<![CDATA[The advancement in the field of science and technology brings forth new problems and challenges. One such problem is the need to simulate properties of objects or situations due to the real-world conditions being either costly or impossible to achieve. Interactive cloth simulation is one of the fields which requires a simulation to be run in real-time. A realistic simulation requires a heavy computational workload, and as such will hinder the purpose of running the simulation in real-time. Optimization using pure algorithm and math are likely to find balance between accuracy and speed. This research introduces an optimization using parallel computing on GPU to speed up the simulation without reducing the accuracy. The simulation is based on continuum mechanics due to its ability to display realistic physical properties of cloth. The model dynamics is discretized using FEM, then a corotational formulation is used to compute the elasticity property of cloth. This research uses CUDA platform developed by Nvidia to deliver the parallelization. The testing results shows that there are little but acceptable accuracy differences on the parallel version of the simulation. The speedup happens when the structure of a function is ideal for GPU parallelism. A full GPU parallelism causes massive overheads in functions that are not or at least directly parallel compatible. Choosing functions that are compatible or modifying ones to fit the ideal parallel condition will make significant speedup.]]>

<![CDATA[One of the more famous games lately is the Werewolf game. This game requires 15-20 players once a game. In fact, it is very difficult to gather 15-20 players in one place and at the same time. In addition, from existing werewolf game apps, to play with friends around very hard. Therefore, made this Werewolf game with Near Me feature using GPS. Features Near Me itself is a feature that displays a list of game rooms that players are near the user. So the players do not need to spend time looking for the name / game room number to play with. To get the distance from Near Me this is used GPS from each player and will be measured how far distance of player in game room with user use formula to measure distance with latitude and longitude.The steps of making this thesis first is to prepare the game database using MySQL. Then create a game interface using Android Studio, create game server using Firebase. After that, connect the database and game server to Android Studio. Create support features of the game, and do an overall check on the game.The final result of this application is a Werewolf game with features Near Me. After going through several testing phases, this app can be played up to a maximum of 18 players in 1 game room and can have 10 game rooms. Based on the questionnaire results, the Near Me feature was found to facilitate the users in terms of finding the game room when the users were playing together.]]>

<![CDATA[Nowadays, the word culinary is currently popular. Many restaurants and cafes were built to fulfill the enthuasism from customers in trying new foods and recipes. Lots of innovation and creativity from the owner were used to attract the customers by creating a new recipe and food. The enthuasism of people in culinary doesn’t stop right there. Their enthuasism leads them to share those food which they ate to the social media so that other people could also know and tried. However, it has limitations and drawbacks because these recipes have not been tested for quality. Not only that, but also many people feels like cooking is difficult because the lack of steps and pictures in a recipe. The lack of steps and pictures in a recipe makes the enthuasism decreasing.Technology is growing rapidly. Many Android developers were started to make an application or software in order to help fulfilling people needs and problems. The technology which are developed nowadays, allows to eliminate the deficiency of a problem. By creating this application, it will help people know which recipe is worth to try depending on the number of likes and comments from the users. Cookpedia also can filter the recipes based on likes so that users can see the recipes which are popular.]]>

<![CDATA[Company X is an electronics retailer company operated in Surabaya city. The company is trying to improve their customer satisfaction by doing some evaluations and enhancement on their existing business processes. One of them is the process of goods delivery services. Some shortcomings occur in the process. For example, it is difficult to determine the order of the delivery routes, especially if there are some customers who have preference delivery hours. Another thing, the company cannot provide any information about the time estimation of the goods arrival that makes their customer feel bad about the delivery services. Because of these problems, the company needs a system that is capable of providing the route sequence recommendation and also giving information about estimation of goods arrival.The system is implemented on website by using codeigniter framework and SQL Server as the database. In this system, the first process is matching the addresses with the response from Google Maps API. This Google Maps API responses are being used in the next process which is calculating route. In order to perform the calculations, Google Maps API has already provided a free of charge service that is capable of giving the best waypoint through the maximum of 8 points addresses. However, the amount of the addresses in one shipment is usually more than 8 addresses. Therefore a method of clustering using K-Means is needed in order to make a group of delivery area into 8 clusters. By then, the route calculation can be done by using the clusters.The end result of this program is a shipping information system for administrators and drivers of the company. This system is able to provide recommendations for the selection of goods delivery routes and information on the estimated time of goods delivery. Based on some testings, the system can perform route calculations with an average time calculation of 133 seconds for 30 destination routes.]]>

<![CDATA[Sometimes to get information about the lectures, the students are a bit distressed. Often also when it comes to administration, students have not received information about the required lectures. This causes the students to be rarely or even never at all to go to the administration and tend to just wait for information from friends who sometimes can cause miss communication.Seeing the usefulness of bots that can help the work and daily activities of humans, finding information and gathering information, Telegram created a bot named Bot Telegram. With this Telegram Bot can help the administration / lecturers in conveying information about the lectures to students appropriately and quickly. In addition to providing information, in Bot Telegram it can send a file and then download the file. It can also assist lecturers in delivering lecture materials. Lecturers can upload the material into the Telegram Bot then students can download it from the Telegram Bot.This telegram bot application helps the administration and lecturers to convey information to students. Administrative officers are very helpful with the application of this Telegram bot let alone how to use this application is quite.]]>

<![CDATA[X Company provides various kinds of electronic things and home appliances, to fulfill all sales transactions on every branches store then it is necessary to have many kinds of assets likes vehicles for delivery services, storefronts for items display and many other needs. And of course every assets need some specific types of maintenances. For now, every process of scheduling maintenances, registering maintenances and recording maintenances realization are done by written manual on paper or by direct spoke to each other’s. The current applied process will have some consequences such as forgetting some assets maintenance and difficulties in creating reports because the data is written on the paper. So it is needed to have a system that records all the broken assets reports, maintenance schedules and maintenance realization properly.To resolve this issue, a system based on Computerized Maintenance Management System(CMMS) with some adaption to the current process of the company that obtained from the direct interview will be created. The system will be made based on web based system using a programming languages such as HTML, CSS, Codeigniter Framework based on PHP, JavaScript, Ajax and using SQL Server as database.The conclusion after finished to develop the system are the scheduling process is have worked correctly but with some exclusion that allow to work overtime with PIC Aset approval and the spare part stock forecast also worked correctly for fulfill the spare parts requests but will not worked to fulfill abnormal requests.]]>
