<![CDATA[The problem of emphasis on the cost of spending on the need for ordering within a company is very complex where the company demands a very optimal achievement that will lead to a huge profit for the company. Gundaling Farm is a company engaged in the business of producing and selling cow's milk is always trying as much as possible to meet customer demand. In this research used Economic Order Quantity (EOQ) method with a genetic algorithm to solve supply problem on Pt.Gundaling Farm. This research is expected to help PT.Gundaling Farm to consider and determine the policy in inventory control activities in order to run more effectively and efficiently. EOQ is the quantity of goods that can be obtained with a minimal cost, or often said to be the optimal amount of purchases. So by applying EOQ method, PT.Gundaling Farm will know how many order (quantity order) goods and when PT.Gundaling Farm should re-order goods during the period 2015. Thus PT.Gundaling Farm can optimize the cost of inventory to be spent on goods.Keywords: inventory, goods, Economic Order Quantity (EOQ).algorithm, genetic]]>

<![CDATA[Paragraph consists of sentences which has main idea. In this research, it applied the genetic algorithm to recognize a paragraph. It has several steps to do it, firstly on the alphabet forms word, then sentence, and finally paragraph. The process start from typing the paragraph and then the genetic algorithm will identify the paragraph accordingly by stages which are initial population, selection, crossover and mutation. Genetic algorithm is heuristic searching algorithm which based on nature selection of mechanism and nature genetics. Paragraph is a set of words or other characters with one or more languages are written especially if arranged in a customary order. The final result of this research is that showing the exact paragraph that is targeted.]]>

<![CDATA[Gold is one of the people's preferred forms of investment and is considered the safest (save -heaven). Gold risk which is considered small is the main attraction because in general Indonesian people are not yet familiar with capital market investments such as stocks and mutual funds. But the price of gold is very volatile as for the factors that affect the fluctuations of gold are consumption demand, volatility and market uncertainty, protection of low-interest rates, and the US dollar. Predicting the movement of the gold price and knowing where the direction of the exchange rate moves and determining the price of gold up or down cannot be done accurately and consistently. For this reason, in reducing the risk of loss, an application is needed to predict gold prices using the Fuzzy Time Series Chen algorithm using MATLAB software. In this study to obtain prediction results and comparison charts using actual data and prediction data for the 2015-2017 gold price. From the calculation results obtained by the prediction results with the Fuzzy Time Series method with the Chen algorithm where the average difference between the actual data and prediction data is not more than Rp. 2,850, - where predictions using the Fuzzy Time Series method Chen's algorithm is sufficient to use 1 data to predict the second data which makes this method accurate in predicting the price of gold.]]>

<![CDATA[Segmentasi citra tenun merupakan langkah yang dilakukan untuk memisahkan bagian area objek (foreground) dengan latar belakang (background) pada citra tenun, sehinggah objek tenun yang tersegmentasi berupa motif dapat diproses untuk keperluan lain seperti pengenalan pola. Hasil dari segmentasi harus akurat, jika tidak akurat dalam memisahkan objek yang ada pada citra maka akan mempengaruhi hasil proses selanjutnya. Pada penilitian ini segmentasi dilakukan menggunakan metode Otsu Thresholding pada citra tenun timor dengan terlebih dahulu melakukan preprocessing yaitu reduksi noise menggunakan Median Filter. Setelah mendapatkan citra hasil segmentasi menggunakan Otsu Thresholding dengan Median Filter, selanjutnya melakukan pengukuran performa, hasil segmentasi dari setiap pengujian dievaluasi dengan menggunakan RAE (relative foreground area error) dan ME (missclassification error). Terdapat dua skenario yang diimplementasikan dalam melakukan segmentasi citra tenun timor, skenario yang pertama yaitu melakukan segmentasi citra tenun timor dengan menggunakan metode Otsu Thresholding dan skenario kedua melakukan segmentasi citra tenun timor menggunakan metode Otsu Thresholding dengan penambahan Median Filter. Hasil segmentasi dari 16 citra tenun timor dari 8 motif yang ada menunjukkan bahwa, segmentasi citra tenun dengan menggunakan metode Otsu Thresholding dengan menambahkan Median Filter mendapatkan nilai rata-rata RAE terbaik yaitu 0.34 % dan nilai rata-rata ME sebesar 0.55 %.]]>

<![CDATA[The COVID-19 emergency period changed the education system in Indonesia in a very short time, requiring every student to study remotely. Of course this encourages teachers to innovate and policy makers in this case the Ministry of Education and Culture of the Republic of Indonesia to make adjustments during the COVID-19 pandemic by changing some rules by issuing circular letter number 2 of 2020 regarding the prevention and handling of COVID-19 in the environment. Ministry of Education and Culture, as well as circular letter number 3 of 2020 regarding the prevention of COVID-19 in education units. The readiness of schools in implementing distance learning received various positive and negative responses from various elements of society. The readiness of teachers in the implementation of online education has not been maximized, this is due to the lack of knowledge in the field of Information Technology. Therefore, to support government policies in implementing distance learning and minimizing the spread of the COVID-19 virus, teachers need to be equipped with e-learning implementation. Teachers are expected to be able to compile learning materials using online e-learning using the Edmodo platform so that teachers are not only fixated on one learning model using conventional models]]>

<![CDATA[In a distributor company, stock is one of the important factors that need to be considered by the company. The amount of stock in and out must be considered, the aim is to keep the stock available stable. A stable stock means that in a warehouse there is no excess stock or lack of stock. The problem is that each item has a different buying interest. Then a calculation is needed to be able to predict what items need to be added or reduced in the warehouse. C4.5 algorithm is a group of algorithms using decision trees. Decision trees are a very strong and well-known method of classification and prediction. The richer the information or knowledge contained by training data, the accuracy will increase. This algorithm is used to analyze the time of purchase of goods that have been depleted by classifying the items which are already in stock added or not, so that the availability of goods keep stable. The application of the C 4.5 algorithm can be used to predict stock availability at CV Harapan Raya. The results of calculating the entropy value in algorithm C 4.5 can predict the amount of stock provided by CV Harapan Raya.]]>
