Purpose: This research aims to make an update how much volume of cement is needed for Indonesia, to disclose cement consumption for Indonesia and the relationship between cement consumption and several variables as inflators that influence cement consumption.

This research tries to shed light on precise values of logistics costs that so far undisclosed. The values are important for every project planners to evaluate, control and monitoring, and especially imperative for procurement activities. Tender, bidding, and defining the scope of contracts and value can be well organized without time-consuming. This research uses methodology previously developed by Subiyanto (2020a) and discussed only a few particular and directly related to the logistics. The model had been decomposed by utilizing path analysis and the data had been regressed to define variables as the most inflator for logistics. The findings are total logistics costs in Indonesia generally at around 14.6% to total costs of investment. It consists following of insurance cost 0.11%, costs for customs clearance 6.52%, foreign logistics costs 6.62%, domestic manufacture 0.47%, and domestic logistics costs 0.89%. This research is not discussing logistics costs relating to human resources, human travelling, and internal logistics conducted by vendors or contractors as the scope included counted within their procurement contract. These results are important as guidance for project planners, controllers, and other parties to prepare costs more precisely. Negotiating to the banks will be easier as the more precise amount of budgets had been estimated. Due to the important values that have been identified, there will help transparency and governance conducting the projects. Procurement processes involving societies are more objective and better. This is a novelty finding as previous researchers have not decided yet.

Logistics infrastructure is widely known as the most significant economics hurdle in Indonesia over recent decades due to the limited logistics infrastructure. This study aims to examine total logistics costs during the execution of several cement projects in Indonesia within the period 2010-2018. The panel data method of eight cement projects in Indonesia has been developed, analysed, and measured. Due to the limited logistics infrastructures, the logistics cost rose to 27.129% of the Gross National Product (GNP) in Indonesia. Further, this paper provides suggestions for Indonesia's government to develop logistics infrastructure.

This research aims to disclose yearly Pandora boxes to determine precisely variable costs that drawing up of logistics model in Indonesia's cement projects. It begins caused by difficulties to plan an effective projects at the stage of deployment of costs allocation at the preliminary phase. The research period taken was 2010 to 2018 of 8 cement projects in Indonesia by quarterly and had been tested with a statistical tool EVIEWS10.00 to develop robust model. This research employs literature study to assess model previously developed and then reconfirmed by empirical. The model developed is synthesized of 4 dependent variables accordingly defined as foreign logistics costs, domestic manufacture, domestic logistics costs, and total investment costs. Each adjusted R-squared that representing confidence level is consecutively 72.54%, 67.12%, 65.16% and 67.65% or bigger portions are in the model while smaller other in outside model. A 10-variable independent is a new novelty of developing logistics model for executing cement's projects in Indonesia and a concerning significant findings that variable of foreign logistics costs took big portion of the model and therefore must be prior carefully anticipated. This research is giving contribution for planning projects carefully and precisely to avoid budget exceeded generally in every projects.
