Abstract

This research aims to synergize local microorganisms (LMO) of golden snails (Pomacea canaliculata) and seed age in optimizing rice seed germination (Oryza sativa L.). Golden snail LMO, which is rich in organic nutrients and beneficial microorganisms, has the potential to improve seed quality and viability. The study used a factorial randomized block design (RBD) with two factors: golden snail LMO concentration (Control, 20 ml/L water, 40 ml/L water) and seedling age (7 days, 11 days, and 15 days after sowing). The variables observed included seed germination, simultaneity grows and growth speed. The results showed that the golden snail LMO concentration of 20 ml/L and seed age of 11 days after sowing gave the highest results for the observed variables, namely seed germination and growth speed while the interaction between golden snail LMO concentration mas 40 ml/L and seed age of 15 days after sowing gave the highest results for the variable observing growth synchrony. The combination of the two factors showed a positive interaction that supported the germination process effectively. This study concludes that the use of golden snail LMO and selecting the right seed age can be an ecological and efficient approach to increasing rice seed productivity, supporting sustainable agriculture.

Abstract

The knowledge of farming methods and various traditional agricultural tools owned by the ancestors of the people of East Kalimantan has been passed down to their descendants, remaining simple and used by a group of people from generation to generation, forming part of their technological system, according to their cultural conceptions. However, the current agricultural transformation in Samarinda shows a clear shift from traditional to modern farming systems, evident in the application of modern technology in agricultural activities. This study examines the transformation process, its driving factors, socio-economic impacts, and challenges and development strategies. Data were collected through literature review and interviews with local farmers. The results indicate that modern agriculture increases productivity and work efficiency, attracts younger generations, and supports food security in the region. However, limited land and access to technology are key challenges. The study concludes that agricultural modernization in Samarinda must be supported by inclusive policies that integrate technology, strengthen farmer institutions, and empower young people.
