Sorting is a stage carried out by fish farmers during the harvesting process. So it is a tool that can help farmers do sorting during the harvest process. Automatic fish sorting tool with Sugeno Fuzzy logic based on a microcontroller is one solution to assist farmers in sorting. With this system we can reduce errors that often occur in the manual sorting process. The main cause of the manual sorting process is that many fish do not match market needs. This system is only used for the process of harvesting catfish for consumption. There are three classifications of weight categories on these tools including small, adequate and large, in the range of values 0-120g, moderately in the range of values of 121-200g and large in the range of values of 201-1000g. This study uses the Sugeno Fuzzy logic method because this method is suitable for use in most real-time problems such as making decisions to find things that are volatile and less certain. In this system there is a microcontroller that has been implanted with Sugeno Fuzzy logic. The sorting process is carried out using a Load Cell sensor as a fish weight counter and assisted by servo movement and the sorting results will be displayed on a 4x20 LCD.

The accumulation of transaction data on the sale of building tools and materials, which is increasing day by day, should be used as information that can support sales in stores. Consumer purchasing patterns are the main source of data processing. In this study, it is necessary to have a system to process the transaction data based on trends that appear simultaneously in one transaction. The data used is 1000 sales data from December 2020 to May 2021 by calculating the minimum value of support and minimum confidence as a benchmark in the apriori algorithm process, results obtained are in the form of output which is an association rule that will be used by the store. Input the data in the application after that obtain results item set combination. After that these are obtained by calculating the minimum support. The results obtained are processed again with minimum confidence then the results are being final results of association rules that can be used by stores. If the minimum support is 0.1 (10%) and the minimum confidence is 0.5 (50%), then 122 association rules are obtained, one of which is in the 100th order, "If a customer buys a VSB Board, the customer also buys Jumbo Furing with a support value of 23, 3% and a confidence value of 82.9%”. Association rules as the final result are to evaluate, carry out sales strategies, alternative decisions in stocking goods and determine the placement of goods close together.

The development of this very advanced technology in computers era, all document have turned into softcopy file, which can be accessed with computer or smartphone. So many people commit plagiarism by not listed the source and resulting copyright infringement. The plagiarism can be interpreted as an action that takes statements of theft other people’s ideas. In law, patents and intellectual property rights are already regulated In law. Therefore to make it easier for teachers and lecturers in academic. Identification of document is needed to know whether the document includes plagiarism by detecting the similarity of text between documents. Then the authenticity in each document can be maintained its authenticity. The process of identification are using Winnowing and Ratcliff/Obershelp algorithm. Winnowing algorithm is algorithm used to perform the process of checking word similarity (document fingerprint) to identify plagiarism of document. Ratcliff/Obershelp is also used to detect similarities, but it works by returning value that can be userd as a percentage to show the similarity of two strings by calculating the number of characters contained in two strings. Both of these algorithm can be used to identify percentage of similarity of text document.

In order to make it easier for white shrimp (Litopenaeus vannamei) farmers to monitor pond water quality so as not to disrupt the growth process of white shrimp, a system was built that can be used to monitor and control pH and water temperature conditions remotely using pH sensors and temperature sensors based on IoT. Internet of Things or IoT is a technology that uses the internet to carry out a process of sending data to several devices without using the help of computers and humans. In this case the research was carried out using two water quality parameters, namely water temperature and pH level. This control uses two actuators, namely a water wheel which is useful for lowering the water temperature and a water pump for adding water with the aim of increasing or decreasing the pH level using the fuzzy Sugeno method. The results of the error presentation on the pH sensor were 0.002% and the precision behavior (accuracy) on the pH sensor circuit was 99.998%, the error presentation results on the temperature sensor were 0.038% and the precision behavior (accuracy) on the temperature sensor circuit was 99.962%. carried out by researchers, it can be concluded that the fuzzy sugeno method can fulfill the purpose of monitoring the pH and water temperature of Litopenaeus vannamei shrimp pond water based on IoT, by using 3 temperature rules, namely low temperature: 0-26, normal temperature: 27-30, high temperature: 31 - 45 and 3 rule pH, namely acid: 0 -7.4, normal: 7.5-8.5, alkaline: 8.6 – 14.

Diabetes mellitus is a chronic disease characterized by high levels of glucose (sugar) in the blood that is high for a long period of time. Identification is the process of recognizing and determining the characteristics of a particular object or entity. hypertension (high blood pressure), smoking and lack of physical activity can affect the condition of diabetes mellitus patients. Therefore, an approach is needed that can identify groups of diabetic patients based on their risk factors, so that appropriate management and treatment can be carried out. The purpose of this study is to apply PCA method by reducing data dimension to identify the linear combination of the most contributing risk factors in diabetes mellitus patient data and apply K-Means Clustering to cluster into groups based on similar risk factors. The methods to be used are Principal Component Analysis (PCA) and K-Means Clustering. type of quantitative research, this research can be categorized as analytic research, variables are risk factors for diabetes mellitus disease. The results of research using the PCA (principal component analysis) method obtained 9 main components (PC) 86.9275%. correlation between attributes and principal components, then a matrix component is formed with a loading value that the greater the value, the stronger the correlation with the principal component formed with a cut off point of loading value> 0.4 regardless of positive and negative. By using the K-Means Clustering method, The clustering results obtained are divided into 3 groups of diabetes patients based on existing risk factors. Centroid C1 represents a group of diabetes mellitus patients whose condition is at a mild level, while Centroid C2 represents a group of diabetes mellitus patients who are at a moderate level, and Centroid C3 represents a group of patients with severe or dangerous diabetes mellitus.
