This study aims to develop a robust prioritization model for municipal projects in the Holy Metropolitan Municipality (Makkah) to address the challenges of aligning short-term and long-term objectives. The research explores How multi-criteria decision-making (MCDM) techniques can prioritize municipal projects effectively while ensuring alignment with strategic goals and local needs. The methodology employs the analytic hierarchy process (AHP) and exploratory factor analysis (EFA) to ensure methodological rigor and data adequacy. Data were collected from key stakeholders, including municipal planners and community representatives, to enhance transparency and reliability. The model’s validity was assessed through latent factor analysis, confirming the relevance of identified criteria and factors. Results indicate that flood prevention projects are the highest priority (0.4246), followed by road projects (0.3532), park construction (0.1026), utility projects (0.0776), and digital transformation (0.0416). The study highlights that certain factors are critical for evaluating and prioritizing municipal projects. “Capacity and Demand” emerged as the most influential factor (0.5643), followed by “Strategic Alignment” (0.2013), “Project Interdependence” (0.1088), “Increasing Investment” (0.0950), and “Risk” (0.0306). These findings are significant as they offer a structured, data-driven approach to decision-making aligned with Saudi Vision 2030. The proposed model optimizes resource allocation and project selection, representing a pioneering effort to develop the first prioritization framework specifically tailored to Makkah’s unique municipal needs. Notably, this is the first study to establish a prioritization method specifically for Makkah’s municipal projects, providing valuable contributions to the field.
Sustainability in road construction projects is hindered by the extensive use of non-renewable materials, high greenhouse gas emissions, risk cost, and significant disruption to the local community. Sustainability involves economic, environmental, and social aspects (triple bottom line). However, establishing metrics to evaluate economic, environmental, and social impacts is challenging because of the different nature of these dimensions and the shortage of accepted indicators. This paper developed a comprehensive method considering all three dimensions of sustainable development: economic, environmental, and social burdens. Initially, the economic, environmental, and social impact category indicators were assessed using the Life cycle approach. After that, the Analytic Hierarchy Process (AHP) method and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) were utilized to prioritize the alternatives according to the acquired weightings and sustainable indicators. The steps of the AHP method involve forming a hierarchy, determining priorities, calculating weighting factors, examining the consistency of these assessments, and then determining global priorities/weightings. The TOPSIS method is conducted by building a normalized decision matrix, constructing the weighted normalized decision matrix, evaluating the positive and negative solutions, determining the separation measures, and calculating the relative closeness to the ideal solution. The selected alternative performs the highest Relative Closeness to the Ideal Solution. Lastly, a case study was undertaken to validate the proposed method. In three alternatives in the case study (Cement Concrete, Dense-Graded Polymer Asphalt Concrete, and Dense-Graded Asphalt Concrete), option 3 showed the most sustainable performance due to its highest Relative Closeness to the Ideal Solution. Integrating AHP and TOPSIS methods combines both strengths, including AHP’s structured approach for determining criteria weights through pairwise comparisons and TOPSIS’s ability to rank choices based on their proximity to an ideal solution.
In Indonesia tax reform has undergone multiple revisions in recent years, all within a brief timeframe. Digital tax reform in Indonesia began with significant milestones in recent years to adapt to the digital economy’s challenges. The specific start date for digital tax reform in Indonesia can be traced back to the passing of the Tax Regulations Harmonization Law on 7th October 2021, which officially became Law No 7/2021 on 29th October 2021. This law marked a crucial step in Indonesia’s journey towards modernizing its tax system to address the implications of the digital economy. The provisions of this law have varying effective dates, such as for income tax purposes from the 2022 fiscal year and for VAT purposes from 1st April 2022. These changes under the Tax Regulations Harmonization Law are extensive and wide-reaching, signifying a pivotal moment in Indonesia’s digital tax reform efforts. This shows that the Indonesian government intends to radically overhaul the tax system, yet there are inconsistent approaches to deciding on the long-term course of tax policy. It is critical to investigate the concept of tax legislation in Indonesia in order to provide legal clarity on digital tax reform. Normative juridical research methodology is employed, together with a qualitative research strategy and descriptive-analytical research specifications. The findings suggest that the Indonesian government’s efforts to establish strict policies governing taxes on digital activity are inadequate and uneven. In order to apply to digital platform enterprises, the definition of permanent establishment as outlined in a number of national regulations must incorporate a substantial economic presence criterion. Legislative progress toward the establishment of a framework for digital tax collection is necessary to mitigate the possible income loss of states in this area, which could result from the rapid advancement of information technology. The OECD consensus is still in the process of drafting an international tax reform that will require adjustments from national tax reform. Therefore, it is imperative that the Indonesian government establish a thorough framework for tax regulation that can ensure robustness, economic efficiency, fairness, against motivation compatibility, administrative ease, and avoidance.
