Many farmers are interested in planting chrysanthemums because of its beautiful colors. The allocation of land resources, raw materials, machinery, capital and labor which is now done by farmers, is relatively not able to meet the desired target. It demonstrates that the use of resources is not optimal and it will have an impact on the level of benefits received. The result of the data processing was: the Chrysanthemum production rate, based on the optimization results, illustrated that the recommended type of chrysanthemum to be produced was only the standard type, because it increased the revenue for companies. Company A produced 486.11 bunches of chrysanthemum for Rp 1,701,389 per growing season, company B produced 277.77 bunches for Rp 972,222 per growing season, company C produced 150 bunches for Rp 450,000 per growing season, and company D produced 250 bunches for Rp 750,000 per growing season. The resource or factor of production that was totally applied on the optimum condition was the green house land resources, which is a limiting resource; but other resources was excessive or not a limiting resource. The usage or availability of limiting resource could be improved to increase the profit of the company. The environmental changes can affect the company's revenue, to see how big the changes which didn’t change the optimal conditions were. It was generated by looking at the results of the sensitivity analysis. Sensitivity analysis of the objective coefficient value which was obtained for the standard type of chrysanthemum, the allowed increase in gross profit was infinity, while the allowed decrease in gross profit was when it approached the value of the gross profit.Keyword: chrysanthemum, primal analysis, dual analysis, sensitivity analysis

New born babies have the ability to express their basic needs through sounds. A system to understand the meaning of crying infants of aged 0-3 months is called Dunstan Baby Language (DBL), which was introduced in 2006. This research aimed to perform the modeling of codebook method with k-means clustering technique as feature matching, and Mel Frequency Cepstrum Coefficients (MFCC) as feature extraction to identify the infant cries. The infant cries identification of Dunstan Baby Language version used the shortest distance of mahalanobis. The treatment in this research was the combination of frame length: 25 ms, 40 ms and 60 ms, frame overlap of 0%, 40%, and 60%, and the number of codewords (number of clusters) of 1 to 29. The best accuracy in recognizing five types of crying Infants using mahalanobis distance can be achieved up to 83% when the frame length = 275, the overlap frame = 0.25, and the k = 17. Sound ‘heh’ was the most familiar, whereas sound ‘owh’ was always missunderstood and generally known as ‘neh’ and ‘eairh’.Keywords: Codebook, Dunstan baby language, Mahalanobis Distance, MFCC

Crossbreeding between species (hybridization) was conducted to obtain higher average value of offspring trait than the parent trait. The aim of this study was to determine the best type of mule duck and to evaluate the heterosis effect appearing on mule duck obtained. The experimental design used was a randomized block design with two levels of treatment and eight groups based on the hatching period. The treatments were the type of mule duck crossed between muscovy duck male with female cihateup duck (EC) and mule duck crossed between male muscovy duck with female alabio duck (EA). The results showed the growth performance and carcass production of EC and EA mule duck were not significantly different, but mule duck EC tended to show better results than mule duck EA. The percentage of heterosis effect produced by EC and EA mule duck in growth performance and carcass production showed advantages over the parent. EC mule duck had a higher level of heterosis than EA mule duck for some trait observed. EC mule duck can be kept as best crossbreed to produce mule duck with good performance and carcass production.Keywords: mule duck, performance, carcass production, heterosis
