Sumenep is one of the salt-producing regencies in Madura with 27 sub-districts where 11 sub-districts are salt producers which have a total area of 2,077.12 ha of ponds. Generally, people only cultivate salt in certain months because this salt production can only be done and depends on several factors, such as weather and land area. From the existing problems, this research was conducted using a Deep Learning approach, namely Artificial Neural Network (ANN) and Simple Recurrent Neural Network (SimpleRNN) to predict the amount of salt production. Weather data as input and salt production data as output taken from the last 6 years (2017-2022). The accuracy value in model training was used as a comparison to make predictions. the process of dividing training and testing data was also carried out with a ratio of 80%:20%. Furthermore, both methods was given 6 trainings each, so that the training of the two methods produces a different accuracy value. The ANN model produces an accuracy value of 53% and 71% for Simple RNN. Based on the resulting accuracy value, this base cased study is suitable for using the SimpleRNN algorithm model compared to ANN, provided that the amount of data used is large-scale
苏美内普是马都拉的产盐区之一,共有 27 个分区,其中 11 个分区为产盐区,池塘总面积达 2,077.12 公顷。一般情况下,人们只在特定的月份种植盐,因为盐的生产只能在特定的月份进行,并取决于天气和土地面积等多种因素。针对存在的问题,本研究采用深度学习方法,即人工神经网络(ANN)和简单循环神经网络(SimpleRNN)来预测盐产量。天气数据作为输入,盐产量数据作为输出,数据取自过去 6 年(2017-2022 年)。模型训练的准确率值被用作预测的比较。训练数据和测试数据的划分过程也以 80%:20% 的比例进行。此外,两种方法各进行了 6 次训练,因此两种方法的训练产生了不同的准确度值。ANN 模型的准确率为 53%,而 Simple RNN 的准确率为 71%。根据得出的准确率值,如果使用的数据量较大,那么与 ANN 相比,该基础案例研究适合使用 SimpleRNN 算法模型。

Data collection in research is challenging, especially on Kaggle, a popular platform for data scientists. However, in recent years, there have been many reports of fake accounts on Kaggle that are difficult to detect, threatening data integrity and research credibility. One of the key traits to identify fake accounts is by looking at incomplete or inconsistent profiles. This research aims to help datascience users to detect Kaggle bot accounts by building a model using Deep Neural Networks. DNN is a machine learning algorithm that mimics the nervous system in the human brain. DNN consists of input layers, hidden layers

Over the past few years, people have been able to get and share information through social media easily. Some of that information can be a false issue created by a buzzer account that intends to influence people into a specific opinion. Politicians often use social media to maintain a good image in society by utilizing buzzer accounts. The main characteristic of a buzzer account is that they upload the same content repeatedly within a certain period. Before analyzing data taken from social media such as Twitter, we need a buzzer detection system to filter data from buzzer users.  This research attempts to build a buzzer detection system using text processing and classification method. We use the similarity of tweets as a feature for the buzzer detection system by applying Cosine Similarity to the Term Frequency - Inverse Document Frequency (TF-IDF) feature of the tweets. In addition, we will use other features such as the number of followers, number of followings, the intensity of tweets, the ratio of retweets, and the ratio of tweets that contain links as additional features in this study. This research uses these features as inputs to the Support Vector Machine model to determine whether an account is a buzzer or not. This system has promising results by having 89% accuracy, 86.67% precision, 70.91 % recall, and 78% F1-score.
在过去的几年里,人们已经能够很容易地通过社交媒体获取和分享信息。其中一些信息可能是由蜂鸣器账户制造的虚假问题,旨在影响人们形成特定的观点。政客们经常利用社交媒体,利用蜂鸣器账号来维护自己在社会中的良好形象。蜂鸣器账号的主要特点是在一定时间内反复上传相同的内容。在分析从Twitter等社交媒体获取的数据之前,我们需要一个蜂鸣器检测系统来过滤蜂鸣器用户的数据。本研究试图利用文本处理和分类的方法构建一个蜂鸣器检测系统。我们将推文的相似度作为蜂鸣器检测系统的一个特征,方法是将余弦相似度应用于推文的词频-逆文档频率(TF-IDF)特征。此外,我们将使用其他特征,如关注者数量、关注者数量、推文强度、转发比例和包含链接的推文比例作为本研究的附加特征。本研究使用这些特征作为支持向量机模型的输入,以确定一个帐户是否是蜂鸣器。该系统具有89%的正确率、86.67%的精密度、70.91%的召回率和78%的f1得分。

