Abstract

According to research published in the Journal of Applied Phycology, algae have the ability to produce biofuels with five times higher energy efficiency compared to soybean plants, making it a highly efficient and sustainable option for renewable fuels. The goal of this research is to use biotechnology to create biofuels from algae as a renewable energy. This study used a laboratory experimental design with a quantitative approach. Population: Microalgae or green algae that have high potential in lipid production, such as Chlorella vulgaris or Spirulina platensis, which are commonly used in biofuel research. Sample: Several species of algae were selected to test their effectiveness as biofuels, including genetically engineered species and natural species as a comparison. The results of the ANOVA analysis showed significant differences in lipid levels between treatment groups. The results of the T/Post-hoc test confirmed that the genetically engineered species had higher lipid levels, supporting the efficiency of biofuels. The regression results showed a strong positive correlation (R² = 0.68), which supports other studies that found that microalgae can produce biomass in a relatively short time with a controlled environment, making it efficient for large-scale biofuel production. The conversion efficiency of lipids to biofuels reached 85.5%, indicating that the transesterification method used in this study is very effective in converting algae lipids to biodiesel. The use of biotechnology in the production of biofuels from algae has great potential as an efficient and sustainable renewable energy source.

Abstract

The global pharmaceutical industry is constantly looking for new resources that can be used to develop bioactive ingredients to produce more effective and innovative medicines. One resource that has attracted the attention of researchers is marine microorganisms (UGM, 2017; Wiganti, 2022). The ocean, which covers more than 70% of the Earth's surface, is an ecosystem rich in biodiversity, including microorganisms that are unique and rarely found in terrestrial environments. This research aims to explore and identify marine microorganisms that have potential in the production of bioactive materials for pharmaceutical applications. Based on the results of this study, only Extract I showed significant inhibition against Staphylococcus aureus, while Extract II had almost no inhibition. Table 2 shows the results of the study indicating that the inhibition of seaweed extracts was absent. Gracillaria sp. seaweed extracts evaporated through a rotary vacuum evaporator and seaweed extracts evaporated through an oven had no inhibition. This study showed that bioactive compounds prepared through extraction using vacuum evaporator had greater inhibition of Staphylococcus aureus. This suggests that marine microorganisms can be a source of bioactive ingredients for the pharmaceutical industry.

Abstract

Climate change is a major threat to food security, especially for farmers in vulnerable areas facing the challenges of climate change. This study aimed to modify the plant genome to increase tolerance to extreme climatic conditions such as drought and high temperatures using genetic engineering methods based on CRISPR-Cas9 technology. Transgenic and control plants were grown in a laboratory experimental design with a quantitative approach. The results showed that the transgenic plants consistently outperformed the control plants under drought, high temperature, and low nutrient conditions. The transgenic plant showed a growth rate of 15.2 and average productivity of 25.7, higher than the control (12.3 and 19.1). Under high temperature conditions, the increase in productivity was even greater, reaching 33.2%, indicating that the inserted HSP gene successfully protects important proteins from heat stress damage. Genetic modification through the expression of genes such as DREB1A, HSP70, and PHR1 was shown to increase plant resistance to environmental stress. With these findings, biotechnology provides a real opportunity to build more adaptive and sustainable agricultural systems, supporting global food needs amid the intensifying challenges of global warming. This research is very relevant in answering the big challenge in the future, which is how to ensure biotechnology can be utilised sustainably to meet the world's growing food needs, without compromising ecosystems and biodiversity.

Abstract

This study aims to develop more advanced and efficient spectrometric methods for heavy metal analysis in urban environments. This research uses an experimental quantitative approach to develop and optimise spectra-based analysis methods. The results showed that heavy metal concentrations in industrial area soils far exceeded environmental quality standards, with Pb reaching 128.5 mg/kg, Cd 2.4, Cr 96.3, and Hg 0.21, exceeding the set quality standards. In water samples, river water near industrial areas was highly polluted for all parameters, and Pb (0.42 and 0.008 mg/L) far exceeded the safe limits. This study shows that industrial areas have significant levels of heavy metal pollution in soil, water and air compared to residential areas. Therefore, better management of industrial effluents, development of efficient pollution monitoring and detection technologies, and implementation of environmentally friendly transport strategies are urgently needed to mitigate the risks of pollution to human health and the environment.

Abstract

Rapid industrial growth has significantly contributed to environmental pollution, particularly through hazardous waste disposal. Industrial waste, including heavy metals and toxic organic compounds, poses a major challenge for sustainable environmental management. Improper management of this waste can lead to contamination of water, soil, and air, threatening human health and ecosystems (Bagaskara, 2023; Supraptini, 2002). This study investigates the potential of bioremediation using microbes for industrial waste management and identifies factors influencing its effectiveness. Conducted as an experimental laboratory study, the research tests various microorganisms known for their bioremediation capabilities, such as Pseudomonas, Bacillus, and Aspergillus.Analysis of contaminated soil revealed lead (Pb) levels at 63.1 mg/kg, exceeding the livestock toxic limit of 10–30 mg/kg. The growth index (GI) for the inoculum treatment increased by 84.3% to 136.7% over a sixty-day incubation period, while the control treatment showed minimal changes (88.8% to 111.7%). These findings indicate that optimal incubation conditions and appropriate microbial selection can enhance soil quality, making it safer for plant growth and less harmful to the environment. Expanding bioremediation practices could significantly mitigate the adverse effects of industrial waste on environmental pollution. Overall, this research highlights the viability of microbial bioremediation as an effective strategy for managing industrial waste and improving ecological health.
