Abstract

Detecting abusive language on Twitter is an important step in reducing the prevalence of negative content and harassment. This study aims to improve the accuracy and effectiveness of abusive language detection on Twitter by addressing the limitations of the single model commonly used previously. The stacking method is employed by combining Term Frequency-Inverse Document Frequency (TF-IDF) as the feature extraction method, along with the Naive Bayes and XGBoost algorithms as classification models. Naive Bayes is known for its simplicity in handling text classification, while XGBoost excels in processing complex data and achieving high accuracy. The combination of these two models is expected to improve performance in detecting coarse language. The research results show that the proposed model outperforms the methods in previous studies, with an accuracy of 91.91% and an AUC of 96.76%. These findings demonstrate the effectiveness of the stacking approach in reducing classification errors in coarse language detection. Further research could explore the use of larger datasets or more complex models to improve detection accuracy.

Abstract

Stroke due to cerebral ischemia is one of the leading causes of disability worldwide. Animal models of cerebral ischemia that is often used is Global Cerebral Ischemia (GCI). In GCI, the hippocampus is the most susceptible to neuronal cell death. Complications that occur after ischemia are due to increased oxidative stress. Some compounds in purwoceng are reported to have antioxidant activity which oxidative stress have not been studied in the GCI model stroke. This study aims to examine the effect of purwoceng extract on a stroke model (GCI) as a neuroprotective agent in the prevention of stroke complications that have not been previously studied. 25 rats with a stroke model were given purwoceng root extract with 3 doses (20, 30, and 40mg/kg BW) orally for three days. The mice were then tested for memory with the Morriz Water Maze (MWM) test; then histopathological analysis of pyramidal cells in the hippocampus and the expression of SOD1 and SOD2 genes was analyzed using RT-PCR. The MWM test showed that the memory results at the dose of 20mg/kg BW were better than that of the GCI group (p=0.0384), and the PCR of SOD2 showed improvement at the dose of 20mg/kg BW (p=0.0171). No significant difference in histopathological analysis and SOD1 mRNA expression across group. The administration of purwoceng root extract at a dose of 20 mg/kg BW had the effect of improving memory and SOD2 expression in GCI model rats

Abstract

Penelitian ini berjudul “Pengaruh Brand Ambassador Terhadap Peningkatan Brand Awareness Pada Produk Hanasui”. Tujuan dari penelitian ini yakni untuk mengetahui seberapa besar pengaruh dari artis Ranty Maria sebagai brand ambassador hanasui terhadap peningkatan brand awareness. Pada penelitian ini menggunakan teori Kredibilitas sumber, di mana teori ini menjelaskan tentang bahwa seseorang akan lebih mudah dibujuk (persuasi) jika sumbernya persuasinya cukup kredibel. Menurut teori kredibilitas sumber jika semakin tinggi kredibilitas dari seorang komunikator maka semakin besar juga kemungkinan untuk mempengaruhi khalayak. Paradigma yang digunakan pada penelitian ini yaitu paradigma positivisme dengan metode penelitian kuantitatif. Peneliti menggunakan teknik pengumpulan data yang dilakukan melalui kuesioner/angket dan teknik analisis data menggunakan skala Likert. Populasi yang digunakan dalam penelitian ini merupakan masyarakat di Kelurahan Periuk Jaya pada remaja akhir berusia rata rata 15 – 24 tahun. Penelitian ini dilakukan dengan menggunakan rumus perhitungan Slovin sehingga diperoleh sampel sebanyak 98 responden dengan nilai presisi sebesar 10%. Pengambilan sampling ini dilakukan dengan teknik Purposive Sampling. Penelitian ini menggunakan metode SEM-PLS (Partial Least Square) dengan menggunakan software SmartPLS versi 4.0. Hasil penelitian ini menunjukkan bahwa terdapat pengaruh positif signifikan brand ambassador terhadap brand awareness.
Klasifikasi Pengaduan Kekerasan Berbasis Bidirectional Encoder Representations from Transformers (BERT) pada Kementrian Pemberdayaan Perempuan dan Perlindungan Anak Kementrian (PPPA) Jundi, Muhammad; Rahmaddeni; Utami, Putri; Perdana Arifin, Satria; Sinaga, Leonardo

Abstract

Kekerasan terhadap perempuan dan anak merupakan isu serius di Indonesia, dengan ribuan laporan masuk setiap tahun ke lembaga perlindungan. Sebagian besar laporan disampaikan dalam bentuk narasi bebas, yang menyulitkan proses identifikasi jenis kekerasan dan respon yang cepat. Penelitian ini mengembangkan model klasifikasi otomatis berbasis IndoBERT untuk mendeteksi jenis kekerasan dan sentimen pelapor secara simultan. Model dilatih menggunakan pendekatan multi-task learning dengan dua label keluaran: kategori kekerasan (multi-label) dan sentimen (biner). Dataset terdiri dari laporan berbahasa Indonesia yang telah dianotasi manual. Evaluasi dilakukan pada data uji (20%) menggunakan metrik F1-score, precision, dan recall. Hasil menunjukkan bahwa model mencapai F1-score sebesar 0,8528 untuk klasifikasi kekerasan dan 0,8375 untuk sentimen. Pengujian pada narasi fiktif juga membuktikan ketepatan model dalam menangkap konteks semantik dan ekspresi emosional pelapor. Model ini menunjukkan potensi signifikan untuk mendukung lembaga pemerintah dalam mempercepat analisis dan tindak lanjut laporan kekerasan secara digital.

Abstract

Background: Anthrax remains a persistent zoonotic disease in Indonesia, with recurrent outbreaks reported in endemic provinces such as Yogyakarta, Gorontalo, Central Java, and East Nusa Tenggara. Outbreak control is further challenged by the circulation of misinformation, which shapes community perceptions and undermines prevention efforts. Digital epidemiology offers opportunities to complement conventional surveillance by capturing public information-seeking behavior, yet its application in anthrax research in Indonesia remains limited. Methods: This study analyzed temporal and spatial dynamics of public interest in anthrax using Google Trends data from January 2014 to December 2024. Two search terms, antraks (Indonesian) and anthrax (English), were examined to assess monthly patterns, regional distribution, and related search queries. Descriptive analyses were performed to identify peaks of interest, geographic differences, and themes of related and rising queries. Results: Overall search activity was low and stable throughout the 11 years, with distinct peaks corresponding to outbreaks, most notably in July 2023 during the Yogyakarta outbreak. Regional analysis revealed Yogyakarta and Gorontalo as the dominant provinces of search activity. Linguistic patterns showed that antraks was more widely used in western Indonesia, while anthrax was relatively more frequent in eastern provinces. Related queries reflected demand for basic knowledge of symptoms, transmission, and prevention, while rising queries aligned with outbreak-related events. Conclusion: Online search patterns mirror epidemiological risk, cultural context, and digital access. Infodemiology provides timely insights that may enhance outbreak preparedness and risk communication. Integrating digital surveillance with conventional monitoring can support more effective and locally relevant health education strategies for anthrax control in Indonesia.
