1. What is the annual cement consumption per person in developed countries?
In developed countries, the average annual cement consumption per person is approximately 250 kilograms. This data is based on the assumption that cement is an essential ingredient in construction and physical groundworks, and it cannot be substituted with other materials. The prediction of cement consumption is calculated based on the number of people residing in a certain area. For example, in 2010, Indonesia had 245 million people, which would require about 61.25 million tons of cement annually. This prediction led to the construction of numerous cement projects in Indonesia from 2010 to 2018 to support the massive infrastructure strategy. The study aims to explore project bottlenecks and improve management in cement projects, providing valuable insights for investors and the Indonesian government.

2. What techniques were used in the research method?
The research method involved three stages: a questionnaire survey, issue discussions, and an evaluation workshop. The techniques were advised by Walker & Harland (2008) and included the analytical hierarchy process (AHP) and exploratory analysis. AHP is a part of the multi-criteria decision-making (MCDM) technique to resolve uncertain issues, while exploratory analysis considers various alternative perspectives on different stages. The methods aimed to increase reliability by using various techniques, including descriptive analysis and qualitative techniques with descriptive statistical tools. The process started with case studies and 31 cement projects from 2010 to 2018, followed by exploratory analysis and AHP in the second phase, and argumentation, standings, and reasons in the third phase to justify the variation in project completion time. The methods are principally mixed interdisciplinary studies that involve discussion, coordination, and management innovations.

3. What causes delays in project completion?
Based on the results, delays in project completion are primarily caused by the preparation and operational stages. The table shows that each project title includes the stage of preparation, phase of accomplishing engineering, procurement, construction (EPC), testing operations in the commissioning stage, and schedule of closure projects. The substance of EPC projects is standard for every project practitioner, and they must perform all matters of the projects to the end. However, in Indonesia, the preparation stage is generally not included in the EPC scope, but it takes approximately 37.5% of the total length of the whole schedule. This stage has seized the schedule for at least 18 months and remained uncertain until the end of the project. Experts can stand based on their professional experience, while others may deliver different considerations. The results concluded that preparation and operational projects were the sources of delays, and these issues became a focus of discussion in meetings through an analytical hierarchy process.

4. What is the primary cause for project delays in EIA?
The primary cause for project delays in Environmental Impact Analysis (EIA) is the delay in obtaining approval for the EIA. The EIA document is a crucial instrument of environmental assessment that must be compiled by certified entities with the exclusive right to conduct EIA processes. The Minister of Environment Decree No. 5 of 2012 outlines the types of business plans and activities that require EIA. The EIA consists of terms of reference, environmental management plan (EMP), and environmental monitoring plan (EMoP). Every project owner must perform an EIA before construction projects, although the scale and scope of projects may be optional for EIA. The government of Indonesia has implemented EIA management, with large projects requiring EIA and limited projects requiring environmental permits. Indonesia Law No. 32 of 2009 mandates the presentation of EME, EMoE, EMP, EMoP, EIA, and SCEM documents for environmental permits. The average time to complete these documents ranges from 12 to 24 months, and some projects did not complete the EIA, leading to construction halts.
