Abstract

High blood sugar levels in DM can inhibit wound healing and increase the risk of infection. Diabetic ulcer therapy with commercial anti-inflammatory drugs is relatively expensive and has side effects. VCO and diamond leaf extract have the potential as an alternative therapy with anti-inflammatory effects, but further research is needed regarding the right dose. This study aimed to analyze the impact of VCO administration with supplementation of diamond leaf extract (Azadirachta indica L.) on IL-6 levels in wound healing of type 2 DM model rats. This research is a true experimental research with a post-test-only control group design. This study used 25 male mice which were divided into five groups, namely: group P1 5% Intaran leaf extract, P2 10% Intaran leaf extract, P3 15% Intaran leaf extract, negative control (NaCl 0.9%), and positive control (Povidone Iodine). Data were analyzed using the Shapiro-Wilk statistical test, followed by the One-Way Anova test, the confirmation test, and the LSD test. The results showed a significant difference in IL-6 levels between the treatment groups, as evidenced by the One Way ANOVA statistical test results. Considerable value was obtained in the test of IL-6 levels on day 4 Sig. 0.003 and day 14 Sig. 0,046. It can be concluded that the treatment group giving VCO supplementation with intern leaf extract at a concentration of 10% affects wound healing with a decrease in IL-6 levels on day 14. This study provides an important contribution to DM wound healing efforts by using affordable natural ingredients with low potential side effects.

Abstract

More technological innovation in the tourism sector must be integrated with educational aspects and digital literacy, especially during a pandemic that limits physical visits to tourist attractions. Although several tourism applications have been developed, only a few have been specifically designed to improve digital literacy and visitor knowledge in terms of educational content and integration with the school curriculum. This research aims to create a virtual tour-based edu-tourism application that is packaged with virtual reality applications. This research is a research and development using the ADDIE model. The subjects of this research were randomly 250 teachers and high school / vocational school students. The data collection method was a questionnaire using an instrument in the form of an instrument sheet. After the data was collected, it was analyzed using quantitative and qualitative descriptive data analysis methods. The results showed that the design of the virtual tour technology application received a very good assessment in the aspects of media, material, discussion, and display. This is also in line with the teacher's response, which assessed these aspects positively, with the highest score given to the media aspect, followed by the material, discussion, and display. This study concludes that the virtual tour-based eduwisata application packaged with virtual reality applications is effective in improving the literacy skills of teachers and students regarding eduwisata. The results of this study indicate that virtual tour applications can be implemented as interactive learning media that can improve student and teacher literacy in the field of edu-tourism.

Abstract

Upaya mencapai efisiensi energi, perlu pengurangan penggunaan AC yang tidak efisien, mengakibatkan konsumsi energi tinggi dan emisi karbon. Beban termal adalah total panas yang harus dikeluarkan dari ruangan untuk mempertahankan suhu nyaman, termasuk beban kalor sensibel dan laten. Tujuan penelitian ini untuk menganalisis manajemen pengondisian suhu ruangan berdasarkan beban termal menggunakan sensor thermopile infrared array. Jenis penelitian merupakan studi literatur. Sistem otomatisasi berbasis kamera termal AMG8833 dengan resolusi 8x8 piksel dikembangkan untuk mendeteksi kondisi ruangan secara efisien. ESP32 digunakan sebagai mikrokontroler untuk mengolah data dari kamera termal dan mengubah set point suhu ruangan menggunakan IR Transmitter. Pengaturan suhu dilakukan dengan mengatur fan AC berdasarkan hukum konveksi, sehingga distribusi udara lebih efektif. Sistem ini dilengkapi antarmuka dan LCD untuk pemantauan real-time serta pengubahan suhu langsung. Pengujian menunjukkan bahwa sistem berhasil mengoptimalkan suhu dan kenyamanan termal dengan penghematan daya 0.365 kWh. Sistem ini tidak hanya mengurangi konsumsi daya dan emisi karbon, tetapi juga meningkatkan kenyamanan dan produktivitas penghuni ruangan.

Abstract

Digitalisasi wisata telah menjadi tren global yang memerlukan pendekatan sistem cerdas dalam pengelolaan dan pemasaran destinasi wisata. Pengembangan metode klasterisasi yang efektif dapat menjadi langkah kunci untuk mengidentifikasi, mengelompokkan, dan memahami potensi wisata yang beragam di Indonesia. Dengan adanya pengembangan metode klasterisasi yang canggih maka dapat memungkinkan terwujudnya strategi digital yang lebih efektif. Pengembangan Metode Klasterisasi yang efektif penting untuk mengidentifikasi dan memahami beragam potensi pariwisata di Indonesia. Hal ini menjadi urgensi masalah yang sangat penting mengingat banyak wisatawan yang kesulitan memilih tempat wisata terbaik. Tujuan Penelitian ini untuk mengembangkan metode klasterisasi untuk mendukung digitalisasi pariwisata di Indonesia, dengan mengintegrasikan Algoritma K-Means Clustering dan Weighted Product. Pendekatan yang digunakan dalam penelitian ini yakni dengan Metode untuk mengelompokkan potensi wisata dalam tiga klaster yaitu besar, sedang, dan kecil. Kemudian dilanjutkan rekomendasi wisata terbaik berdasarkan kriteria: keindahan, budaya, akses, fasilitas, aktivitas, iklim, keunikan, keamanan, keterlibatan, kebersihan, promosi. Penelitian ini meliputi studi literatur, pengumpulan data, pengembangan metode klasterisasi dan pengujian sistem. Model ini diharapkan dapat membantu pengelola pariwisata dalam mewujudkan digitalisasi yang lebih efektif di Indonesia. Hasilnya akhir dari model klasterisasi ini adalah tiga klaster pariwisata dengan tingkat potensi yang berbeda-beda yaitu pada cluster 1 adalah 12%, cluster 2 adalah 54% dan cluster 3 adalah 34%. Pengujian yang dilakukan pada uji fungsionalitas menunjukan hasil diterima pada seluruh skenario uji dan hasil uji Silhouette Coefisien menunjukkan struktur data yang kuat dengan skor rata-rata 0,87.
