Abstract

Sepak bola mini (mini soccer) adalah cabang olahraga sepak bola yang dimainkan di lapangan berukuran lebih kecil dengan jumlah pemain lebih sedikit, sehingga menjadi pilihan populer terutama di perkotaan dengan keterbatasan lapangan besar. Namun, pengelola sering menghadapi kesulitan dalam meratakan waktu penyewaan, karena jam tertentu cenderung menjadi favorit, sementara jam lainnya kurang diminati. Penelitian ini bertujuan untuk menganalisis pola penyewaan lapangan mini soccer berdasarkan waktu penyewaan guna mendukung manajemen dalam menentukan strategi bisnis yang efektif. Penelitian ini menggunakan metode klastering dengan algoritma K-Means. Analisis dilakukan untuk mengelompokkan data penyewaan berdasarkan parameter seperti waktu mulai, durasi, dan frekuensi transaksi. Hasilnya menunjukkan data penyewaan dapat dikelompokkan ke dalam beberapa cluster, yaitu cluster tinggi dan rendah yang mencerminkan segmentasi pola penyewaan lapangan. Setiap cluster memberikan wawasan tentang perilaku penyewa, seperti waktu penyewaan paling populer, durasi rata-rata, dan preferensi hari tertentu. Informasi ini membantu manajemen merancang strategi terarah, seperti promosi atau bundling paket. Penelitian membuktikan algoritma K-Means efektif dalam memahami pola penyewaan dan mendukung pengambilan keputusan berbasis data. Implikasi hasil ini dapat meningkatkan pengelolaan operasional serta loyalitas pelanggan melalui strategi bisnis yang lebih relevan dan kompetitif.

Abstract

Digitalisasi layanan kesehatan mendorong BPJS Kesehatan mengembangkan platform seperti Mobile JKN sebagai layanan kesehatan digital. Meskipun aplikasi ini telah diluncurkan secara luas, Minimnya pemanfaatan aplikasi secara berulang menunjukkan tantangan dalam mempertahankan pengguna aktif. Oleh karena itu, penting untuk mengevaluasi pengalaman pengguna guna memastikan aplikasi tidak hanya diunduh, tetapi juga digunakan secara berkelanjutan. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi retensi pengguna terhadap aplikasi Mobile JKN dengan pendekatan HEART Metrics, yang mencakup lima dimensi utama: Happiness, Engagement, Adoption, Retention, dan Task Success. Data dikumpulkan melalui penyebaran kuesioner kepada 107 pengguna aktif, kemudian dianalisis menggunakan regresi linier berganda. Hasil analisis menunjukkan bahwa dimensi Engagement dan Task Success memiliki pengaruh signifikan terhadap retensi pengguna, sementara dimensi lainnya tidak menunjukkan pengaruh yang signifikan secara statistik. Temuan ini mengindikasikan bahwa keterlibatan pengguna dan kemudahan dalam menyelesaikan tugas menjadi faktor penting dalam mempertahankan penggunaan aplikasi. Berdasarkan hasil tersebut, disarankan agar pengembangan aplikasi Mobile JKN difokuskan pada peningkatan interaktivitas serta penyederhanaan antarmuka guna meningkatkan kenyamanan dan loyalitas pengguna.

Abstract

Purpose: Twitter related to mental health has great potential as a medium to provide important information to the public and health organizations on a large scale, but an evaluation of tweet data related to mental health disorders has not been carried out. This study aims to classify tweet data to determine the most common mental health disorders in Indonesia based on the symptoms experienced.Methodology: The classification process is carried out using cosine similarity calculations between tweets data and keywords which are compiled based on theoretical studies and optimization of the LDA topic modeling results.Findings/result:The classification results show that the most discussed issues on Twitter are depression, bipolar, schizophrenia, dementia, and PTSD. Based on these results it can be interpreted that the level of prevalence and public attention to depressive diorders is quite high compared to other disorders. From the results of the classification, it is also possible to identify the most discussed symptoms throughthe emergence of keywords from each category.Originality: Classification is calculated based on the cosine similarity between tweets and keywords compiled from human judgement and enriched using the results of LDA topic modeling to improve classification performance

Abstract

Purpose: Social media, particularly Twitter, provides a venue for individuals to share their thoughts. The public's perception of mental illnesses is often debated on Twitter. So yet, no evaluation of community tweets connected to data on mental health conditions has been performed. The purpose of this study is to examine tweets linked to mental illnesses in Indonesia in order to identify the themes of conversation and the polarity trends of these tweets.Design/methodology/approach: To address this issue, the K-Means Clustering algorithm is utilized to aggregate tweet data that is used to find themes of conversation. The emotion polarity value of each cluster result was then determined using the Support Vector Machine (SVM) approach.Findings/results: This study generated five topic clusters based on tweets about mental illness. While sentiment analysis revealed that all clusters had more negative sentiment classes than positive. Cluster 4 and Cluster 5 had the highest number of negative sentiment values. These clusters emphasize the necessity of consulting with psychiatrists and psychologists if people have mental health disorders, as well as financing for mental health disorder treatment through BPJS Kesehatan services.Originality/value/state of the art: The analysis was done in two stages: data grouping to find themes of conversation using K-Means clustering and SVM to look for positive and negative polarity values associated to twitter data about mental illness.

Abstract

The advancement of digital technology has significantly driven innovation in health applications, offering users practical tools to monitor their physical and emotional well-being. Among these, Flo: Period & Pregnancy Tracker stands out as a popular application designed to help women track their reproductive cycles, ovulation, and associated hormonal symptoms. This study aims to evaluate the user experience of new users of the Flo application across two age groups: 12–25 years and 26–45 years, to understand their perceptions of comfort and ease of use, employing a quantitative approach with the User Experience Questionnaire (UEQ). Analysis results indicate that both age groups generally provided positive assessments of the application. The Stimulation and Efficiency aspects received the highest scores, while Novelty was the lowest-scoring aspect. Further analysis revealed that the 12– 25 year age group tended to prioritize hedonic qualities (such as Stimulation and Attractiveness), whereas the 26– 45 year age group valued pragmatic qualities (such as Efficiency and Perspicuity) more in their initial app usage experience. These findings underscore the importance of UI/UX design that adapts to the differing needs and expectations of users across age segments for overall experience improvement. It is important to note that the imbalance in the number of respondents between age groups is a limitation of this study, which may affect the validity of peer-to-peer comparisons and the generalizability of results due to constraints in time and primary respondent data availability.
