Abstract

Extended-spectrum beta lactamase producing Escherichia coli (ESBL-Ec) colonization in poultry worker is one prominent of zoonotic problem, in which of it, daily contact, working period and biosecurity play role. This study aimed to identify association between daily contact, working period and biosecurity to ESBL-Ec’ colonization. Rectal swab was applied to poultry workers to identify phenotypic ESBL-Ec. Duration of contact, working period and biosecurity parameter data was obtained through structured questionnaire. A number of 51 poultry workers with a mean age of 42.7 years, and 54.9% are male. Nineteen poultry workers (37.3%) was tested positive for ESBL-Ec. Daily contact of ≥ 2 hours is not significant (p = 0.291; 95% CI) while working period of ≥ 3 years is significant (p = 0.024; 95% CI) to ESBL-Ec’ colonization. Twenty-one biosecurity parameters were measured, with 3 parameters significant association: sick chicken isolation (p = 0.022), existence of quarantine shed (p = 0.018) and past biosecurity training (p = 0.047). In conclusion, working period ≥ 3 years, sick chicken isolation, existence of quarantine shed and past biosecurity training is associated with ESBL-Ec’ colonization to farmer.

Abstract

In this research, SVM will be used to differentiate between plain nail art designs (class 0), 3D nail art designs (class 1), and hand painting nail art designs (class 2). The dataset used consists of images of nail designs that have been collected and analyzed previously. First, the dataset is divided into three different classes based on the type of nail design. The first class (class 0) includes plain nail art designs, then the second class (class 1) is 3D nail art designs, and the third class (class 2) is hand painting nail art designs. This process is carried out to allow SVM to learn the feature differences between the two types of designs. The data used will be divided into training and testing data and divided into three data division schemes, namely 60/40, 70/30, and 80/20. Based on the results of the research discussed, it can be concluded that classification using the Linear SVM model on three data sharing schemes provides the best level of accuracy on the 80/20 scheme, namely 81.25%. Meanwhile, classification using the non-linear SVM model achieved the highest level of accuracy of 95% in the 80/20 scheme with the RBF Kernel. Thus, the SVM model that is suitable for classifying nail art designs is a non-linear SVM model with the 80/20 scheme. The accuracy results obtained from this research also show that SVM provides good performance in classifying nail art designs.

Using the ADDIE model which includes the stages of analysis, design, development, implementation, and evaluation. The subjects of the study were students and teachers of grade IV of SD Negeri 02 Sidorejo. Data collection was carried out through test and non-test techniques with data analysis in the form of product analysis. The results of the expert validator's assessment were very feasible to obtain a percentage of 87%, while the media expert gave a percentage of 93%. The data is normally distributed with values The data is normally distributed, with values of 0.54 and 0.98 significance on the small-scale pretest and posttest and for a large scale of 0.31 and 0.10. The results of the t-test with significance (α) below 0.05 are 0.008 and 0.000. In the average increase test, the N-gain value was obtained at 0.67 on a large scale so that the effectiveness value was in the medium category. On a small scale, the mean value was 0.65, which was in the medium category. The conclusion of this study is that it is very feasible and improves learning outcomes. It is recommended that interactive PPT media based on audiovisual with the PBL model can be used by teachers as a learning medium so that learning objectives are achieved.

Abstract

The goal of 21 st century learning is to develop 4C skills in students. Problem solving is one part of the 4C skills that needs to be improved. Problem solving skills can be integrated to solve problems in the real world. In fact the level of problem solving skills of students at SMAN 3 Panyabungan is still relatively low. One solution that can be done to solve these problems is by using a socioscientific issue approach. The goal of this research is to  specify the significant influence of the socioscientific issue approach on the problem solving skills of class X phase E students. This categorize of research is experimental research using a posttest only design and the sampling techniquei used was cluster random sampling. The population in this study was all class X phase E while, the sample was class X phase E1 as the experimentali class and class X phase E7 as the control class. Results obtained, the average value of the experimental class was higher than the control class, so that the value of th = 3.945 and the value of tt = 2.017 were obtained with a significance level of 0.05.

Abstract

Kamal Beach in the Madura Strait is suspected to have experienced heavy metal contamination due to ship recycling industry activities. Heavy metals have a negative impact on the aquatic environment, aquatic biota and even humans. This study aims to analyze the impact of heavy metal content in Kamal Beach, especially heavy metals Fe, Zn, and Cu as heavy metals found in the region on the histopathological aspects of the gill and liver organs of aquatic biota, namely mullet fish (Crenimugil seheli). The levels of heavy metals Fe, Zn, and Cu were analyzed using the AAS (Atomic Absorption Spectometry) method in accordance with SNI 6989.4:2009. Hiatopathological analysis of the gill and liver organs was carried out using the scoring method where from the results of the analysis it was known that the damage that occurred in the gill organs was in the form of edema, hyperplasia, lamellar fusion, and necrosis while damage to the liver organs included degeneration, necrosis, and congestion. Damage to the gill and liver organs of mullet fish is caused by the high content of Zn and Cu in water and sediment.

Abstract

The purpose of this review is to determine the sugar content profile in various types of honey produced by Apis mellifera, such as monofloral, unifloral, extra-floral, and honeydew. Generally, the goal is to assess the average sugar content parameters within acceptable ranges set by SNI, Codex, and EU as quality and sugar content requirements. Among the honey types studied, monofloral honey met the sugar standards but some samples were found to have low sugar content, ranging from 21.77% to 58.95%, below SNI and Codex standards. In contrast, unifloral, extra-floral, and honeydew honeys exhibited higher sugar levels, in accordance with established standards, ranging from 73.40% to 83.9%. The differences in sugar content among the types of honey produced by A. mellifera are influenced by nectar sources, geography, climate, and vegetation. Monofloral honey tends to have lower sugar content, while unifloral, extra-floral, and honeydew honeys are richer in sugar, making them more compliant with honey quality standards. Further research should focus on identifying plant species and the quantity of nectar that can consistently produce honey with sugar content meeting established quality standards.

Abstract

Haliclona sp. is a genus of demosponges in the family Chalinidae. Demospongiae are a type of sponge that lives in marine environments and is known for its unique, often branching skeletal structure. The use of antibiotics has led to the selection of pathogenic microorganisms in humans that are more resistant to many types of drugs, resulting in poorer treatment outcomes in cases of infection. Bacteria can become resistant to antibiotics due to improper dosing, inaccurate diagnosis, and inappropriate use of antibiotics against the causative bacteria. This study aims to determine the antimicrobial activity of the methanol extract of Haliclona sp. as an inhibitor of pathogenic microbes. This research employs a descriptive method with antagonistic testing. The results of the methanol extraction process of the symbiotic bacteria in Haliclona sp. produced a thick, dark brown extract. The results of the antagonistic test showed that the clear zones formed on the three test microbes were categorized as strong.
