Before the recycle process, the inorganic garbage will be grouped which needs an identification of its form of material. The digital image processing can be used to create a system which could identify the form of material the inorganic garbage is by analyzing the features. In this research, the feature that will be used is the texture feature. The texture feature will be extracted using the Gray Level Co-Occurrence Matrix, and Gray Level Run Length Matrix method. And for the material of garbage identification will use the Improved KNN classification method. The results of the test by using 50 images as data testing from 5 different material of garbage which is cardboard, glass, metal, paper, and plastic type of garbage have the highest mean of accuracy 90,4% by using the GLRLM method with 135° angle of extraction. Meanwhile the accuracy when combining the extraction methods, which is adding up the value of GLCM and GLRLM, have the highest mean of accuracy 88% with 0° angle of extraction","PeriodicalId":79040,"journal":{"name":"Explorer","volume":"87 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82073252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Algoritma C.45 dapat digunakan dalam pembentukan pohon keputusan tetapi lebih mengarah pada perhitungan probabilitas dari tiap-tiap record terhadap kategori-kategori tersebut atau untuk mengklarifikasi record dengan mengelompokan ke dalam satu kelas. Setelah sebuah pohon keputusan dibangun maka dapat digunakan untuk mengklarifikasi record yang beulm ada kelasnya. Dimulai dari node root menggunakan tes terhadap atribut dari record yang belum ada kelasnya, kemudian mengikuti cabang sesuai dengan proses pohon keputusan yanitu mengubah bentuk data (table) menjadi pohon (tree) kemudian merubah model pohon tersebut menjadi aturan.

With security that is not always maintained, especially outside working hours, the authors make a room security system design to open the room only with registered fingerprints and programmed active telephone numbers, so that it cannot be accessed by others. This design is made with several components, namely Arduino as a data processor for the entire work system, the fingerprint reader functions to recognize the fingerprints to be registered, to enter the OTP code using the matrix keypad, Liquid Crystal Display (LCD) to display the data provided by Arduino through the program. that has been made, the relay is used to activate the solenoid, the solenoid functions to open or lock the door, the buzzer will sound when the fingerprint and password are not read, the GSM SIM900A module functions to send an OTP code using an active cell phone number, and the MC-38 magnetic sensor to know if the door is open or still closed. From this test it can be concluded that only the fingerprints of people who have been registered and the telephone numbers that have been programmed to be able to open the door of the room.

Marketplace sites are third parties in online transactions. Many resellers use the site to make sales transactions. However, when we engage in online sales, there are many factors that must be considered, one of which is replying to customer chat messages. This is very important in the world of sales even required to respond quickly. The problem is that sometimes resellers have activities other than selling online, so sometimes customer messages are late in responding and even unresponsive. This study aims to determine how effective and efficient it is in handling customers using Chat Bot Messenger. The research method used is blackbox to determine the application function is running well and to evaluate the usability of the system using the System Usability Scale (SUS). The test results produce an average value of 81 which means users like the application that is used because it is able to provide convenience during sales transactions.","PeriodicalId":79040,"journal":{"name":"Explorer","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81520997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From this problem, a decision support system is needed to help aid distributors select people who are entitled to be given assistance with the Simple Additive Weighting (SAW) method approach and the results of this decision will be obtained from 1-15 candidates who really deserve to get city government assistance and reduce fraud in providing assistance during the Covid-19 Pandemic.","PeriodicalId":79040,"journal":{"name":"Explorer","volume":"PC-25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84854202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
