Abstract

The results of real experiments according to the Wheeler scheme prove the influence of the future on the behavior of elementary particles in the present. Interpretation of the results of experiments on the basis of ideas about the interaction of bodies in time leads to the following conclusions: 1. The force of inertia corresponds to the general definition of force as a measure of interaction. 2. Newton's second law becomes a consequence of the third, 3. The problem of correspondence between gravitational and inertial mass has been solved, 4. General expressions for the force of inertia leading at low speeds to the classical formulas of accelerated motion and circumferential motion are given. Within the framework of the developed method, an expression is given for the force of interaction, which takes on a real value, at the moment when the body moves at a speed exceeding the speed of light. The expression for this force differs in sign from the force of inertia. A hypothesis is put forward that the nature of such forces is a temporary interaction of charge. The application of Einstein's formula for a moving mass in this case organically explains the existence of charges of different signs. Modulo, both forces are equalized in a range of speeds close to the speed of light. It is supposed to use the adopted approach to describe the nature of elementary particles.

Abstract

In the Democratic Republic of Congo (DRC), cassava occupies a particularly important place in the diet of rural households that produce it. 27 local cassava cultivars collected in 08 agricultural production basins in the Bengamisa region were evaluated agro-morphologically. The objective was to analyze the phenotypic diversity of local cassava cultivars and their structuring on the basis of 20 variables selected from cassava descriptors. The collected local cassava cultivars were evaluated in a randomized complete block design with 27 treatments and four replications in Bengamisa. Descriptive analysis of qualitative characters revealed polymorphism between local cassava cultivars. Principal Component Analysis (PCA) showed that the 20 morphological descriptors considered were the most relevant (CP ≥30%) to explain the morphological variability between local cassava cultivars. The ascending hierarchical classification (CAH) made it possible to obtain 4 morphogroups that are relatively undifferentiated compared to the extent of the morphological space between the different agricultural production areas. Discriminant factor analysis (DFA) was carried out using the 3 quantitative production variables (number of tuberous roots per plant; weight of tuberous roots per plant; and plant height at harvest) studied in 4 groups defined by the hierarchical ascending classification and allowed through the Wilks Lambda test to reveal that the 3 descriptors or variables have a very highly significant contribution (p-0.000). These groups offer a great possibility of choosing parents for the creation of improved varieties of cassava with high yield potential and adapted to different agricultural production basins in the Bengamisa region; Tshopo; DR CONGO.

Abstract

The study examined the impact of three cassava leaf harvesting methods on the growth and leaf yield of the Obama II variety in Kisangani. The three methods were light picking (CL), moderate picking (CM) and coarse picking (CG). Results showed that plant diameter was not affected by harvesting method, but plant height and number of tender shoots were. Rough harvesting produced the tallest plants with the most tender shoots. Yields of fresh cassava leaves varied according to harvesting method, ranging from 5.36 to 12.27 t/ha, with rough picking giving the highest yield. However, light picking had the highest rates of leaf removal (63.8%) and wilting (55.4%), followed by moderate picking (CM: 49.6% rate of leaf removal and 39.0% of wilting), while coarse picking had the lowest rates of leaf removal (21.6%) and wilting (18.6%).

