RANCANG BANGUN PENGUPAS KULIT KACANG MENGGUNAKAN MIKROKONTROLER ATMEGA 8 DAN PANEL SURYA 20 WP
Authors: Andi Hendra Jaffri , Yanie Ahmad , Siregar Lisa Adriana
Published: May 2024

To support the production process of a home industry or large industry, tools or machines are needed. For example, in an industry that produces peanut bread, there is a process of peeling the peanuts, both the shells and the shells, which takes a lot of time and labor. To help overcome these problems, this research designed a semi-automatic peanut shell peeler. The machine works as a grinder where the roasted nuts are put into a grinding mill that has been spaced so that the peanuts that enter will be peeled. The machine is driven by an electric current that is to run a permanent magnet DC motor and sensor. For that we need a source of DC electricity. As a supplier of electricity, NRE energy is utilized, namely sunlight obtained by a 20WP solar panel and equipped with a backup battery to store electric current. It is hoped that the designed machine can support productivity and can be used in villages or remote areas where there is no PLN electricity.

Authors: Almeida de Oliveira Jennifer , Rezende Ferreira Rubens , Cambraia Parreira Ricardo , Mendes Filho Daniel
Published: May 2024

Atualmente a poluição sonora tem atingido proporções enormes devido ao crescimento populacional e consequente multiplicação das fontes de ruído. Essa problemática se manifesta de forma evidente nas residências, nas vias públicas, nos veículos, nos locais de trabalho, nos espaços teatrais e nos estabelecimentos gastronômicos. Além dos ruídos audíveis, existem também sons em frequências inaudíveis que podem ser igualmente prejudiciais à saúde, o que torna imperativo investigar essas interferências e como elas resultam em alterações que impactam a saúde do indivíduo. Assim, para compreender os efeitos da poluição sonora e como essa interfere no organismo provocando o surgimento de distúrbios neuropsiquiátricos e cardíacos, propôs-se a elaboração de umarevisão  narrativa. Para o desenvolvimento desse artigo, utilizo-se a base de dados da plataforma PubMED com os descritores que foram selecionados a partir de uma pesquisa no DeCS/MeSH:: “poluição sonora”, “poluição sonora e sistema cardiovascular” e “poluição sonora e sistema nervoso”. Por meio da pesquisa realizada, observou-se que a poluição sonora, direta ou indiretamente, afeta a saúde humana. Embora o impacto direto no sistema auditivo, como surdez, seja bem estudado, a influência nos sistemas cardiovascular e neurológico necessita de mais consideração e pesquisa.Apesar dessa dificuldade de dados na literatura,  foi possível identificar problemas que podem surgir devido à poluição sonora, como: aumento da pressão arterial, AVC, doenças mentais, demência e distúrbios no desenvolvimento neurológico. Assim sendo,, a partir de uma discussão abrangente sobre essa pesquisa, é possível traçar medidas de contenção ao ruído excessivo, pois as medidas de saúde coletiva vigentes tendem a negligenciar os riscos relacionados aos ruídos ambientais.

Published: May 2024

The main aim of this small-scale questionnaire study involving 35 participants was to validate a research instrument which is to be used in the author’s main study on Hungarian EFL teachers’ attitudes towards the incorporation of controversial issues (CI) into their lessons. The other aims of the study were to reveal how often teachers teach CI, what CI they teach, what background variables influence their decisions to teach CI and what stance they take when dealing with CI in class. After an extensive review of literature on global education and teaching controversial issues, some insight is given into the validating process and some preliminary results are provided regarding the research questions. Findings suggest predominantly positive attitudes from the participants. Based on the results, it seems that teachers deal with a wide range of controversial topics quite frequently, mostly because they take their students’ interest into consideration.
Assessment of Learning in The Hungarian Education System With a Special Focus on Language Teachers’ Views and Practices
Authors: Hubai Katalin , Lázár Ildikó
Published: May 2024

This article aims to discuss some of the most important aspects of assessment of and for learning in Hungarian public education. The first research focus is on analyzing the current National Core Curriculum and the education act as well as other important governmental and ministerial decrees, including the requirements of a teaching degree and those of teacher promotion as these also influence teachers’ attitudes to and practices of assessment. The second research focus is a review of empirical studies on teachers’ views and practices of classroom assessment in Hungary with a special focus on language teachers. Results seem to indicate that although the official documents regulating assessment of student learning follow recent educational trends in Europe, most subject teachers tend to insist on the traditional “teach-to-the-test and then give a written or oral exam” approach. On the other hand, the reviewed studies also show that language teachers feel the need to experiment more and more often with new assessment tools in their classroom.

