Abstract

Belle Crown is one of new aesthetic centers in Malang has not applied CRM strategy (Customer Relationship Management) by giving different service for all of its costumers. Segmentation is a process undergo to identify costumers with similar characteristics, therefore, it can help to explore more information on profitable costumers. The costumer's business behaviour could be seen from Recency (last transaction range), Frequency (the number of transactions), and Monetary (the amount of money spent) or it is known as RFM (Recency, Frequency, Monetary). One of data clustering method is K-Means that is used to do the segmentation. The graphics result from Elbow method is used to determine the number of segments intuitively during the application of K-Means method. The data used in this research is transaction history taken from May-October 2017 and it includes 21.513 transactions and 4716 costumers. In its application, the research results two kinds of segments including 2 segments and 3 segments. The analysis based on RFM value showed that the first rate is the profitable customer as it has bigger RFM compared to other segments. The superficial of this research is to produce dashboard visualization as the result of costumers segmentation with some graphics based on RFM value of Belle Crown's service.

Abstract

The interest of Indonesians in having dog as pets is high. Dogs become favorite pets because dogs have funny and adorable habits. In addition, taking care of dogs is quite easy. Prevention and detection of diseases that infect dogs is necessary, so the infected dogs can be taken care of immediately to prevent transmission of the disease to other dogs and to human. Diagnosing the diseases could be a bit difficult sometimes because some diseases have similar symptoms. Another problem is that there are not many veterinary clinics that open for 24 hours so it would be difficult for dog owners if they found out that their dog was sick outside of the clinics' working hours. The system of dog diseases diagnosis is made to assist veterinarians in diagnosing dog diseases, in addition the system is expected to assist the community in making an initial diagnosis of their dogs. This system is Android-based and applies the method of Naive Bayes and Certainty Factor. The Naive Bayes method is used to classify dog diseases based on the usual pattern of symptoms, while the Certainty Factor method is used to determine the value of certainty of classification results from the Naive Bayes method. Based on the accuracy test that was done for five times, the average accuracy value obtained was 97.2%.

Abstract

Diabetes Mellitus is one of the diseases with the highest number of casualties in Indonesia. The high diabetics in Indonesia are due to the lack of public knowledge about healthy food controls that result in poor diet. As a result, many people have not met the balance of nutritional intake that is the most important part in managing a good and healthy diet. Information on the right diet is needed for diabetics to improve their health condition. The Particle Swarm Optimization (PSO) algorithm is often used in performing optimization cases with good and optimal results, in particular, there is development to Improved Particle Swarm Optimization (IPSO) which further improves PSO performance. Therefore, this study designs an optimization system for the composition of food ingredients for the nutritional needs of people with Diabetes Mellitus using Improved-PSO algorithm. The results obtained from this study are optimized Improved-PSO parameters that are population number = 150, acceleration coefficient value = 2, 1, and convergent system on iteration to 550. In addition, from the results of global analysis shows that the nutrient calculation of the system can meet the nutritional needs of patients with a difference of tolerance ± 10% of expert calculations.

Abstract

Rice is very important for human beings, especially to the ASEAN community. Indonesia is one of the ASEAN countries that cultivate rice. In 2015, Indonesia ranked as the third-highest in terms of the world's largest rice producer. However, Indonesia still have to import rice every year due to its high demand and to fulfil Indonesian's per-capita consumption. The other reason is the different amount of harvest on each areas resulting in a scarcity of rice because the country can not be able to optimize the farming techniques that are used. This research use the methods of backpropagation neural network to predict the results of the rice productivity. In its implementation, the data is normalized using the min - max normalization and weighting initialization using Nguyen - Widrow. Based on the results of testing the parameters for the method of backpropagation, shows the most minimum RMSE i.e. 8.6918 with parameter values learning rate = 0.8, hidden layer neurons, hidden = 3 = 4 with the number of epoch 10000 against 135 training and 13 test data. Based on result of 5 fold cross validation against the stability testing data gets an average RMSE of 8.2126.