Abstract

Chrysanthemum (Chrysanthemum sp.) is an ornamental plant that produces flowers that have high economic value. Chrysanthemum flowers have the potential to be developed because they are in great demand by the public in terms of beautiful shapes and colors. One of the important stages in chrysanthemum cultivation is seeding. The main problem in chrysanthemum farming is the attack of white rust caused by a fungus (P. horiana) starting from seedling to harvesting. The use of plant extracts as alternative pesticides has many advantages and benefits. Plants that have the potential to be used as botanical pesticides include mimosa, garlic and galangal. This study aims to determine the effectiveness of giving the mimosa, garlic and galangal extracts in chrysanthemum plant nurseries to suppress white rust disease caused by the fungus P. horiana. This research was carried out using an experimental design, namely a completely randomized design (CRD) which consisted of 4 (four) treatments and 4 replications, namely K (control), P1 (20% mimosa extract), P2 (20% garlic extract), and P3 (20% galangal extract). Based on the results of observations of the symptoms of white rust (P. horiana) the upper surface of the leaves at first in the form of yellow spots which gradually changed color to dark brown, then on the lower surface of the leaves can be seen the presence of pustules that are pink, and long Over time the pustules will get bigger and then turn white. The highest percentage of attacks was in control (K), 10.08%; the garlic extract treatment at 20% (P2) at 4.27%, then followed by the 20% galangal extract treatment (P3) at 3.33%, and the mimosa extract treatment 20% (P1) 0.96%. The results showed that the use of extracts of Putri malu, garlic and galangal was able to suppress white rust disease (P. horiana) in chrysanthemum plant nurseries, with the best treatment in suppressing white rust disease (P. horiana) which was mimosa extract 20% (P1 ) with attack percentage: 0.96%, followed by galangal extract (P3): 3.33% and garlic extract (P2): 4.27%. In accordance with the results of the research that has been carried out, it is necessary to carry out further research on the use of Mimosa Extract, Garlic and Galangal against white rust (P. horiana) in chrysanthemum plant nurseries with higher concentrations and in other varieties of chrysanthemum seedlings.

Abstract

The primary objective of this study is to explore sustainable alternatives to address the accumulation of waste resulting from the sisal exploitation in South Amboasary. Laboratory tests involving 8,000 g of defibration residues mixed with 1,600 g of inoculum over 69 days produced 355 liters of biogas, equating to 335 L/kg of dry matter with a methane content of 58% and a lower calorific value of 20,807 kJ/Nm³. These results suggest that biomethanation can valorize the 212,630 tons of sisal waste available annually, potentially replacing the 2,030 m³ of diesel consumed each year and meeting the domestic fuel needs of 16,575 households with eight members each. Additionally, a production of 137,800 tons of compost is projected to prevent the emission of approximately 7,000 tons of CO₂-equivalent toxic gases into the atmosphere. The technical feasibility studies for infrastructure implementation and project organization address several issues: local treatment of organic waste, creation of local jobs, energy independence, agricultural sustainability, and economic development.

Abstract

This paper delves into environmental challenges in Madagascar's Ikopa Watershed, focusing on the impact of climate disruptions and human activities on terrestrial and aquatic ecosystems. Employing a multidisciplinary approach, the research is examining the intricate interplay of geological, climatic, and human-induced factors, exploring their implications for sustainable water resource management. The study has employed representative sampling, surveying 386 households, and has combined it with field data collection and an evaluation of local perspectives on environmental risks. The results have identified four main forms of environmental degradation: water and wind erosion, biological, and water degradation. These phenomena have significant implications for water availability and quality, as well as local agricultural activities. Additionally, the research has classified households into two groups based on their exposure to climate variability, emphasizing the need for tailored adaptation strategies to address specific environmental challenges. The findings underscore the importance of local adaptation initiatives, such as sustainable land management and community awareness, to enhance resilience against environmental risks. Conclusively, the paper emphasizes the importance of ongoing and customized water resource management in the Ikopa Watershed, taking into account local perspectives, adaptation strategies, and future environmental challenges.

Abstract

The present work aimed to evaluate the variation of dry matter, organic matter and crude protein in the vegetative phase of four varieties of Brachiaria brizantha (Xaraes, Piata, Marandu and Locale) in forage cultivation. After field experimentation in a complete random block system, and laboratory analyses, the results obtained show that the dry matter content increases from the beginning tillering stage to the end tillering stage and varies according to variety. The highest dry matter content is recorded in the local variety at the late tillering stage. The crude protein content also varies depending on variety and phenological stage, the protein contents are higher at the full tillering stage in the varieties Xaraes (17.34%), Locale (15.8%) and Marandu (14.2%), while the Piata variety reaches its highest protein content from the early tillering stage (13.8%). Overall, the Xaraes variety is more protein-rich, its average protein content in the vegetative phase is 15.3%. Thus, the Xaraes variety is economically more interesting than the others, protein being the most expensive component in livestock feed. This is why this variety would be indicated to be popularized with a view to large-scale exploitation in the Kisangani region. However, additional bromatological analyzes are necessary before any decision.

