Abstract

One of the requirements for good quality tobacco is a good land use. Improved quality of the land will result in increased quality and quantity of tobacco plants produced. The main constraints experienced by tobacco farmers in determining land suitability are the limited knowledge and difficulty of obtaining correct data on the quality of land suitable for tobacco plants. Therefore, a computerized system is needed to assist farmers in making decisions on prospective land to be used. This system is implemented using Fuzzy Inference System (FIS) Mamdani and optimized using Genetic Algorithm. Some of the factors used in this system include the percentage of land affected by the disease, the openness of the region, the degree of weight of the soil, the thickness of the layer, the ease of irrigation, terrain conditions, and soil pH. The reproduction method used is extended intermediate crossover and random mutation, while the selection method used is elitism. Based on the results of the tests that have been done, the most optimum solution obtained on the total number for 90 population , the combination of cr and mr value of 0.2 and 0.8 respectively and the number of generations of 500, with the average of fitness value generated of 0,917. The Accuracy generated by this system is 80 % using 10 test data.

Abstract

Palm oil is a plantation product that is the main export commodity of Indonesia. The increasing amount of processed materials that can be made by using palm oil makes the rise of oil palm demand. The main factor causing an increase in demand for palm oil is a relatively low price compared to its competitor prices such as soybean oil, sunflower seed oil, peanut oil, cotton oil and rapeseed oil. Price becomes an important factor to determine the selling point of the product. Prices also affect the producer's profit. The classification of the possibility of rising or falling prices of palm oil becomes a major consideration of a consumer to buy. This writing discusses the classification of palm oil prices using Backpropagation method. The Backpropagation method will model the coconut oil price data 5 months earlier to find the classification results in the 6th month. Classification results obtained have an accuracy of 69.57% with the number of hidden neurons as much as 50, the value of learning rate as big as 0.1 and the number of maximum iterations of 70,000.

Abstract

The vascular changes that occur in retinal are precursors of a diseases, such as heart disease, diabetic retinopathy, stroke and hypertension. Changes can be seen by analyzing retinal image, but it takes a long time. In this study we propose the automation of vascular segmentation processes in retinal image so that can assist in analysis process, which is an important step in retinal image analysis. The segmentation process is done by detecting the line using the Multi-Scale Line Operator algorithm and preprocessing image using K-Means algorithm. Line detection is performed on several different scales, then combines the results of each scale. Image preprocessing using the K-Means algorithm aims to ignore the optic disc area, which in that area will probably be detected as false positive. The performance of proposed algorithm was evaluated using the DRIVE and STARE dataset, the result showed that average accuracy of the DRIVE dataset reaches 0,940980219 with AUC 0,7462, and for STARE dataset reaches 0,949293361 with AUC 0,778. The results are obtained by using the number of K as much as 3 on the K-Means algorithm, which consists of background, foreground, and vessel.
