To avoid citizen disputes, hate speech on social media, such as Twitter, must be automatically detected. The current research in Indonesian Twitter focuses on developing better hate speech detection models. However, there is limited study on the explainability aspects of hate speech detection. The research aims to explain issues that previous researchers have not detailed and attempt to answer the shortcomings of previous researchers. There are 13,169 tweets in the dataset with labels like “hate speech” and “abusive language”. The dataset also provides binary labels on whether hate speech is directed to individual, group, religion, race, physical disability, and gender. In the research, classification is performed by using traditional machine learning models, and the predictions are evaluated using an Explainable AI model, such as Local Interpretable Model-Agnostic Explanations (LIME), to allow users to comprehend why a tweet is regarded as a hateful message. Moreover, models that perform well in classification perceive incorrect words as contributing to hate speech. As a result, such models are unsuitable for deployment in the real world. In the investigation, the combination of XGBoost and logical LIME explanations produces the most logical results. The use of the Explainable AI model highlights the importance of choosing the ideal model while maintaining users’ trust in the deployed model.

Perkembangan teknologi memberikan dampak terhadap kemajuan di segala bidang kehidupan manusia terutama dalam bidang informasi. Hal ini memberikan dampak positif dan negatif. Salah satu dampak positifnya adalah mudahnya bertukar informasi dari yang bersifat umum atau rahasia melalui internet. Dampak negatifnya adalah data yang bersifat rahasia menjadi kurang aman dan dapat disalahgunakan oleh pihak yang tidak berwenang. Kriptografi kurva eliptik El-Gamal (ECC: Eliptic Curve Cryptosystem) memberikan solusi untuk keamanan suatu informasi. ECC merupakan salah satu metode kriptografi kunci publik yang mempunyai tingkat keamanan tinggi dibandingkan dengan algoritma kunci publik lainnya. Tujuan dari penelitian ini adalah memahami konsep kriptografi kurva eliptik El-Gamal yang akan didefinisikan di Galois field prima. Hasil dari penelitian ini, yaitu penggunaan kurva eliptik El-Gamal di Galois field prima untuk proses pembentukan kunci, proses enkripsi dan proses dekripsi pada suatu data dengan menggunakan Python.

Diberikan dan merupakan ring komutatif. Keprimaan pada suatu ring telah mengalami perkembangan ke dalam struktur modul. Namun, definisi keprimaan yang ada selama ini hanya berfokus pada operasi pergandaan skalar di dalam modul. Submodul prima-α merupakan salah satu perumuman dari submodul prima yang melibatkan operasi aditif dan pergandaan skalar di dalam modul. Pada artikel ini disajikan generalisasi dari submodul prima-α ke dalam struktur (R,S)-modul, yang selanjutnya disebut (R,S)-submodul prima-α gabungan. Selanjutnya, disajikan beberapa sifat dari (R,S)-submodul prima-α gabungan. Beberapa sifat tersebut diantaranya adalah syarat perlu dan syarat cukup suatu (R,S)-submodul membentuk (R,S)-submodul prima-α gabungan; sifat (R,S)-submodul prima-α gabungan yang berkaitan dengan homomorfisma (R,S)-modul; serta syarat perlu dan syarat cukup suatu (R,S)-submodul faktor membentuk (R,S)-submodul prima-α gabungan. Beberapa sifat (R,S)-submodul prima-α gabungan tersebut diperoleh dari pengembangan sifat keprimaan dalam struktur modul.

RADIKAL SUPERNILPOTENT BERTINGKAT Puguh Wahyu Prasetyo

The development of Ring Theory motivates the existence of the development of the Radical Theory of Rings. This condition is motivated since there are rings which have properties other than those owned by the set ring of all integers. These rings are collected so that they fulfill certain properties and they are called radical classes of rings. As the development of science about how to separate the properties of radical classes of rings motivates the existence of supernilpotent radical classes. On the other hand, there exists the concept of graded rings. This concept can be generalized into the Radical Theory of Rings. Thus, the properties of the graded supernilpotent radical classes are very interesting to investigate. In this paper, some graded supernilpotent radical of rings are given and their construction will be described. It follows from this construction that the graded Jacobson radical is a graded supernilpotent radical.

The education sector is feeling the impact of the COVID-19 pandemic. During the pandemic, the procedure for teaching and learning activities (TLA) changes according to the circumstances, this greatly affects the level of student learning activity (SLA). The purpose of this study is to improve SLA using the discovery learning mode (DLM) which is accompanied by the TPACK approach in mathematics teaching and learning. The type of research used is classroom action research (CAR), in this CAR it uses two cycles and each cycle has two meetings. This PTK takes the research subject, namely students of class X MIPA 2 SMAN 1 Bantul in the even semester of the 2021/2022 academic year. The results of this CAR show that there is an increase in SLA in mathematics learning using MDL. The increase in the SLA value can be seen from the pre-cycle results with the percentage value of 62.8% increasing to 71.42% after going through the action during the first cycle, then during the second cycle there was an increase with the percentage value of 89.7%. In cycle II, all SLA indicators have reached the desired criteria. The desired SLA criteria are with a minimum score percentage of 75% with high criteria.Keywords: discovery learning, Classroom Action Research, Student Learning Activity

Students' low reading interest greatly affects learning outcomes in Vector Analysis class. This is due to the rare interaction between students and learning resources in class. To increase student activity in reading and understanding the concept of vector analysis material, an e-LKM product is needed. This study aims to develop Student Worksheets (LKM) in electronic form that is integrated with numeracy literacy which can be used for learning vector analysis courses by knowing the validity and practicality of procedures so that the use of these e-LKM can improve students' critical thinking. This development research uses the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). Furthermore, the evaluation stage is carried out at each stage to improve the e-LKM that is made. The subjects were 21 students in semester VI of class C Mathematics Education FKIP Universitas Ahmad Dahlan. The research data was obtained by collecting questionnaires from material experts, media, and students' responses to the practicality of the media being developed. From the results of the questionnaires distributed, the average questionnaire from the two material experts and media experts showed excellent criteria with a mean score of 4.611 and 4.47 respectively. The results of student responses to product use show excellent criteria with a mean score of 4.27. Based on these results, the e-LKM that is used is proven to be valid and practical.

The prediction of project completion time, which is important in project management, is only based on an estimate of three numbers, namely the fastest, slowest, and presumably time. The common practice of applying normal distribution through Monte Carlo simulation in Program Evaluation and Review Technique (PERT) research often fails to accurately represent project activity durations, leading to potentially biased project completion prediction. Based on these problems, a different method is proposed, namely, Discrete Event Simulation (DES). The research aims to evaluate the effectiveness of the simmer package in R in conducting PERT analysis. Specifically, there are three objectives in the research: 1) develop a simulation model to predict how long a project will take and find the critical path, 2) create an R script to simulate discrete events on a PERT network, and 3) explore the simulation output using the simmer package in the form of summary statistics and estimation of project risk. Then, a library research with a descriptive and exploratory method is used for data collection. The hypothetical network is used to obtain the numerical results, which provide the predicted value of the project completion, the critical path, and the risk level. Simulation, including 100 replications, results in a predicted project completion time and a standard deviation of 20.7 and 2.2 weeks, respectively. The DES method has been proven highly effective in predicting the completion time of a project described by the PERT network. In addition, it offers increased flexibility.
