Abstract

Before the credit is given to the prospective debitor, the lender needs to select the prospective debitor's data first by considering several criteria. This is because the creditors get some problems that often occur when giving credit worthiness such as inconsistency to credit analysis that can change and the length of time required to select the data of prospective debitor due to the data that many and varied. These problems can be solved by building a classification system using the fuzzy tsukamoto method to classify the data and determine the creditworthiness of the debitor. However the use of the fuzzy tsukamoto method can not provide optimal results. It is shown with the accuracy value obtained is 90.476% from the test using 63 sample data. To obtain a more optimal accuracy, the workable solution is to optimize the fuzzy membership function constraint using genetic algorithm. Based on the results of testing system that has been optimized, the system obtained accuracy value of 93.651% with parameter popsize 220, Cr 0.7, Mr. 0.3 and generation number 220.

Abstract

Kidney disease can be caused by several factors such as hypertension, uric acid levels, creatinine levels, diabetes, and many others. From that factors, we know about the level of kidney disease risk. Some people are unaware, lazy and indifferent about health, especially on kidney disease because of the long process and complicated. According to the Indonesian Renal Registry, in 2014 patients with kidney disease in Indonesia reach 12,770 inhabitants. Therefore, we need a system that can detect or identify the kidney disease. In this research, we will identify the kidney disease using Neighbor Weighted K-Nearest Neighbor (NWKNN) method. This method is similar to the KNN method but the differentiates are in the weighting process in each identification class. Identification class in this study decided in two part, ckd or exposed to kidney disease and notckd or not affected kidney disease. The results of this study indicate that the NWKNN method can identify kidney disease when the data are 150 data and the test data are 50 data with K = 2 and E = 2 and accuracy level is 88%.

Abstract

Humans are one of the living beings that exist in the world. One of the important organs that exist in humans are the ears, nose, and throat. This causes the organs to be connected to each other and can cause the spread of infection if one of the three organs are infected. Diseases that attack ENT is still considered trivial by the community, so the public awareness to check to the doctor is still low. Therefore, to facilitate the community to making their own diagnosis of ENT disease, then made a diagnosis system ENT disease. This diagnostic system uses Fuzzy-K nearest neighbor method. The used of the Fuzzy-K nearest neighbor method occurs in some studies that using this method can get high scores. In this study using four pieces of testing, namely testing of variations in the amount of training data, testing of variations in the number of values ​​k., testing of comparison between the number data training and data testing, and cross validation testing. Based on four types of test scenarios performed using 122 data related to ENT disease, obtained results with an average rate of 99,2%.

Abstract

The imbalance between the nutritional intake of pregnant women to meet the needs and energy expenditure must always be monitored, because the imbalance itself can result in Chronic Energy Deficiency both in mother and fetus in the womb. Therefore it needs an appropriate food composition to meet the nutrients and energy for pregnant women, so it can help them to determine their own food. The problem of food composition for pregnant women can be solved by hybrid genetic algorithm and Simulated Annealing. The purpose of combining this method is to produce a better solution than using a genetic algorithm alone. This problem solving process have used crossover method is one-cut point, mutation using reciprocal exchange method, selection using elitsm, and Simulated Annealing.

Abstract

Kenaf plants have many benefits. However, currently it has limitation production of Kenaf palnts. According to Research and Development Agency, Malang City stated that Kenaf seed production was just about 0.3-0.5 tons/ ha, while farmers' need for superior seed of Kenaf plants was about 0.7-1.0 tons/ ha. Balai Penelitian Tanaman Pemanis dan Serat (BALITTAS) Malang city was directly elected to carry out certification of seed consist of field inspection, laboratory test, and labeling. Seed certification aimed to ensure seeds quality. For seeds certification, BALITTAS has difficult to estimate resulted seeds. This estimate was required to prepare certification requirements such as laboratory equipment, yarn, gunny sack, and workers. This can be solved by built an estimation system using backpropagation algorithm. The number of neurons in the input layer was 4 inputs ie the number of seeds production was the age of flower I, bottom diameter, the weight of 10 plants seeds, and the number of mature capsules, and produced 1 output as resulted seeds. The calculation process starts from initialled initial weight with nguyen-widrow, feedforward and backpropagation, then update weight and bias. Test result showed the best mean of MAPE value was 0,938% with 90% testing test scenario, 10% test data, 5 neurons in hidden layer, learning rate 0,3, maximum 1% MAPE and maximum limit of iteration 5000.

Abstract

Palm oil is a plantation that became the number one sector in Indonesia. This plant has a cost and a better production than other plantation crops such as sugar cane and rubber. In a company, palm oil production becomes the driving force of the economy, as well as what happened to PT. Sandabi Indah Lestari. In every week the company plans to predict the production. Planning done sometimes still give less than optimal results. This is because the calculation process is still using manual analysis. In this research will use four prediction features that are plant age, number of trees, land, and production. The prediction technique used is the learning method of Extreme Learning Machine (ELM). This method has advantages in learning speed and accuracy in predicted results. The calculation process starts from the process of data normalization, training a number of training data and test data, calculation of the prediction error value and produce the final value. The data used is production data in the period 2015 - 2017 with a total of 297 data. From a number of data will be divided into two data with percentage of 80% training data and 20% test data. The result of the research was obtained the optimal parameter value that is 13 hidden neuron in testing the number of neurons with Mean Absolute Perscentage (MAPE) value of 21.25%, 20.42% on the data feature test with the best 2 technical features and 20,19% on testing the pattern with the final result of the data pattern 1.