Published: May 2024

Since the reform and opening up in the 1980s, in the context of cultural exchange between China and the West, Chinese culture, art, and ideological concepts have undergone tremendous changes. Under the influence of Western painting, the development of oil painting art has further explored and studied modernist painting. At the same time, under the influence of Western modernist painting art, Chinese oil painting art has also shown a phenomenon of a hundred flowers blooming, such as the diversification of artistic styles and the diversification of painting language types, thereby creating the birth of various new painting schools. In the context of globalized art and culture, contemporary Chinese oil painting has also begun to go global. However, the development of contemporary Chinese oil painting is still criticized by the art of easel painting and photorealistic painting. Faced with the booming art market and the diversification of evaluation standards, how to understand the current situation and trends of contemporary oil painting art development is a question worthy of our in-depth research and reflection.

Published: May 2024

Ultraviolet radiation is one of the physical concerns of the environment. Several nations have thus moved research attention to this area. This research work aimed at measuring the solar UV-B absorbance on outdoor workers in Nsukka metropolis, South Eastern Nigeria. An LS125 multi probe UV Light Meter with UV- B sensor was used to measure the UV-B irradiance across five study locations representing the various occupations, viz: Barracks (mechanics), Opi (Farmers), Ogige (Traders), Zik’s flat (motor park workers) and Onuiyi (Bricklayers). A UV-Vis spectrophotometer was used to determine the change in the optical absorbance of polymer polysulphone dosimeters. Result shows that UV-B Irradiance was highest at solar noon across the study locations. The dosimeter placed on the head received the highest dose of UV- B radiation at the study locations. The values of the cumulative UV-B exposure of the dosimeters placed on the body parts at the study sites were higher than the occupational exposure limit of 30J/m2 for a 6.5-hour exposure time for both the eye and skin recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The AIC and BIC values shows that the logarithm regression model outperformed the other models tested. This work therefor sets a reliable baseline data for solar UV-B radiation monitoring in Nsukka, South Eastern Nigeria and also recommend that protective clothing be worn carrying out daily activities during peak solar UV-B radiation hours,
Evaluation and Impact Assessment of Meteorological Drought Characteristics over West Africa
Authors: Ogolo Emmanuel O. , Ojo Olusola S. , Akinwande Dolapo D.
Published: May 2024

When a region receives little precipitation for an extended period of time, droughts occur. The environmental and socioeconomic effects it has make it one of the most devastating natural disasters that can happen to a location. For the purpose of enhancing early warning systems and lowering the risk of disasters caused by drought, research into the effects of meteorological drought characteristics on a location is crucial. Therefore, this study uses the Standard Precipitation Index (SPI) and Standard Precipitation Evapotranspiration Index (SPEI) to assess the effects of meteorological drought characteristics over West Africa. The study area includes West Africa's Saharan, Sahelian, and Sudanese climate zones, and Copernicus Service provided the meteorological information (temperature and precipitation). The data was based on four monthly time scales (3, 6, 12, and 24) and covered 42 years (1979-2021). The data were analyzed and the characteristics of the drought were assessed using SPI and SPEI. According to the results, there was extreme drought between the years 1982 to 1985 and year 2021. However, 1982 was the year with the highest incidence of drought, across nearly all the stations. Additionally, it was found that location 4 experiences drought continuously from 1982 to 2021, whereas all other locations experienced absence of drought for a short period of time.  Comparing the SPI and SPEI results, SPI produced results for the drought analysis that were comparable to those of SPEI for each of the monthly time scales for all locations.  Majority of the locations will likely experience drought every seven to ten years, with location 4 possibly experiencing at least a mild drought every year. Finally, this study suggests that, in light of the time-scales analysis and drought classification for each location, SPI and SPEI represent the most suitable measures for the region's drought monitoring.

