Abstract

Exposure to environmental waste such as landfill leachate has the potential to cause genotoxic effects and oxidative stress impacting the mammalian reproductive system. This study examined the effects of Sarimukti Landfill Leachate (LTS) on sperm DNA damage and testicular oxidative stress in male Wistar rats. Rats were exposed to LTS at concentrations of 0%, 35%, and 63% during distinct spermatogenesis stages: mitosis (MTS), meiosis (MSS), and spermiogenesis (SMGS). Sperm DNA damage was assessed using the Sperm Chromatin Dispersion (SCD) assay, while testicular oxidative stress was measured by quantifying Malondialdehyde (MDA) and total protein levels. The results showed dose-dependent sperm DNA damage across all spermatogenesis stages, with the most significant damage observed at the 63% LTS dose. Sperm DNA damage levels were highest in the MTS group (93.53%), followed by MSS (87.5%) and SMGS (86.8%). The 63% LTS dose also increased testicular lipid peroxidation, as indicated by elevated MDA levels (4.63 µM/mL). This suggests that LTS can damage lipid components in testicular tissue. Additionally, the 63% LTS dose reduced total protein levels in testicular tissue to 63.55 µg/mL, compared to 108.31 µg/mL in the control group. Heavy metals (arsenic, plumbum, nickel, chromium) and organic pollutants in LTS generated reactive oxygen species (ROS) in germ cells, disrupting cellular repair mechanisms also inducing lipid and protein oxidation. This oxidative stress further exacerbated sperm chromatin fragmentation. These findings highlight the reproductive toxicity of landfill leachate and emphasize the need for protective measures during early spermatogenesis stages. This study provides insights into the environmental impacts on male fertility and underscores the risks of genotoxic exposure.

Abstract

Pinus merkusii Jung. Devr. is a multipurpose tree species that is widely cultivated for timber, resin production, and land conservation. Nearly all parts of the tree are utilized, making it highly valuable. However, the high demand for its products is not met by its low natural regenerative capacity, which poses challenges for sustainable management. To address this, somatic embryogenesis, an in vitro propagation technique, has been explored as an alternative method for multiplying conifer species like Pinus merkusii. This study aims to assess the in vitro response of megagametophyte explants cultured on DCR medium with various combinations of 2,4-D and kinetin. The concentrations of 2,4-D tested were 0 µM, 7 µM, 9 µM, and 11 µM, while kinetin was tested at 0 µM, 2 µM, 3 µM, and 4 µM. The explants used were megagametophytes from female strobili measuring 5-7 cm, containing young zygotic embryos in the preembryo stage. After two months of cultivation in the dark, the explants exhibited responses such as enlargement, callus formation, and germination. The highest response rates for explant enlargement, callus formation, and germination were observed in the combinations of DK00 and DK04 (33.33%), DK70 and DK114 (33.33%), and DK72 and DK114 (44.44%). No somatic embryo formation was observed, possibly due to the age of the explants.

Abstract

Banana peel consists of nitrogen atoms, sulfur and organic materials such as carboxylic acids that can function to bind pollutant molecules. The purpose of this research is to make King Banana (Musa acuminate) peel as filtration media to improve the physical quality of water including water clarity, pH value, TDS and Dissolved Oxygen (DO). There are three stages carried out, including preparation of banana peel waste, adjusting the media and filtration time and data analysis. The preparation process of banana peel waste is done by cleaning the banana peel then dried and mashed, then alkalized using 0.5 N NaOH. Then a variation in the amount of filtration media is made, namely: 60 g, 80 g and 100 g of plantain peels formulated using an additional 30 grams of zeolite with variations in filtration time, namely: 3 hours, 6 hours and 9 hours. The filtration results obtained using a variation of 100 grams of filtration media with a filtration time of 9 hours is the best media combination where the results obtained show an increase in water clarity, pH 5.41 and an increase in DO (Dissolve oxygen) of 20.

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.
