Abstract

In a business of laying hens farm, the feed costs constitute as much as 60-70 percent of the total cost of livestock production. Breeders can compose rations for their laying hens independently to save the feed costs. However, in the making of rations, breeders must examine the nutrient content and price of each feed ingredient that will be combined first. Breeders also have to evaluate manually whether the ration formula that will be given can fulfill the nutritional needs of laying hens. Therefore, to improve the efficiency of feeding in accordance with the nutritional needs of laying hens and with minimum cost, this study designed a system to determine the optimal layer feed composition using Improved Particle Swarm Optimization (IPSO) algorithm, an optimization technique which is a development of the PSO algorithm. Particles move in search space to find solutions. From the test results obtained optimal values for each IPSO's parameter, population size = 250, maximum iteration = 350, and the interval of feed ingredient weight = 1-70%. IPSO algorithm is able to give solution of feed composition with cost 50.41% cheaper than one of the data from laying hens breeder.

Abstract

Indonesia is an agricultural country which has many agricultural commodities such as spices demanded by foreign countries and has a high trade value. Currently, the production and export of Indonesian spices no longer dominate the global market, Indonesia has lost its glory in the world spices trade. It is caused by many farmers who only use limited experience and knowledge to fertilize the spices which can lead to crop failure and a big loss. Based on these problems, I will design an intelligent system that can optimize the fertilization in agricultural spices so the farmers could get optimal fertilizer for agricultural spices by using Genetic Algorithms. Genetic Algorithms was chosen because this algorithm can be used in problem optimization in a wide search space quickly. Test result using 2 type of plant, 3 types of fertilizers, 100 population size, 700 total generation, 0.3 cr and 0.7 mr combination can meet the nutrient needs of plants. The best result of this system testing can save cost of 0.23%.

Abstract

One way of the good maintenance to laying chickens is separate the healthy and unhealthy chicken in defference cage quickly and correctly. But, in reality there's so many stock farmer who don't have fast response about the issue. Other than that, in the rural area we couldn't find any veterinarian or farm expert easily. So, we need a system to identify the condition of chicken health automatically. In this case, clinical symptoms in sick laying chickens can be observed through changes in color brightnes and texture in the wattle. Healthy laying chicken has bright red wattle and it tends to feel rough. The solution that can be applied to this problem is image processing with HSV color and graylevel coocurence matrix (GLCM) feature extraction. In this study GLCM method oriented by 4 angles that are 00, 450,900 and 1350 with d=1. From the extraction results we will get the values of HSV and statistic feature of GLCM such as entropy, energy, homogeneity, contrast and correlation for K-NN classification's input. A total of 26 testing data features will be calculated its euclidean distance with training data to search classes from input data. Based on the result of this study, the best accuracy obtained when classification with (GLCM 4 directions or 00) + all component of HSV and the number K = 3, K = 11 or K = 15 that is 100% correctness.

Abstract

The problem of the utilization of raw materials in the furniture industry is the difficulty of cutting raw materials with the right combination of sizes. To adjust the furniture production requirements, standard-sized raw materials must be cut to fit the needs of the furniture model to be produced. If not done the exact calculation when cutting the raw materials will certainly produce a lot of waste materials unused. The abundance of unused raw materials is what causes the maximum profit can not be achieved so that optimization of the remaining raw materials needs to be done. In this research optimization of the remaining raw materials is done with Genetic AlgorithmCorner Junction (GA+CJ). Stages performed are initial population generation, mutation with Rectangle &Junction Gene Swap Mutation(RJGSM) and Rectangle Rotation Mutation(RRM), evaluation, and selection. The results obtained in the form of chromosome-shaped solution arrangement of pieces of material. The highest fitness is 0.0026 which means consuming 16 pieces of raw material located on generation input parameter as much as 120 generations, mutation rate equal to 0.9, and 60 populations.

Abstract

The amount of vehicles in Indonesia increases every year, this causing long queues at gates, mall, or tolls that require the process of recording license plates. This research will help simplify the process of recording license plate by creating a vehicle license plate recognition system. The system will try to recognize the license plate from a digital image. The first step in the license plate recognition system is to detect the location of the license plate by applying vertical edge detection because the area of license plate contains rich edge and texture information. The next step is character segmentation, this is a process to get characters from license plate image. this can be done by applying connected component algorithm. The last step is character recognition using learning vector quantization algorithm. Based on the result of this research, the highest accuracy is 94% in the license plate detection process, the highest f-measure value is 0,88 in the character segmentation process and the highest accuracy for character recognition using Learning Vector Quantization algorithm is 86,67%.

Abstract

Equity in the distribution of subsidized fertilizer has several constraints. Based on a survey of equal distribution of seed and fertilizer subsidy at farmer group of Pandansari Village of Kediri Regency, several equality obstacles are that most farmers have no basis and proper calculation in buying fertilizer subsidy based on nutrition requirement of planted seeds. So that resulted in farmers only buy the type of fertilizer with the same composition when different plant varieties that cause less than maximum yield. Besides also if the composition of fertilizer not in accordance with the varieties then the amount of fertilizer in the warehouse will be shortages and excess. To solve the problem used Genetic Algorithm method. The algorithm parameters used in rice plants are population as much as 220, generation as much as 1100, crossover rate 0,8 and mutation rate 0,2 whereas in corn plant population as much as 320, generation 1250, crossover rate 0,8 and crossover rate 0 , 2. The average percentage difference in value generated by genetic algorithm and fertilizer in warehouses on rice plant is 9,873% while in corn plants yield difference of mean percentage between fertilizer in warehouse and genetic algorithm equal to 24,882%. Solution The composition of fertilizers produced by genetic algorithms can be ascertained that the nutrients needed by plants are met so that the yield can increase.
