Influence of Inorganic Nitroge N-Nutrients on Copper Toxicity in Anacystis nidulans and Cyanophage As-I Resistant Mutant
Authors: Gupta S. L.
Published: May 2024

The effect of different nitrogen sources on growth and copper toxicity was studied in the unicellular cyanobacterium Anacystis nidulans and Gyanophage AS-1 resistant mutant (An/AS-1). The mutant An/AS-1 was characterised by slow growth rate but was more senstitive to copper than its parent. In both the strains, the presence of high nitrate concentrations, which supported better growth of algae, reduced the algicidal effect of copper. However, other inorganic nitrogen sources such as nitrite and ammonium caused more inhibition and reduced the specific growth rate.

Authors: Putri Jasmine Safira Az'zahra , Nurwati Nunung , Yunita Desi
Published: May 2024

Single parent families are form of incomplete family, where one parent is fully responsible for the education and character building of the child. This role vacancy often triggers deviant behavior in children. This study aims to explain communication and children’s deviant behavior in single parent families. This research uses literature study research method with social deviation theory by Edwin H. Sutherland. There are several research results obtained from this study. First, the communication established in single parent families has not been effective. Second, the factors that cause children’s deviant behavior in single parent families are caused by two things, namely disappointment with the situation in the family and the environment of peers who tend to behave deviantly. Third, the role of communication in preventing children’s deviant behavior in single parent families is a major foundation in preventing children’s deviant behavior. This study concludes that authoritative communication is the most appropriate application in single parent families to overcome communication problems in the family. Apart from that, good communication can have a significant impact on parents’ relationships to be able to control and supervise children to prevent deviant behavior.

IMPLEMENTATION OF SCAFFOLDING STRATEGY TO IMPROVE CHEMICAL LITERATION CAPABILITIES AND SELF-EFFICACY THROUGH USE OF THE PROBLEM-BASED LEARNING MODEL AT COLLOID MATERIAL
Authors: Hammasa Harsono , Bakti Iriani , Kusasi Muhammad
Published: May 2024

The scaffolding strategy is designed to address difficulties in understanding materials. By using scaffolding, it is possible to improve chemical literacy and self-efficacy. The teaching of colloidal material has not represented abstract material adequately. Therefore, to enhance chemical literacy and self-efficacy, a student-centered learning model is needed, namely the problem-based learning (PBL) model. This study aims to determine the differences in chemical literacy and self-efficacy in the scaffolding strategy with the PBL model, the relationship between chemical literacy and self-efficacy, and student responses to the scaffolding strategy with the PBL model.The research method used was quasi-experimental with a pretest-posttest non-equivalent control group design. Purposive sampling was employed for sample selection. The study used descriptive and inferential analysis, comparing dependent variables in the experimental class using the scaffolding strategy with the PBL model and the control class using the PBL model, with a sample of 73 students.The results indicate a significant difference in chemical literacy and self-efficacy between the scaffolding strategy with the PBL model and a positive response from students in terms of chemical literacy and self-efficacy after treatment. The Pearson correlation (rxy) between chemical literacy and self-efficacy was 0.674, indicating a strong correlation. The R2 value was 0.454, meaning that self-efficacy contributes 45.4% to chemical literacy. Students showed a positive response to the scaffolding strategy with the PBL model compared to without the scaffolding strategy. Therefore, the implementation of the scaffolding strategy with the PBL model can enhance chemical literacy and self-efficacy by providing students with assistance in understanding materials and problem-solving. The application of the scaffolding model in PBL activities should be modified using supportive media with characteristics similar to those in this study.
POTENTIAL OF DAYAK ONION SKIN (ELEUTHERINE PALMIFOLIA) EXTRACT AS AN ALTERNATIVE INDICATOR FOR ACID BASE TITRATION PRACTICUM
Authors: Elfa Noor , Hidayah Rina Nur
Published: May 2024

