Abstract

Sustainable agriculture plays a crucial role in improving food security by efficiently and environmentally friendly means of meeting food needs. In Indonesia, rice is a vital staple food source and source of livelihood for the majority of rural residents. However, conventional agricultural practices, which rely heavily on chemical fertilizers, synthetic pesticides, and excessive land exploitation, have led to various environmental and social problems. Consequently, farmers' understanding and perceptions of the concept of sustainable agriculture remain largely unknown. This study aims to determine rice farmers' perceptions of sustainable agriculture through the application of Good Agricultural Practice (GAP) and to identify factors influencing their perceptions. The study was conducted in Rukam Village, Mendo Barat District, from September to November 2025. A survey method was used, with 30 rice farmers as respondents, using purposive sampling. Data were analyzed descriptively to determine farmers' perceptions, and quantitatively using multiple linear regression to analyze factors influencing farmers' perceptions. The analysis showed that farmers' perceptions of GAP implementation in lowland rice were categorized as very good, with a percentage of 81.88%, covering economic, social, and technical aspects. The results of multiple linear regression are Y = 12.814746 – 0.331873 X1 – 0.407773 X2 + 0.527081 X3 + 0.340421 X4. The variables of education and extension workers have a significant effect on farmers' perceptions in the implementation of GAP for rice commodities, while the variables of farming experience and cultivation techniques do not have a significant effect on farmers' perceptions in the implementation of GAP for rice commodities.

Abstract

Genotypic performance in rice is significantly influenced by environmental heterogeneity, necessitating multi-location evaluation to identify adaptive and stable upland rice lines. This study evaluates the uniformity, adaptability, stability, and yield potential of five breeding lines (G1–G5) and five released varieties across two contrasting island environments: Jambi (Sumatra) and Mataram (Nusa Tenggara), from June to December 2024. A randomized block design is employed, and data are analyzed using ANOVA, DMRT, correlation analysis, phenotypic and genotypic coefficient of variation, and broad-sense heritability. Significant differences are detected among genotypes for all traits except filled-grain weight, with G2 exhibiting the highest yield per plot. All traits are significantly affected by location, indicating a strong environmental influence, while genotype and environment contributed independently to trait expression. Correlation patterns are generally consistent across locations, with the strongest association observed between yield per plot and grain weight. The majority of traits exhibit broad phenotypic and genotypic variability (87.5%), and 66.7% of the evaluated traits show high heritability, suggesting substantial potential for genetic improvement. Based on performance, lines G2 (white rice) and G5 (red rice) are recommended for further development and cultivation in upland rice ecosystems in Indonesia.

Abstract

The production of shallot varieties is influenced by the adequacy of nutrients and soil conditions. Soil that has low nutrient content requires high nutrient input. Ultisol soil is one of the marginal soils, this soil requires additional nutrients from the right type of manure to increase crop yields. The study aims to determine the type of manure that can increase the yield of Lokananta shallots on ultisol soil. The research location is in Pangkalpinang City, Bangka Belitung Islands Province. The research period is from October 2024 to April 2025. The eksperiment used a Randomized Block Design, consisting of 4 groups based on the size of the bulbs used as seeds. The treatments were 5 types of manure (chicken, cow, goat, swallow, and bat) and control (without additional fertilizer). The parameters observed were plant height, number of leaves, number of shoots, stem diameter, bulb diameter, wet weight of bulbs, dry weight of bulbs, and yield per plot. The harvested bulbs were analyzed for water content, reducing sugar, and essential oils (VOC). The results of the study showed that the best type of manure is that derived from chicken manure. Chicken manure has been proven to be able to increase the number of leaves, number of shoots, and number of plant bulbs, tends to be higher in yield of bulbs per plant. Red onion bulbs have the highest reducing sugar content in the chicken manure treatment, while the lowest water content is found in bat manure.
