Abstract

Identification of citrus maturity is still done manually by the farmers. Fruit seen visually by eyes and responded by the brain to differentiate maturity level. In large amounts it would be difficult to maintain its performance. This study was a non-conventional method of measurement that used digital image processing to produce data that will be processed by artificial neural network and then processed using computer software that can be used to determine citrus maturity level. Citrus are identified based on the histrogram input image color ( RGB ) that obtained from the results of the capture program built by using Visual Basic. Some sample of the learning pattern citrus data had different weighted values as input to the neural network by using back propagation method to distinguish raw, ripe and over ripe fruits. This identification system was capable to identify the entire category of fruit which were 90 % correct identification. From the identification that had been done, resulting the identification of the three outputs 100 % ripe citrus, over ripe 80 %, and 100 % raw. Results of the identifications were affected by the shooting fruit process. Key words : Artificial Neural Network, Image processing, back propagation, Identification, citrus

Abstract

The processing of food preservation to increase food (fish) storage abilityis interested to be known. One kind of the preservation is by drying. This research aimed to design, make, test and analyze cabinet dryer economyc value. Parameters observed were fish moisture contents, equipment capacity, and economic analysis. It was found from the research that fish moisture contents after dryin (dry base) was 38,69%. Capacity of the cabinet dryer was 0,92 kg/hour. Economic analysis, main cost to dry 1 kg fish was Rp. 6.285,4. Break event point (BEP) was 381,49 kg/year. Internal rate of return (IRR) was 59,77%. Keywords : Pora-pora fish (mystacoleucus padangensis), fish drying , cabinet dryer.

Abstract

Seat is one of the dominant factors to get a job perform conveniently on a four-wheel tractor by operator. It is therefore necessary to design a seat that fits the dimensions of Indonesian’s body in general, as the tractor in Indonesia is made overseas. This research was conducted by measuring the dimensions of the body 100 correspondents that were taken randomly. The data collected were popliteal height, buttock-distance popliteal height, shoulder span, span between the elbow rest position, high elbow resting position, the shoulder height and weight. The results showed that high current cushion was 50 cm high while the proposed was 46 cm. The current length of the cushion was 38.5 cm while the proposed was 46 cm, width of the cushion was currently was 46.5 cm while the proposed was 38.4 cm, high backrest c current was 47.5 cm while the proposed was 23 cm and the proposed was load 60-70 kg. Keywords: tractor, anthropometry, seat

Abstract

On direct steam destilation type, destillation temperature needs to be considered. The temperature determines the quality of destilation product. This study tested various temperature on destillation of volatile oil in direct steam type destilation. The study was conducted at the Laboratory of Agricultural Engineering and analysis was done in Food Chemical Analysis Laboratorium Faculty of Agricultural in September 2014 to October 2014 A non-factorial completely randomized design with 95°C, 100°C and 105°C was used. Parameters measured were water content, free fatty acid and yield. The results showed that the temperature had  significant effect on yield. The best treatment was the U3 treatment (105°C) which produced 21,1% water content, and 0,44% yield. Key word: Destillation temperature, direct steam, patchouli oil

Abstract

In general, soybean epidermis peeler bring out soybean seeds along with the epidermis so it must be separated manually. Improvement is necessary to solve the problem. One of the alternatives is to modify the peeler by adding blower. With the addition of the blower, the soybean seeds and the epidermis brought out separately so that the peeler work capacity can be improved. Soybean epidermis peeler with blower was designed to peel the epidermis in the dry state. Blower in this peeler was centrifugal blower with 150 Watts of power, 3000 rpms of speed, and 2 inches diameter of the output hole. Effective capacity of the modified soybean epidermis peeler with blower in this study was divided into three different rate was blower with maximum rate was 54,64 kg/h; blower with medium rate was 43,48 kg/h; and blower with minimum rate was 52,63 kg/h. Keywords : blower, Soybean peeler, work capacity

Abstract

Soybean peeling is aimed to simplify the processing of soybean in the next step, such as in tofu making, tempe making and soybean extract. The peeling techniques of soybean was used widely with simple way which is soaked in the water and stomp it in a basin until its skin peeled. This research was to design,  make, test and analyze the economic value of the soybean peeler. The parameters of this research were effective capacity, broken peeled soybean percentage, unpeeled soybean percentage, losses soybean percentage and economic analysis. The results showed the effective capacity was 55,5 kg/hour. Percentage of broken peeled soybean was 4,91%, percentage unpeeled soybean was 11,01% and percentage of losses soybean was 2,1%. Economic Analysis was Rp. 104,373/kg, BEP was 259,32 kg/year and IRR was 66,54%. Key words : epidermis, peeler, silinder type, soybean
