Abstract

Soil pollution is an environmental problem caused by hazardous substances such as heavy metals that can damage ecosystems. One method used to monitor soil conditions is biomonitoring using organisms as bioindicators. Fungi have the potential as bioindicators due to their ability to respond to environmental changes through variations in growth and community diversity. This study aims to determine the role of fungi as bioindicators in soil pollution biomonitoring using a literature review method. Data were collected from various scientific sources and analyzed descriptively. The results show that soil pollution reduces fungal diversity and leads to the dominance of more tolerant species. In addition, fungi can absorb and accumulate heavy metals through biosorption. Therefore, fungi are effective bioindicators for assessing soil pollution levels.

Abstract

Muntingia calabura (kersen) is a tropical plant with high adaptability that reproduces generatively through seeds. This study aimed to determine the generative reproduction process of kersen through natural seed germination and to observe the early growth and adaptive response of the plant after being transplanted into planting media. The method used was observation with a descriptive approach. The study was conducted for approximately 14 days, using young plants resulting from natural germination as the research objects. The procedures included collecting seedlings, transplanting them into planting media, and observing plant growth. The results showed that the plant did not exhibit significant height growth, remaining at approximately 15 cm, and the number of leaves decreased from 8 to 6 due to leaf yellowing and abscission. This condition indicates the occurrence of transplant shock after relocation to new planting media. However, the plant maintained an upright stem, indicating its ability to survive. Therefore, generative reproduction through seeds is the main mechanism of kersen propagation, although early plant growth is strongly influenced by environmental conditions and adaptation processes.

Abstract

Casuarina trees (Casuarina sp.) are a key element of coastal flora, significantly contributing to the stability of shorelines and the equilibrium of ecosystems. Nevertheless, research in bioecology conducted in natural settings can present risks to ecosystems if ethical considerations are not thoroughly observed. This research intends to examine the implementation of bioethical principles in bioecological studies concerning Casuarina trees at Kuranji Beach, located in West Lombok. The study utilized a qualitative descriptive method through observational techniques and ethical evaluation without any quantitative data collection. Findings reveal that bioethical principles can be incorporated through approaches that do not harm the environment, maintain the integrity of habitats, and foster ecological awareness during research efforts. Moreover, the research highlights possible infringements of bioethical standards observed in field studies where there is a deficiency in ethical consciousness. Consequently, the inclusion of bioethical principles is crucial for ensuring that research activities are performed in a responsible and sustainable manner, especially in coastal ecosystems that are particularly susceptible to ecological disturbances.

Abstract

Nephrolepis biserrata is a species of fern commonly found in tropical environments with high humidity. This plant plays an ecological role in maintaining environmental humidity and increasing vegetation diversity. This study aims to determine the collection and preservation techniques for Nephrolepis biserrata plants found in Turida Village, Sandubaya District, Mataram City. The research method used was direct field observation through exploration and sampling. Samples were identified based on morphological characteristics, including roots, stems, and leaves. Preservation techniques were carried out using herbarium methods, including cleaning, pressing, drying, labeling, and storing the specimens. The results showed that Nephrolepis biserrata was found growing on damp and shady walls. The collected samples were still small, so they did not yet show sori on the undersides of the leaves. Proper collection and preservation techniques are important to maintain the quality of the specimens as learning and research materials.
