<em>The word uncertainty in an expert system is related to working with wrong data, wrong information, handling identical situations, the reliability of results, etc. Sources of uncertainty can come from unreliable information. This is usually caused by unclear domain concepts or for inaccurate data. One method for overcoming uncertainty is Dhempster-Shafer's theory. Dempster-shafers come up with approaches to calculate probabilities to look for evidence based on trust functions. In general the Dempster-Shafer theory is written at an interval [Confidence, Reasonable]. Belief (Bel) is a measure of the strength of evidence in support of a series of propositions. In this study an expert system will be developed to diagnose oral cancer that can recognize oral cancer based on the symptoms felt by the user. The results showed the Dempster-shafer was able to overcome the uncertainties in the construction of the inference engine, this is because the accuracy of the test results showed an accuracy of 86.6% Dempster-shafer</em>.
Oral cancer or oral cavity cancer is cancer that attacks the epithelial tissue of the oral mucosa. Cancer is a disease with a high mortality rate. Therefore, it is very important to be able to provide knowledge assistance to people who are still quite low in knowledge about cancer, especially oral cancer. One way to help diagnose disease is to use an expert system. In this study, an expert system application was developed to diagnose oral cancer based on symptoms and produce a diagnosis and treatment solution. The expert system developed using the certainty factor algorithm (CF). Where is able to overcome uncertainty by providing a value level of trust from experts and users. From the results of the accuracy test, it shows a value of 87%, so the system can function properly.
Sensus Penduduk Indonesia 2020 (disingkat SP2020) adalah pendataan penduduk Indonesia yang mencakup jumlah penduduk, etnis, agama, pekerjaan, perekonomian, dan lain-lain. Sensus 2020 adalah sensus yang ke-7. Dalam Sensus Penduduk kali ini ada yang berbeda, yakni Sensus Penduduk Secara Online. Kelebihannya Dapat dilakukan kapan saja secara mandiri selama periode pelaksanaan Sensus Penduduk Online, Literasi masyarakat terhadap penggunaan teknologi informasi yang semakin baik., Menumbuhkan kesadaran masyarakat tentang arti penting data, dimulai dari informasi pribadinya. Namun dalam pelaksanaannya terdapat berbagai kendala, Koneksi Internet yang tidak optimal, Belum pahamnya masyarakat dalam menggunakan Gadget dan lain-lain, sehingga diperlukannya Sosialisasi dan pendampingan langsung dalam pengisiannya
The teacher (educator) is a guide in carrying out the teaching and learning process. Teachers usually have different tasks such as classroom teachers, subject teachers and private teachers. Private teachers usually provide material or teaching specifically to their students not formally like in school. There are types of private teachers according to the expertise of each teacher, one of which is a private video editing teacher. In Bandar Lampung it is very difficult to find information related to private video editing teachers, causing students who want to find private video editing teachers to find it difficult and time consuming. So in this study developed an Android-based application that can make it easier to find private video editing teachers in Bandar Lampung so that the search for private tutors is easier and faster. This application was developed using the extreme programming (XP) system development method where, this method can be in tune with changes in design and features with flexible handling. Based on usability testing, the average value was 82.5%, and it was in the good category.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