Synthetic indicators such as phenolphthalein are used during acid-base titrations to determine the end point of the titration. These indicators are not environmentally friendly and the price is high. To overcome this, it is necessary to study the potential of natural indicators available in the environment, one of which was Dayak onion skin which has not been utilized after the tubers have been taken as an anti-cancer herbal medicine. The aim of this research was to determine the potential of Dayak onion skin (Eleutherine Palmifolia) as a natural indicator in acid-base titrations. The sampling collection of Dayak onions was done randomly in the city of Palangka Raya, Central Kalimantan. The method used in this study employed experimental techniques in the chemistry laboratory of FKIP ULM with the following steps: 1) Maceration of smoothed Dayak onion skin with 96% ethanol for 1, 2 and 3 days 2) Qualitative test of anthocyanin, color test with buffer pH 1-14, 3) Absorption measurement with a UV-Vis spectrophotometer at a wavelength of 200 - 400 nm, 4) Application of the extract as an indicator in acid-base titrations. The results showed that the optimum maceration time was on day 3 with an absorption of 4,520 at a wavelength of 380 nm. The application on the HCl – NaOH titration with a titration end point volume of 9.11 mL showed a color change from yellow to straw yellow, while the comparison indicator PP had a volume change of 8.57 mL with a color change from colorless to pink. The CH3COOH – NaOH titration gave a result of 11.43 mL and the PP indicator was 11.01 mL. For the NaHCO3 – HCl titration, the end point volume of the titration was 9.93 mL with a straw yellow – yellow color change and the MO indicator comparison was 10.27 mL with an orange – red color change. From the results of this research, there was a significant color change at the end point of the titration, so it can be stated that Dayak onion skin extract had the potential to be an alternative indicator in acid-base titration practice so that it can be a solution in reducing chemical pollution in the environment.

Authors: Nur Islamiyah Eka Fitria , Dewanti Binar Ayu , Santoso Agus
Published: May 2024

In order to address the lack of reliable scientific literacy assessment tools in many schools, it became necessary to develop new instruments. Unfortunately, most teachers had not previously conducted comprehensive scientific literacy assessments or used assessment tools that followed independent curriculum assessment guidelines. As a result, this study was undertaken to create a valid and reliable scientific literacy assessment tool for junior high school students. The assessment tool utilized five scientific literacy indicators: understanding phenomena, explaining phenomena scientifically, using scientific evidence, solving problems, and identifying scientific problems in the earth and solar system. The 4D research and development method was employed in this study, with the development stages simplified to 3D. Research instruments included validation sheets and scientific literacy tests. The final product is a scientific literacy assessment tool consisting of 16 essay questions. Results from content/expert validity testing by material and language experts were 0.83%, and the empirical validation results of the 16 essay questions as a whole were deemed valid. Additionally, reliability testing yielded a value of 0.960, indicating very high reliability. Testing the hypothesis on the left side showed that at least 61% of students possessed scientific literacy abilities, with the same proportion found to be at the developing and advanced stages. However, 11% of students were still in the beginning stages, indicating that they had not yet met the learning objectives criteria.
Optical axis control system invariant to the character of disturbance
Authors: Zbrutsky Oleksander , Osokin Vladyslav
Published: May 2024

The task of synthesizing an optimal system of automatic control of the optical axis of a camera with guaranteed accuracy, which is invariant to the nature of disturbances, is considered. Disturbances in this context can be different and not limited. The process of creating a mathematical model of the control system and solving the mathematical synthesis problem using the inverse dynamic model approach is shown. The results of the study demonstrate the mechanism of ensuring the quality of the automatic control system during the compensation of disturbances, and also indicate the features of the system structure. A special method for creating the corrective effect necessary to compensate for disturbances is discussed in the context of the approach of the state variable of the automatic control system to the limit of permissible values. An important result is the discovery of a new mathematical structure - an algebraic-differential equation (for a system with one degree of freedom) or a system of such equations (for a system with several degrees of freedom), which corresponds to this structure of the automatic control system.
A technical vision system for controlling the movement of a quadcopter
Authors: Savenko Larysa , Bobkov Yuryi
Published: May 2024

In this paper, based on the analysis of possible options for the autonomous movement of a quadcopter along a predetermined trajectory, the combination of a technical vision system (TVS) and IMU is proposed.
Flying through a system of navigation landmarks was applied to solve navigation tasks during autonomous movement along a predetermined route using TVS. There are several approaches to implementing TVS to control UAV movement, depending on the accepted landmark system and the features of the route definition. For the previous description and further detection of navigation landmarks in the TVS image, the application of feature extraction methods is proposed, as it enables the selection of objects of different structures, including natural landmarks.
A block diagram of a quadcopter control system with the application of TVS is developed. A methodology for calculating the main parameters of the TVS units is proposed, based on the specified requirements for the accuracy of the quadcopter's heading determination by navigation landmarks.
The paper also proposes an algorithm for controlling the movement of a quadcopter using a system of visual navigation landmarks which define the flight route. After finding the image of the next navigation landmark in the TVS frame according to the selected feature system, its center and position in the frame relative to the quadcopter's heading are determined. The obtained data is used to determine and change the direction of the movement of the quadcopter by changing the yaw angle, which is transmitted to the control system.
The suggested approaches may be useful in solving various problems of using TVS for controlling UAV movement.
Semi-supervised inverted file index approach for approximate nearest neighbor search
Authors: Bazdyrev Anton
Published: May 2024

