Organisasi Kesehatan Dunia (WHO) secara resmi menyebut virus Covid-19 sebagai pandemi global, oleh karena itu semua negara di dunia berusaha meminimalkan dampak yang ditimbulkan oleh virus tersebut, yaitu dengan mengembangkan vaksin. Dalam konteks pandemi Covid-19, pemerintah Indonesia juga meminta dan mendorong masyarakat untuk turut serta mendukung vaksinasi, namun upaya tersebut sebenarnya memiliki kelebihan dan kekurangan, sehingga banyak masyarakat yang mengutarakan pendapatnya di jejaring sosial salah satunya Twitter. Penelitian ini bertujuan untuk mengetahui hasil penerapan analisis sentimen dan mengukur performansi algoritma Naïve Bayes Classifier (NBC) dan Support Vector Machine (SVM) terhadap data vaksin Covid-19 dengan cara mengklasifikasikan data tersebut ke dalam kelas positif dan negatif. Data tweet yang didapat kemudian dilakukan text preprocessing untuk mengoptimalkan pengolahan data. Terdapat 4 tahapan text preprocessing antara lain Case Folding, Tokenizing, Filtering, dan Stemming. Penelitian ini mengkaji kinerja Naïve Bayes Classifier (NBC) dan Support Vector Machine (SVM) dengan menambahkan teknik TF-IDF (Term Frequency-Inverse Document Frequency) yang bertujuan untuk memberikan bobot pada hubungan kata (term) sebuah dokumen. Kemudian melakukan splitting data yaitu membagi data training 80% dan data testing 20% dengan harapan mendapatkan model dengan performansi terbaik dan yang terakhir melakukan visualisasi data tweet dengan menggunakan Word Cloud agar bisa menarik sebuah kesimpulan. Hasil klasifikasi data tweet vaksin Covid-19 menggunakan algoritma Naïve Bayes Classifier mendapatkan nilai accuracy sebesar 81%, precision sebesar 80%, recall sebesar 99%, dan f1-score sebesar 89%, Sedangkan untuk algoritma Support Vector Machine mendapatkan nilai accuracy sebesar 87%, precision sebesar 88%, recall sebesar 96%, dan f1-score sebesar 92%.
世界卫生组织(世卫组织)正式将Covid-19病毒列为一种全球性流行病,因此世界上所有国家都在努力通过研制疫苗来减少这种病毒的影响。在Covid-19大流行的情况下,印尼政府也呼吁并鼓励公众参与疫苗接种,但这些努力实际上是有优点和缺点的,因此许多人在Twitter上的社交媒体上发表意见。本研究旨在确定情绪分析的应用结果,并测量Covid-19疫苗数据对Naive Bayes Classifier算法(NBC)和SVM支持机(SVM)对Covid-19疫苗数据的检测结果,并将其归类为正或负类。然后执行微博数据,以优化数据处理。有四个步骤的预习文本,包括一个箱子折叠,Tokenizing,过滤和印章。该研究通过增加TF-IDF技术(tf - inive - Bayes Classifier)和SVM支持机(SVM)的性能,以增加文件关系的分量。然后筛选数据,即分割培训数据80%和测试数据20%,希望获得最佳表现,最后使用Word Cloud进行数据可视化推文模型得出结论。Covid-19疫苗的推特数据分类使用了Naive Bayes算法为81%,精确为80%,99%为回忆,f1分数为89%,而支持矢量算法为87%,准确为88%,准确为96%,f -score为92%。

