Pengaruh Limbah Cangkang Telur Ayam dan Limbah CPO terhadap Pertumbuhan Serta Produksi Tanaman Seledri(Apium Graveolens l)
The research entitled "The Effect of Chicken Eggshells and CPO Waste on the Growth and Production of Celery Plants (Apium graveolens L.)" was carried out at the Experimental Garden of the Faculty of Agriculture, Islamic University of Riau, Jalan Kaharuddin Nasution Km 11 No.113. Air Cold Village, Bukit Raya District, Pekanbaru City. The research was conducted for 4 months from November 2022 to February 2023. This study aimed to determine the main effect of chicken egg shell waste and CPO waste on the growth and production of celery plants. The design used in this study was a completely randomized factorial design, consisting of 2 factors. The first factor was the dose of chicken eggshell waste consisting of 4 levels, namely 0, 7.5, 15 and 22.5 g/polybag. The second factor was the dose of CPO waste consisting of 4 levels, namely 0, 100, 200, 300. The parameters observed were plant height, net assimilation rate, relative growth rate, number of stems, number of tillers, fresh weight of plants and root volume. Observational data were analyzed statistically and carried out with the Honest Significant Difference Follow-up Test (BNJ) at the 5% level. The results showed that the interaction of giving Chicken Eggshells and CPO Waste had a significant effect on all parameters with the best combination of Chicken Eggshell concentrations having a significant effect on all observation parameters. The best treatment for chicken egg shells is 22.5 g/polybag. The main effect of real CPO waste dosage on all observation parameters. The best treatment is the dose of CPO Waste 300 ml/polybag.