This paper introduces a novel modification to the Inverted File (IVF) index approach for approximate nearest neighbor search, incorporating supervised learning techniques to enhance the efficacy of intermediate clustering and achieve more balanced cluster sizes. The proposed method involves creating clusters using a neural network by solving a task to classify query vectors into the same bucket as their corresponding nearest neighbor vectors in the original dataset. When combined with minimizing the standard deviation of the bucket sizes, the indexing process becomes more efficient and accurate during the approximate nearest neighbor search. Through empirical evaluation on a test dataset, we demonstrate that the proposed semi-supervised IVF index approach outperforms the industry-standard IVF implementation with fixed parameters, including the total number of clusters and the number of clusters allocated to queries. This novel approach has promising implications for enhancing nearest-neighbor search efficiency in high-dimensional datasets across various applications, including information retrieval, natural language search, recommendation systems, etc.

Novel modified kernel fuzzy c-means algorithm used for cotton leaf spot detection
Authors: Paithane Pradip , Wagh Sarita Jibhau
Published: May 2024

Image segmentation is a significant and difficult subject that is a prerequisite for both basic image analysis and sophisticated picture interpretation. In image analysis, picture segmentation is crucial. Several different applications, including those related to medicine, facial identification, Cotton disease diagnosis, and map object detection, benefit from image segmentation. In order to segment images, the clustering approach is used. The two types of clustering algorithms are Crisp and Fuzzy. Crisp clustering is superior to fuzzy clustering. Fuzzy clustering uses the well-known FCM approach to enhance the results of picture segmentation. KFCM technique for image segmentation can be utilized to overcome FCM’s shortcomings in noisy and nonlinear separable images. In the KFCM approach, the Gaussian kernel function transforms high-dimensional, nonlinearly separable data into linearly separable data before applying FCM to the data. KFCM is enhancing noisy picture segmentation results. KFCM increases the accuracy rate but ignores neighboring pixels. The Modified Kernel Fuzzy C-Means approach is employed to get over this problem. The NMKFCM approach enhances picture segmentation results by including neighboring pixel information into the objective function. This suggested technique is used to find “blackarm” spots on cotton leaves. A fungal leaf disease called “blackarm” leaf spot results in brown leaves with purple borders. The bacterium can harm cotton plants, causing angular leaf blotches that range in color from red to brown.
Survey of image deduplication for cloud storage
Authors: Chaudhari Shilpa , Aparna Ramalingappa
Published: May 2024

Increased growth of real-life communication has motivated the creation, transmission, and digital storage of vast volumes of images and video data on the cloud. The explosive increase in virtual/visual image data on cloud servers requires efficient storage utilization that can be addressed using image deduplication technology. Even though the virtual and visual image properties are different, the existing literature uses a similar approach for deduplication checks, which motivated us to consider both image types for this review. This article aims to provide a detailed survey of state-of-the-art visuals as well as virtual image deduplication techniques in a cloud environment, summarizing and organizing them by developing a five-dimensional taxonomy for analysing the features and performance with several non-overlapping categories in each dimension. These include: 1) location of applying deduplication; 2) image feature extraction; 3) time of application; 4) image data partitioning strategy; 5) involvement of user dataset level. Existing image deduplication techniques are categorized into two main categories based on whether the technique involves security. A comparison of techniques is discussed across a set of functional and performance parameters. The current issues are highlighted with the possible future directions to motivate further research studies on the topic.
A comprehensive survey on load balancing techniques for virtual machines
Authors: Sansanwal Suman , Jain Nitin
Published: May 2024

Cloud computing is an emerging technique with remarkable features such as scalability, high flexibility, and reliability. Since this field is growing exponentially, more users are attracted to fast and better service. Virtual Machine (VM) allocation plays a crucial role in cloud computing optimization; hence, resource distribution is not impacted by machine failure and is migrated with no downtime. Therefore, effective management of virtual machines is necessary for increasing profit, energy-saving, etc. However, it could utilize the virtual machine resources more efficiently because of the increased load, so load balancing is more concentrated. The predominant purpose of load balancing is to balance the available load equally among the nodes to avoid overloading or underloading problems. The present study conducted an extensive survey on virtual machine placement to describe the application of prediction algorithms and to provide more efficient, reliable, high response, and low overhead VM placement. Furthermore, the survey attempted to overview the challenges in load balancing in VM placement and various ideas of state-of-the-art techniques to resolve the issues.

