Factors Influencing Biofortified Inpari IR Nutri Zinc Rice Production in Margatiga, East Lampung, Indonesia

Sri Indaryati — 2026-07-07

Purpose: This study examines the production factors that determine the output of Inpari IR Nutri Zinc, a zinc-biofortified rice variety cultivated by smallholder farmers in Jayaguna and Negeri Tua villages, Margatiga Subdistrict, East Lampung Regency, Indonesia, and evaluates the extent to which these factors jointly explain variation in farm-level rice output.
Methodology: A quantitative explanatory survey design was applied to fifteen farmers selected through simple random sampling from a population of 104 registered Inpari Nutri Zinc growers. Primary data on land area, seed quantity, urea and NPK Phonska fertilizer use, herbicide, fungicide, rodenticide, and insecticide application, and labor input were collected through structured interviews and analyzed using multiple linear regression in SPSS.
Results: The regression model produced a coefficient of determination of 0.949 and an F-statistic of 90.012 at a significance level below 0.05, indicating that the nine production factors jointly explain 94.9% of the variance in rice output, with land area and urea fertilizer emerging as the most influential partial predictors.
Conclusions: Land expansion and balanced fertilization remain the principal levers for raising Inpari Nutri Zinc productivity in the study area.
Limitations: The small sample size and single-season crosssectional design constrain the generalizability of the coefficients. Contributions: The study offers empirically grounded guidance for extension planning and input allocation policy supporting biofortified rice diffusion in stunting-prone regions of Lampung Province.

Analyzing Greenwashing Impact on Financial Performance and Profitability of Publicly Listed Manufacturing Companies in Makassar

Istianah Hadaming — 2026-07-15

Purpose: This study empirically tests the effect of greenwashing practices on the financial performance of publicly listed manufacturing companies operating in Makassar between 2021 and 2025, using Return on Assets as the profitability proxy.
Methodology: A quantitative approach was applied using secondary data drawn from annual reports and sustainability reports. Simple linear regression together with a content analysis method was used to score the level of greenwashing for each company-year observation.
Results: The relationship between greenwashing and Return on Assets was negative but not statistically significant, with a regression coefficient of negative 0.008 and a significance value of 0.911, while the model explained only 0.1% of the variance in profitability.
Conclusions: The negative direction confirms that symbolic environmental claims made without matching action tend to create operational inefficiency that weighs on profit, although the regional capital market remains pragmatic and continues to value traditional financial metrics above sustainability narratives.
Limitations: The study is confined to a small sample of manufacturers with operations in the Makassar industrial area and relies solely on Return on Assets as the financial performance proxy.
Contribution: The study offers empirical evidence on greenwashing dynamics at the regional operational level, highlighting the gap between centralized corporate narratives and local realization, and points toward the need for stronger regional sustainability verification mechanisms.
