Abstract

Pepper plants are agricultural commodities in need in everyday life today, because the plant has many uses. In addition, the chili plant is a plant that was a high economical value. Some of the problems in controlling diseases and pests, among others, are early symptoms that are not clearly visible so that farmers and communities find it difficult to detect the causes of damage that attacks the chilli plants, causing farmers to experience a decrease in crop production and even cause crop failure. The method used in solving this problem is the K-means Algorithm. This K-Means clustering algorithm is a method that attempts to classify existing data into several groups, where data in one group has the same characteristics with each other and has different characteristics from the data in other groups. Chilli data processed in this study was sourced from the working area of ​​the Horticulture and Plantation Food Crops Office of West Sumatra Province with a total of 11 pieces of data. Furthermore, the data is processed using rapidminer studio 7.6 software. The results of the testing of this method there are three grouping causes of damage to plants, namely C0 for chili species with moderate damage, C1 for heavy damage and C2 for mild damage. Then the results of each cluster, namely C0 there is one type of pest, namely Fruit Fly, C1 there are 3 types of pests which consist of Yellow Virus, Anthracnose and Thrips, while C2 there are 7 types of pests consisting of aphids, mites, Fusarium wilt, Layu Bakeri, Curly Virus, Mati Pucuk, Puru fruit. This analysis is expected to make it easier for farmers to know the causes of damage to chili plants or related agencies can take action to anticipate the causes of damage to chili plants as quickly as

Abstract

Today is the era of global information technology, where everything is done practically, accurately and up to date with information obtained from anywhere and anytime. Currently scheduling lessons at SMP NEGERI 31 Padang is still done manually by the curriculum section, with previously held a task division meeting with subject teachers. From determining the number of classes, the number of teachers in the school and the number of teaching hours for each teacher are still done manually. The allocation and determination of teachers is an important element in the preparation of subject schedules, but is also a common problem in the schedule preparation process. By building a web-based information system with PHP and MySql programming languages ​​and system modeling using UML (Unified Modeling Language), it is hoped that it can facilitate data processing for students, teachers, and student subject schedules so that fast, precise and accurate results can be obtained at SMP NEGERI 31. Padang.

Abstract

The Balinese are one of the ethnic groups of Indonesia, the majority of which are on the island of Bali, the language used is Balinese with three levels of sor-singgih (tigang soroh) guidelines, namely Basa Kasar, Basa Madia and Basa Alus. Balinese language also has the additions of pangater, seselan and pangiring. To facilitate the search for basic words in Balinese, a stemming process is needed. Stemming is the process of mapping and decomposing the form of a word into its basic form. The stemming process is very important in the information retrieval system process. In this study, the Balinese stemming process used the Rule Base Approach method. The data used in this study are 376 basic words in Balinese. This study aims to design an appropriate stemming application for Balinese stemming. The initial stage in the Balinese stemming process is to carry out the input process, preprocessing, filtering, case folding and tokenization. Each word is subjected to a stemming process to remove the additions of pangater, seselan, and pangiring. The results of the study indicate that the Rule Base Approach method can be used to stem Balinese texts, this can be seen from the results of the accuracy reaching 77.82%. Of course, in testing there are still failures caused by overstemming errors resulting from the stemming process.

Abstract

Currently the corona virus or Covid-19 has developed rapidly and it has been reported that almost all over the world have been exposed to the transmission of the corona virus. Covid-19 has claimed thousands of human lives in China in just 3 months. This virus has even spread to other countries such as Italy, Iran, South Korea, England, Japan, America, Germany, and even in Indonesia. One of the provinces in Indonesia that has contracted the corona virus is the province of Central Java (Prov. Central Java). This corona virus has spread in various districts and cities in Central Jawah. There are 35 districts / cities in Central Java that have contracted the corona virus. To make it easier for the Central Java regional government to take measures to prevent the spread of the corona virus, it is necessary for researchers to determine the level of spread of the corona virus which is divided into three clusters. The first cluster is C0 with a low category, C1 with a medium category and C2 with a high spread category. In the analysis of the spread of the corona virus, the researchers used data mining methods and the K-Means Clustering algorithm to classify the distribution data. Then in data processing researchers use the Rapidminer Studio 7.6 application. From the results of the study, it was found that C0 there were 18 cities / districts, C1 there were 1 city / regency and C2 there were 16 cities / districts where the spread of the corona virus was in Central Java province.

Abstract

The development of technology is currently very fast in various fields of human life. One of the uses of technology is in the field of attendance. Attendance is the most important part in an institution, both education, health, offices and government agencies in supporting monitoring of employees' daily attendance. Sokaraja Lor Village is a village located in Sokaraja District, Kab. Banyumas, Central Java. Currently the attendance process at the Sokaraja Lor village office is still using Pinjer Print and also using notes using a ledger. The use of this print pin is considered ineffective because if the village employee's hands are wet, or injured, attendance cannot be done and this is also a risk that village employees can leave absences to other employees. Seeing this, the researchers designed an attendance system based on Face Recognition using the Android platform. Face recognition-based attendance is attendance which is done using the detection of human face parts. Then in designing the face recognition-based attendance system, the researchers used a system modeling with Undifinied Modeling Language (UML). With the construction of this attendance system, Sokaraja Lor Village can make attendance easier in every condition because it is based on Android, then in recapitulating the list of employees who are present, the village government is easier because it has been stored in a database.
