This study aims to understand how the Online Single Submission (OSS) system is implemented at the Investment and One-Stop Integrated Services Office (DPMPTSP) of Jambi Province, and how it influences service accessibility, investment growth, and local economic development. OSS is a digital licensing system developed by the Indonesian government to simplify and accelerate the business licensing process through an integrated platform. This research uses a descriptive qualitative method, with data collected through interviews, observations, and documentation from DPMPTSP staff and business owners who use the OSS system. The results show that OSS helps simplify the licensing process and makes services more transparent. However, there are still challenges such as limited user understanding, uneven internet access, and weak inter-agency coordination. Despite these challenges, OSS is considered to have supported a more favorable investment climate and encouraged regional economic growth. Therefore, it is necessary to improve users' digital literacy, update the OSS system, and strengthen cooperation among related institutions.

Jambi batik has certain characteristics, its motifs or designs are related to the richness of culture and nature by reflecting Jambi's social/culture, depicting Jambi's resources and having historical value. One of them is in Merangin Regency, especially in Muara Jernih Village, Tabir Ulu District. The UP2K PKK Team of Muara Jernih Village took steps to explore local wisdom by producing batik. The batik they produce has its own regional uniqueness with the Kepayang Mabuk batik motif, Lukah Enjab Tigo batik and the Tugu Perjuangan Perang Bukit Palumun batik. This batik has begun to be widely liked and worn by residents, this will certainly be a high economic value for the PKK mothers of Muara Jernih Village who dare to take creative steps to explore the potential of the region into a productive business. However, in its development there are several problems that become obstacles in producing and introducing the existence of the batik. The identified problems concern capital, production management, labor and batik marketing. This is where the importance of increasing productivity lies. Productivity is the main goal in industrial activities. Productivity reflects public awareness of the impact of productivity on economic growth, living standards, and competitiveness.
