Abstract

Gourami is a type of freshwater fish that is widely distributed in Indonesia, including in the waters of Kualuh Leidong District, North Sumatra. However, the kinship relationship between gourami species in the region has not been widely studied. Therefore, this study aims to analyze the kinship relationship of several gourami species found in the waters of Kualuh Leidong using the DNA fingerprint method. This study uses a molecular characterization method with several stages, namely collecting fish samples, isolating and extracting DNA, amplifying DNA using Polymerase Chain Reaction (PCR) with several primers, electrophoresis, and analyzing data using NTSYS software. Sampling was carried out by collecting specimens from the waters of Kualuh Leidong, including four types of gouramis, namely Trichopodus trichopterus, Trichopodus pectoralis, and Helostoma temmincki. The electrophoresis results showed that the DNA of the gourami fish could be amplified with primers OPA 02, OPC 02, and UBC 456, but not amplified with primer OPA 20. The DNA banding pattern obtained consisted of polymorphic and monomorphic bands with varying locus sizes. Jaccard coefficient analysis showed a high level of kinship (>70%), with the species Trichopodus pectoralis having a similarity of 0.78, Trichopodus trichopterus 0.76, and Helostoma temmincki 0.71. The results of this study can be used as a basis for the conservation and management of gourami fish resources in the waters of North Sumatera.

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.
