Rice is the staple food of most Indonesian people, making its availability a national priority. This study aims to analyze the effect of harvested area on national rice production using a time series linear regression approach based on monthly data in 2025. The research employed quantitative methods using secondary data analyzed with SPSS 27. The regression results produced the equation Ŷ = –0.067 + 0.003X. The t-test showed a significance value < 0.001, indicating that harvested area has a positive and significant effect on rice production. The coefficient of determination (R²) was 0.994, meaning 99.4% of rice production variation is explained by harvested area. These findings indicate that fluctuations in national rice production are largely determined by changes in harvested area rather than short-term productivity variations. Therefore, policies to increase rice production should prioritize maintaining harvested area through land protection, planting acceleration, and crop failure mitigation. The study contributes to providing an empirical model for short-term prediction of rice production in Indonesia.

This community service program was conducted in Manarap Baru Village, Banjar Regency, South Kalimantan, focusing on the utilization of rice husks as a planting medium to promote creative economic development.

Organic agriculture plays a vital role in Indonesia’s agricultural development, with a key challenge being how to boost productivity efficiently and sustainably. Liquid Organic Fertilizer (LOF) derived from natural materials provides an eco-friendly option to improve soil fertility and crop yields. Bamboo shoots (Bambusa spp.), rich in organic carbon and gibberellin, present strong potential as LOF raw material to support plant growth. This study evaluated the effect of bamboo shoot-based LOF on the growth and yield of white radish (Raphanus sativus). The research was conducted from May to August 2025 in Kalolok, Batupapan Village, Tana Toraja Regency, South Sulawesi, at an altitude of 775 m. LOF was produced by fermenting 200 kg of ground bamboo shoots with 4 kg palm sugar, 1 liter EM4, and 200 liters water for 14 days. Treatments consisted of 0, 100, 200, and 300 ml per liter of water, applied twice at two-week intervals starting 14 days after planting. Using a randomized block design with four treatments and three replications, variables observed included plant height, leaf number, tuber size, and yield. Results showed that 300 ml/liter LOF gave the best outcomes: tallest plants (27 cm), most leaves (15.89), largest tubers (29.37 cm length; 6.06 cm diameter), and highest weight (731 g/plant; 6936.67 g/plot). These effects are linked to balanced nutrients (N, P, K, Mg, Ca) enhancing vegetative growth and tuber development. Thus, bamboo shoot-based LOF at 300 ml/liter is recommended as an effective organic fertilizer for white radish.