This work explores the ramifications of introducing the Howusu Metric Tensor into the theoretical framework of Riemann's Acceleration within spherical polar coordinates, aiming to deepen our comprehension of gravitational interactions. Bridging the gap between traditional Cartesian coordinates and spherical polar coordinates, the research navigates the challenges posed by rotational symmetry to seamlessly integrate Riemann's Acceleration into the latter. The Howusu Metric Tensor emerges as a novel mathematical construct tailored to the intricacies of spherical polar coordinates, enabling a refined representation of spacetime curvature. The Results which are Riemann's acceleration in light of the Howusu metric tensor in spherical polar coordinates and consequently a generalization of the Newton's equations of motion showcase the modified Riemann's Acceleration equations in spherical polar coordinates, revealing subtle differences when compared to conventional Cartesian coordinates. Comparative analyses underscore the impact of the Howusu Metric Tensor, both quantitatively and qualitatively, offering insights into the altered dynamics of gravitational forces. This signifies a paradigm shift in our approach to gravitational theory, showcasing the potential of the Howusu Metric Tensor to unravel novel insights and broaden the horizons of theoretical physics. The findings not only advance our understanding of gravitational interactions but also set the stage for further exploration and refinement in the ever-evolving landscape of theoretical physics.

Published: May 2024

Occupational safety encompasses a range of practices adopted to protect the health and safety of employees. In the construction and industrial sectors, employees may be exposed to various risks such as falls, impacts, temperature changes and the effects of chemical substances. For this reason, personal protective equipment (PPE) is an important element for protecting employees against risks. The effective use of equipment such as a hardhat, mask, and vest makes an important contribution to the prevention of occupational accidents and health problems by ensuring the safety of employees. This study conducted three separate experiments investigating the potential of deep learning methods on occupational safety. In the first experiment, the YOLOv5n and YOLOv8n models were trained on the same data set with ten classes, and their performance was compared. In the second experiment, the YOLOv8n model was trained on a 2-class dataset to examine how the number of classes affected the model's performance. As a result of the experiments, it was seen that it emphasized the potential of deep learning and object detection methods to quickly and effectively monitor and evaluate the use of personal protective equipment.

This experiment was conducted to determine the concentration of digestible (DE), metabolizable (ME), and net energy (NE), and to develop prediction equations for DE and ME in coconut co-products (CCP) fed to growing pigs. The CCP used were copra meal (CM), protein enriched copra meal (PECM), and white copra (WC) obtained from the different sources in the Philippines. Twenty-two growing barrows (PIC L337 × C24; initial BW 18.74 ± 0.91 kg) were individually housed in metabolism cages that allowed for a total but separated collection of feces and urine. Pigs were arranged in a replicated 11 × 3 Youden square design with 11 dietary treatments at three periods each. A basal diet that contained 96.26% corn, and ten additional diets consisting of 70% basal diet and 30% CCP were formulated. All diets have the same proportion of corn and other ingredients. Fecal, urine, diet, and CCP samples were analyzed for gross energy (GE) using bomb calorimetry. The DE and ME concentrations of CCP diets and ingredients were calculated. The NE of diets and ingredients were estimated using the prediction equation (NE = 0.870 × ME – 442). The DE, ME, and NE concentrations differed (P < 0.001) among CCP and ranged from 1,843 to 3,284, 1,666 to 3,211, and 1,008 to 2,352 kcal/kg DM, respectively. The DE (3,193 kcal/kg DM), ME (3,074 kcal/kg DM), and NE (1,774 kcal/kg DM) concentrations of CM was greater (P < 0.001) than PECM (1,859, 1,717, and 1,052 kcal/kg DM, respectively) but with similar DE (2,657 kcal/kg DM), ME (2,562 kcal/kg DM), and NE (1,787 kcal/kg DM) of WC. However, the DE, ME, and NE of WC was greater (P < 0.001) than PECM. A positive correlation (r ≥ 0.72; P < 0.05) was observed between the DE and ME and acid detergent fiber (ADF) in 8 CCP (excluding WC samples). The DE and ME concentrations in CCP may be predicted using the following equations: 1) DE = -715.30 + 101.42 × % ADF (R2 = 0.52, RMSE = 403.85, P = 0.04); and 2) ME = -983.16 + 106.13 × % ADF (R2 = 0.51, RMSE = 427.42, P = 0.04). In conclusion, DE and ME concentrations differ among CCP sources fed to growing pigs. Moreover, DE and ME values in CCP can be predicted using ADF as independent variable.

