdapat beberapa komponen seperti: tenaga kerja, bahan, dan peralatan (Tupan & Suryanto PLN Wilayah Maluku dan Maluku Utara, 2019) (Sarasanty, 2023) (Liu et al, 2014) Dalam laporan RTT Perluasan Terminal Bandara Internasional Lombok, penganggaran menggunakan metode langsung dengan perhitungan komponen-komponen pembentuknya dengan nilai koefisien, ini mematuhi terkait aturan Permen Nomor 8 tahun 2023 tersebut. Berikut salah satu analisis harga satuan dari pekerjaan Perluasan Terminal Bandara Internasional Lombok untuk pekerjaan 1 m2 pekerjaan Cat Exterior (luar bangunan) (Kontrak Pengadaan Barang Dan/Atau Jasa 2020, 2020) (Ramadhan, 2021).…”

This study aims to analyze the budgeting process for the Expansion of Zainuddin Abdul Madjid Lombok International Airport Terminal at PT. Angkasa Pura 1 (Persero). The output of the final planning report will be analyzed using a comparative description method of aspects of company budgeting through the perspective of capital budgeting or investment, which is more project management or engineering system than investment in securities or others. The budgeting of Lombok International Airport Terminal Expansion Work from the search results has fulfilled some aspects of good corporate budgeting, although some strategic predictions missed expectations. The company's own capital budgeting in application and practicality there are several weaknesses in predicting future returns from the value of investments issued due to lack of integration with the company's strategic objectives or to top-level regulations that must be met, especially in the acquisition of asset values or fixed assets with significant value. With this paper, it is hoped that it can generate awareness of the importance of evaluating capital budgeting before the budget is issued to be tested for implementation from a value and time perspective.

“…In recent years, hardware and software have converged and are dependent on one another such that the two are no longer mutually exclusive. In addition to classifying BoMs based on their structure and functionality (Zhou et al 2018; Liu, Lai, and Shen 2014), the authors introduce a classification category based on their component type. BoMs can contain sensitive information which may not be public and require restricted access, so the authors also introduce another classification category to accommodate this criterion based on a BoM's availability.…”

The evolution of cyber‐physical infrastructure has made its security more challenging. The last few years have witnessed a convergence of hardware and software segments in various domains, including operational technology (OT) which is responsible for carrying out critical tasks such as monitoring and controlling power grids, nuclear plants, transportation, and emergency services. Both hardware and software encapsulate numerous open source and proprietary subcomponents, making it crucial for end‐users to understand the composition of the products they are using. For example, wind turbines incorporate thousands of lines of code (software) used for the turbine's design, planning, operation, and analytics in addition to the numerous hardware subcomponents that construct it. Due to the highly complex nature of software and hardware, knowledge of the components and subcomponents is required to mitigate cyber vulnerabilities and to defend against cyberattacks. There has also been a transformation from a traditional linear supply chain into a global, dynamic, diverse, and interconnected system. The digitization of the supply chain makes it easier to find and exploit vulnerabilities. Critical infrastructures (e.g., power grids, oil, natural gas, water, and wastewater) rely on OT to function, and if the OT is compromised, equipment damage and potential interruption of services could result. A significant security measure to protect OT systems from disruption is to develop a supply chain bill of materials (BoM) corresponding to the software and hardware used in OT, along with attestations amongst vendors and asset owners. A supply chain BoM is a proactive way to understand the inherent vulnerabilities in the system and mitigate them in advance of being exploited. BoMs bolster the trust placed in the digital infrastructure and enhance software supply chain security by sustaining the management of component obsolescence and compliance, along with the seclusion of unsafe segments of a specific product. Adopting BoM tools is becoming increasingly important across various government sectors, as evidenced by the recent U.S. executive order on cybersecurity (NIST 2021). This paper aims to classify BoMs based on structure, functionality, component type, and architecture. The work also discusses case studies to further highlight the benefits of BoMs. In addition, it identifies missing pieces in existing BoM implementations so that future research may identify bounds on where it could expect to make improvements and directly enable researchers to identify promising areas for exploration. Further, the authors provide valuable recommendations to tool developers, researchers, and standardizing organizations (policymakers), additionally benefitting critical infrastructure owners and government executives. This aids in paving a path for future work, thereby, providing suggestions to determine a tool for consumers that best suit their needs.

“…Although company design processes can define the types of design structures and descriptions that will be required for passage through the process in a stage gated manner, there are also circumstances where design structures need to be created without prior knowledge of what the structure would be because it is not always possible to predict reliably future needs. Liu et al and Yin & Ma [10,11] propose featurebased approaches but these depend on a knowledge of the downstream design structures and are, therefore, only applicable to specific cases. The annotation of lightweight shape models overcomes this problem [12] but the annotations are text-based so limited when new structures are required and models become cluttered as the volume of annotations increases through the life of the product [13].…”

Design configurations, such as Bills of Materials (BoMs), are indispensable parts of any product development process and integral to the design descriptions stored in proprietary Computer Aided Design and Product Lifecycle Management systems. Engineers use BoMs and other design configurations as lenses to repurpose design descriptions for specific purposes. For this reason, multiple BoMs typically occur in any given product development process. For example, an engineering BoM may be used to define a configuration that best supports a design activity whereas a manufacturing BoM may be used to define the configuration of parts that best supports a manufacturing process. Current practice for the definition of BoMs involves the use of indented parts lists and dendograms that are prone to error because it is easy to create discrepancies across BoMs that, in essence, are defined through collections of part identifiers such as names and part numbers. Such errors have a significant detrimental effect on the performance of product development processes by creating the need for rework, adding costs and increasing time to market. This paper introduces a design description capability that ensures consistency across BoMs for a given design. A boolean hypercube lattice is used to define a design configuration space that includes all possible configurations for a given design description. Valid operations within the space are governed by the mathematics of hypercube lattices. The design description capability is demonstrated through an early engineering design configuration software tool that offers significant benefits by ensuring consistency across the BoMs for a given design. The software uses and generates design descriptions that are exported from and imported to commercially available design systems through a standard (ISO 10303-214) interface format. In this way, potential for early impact on industry practice is high.
