Abstract

Seaweed is one of the main superior commodities in the City of Tarakan. The problem often faced in the field is that the increase in production is not proportional to the price of seaweed that fluctuates every month from year to year, making it difficult for collectors to determine the price of seaweed for sale. Price increases caused by various factors such as the drying process, long marketing chains, and increasing demand from domestic companies. In determining the price of seaweed in the future some approach is needed to predict or predict the price of seaweed in the following month. Forecasting (forecast) is an activity or business that knows the events that will occur at that time will use historical data. Prediction methods used in this study are Simple Moving Average and Exponential Smoothing, these two methods will be guided to find out the most appropriate method used in predicting. Based on the minimum error value calculated using the values of MAD, MSE, MFE, MAPE and CFE, it is found that the Simple moving average forecasting method is considered the best method that can be used to forecast seaweed prices.

Abstract

Cryptography is one of science that learn about securing a message. Message security is done by randomizing the message (encryption) and returned to it’s original form (description). In this study, the designer of the system first and build an application to secure the message by using the Lipat Algorithm method that aims to secure messages consisting of letters, numbers, or symbols. Applications are designed and built running on Mobile Android. The Lipat Algorithm Method applies a fourfold system in the encryption process and the description of the message to be encrypted and in the description will advance 4 (four) characters forward or backward. Based on testing done the application managed to perform the encryption process and description correctly, ranging from short messages to messages as much as 2305 characters.

Abstract

This research was conducted to improve the application used in the calculation of the sunshine duration. The research that has been done using the opening method for segmentation of the pias card. The error or failure of segmentation is caused by a small burning object of the pias card and or a thin but translucent object, so that the object is partially lost or forms an object's separation area. Based on the error or failure of segmentation in the above research, the research will be done is to develop similar applications by replacing one of the methods  with erosion morphology. The test was carried out with 92 data and the results stated that Erosion with Radius = 3 became the best alternative method in this research with RMSE 3.14.Keyword: segmentation, object, pias card,opening, erosion.

Abstract

Weaning REX rabbits child is one of the keys to success in raising or cultivating rabbits. Unsuitable weaning can result in very high mortality or mortality risks, while weaning for too long results in decreased productivity and the possible marriage of children with rabbit parent. The research done is to design and build the application of decision support system (DSS) with Simple Additive Weighting method (SAW) with 5 criteria as supporting of DSS calculation that are body weight (gram), body length (cm), still breastfeeding or not, already independent for food or not and Gender. The webased DSS application created is tested  by using the calculation system compared with research data. Based on the test of 36 rabbit children which is derived from previous research results obtained showed that the application of the DSS are built 100% the same result.

Abstract

The measurement of the duration of solar irradiation at the climatology station can be done using campbell stokes and pias cards. The aim of this research is to assist the climatology station operator to determine the burn object on the SO-40U (1400-40S) type of pias cards, making it easier to calculate the duration of solar irradiation. This app is designed and built to successfully segmentation the burn on the card automatically. In this research, the data was collected at a climatology station located in Barongan, Sumberagung Jetis, Bantul. Based on the test conducted segmentation generated in this study is good and produce RMSE number of object result of segmentation equal to 2,6485 to sum object in original image. The difference in object calculation results from a segmentation error caused by a small burning object of the pias card and or a thin but translucent object, so that the object is partially lost or forms an objects separation area.

Abstract

Solar radiation measurements in climatology station barongan done by using campbell stokes and record card. Solar radiation is the accumulation of the whole length of the object radiation recorded on the record card. Solar radiation data reading performed by observers by estimating the long of object irradiation compared with the scale of hours listed on the record card. The difficulties encountered by observers in conducting solar radiation data readout is the shape of the object radiation recorded on the record card are not always in the form of elongated areas, some areas disjointed, even can only form small holes along the track on the card record. The purpose of this study was to design and build a system that can be used to calculate solar radiation recorded on the card record, thus increasing the accuracy of measurement data readout. Cropping process is carried out in order to obtain the right area for analysis. The approach method in object segmentation is done by implementing a solar radiation threshold otsu method. The test results showed that the determination o f the radius o f the opening and removing noise value appropriately irradiation can obtain the number o f objects on test images with RMSEof1.4429 compared with the amount o f exposure o f the image o f the original object. Results o f calculation solar radiation by the system showed system RMSE o f 0,51 to observer calculation.