In this study, plant growth promoting rhizobacteria (PGPR) and plant growth promoting fungi (PGPF) were isolated from soil adhered to the roots of herbs. PGPR and PGPF isolates were selected for producing microbial inoculant as a starter culture for bio-fertilizer production. The screening of PGPR and PGPF was performed using the spread plate technique on the selected medium. Total plant growth promoting microorganisms (PGPM) were composed of 72 isolates, nitrogen-fixing microorganisms: 39 isolates, phosphate-solubilizing: 11 isolates, and potassium-solubilizing: 22 isolates. Two bacterial isolates, S-K7-2 and S-P7-1, had the highest plant growth promoting abilities, and a fungus isolate, Di-K7-2, was able to produce the greatest amount of IAA, which was 45.17 μg IAA equivalent/ml. The isolates were tested on hairy basil seed germination. Treatment using microbial cell dissolved in sterile distilled water had the greatest potential for stimulating the growth of seed and presented 145.26% of GI, followed by 82.87% where the treatment was with IAA standard. The study of the effect of PGPR and PGPF on hairy basil growth found that the highest biomass was shown in treatment 3, peat supplemented bacteria (S-K7-2, S-P7-1), which indicated that rhizobacteria immobilized on peat was able to enhance the growth of hairy basil and had better potential for promoting plant development compared with chemical fertilizer treatment.

This study was undertaken to determine long-term soil organic matter (SOM) accumulation dynamics from added mango leaf litter (MLL) into tilled (MT) and non-tilled soil (MnT) through integrated field experiment (bio-physico-chemical edaphic properties) and system dynamics modeling. Field data shows that the coarse (Lf) and fine (Fn) fractions of SOM have no significant difference (p > 0.05) between MT and MnT during the dry season. In contrast, there is a significant difference (p < 0.01) in the Fn fraction between MT and MnT during the wet season. The total N, available P, exchangeable K, as well as the collembola, bacteria, and fungi in the soil were also assessed. Of these parameters, the available P and exchangeable K have a significant difference between the MnT and MT during the dry season. In comparison, the total N and collembola significantly differed during the wet season. The results of the field experiment were used in the parametrization to build the SOM accumulation model. The 20-year simulation showed that the incorporation of MLL into the soil through tillage increased SOM from 3.09% to 3.13%, with an average of 2.78 ± 0.018%. In the non-tilled orchard, SOM also increased from 3.09% to 4.23%, with an average of 3.59 ± 0.035%. This SOM level can sustain the fertility and productivity of the mango agroecosystem. The increase in SOM is accounted for by the coarse fraction both in tilled and non-tilled plots. Given the foregoing, with minimum tillage, mango orchards can be developed into crop-based systems.

Security in the field of Information Technology is the defense of digital information along with its assets against internal and/or external malicious and accidental threats. To secure such valuable information, cryptography is used. A cryptography or encryption algorithm is the process of transforming sensitive data into confounding data in such a way that the person or the machine with a key can decode the hidden information. Among these algorithms is the Vigenere matrix. In this article, a hybrid approach is used in the encryption algorithm. This approach implements the matrix manipulation principle and Base94 encoding algorithm. In order to measure the performance of the proposed algorithm, the Avalanche Effect is used. The result of the study shows a significant high avalanche effect compared to the traditional Vigenere cryptosystem.

Learning Java programming can be tedious and difficult for beginners. In addition, traditional teaching methods can be insufficient in acquiring an understanding of the entire Java programming concepts, enhanced coding abilities, and improved problem-solving skills. Lack of resources, files being easily deleted in computers, and poor academic performance were some of the identified problems that led to students’ very low competence in Java programming. This paper aims to develop an E-Learning system that would help solve or at least minimize the problems of students in learning Java programming. The expected users of the developed system are the students learning Java programming, the Instructors who will be managing the lessons, and the designated Administrator who will be in-charge in managing the accounts of students and instructors. The proposed E-Learning system for Java programming was evaluated by both the Information Technology (IT) experts and the students as the end-users. The evaluation results in general revealed that the developed E-learning for Java Programming is acceptable among IT experts and end-users.

