Abstract

Observation of the weather elements is very necessary for the welfare of mankind, the weather elements that are observed will be used as material to predict the weather in the future. Weather data can also be used to reduce the risk of adverse effects caused by the weather itself. To measure the weather with an automated monitoring system that is cheaper and of good quality, AWS was created. The AWS design using Raspberry Pi was made as a use of Raspberry Pi mini computer technology for the purposes of the Meteorology, Climatology and Geophysics Agency (BMKG). humidity, Rain Counter, wind direction, wind speed, air pressure, altitude, and GPS. Display data can be monitored via the web in the form of an Analog Gauge.

Abstract

One of the foods in Indonesia that has a lot of nutritional content and benefits, one of which is tempeh. Tempe is usually made by fermenting soybeans with mold under special conditions to become tempeh. In the fermentation process, tempeh producers need to monitor the maturity of the tempeh until it is suitable for consumption. To detect this maturity requires a separate effort, so that an image processing approach is proposed in this study with the support of feature selection. An image allows for various features to be taken, such as texture features using GLCM and various color features including RGB, HSV, LAB, CMYK, YUV, HCL, HIS, LCH. With so many features, it is necessary to do a selection so that computation in its classification becomes efficient. This study aims to classify tempeh fermented images using the Naive Bayes method with Linear Discriminant Analysis (LDA)feature selection for GLCM features and eight color features. Tempe fermentation image is divided into three classes, namely raw, ripe and rotten. Based on the experimental results, the average accuracy in the test is 84.06%. In testing the fastest time is 1.87 seconds and the longest is 2.20 seconds. This shows that the classification of fermented tempeh maturity with Naive Bayes with LDA feature selection can work well.
