Abstract

The Gajah Mungkur Reservoir is one in all the most largest dams or reservoirs in Java which is categorized as a multipurpose reservoir. With various benefits, it is necessary to forecast the inflow discharge to avoid excess or shortage of water in the reservoir as well as errors in water disposal. A common mistake is the release of water which can cause flooding in areas lower than the reservoir. Discharge forecasting can also be used to plan water allocations such as power generation and irrigation. Changes in inflow discharge that occur are always fluctuating, so from these problems forecasting inflow discharge is needed to overcome the large amount of water discharge that comes out. The data used is inflow discharge from January 2009 to December 2019 and the method used is Extreme Learning Machine (ELM) because it has fast learning speed and good generalization. The test results obtained are the optimal number of features as many as 7, the optimal number of hidden neurons as many as 9, with the percentage of training data 80% and 20% of the test data producing RMSE 28.7303, MAD 21.8002 with a runtime of 0.0272s. With an RMSE value that is far from zero, the error rate obtained is high and bad. And also with a runtime that is in seconds or less than seconds, this research also confirms that ELM has advantages in fast learning speed.

Abstract

Product distribution companies require cost-effectiveness and efficiency, one of the supporting factors a determining the optimal distribution route. The distribution route is closely related to the Traveling Salesman Problem. In the distribution process from the warehouse or stock point, Nganjuk PT Indomarco Adi Prima has a Multiple Traveling Salesman Problem which involves more than one salesman in the distribution process. To solve MTSP problems, you can search for it by traveling to all possible routes. However, when there are more routes, more time is needed. This research is an effort to optimize the distribution route of PT Indomarco Adi Prima's Nganjuk stock point products using the K-Means and Ant Colony Optimization (K-ACO) methods, in which the K-Means method a used to divide MTSP problems into smaller problems than each problem. Then each of these problems will find the shortest route with ACO. In the tests carried out, K-ACO can save salesmen a traveling distance of 565.801 km. While testing using the Silhouette Coefficient, K-Means resulted in a 76.72% better solution when compared to the results of real sales trips. These results indicate that the use of K-ACO can minimize the total distance traveled from the problem.

Abstract

Internet of Things is a topic of discussion that is growing rapidly now. One protocol commonly used in communication between IoT devices is MQTT. In communication, these devices are interconnected with brokers MQTT. But along with the growth of IoT devices that make connection requests to MQTT brokers, MQTT brokers have decreased resources, and become a single point of failure. Therefore we need MQTT brokers who are able to have auto scaling capabilities so they can adapt to the growing demand for connections from IoT devices. In its implementation, MQTT broker is placed in a container and orchestrated with kubernetes so that it has the ability to auto scaling. In testing, a comparison is made between MQTT brokers with auto scaling capability and without auto scaling capability. Testing is done by measuring the maximum number of clients that can be connected, and the number of connections lost at the time the test is running. As a result, MQTT brokers with auto scaling capabilities can receive connection requests from clients 27% better than MQTT brokers without auto scaling capabilities. Whereas in measuring the number of disconnected connections, MQTT broker with auto scaling capability is able to provide 54.42% fewer disconnected connections than MQTT broker without auto scaling capability.

Abstract

The school website is a set of page that contain school information connected to each other with a link. An example of information that can be shared by the school is the student's rating. Currently, the process of submitting the value of student report card at SD Negeri 1 Gunung Madu is done by meeting parents or guardians directly. However, the process used today is having problems when the COVID-19 pandemic hits as it is now. With the COVID-19 pandemic, zoning systems were implemented in various regions including SD Negeri 1 Gunung Madu. Zoning enforcement causes the process of delivering student report card grades directly can not be carried out. Based on the problems that arise, the school website is created that aims to convey and manage the value of student reports. The development of the school website at SD Negeri 1 Gunung Madu using waterfall method resulted in 46 functional needs for administration, 29 functional needs for homeroom parents and 4 functional needs for students after passing 2 iterations. The implementation of this school website uses the AngularJs framework and the PHP framework SLIM. Functional testing includes unit testing and integration testing. Both unit testing and integration testing successfully obtained passed status. In addition, validation tests out of a total of 80 test cases get 100% valid results. Non-functional testing includes compatibility testing using website testing tool SortSite and usability testing using System Usability Scale (SUS).
