Abstract

Rambutan (Nephelium lappaceum L.) is a fruit that is suitable for growing in the tropics area. However, information on physiological responses and secondary metabolite profiles on artificial light treatment has not been reported. This study aims to study the response of rambutan plants to the application of artificial light from LED (Light Emitting Diode). The study was conducted in the screenhouse nursery using a two-factor nested plot design, namely LED as light source and cultivar. The LED light sources used red, blue, and white with application duration for 21 hours while the cultivars used Sikoneng, Parakan, Cilebak, Gravel, and Garuda cultivars. The results showed that rambutan plants that were given additional blue LEDs contained higher chlorophyll and leaf as glucose and fructose compared to another treatments. The results of the secondary metabolite profiles showed the largest Neophytadiene compound found in the Parakan cultivar under LED red treatment. Meanwhile, the compound that has the greatest abundance in white LEDs is 1-Propene, 3-[(4-nitrobutyl)thio]. Keywords: chlorophyll, photosynthesis, glucose, light spectrum, secondary metabolite

Abstract

This study analyzes the effect of Material Flow Cost Accounting (MFCA) on the circular economy with sustainable finance strategy as a mediating variable in personal care companies listed on the Indonesia, Malaysia, and Thailand stock exchanges for the 2020-2024 period, amidst the challenges of plastic waste in the ASEAN cosmetics sector. The objective is to test the causal relationship and mediation role using a quantitative panel data regression approach. The population includes non-cyclical consumer companies, a purposive sample of 70 observations from annual reports. Instruments include the CE Index (10 indicators), MFCA ratio, and SDGs Index (17 indicators) via content analysis; the analysis includes the Chow-Hausman test, regression, and Sobel test. The results show that MFCA has a significant negative effect on the circular economy (β=-0.409, p=0.042), sustainable finance strategy has a positive effect (β=1.128, p<0.001), but does not mediate (H2 is not significant). In conclusion, companies need to strategically integrate MFCA into green investments for an effective circular transition.