Stroke is the number one cause of disability and the second cause of death in the world. Blood flow that is not smooth in stroke patients causes hemodynamic disorders including changes in the value of oxygen saturation in the blood (SpO2) which can interfere with the function of internal organs including the heart due to lack of oxygen intake. So we need a system to monitor the oxygen saturation value which can be used as an early indicator in recognizing stroke patients. This system uses detection of two sensors to measure oxygen saturation in the blood, a microcontroller to process data, a monitor to display data, a buzzer as a warning of the lower limit of measurement and a micro sd card module to store measurement data that has been running. Parameters displayed include the date of measurement, patient ID, SpO2-1, SpO2-2, last SpO2-1 and last SpO2-2. This system will measure and display the SpO2 value of both right and left arms simultaneously. Stroke patients who experience muscle weakness in one hand may experience different values with a hand that does not experience muscle weakness. This study aims to develop an SpO2 monitoring system that will be used to detect stroke patients with non-invasive methods. The results show that the system has been developed and can be used to measure the patient's SpO2 from both hands simultaneously with a measurement error rate of ±2% for each sensor from standard medical equipment.
中风是世界上导致残疾的头号原因,也是导致死亡的第二大原因。中风患者的血流不顺畅会导致血液动力学紊乱,包括血液中氧饱和度(SpO2)的变化,这可能会由于缺氧而干扰包括心脏在内的内脏器官的功能。因此,我们需要一个监测血氧饱和度的系统,以作为识别脑卒中患者的早期指标。本系统采用两个传感器检测血氧饱和度,单片机处理数据,显示器显示数据,蜂鸣器报警测量下限,sd卡模块存储已运行的测量数据。显示的参数包括测量日期、患者ID、SpO2-1、SpO2-2、最近的SpO2-1和最近的SpO2-2。该系统将同时测量并显示左右两臂的SpO2值。一只手肌肉无力的中风患者可能会用另一只没有肌肉无力的手体验到不同的价值。本研究旨在开发一种SpO2监测系统,该系统将用于无创方法检测脑卒中患者。结果表明,该系统已研制成功,可用于同时测量患者双手的SpO2,标准医疗设备的每个传感器的测量错误率为±2%。

Water is very important for all aspects of life on earth, agriculture is one of the fields that really need large amounts of water because of the use of water in the process of plant photosynthesis. Water that has good quality is if the water is not excessively polluted by harmful chemicals or minerals. One indicator that water is polluted is a change in temperature and pH (acidity) of the water. Temperatures that are too hot in the water will interfere with the growth of plants and other microorganisms. While the normal pH of water has a pH that ranges from 6.5 to 7.5. The quality of water and soil is very important in agriculture. The level of acidity (pH) and soil temperature are one of the things that affect plant fertility. Therefore, the quality of water and soil on agricultural land is one of the important things that needs special attention in its management. One solution so that water and soil quality can be monitored and managed efficiently is to utilize a Wireless Sensor Network based on the Internet of Things (IoT). The use of the ESP8266 Module as a WIFI module, is widely used by Internet of Things-based applications because the price is cheap so it reduces a lot of costs and has a fairly good speed of 80 MHz. This study aims to develop the concept of a Wireless Sensor Network by utilizing the ESP8266 module to monitor pH values using a pH Meter Analog Kit sensor and temperature from agricultural land using a DS18B20 Waterproof sensor and can be monitored at any time using a smartphone.
水对地球上生命的各个方面都很重要,农业是真正需要大量水的领域之一,因为植物光合作用过程中要用到水。水质好的水是指没有被有害化学物质或矿物质过度污染的水。水被污染的一个标志是水的温度和pH值(酸度)的变化。水温过高会影响植物和其他微生物的生长。而正常的水的pH值在6.5到7.5之间。水和土壤的质量在农业中非常重要。酸度(pH)和土壤温度是影响植物肥力的因素之一。因此,农用地水土质量是农用地管理中需要特别关注的重要问题之一。有效监测和管理水和土壤质量的一种解决方案是利用基于物联网(IoT)的无线传感器网络。使用ESP8266模块作为WIFI模块,由于价格便宜,被物联网应用广泛使用,因此降低了很多成本,并且具有80mhz的相当不错的速度。本研究旨在开发无线传感器网络的概念,利用ESP8266模块使用pH计模拟套件传感器监测pH值,使用DS18B20防水传感器监测农业用地的温度,并可随时使用智能手机进行监测。

