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%.

Information technology is a very important means ofinformation for a company. Information is expectedto facilitate work or activities to achieve goalsoptimally. With the increasing popularity of theinternet, many business fields, especially large-scaleones, have provided online services, but this is notthe case for small and medium-sized businesses suchas the car rental business, by utilizing web servicesthat contain information and ordering applications, itis hoped that they will become promotional mediaand will expedite the ordering process. The researchmethod used in building a rental car bookingapplication with web services is by means of needsanalysis, system design, database design, and screendialog design.

At this time the learning process is still partially carried out online (in the network) considering the positive cases of Covid-19 that still exist in the Semarang City area. The implementation of online learning is not without problems, even in several countries, especially Indonesia, it is reported that countries that adopt online learning on average are actually much smaller than expected. The implementation of online learning makes students less understanding of the learning materials provided and students' low interest in learning during the pandemic. This study aims to create a learning application for grade VI elementary school students that contains learning materials, practice questions that are randomized using LCM and facilitate the results of the assessment of the questions. From the results of LCM randomization, each student did not get the same or twin questions. From the test of 3 students, it was found that the questions that appeared in the same order were question number 6, while the questions that appeared in a different order were questions number 2, 3, 4, 5, 7, 8, 9, 10

Starting from the development of medical technology that is increasingly sophisticated and rapidly growing,researchers conduct medical research, namely about patient infusion handling services. In handling patient infusion, currently it is still manual which is carried out by nurses / medical personnel. Infusion handling services for patients still have shortcomings, namely the process of monitoring and replacing infusion fluids which are often late. If the problem is not treated quickly, it can lead to problems, namely the presence of air embolism in the blood vessels (the entry of foreign objects into the blood vessels, for example air). From that problem, the researchers made a new innovation in medical technology in handling infusions automatically and based on IoT. In this study, the smart online infusion device that has been made has good features and is very effective in handling infusions. This device has 3 main functions, namely: it can monitor the remaining infusion, it can change the infusion fluid automatically and it can indicate a blocked patient's infusion. This device already has a method for processing data with fuzzy logic. Media monitoring has been supported by a website that can be controlled remotely and in real time. Tests have been carried out and the effectiveness of the system is found to have an error rate of 0.2% - 0.7% and has an accuracy of 98%. Thus this tool can be used in terms of handling patient infusion automatically.

The current era is the era of globalization, and many companies are starting to develop with increasingly sophisticated technology. CRM is a comprehensive tactic from the company so that every process of the customer life cycle can be utilized optimally. The purpose of this study was to establish a website for the CRM-based WiassShop Shoe Store. The method that will be built in this research is a website-based information system at WiasShop using the Waterfall system development method. The use of this method begins with listening to all obstacles, obstacles and suggestions from customers. Then a system design will be carried out that is tailored to the needs and complaints that have been submitted by customers, after which the development design is implemented in the form of a website. After that, the system will be tested to find out where the bugs (weaknesses) are, which will later be repaired and refined. This system will be built using Php Native and using MySQL database. Hasil penelitian yang penulis buat dengan judul Rancang bangun website pada toko sepatu wiasshop berbasis CRM adalah untuk memudahkan pengelola Wiasshop dalam melakukan pengolahan data produk, memudahkan dalam pencatatan data transaksi,dan mempermudah user dalam melakukan pembelian produk.

Universitas Ilmu Komputer dan Teknologi (STEKOM University) telah menggunakan Learning Management System (LMS) sejak tahun 2018, namun hingga saat ini pengukuran kinerja Learning Management System (LMS) belum dilakukan.

Tambangan Village is one of the urban villages in Semarang City that is active in managing PKK so that it has received several awards in managing the PKK program at both the city and provincial levels. The administrative process in Tambangan Village still uses manual methods both in data recording and recapitulation. This causes several problems that often become obstacles in the PKK administrative process in Tambangan Village, namely there is often scattered data, writing errors, recapitulation of the amount of data that is less accurate and the reporting process is complicated, causing the administrative process to take a long time and information that is incomplete. produced less accurate and inappropriate in the field. This study aims to create a PKK information system in Tambangan Village that can be used to manage data and information for dawis groups, PKK members, PKK activities, the presence of PKK members and Posyandu activities. The results of the questionnaire test from the use of the PKK information system that was built were measured using a Likert scale and the results were 92% with a very satisfied category.
