Optimalisasi Pengelolaan Inventaris Melalui Aplikasi Berbasis Website pada SMK Negeri 1 Bintan Timur

SMK Negeri 1 Bintan Timur is a vocational high school under the auspices of the Bintan District Education Office. The process of recording inventory items for facilities, infrastructure, and books at SMK Negeri 1 Bintan Timur is done manually by recording them in books. This manual recording process has resulted in several problems, such as lengthy inventory data retrieval processes and the risk of lost records. The system proposed in this study can record the borrowing and returning of inventory items for facilities, infrastructure, and books in the library. This system can assist in the inventory data recording process to minimize the risk of recording errors and data los

ANALISIS KESTABILAN MODEL PENYEBARAN RUMOR MELALUI TWITTER DI INDONESIA

Rumor merupakan bentuk penyebaran informasi dan komunikasi sosial yang dapat membentuk opini publik serta mempengaruhi kepercayaan individu yang mengarah pada perubahan sikap individu terhadap aspek ekonomi, politik, dan sosial. Rumor juga merupakan kebenaran yang belum bisa dikon�rmasi dan berdampak negatif bagi masyarakat, meskipun intervensi dapat dilakukan untuk meminimalkan dampak negatifnya. Oleh karena itu, memahami penyebaran rumor sangatlah penting untuk mendapatkan informasi ilmiah dan strategi yang lebih baik dalam mengurangi dampak negatifnya. Twitter menjadi media penyebaran berita gosip, rumor atau hoax secara spasial dan kronologi karena memiliki struktur komunitas yang unik. Berita terpopuler di Indonesia berdasarkan Getdaytrends Twitter pada tahun 2021 adalah #SahkanRUUPKS. Penelitian ini membahas model penyebaran rumor dengan mempertimbangkan kredibilitas rumor, korelasi rumor dengan kehidupan dan klasi�kasi kelompok berdasarkan kepribadian. Perilaku solusi dari model dianalisis melalui analisis kestabilan di sekitar titik kesetimbangan bebas rumor dan titik kesetimbangan endemik penyebaran rumor. Kestabilan tersebut juga dikaitkan dengan bilangan reproduksi dasar yang menandakan apakah rumor akan menghilang atau menyebar dalam populasi. Hasil analitik dikon�rmasi dengan data aktual dari Twitter di Indonesia dengan SahkanRUUPKS. Implementasi model penyebaran rumor pada data aktual dari Twitter di Indonesia dengan #SahkanRUUPKS menyimpulkan bahwa basic reproduction number R0 < 1 artinya jumlah penyebar tidak meningkat dan berita tentang #SahkanRUUPKS akan memudar dan dilupakan atau #SahkanRUUPKS tidak menyebar dalam populasi

Analisis Komparasi Cybercrime Web Defacement dan Darknet Exposure di Indonesia (Studi Kasus : Lanskap Keamanan Siber di Indonesia Tahun 2022 dan Tahun 2023)

This study aims to analyze the comparison of cyber incidents involving Web Defacement&nbsp;&nbsp;&nbsp; and Darknet Exposure &nbsp;in Indonesia for the years 2022 and 2023, and to evaluate the effectiveness of the mitigation recommendations provided. The method used in this study is the Wilcoxon statistical test to determine significant differences between the incident rates in those two years. The Wilcoxon test results indicate that the Asymp. Sig. (2-tailed) value is 0.008, which, in the case of a one-tailed test, results in a probability of 0.004. This value indicates a significant difference between the Darknet Exposure &nbsp;incident rates in 2022 and 2023. The analysis also suggests that the mitigation recommendations implemented in 2022 were not effective in reducing Darknet Exposure &nbsp;incidents in 2023, as evidenced by an increase in the number of cases. Conversely, for Web Defacement&nbsp; incidents, the Wilcoxon test results show the same Asymp. Sig. (2-tailed) value of 0.008, resulting in a probability of 0.004. This indicates a significant difference between the Web Defacement&nbsp;&nbsp;&nbsp; incident rates in 2022 and 2023. Based on the test results, the mitigation recommendations proved effective in reducing Web Defacement&nbsp; incidents, with a decrease in the number of cases in 2023. From these findings, it can be concluded that cyber incident handling strategies need to be adjusted and strengthened, especially in dealing with Darknet Exposure &nbsp;incidents. Continuous monitoring and evaluation are also crucial for improving the effectiveness of cyber incident management in Indonesia

