Abstract

Carbondioxide (CO?) is one of the greenhouse gases that contribute to climate change and global warming. Indoor and urban CO? concentrations can affect air quality and human health. Pasar Wisata Bojonegoro is a central economic hub with high mobility and trading activities, which may increase CO? emissions. This study aims to identify peak CO? concentration hours in the area and compare them with the air quality standards set by the WHO. A quantitative research method was used, involving direct observation and measurement over 7 (seven) days at a single observation point. The results show that on weekdays, the peak CO? concentration occurred between 16:00 and 16:59 WIB, reaching 424 ppm, while the lowest concentration was recorded between 18:00 and 18:59 WIB at 351 ppm. On weekends, the peak concentration was 441 ppm between 16:00 and 16:59 WIB, while the lowest was 113 ppm between 21:00 and 21:59 WIB. Several weekdays recorded CO? concentrations exceeding the WHO standard (310–330 ppm), with the highest reaching 466 ppm. However, CO? concentrations on Thursdays and weekends remained within the acceptable limits. The conclusion of this study shows that the results of CO? concentration on weekdays (Monday, Tuesday, Wednesday, Friday) exceed the quality standard with CO? concentrations of 466 ppm, 462 ppm, 413 ppm, and 433 ppm. Meanwhile, on weekdays (Thursdays) and weekends, it meets the quality standards with CO? concentrations of 217 ppm, 243 ppm, and 267 ppm.

Abstract

Pakcoy comes from the Brassicaceae family, known for being rich in nutrients, including vitamins A, C, K, as well as fibres and minerals. Onion skin contains bioactive compounds that have the potential to be organic fertilizers, while sugarcane bagasse is agricultural waste that can be used as an alternative planting medium. This study aims to determine the effect of soaking shallot skin using sugarcane bagasse planting media for the growth of Pakcoy (Brassica rapa L.). This study was conducted in Tuntungan II village using the factorial Randomized Block Design (RAK) method consisting of two factors and 3 replications with 3 treatment levels. The parameters observed included relative growth rate, net assimilation rate, number of leaves, total leaf area, wet weight and dry weight of pakcoy plants. The results showed that the combination of onion skin soaking gave a significant effect on all red parameters (B2: 250 ml/500 ml water) and bagasse gave a significant effect on the net assimilation rate of 2-3 MST and 4-5 MST in the treatment of 500 gr/polybag bagasse but on other parameters the control treatment was better. Thus, the provision of onion skin soaking as organic fertilizer with bagasse planting media on the growth of pakcoy plants can be applied in agriculture, because this treatment has a significant effect on all treatments.

Abstract

Unconserved springs tend to be polluted by various organic wastes. Accumulation of organic waste causes water to be contaminated with coliform bacteria, thus reducing water quality. Biofilter technology can be applied to reduce the number of coliform bacteria. This study aimed to determine the ability of BioFilter K4Ser-Col (moringa seeds, rice husks and kesambi charcoal) to reduce total coliform in spring water. The research location was at the Riumata Spring, Nekbaun village, West Amarasi sub-district, Kupang district. The work consisted of preparing the BioFilter K4Ser-Col media, taking water samples, and testing MPN coliform. MPN coliform testing was done twice before and after the water filtration on the BioFilter K4Ser-Col media. The study's results showed a decrease in the MPN value before and after filtering. The MPN coliform value before filtering was 1600 MPN/100 mL. After filtered water on the BioFilter K4Ser-Col media, it decreased to 23.23 MPN/100 mL. This value had met the national water quality standards for the class I category based on PP No. 22 of 2021. Thus, the use of BioFilter K4Ser-Col media could greatly reduce the number of coliform bacteria in water.

Abstract

Abiotic stress is an environmental condition that is unfavorable for plants such as drought, salinity, heavy metal contamination and nutrient deficiencies. Prolonged abiotic stress causes the stability of plant cell organelles to be disrupted, thereby inhibiting plant growth and development. This research aims to examine the role of membrane transport in responding to environmental stress, especially abiotic stress, and the implications for plant growth and development. The research method used was a literature study using meta-analysis techniques assisted by prism diagrams in analyzing 14 relevant scientific articles from various national and international journals. The analysis was carried out descriptively on the results of previous research. The results show membrane transport has a role in increasing plant resistance to abiotic stress. Cell membrane structure consisting of lipids, proteins and carbohydrates has been proven to increase plant safety from environmental stress. So it can be concluded that membrane transport has a role in mediating tolerance, resistance, and resolving plant stress conditions through maintaining cellular homeostasis. Implications of this research can help expand knowledge about how plants respond to unfavorable environmental conditions through membrane transport mechanisms and can be basis for developing plant varieties are resistant to various forms of environmental abiotic stress.

