Haul road in open mine has short durability. It is because haul road is constructed without asphalt/concrete pavement and passed by big vehicle with heavy load. This research focused on grader route and schedule optimization in coal haul road maintenance. Optimization model in this research is designed using Bandit Algorithm. The objective of the optimization model is to minimize the maximum penalty.

We initiated a new SEMS Lab Class for our new Lab Assistant that will teach a combination of soft skills and hard skills of becoming a System Engineer. The class will run for 2 semester, with 14 meetings in each semester. Even though it will not be recorded in their academic transcript, the class still works as a regular class where attendance, assignments and tests will be marked accordingly and put into their certificate of completion.

Educating society about energy transition through excitement of a game? Why not!

Transergy is a digital serious simulation game about energy transition as the learning instrument for public education. The development of the game is in accordance with the method of game development by Duke and Geurst (2004). There are four phases to create a game start from setting up the stage for project, clarifying the problem, designing the game, developing the game and the deployment of the game. The first phase has been accommodated by above mentioned paragraph. The second phase is about defining the learning purpose and learning point through game conceptualization and learning model. Transergy game has a concept of simulating the mobilization when using oil as the fuel and then giving the explanation about conversion from oil to natural gas. After the player understand about the conversion, there are some given conditions that will affect the player decision to convert to natural gas. The comparison of expense, carbon emission, health and social indicator before and after the conversion is displayed to give a better comprehension about the advantages of having conversion.

The 2nd Asia-Pacific Region System Dynamics Conference of the System Dynamics Society were held at UTown, National University of Singapore. The theme for this conference is Charting a Path to a Humane and Sustainable Future: Asia’s Leadership Role. The conference brought together various disciplines that have been using Systems Thinking, System Dynamics and Systems Engineering approach in understanding and solving problems. The conference seeks to popularize and extend systems thinking and System Dynamics modelling in the Asia-Pacific Region by facilitating interactions between practitioners from the region and around the world, introducing newcomers to the field, and keeping practitioners aware of current developments.

Indonesia is aware to the carbon dioxide gas emission issue. There are a few technologies that have been used to reduce the emission, such as: using the alternative energy which produce cleaner emission than CO2, using a cleaner technology (in transportation), reducing the use of fossil fuel, etc. Carbon capture and storage technology is still new in Indonesia, and there is no enough information and study on it. The researcher in Universitas Indonesia (majoring Industrial Engineering) helps to find the answer to this new technology. Is Indonesia ready for new technology?

Green house gases (GHG) emission is one of the environmental issues that hasn’t been resolved and continued to increase annually. Carbon dioxide gas is known as the largest contributor for GHG emissions. This environmental issue also happens in Indonesia as a developing country which has focused on…

The existence of weakening coal prices, which decreased from year to year, causing the mining sector, especially companies engaged in coal experienced significant negative impacts. One of the most essential where companies are not experiencing growth on corporate profits, but declined.

Based on these phenomena is the only way for the company to continue running the business activities through efficiency measures on many things to be able to cover operational costs. One of the efficiencies that can be done such efficiency on the operational side. As mentioned by Alarie & Gamache (2002) and Ercelebi & Bascetin (2009) the material transportation represents 50 per cent of the operating costs for an open pit mine. Therefore, one of the efficiencies that can be done and has a substantial impact through efficient on truck dispatching problem in the mine area

It’s inevitable that the price of commodities in the eastern part of Indonesia is much higher than in the west. The unbalance economic growth between these two parts of Indonesia, might be one of the reason. Hence, the main trade activities happen mostly in the west, especially in Java island which could be called as the center of this country.

Liner shipping company, as the provider of maritime logistics services, is looking for technology for optimizing their cost planning in operating and enhancing their fleets. The purpose of this plan is to make the capacity of their fleets matches the demand of container. The main goal for every company is of course to gain maximum profit. But the high of logistic cost and the unbalance trade activities in Indonesia might be the problem for liner shipping company to achieve that.

Have you ever thought about how your soft drinks, or your lotion, could arrive in the shelf even before you need it? That effort to make sure you get what you want when you step into the store is called Supply Chain Management (SCM). SCM is indeed important not only for customers, but also for the company. Every company tries to manage its supply chain efficiently and effectively, as SCM alone costs 30% – 70% of the total of production cost. However, managing a supply chain is not an easy job to do.

In order to enhance the knowledge of SCM, especially for students, SEMS researchers have created a SSG named H2! Supply Chain Management Game.

“A game could makes you forget that you are actually learning. Packaging a very complicated and complex reality in to a simple learning tool is what Serious Simulation Game designed for.”
