Abstract

Farmers in specific region can play a crucial role in preventing the extinction of rare rice varieties by maintaining their commitment to local rice production. This not only contributes to the economic stability of the community but also necessitates exploration efforts to identify and gather specific plant species at risk of extinction. This study employs a descriptive research design to identify, gather, and compare the relationships between local rice genotypes in the Kuantan Singingi regency. The survey method utilizes a planned sample of rice seeds.The exploration process involves observing geographic coordinate locations, collecting local rice seeds, and examining grain and rice morphology based on Bioversity International, IRRI, and WARDA standards from 2007. The Kuantan River, with an altitude ranging from 28.95 to 61.56 meters above sea level, is prone to frequent flooding. A morphological study of grains reveals that, out of 26 local rice genotypes, one pair exhibits the highest similarity rate of 71% when compared to more diverse types. Notably, the white sironda rice from Pulau Madina village in Kuantan Hilir district and pandan wangi rice from Pauh Angit village in Pangean district are identified as the most identical genotypes. By identifying and preserving unique and highly-potential indigenous rice genotypes, this research significantly contributes to the enhancement of food stability, rural economy, and genetic resilience of rice plasma in Indonesia.

Abstract

Indonesia's high rice consumption, with a population of 284.4 million, stands in contrast to the national production levels in 2024. Based on data from that year, total annual rice production reached only approximately 29.80 million tons, which was insufficient to meet domestic demand. This shortfall occurred as paddy production in 2024 declined to 53.14 million tons (dry harvested grain), a 2.43% decrease compared to the 53.98 million tons produced in 2023. The environmentally friendly System of Rice Intensification (SRI) can enhance productivity by up to 50%. Indonesia's rich marine biodiversity, particularly seaweed, can serve as a biostimulant through extraction. Biostimulants contain compounds and microorganisms that enhance nutrient use efficiency in plants. This study aimed to evaluate the effects of seaweed extract concentrations on the growth and yield of rice and to assess its potential as a natural biostimulant for sustainable rice productivity, supporting organic farming. The study was conducted from June to October 2025 in rice fields at Koto Luar, Pauh, Padang. A Randomized Block Design (RBD) with one factor seaweed extract concentrations at 0%, 0.4%, 0.8%, 1.2%, and 1.6%. The data was analysed with analysis of variance at a 5% significance level and mean comparison of the Duncan’s New Multiple Range Test (DMRT) via STAR® (Statistical Tool for Agricultural Research). The research results showed that the seaweed extract at the 1.6% concentration was the best treatment effected of plant growth, yield components and crop yield of rice. The findings recommend increasing seaweed extract concentrations to enhance rice growth and yield.