Abstract

This study aims to optimize the production of cellulase enzyme by the cellulolytic fungus Aspergillus niger using rice husk powder (Oryza sativa Linn.) as substrate. Cellulase enzymes have important roles in various industrial applications, including the bioconversion of lignocellulosic waste into high-value products such as bioethanol, pulp, paper, and animal feed. The utilization of rice husk as a substrate offers economic and environmental advantages due to its abundant availability, low cost, and ability to reduce the volume of agricultural waste. The research method used a quantitative experimental approach to evaluate the effect of fermentation parameters, such as pH, temperature, and incubation time, on enzyme production. A. niger isolates were developed on carboxymethylcellulose (CMC) media to ascertain their cellulolytic capacity, with measurements of biomass, pH, temperature, and enzyme activity. The results showed that the biomass of A. niger increased from hour 0 to hour 96 at pH 4.5 to 5.5, and temperature 29.5°C to 30.5°C. The optimum condition for enzyme production was found at pH 4.5 and temperature 30.5°C, with the highest enzyme activity reaching 0.736 U/mL. These findings suggest that optimization of cellulase enzyme production from rice husk not only improves enzyme production efficiency, but also contributes to more sustainable waste management.

Abstract

Visual representation is important for scientific communication. One form of visual representation is a diagram. When representing diagrams, there are still students who fail to read labels or titles, misunderstand color codes, or follow arrows in the wrong direction. The aim of this research is to analyze students' ability to visually represent and interpret the Bryophyta life cycle diagram. The visual representations analyzed are internal and external visual representations. This study uses a descriptive approach involving one biology teacher and 33 students from grades X, XI, and XII at one of the high schools in the city of Bandung. Data were obtained through worksheets and semi-structured interviews. Internal visual representation is obtained from the activity of reading and re-representing the available diagrams, while external visual representation is obtained from the activity of redrawing the Bryophyta diagram based on one's own understanding. Assessment is conducted based on three main indicators: the number of phases, the sequence of phases, and the accuracy of phase descriptions. Scores are converted into percentages and categorized into five levels of proficiency: very good, good, moderate, poor, and very poor. The analysis results show that the internal visual representation of students in grades X, XI, and XII falls into the poor category, while the external visual representation of students in grades X and XI falls into the good category, and grade XII falls into the moderate category. The analysis also shows a relationship between visual representation and prior knowledge. These findings have important implications for the development of visual-based learning and mapping students' difficulties in understanding diagrams.

Abstract

Complex Basic Biology course materials and learning processes that still use manual textbooks make it difficult for students to follow the learning process on campus. Learning videos are audio-visual media used to deliver educational or training materials in an interesting and effective way. Through learning videos, the delivery of information becomes more interactive, attracts attention, and makes it easier to understand complex concepts. Biology learning videos are made with the aim of making it easier for students to understand the material so that they can increase their interest and motivation in learning biology, especially Basic Biology courses. This study involved 76 undergraduate biology students taking a Basic Biology course. It used both qualitative and quantitative methods. Data was collected through a questionnaire where students evaluated the learning videos. The validity test showed a significant value of 0.00 < 0.05, and the reliability test gave a value of 0.074 > 0.07, meaning the questionnaire was valid and reliable. The results of the data analysis showed that more than 80% of students agreed and strongly agreed that the biology learning videos helped them understand the material better. In conclusion, learning videos can increase students' interest and motivation in studying biology, especially in Basic Biology courses.

Abstract

Mitochondria have long been known as the main energy producers in eukaryotic cells through oxidative phosphorylation. However, the development of molecular biology has revealed its multifaceted role in the regulation of apoptosis, cellular metabolism, calcium homeostasis, and immune responses. This study uses a meta-analysis approach to explore the various functions of mitochondria by integrating data from various scientific studies. Literature searches were conducted through scientific databases, namely publish or perish. Data obtained 300 with relevant studies consisting of 24 articles, and 1 book according to the inclusion criteria. The results of the analysis show that the complexity and contextual nature of mitochondrial function, which depends on cell type and physiological conditions, indicate its adaptability in maintaining cell survival. Mitochondria are multifunctional organelles that not only play a role as a center for energy production through oxidative phosphorylation, but are also involved in various important cellular processes, namely as a central regulator of cell vitality, controlling processes ranging from survival to programmed cell death. In addition, mitochondrial dysfunction is associated with various pathological conditions, including neurodegenerative diseases, metabolic disorders, and cancer. This comprehensive review provides new insights into the importance of mitochondria in both normal and pathological states and emphasizes the importance of a deeper understanding of mitochondrial mechanisms for the development of targeted therapies.
