Abstract

Films are growing rapidly thanks to the increasing number of internet users. According to USC (University of Southern California), users easily get bored if they cannot find the movie they want within 1.5 minutes or within 90 seconds and may switch to other platforms, resulting in a decrease in active users. This problem can be overcome by using a recommendation system that can provide film recommendations based on user ratings. In this design, the recommendation system used is Neural Collaborative Filtering (NCF). Testing using 3,235 film titles, 610 users, and 87,812 ratings produced the best scenario with a recall value of 69.6% and Normalized Discounted Cumulative Gain (NDCG) with a value of 81.4%. From the test results, it can be concluded that 69.6% of films that should have been recommended were successfully recommended, and the recommendation position was similar to the actual position in 81.4% of cases.

Abstract

Tourism is a crucial sector in the economy of a region, and the use of digital technology in the tourism industry is steadily increasing. The responsiveness of a tourism website is a key factor influencing users' perceptions and experiences with the Beyondsultra website. Beyondsultra is a tourism website for Southeast Sulawesi created by the City of Kendari Regional-Owned Enterprise. The research aims to identify the responsiveness of the Beyondsultra website in influencing user perceptions of the quality of their user experience and to provide appropriate recommendations for the company to enhance user satisfaction with the Beyondsultra website. The selected respondents for the study are potential tourists and active users of the Beyondsultra website. Based on data obtained from user satisfaction observations while interacting with the Beyondsultra website using the User Experience Questionnaire (UEQ) and System Usability Scale (SUS) methods, above-average results were obtained for UEQ. Subsequently, a reevaluation was conducted to delve deeper into the issues faced by users, utilizing Cooperative Evaluation techniques. The research findings indicate an improvement in user satisfaction with the Beyondsultra website using the UEQ method, with a 68% increase in attractiveness, 93% in clarity, 91% in efficiency, 100% in stimulation, and 63% in novelty. However, one aspect, precision, remained unchanged after evaluation. In the SUS method, the average assessment score showed a 15% improvement.

Abstract

Pengelolaan sampah merupakan salah satu masalah lingkungan yang perlu ditangani secara serius. Ada dua jenis sampah yaitu sampah organik dan non organik, sampah organik adalah sampah umum yang dapat diuraikan seperti kertas, daun sedangkan sampah non organik ialah sampah yang tidak dapat diuraikan seperti plastik, metal, sampah non organik merupakan sampah yang sangat sulit diuraikan oleh tanah sehingga bila tertimbun dalam waktu yang sangat lama merusak lapisan tanah dan menyebabkan pencemaran tanah, untuk itu Perlu adanya kesadaran dan pengetahuan masyarakat tentang klasifikasi sampah, daur ulang sampah. Salah satu cara untuk mengatasi masalah ini adalah dengan menerapkan sistem deteksi objek real time untuk mengidentifikasi jenis sampah. Pada penelitian ini menggunakan metode YOLOv8 (You Only Look Once) yang akan mendeteksi sampah secara real time dan juga dapat mengklasifikasikan jenis sampah yang ditampilkan pada webcam untuk memisahkan sampah organik dan non organik. Melalui penelitian ini penulis telah membuat sebuah pendeteksi yang mampu memilah sampah organik dan non organik dengan mengandalkan teknologi pengolahan citra memanfaatkan metode YOLOV8. Penulis menggunakan dataset sebanyak 1853 dan 2205 citra yang telah dianotasi dengan kelas plastik, metal dan kardus Dan didapatkan nilai performa jaringan dengan nilai akurasi 94,6 persen, nilai Recall sebesar 94,5 persen dan nilai F-1 Score sebesar 94,6 persen Kata kunci : Sistem Klasifikasi Sampah, Sampah Organik, sampah non organik YOLOV8, IoT

Abstract

The purpose of this study is to ascertain how students at Sukma Medan School of Management use social media in relation to their purchases of beauty goods. Secondary data collection is the research methodology used, and data is gathered via documentation studies. Thirty distinct groups, chosen at random, comprise the study sample. PLS SEM (Partial Least Square – Structural Equation Modelling) software is used in the quantitative descriptive data analysis methodology. The PLS approach is used in the analytic strategy, along with inner and outer model analyses. The research results indicate a positive and substantial impact of social media on consumer choices to purchase. This is evident from all tested social media variables using SmartPLS, which yield positive results. The strong R-squared value of 0.717 indicates that social media has a 71.7% influence on the purchase decision variable. Additionally, factors unrelated to the investigated variable have an impact on other aspects.

Abstract

This study explores the integration of fossil and renewable energy generators on Selayar Island, focusing on optimizing Diesel Power Plants (PLTD) and Solar Power Plants (PLTS). Using Mixed-Integer Linear Programming (MILP) for generator scheduling, simulations reveal that a 15% rotational backup constraint positively impacts operational costs and system reliability. The findings provide practical recommendations for operators to enhance efficiency, reduce costs, and improve overall system reliability in the context of hybrid energy systems.

Abstract

In the Dynamic Economic Dispatch (DED) based on Mixed Integer Linear Programming (MILP) for the electricity of Sumbawa Island by considering RE (Renewable Energy) power plants, several aspects need to be considered, namely Variable Addition and Limitations: In the MILP model, the new variable must include the allocation of power from RE sources, such as solar power plants or geothermal power plants. Relevant technical and operational constraints should also be applied, such as capacity limits, characteristic curves and sustainability limits for renewable energy sources. The Sumbawa Island electricity system must consider the technical limitations related to RE Power plants. This includes capacity limitations, sustainability limitations (such as solar radiation levels or water discharge during the dry season), as well as the system's ability to handle variations in power generated by RE Power plants that depend on natural energy sources. One of the challenges in integrating RE Power plants is its variability. Renewable energy sources such as solar and hydropower tend to fluctuate in their power output depending on weather conditions. Therefore, the DED model must consider predictions or estimates of the power generated by RE Power plants to optimize accurate power allocation and minimize operational costs. The simulation results show that the Mixed Integer Linear Programming (MILP) method is able to provide a simple and economical solution to the DED problem. The change in operation using gas fuel and cofiring by 5% is a factor in the existence of minimal fixed power in the system. This thesis is a DED solution using Mixed Integer Linear Programming (MILP) by considering fuel changes as the main consideration in mathematical calculations to determine plant operation. With the change in PLTMG fuel type from B35 to gas, total generation costs decreased by 10.89%. With the change in PLTMG fuel type from B35 to gas and PLTU cofiring by 5%, total generation costs decreased by 10.94%.

Abstract

Solusi keamanan data telah memimpin kemajuan teknis. Kriptografi dan steganografi adalah dua dari beberapa bidang ilmu yang telah mengembangkan teknik ini untuk melindungi data sensitif. Keamanan data memerlukan seperangkat alat, bukan solusi tunggal. Tujuan utama penelitian ini adalah menggunakan algoritma Advanced Encryption Standard (AES) dan kriptografi untuk mengamankan percakapan teks, fail dokumen, beserta isinya. AES adalah metode kriptografi yang efektif. Data dapat dienkripsi dan didekripsi menggunakan blok ciphertext simetris. Pengguna dapat mengenkripsi SMS, menyimpannya dalam dokumen terenkripsi, mengenkripsi konten dokumen, dan mengompresnya, sesuai dengan analisis data. Untuk menjamin perlindungan data melalui keamanan dan enkripsi, hasil enkripsi fail dokumen disembunyikan dalam sebuah gambar. Kata kunci : Kriptografi, Advanced Encryption Standard (AES), Pesan Teks, Isi Fail Dokumen, Steganografi.