Authors: AlAli Rommel , Wardat Yousef , Saleh Shoeb , Alshraifin Nedal
Published: May 2024

Background: The STEM education system has garnered significant interest due to its innovative approach in creating a multidisciplinary and integrated knowledge structure that connects science, technology, engineering, and mathematics, and allows students to apply scientific knowledge in a comprehensive and holistic manner. Consequently, evaluating the teaching methods of teachers in accordance with STEM standards is critical. This assessment should take into account various educational objectives, including cognitive, skill-based, and emotional aspects.

Purpose: This study aimed to evaluate the creative teaching practices of mathematics teachers for gifted students according to STEM standards.

Method: The study applied the descriptive analytical method and developed a rating scale for evaluating creative teaching practices based on STEM standards, verifying the psychometric properties in several ways. The study sample consisted of 64 teachers of mathematics for gifted students.

Results: The results showed that the degree of application of creative teaching practices by the teachers of gifted students according to STEM standards was at the moderate level in three domains: planning, implementation, and assessment.

Conclusions: Despite the importance of achieving integration for STEM, the actual teaching practices of teachers of the gifted according to these standards were generally average and did not reach acceptable and ambitious levels.
Fitting the Crab Supernova with a Gamma-Ray Burst
Authors: Ruffini Remo , Sigismondi Costantino
Published: May 2024

A panorama of the current historiography on the Supernova of 1054 is outlined. Shklovsky (1968) [1], and Murdin (1985) [2] show how the interpretation of this phenomenon converged on a Su-pernova event. Here we reconsider the historical data, assuming a Gamma-Ray Burst (GRB) as its source. A Supernova correlated with the GRB explains well the fading time observed by the an-cient Chinese astronomers, in daytime and in night time, while the GRB power-law explains the present X-rays and GeV emission of the Crab. On the ground of recent understanding of the first episode of binary driven Hypernova GRB (BDHN GRB) in terms of the collapse of a ten solar masses core, we propose the possible identification of the real Supernova event at earlier time than Chinese chronicles. This work allows a new understanding of the significance of historical astronomical observations, including a fireball, due to gamma-rays air shower observation, and a plague of acute radiation syndrome, documented with several thousands of victims in the Eura-sian area (Egypt, Iraq and Siria).

Metabolic and Functional Interaction of H2S and Sucrose in Maize Thermotolerance through Redox Homeodynamics
Authors: Li Xiao-Er , Zhou Hong-Dan , Li Zhong-Guang
Published: May 2024

Hydrogen sulfide (H2S) is a novel gasotransmitter, sucrose (SUC) is both cellular energy and signaling molecule. However, their signaling interaction in maize thermotolerance is poorly known. In this study, using maize seedlings as materials, metabolic and functional interaction of H2S and SUC in maize thermotolerance was investigated. Data show that under heat stress survival rate and tissue viability were increased by exogenous SUC, while malondialdehyde content and electrolyte leakage were decreased by SUC, indicating SUC could upraise maize thermotolerance. Also, SUC-upraised thermotolerance was enhanced by H2S, while weakened by inhibitor (propargylglycine) and scavenger (hypotaurine) of H2S and SUC-transport inhibitor (N-ethylmaleimide). To figure out underlying mechanism of H2S-SUC interaction-upraised thermotolerance, redox parameters in mesocotyls of maize seedlings were measured before and after heat stress. The data display that activity and gene expression of H2S-metabolizing enzymes were up-regulated by SUC, whereas H2S had no significant effect on activity and gene expression of SUC-metabolizing enzymes. Besides, activity and gene expression of catalase, glutathione reductase, ascorbate peroxidase, peroxidase, dehydroascorbate reductase, monodehydroascorbate reductase, and superoxide dismutase were reinforced by H2S, SUC, and their combination under non-heat and heat conditions in varying degrees. Similarly, content of ascorbic acid, flavone, carotenoid, and polyphenol was increased by H2S, SUC, and their combination, whereas production of superoxide radical and hydrogen peroxide level were impaired by these treatments to different extent. These results imply that the metabolic and functional interaction of H2S and sucrose exists in the formation of maize thermotolerance through redox homeodynamics.

Purpose: The deterioration of oral function has been getting much attention as “Oral frailty”. This study evaluated the change in tongue pressure, one of the objective items of oral frailty, to examine the relationship between body position and tongue pressure. Methods: This study was prospective, observational study in a single-center. The participants were categorized by Clinical Frailty Scale (CFS). Tongue pressure was measured in the following positions: dorsal, sitting, and sitting with plantar grounding. Differences in tongue pressure between CFS and between body positions were statistically analyzed. Results: A significant decrease in tongue pressure was demonstrated in CFS4 compared to CFS3. Furthermore, in CFS5 and CFS6, tongue pressure decreased in the sitting po-sition compared to that in the dorsal position and recovered to the dorsal level with plantar grounding. Conclusions: Tongue pressure decreased as the progression of frailty. It decreased by sitting, and this decrease was alleviated by plantar grounding.

