Lombok merupakan salah satu tujuan wisata utama yang ada di Indonesia, keindahan alamnya tidak kalah dengan Bali yang sudah terlebih dahulu terkenal di Manca Negara. Keberagaman budaya dan produk lokal yang dimiliki juga sangat banyak dan mendukung peningkatan jumlah kunjungan wisata. Promosi yang dilakukan oleh pemerintah tidak dapat mengakomodir semua obyek wisata dan mempromosikan produk lokal dari masyarakat tersebut, karena seiring dengan kesadaran masyarakat tentang pentingnya pariwisata dalam meningkatkan kesejahteraan, banyak sekali muncul obyek wisata baru dan produk- produk baru yang tidak tersentuh oleh promosi pemerintah. Dan promosi yang dilakukan secara konvensional membutuhkan biaya yang sangat mahal. Diera digital saat ini media sosial, memegang peranan sangat penting dalam mempromosikan sesuatu. Selain kemampuannya untuk mempromosikan produk ataupun obyek, media sosial juga bisa digunakan untuk membuat personal branding yang pada hilirnya dapat mendatangkan keuntungan materi. Untuk membuat konten yang menarik perlu pelatihan ketrampilan kepada masyarakat untuk dapat meningkatkan kemampuannya dalam membuat konten yang ditampilkan dalam media sosial sehingga lebih banyak orang melihat dan berkomentar yang pada akhirnya dapat menjadi media promosi yang murah

Kawasan Ekonomi Khusus (KEK) Mandalika merupakan salah satu destinasi pariwisata prioritas yang mulai dikenal dunia karena penyelenggaraan MotoGP dan kegiatan balapan lainnya yang berstandar nasional maupun internasional. Dalam mendukung kegiatan tersebut, aktivitas jual beli berkembang pesat, terutama oleh Pedagang Kaki Lima (PKL). Namun, dalam praktiknya, beberapa PKL menjajakan dagangan mereka dengan cara memaksa dan kurang sopan, yang dapat mengganggu kenyamanan wisatawan serta menurunkan citra pariwisata KEK Mandalika. Untuk mengatasi masalah ini, dikembangkan model bisnis digital yang didukung oleh teknologi dari Dinas Perdagangan NTB, yaitu NTB Mall. Program pengabdian ini melibatkan beberapa tahapan: persiapan aplikasi NTB Mall, pelatihan literasi digital, pelatihan model bisnis digital, serta pelatihan pengelolaan pasar modern. Hasil pengabdian menunjukkan bahwa Kelompok Sadar Wisata (Pokdarwis) siap menjadi agent of change, terbukti dengan hasil pengujian System Usability Scale (SUS) sebesar 85, yang menunjukkan tingkat penerimaan aplikasi yang tinggi. Dampak lain yang terukur dari program ini mencakup peningkatan keterampilan digital bagi PKL, pemahaman strategi pemasaran digital, serta pertumbuhan ekonomi bagi para pedagang yang telah berpartisipasi. Selain itu, program ini juga berkontribusi dalam meningkatkan tata kelola kawasan KEK Mandalika dengan menata lokasi berdagang yang lebih rapi dan terorganisir, sehingga menciptakan lingkungan wisata yang lebih nyaman.

Traditional Sasak weaving in Lombok faces major challenges such as counterfeit products, lack of supply chain transparency, and price disparities, all of which undermine sustainability and consumer trust. Blockchain technology offers potential solutions by improving transparency, security, and data integrity. However, adoption among weaving MSMEs (Micro, Small, and Medium Enterprises) remains limited due to low digital literacy and limited awareness of blockchain’s benefits. This study evaluates the acceptance of blockchain technology among traditional weaving MSMEs in Lombok using an Extended Technology Acceptance Model (TAM). Beyond the standard constructs Perceived Usefulness (PU) and Perceived Ease of Use (PEU) the model integrates Perceived Trust (PT), Perceived Privacy (PP), Perceived Security (PS), Social Influence (SI), and Customer Satisfaction (CS). A quantitative survey was conducted with 50 MSME actors in Sukarara, Lombok. Findings show that PEU significantly influences PU (path coefficient = 0.798; t = 11.520; p < 0.001), while Attitude Toward Using (ATU) strongly affects Behavioral Intention to Use (BITU) (path coefficient = 0.775; t = 5.147; p < 0.001). Both PS and PP significantly impact PT, with path coefficients of 0.410 and 0.380, respectively. Conversely, SI and CS have no significant effect on BITU. The model demonstrates strong explanatory power, with R² values of 81.7% for ATU and 80.7% for BITU. These results highlight that technical factors particularly usability and trust are more influential than social factors in determining blockchain adoption. The study recommends simplifying technology, improving digital literacy, and ensuring policy support to drive wider adoption among traditional MSMEs.

Based on WHO data from 2024, Indonesia ranks second after India as the country with the highest number of tuberculosis (TB) cases in the world. Low patient adherence to regular medication intake, caused by the weakness of manual monitoring systems by healthcare workers, remains a major challenge in TB control. This study aims to develop a mobile application to monitor tuberculosis treatment and improve patient medication adherence. The application was developed using a software engineering approach with the Personal Extreme Programming (PXP) method, involving stages of planning, design, implementation, and iterative testing. Data collection techniques included observation, structured interviews, and User Acceptance Testing (UAT) through an online Likert-scale-based questionnaire. The outcome of this study is a mobile-based application featuring medication reminders, daily consumption reporting, monitoring by healthcare workers, and the provision of educational information. Black-box testing results indicated that all application features functioned as intended, while UAT results showed that the application is user-friendly and supports healthcare workers in effectively monitoring patient treatment. These findings demonstrate that the application can serve as a digital solution to improve TB treatment adherence and strengthen medication monitoring systems, particularly in high-burden areas.
