Sentiment Analysis of Hotel Reviews in Senggigi using Decision Tree and Support Vector Machine Algorithm
Full text linkThe tourism industry is a rapidly growing sector that significantly contributes to the economy, including Indonesia. One of the popular tourist destinations in Indonesia is Senggigi, located on the island of Lombok. This destination offers high natural and cultural appeal. In the tourism industry, hotels are crucial as primary accommodations for travelers to stay and rest. Tourist reviews on hotel services greatly influence potential visitor’s decisions in selecting the right accommodation. Therefore, sentiment analysis of hotel reviews is essential for understanding customer satisfaction levels and assisting hotel managers in improving service quality. This research applies a comparative quantitative approach using Decision Tree and Support Vector Machine (SVM) algorithms. The dataset consists of 6,920 hotel reviews collected from TripAdvisor platforms through web scraping techniques. Data preprocessing included data cleaning, case folding, tokenization, stop word removal, and stemming to enhance classification performance. Sentiment labels were categorized into positive, neutral, and negative classes. Model performance was evaluated using multiple metrics, including accuracy, precision, recall, and F1-score, to ensure a comprehensive assessment. The word frequency distribution reveals that that accommodation experience and room quality play a crucial role in customer satisfaction. Positive sentiment is dominated by adjectives like great, nice, and beautiful, reflecting pleasant experiences. Negative sentiment is expressed more politely through phrases such as not good or not very nice. Neutral sentiment tends to be descriptive without strong emotional expression. In terms of model performance, SVM outperformed the Decision Tree model, achieving an accuracy of 90%, precision of 91%, recall of 90%, and an F1-score of 85%. In comparison, the Decision Tree achieved an accuracy of 87%, precision of 84%, recall of 87%, and an F1-score of 85%. These findings demonstrate the superior capability of SVM in handling complex and diverse textual data. This study contributes academically by strengthening empirical evidence on the effectiveness of machine learning–based sentiment analysis in the tourism domain and practically by providing actionable insights for hotel managers to improve service quality and customer satisfaction

Analisis Hubungan Kepatuhan Suplementasi Tablet Besi Dengan Karakteristik Ibu Melahirkan Bayi Berat Badan Lahir Rendah di RSUD Wonosari Yogyakarta
Full text linkLow birth weight (LBW) is a leading cause of neonatal mortality, especially in developing countries. Previous studies have not comprehensively assessed the role of maternal adherence to iron tablet consumption, gestational age, maternal age, and anemia status. This study aims to analyze the relationship between adherence to iron tablet consumption and the characteristics of mothers who gave birth LBW at Wonosari Regional Hospital, Yogyakarta. This is a retrospective analytical study with a cross-sectional design on 47 pregnant women who gave birth LBW between October 2024 and March 2025. Data collection involved the use of an adherence questionnaire to assess adherence to iron supplementation, as well as secondary data obtained from patient medical records. Statistical analysis was performed using the chi-square test to determine the relationship between variables. The results showed no statistically significant association between adherence to iron supplementation (p=0.74), maternal age (p=0.34), or anemia status (p=0.36) with LBW. However, there was a strong and statistically significant association between gestational age and LBW (p < 0.001), which showed that preterm birth is a major risk factor for LBW. In conclusion, gestational age was significantly associated with LBW, while adherence to iron supplementation, maternal age, and anemia status were not. Preventing preterm birth should be a primary focus in strategies aimed at reducing the incidence of LBW
Pengaruh E-book DAGUSIBU Terhadap Pengetahuan dan Perilaku Swamedikasi Obat Pada Anggota Pemberdayaan Kesejahteraan Keluarga
Full text linkInappropriate use of medicines, whether prescribed by physicians or used for self-medication, poses a risk of medication errors and threatens patient safety. One of the contributing factors is the low level of public literacy in proper drug management based on the DAGUSIBU principles (Obtain, Use, Store, and Dispose). This study aimed to determine the effect of the DAGUSIBU e-book on improving knowledge and self-medication behavior among members of the PKK in Banjar Sigaran, Desa Sedang. This research employed a pre-experimental method with a one-group pretest–posttest design involving 50 respondents selected using a consecutive sampling technique. The research instruments consisted of knowledge and behavior questionnaires based on the DAGUSIBU concept and the Theory of Planned Behavior (TPB). The majority of respondents were aged 36–45 years (40%), had a secondary level of education (58%), were housewives, and had an income below the regional minimum wage (44%). The Wilcoxon test was applied because the data were ordinal and not normally distributed. The results indicated an improvement in the knowledge category from poor (62%) to moderate (62%) and a change in behavior from negative (52%) to positive (60%) after the intervention. A significant effect was found between the use of the e-book and the levels of knowledge and self-medication behavior (p-value < 0.001). In conclusion, the DAGUSIBU e-book as a digital educational medium is proven to have a significant effect in supporting the improvement of drug management literacy at the household level

Eksplorasi Potensi Antibakteri Senyawa Xanton Dalam Garcinia mangostana L. : Review
Full text linkXanthone compounds are a group of secondary metabolites commonly found in Garcinia mangostana plants. Several studies have shown that the content of these compounds in mangosteen plants exhibits antibacterial activity against both Gram-positive and Gram-negative bacteria. This review aims to summarize various findings related to the antibacterial activity of mangosteen, both in extract form and pure xanthone compounds, as well as their mechanisms. A comprehensive literature search was conducted through PubMed, Mendeley, and Google Scholar databases using relevant keywords. Articles that met the inclusion criteria were reviewed to identify findings related to mangosteen's antibacterial activity. The results showed that several mangosteen extracts with different solvents, such as ethanol, methanol, and n-hexane, exhibited different metabolite profiles and activities against Gram-positive and Gram-negative bacteria, including Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. Among the various xanthone compounds, α-mangostin is the most extensively studied and has shown potential antibacterial activity, although other xanthone metabolites may exhibit similar activity. The antibacterial mechanisms of this compound include membrane damage, increased permeability, and inhibition of biochemical pathways for growth. In conclusion, xanthone compounds have great potential as natural antibacterial candidates, but the exploration of specific metabolites is still limited to α-mangostin, highlighting the need for further exploration of xanthone metabolites and their relationship with antibacterial activity
EFFECT OF GLYCEROL CONCENTRATION VARIATIONS ON THE CHARACTERISTICS OF EDIBLE FILM MADE FROM KEPOK BANANA (Musa Paradisiaca) PEEL
Full text linkThe increasing accumulation of synthetic plastic waste has become a major environmental concern, necessitating the development of environmentally friendly packaging alternatives, such as edible films. This approach contributes to the advancement of sustainable food packaging while simultaneously enhancing the value of agro-industrial waste. Therefore, this study aimed to investigate the effect of different glycerol concentrations on the characteristics of edible films produced from kepok banana peels and agar. The parameters evaluated included moisture content, thickness, yield, and color. The experiment was conducted using a Completely Randomized Design (CRD) with three glycerol concentration treatments (0.5%, 1%, and 1.5%), each performed in triplicate. The results showed that glycerol addition significantly affected the moisture content, yield, and color of the Edible films, but had no significant effect on thickness. A glycerol concentration of 1% produced the best results, characterized by optimal moisture content and flexibility, high yield, and brighter color. This study demonstrates that the utilization of kepok banana peel waste in Edible film production has strong potential as an environmentally friendly alternative to conventional plastic packaging
