- 3. A. BACKGROUND In this research of this paper is about how the measurements of trade level of productivity. Productivity is a key factor that companies should track to ensure their long-term viability. In fact, productivity can be a real source of competitive advantage. In the macroeconomic sense , it is a benchmark of a country’s living standard and reflects the overall competitiveness of an industry and economy (Jergeas et al. 2000). as a critical component that can be used to asses the overall productivity of industry and it was done by any research that has been conducted to i nvestigate the challenges that contractors and subcontractors face in measuring productivity accurately at the trade level. Productivity is defi ned as the relationship between output produced and one or more of t he inputs used in the production process (National Research Council 19 79).

PROBLEMS The problem that will be discussed in this paper is about the critical challenges and also about the difficulties that contractors and subcontractors encounter during trade-level pro-ductivity measurem ent, and will identify solutions that can be used effectively to deal wit h these challenges. So this paper is also did any research to find the best solutions that will be identified and analyzed statistically. WHAT’S? Challenges Solutions

- 6. D. THEORETICAL BASIS To know the role that plays in productivity to develop a count ry and how big the effects are , so we have to measuring the impact of productivity construction. In the macroeconomic sense, it is a benc hmark of a country’s living standard and reflects the overall competiti veness of an industry and economy (Jergeas et al. 2000). Despite its high impact, productivity improvement in the construc-tion industry is still an area in which much research work needs to be done (Ranasi nghe et al. 2012). Understanding productivity in the construction indu stry is a complex and elusive prospect, and the task is made more di ffi-cult by the very nature of the industry (Bernstein 2003). Accord-ing to Chapman and Butry (2009), the nature of the construction process leads to the necessity of measuring construction pro-ductivity at thre e levels: task, project, and industry. It makes the conclution is the pro ductivity is very important so that the competitiveness can be improv ed in industry and economy.

- 11. F. CONCLUSION This study aimed at identifying the challenges encountered b y contractors when measuring trade-level productivity and proposing plausible solutions to overcome these challenges. The literature revie w carried out for this study revealed that trade productivity measure ment is not only affected by challenges that stem from the trades th emselves but are also influenced by the nature of the industry and th e type of contractor firm. In addition, the survey revealed that 62% of the respondents did not have policies related to productivity measure ment at their firms, indicating that most of the contractors were not proactive in this area, although they did acknowledge its importance.

ADVANTAGES • Unfortunately, this paper didn’t use more data. So I think it is too small number of data because only use 42 respondents, and I espectif it is use more data so that it makes more reliable. WEAKNESS

Editor's Notes
- This paper is using the methodology of Case studies (field); research that aims to intensively study the background of the current situation and the environment intraksi a social unit, whether individuals, groups, institutions or communities. And also using any methods to collect data information, for example in this paper for the method to collect data is through interview with four industry experts and a survey ques-tionnaire with five main sections was developed. The first section captured general information about the companies and the re-spondents. The second section asked about the contractors’ internal policies for productivity measurement. The third section posed questions about the availability of trade-level productivity mea-surement data. The fourth section covered challenges that affect trade-level productivity measurement and The last section of this questionnaire aimed to identify the effectiveness of the solutions to overcome the challenges.

- Respondents were asked to rate their impor-tance using a five-point Likert scale, where 1 = of least importance and 5 = very important. The last section of this questionnaire aimed to identify the effectiveness of the solutions to overcome the challenges. Respondents were asked to rate the effectiveness of the potential solutions using a five-point Likert scale, where 1 = ineffective and 5 = very effective.
- ). Firm-Related Challenges Under the category of firm-related challenges, in Table 2 (Column I), the lack of a proper system to measure productivity (F5) was ranked with the highest mean score of 4.40 followed by the second-ranked challenge, the time and manpower required to measure (F4), with a mean score of 4.07. It can be interpreted from these results that most contractors lack a productivity measurement system and confirms that the work required to measure productivity is in-deed resource consuming 2). Trade-Related Challenges As shown in Table 2 (Column I), the highest-ranked trade-related challenge was T5, with a mean score of 4.33, representing the dif-ficulty that contractors encounter in obtaining accurate productivity data due to the nature of the trades on site. This was followed by the second-highest-ranked challenge T2, with a mean score of 4.29 showing that contractors often encounter difficulty when measuring trade work hours. The third challenge, T4, with a mean score of 3.93, indicated that the attitude of employees toward productivity measurement plays an important role in ensuring effective produc-tivity measurement. 3). Comparison of Challenges between Main Contractors and Subcontractors To see if the views of main contractors and subcontractors were different in terms of their attitude toward the difficulties in meas-uring productivity, further analysis was performed against the data categorized into the two groups, as summarized in Table 2 (Column II). Looking at the main contractors it becomes clear that to them, the extensive use of subcontractors (mean score of 4.67) was their most critical challenge. This was followed by the lack of direct benefits from measuring productivity and the lack of a proper productivity measurement system, with mean scores of 4.56 and 4.37, respectively 4). Comparison of Challenges by Specific Trades (Form Work and Rebar Work) In the survey, respondents were asked to indicate the three most important trades whose productivity should be measured. The re-spondents selected form work and rebar work as the top two trades, both of which had percentages of 35%. As a result, it is imperative to address specific challenges posed to the trades to facilitate accurate productivity measurement.
- 1). Industry-Related Solutions Column I in Table 4 shows that the top-ranked solution for industry-related challenges was IS9, with a mean score of 4.69. This corresponds to the response calling for the simplification of productivity measurement with a focus on capturing only the most important trades as the most effective solution to industry-related challenges 2). Firm-Related Solutions Under the category of firm-related solutions in Table 4 (Column I), FS2 was the most effective solution with a mean score of 4.57. One possible reason is that contractors feel that measuring productivity is complex and only important trades should be measured in order to increase efficiency in the measurement process Almost all of the firm-related solutions had a mean score of more than 4, except for FS4 and FS5. This result suggests that respondents believe most proposed firm-related solutions would be effective. 3). Trade-Related Solutions As shown in Table 4 (Column I), creating a culture for productivity measurement, TS5, was cited as the most efficient trade-related sol-ution, with a mean score of 4.48. This result implies that a positive culture for productivity measurement is important for the industry when dealing with trade-related challenges 4). Comparison of Solutions between Main and Subcontractors
- COMMENT Adventages : In my opinion this paper is good structured, we can knows clearly because the step by step is pulled out. It has a good topic to be discussed. Weakness : Unfortunately, this paper didn’t use more data. So I think it is too small number of data because only use 42 respondents, and I espectif it is use more data so that it makes more reliable.
