Abstract

Caffe Ayos is a cafe that is quite famous in the Rantauprapat area, but that doesn't mean it doesn't have competition in business. With so many new cafes popping up, of course this could have quite a significant impact if Ayos cafe doesn't first create a strategy to stay afloat. Apart from improving service and maintaining the taste of the menu, there needs to be other things done by Café Ayos, and with the many transactions that occur every day, of course there is a pile of data. From this pile of data, it is hoped that it can provide new knowledge that will be useful later for Café Ayos. Knowledge can be extracted from daily sales transaction data using Acsociation Rule data mining. From the extraction results, we obtained several foods and foods that depend on each other, which have a confidence of up to 70% to 100%. It would be better to create special packages for several menus that are related to high confidence values, thereby providing more attraction.

Abstract

Perkembangan teknologi informasi dan komunikasi yang revolusioner telah membawa dampak besar pada masyarakat, terutama dengan kemunculan media sosial sebagai platform kuat yang membentuk komunikasi dan interaksi sosial. Remaja di usia Sekolah Menengah Atas juga terpengaruh oleh fenomena ini, di mana media sosial menjadi bagian tak terpisahkan dari kehidupan mereka. Melalui media sosial, remaja memiliki kesempatan untuk menyuarakan pendapat, memperluas jaringan sosial, dan membentuk koneksi dengan dunia di sekelilingnya. Namun, media sosial bukan hanya sekadar wadah untuk berkomunikasi dan berkreativitas, tetapi juga menjadi panggung bagi remaja untuk mengadvokasi isu-isu sosial yang mereka pedulikan. Namun, ada potensi risiko serius yang terkait dengan penggunaan media sosial oleh remaja. Salah satu tantangan utamanya adalah penyebaran berita palsu atau hoaks yang dapat dengan mudah menyebar dan memicu kebingungan di kalangan remaja. Hal ini dapat mempengaruhi persepsi mereka tentang isu-isu global. Selain itu, perundungan cyber juga menjadi ancaman serius bagi remaja di dunia maya, yang dapat meninggalkan bekas trauma emosional dan membuat remaja merasa terisolasi dalam kesendirian. Kecanduan media sosial juga menjadi masalah serius yang dapat mempengaruhi kesehatan fisik dan mental mereka. Untuk mengatasi tantangan ini, penting bagi pihak-pihak terkait, seperti institusi pendidikan, orang tua, dan guru, untuk bersinergi dan mencari solusi yang tepat. Edukasi tentang etika bermedia sosial harus diintegrasikan dalam kurikulum sekolah dan orang tua harus terlibat aktif dalam mengawasi aktivitas online remaja. Kampanye kesadaran tentang etika bermedia sosial juga dapat diadakan untuk menciptakan budaya positif di dunia maya. Hasil dari kegiatan penyuluhan diharapkan dapat meningkatkan kesadaran remaja tentang pentingnya berperilaku etis dan positif di dunia maya. Perubahan sikap dan perilaku positif diharapkan terjadi, sehingga remaja dapat menggunakan media sosial secara lebih bertanggung jawab dan menghindari risiko negatif yang terkait dengannya. Dengan demikian, generasi muda akan menjadi lebih cerdas dan tanggap dalam berinteraksi di dunia maya, menciptakan lingkungan digital yang sehat dan aman bagi semua pengguna.

Abstract

The rapid development of ICT has opened up opportunities for citizens to submit opinions and complaints to the Government, which facilities are guaranteed by law. The provision of these facilities is in the form of implementing e-Government. The government must provide an application that is Government to Citizens/Consumers (G2C) which aims to bring the government closer to the community interactively through access channels that can be reached by the community. Labuhanbatu is a district located in North Sumatra Province with a population of 493,899 people. However, until now there is no facility for the public to submit aspirations or complaints based on e-Government applications. This study aims to create a web-based online application for aspiration and complaint services for the people of Labuhanbatu Regency. This application is called LAPO, which stands for Online Aspirations and Complaints Service. The method used in this research is the Waterfall model. This research has succeeded in creating a web-based online aspiration and complaint service system for Labuhanbatu residents that shows the compatibility between the expected results and the actual results. The results of the study have proven that to design and build this system, the following stages are carried out: analyzing system requirements, system design, implementing the system, and conducting system testing. With this research, it is hoped that it can become one of the e-Government applications for aspiration and complaint services that can be used by the Labuhanbatu Regency Government easily and with low infrastructure costs by utilizing existing human resources.

Abstract

Estimation of photosynthetic pigment levels from leaves can be done using conventional methods using laboratory equipment such as spectrophotometers and using digital image processing from leaf images with a computational model. In digital image processing methods, various models are used, such as neural network, CNN, and linear regression. Measurement of photosynthetic pigment levels using image processing methods uses color value data from image data as input to the model used. In this study, we will analyze the effect of various types of color space and inpaint preprocessing settings on the accuracy of the CNN model in measuring leaf photosynthetic pigment levels. The color space types being tested are 4 single color spaces RGB, HSV, LAB, and YCbCr, as well as 6 color combination spaces RGB+HSV, RGB+LAB, RGB+YCbCr, HSV+LAB, HSV+YCbCr, and LAB+YCbCr. The choice of the type of color space takes into account the phenomenon of color constancy and the characteristics of the color space on the lighting elements. In addition, image data is divided into two types, namely through inpaint preprocessing and not, so that in total there are 20 types of input data. After the CNN model training process with various types of color spaces and different preprocessing settings as input data, observations were made on the accuracy values, namely the training MAE and the validation MAE for each model. From 20 types of input data, 3 types of input data are obtained which are recommended as input data that provide the best model accuracy value based on MAE validation with values ​​of 0.08761, 0.09252, and 0.09288. The three recommended input data from the sequence of accuracy values ​​are RGB+LAB without inpaint, RGB with inpaint, and LAB+YCbCr without inpaint.

Abstract

The distribution of Financial Aid for Underprivileged Students is considered not to be on target due to the unmeasured selection process. So a decision-making system is needed that can select beneficiaries objectively. This research was conducted to assist the school in determining students who deserve this assistance. The purpose of this research is to build a decision-making system for selecting beneficiaries from poor students by applying the Technique for Order of Preference by Similarity to Ideal Solution method. The formulation of the problem is how to build a decision support system using the Technique for Order of Preference by Similarity to Ideal Solution method in selecting students who receive financial aid for underprivileged students. The method used goes through several stages, namely: determining alternatives and criteria, building a normalized decision matrix, building a weighted normalized decision matrix, determining positive and negative ideal solutions, determining the distance between ideal solutions, and determining preference values. There are 7 criteria used, namely social protection card recipients, total income, number of dependents, parental status, distance, class, and report card scores. The results showed that the highest preference value for each alternative was in alternative A3, with a score of 0.6665. While the lowest preference value is in alternative A20 with a score of 0.0719, From the results of the study, it was concluded that the Technique for Order of Preference by Similarity to Ideal Solution method can be used in making decisions on the selection of beneficiaries of poor students based on preference value rankings.
