Abstract

The benefits of Medium, Small and Micro Enterprises (MSMEs) carried out by the community are often only sufficient for the needs of daily life, have not yet reached the development stage. The community of MSME actors is faced with the problem of how-to-do-good promotion and marketing, thereby increasing consumers. Community Service Activities carried out by universities can provide a solution to this problem. Digital Promotion and Digital Marketing for MSME actors can be carried out through socialization and training. This of course is something that must be done so that MSME actors can adapt to the current digital era. This community service is carried out in Bukit Lawang Village. Business development is the target to be achieved for MSME actors.Keywords: Community Service, MSMEs, Digital Promotion, Digital Marketing, Business Development

Abstract

The Internet of Things is a growing field of research in the era of globalization revolution 4.0. The development of information technology is also developing human interests and abilities regarding information technology, seen from several aspects that make human competitiveness superior. Internet of Things is a concept that optimizes internet connectivity in enabling humans to interact with electronic equipment connected to the internet network. The use of computers in the future will dominate human work to control electronic equipment remotely. To apply the Internet of Things concept, devices that are able to work optimally are needed, such as the NodeMCU as Hardware in a Microcontroller circuit in which a System on Chip (SoC) is embedded, namely the Wifi module and also a Blynk App Software to control the work of the Hardware.

Abstract

Teknologi informasi adalah suatu proses dari mulai mendapatkan data hingga mengolah dan menganalisis data tersebut sehingga tersimpan dengan berbagai cara untuk membuat atau menghasilkan informasi yang berkualitas. Saat ini perkembangan teknologi informasi sangatlah pesat dan cepat termasuk di indonesia sendiri maka dari itu penelitian ini mengeksplorasi perancangan sistem informasi berbasis website, "Medan Wedding Organizer," yang bertujuan untuk memfasilitasi pasangan pengantin dalam mencari, memilih, dan memesan layanan wedding organizer secara efisien di Medan. Teknologi informasi digunakan sebagai alat untuk mendapatkan, mengolah, dan menganalisis data guna menghasilkan informasi berkualitas. Peningkatan pesat dalam teknologi informasi telah menciptakan peluang bisnis baru, seperti marketplace dengan banyak vendor dan industri wedding organizer yang berkembang pesat. Analisis data dilakukan melalui pengumpulan data dari studi pustaka, wawancara, observasi, dan data profil jasa Wedding Organizer. Perancangan sistem menggunakan metode prototyping, yang melibatkan Customer dalam setiap tahap perancangan, sehingga menghasilkan sistem yang sesuai dengan kebutuhan Customer. Sistem ini diuji menggunakan metode black box testing, yang mengidentifikasi masalah atau kesalahan tanpa memperhatikan struktur internalnya. Hasil pengujian menunjukkan bahwa sistem ini memenuhi berbagai kriteria yang diharapkan, termasuk tampilan yang baik dan fungsionalitas yang sesuai. Pembahasan mengungkapkan bahwa sistem ini bertujuan mempermudah seller jasa dalam mempromosikan produk mereka dan memberikan informasi kepada pelanggan. Meskipun sistem ini telah berhasil, masih ada ruang untuk peningkatan, seperti penambahan fitur dan validasi yang lebih ketat pada input seller. Di masa depan, diharapkan pengembangan sistem berbasis mobile untuk meningkatkan kinerja dan aksesibilitas sistem ini.

Abstract

Delta compression uses the previous block of bytes to be used as a reference in the compression process for the next blocks. This approach is increasingly ineffective due to the duplication of byte sequences in modern files. Another delta compression model uses the numerical difference approach of the sequence of bytes contained in a file. Storing the difference value will require fewer representation bits than the original value. Base + Delta is a compression model that uses delta which is obtained from the numerical differences in blocks of a fixed size. Developed with the aim of compressing memory blocks, this model uses fixed-sized blocks and does not have a special mechanism when applied to file compression in general. This study proposes a compression model by developing the concept of Base+Delta encoding which aims to be applicable to all file types. Modification and development carried out by adopting a dynamic block size using a sliding window and block header optimization on compressed and uncompressed blocks giving promising test results where almost all file formats tested can be compressed with a ratio that is not too large but consistent for all file formats where the ratio compression for all file formats obtained between 0.04 to 12.3. The developed compression model also produces compression failures in files with high uncompressed blocks where the overhead of additional uncompressed blocks of information causes files to become larger with a negative ratio obtained of -0.39 to -0.48 which is still relatively small and acceptable.

Abstract

Security of confidential text messages is very important to protect the contents of messages from irresponsible parties. For this reason, the importance of awareness in terms of data security in the current digital era is marked by the development of data security applications. In this study, histogram and PSNR analysis will be carried out in data security applications. The purpose of this analysis is to determine the changes in the histogram and PSNR values of the image that has been inserted a text message. The results of the message insertion in the true color image using the spread spectrum method and the least significant bit visually do not show any change. The number of inserted characters affects the histogram graph, the more the number of characters inserted, the more visible the graph changes in the histogram. The resulting stego image meets the fidelity and recovery criteria. It is evident from the resulting PSNR value, namely PSNR > 30db. Changes in the image extension are one of the factors that cause the PSNR value. It is proven by the .jpg image extension which has the lowest MSE of 0.00251 and the highest PSNR of 74,12625db.

Abstract

The increase in the number of new car releases coupled with the increasingly massive advertisements about the latest cars in the city of Medan, makes consumers or the public more interested and encouraged to be able to exchange (sell) their cars and replace them with the latest cars, so this creates used cars that are still suitable for use to be re-sold and bought to other consumers so that it makes the marketing of used cars very large. This is proven by the large number of requests for used car purchases in the city of Medan to meet their needs for four-wheeled vehicles. Used vehicles, especially 4-wheeled vehicles, have varying prices and are always different from one seller to another, which causes confusion for buyers about used car prices. To overcome this problem, the authors use data mining techniques to predict used vehicles, especially 4-wheeled vehicles. The results applied are make predictions using the gradient boosting algorithm and the linear regression algorithm which produces used car predictions.

Abstract

Consumer satisfaction is a major factor in the service and goods business sector. Efforts to determine consumer satisfaction at the level of performance in terms of service quality contained in PT. BEST is currently conducted through a consumer satisfaction survey. The survey was conducted manually and the form of the interview was not based on the criteria as a standard required for the uniformity of survey material, so it was difficult to carry out further analysis. Therefore, it is necessary to have a system to measure the level of customer satisfaction by applying an analytical method that considers the level of performance between the level of interest or expectations of the respondents. The purpose of this study is to apply the IPA method which is used to find out the attributes that need to be improved or reduced based on the location of the quadrant mapping. The result of this research is a system that is able to determine the level of customer satisfaction based on the level of performance and the level of importance as well as which attributes should be improved or reduced.
