In this era of rapid technological development, many things are developing rapidly, one of which is the development of games in the world. Many games have been made by the developers themselves, so there are already many variations of the type of game itself, one of which is the endless runner genre game. In the endless runner game itself, there is an object that we have to create massively and repeatedly which usually applies to how to create and delete these objects massively. However, there is a better method in optimizing the implementation for massive object creation and deletion with the object pooling method, where the difference is in this method uses how to activate and deactivate objects. So in this way, it will optimize the game so that its performance does not drop and memory usage does not take up much space.

In human life the use of electrical energy is very important and needed, but over time the use of its consumption is increasing. Therefore, it is necessary to save electricity consumption activities. This effort is known as energy conservation, one of which uses the energy audit method. Energy audit is to calculate the level of use or Energy Consumption Intensity (IKE) in the Untirta Integrated Laboratory Building whether it is efficient in the use of electrical energy. Collecting data related to electricity usage, building profiles, and observing lighting loads, air conditioning/air conditioning loads and other loads. The use of the IKE formula as a form of analyzing the data. The results of the study stated that the IKE value in the Untirta Integrated Laboratory Building was 38.019 kWh/m2, from this value it can be seen that the IKE is efficient. This is based on the parameters used by ASEAN-USAID of 240 kWh/m2. There is an addition in saving energy if in the future there are additional burdens such as laboratory equipment or electronic goods. These savings can be made by using LED lamps and replacing TL lamps or using lamps with a lower wattage than the previous lamp and can be done by reducing the duration of usage in consuming electrical energy.