Millions of people around the world fall within the age group of 35 and above; having fluctuating lifestyles, increased exposure to blue light, and a faster-depleting ozone layer that enhances entry of UVA and UVB rays in the skin which tends to age faster leading into collagen degradation that results in fine lines and decreased cell senescence. The goal of skin rejuvenation is to have healthy skin. Cosmeceuticals incorporating retinoids have been increasingly used over the past few years to promote collagen synthesis and rejuvenate the skin. Photo-induced and chronological aging processes are decelerated with retinoid application that endorses skin elasticity by free radical neutralization, new cell growth, and blood vessel promotion within the skin to help fight pigmentation and reduce fine lines. Retinoids are commercially available as creams and serums for topical application. Nanotechnology is used in the development of retinoids to counteract adverse reactions like skin irritation and purging to improve its stability, efficacy, and acceptability. Emerging studies on retinoids include formulating them within liposomes, solid lipid nanoparticles, nano-emulgels, and hydrogels. This review details understanding the aging process, the mechanism of action of retinoids to counterfeit aging, and the potential use of nanotechnological delivery in cosmeceuticals.

Pancreatic ductal adenocarcinoma carries a dismal prognosis, with high rates of metastasis and few treatment options. Hyperactivation of KRAS in almost all tumours drives RAC1 activation, conferring enhanced migratory and proliferative capacity as well as macropinocytosis. Macropinocytosis is well understood as a nutrient scavenging mechanism, but little is known about its functions in trafficking of signalling receptors. We find that CYRI-B is highly expressed in pancreatic tumours in a mouse model of KRAS and p53-driven pancreatic cancer. Deletion of Cyrib (the gene encoding CYRI-B protein) accelerates tumourigenesis, leading to enhanced ERK and JNK-induced proliferation in precancerous lesions, indicating a potential role as a buffer of RAC1 hyperactivation in early stages. However, as disease progresses, loss of CYRI-B inhibits metastasis. CYRI-B depleted tumour cells show reduced chemotactic responses to lysophosphatidic acid, a major driver of tumour spread, due to impaired macropinocytic uptake of the lysophosphatidic acid receptor 1. Overall, we implicate CYRI-B as a mediator of growth and signalling in pancreatic cancer, providing new insights into pathways controlling metastasis.

Life histories of oviparous species dictate high metabolic investment in the process of gonadal development leading to ovulation. In vertebrates, these two distinct processes are controlled by the gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH), respectively. While it was suggested that a common secretagogue, gonadotropin-releasing hormone (GnRH), oversees both functions, the generation of loss-of-function fish challenged this view. Here, we reveal that the satiety hormone cholecystokinin (CCK) is the primary regulator of this axis in zebrafish. We found that FSH cells express a CCK receptor, and our findings demonstrate that mutating this receptor results in a severe hindrance to ovarian development. Additionally, it causes a complete shutdown of both gonadotropins secretion. Using in-vivo and ex-vivo calcium imaging of gonadotrophs, we show that GnRH predominantly activates LH cells, whereas FSH cells respond to CCK stimulation, designating CCK as the bona fide FSH secretagogue. These findings indicate that the control of gametogenesis in fish was placed under different neural circuits, that are gated by CCK.

The rise of angiosperms to ecological dominance and the breakup of Gondwana during the Mesozoic marked major transitions in the evolutionary history of insect-plant interactions. To elucidate how contemporary trophic interactions were influenced by host plant shifts and palaeogeographical events, we integrated molecular data with information from the fossil record to construct a time tree for ancient phytophagous weevils of the beetle family Belidae. Our analyses indicate that crown-group Belidae originated approximately 138 Ma ago in Gondwana, associated with Pinopsida (conifer) host plants, with larvae likely developing in dead/decaying branches. Belids tracked their host plants as major plate movements occurred during Gondwana’s breakup, surviving on distant, disjunct landmasses. Some belids shifted to Angiospermae and Cycadopsida when and where conifers declined, evolving new trophic interactions, including brood-pollination mutualisms with cycads and associations with achlorophyllous parasitic angiosperms. Extant radiations of belids in the genera Rhinotia (Australian region) and Proterhinus (Hawaiian Islands) have relatively recent origins.