The behavior of changing the use of technology for business actors is very rapid. Information of system is form of data that has been processed through a certain model into information that can be used by the recipient in making decisions. Some MSME actors with a Data List of product images and detailed information on their products to be marketed to customers using laminated paper. Marketing information using the Website implements CMS with E-Catalog as an alternative solution. Reader and Viewers can view the Catalog privately or together. The treatment of the Plugin model with the CMS that has been embedded on the website is reliable because it is online. Several list images are displayed on WhatsApp Status and social media to introduce products to the public with the aim of increasing sales volume and selling in the market. This is an obstacle if one day people need pictures but do not have complete detailed information. High purchasing power is expected to be created from the spread of E-Catalog regarding products from MSMEs that have been installed on the E-Catalog website. Websites with online CMS can be opened on any device by requiring an internet connection, making it easier for marketing and complete information for consumers, customers and MSME business players.
改变业务参与者使用技术的行为是非常迅速的。系统的信息是通过一定的模型处理成信息的数据形式,可以被接收方用于决策。一些MSME参与者使用层压纸向客户推销产品图像和详细信息的数据列表。营销信息使用网站实现CMS与电子目录作为替代解决方案。读者和查看者可以单独或一起查看目录。处理插件模型与CMS已经嵌入在网站上是可靠的,因为它是在线的。在WhatsApp Status和社交媒体上展示几张列表图片,向公众介绍产品,目的是增加销量,在市场上销售。这是一个障碍,如果有一天,人们需要图片,但没有完整的详细信息。在电子目录网站上安装的中小微企业的产品,随着电子目录的普及,预计将产生较高的购买力。具有在线CMS的网站可以通过互联网连接在任何设备上打开,使其更容易为消费者,客户和中小微企业玩家进行营销和完整的信息。

Perancangan aplikasi PANTAU ditujukan untuk petani yang mendapatkan bantuan hibah tanaman untuk penghijauan dan komersil. Dalam aplikasi pantau ini organisasi yang bekerja sama dengan petani dapat memantau perkembangan tanaman yang dihibahkan dan petani dapat mengirimkan informasi kondisi tanaman secara up to date melalui masing masing akun yang dimiliki. Dalam perancangan UI/UX aplikasi PANTAU digunakan design thinking method untuk mengetahui kebutuhan perancangan sesuai dengan yang dibutuhan user. Dan untuk testing menggunakan heuristic evaluation dan usability testing untuk mengetahui keefektifan dari rancangan UI/UX aplikasi PANTAU. Adapun testing ditujukan pada 22 user yang terdiri dari petani, organisasi dan pengelola sistem.

Penerapan Metode Playfair Cipher Dalam Aplikasi Enkripsi- Dekripsi File Teks 在加密应用程序解密文本文件中使用Playfair加密方法
Pub Date : 2022-12-04 DOI: 10.51903/elkom.v15i2.937
Taufan Maynard Prananda Sancaka1, Veronica Lusiana
Dokumen Teks adalah dokumen yang menyajikan informasi secara tertulis. Ada berbagai jenis dokumen teks, antara lain Plain Text ( .txt ), Microsoft Word Documents ( .docx ), Portable Document Format ( .pdf ) dan lain sebagainya. Dokumen teks ini sangat penting karena berisi data dan informasi dari pihak-pihak yang berkepentingan. Untuk meningkatkan keamanan dari kebocoran data atau informasi, diperlukan suatu teknik yang disebut Kriptografi. Kriptografi adalah ilmu yang mempelajari tentang keamanan pesan, sehingga membuat pesan tidak dapat dibaca oleh orang yang tidak berwenang. Oleh karena itu penulis menggunakan metode Kriptografi yang bernama Playfair Cipher untuk diimplementasikan pada sebuah aplikasi agar aplikasi tersebut mampu mengubah file teks menjadi file terenkripsi dan sebaliknya. Untuk menganalisa proses pada aplikasi, penulis menggunakan beberapa file diantaranya ( .txt ), ( .docx ), dan ( .pdf ). Sehingga dari hasil analisis tersebut dihasilkan suatu kesimpulan bahwa semakin besar ukuran file yang akan melalui proses enkripsi atau dekripsi maka akan semakin lama pula proses enkripsi atau dekripsinya. Aplikasi yang dihasilkan akan membantu mengubah file teks menjadi file terenkripsi dan sebaliknya.
文本文档是一种以书面形式呈现信息的文档。有不同类型的文本文档,包括Plain Text (.txt)、微软Word文档文档(.docx)、便携式文档格式(.pdf)等。这些文本文件非常重要,因为它们包含有关各方的数据和信息。为了加强数据泄露或信息的安全,需要一种叫做密码学的技术。密码学是一门研究信息安全的科学,因此使信息不被授权的人阅读。因此,作者使用一种名为Playfair密码的加密方法在一个应用程序上实施,使该应用程序能够将文本文件转换成加密文件,反之亦然。为了分析应用程序的进程,作者使用了其中的一些文件(.txt)、(.docx)和(.pdf)。因此,分析得出的结论是,通过加密或解密的文件体积越大,加密或解密的时间就越长。生成的应用程序将有助于将文本文件转换成加密文件,反之亦然。
