Abstract

Eggshell-based liquid organic fertilizer (LOF) is a sustainable nutrient source rich in nitrogen (N), phosphorus (P), and potassium (K), essential for plant growth. This study investigated the effects of eggshell LOF on the growth of leek plants (Allium fistulosum L.) using a Completely Randomized Design (CRD) with five concentration treatments: 0% (P0, control), 5% (P1), 10% (P2), 15% (P3), and 20% (P4), each replicated three times. The experiment was conducted in Kel. Isola, Kec. Sukasari, Bandung City, Indonesia, during December 2022. Plant height was measured every three days for two weeks as the primary growth parameter. Results demonstrated significant differences (*p* 0.05) among treatments, with the 20% LOF concentration (P4) yielding the highest average plant height (22.7 cm). In contrast, the 5% LOF group (P1) showed no growth, indicating plant mortality. A positive correlation was observed between LOF concentration and plant height, confirming that higher nutrient availability directly enhances leek growth. These findings highlight the efficacy of eggshell LOF, particularly at 20% concentration, as a viable organic fertilizer for improving Allium fistulosum productivity. Further research is recommended to explore optimal concentrations beyond 20% and assess long-term soil health impacts.

Abstract

Macrozoobenthos are aquatic organisms that live on the bottom of the water. Currently, the upstream Cikapundung River is indicated to be polluted by garbage, household waste, industrial waste, agricultural waste and livestock manure. This study aims to determine the diversity of macrozoobenthos as a bioindicator of water quality in the upstream Cikapundung river based on physical, chemical and biological parameters. This research was conducted in April 2023. The research used the exploration method. Macrozoobenthos sampling consists of five locations namely; Curug Omas, Curug Lalay, Kidang, Curug Koleang and Curug Dago. The results of the data analysis of the calculation of the Diversity Index, Abundance and Dominance indicate that the upstream Cikapundung river is classified as moderately polluted. This is evidenced by the diversity value obtained, which falls within the range of 1.94 - 2 (2.0). The high abundance index value is observed in location 2, while the dominance index value is 0.50 D ≤ 0.75. A total of nine species were identified in the benthic samples, which were classified into four classes, nine families, and seven genera. The dominating benthos of the five locations is Planaria sp. Based on an analysis of biotic and abiotic components, the upstream Cikapundung river is classified as exhibiting minimal pollution.
