Abstract

The form of an archipelago and densely populated country of Indonesia has its own constraints in efforts to deal with health, especially health for patients with cardiovascular disease. This disease is one of the highest causes of death in Indonesia. Based on data from the Ministry of Health, cardiovascular disease since 2007 is the highest cause of death in Indonesia with more than 220,000 deaths each year. While the number of cases exceeds tuberculosis, which has a death toll of 127,000. The number is increasing every year due to changes in lifestyle of Indonesian people who like to eat high-fat foods and lifestyle factors that affect the risk of cardiovascular disease, including lack of physical activity, smoking, high-fat diets, and alcohol consumption habits. This study aims to monitor the heart rate of cardiovascular sufferers with the internet of things (IoT) approach. Every patient with cardiovascular disease can be monitored using a sensor connected to a PC to record any changes that occur. The research method consists of several stages, namely: Prepare, Plan, Design, Implement, Operate and Optimize (PPDIOO). The results obtained in the form of a prototype heart rate monitoring system for patients with cardiovascular. The patient's health can be monitored at any time by the hospital doctor without the patient having to come regularly to the hospital.

Abstract

The level of internet usage continues to increase until now.  information exchange requires security that cannot be predicted by others.  one technique for securing information is steganography.  Steganography techniques are the science and art of hiding information.  This technique can hide the content of information in media that cannot be guessed by ordinary people, so as not to arouse suspicion of the people who see it.  One of the media that can implement the white-space modified steganography method is HTML pages.  in addition, AES (Advanced Encryption Standard) is a lighter encryption security algorithm compared to other algorithms. In this study, plain text that has been encrypted into cipher text is then inserted with white-space and white-space modification steganography techniques. Data changes have occurred but only less than 1 percent.  In experiments that have been implemented on Google Chrome and Mozilla Firefox are the same except in Internet Explorer, which changes the data slightly larger.The implementation of AES encryption and stegano white-space original, has 100% success but the 80% decryption process is successful, but the decryption results contain additional binaries. This happen because the use of tabulation (tabs) instead of spaces in HTML5 articles, and this is often found in HTML articles. while the implementation of AES encryption and stegano whitespace modified, has a success of 100% and the decryption process of 90% succeeded without any changes. 1 article failed because the number of articles is too small compared to the amount of space provided. The conclusion that implementation of AES encryption and white-space modified is more appropriate to be implemented in HTML5 articles, and than the use of tabulation and the number of characters also consequences on the implementation.Keywords: Information, Steganography, White-space modified, Security, AES, Web Browser

Abstract

Klasifikasi teks adalah salah satu metode untuk mengelola dan mencari informasi penting yang terdapat pada format tekstual yang tidak terstruktur. Ekstraksi fitur merupakan proses penting pada klasifikasi teks untuk mengubah format tekstual yang tidak terstruktur menjadi terstruktur sehingga dapat diproses oleh algoritma machine learning untuk mengklasifikasikan ke class yang telah ditentukan. Salah satu teknik ekstraksi fitur yang umum digunakan adalah vector space representation. Teknik ini mudah digunakan tetapi berpotensi menghasilkan data dengan dimensi banyak yang berakibat kepada peningkatan waktu komputasi bahkan tidak dapat diproses karena limitasi perangkat keras. Pada riset ini kami melakukan studi terhadap teknik ekstraksi fitur yang mampu menghasilkan data berdimensi sedikit. Ekstraksi fitur yang digunakan memanfaatkan vektor word2vec untuk mengontrol jumlah fitur yang dihasilkan. Pada riset ini kami membandingkan beberapa model yang dihasilkan sendiri dengan jumlah fitur yang bervariasi dan model yang telah disedikan oleh Google. Hal ini dilakukan untuk mengetahui jumlah fitur yang dapat menghasilkan kinerja klasifikasi terbaik. Hasilnya didapat nilai kinerja tertinggi akurasi yaitu 0.877 dengan jumlah fitur adalah 300 dari model yang dihasilkan sendiri.

Abstract

The progress of the development of information technology, communication and SOA (Service Oriented Architecture) that is very fast making all activities of aspects of human life must follow. Especially creating long distance shopping and transactions, one way to avoid the crowds and chaos of people when conditions (epidemics that are simultaneously contagious everywhere, covering large geographical areas) the COVID-19 pandemic. Among them are business, business, education, and other activities. Constraints developing applications, it is very difficult and expensive and requires a long time due to differences in platforms between applications and limited access to the server for the security of the server itself. SOA can solve this problem, can make existing programs become service oriented. This can be done with programs that have been built in a modular manner so that it is enough to only add web services techniques in them. Then a service interface is created without changing the logic of the program. Thus the testing is sufficient on the interface, while the function / logic in it does not need to be tested again because it does not change. SOA integrates and accelerates Multi-Partner business processes, all of which can improve efficiency in all fields. Based on this fact this research was conducted. The research method begins with a literature study, and documentation of related journals as a reference source for analysis. Then proceed with direct observation, conducting interviews with several Mall partners; store owner, banks, residents / customers in the Mall (the author is not allowed to mention the name of the store owner, customer name, name of the store owner, and the name of the Mall) to get the required data Modeling the system design process of the Unified Modeling Language, Enterprise Architect and tenology used by SOA. The system development method uses Prototype. The end result of this research (study) is expected to be used by related parties in developing remote transactions and other parties interested in SOA.

Abstract

Vanilla (Vanilla planifolia Andrews) is an industrial plant that has high economic value as a foreign exchange-producing export commodity that is still potential to be developed in Indonesia. Vanilla is widely used in Indonesia as an auxiliary material for the food industry and in fragrance medicine. However, the high demand for vanilla is not balanced with an adequate level of productivity due to several obstacles in the development of vanilla in Indonesia. The main cause of obstacles in vanilla cultivation in Indonesia is the lack of understanding of vanilla farmers regarding diseases that attack vanilla plants. Therefore in this study an expert system was built that could diagnose vanilla plant diseases based on knowledge obtained from the experts directly. Expert system is built based on the web using the PHP programming language and Mysql database. The inference method used is the Dempster-shafer method. In this study consisted of 5 diseases and 16 symptoms  data. Test results show that: (1) Expertise testing by comparing the results of expert diagnoses and the system is appropriate and runs very well with a total average accuracy of 99.50% (2) External testing using a questionnaire involving 20 respondents namely "students of the Plantation Plant Cultivation" show that the system built has an average total percentage value of 82.5% with the category "Very Good".
