Abstract

The utilization of information technology in learning has functioned as a tool in the teaching and learning process during the Covid-19 pandemic. The need for the availability of a learning platform using LMS (Learning Management System) or free e-learning that is easily obtained from the public network (internet) makes the utilization of the learning platform indispensable for the teaching and learning process. Learning platforms available on the internet can also be used independently by students. However, not all existing learning platforms can be used as the appropriate means to improve the quality of education. The educator policies are needed to utilize the existing learning platforms so that learning objectives can be achieved. This study will analyze how to choose the right learning platform for an educational institution using SAW (Simple Additive Weighting)-based Fuzzy Multiple Attribute Decision Making (FMADM) method. FMADM is a method used to find the optimal alternative from a number of alternatives with certain criteria. The purpose of this study is to assist educators in deciding the most appropriate learning platform that can be used to support the teaching and learning process during the Covid 19 pandemic.

Abstract

In recent years, the progress of the culinary business in the city of Semarang has increased. This is marked by the emergence of a lot of business creativity that follows consumer tastes. This creativity can be seen from the variety of culinary product variants sold by culinary entrepreneurs. From the research that has been done, there is still no research that filters and gives grade on food or drink in order to provide prices that are in accordance with the quality of food or drinks. Therefore to address the needs of culinary entrepreneurs, it takes an application of Culinary E-Business that can be a bridge for culinary entrepreneurs in the city of Semarang to receive orders online. It is expected that this application can determine food quality standards that will be marketed through this e-business application by providing grade A, B, and C. labels To determine food grade, this study uses the K-Nearest Neighbor method. By determining the price standards for similar foods, so there is no price competition for similar foods that can lead to the death of food entrepreneurs with small capital. So that it can move the people's economy by providing the means to expand the regional food marketing network, so that food entrepreneurs have a greater chance to develop.

Abstract

Web-based degree document certification system with a digital signature in Semarang University has a purpose to support academic to do online document certification through a system. The main problem which occurs in academic administration is a long document certification process that causes an ineffective and inefficient certification process. To solve the problem, a system that can encrypt a document for better security is required. This system is built with the advanced encryption standard algorithm with a 128-bit sized key to encrypt confidential information inside the document. During the encryption process, this algorithm operates using 4x4 bit array blocks and passing many encryption processes for at least 10 (ten) times. The application is analyzed with object-oriented analysis and modeled with Unified modeling language. The result of this research is a system which can secure document with AES algorithm with a 256-bit sized key. The security element in this algorithm will make easier to identify the owner of the document. The secured document is easily accessible through PHP-based web or available QR code. When decrypting the document, the application will activate the camera function and decrypt the information document.

Abstract

Pandemi COVID-19 (Coronavirus) cenderung menjadi salah satu masalah paling serius global dalam satu tahun terakhir ini. Negara tidak memiliki pengalaman serupa terkait penyebaran virus dan dampaknya dari berbagai bidang. Memperkirakan jumlah kasus COVID-19 sebelumnya dapat membantu dalam mengambil keputusan berupa tindakan dan rencana pencegahan virus tersebut. Penelitian ini bertujuan untuk menyediakan model peramalan yang memprediksi kasus COVID-19 yang dikonfirmasi di kota Semarang. Penelitian ini menerapkan algoritma pembelajaran mesin yakni Artificial Neural Network (ANN) untuk memprediksi kasus COVID-19 di kota Semarang. Proses fine-tuning masing-masing model dijelaskan dalam penelitian ini dan perbandingan numerik antara ketiga model disimpulkan menggunakan ukuran evaluasi yang berbeda; mean sequence error (MSE).

Abstract

Pencarian informasi alumni perguruan tinggi dilakukan supaya dapat menentukan seberapa lama masa yang dibutuhkan agar mendapatkan pekerjaan. Dalam tahap peningkatan mutu sebuah perguruan tinggi, alumni mengambil peran penting, sebab kualitas pembelajaran pada perguruan tinggi dapat dikatakan sudah cukup baik apabila alumninya cepat terserap didalam dunia kerja. Pencarian informasi (tracer study) diperoleh melalui kuesioner yang dibagikan oleh pihak USM Career and graduated Class (UCAC) kepada para alumni. Informasi tersebut terdiri dari data-data para alumni pada tahun 2019-2020 dan kemudian digunakan untuk mendapatkan dan memperkirakan lama waktu tunggu yang dibutuhkan para lulusan USM hingga memperoleh pekerjaan setelah dinyatakan lulus studi sarjana. Algoritma KNN digunakan dalam penelitian ini, hal tersebut dikarenakan metode KNN mampu memprediksi masa tunggu alumni dibandingkan dengan metode lainnya. Adapun kompetensi yang berdampak terhadap masa tunggu alumni dalam mendapatkan pekerjaan dapat diperoleh melalui hasil analisis penelitian ini, seperti keterampilan dalam menggunakan komputer, manajemen pengolahan waktu, kemampuan dalam menganalisis, serta disiplin ilmu. Hasil implementasi algoritma KNN dengan mencoba nilai K dari 1-100 yang memiliki akurasi tertinggi mencapai 98,84%. A search for information on university alumni was carried out in order to determine how long it would take to get a job. In the stage of progress in the quality of a university, alumni play an important role, because the quality of learning at a university can be said to be quite good if the alumni are quickly absorbed into the world of work. The search (tracer study) was obtained through a questionnaire distributed by the USM Career and Graduate Class (UCAC) to alumni. This information consists of data from alumni in 2019-2020 and is then used to obtain examples of the length of time to employment needed for USM graduates to get a job after graduating from undergraduate studies. The KNN algorithm was used in this research, this is because the KNN method is able to predict the time to employment for alumni compared to other methods. Competencies that have an impact on the time to employment for alumni to get a job can be obtained through the results of this research analysis, such as skills in using computers, time management, analytical skills, and scientific discipline. The results of implementing the KNN algorithm by trying K values from 1-100 have the highest accuracy reaching 98.84%.

Abstract

The purpose of this study is to contribute to building behavioral intentions through service quality and experience quality. Perceived Value is expected to play a role as a mediation in tourism objects in the city of Semarang. The population is all visitors to tourist attractions in the city of Semarang, while the sample is determined on the basis of Tables Isaac and Michael of 190, respondents are determined using the Proportionate Stratified Random Sampling technique. Path analysis is used as an analytical tool with the Sobel test to determine the results of mediation between exogenous and endogenous variables. The results of hypothesis testing show that behavior intention can be manifested by service quality and experience quality through perceived value as mediation. Perceived value can be implied through service quality and experience quality while Perceived Value directly significantly influences Behavior Intention. The results of the Sobel test calculation show a value of 2.114 meaning that the Service quality and Experience quality variables have a significant influence on Behavioral Intention through Perceived Value. The Adjusted R-Square value obtained is 0.868, meaning that behavioral intention can be explained by service quality, experience quality and perceived value of 86.8% and the remaining 13.2% is explained by other variables outside this study
