NORTH AMERICAN COMMISSION ON STRATIGRAPHIC NOMENCLATURE Note 69 - Application for Addition of Subseries/Subepoch to the North American Stratigraphic Code
Authors: Aubry Marie-Pierre , Fluegeman Richard , Edwards Lucy , Pratt Brian R. , Brett Carlton E.
Published: January 2024

Consistency in stratigraphic nomenclature enables communication among scientists both regionally and globally, thus requiring the North American Stratigraphic Code, as presented by the North American Commission on Stratigraphic Nomenclature, to follow international convention. The ratification of three subseries of the Holocene by the International Union of Geological Sciences (IUGS) in June 2018 warrants the integration of subseries among formal chronostratigraphic ranks in the Code. The purpose of making subseries a formal rank is that it aligns the Code with the International Stratigraphic Guide, and establishes the option of using the prefixes super- and sub- for other chronostratigraphic and geochronologic ranks. This is in accordance with the guiding principle of the Code to make it as consistent as possible with international usage and to foster innovations to meet the expanding and changing needs of earth scientists.

Authors: Komissarova E. , Latkov A.
Published: January 2024

The study aims to establish the relationship between the level of digitalization of the national economy and the success of the state’s anti-corruption policy. Clarification of the current methods of quantifying corruption has shown that nowadays the only relevant index reflecting the national corruption indicator is CPI. Based on the analysis of its values for 2018–2022, the leaders among European and Asian countries – Denmark and Singapore – were identified, with which a comparative analysis of the digitalization of Russia’s national economy was conducted using the Digital Evolution scorecard. The results showed that the anti-corruption policies of countries that have completed digitalization or are actively pursuing it are the most successful. This suggests that the digitalization of the national economy is one of the key conditions for increasing the effectiveness of anti-corruption policy. In confirmation, the positive effect of the influence of the national economy’s digitalization on the socio-economic system as a whole and a number of groups of factors that lead to the emergence of corruption were noted.

The current production system of the fashion industry presents environmental, economic and social impacts that go beyond those arising from the manufacturing processes and extend throughout the entire life cycle of the products. In this context, the disposal stage of textile articles is critical, due to the scarcity of alternatives worldwide for managing this waste. This article aims to investigate the main thematic areas that are being addressed in research associated with post-consumer textile waste. The investigation was conducted based on a Systematic Bibliographic Review (RBS), carried out on the CAPES journal portal, using the Systematic Search Flow (SSF) as a methodological procedure. The results point to four main thematic areas of research developed: disposal behavior, textile recycling, practices associated with post-consumer textile waste and post-consumer textile waste management system implemented on a large scale. From the mapping, an imbalance was identified between the number of publications corresponding to the categorized themes, making it possible to observe that research is still mostly positioned at the stage of understanding the problem, which reflects the scarcity of studies that address practical alternatives for management of post-consumer textile waste

Nasopharyngeal dysplasia is a condition of abnormal cellular growth that occurs due to the failure of nasopharyngeal epithelial cells in carrying out cellular adaptation. This condition can occur due to the continuous inhalation of toxic compounds, such as formaldehyde, which has genotoxic and cytotoxic effects that can induce cellular damage. One of the compound activity associated with reducing risk of dysplasia is antioxidant activity. Therefore, it is important to know whether the presence of antioxidant activity affects the occurrence of dysplasia. This study is an experimental study with a post-test only control group design which aims to determine the effect of Non-Antioxidant Feed on the occurrence of nasopharyngeal dysplasia. Testing of the antioxidant activity in feed was carried out using the DPPH assay. There were two groups of experimental animals including the treatment group (fed with Non-Antioxidant Feed) and the control group (fed with SB 11). All animals in each group were induced with 40 ppm formaldehyde by inhalation for 8 weeks and then euthanized using chloroform inhalation for nasopharyngeal tissue extraction. The results of the histopathological examination of the two groups were then statistically tested using the Mann-Whitney U test and obtained a value of P<0.05 (P=0.006), which means that there are effect of feeding Non-Antioxidants Feed on the degree of dysplasia in formaldehyde-induced wistar rats. The results can be associated with the ingredients contained in the feed given, differences in genetic polymorphisms of each subjects, and effect of body weight variations of the rats caused by randomization.

