Abstract

With the advancement of information and communication technology, it has become easier for people to exchange information and access educational content, including through online learning platforms such as Ruangguru. One of Ruangguru's flagship programs is Clash of Champions, which attracts public attention and generates various sentiments on social media. However, analyzing public sentiment towards this program faces challenges, especially due to the imbalance in the amount of data between majority and minority sentiments, which may affect the accuracy of sentiment analysis models. This study aims to compare the performance of two algorithms, namely Naïve Bayes and Support Vector Machine (SVM), in analyzing public sentiment towards this program. Using 5,226 tweets from social media X, the data was balanced using the Synthetic Minority Oversampling Technique (SMOTE) method to overcome the data imbalance problem. After the data was divided into 80% for training and 20% for testing, the results showed that before using SMOTE, Naïve Bayes had an accuracy of 78%, while SVM reached 82%. After SMOTE was applied, Naïve Bayes' accuracy increased to 79%, while SVM rose to 84%. In addition to accuracy, significant improvements were also seen in precision, recall, and f1-score, especially for positive sentiments. The results show that SVM is superior to Naïve Bayes, both in accuracy and other evaluation metrics. This research provides an in-depth understanding of the effectiveness of algorithms in sentiment analysis on entertainment-based educational programs and is expected to be a reference for the development of similar models in the future.

Abstract

Sektor pariwisata adalah sektor yang sangat potensial untuk meningkatkan perekonomian nasional. Aktivitas ekonomi dalam wisata sangat dipengaruhi oleh preferensi konsumen dalam memilih atraksi wisata. Aktivitas wisata terutama wisata alam menghasilkan layanan jasa lingkungan yang dapat diperhitungkan sebagai nilai ekonomi. Keterbatasan mekanisme pasar untuk mengukur nilai jasa wisata alam menyebabkan jasa wisata cenderung dinilai lebih rendah (undervalue). Tujuan penelitian ini adalah mengidentifikasi pola permintaan wisatawan, mengestimasi nilai ekonomi, menganalisis daya dukung kawasan dan merumuskan strategi dalam mengelola kawasan wisata. Metode yang digunakan yaitu Analisis Deskriptif, Travel Cost Method, Physical Carrying Capacity, Real Carrying Capacity dan Effective Carrying Capatiy, Analasis SWOT dan Quantitative Strategic Planning Matrix (QSPM). Hasil penelitian menunjukkan bahwa wisatawan menilai Agro Eduwisata Organik dalam kondisi baik walaupun terdapat kekurangan pada aspek penilaian kualitas air, fasilitas wisata dan aksesbilitas. Tujuan wisatawan terhadap lokasi wisata yaitu wisatawan mengunjungi untuk menikmati pemandangan/Landscape. Nilai ekonomi wisata di kawasan yaitu sebesar Rp 256.250.000 per tahun. Secara umum daya dukung kawasan Agro Eduwisata Organik Mulyaharja mengalami over carrying capacity pada beberapa atraksi, tetapi pada atraksi lainnya masih under carrying capacity. Strategi yang menjadi prioritas utama yaitu mengevaluasi dan mengembangkan pembangunan objek wisata dengan berkerjasama dengan investor atau pemda. The tourism sector has the potential to improve the national economy. Consumer preferences strongly influence economic activity in tourism when choosing tourist attractions. Tourism activities, especially nature tourism, produce environmental services that can be calculated as economic value. However, the limitations of market mechanisms to measure the value of natural tourism services cause tourism services to tend to be undervalued (undervalued). This study aims to identify patterns of tourist demand, estimate economic value, analyze the area's carrying capacity, and formulate strategies for managing tourist areas. The methods used are Descriptive Analysis, Travel Cost Method, Physical Carrying Capacity, Real Carrying Capacity and Effective Carrying Capacity, SWOT Analysis, and Quantitative Strategic Planning Matrix (QSPM). The results showed that tourists rated Organic Agro Edutourism in good condition despite deficiencies in water quality assessment, tourist facilities, and accessibility. Tourists visit tourist sites to enjoy the scenery/landscape. The economic value in the area is IDR 256,250,000 per year. In general, the carrying capacity of the Mulyaharja Organic Agro-Edutourism area is experiencing over-carrying capacity at some attractions, but other attractions still need to be under-carrying capacity. The strategy that becomes the main priority is evaluating and developing the development of tourist objects in collaboration with investors or local governments.

Abstract

Purpose – This study aims to analyze the effect of brand equity and halal labels on purchase intention toward Wardah cosmetics from an Islamic marketing perspective in the Bogor region. It builds on previous studies that show inconsistent results regarding the role of halal attributes in consumer purchase behavior. By incorporating halal awareness as a moderating variable and applying the SEM-PLS method, this study seeks to clarify these relationships in a local halal cosmetics market. The findings indicate that brand equity and brand image positively influence purchase intention, while halal awareness does not moderate these effects. Design/Methods/Approach – This study employed a quantitative approach using a survey method to collect data from consumers who have purchased Wardah cosmetics in the Bogor region. Data were analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) to examine the relationships between brand equity, brand image, halal awareness, and purchase intention. Findings – The results show that brand equity and brand image have a positive and significant effect on purchase intention. However, halal awareness does not moderate the relationship between brand equity and purchase intention, nor between brand image and purchase intention. These findings indicate that branding factors play a more dominant role than halal awareness in influencing consumers’ purchase intention toward Wardah cosmetics in the Bogor region. Research Implications/Limitations – This study is limited by its focus on a single halal cosmetic brand (Wardah) and a specific geographic area (Bogor), which may restrict the generalizability of the findings to other brands or regions. The use of a cross-sectional survey and self-reported data may also limit the ability to capture changes in consumer behavior over time. Nevertheless, the findings provide practical implications for halal cosmetic marketers by highlighting the greater importance of brand equity and brand image compared to halal awareness in shaping purchase intention within a local Muslim market. Originality/Value – This study adds value to Islamic marketing literature by providing empirical evidence on the relative influence of branding factors and halal awareness on purchase intention in a local halal cosmetics market. By incorporating halal awareness as a moderating variable and focusing on Wardah consumers in Bogor, this research offers a contextual contribution that complements prior studies with mixed findings. Future research may extend this model to different brands, regions, or longitudinal designs to enhance generalizability.
