<![CDATA[The role of the algorithms in software or programming is very important, so it is necessary to understand the basic concepts of the algorithm. Study the implementation and performance of the sorting process using heap sort, insertion sort and merge sort algorithms. The research method for the first stage, the three algorithms are implemented to sort the numbers made by the user, in the second stage the source code for the three algorithms is changed to be able to sort randomly generated numbers with as many numbers as the request from the user. To find out how well the performance in sorting the data, then in the last stage the three algorithms sort random numbers with a predetermined vulnerable number and then the results are compared. Experiments that have been carried out and based on the analysis, heap sort is one of the data sorting methods that are classified as having a high speed, where the complexity and speed of the sorting time needed for the sorting process uses insertion sort and merge sort algorithms which show less consistency in the complexity of time and space. Based on the results of tables and data on the amount of data, shows that the heap sort algorithm gives a very consistent processing time in increasing the processing time to the amount of data.]]>

<![CDATA[This study aims to determine the comparison of the sound pressure level produced by an acoustic sound generator system with surround effects without surround effects. Acoustic sound generating system with surround effects is designed and made as a sound system that produces a surround effect where the resulting sound is divided and distributed over two or many channels (multi channel). This sound system consists of four parts, namely: front cannel, rear surround channel, extra rear channel and subwoofer. This system gets input from the VCD in the form of R and L signals into the AN7397K IC then comes out through four output channels. Each output channel is connected to a 150 watt stereo and mono power amplifier. From the results of research with statistical tests using the t distribution shows that there is a difference in sound pressure level (SPL) between acoustic sound generating systems with surround effects without surround effects at a distance of 1 meter to 10 meters, where the value of the sound pressure level with a sound generator system is obtained. acoustics with a surround effect higher than the sound pressure level without a surround effect]]>

<![CDATA[PT Torishima Guna Indonesia is a manufacturing company that produces water pumps. In a production system that is run using a hybrid, which is where you can make to stock and make to order, but in one product that uses the make to order system, the ETA-N product. ETA-N products are very popular products, but PT Torishima Guna Indonesia often does not meet demand, due to problems on the production floor. PT Torishima Guna Indonesia often accumulates WIP (work in process) in the warehouse, because the spare parts needed are not sent by the supplier or are late in sending spare parts, resulting in increased storage costs. From the problems that have occurred, what is done by implementing kanban is expected to suppress the weaknesses that occur in the production system in the company. Kanban is a pull system approach that relies on authorization to control the amount of production to be carried out by the company, in order to control the raw materials of a product based on forecasting consumer demand. The purpose of this study is to determine the implementation of the kanban system at PT Torishima Guna Indonesia, to determine the factor of late delivery of components for PT Torishima Guna Indonesia, to design a system for providing material supply in the production process so as to reduce inventory, Work in Process (WIP) at each production process. In implementing this proposal, it is evident that the reduction in inventory costs is clearly visible, namely by 45% in 2017 and 72% in 2018.]]>

<![CDATA[Visualization is a tool that makes it easy to understand the information presented in charts and graphs. The purpose is to facilitate data exploration. Therefore, the authors use relationship diagrams as Mathematical Modeling to explore data that has a relationship between tables. The purpose of the study is to map the dataset, which found out a possibility that some errors when entering data. In the mapping process, we use the composition of relations, thus making the number of possible relationships in the mapping. Because of the problem, the table mapping use into a binary relationship diagram based on the number of attributes in a table. The conclusion obtained when using a binary relation diagram is that the more column in a table, the more mapping relationship diagrams must be drawn. Although the relationship diagram becomes very complex, it handled if the tables are correctly normalized.]]>