Authors: Surahmaida Surahmaida , Yulianti Cicik Herlina
Published: January 2024

House flies (Musca domestica) are one of the challenging pests that are difficult to overcome and control. Common control methods usually involve the use of chemical insecticides, but a more environmentally friendly alternative is to use plant-based insecticides with repellent properties. Medicinal plants from the Lamiaceae family are famous for their distinctive aroma and are effective in treating pest problems. This research aims to evaluate the potential of cat's whisker leaves and mint leaves as housefly repellent. The repellency test used cotton impregnated with extract concentrations of 2,000 ppm, 4,000 ppm, 6,000 ppm, 8,000 ppm and 10,000 ppm. Exposure time was 30 minutes and carried out 3 times. The repellency percentage is then calculated. The results of the research showed that at concentrations of 2,000 ppm and 4,000 ppm there were still some flies landing, but at concentrations of 6,000 ppm, 8,000 ppm and 10,000 ppm no flies landed. Strong repulsion was observed at concentrations of 2,000 ppm (86.7% for cat's whisker leaf extract and 82.7% for mint leaf extract) and 4,000 ppm (96% for cat's whisker leaf extract and 88% for mint leaf extract). Both extracts showed very strong repulsion (100%) at concentrations of 6,000, 8,000 and 10,000 ppm. These results show that the higher the concentration, the stronger the repellent effect produced. In conclusion, cat's whiskers and mint leaves have potential as active mosquito repellent ingredients, and this research can be the basis for further development as a pest control method, especially against houseflies.

Development and operational activities in KEK Mandalika can increase sedimentation of waters caused by erosion of construction material activities, this have an impact on coral reef ecosystems. Coral reef ecosystems have several important roles in support life of various aquatic organisms, Damage to the coral reef ecosystem directly and indirectly, sooner or later will threaten the sustainability of the use of these resources (social economy) and the safety of the community. Observations were conducted in KEK Mandalika coastal at 6 observation points less than 10 m. The results showed that the highest percentage of live coral cover was found in Kuta Mandalika coastal at PIT 4 area (30%, damaged category, moderate status). While the lowest percentage of coverage was at PIT 5, which was 2% (damaged category, bad status). Overall the percentage of coral cover in the Kuta Mandalika area is included in the damaged category. One of the reasons is because at the lowest tide on the beach, the volume of water is very small so that many hard corals are exposed to solar radiation. This limits the types of hard corals that can grow in the intertidal zone of Mandalika coastal. Genus diversity at this location is low, ranging from 0.0782 to 0.1288. Several genera of the Nephtheidae family dominate the observation sites and form colonies of the same genus with a fairly large distribution. The average value of environmental parameter measurements in the Mandalika coastal is included in the good category for soft coral habitat and growth.

Bacteria have an important role in providing essential nutrients for plants in dry land through various beneficial working mechanisms. One of the main mechanisms is the involvement of bacteria in nutrient cycles, such as the nitrogen cycle. The aim of this research was to determine the type and ability of bacteria in the rhizosphere of neem (Azadirachta indica) to fix nitrogen. The method used in this research is an exploratory descriptive type. The results of the isolation carried out from the rhizosphere of neem (Azadirachta indica) taken from the East Lombok area of Jerowaru sub-district, 5 samples were obtained with the code LO, where 2 isolates had the ability to fix nitrogen, namely LO3 and LO4. This is proven by using NFB media where there is a change in the color of the media from green to blue, and quantitatively using a spectrophotometer with results of 1,112 ppm and 2,156 ppm, respectively. The results of the molecular identification of the potential bacteria, namely LO4, using the BLAST method at the GenBank data base (NCBI), show that LO4 is the closest relationship to the species Lysinibacillus fusiformis strain SMC303. The results above show that rhizobacteria isolated from neem have the potential to be developed as a biofertilizer that can be applied to future cultivated plants.

