Abstract

Pestisida merupakan zat atau bahan kimia yang digunakan unuk membunuh hama pada tanaman yang dapat menghambat pertumbuhan tanaman sehingga berdampak pada hasil panen yang kurang baik. Toko Dewi Sri merupakan salah satu toko obat pertanian yang ada di Desa Beru Kecamatan Sarirejo yang menyediakan berbagai macam obat-obat pertanian yang dibutuhkan oleh para petani di Desa Beru Kecamaan Sarirejo. Adapun tujuan dari penelitian ini adalah untuk memprediksi penjualan obat pertanian. Dimana metode ini bekerja dengan membentuk suatu pohon keputusan. Berdasarkan hasil perhitungan yang telah dilakukan didapatkan hasil Akurasi sebesar 75%.

Abstract

identification or classification using image processing and computer vision requires pattern recognition from the training dataset. The process of image processing and pattern recognition becomes a highly developed research study. Starting from the process of recognizing an object, or classification of objects and about detecting the level of fruit maturity. This research will classify the level of maturity of mangoes with HSV images. Where the RGB input image is converted to HSV. Then the average values of HSV intensity, skewness, and kurtosis are taken. The process of classification comes into 4 classes: raw, fairly ripe, ripe and very ripe. With the KNN classification method, and the dataset used 129 training data, and 40 testing data. The highest accuracy value at k = 2 is 80%. The tool used to develop the system is matlab.

Abstract

In the world of engineering, one example of using a matrix is to find a solution to a system of linear equations (SLE). In the scientific field that studies electrical circuits, it is not uncommon to use matrices to calculate the quantities or values in an electric circuit. To make it easier to find these values, an operation process based on the Cramer and inverse methods based on Matlab is used so that finally the values contained in the electrical circuit are obtained. These values are electric current and electric voltage. In this study, it can be concluded that the use of the Matlab-based matrix inverse method is better in terms of the accuracy of the research results, when compared to the manual use of the Cramer method, which has an accuracy difference of 0.0006%. For the calculation of the current variable i3. and 0.81% for the calculation of the electric voltage variable at node AB.
