Abstract

Despite its ecological significance, including its function as a sink for pollutants, a provider of oxygen, and a bioindicator of air quality, a comprehensive study of lichen diversity in Subang, West Java, has not been conducted. The objective of this study is to analyze the diversity of lichen found in the Curug Sadim natural tourism area, Subang. Data collection was carried out through the implementation of the cruising method at three observation stations. The results of this study indicated the presence of ten lichen species, classified into eight families, Namely Caloplaca sp. (Teloschistaceae), Cladonia sp. (Cladoniaceae), Cryptothecia scripta (Arthoniaceae), Cryptothecia striata (Arthoniaceae), Dirinaria sp. (Caliciaceae), Flavoparmelia caperata (Parmeliaceae), Graphis scripta (Graphidaceae), Leptogium cyanescens (Collemataceae), Parmotrema hypotropum (Parmeliaceae), and Phlyctis sp. (Phlyctidaceae). These lichen species are found attached to substrates such as trees and rocks, and they exhibit various thalus types, including fruticose, crustose, and foliose. The presence of lichen with high variation indicates that the environment of Curug Sadim is relatively clean and supports the survival of bioindicator organisms. These findings are of significant importance in light of their contribution to our understanding of local biodiversity and the potential of lichen as a bioecological indicator in monitoring environmental quality.

Abstract

The primary factor influencing photosynthesis is the presence of chlorophyll pigment. The objective of this study was conducted to identify the impact of leaf age on the rate of photosynthesis and to elucidate the correlation between the level of chlorophyll content in leaves of varying ages and the aforementioned rate. This was achieved through the utilisation of the FLDA (Floating Leaf Disk Array) method. Furthermore, the chlorophyll content measurement method was employed. The FLDA test results demonstrated that old leaves exhibited a higher rate of photosynthesis, potentially due to the elevated chlorophyll level in old leaves relative to young leaves, which averaged ±4,791 mg/ml and ±1,345 mg/ml, respectively. These findings substantiate the existence of a correlation between leaf age and the rate of leaf photosynthesis.

Abstract

Oxidative stress contributes to the development of degenerative and metabolic diseases, and plants rich in phenolic compounds serve as natural antioxidants capable of mitigating its effects. This study comparatively evaluated the antioxidant potentials and phenolic composition of ethanolic leaf extracts of Chromolaena odorata, Anacardium occidentale, and Phyllanthus amarus harvested in Calabar, Cross River State, Nigeria. Standard in vitro assays were employed, including DPPH radical scavenging, ferric reducing antioxidant power (FRAP), hydrogen peroxide scavenging, catalase activity, and total phenolic content (TPC). The results revealed that A. occidentale exhibited the highest DPPH radical scavenging ability (30.93 ± 0.32%) followed by C. odorata (18.10 ± 0.72%) and P. amarus (9.48 ± 0.19%). However, P. amarus demonstrated the highest reducing and enzymatic antioxidant capacities, with FRAP (0.41 ± 0.01 µmol Fe²⁺/g), catalase (4.77 ± 0.12 µmol H₂O₂/min/mg), hydrogen peroxide scavenging (156.60 ± 1.42 µmol/mL), and TPC (2.97 ± 0.50 mg GAE/g). A. occidentale displayed moderate FRAP (0.14 ± 0.002 µmol Fe²⁺/g), catalase (3.30 ± 0.20 µmol H₂O₂/min/mg), hydrogen peroxide scavenging (90.90 ± 1.37 µmol/mL), and TPC (2.53 ± 0.56 mg GAE/g), while C. odorata recorded FRAP (0.28 ± 0.02 µmol Fe²⁺/g), catalase (4.30 ± 0.10 µmol H₂O₂/min/mg), hydrogen peroxide scavenging (116.07 ± 5.06 µmol/mL), and TPC (0.86 ± 0.01 mg GAE/g). A positive correlation was observed between TPC and antioxidant indices across species. The overall results indicate that P. amarus possesses superior total antioxidant capacity, suggesting its potential as a promising natural source of antioxidant compounds for pharmaceutical and nutraceutical applications.

Abstract

Potato (Solanum tuberosum) is a plant that plays an important role as a source of food and carbohydrates for the world community after maize, wheat, and rice. The lack of sufficient demand for low yields in Indonesia can be caused by many factors, one of which is environmental factors, which greatly affect the process of growing potatoes. They are temperature, duration of irradiation, light intensity, growing media, and humidity. Because the growth and process of photosynthesis in plants can be affected by the light factor, therefore our aim in conducting this research was to determine the effect of different light color filters on potato mass, number of shoots, shoot length, number of roots, and root length. The research method used was a completely randomized design (CRD) using 4 (four) treatments. The treatment that was given was P1 on potato shoots which were given a clear plastic filter cover (control), P2 with a blue plastic filter cover, P3 with a plastic filter cover, and P4 which was green. Each treatment was repeated three times for 2 weeks with observations every 2 days. The parameters observed were potato mass, number of shoots, shoot length, number of roots, and root length. The data is then analyzed descriptively using the average and standard deviation. There are differences in the average mass of potatoes, number of shoots, shoot length, number of roots, and root length given different light color filter treatments. The color filter treatment that gives the best results for all parameters is the blue filter.

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

Biosorbents are biological materials used to remove pollutants from solutions passively. Papaya seeds are believed to be a biosorbent candidate because they contain SiO2, which has the potential to act as an adsorbent. Papaya seed adsorbent was made by adding H2SO4 as an activator and using Wantex red as the tested dye. This research aims to determine the potential concentration of papaya seeds as a biosorbent. The analysis used is qualitative, quantitative, and a significance test analysis. The method in this research uses 0.5 g (1%); 1.5g (3%); 2.5g (5%); 3.5 g (7%) of papaya seed biosorbent dissolved in Wantex red dye solution and analyzed using a UV-Vis spectrophotometer. The qualitative color results show contrasting color differences where the most transparent color is the dye added with 1.5 g and 2.5 papaya seed biosorbent, and the UV-Vis spectrophotometer absorbance results show that the best biosorbent mass is 1.5 g and 2.5 g with the highest absorbance power, namely 0.024 mg/g and 0.009 mg/g.