A shrimp specimen of the genus Neocaridina Kubo 1938, originally from Asia, was collected for the first time in a natural marine environment in Pernambuco, Brazil. This represents the first record of this genus in the South American continent. Morphological characteristics and mitochondrial and nuclear DNA sequences (COI, 16S, 18S, and H3) of the specimen were compared with other species of Neocaridina, enabling its identification as Neocaridina davidi. Finding this freshwater species native to mainland China in a marine environment was surprising. Based on prior findings in other locations, the most likely hypothesis for this unusual occurrence is that the shrimp may have been released intentionally or unintentionally into the environment by an aquarium hobbyist.

The study aims to analyze the consistency of the quality of fried peas with statistical process control aids. Samples were taken daily for 28 days from a nut frying business. The quality of samples including color, free fatty acid, peroxide value, and organoleptic is tested daily with 5 repetitions. Quantitative quality consisting of color, moisture content, free fatty acids, and peroxide value is analyzed with SPC while organoleptic quality is analyzed with PCA. Analysis with SPC results in an upper control limit and a lower control limit of 68.6%; 25;4; 43.7 and 37.7; 8,7; 22.6 for L*, a*, and b*, 2.275% and 2.072% for moisture content, 0.628% and 0.145% for free fatty acids, and 1.075 mEqO2/kg and 0.079 mEqO2/kg for peroxide value. Based on the upper control limit and the lower control limit, pea quality is inconsistent for variable moisture content, free fatty acids, and peroxide value. Analysis of PCA color, moisture content, free fatty acids, peroxide value, and sensory products did not show certain grouping and clustering patterns, which meant the samples were relatively the same as each other. Even though the variables of water content quality, free fatty acids, and peroxide value of fried peas are inconsistent, they are not detected by panelists. The causative factors of quality deviation can be known with certainty by examining each factor listed in the fishbone diagram. In addition, monitoring also needs to be done routinely and closer to the production process to find out exactly the cause of product quality deviations.

Tofu is one of the foods that are very liked by the people of Indonesia. However, because it is easily damaged, there are still many tofu manufacturers who use formalin with the aim of extending the shelf life of products and avoiding losses. Based on this, the purpose of this study was to test the effectiveness of basil leaf extract solution with different concentration variations and soaking duration in reducing formalin content in white tofu, as well as observing changes in white tofu protein levels before and after treatment. In addition, the study will also conduct sensory tests of color, suppleness and aroma. This research method applies a factorial Complete Randomized Design (RAL) involving two main factors. The first factor is the concentration of basil extract solution (K), which has three levels (K1:10%, K2:20%, and K3:30%). The second factor is the duration of immersion (L), which also has three levels (L1: 30 minutes, L2: 60 minutes, and L3: 90 minutes). Each variation of the treatment was repeated three times, and tests were carried out on formalin content, protein levels, and sensory tests covering aspects such as color, texture, and aroma. The findings of this study indicate that the ability of the basil leaf extract solution to the highest decrease in formalin was 66.61% and an increase in protein content of 71.19%, namely in the treatment concentration of 30% basil leaf extract solution with immersion time 90 minutes (L3K3), with the results of the sensory test of texture 4.6 (like), color 4.1 (like), and aroma 3 (dislike).

Enhancing post-harvest handling is crucial to boost productivity, preserve product quality, and enhance the competitiveness of food commodities. One effective approach to maintain product quality is by using edible coating, and in this case, alginate-based edible coating has been employed. The alginate-based edible coating exhibits a deficiency in terms of its inadequate mechanical properties. The addition of starch could improve the mechanical properties of alginate-based edible coating. Jackfruit seed starch has the potential to valorize as a cost-effective source of starch. Jackfruit seed flour has unique starch characteristics related to acid resistance, thermal properties, and mechanical properties when compared with starch from other sources. This study aims to optimize the concentration of alginate and jackfruit seed flour in the preparation of tomato edible coating using Response Surface Methodology (RSM). The effect of alginate concentration (1-2% b/v) and jackfruit seed flour concentration (1-2% b/v) on mass loss (%) and color difference (ΔE) were investigated. The optimum condition was obtained at an alginate concentration of 1.5% b/v and jackfruit seed flour concentration of 1.0% b/v with the resulting tomato quality value of mass loss of 5.43% and color difference (ΔE) of 0.70.