Many changes have occurred due to the digitalization of education in Indonesia today, especially in terms of teaching and learning. Many colleges and universities have incorporated digital technology into the educational process, one of which is learning videos. Learning videos can be in the form of class recordings that are uploaded to the internet or tutorial videos made specifically for certain subjects. Learning videos can help students understand material more easily and can be accessed by students anytime and anywhere, thus facilitating the teaching and learning process. User Experience (UX) deals with the emotions, feelings, and thoughts that users experience when using a product or service. UX can be applied to learning videos by focusing on several factors, such as delivering material that is clear and easy to understand. So in this study, a UX assessment was carried out on learning videos. Learning videos using cash and bank material in introductory accounting courses at the diploma level with the concept of motion graphics Motion graphics were chosen because of their flexibility in conveying this information and attracting students' interest. This study consisted of seven processes, including: 1) determining goals and objectives; 2) making scenarios and scripts; 3) equipment preparation; 4) recording; 5) editing; 6) publication; and 7) assessment. In the assessment process, the respondent fills out a questionnaire. The questionnaire consists of 10 questions with aspects of use (usefulness, satisfaction, and ease of use). The value of each question in the questionnaire ranges from 1 to 4, with the following conditions: 1) bad; 2) enough; 3) good; and 4) very good. Every day for seven days, ten different people responded. As a result of filling out the questionnaire, a fluctuating curve was obtained.
由于印度尼西亚今天的教育数字化,特别是在教学和学习方面发生了许多变化。许多学院和大学已经将数字技术纳入教育过程,其中之一就是学习视频。学习视频可以是上传到互联网上的课堂录音,也可以是专门为某些科目制作的教程视频。学习视频可以帮助学生更容易地理解材料,并且学生可以随时随地访问,从而方便了教学过程。用户体验(UX)处理用户在使用产品或服务时所经历的情感、感觉和想法。用户体验可以通过关注几个因素来应用于学习视频,比如提供清晰易懂的材料。因此在本研究中,我们对学习视频进行了用户体验评估。在文凭级别的会计入门课程中使用现金和银行材料的学习视频与动态图形的概念选择动态图形是因为它们在传达信息和吸引学生兴趣方面具有灵活性。本研究包括七个过程,包括:1)确定目标和目的;2)制作场景和剧本;3)设备准备;4)记录;5)编辑;6)出版;7)评估。在评估过程中,被调查者填写一份问卷。问卷由10个问题组成,包括使用方面(有用性、满意度和易用性)。问卷中每个问题的取值范围为1 - 4,有以下情况:1)差;2)足够;3)良好的;而且非常好。七天的每一天,都有十个不同的人回应。通过问卷的填写,得到了一条波动曲线。

Many colleges and universities have incorporated digital technology into the educational process, one of which is learning videos. Learning videos can be in the form of class recordings that are uploaded to the internet or tutorial videos made specifically for certain subjects. Learning videos can help students understand material more easily and can be accessed by students anytime and anywhere, thus facilitating the teaching and learning process. User Experience (UX) deals with the emotions, feelings, and thoughts that users experience when using a product or service. UX can be applied to learning videos by focusing on several factors, such as delivering material that is clear and easy to understand. So in this study, a UX assessment was carried out on learning videos. Learning videos using cash and bank material in introductory accounting courses at the diploma level with the concept of motion graphics Motion graphics were chosen because of their flexibility in conveying this information and attracting students' interest. This study consisted of seven processes, including: 1) determining goals and objectives; 2) making scenarios and scripts; 3) equipment preparation; 4) recording; 5) editing; 6) publication; and 7) assessment. In the assessment process, the respondent fills out a questionnaire. The questionnaire consists of 10 questions with aspects of use (usefulness, satisfaction, and ease of use). The value of each question in the questionnaire ranges from 1 to 4, with the following conditions: 1) bad; 2) enough; 3) good; and 4) very good.

Tujuan penelitian ini untuk menerapkan sebuah algoritma pada sebuah aplikasi kamus pencarian informasi mengenai sistem manajemen basis data bagi para programmer yang akan mempelajari mengenai konsep dari Da-ta Base Management System (DBMS). Aplikasi tersebut menggunakan sebuah algoritma brute force, dimana algo-ritma tersebut digunakan untuk melakukan pencarian antara pola dan teks pada sebuah aplikasi pencarian ber-basis web. Metode penelitian yang digunakan adalah kombinasi antara metode penelitian kuantitatif dan kuali-tatif, sedangkan pengembangan perangkat lunak menggunakan pendekatan prototype. Hasil penelitian ini adalah sebuah algoritma brute force yang dapat digunakan untuk menyelesaikan masalah pencarian kamus istilah DBMS dengan sederhana, mudah dipahami dalam penerapannya, lebih efektif untuk data yang terbatas, source code yang dihasilkan sedikit dan menghasilkan algoritma yang dapat dieksekusi untuk beberapa masalah seperti pen-cocokan dan pencarian.
