Abstract

This research is focused on the analysis of delays or risks to the implementation of the "Procurement and Installation HVAC Installation" contract at West Madura Offshore Oil Company, which has a working area in the Offshore area. This study uses the HOR (House of Risk) method as an alternative to the ISO31000: 2009 risk management method that has been used internally by West Madura Offshore Oil Company The basis for selecting the HOR (House of Risk) method is the existence of a tool to see the impact (severity) and relations (relations) between the event of a delay and the factoring agent. In identification of the cause of the delay the method used are collecting data primary through Focus Group Discussion between Internal Expert and Secondary data which use project data for Offshore HVAC Project in the period of the year 2016-2018. The HOR (House of Risk) method in conducting this process is presented as follow review historical data and related document, Focus Group Discussion as information gathering techniques, Risk analysis and Risk Register. There are five significant risks from the results of research using the HOR (House of Risk) method, namely Poor-quality shop and coordination drawings, weather constraints, limited quantity and quality of HR (contractors and subcontractors), Absence of duct fabrication workshops at the site and lack of communication between contractor and subcontractor.

Abstract

The Indonesia Mining Growth Program (P3I) is a development project activity for nickel Mining Enterprise and Processing Plant in the "X" Region in Sulawesi. This research will design a risk management framework for P3I by implementing Enterprise Risk Management (ERM). In this study, the method is used to analyze the potential operational risks that exist in P3I namely the House of Risk (HOR) model. The results of the identification of risk events in the operational business processes of P3I found 25 risk events divided into each business process, namely 8 risk events in the mine planning process, 7 risk events in the design implementation process, 8 risk events in the production process, 1 risk event in the product delivery process and 1 risk event in the process of returning waste from Processing Plant. Thus, the results of the identification of risk triggers (risk agents) found 23 risk causes (risk agents). The result of the Aggregate Risk Potential (ARP) recapitulation is an output calculation based on the HOR model phase 1, there are 7 top-ranked risk agents since it is considered to be able to hamper the company's goals. Thus, in determining the preventive actions, 17 preventive actions were obtained, which were then put into the HOR phase 2 model to rank the most effective prevention measures based on cost and resources.

Abstract

Mall is a shopping center consisting of the main tenants (anchors), retail, shops, services, and public facilities that are built, managed, and arranged by the manager with the aim of conducting interaction between visitors and sellers. In 2018 Surabaya City had 33 malls or 50.77% of the total number of malls in East Java, this shows that the mall population in Surabaya City is very high. Mall XYZ is one of the malls that stood in the city of Surabaya and has been operating for one year. This mall still has not shown a development that is not optimal because of the many complaints from tenants to building management related to the sale of products that do not reach the target, as a result tenants often violate the rules (house rules) that have been set by managers to break the cooperation contract between building management and tenants unilaterally . To find out the cause of these conditions, text mining methods are used to filter reviews from visitors filtered from the Mall XYZ Google page. of the existing reviews classification will be based on reviews that contain positive and negative sentiment. review with positive sentiment becomes an appreciation that must be maintained and improved while a review containing negative sentiment becomes a complaint that must be addressed by the building management as the mall manager.

Abstract

Gypsum is a by-product of the Phosphoric Acid factory PT Gresik Petrochemicals; it is produced around 1,200,000 tons/year. In order to reduce the amount, an effort needed to use gypsum as fill materials. For this purpose, the problem needs to be considered is that gypsum should not contain substances that harmful to the environment and meet the fill materials requirements. In order to answer all these questions, chemical tests were carried out to determine its heavy metal content. Gypsum plasticity and its particle size distribution were determined by conducting Atterberg limit and sieve analysis tests. Compaction test and CBR test were also carried out to determine the density and its strength. Those results were then analyzed using "The Fifteen Point Method" to obtain a relationship curve between dry density (d) and soaked-CBR. This curve was important to determine the soaked-CBR that can be achieved by gypsum materials in the field with different compaction energy 90%, 95%, and 100% of maximum compaction energy. Chemical test result shows that all heavy metals content in gypsum material are far below the regulatory limit; therefore, it is safe for the environment. Besides, Gypsum is non-plastic (NP) material and it is classified as A-4 (AASHTO) or SM (USCS); it means that Gypsum is very good for fill materials and safe to the environment. In addition, the result from the Fifteen Point Method shows that the minimum soaked CBR value is 13% achieved by using 90% of maximum compaction energy with 30-40 % of water content. It means that the gypsum material can be used as selected fill material because it fulfils its requirement where IP10%.

Abstract

Salt is a very important commodity for human life. In addition to consumption, salt is also needed in several industries, including for the Chlor Alkali Plant (CAP) industries, pharmaceutical, and non-CAP industries such as petroleum, salting, and others. The demand for industrial salt in Indonesia continues to increase every year along with the growth and development of industries in Indonesia. However, the salt produced by Indonesian salt farmers is still low in quality and can only meet the needs of consumption salt because they only contain about 94% to 95% NaCl. Therefore, local salt is difficult to be absorbed by with salt-based products industry because its purity level does not meet the industrial standards. As a result, imports of industrial salt will increase because local salt cannot meet the industry needs. This study aims to build a conceptual model in order to improve the quality of salt in Indonesia in order to produce a good quality salt that meet the industrial salt standards and can be absorbed by the industrial sector in Indonesia with system dynamics approach. The results of this study are conceptual models regarding internal and external factors that influence the improvement of salt quality to meet the needs of industrial salt. The model can be used by the government and related parties in developing strategies and policies related to industrial salt cultivation. Further research can be done by developing several scenarios to predict future salt cultivation systems.

Abstract

The type of contract for the road project used in PT Pelabuhan Indonesia III (Persero) is currently using the type of General Contracting. The contract is conventional and is considered to have many weaknesses. To obtain more optimal project results and maintenance can run optimally, in addition to improving quality control by the project supervisory team, one way that can be done is to change the use of innovative types of contracts. namely Performance Based Contracts (PBC). When implementing the PBC for the first time, there are several things that must be prepared, one of which is the readiness of the owner and contractor. Analysis in this study uses Structural Equation Modeling (SEM). The results obtained are that the variable readiness to use PBC has a positive effect on the application of PBC. If the readiness variable increases by one unit and the other variables are considered constant then the PBC implementation variable will increase by 0.390.
