The development of science and information technology over time is very rapid in today's era, one of which is the agricultural sector. In the agricultural sector, there are many things that utilize technology, such as shallot cultivation. The need for shallots is very high, so many farmers plant shallots. To produce shallots of good quality and have a high selling price, farmers provide nutrition for the shallots they plant. The nutrient that onions really need is urea fertilizer. The fluctuating need for fertilizer for each farmer results in the availability of fertilizer in Kiosks often experiencing shortages. This has an impact on the scarcity of the availability of urea fertilizer. So this research was carried out to predict the level of sales of urea fertilizer in maintaining the need for fertilizer for shallot plants at Kiosk Pak De. Fertilizer availability aims to prepare stocks to avoid scarcity at a later time. The method used in this study is the Monte Carlo Method. This method is a method that can predict based on repeated random sampling. This method can also be used in various aspects of imputation systems and prediction of missing data. The data used in this study are sales data for urea fertilizer from 2020 to 2021. Sales data for 2020 are used to predict sales for 2021 and sales data for 2021 are used to predict sales for 2022. The results obtained from this study are the prediction rate for in 2020 with an accuracy rate of 92% and an accuracy in 2021 of 92.25%. From these results it can be concluded that this method can help Kios Pak De in maintaining scarcity in the sale of urea fertilizer

Dalam penentuan penerima beasiswa di Universitas Adzkia ada beberapa kriteria yang harus tercapai supaya beasiswa yang diberikan tepat sasaran dan kuota terpenuhi. Dalam proses penyeleksian kriteria dan persyaratan calon penerima beasiswa ketelitian penilai menentukan layak atau tidaknya calon penerima beasiswa mendapatkan beasiswanya. Karena banyaknya jumlah peserta yang ikut serta dalam mengajukan beasiswa dan indikator kriteria yang banyak, mengakibatkan team penilai membutuhkan waktu yang cukup lama didalam pemrosesan dan pengambilan keputusan, ditambah lagi tidak adanya metode standar sistematis yang dipakai untuk penilaian kelayakan dalam proses penerimaan beasiswa. Sehingga dibutuhkan suatu metode yang bisa membantu dalam pemrosesan seleksi dan pengambilan keputusan, metode yang di pilih dalam penelitian ini adalah metode SAW (Simple adaptive Weighting), metode ini dikenal karna merupakan metode dengan penjumlahan hasil terbobotan berdasarkan alternatif dan kriteria yang ada sehingga membentuk perengkingan dari semua atribut. Tujuan penelitian ini membantu dalam mengoptimalkan proses seleksi penerimaan beasiswa serta meminimalkan waktu dan tenaga yang diperlukan oleh tim penilai. Hasil dari penelitian ini terbentuklah perangkingan nilai peserta dari yang terbesar ke yang terkecil yaitu artelnatif ke-4 memperloreh rangking 1 dengan total nilai 0,689 dan nilai terendah diperoleh oleh alternatif ke-9 dengan total nilai 0,410, sehingga penelitian ini bisa menjadi bahan rujukan bagi universitas dalam menentukan keputusan siapa yang layak dalam penerimaan beasiswa Adzkia Unggul

The simulation of predicting student arrivals for training is an estimate of the calculation of the arrival rate of students in a period to conduct training. The number of student visits is too many, sometimes inversely proportional to the programmers who carry out learning, this causes the ongoing service to be less than optimal. This study aims to predict student arrivals in the future better. The data processed in this study were 3 periods sourced from the administration of a private company in West Sumatra. The data will be processed and calculated using the Monte Carlo method. The data were tested with various possible elements using a random sample. A powerful numerical calculation tool by simulating statistical data, this simulation obtains accurate values accurately from the physical form of the system that can be observed. The calculation implementation will be developed using an application-based system that will be built with the Hypertext Preprocessor (PHP) programming language. The system developed is easier and more relevant by applying Information Technology. The results obtained in predicting are 80% for 2017 and 84% for 2018. From the results of 80% accuracy in 2017 and 84% 2018 the system works very well to implement. Based on the results of data processing with the Monte Carlo method, it can be predicted that the number of student arrivals for training, as well as a good and fast decision-making process in the future.

This study aims to address issues in the scholarship recipient selection process in vocational high schools (SMK). The main challenge lies in the limited availability of scholarship, necessitating careful selection. The objective of this study is to implement the Simple Additive Weighting (SAW) method as a solution to enhance the structure, efficiency, and objectivity of the selection process. The SAW method is used as the primary approach, which involves steps such as determining the criteria, assigning preference weights, and ranking alternatives. The data used included a sample of five scholarship candidates from SMK N 1 Hiliran Gumanti, with the criteria divided into benefits and costs. The results of the selection of scholarships demonstrate the success of SAW in providing rankings according to predefined criteria. This research highlights the effectiveness of the SAW method in delivering objective rankings to scholarship candidates. The final results can help the selection team to determine the best scholarship recipients. The implementation of SAW is expected to create a more structured and efficient selection system at the SMK, opening opportunities for improved educational access for financially needy students.

Market product reviews are invaluable information if processed carefully. The process of analyzing product reviews is more than just considering star ratings; Comprehensive examination of the overall content of review comments is essential to extracting the nuances of meaning conveyed by the reviewer. The problem currently occurring in analyzing reviews of product purchases in the marketplace is the large number of abbreviations and non-standard language used by commenters, making it difficult for the system to understand. Therefore, a Natural Language Processing (NLP) approach is needed to improve the language in the content of review comments so as to achieve maximum performance in sentiment analysis. This research utilizes the KNN and TF-IDF algorithms, coupled with NLP techniques, to categorize Muslim fashion product reviews into two different groups that is positive and negative. The NLP-enhanced classification achieved 76.92% accuracy, 80.00% precision, and 74.07% recall, surpassing the results obtained without NLP, which had 69.23% accuracy, 80.00% precision, and 64.52 recall. %. Frequently appearing words in reviews serve as a description of collective buyer sentiment regarding the product. Positive reviews indicate customer satisfaction with the quality, speed of delivery, and price of the goods, while negative reviews indicate dissatisfaction with factors such as color differences and differences in the number of items received.
