<![CDATA[Mangkraknya Mall UFO sejak 2015 menurunkan vitalitas ekonomi pusat Kota Kediri, sementara itu pelaku UMKM membutuhkan wadah komersial yang adaptif dan terjangkau. Penelitian ini bertujuan meredesain bangunan tersebut menjadi Pusat UMKM melalui penerapan prinsip 3L (Long Life, Loose Fit, Low Energy) dan pendekatan Sustainable Architecture. Menggunakan metode pragmatis berbasis evaluasi tata massa dan ruang luar, hasil perancangan mengintegrasikan aspek Long Life diterapkan melalui Wood Plastic Composite dan roster beton. Aspek Loose Fit diterapkan melalui konfigurasi kios modular yang fleksibel tanpa mengubah struktur utama, sedangkan Low Energy diterapkan melalui strategi desain pasif seperti sirkulasi silang, pencahayaan alami, dan peneduh fasad. Kata Kunci: Prinsip 3L, Redesain Mal, Pusat UMKM, Wadah Komunitas, Sustainable Architecture The abandonment of UFO Mall since 2015 has degraded the economic vitality of central Kediri City, while MSME actors require adaptive and affordable commercial spaces. This research aims to redesign the building into an MSME Center through the application of the 3L principles (Long Life, Loose Fit, Low Energy) and a Sustainable Architecture approach. Utilizing a pragmatic method based on spatial massing and outdoor space evaluation, the design results integrate the Long Life aspect applied through Wood Plastic Composite and concrete roster. The Loose Fit aspect is applied through a flexible modular booth configuration without altering the main structure, while Low Energy is applied through passive design strategies such as cross ventilation, natural lighting, and facade shading.