Phosphate solubilizing rhizobacteria are microorganisms that live in the rhizosphere of plants and have the ability to increase the availability of phosphate in the soil, thereby reducing dependence on chemical fertilizers which are harmful to the environment. This research aims to isolate rhizosphere bacteria from Lamtoro plants and test their ability to dissolve phosphate. Screening the ability of these bacterial isolates was carried out using Pikovskaya media and quantitatively using a spectrophotometer. The test results showed that there were 3 isolates, namely KLU13, A2 and KLS1, which had IKF values in the medium category. Meanwhile, the other 4 isolates had abilities in the low category (isolates A1, A31BK, A3BB and A3). The results of quantitative tests with a spectrophotometer showed that there was an increase in dissolved phosphate from day 2 to day 6. Isolates KLU13, A3 and KLS1 dissolved the highest phosphate on day 6 with values of 14.65 ppm, 14.81 ppm and 10.32 ppm respectively. It can be concluded that the isolate obtained from the Lamtoro rhizosphere which grows in the dry areas of Lombok Island has the potential to be developed as a biofertilizer in the future.

The use of pineapple fruit extract as an immunostimulant in aquaculture has become the focus of significant research in efforts to improve the immune systems of aquatic organisms, especially farmed fish. Pineapple fruit extract, which contains bromelain, has attracted attention as a potential natural solution to improve the immune response of fish against pathogens and disease. The main aim of this review is to evaluate the extent to which the use of pineapple as an immunostimulant is effective in improving the immune system of fish or other aquatic organisms in an aquaculture context. This article uses literature study methods from several national, accredited national journals and reputable international journals. Literature study is the process of searching, collecting and analyzing various sources of information relevant to a particular topic. Pineapple extract contains bromelain, which has immunomodulatory and anti-inflammatory properties. It can improve the fish's immune response and reduce inflammation, helping to improve fish health. The use of pineapple fruit extract can reduce dependence on antibiotics in the treatment of sick fish, which is in line with global efforts to overcome antibiotic resistance and environmental impacts. With the right efforts, the use of pineapple fruit extract as an immunostimulant in aquaculture has the potential to increase the productivity and sustainability of the aquaculture industry, as well as reduce dependence on antibiotics and synthetic chemicals. Therefore, further research and development of best practices in the use of pineapple fruit extract in aquaculture are necessary steps to realize its potential as a more environmentally friendly and sustainable alternative.

Published: January 2024

Long beans (Vigna sinensis L.) have the potential to be developed because they have high economic value. However, this is not supported by a decrease in production availability for 5 years. One of the efforts made is to improve fertilization and pruning techniques. The aim of this research is to determine the interaction of bocation and pruning on long bean production. This research used a Randomized Block Design with a factorial pattern of 2 factors with 3 levels of treatment, namely: Factor I = Bokasi (B) consisting of B0 = No Bokasi (control), B1 = Bokasi solid cow dung 10 tons /haB2 = Bokasi dung solid pigs 10 tons/ha and B3 = liquid bokasi with a concentration of 1400 cc liters of water-1 plot-1 and Factor II = pruning (P) which consists of P0 = no pruning, P1 = pruning 21 HST and P2 = pruning 35 HST. The research results found that there was an interaction between giving bokasahi fertilizer (1,400 cc plot-1) and pruning time (21 HST) which had a very real influence and gave the best results on the research variables.

Groundnut (Arachis hypogaea L.) is a crop plant that has an essential role in several food industries because it has high nutritional content, especially protein, and fat. One of the limiting factors in efforts to increase peanut production is the disturbance of plant-disrupting organisms (PDO). Preventive efforts that can be made to minimize yield losses due to pest problems in peanut plants include inventory activities and direct observations in the field. This study aims to assess the biological aspects of important diseases in peanut plants as an initial step in making pest control decisions. Observations were conducted on a 748 m2 farmer's field in Purangi Village, Sendana Sub-district, Palopo City. The field was divided into two main plots, without using maize barrier (B0) and using maize barrier (B1), and six subplots (P1-P6). Groundnut disease symptoms were determined through identification based on the signs and symptoms of the attack. Disease symptoms found in peanut plants were chlorosis, necrosis, spotting, mosaic, curling, and wilting. Mosaic and necrosis symptoms were the most dominant symptoms with the highest frequency of occurrence at 50 times, while chlorosis, curling, stripes, and wilting symptoms were the lowest symptoms with the least frequency of occurrence in peanut plantations at under 25 times.