DYNAMICS OF THE RUMOR SPREADING MODEL OF INDONESIA TWITTER CASE

The study of the spreading of a rumor is significantly important to obtain scientific information and better strategies in reducing its negative impact. Twitter has become a medium for spreading rumors or hoaxes spatially and chronologically because it has a unique community structure. This study demonstrates the model of spreading rumors by considering credibility, correlation, and mass classification based on personality is discussed. The behavior of a model solution around equilibrium points is investigated with the Jacobian matrices. The stability also corresponds to a threshold number indicating the rumor fades away or continues to spread in the population. The analytical results are confirmed by actual data from Twitter in Indonesia with #SahkanRUUPKS. The simulation results show that the free rumor equilibrium point is stable and the threshold number is less than 1. Our study shows that the number of spreaders does not increase and the #SahkanRUUPKS rumor will vanish

Stability Analysis Of The Rumor Spreading Model

The process of spreading rumors is the same as the process of spreading infectious diseases. In this case, a rumor-spreading model is discussed in this study by considering the credibility of rumors, the correlation between rumors and lives, and the classification of groups based on personality. Furthermore, the stability of the model is analyzed for the rumor-free equilibrium point and the rumor-spreading endemic equilibrium point

Development of IoT-based Automatic Water Drainage System on Fishing Boat to Improve Operational Efficiency

The profession of fishermen requires a reliable system to remove stagnant water from fishing boats, as manual drainage is time-consuming and inefficient. This study proposes an IoT-based automatic water drainage system without using an inverter or ultrasonic sensor, offering a cost-effective alternative. The system utilizes a water level sensor and a DC water pump, controlled via a smartphone application. The research model used is the Research and Development (R&amp;D) model, through several stages, namely potential and problems, initial data needs, prototype creation, prototype validation, prototype revision, validation, implementation. Problems occur at the prototype stage, problems that must be revised include aspects of wiring, Power Suitability, Water Level Sensor Test, and the configuration of the relay used. The IOT-based automatic water drainage system can function based on the results of white-box testing including Hardware Implementation, Software Implementation, Implementation of Application Usage, and Automatic Drainage System Testing. This is indicated by the results of the Liquid Water Level Sensor Functionality test, DC Water Pump Functionality Test, Solar Panel and Battery Functionality Test, and IOT Functionality Test. IOT-based automatic water discharge systems on fishing boats are more efficient and cost-effective in the long run, although diesel engines offer more reliability under adverse weather conditions or in places with limited access to sunlight

Involvement of the Wbp pathway in the biosynthesis of Porphyromonas gingivalis lipopolysaccharide with anionic polysaccharide

The periodontal pathogen Porphyromonas gingivalis has two different lipopolysaccharide (LPS) molecules, O-LPS and A-LPS. We have recently shown that P. gingivalis strain HG66 lacks A-LPS. Here, we found that introduction of a wild-type wbpB gene into strain HG66 restored formation of A-LPS. Sequencing of the wbpB gene from strain HG66 revealed the presence of a nonsense mutation in the gene. The wbpB gene product is a member of the Wbp pathway, which plays a role in the synthesis of UDP-ManNAc(3NAc)A in Pseudomonas aeruginosa; UDP-ManNAc(3NAc)A is sequentially synthesized by the WbpA, WbpB, WbpE, WbpD and WbpI proteins. We then determined the effect of the PGN-0002 gene, a wbpD homolog, on the biosynthesis of A-LPS. A PGN-0002-deficient mutant demonstrated an A-LPS biosynthesis deficiency. Taken together with previous studies, the present results suggest that the final product synthesized by the Wbp pathway is one of the sugar substrates necessary for the biosynthesis of A-LPS