Abstract

Protection is a safeguard in the electric power system installed in the electric power distribution system, power transformers, electric power transmission, and electric generators used to protect the electric power system from electrical disturbances or overloads by separating the disturbed part of the electric power system from the existing electric power system. Not disturbed so that the uninterrupted electrical system can continue to work. Failure of the protection system at the KG02 and KG 180 substations at PT PLN (Persero) UP3 Tanjung Priok when short circuit currents occurred on the phases on the consumer side resulted in the PMT (Power Breaker) of the feeder tripping. This resulted in widespread outages which had a negative impact on the image of PT PLN (Persero) UP3 Tanjung regarding network reliability. To find out the cause of the protection system failure, CT (Current Transformer) checks were carried out on the three substations. At the KG02 substation, the 345KVA CT power contract is installed with a ratio of 10/5 and class 5P10 with a fault current of 2861A. At the KG180 substation, the CT is installed with a ratio of 100/5 with class 5P10 with a fault current of 6547A. From the results of the data from the two substations above, the protection system failure occurred in the current transformer which was saturated when a fault current exceeded 2861A and 6547A. To overcome protection failures at the two substations above, it is necessary to add a CT Ring 800/5 with class 5P20, with the test results being a reference for improving the protection system so that similar failures do not happen again.

Abstract

This work investigates the relationship between spiritual interconnection and quantum field theory (QFT) by adding a holistic parameter Λ to the potential function V(ϕ, Λ)=0.5m2ϕ2+ΛV0ϕ4. Higher levels of interconnection boost quantum correlations since the study shows that the expected value of spin correlation <S1⋅S2> is directly related to Λ. The enormous influence of non-linear interactions in quantum systems is highlighted by numerical calculations that demonstrate a linear relationship between Ϋ and spin correlation. These results imply that holistic variables can modulate quantum entanglement, giving empirical credence to spiritual beliefs on the unity and oneness of all reality. The ramifications of the discovery extend beyond quantum technologies, where optimizing the entanglement qualities for computing, cryptography, and sensing applications could be achieved by adjusting the holistic parameter. Furthermore, this study promotes an integrated knowledge of the cosmos by bridging the gap between reductionist and holistic scientific paradigms. To gain a deeper understanding of how reality is interconnected, future research should explore the impact of holistic parameters on various quantum domains and promote interdisciplinary cooperation. This all-encompassing method aligns with the metaphysical aspects of life, enhancing both spiritual and scientific knowledge.

Abstract

Spodoptera frugiperda is a new pest that entered Indonesia around 2018 and acts as the main pest that causes young corn plants to be damaged and experience growth problems. It is known that there is a natural enemy, namely the parasitoid Trichogramma sp. which can attack S. frugiperda eggs. The research method can be carried out by experimenting with the development and multiplication of the parasitoid Trichogramma sp. in the laboratory using a previously cultured population of C. cephalonica eggs as a host. The results showed that the multiplication of the egg parasitoid Trichogramma sp. with alternative host C. cephalonica can be done in the laboratory. Biological development in the form of the life cycle of the parasitoid Trichogramma sp. can be known based on observations, namely the egg stage is around 14-15 hours, the first instar larva stage is 22 hours, the second instar is 24 hours, the third instar is 25 hours, the fourth instar is 26 hours, the pupa stage is 28 hours, the lifespan of adult female insects is 10-12 days while the male 10-11 days. Percentage of parasitization of Parasitoid Trichogramma sp. the population of the S. frugiperda pest egg group in the field was quite high, ranging from 68.5 – 87.3 percent with an average of 76.5 percent.
