Reviewer 1 Report

Comments and Suggestions for Authors

 

The manuscript aims to study the factors influencing the adoption of the Indonesian market to reusing construction waste. The reviewer would like to first thank the authors for their work. However, some concerns are listed below need to be addressed before the consideration of publishing this work:

 The introduction section provides the perception that this study is catered to the Indonesian market. The narrative of the material and methods section needs to be reviewed to follow up on that promise if this was indeed the authors’ intention.

Many of the drivers and barriers discussed seem to be “two sides of the same coin” (e.g., FE7 and FE3). These factors should be reviewed for context and applicability to the market being studied.

The authors mention that the DEMATEL validation process “figured out three invalid driving factors and four invalid barriers factors”. How did the validation process come to this conclusion? And what were the comments of the experts on this fact?

Lines 166-200 should be supported  by a solved example from the data which the authors have worked on. This helps better track the process and validate the results.

Considering that this paper should inform policy decision in the Indonesian construction sector, a “layman term” explanation for the results shown in Figures 1 and 2 is necessary.

Line 404: add the reference to “Hasan’s research in 2004”.

While the authors have provided in their conclusion section a brief discussion on what is the top driver the Indonesian government might pursue to encourage the reuse of construction waste. It would be better if this part could be expanded to include the top three drivers to pursue and barriers to overcome. The authors can even move this piece (lines 403-412) from the conclusion section and create a new “practical implications” section for that purpose.

Reviewer 2 Report

Comments and Suggestions for Authors

This study aims to explore the drivers and barriers to implementing integrated waste management in construction industries. The Content Validity Index and Modified Kappa methods were utilized to validate the indicators from the literature review. A total of 18 driver factors and 21 barrier factors in 6 dimensions have been successfully validated by seven experts. This study then employs the decision-making evaluation and laboratory-based analytical network process to find the weight and relation between each indicator and dimension.

Generally, the topic is interesting, and a systematic study was carried out. This paper is therefore recommended for publication. However, the following issues should be addressed:

1 The novelty of this study is not good enough, and should be strengthen.

2. The title is too long and the abbreviations “DEMATEL-based ANP” are not suitable.

3. Some grammar mistakes and typos need to be carefully examined, for example, in line 105, page of 3, the “manuscript” should be revised as “paper”; in line 108, page of 3, the “discusses” should be revised as “draw”; the “environ-mental” in line 114, page of 3 should be revised as “environmental”.

4. Only seven experts have been invited to discuss the indicators in the Section of 2, did this can represent the extensive situation?

Review Comments

This paper investigates the driving and hindering factors for implementing an Integrated Waste Management System (IWMS) in the Indonesian construction industry using a DEMATEL-based ANP method. The indicators are validated through CVI and an improved Kappa method, and the influencing factors are analyzed for their weights using the DEMATEL-based ANP method. The study finds that awareness is the most significant driving factor, while the lack of education is the most crucial hindrance. This research aligns well with the era of sustainability development, holding significant theoretical importance for the implementation of IWMS in the Indonesian construction industry and enriching the global literature on sustainable development in developing countries.

Recommendations:

1. The paper discusses impacts by providing questionnaires to 7 experts in waste management, which is a small number, and the diversity in terms of fields and levels of the respondents is too narrow.

2. Diagrams and charts need clearer labeling, such as missing axis titles, and the calculation method for the D-R score is not provided.

3. The discussion on results and diagrams is not deep enough, lacking connection with industry dynamic changes and technological iterations, which is insufficient to support the proposed solutions.

Reviewer 4 Report

Comments and Suggestions for Authors

This paper explores the drivers and barriers in integrated waste management in construction industries. This is an important topic as waste from construction or demolition significantly influences the environment. The paper is well written and is within the scope of this journal. There are some points to improve.

(1) Page 2: The authors mentioned that they used the DEMATEL (Decision-Making Trial and Evaluation Laboratory) method for evaluating purposes, but they should clarify the novelty in the Introduction by comparing with existing studies using the same DEMATEL.

(2) Page 3: The reviewer suggests adding a flowchart in the beginning of Section 2 to show the overall procedure of obtaining data, processing, and evaluating. In such a figure, the main techniques can be annotated.

(3) Page 3: The reviewer also suggests adding more details or mathematical formulations for the I-CVI and the modified kappa method. Is there any method that can be used to supplement the modified kappa evaluation Score?

(4) The authors need to reorganize the conclusions in a point-by-point format, presenting only the novelty and key findings. As there are many data involved, the machine learning techniques, e.g. 10.1016/j.jrmge.2022.10.014, can be helpfully discussed.

Reviewer 3 Report

Comments and Suggestions for Authors

The paper utilizes the DEMATEL-based ANP method to study the driving factors and barriers in implementing an Integrated Waste Management System (IWMS) in the Indonesian construction industry. It employs the CVI and an improved Kappa method for the analysis and verification of indicators, and conducts a weight analysis of influencing factors through the DEMATEL-based ANP method. The study found that awareness is the most important driving factor, while a lack of education is the most significant barrier. This research aligns well with the era of sustainability, offering significant theoretical implications for the implementation of an IWMS in the Indonesian construction industry and enriching the literature on sustainable development in developing countries globally.

The author has enriched the analysis related to driving factors and barriers, providing valuable insights into the potential for implementing integrated waste management systems. By improving grammatical expression and presenting a research flowchart along with the specific process of data collection, the paper enables readers to better understand the subject.
