Abstract

Breast cancer represents about 12% of all new cancer cases and 25% of all cancers in women. Early detection and classification of cancer is essential to save a person's life. The causes of breast cancer are multi-factorial and involve family history, obesity, hormones, radiation therapy, and even reproductive factors. Each year, one million new women are diagnosed with breast cancer, according to a World Health Organization report, half of them will die, because it is usually too late when doctors detect cancer. After the selected variable is then evaluated based on certain criteria. If the first selected variable meets the criteria for inclusion, the selection continues. The procedure stops, if no other variables meet the entry criteria and adds the variables one by one. The accuracy of the Support Vector Machine is influenced by several factors, including the comparison of the amount of training data and test data adjusted for k-fold validation. In the comparison of training data and test data the resulting accuracy reaches 97.68% with a total composition of 345 training data (50%) and 345 test data (50%). In the tests carried out, the accuracy of Support Vector Machine and Forward Selection was obtained at 97.68%.

Abstract

K-Means and Fuzzy C-Means Clustering is a method of analyzing data that performs the modeling process without supervision (without supervision) and is a method that groups data by partitioning the system. Clusters Clusters and Fuzzy C-Means will produce different clusters in the same dataset, cluster validity index is a method that can be used to improve the results of clustering generated by the clustering method. This study will use the cluster validity index on the kmeans clustering algorithm and Fuzzy C-Means by calculating the index of validity of each kmeans clustering result with k = 2, ..., kmax (k max determined at the beginning) and the results from Fuzzy C-Means with c = 2, ...., cmax (c max is specified at the beginning). By using the cluster validity index, the most optimal cluster is obtained in the second cluster with the Dbi value = 0.45 in the mean K and the second cluster with the Dbi value = 0.5 in the Fuzzy C Mean, and the results of the clustering are consistent.

Abstract

Software-Defined Network (SDN) is a new concept used to solve network problems by separating the control plane and data plane in a different device. Communication between the control plane and the data plane uses the Openflow scenario. SDN has several capabilities in many network technology methods and has been implemented, among others, for routing mechanisms. In routing, there are several problems including failure path. When a fail path occurs, the system will look for another shortest path using the Floyd-Warshall algorithm. The Floyd-war shall algorithm will be implemented using the POX controller. The implementation uses a mesh topology on the mininet emulator and pox as a controller. This research method includes analysis consisting of the preparation of hardware and software requirements, and analysis of how the system works, a design consisting of mesh topology, Floyd-war shall algorithm flowchart, propagation testing, throughput, and latency testing, implementation consisting of operating system installation, Mininet, POX, Applying Mesh topology to the Mininet Emulator, and Applying the Floyd-war shall Algorithm to the POX Controller, manually calculating the Floyd-Warshall algorithm on the mesh topology and testing which consists of testing propagation, throughput, and latency. Furthermore, testing with 3 tests is propagation, throughput, and latency. In testing the throughput and latency there are 3 scenarios.

Abstract

Increasing requests for client connections to servers on a network can cause a problem with server performance to decrease and too many user requests make the workload on the server increase rapidly resulting in the server being down, so we need technology that handles complex network usage. Then it can be solved with a load balancing system. Several studies on load balancing on haproxy and router OS with various algorithms applied will produce different performance, including round robin, least connections, and source algorithms on haproxy load balancing, while NTH, PCC, and ECMP on load balancing routers OS. Testing is done with 3 scenarios, scenario 1 with a load of 10 users, scenario 2 with a load of 20 users, and scenario 3 with a load of 30 users. The test parameters used are throughput, delay, and jitter using the webserver stress tool and wireshark. The results of the performance measurement of the load balancing method on haproxy generally show that the least connection is better than the round robin and source methods, this can be seen from the measurement figures for delay and jitter parameters that are best found in the loast connection method. While the results of the performance measurement of the load balancing method on the OS router, there are two, one shows that PCC is better, this can be seen from the measurement numbers of the delay and jitter parameters, then the second shows that the ECMP method is better, this can be seen from the throughput parameter measurement figures and delay.

Abstract

The building is a place to hold an event with a large number of visitors. The use of the building in holding an event makes it easier for event organizers in the process of implementing the event. The current building rental system at the Kemuning building hall takes a long time in the process of renting the building. The search for information and the process of listing the status of building leasing still uses a manual system, which is recorded in a rental book. This can make the building rental system unstructured and poorly controlled. An information system can make it easier for tenants in the rental process for the yellow building. The building rental information system application uses the web engineering method which aims to build an integrated information system that can engineer the web with several technical requirements and identify information. The resulting information system is a building rental website that can minimize errors made by officers in registering tenants, data building rental recapitulation, avoiding data manipulation and being a distinct advantage for managers who prioritize technological advances by using the system through website-based database applications. The features on this website include a list of packages offered, the ease of making building rental reservations and making the payment process easier. This building rental information system can provide convenience for consumers and officers in the process of renting a building and managing data on the rental of the Kemuning building.
