Effect of Chlorpyrifos Insecticide On The Ossification of Wader Pari Fish Vertebrae (Rasbora Lateristriata Bleeker, 1854)
Authors: Ayu Dian Respati , Retnoaji Bambang - 
Published: December 2022

Due to high growth, chlorpyrifos was one of the solution to increase food production. However, this compound is dangerous because it belongs to organophosphate group which blocking the activity of acetylcholinesterase (ache) enzyme and caused nervouse failure to animal. Due to heavy rain this insecticide will run-off and contaminate the body of the river and effect the aquatic live. Wader pari was non-target animal of chlorpyrifos.Â The purpose of this study was to determine the effect of chlorpyrifos exposure on the behaviour of wader's feeding and swimming response, as well as the morphology and ossification process of the vertebrae. The study was conducted for 7 days.Â Â 4 groups of fish were exposed to chlorpyrifos with concentrations of 0, 0.001, 0.005 and 0.01 ppm. Observation of the ossification and morphological process of vertebrae is carried out using AR-Ab bone staining. Observation of waderâ€™s behaviours is carried out usingÂ descriptive analysis. It was found that the fish which exposed to chlorpyrifos showed some behavioural abnormalities in swimming and feeding response. Fish exposed to 0.005 ppm chlorpyrifos showed vertebral abnormalities which is haemal kyphosis. Kyphosis refers to Î›-shaped vertebral curvature Fragkoulis et.al, (2019). However, the ossification process that represented by Ar-Ab staining are going well.Â

Chlorella is widely used for its fast growth rate and easy cultivation with 14–30% lipid content and 36–59% dry weight. Thus, sodium hydroxide is used to increase carbon consumption, biomass, and metabolites productions in microalgae. This study was conducted to observe the effect of sodium hydroxide addition on biomass and metabolites production in photoautotrophic cultivated Chlorella sorokiniana. Microalgae C.sorokiniana (LIPI12-Al016) was obtained from the culture collection of Microalgae and Bioprocess Engineering Research Group laboratory, National Research and Innovation Agency. Then, the microalgae were cultivated in media with various concentrations of sodium hydroxide. Biomass production was measured by gravimetry, and carbon consumption was measured by acid-alkalimetry. Sodium hydroxide 60 mM gave the best growth, maximizing average carbon consumption to 691.8 mg.L-1 and biomass production to 598.3 mg.L-1. The utilization of NaOH in the medium did not increase the metabolites content, except for protein. Carbohydrate was the dominant metabolite among the others. Fatty acids profile mainly composed of C16 and C18 fatty acids, which are favorable for biodiesel production. These results gave an overview of the potency of microalgae C. sorokiniana as a CO2 mitigation agent and alternative sources of energy and nutrition.

Published: December 2022

AbstractExtraintestinal pathogenic Escherichia coli (ExPEC) is the leading pathogen in urinary tract infection. In recent years multidrug-resistant B2-ST131 E. coli clonal group has disseminated worldwide. The ST131 and its subclones H30 and H30-Rx have been identified only in a few studies from Turkey. The aim of this study is to investigate the presence of ST131 and its subclones and to analyze their adhesin virulence genes and antimicrobial resistance. A total of 250 urinary ExPEC isolates were included in the study. Resistance rates of 16 antimicrobial agents were determined by disk-diffusion. Multidrug-resistance and ESBL production were analyzed. Altogether 8 adhesin genes were investigated namely, papAH, fimH, sfa/focDE, focG, afa/draBC, iha, bmaE and gafD. A total of 39 ST131 isolate were determined and 33 (84.6%) were multidrug-resistant. ESBL production was detected in 34 (87.2%) ST131 and 61 (28.9%) of non-ST131 strains. In our study, we found a strong correlation between ST131 strains and fimH, iha, afa/draBC, papAH virulence determinants. Twenty-nine (85.3%) of 34 ST131-O25b-H30 isolates were identified as H30-Rx. All the papAH gene positive isolates were identified within ST131-O25b-H30-Rx lineage. Non-H30-Rx isolates within H30 isolates were identified as pattern 2. Almost 16% of the isolates were identified as ST131 regardless of clinical syndrome and approximately 34% of the multidrug-resistant isolates were H30-Rx subclone. We report H30-Rx as the dominant subclone of ST131 in our study. Imipenem, fosfomycin and nitrofurantoin proved to be the most effective agents according to antibiotic resistance patterns of both ST131 and non-ST131 E. coli strains.
Daily streamflow forecasting by machine learning in Tra Khuc river in Vietnam
Authors: Duy Nguyen Huu 
Published: December 2022

Precise streamflow prediction is crucial in the optimization of the distribution of water resources. This study develops the machine learning models by integrating recurrent gate unit (GRU) with bacterial foraging optimization (BFO), gray wolf optimizer (GWO), and human group optimization (HGO) to forecast the streamflow in the Tra Khuc River, Vietnam. For this purpose, the time series of daily rainfall and river flow at Son Giang station from 2000 to 2020 were employed to forecast the streamflow. The statistical indices, namely the root mean square error, the mean absolute error, and the coefficient of determination (R²), was utilized to evaluate the performance of the proposed models. The results showed that the three optimization algorithms (HGO, GWO, and BFO) effectively enhanced the performance of the GRU model.
Moreover, among the four models (GRU, GRU-HGO, GRU-GWO, and GRU-BFO), the GRU-GWO model outperformed the other models with R² = 0.883. GRU-HGO achieved R² = 0.879, and GRU-BFO achieved R²=0.878. The results of this study showed that GRU combined with optimization algorithms is a reliable modeling approach in short-term flow forecasting.

Published: December 2022

AbstractThe change in seismic activity is explored using data recorded by ocean-bottom seismometers (OBSs) and permanent seismic stations near the extinct Mid-Ocean ridge of the South China Sea (SCS) and the Manila trench. We apply the machine learning–based algorithm EQTransformer to the OBS dataset for seismic event detection and phase picking and then evaluate the precision and compare the time residuals between automatic and manual picks. We derive a catalog of earthquakes in the region and find bending-fault earthquakes in the outer rise at the northern of the Huangyan (Scarborough) Seamount chain, where no historical seismicity was reported in the routine catalog. Abundant outer-rise earthquakes occurred on both sides of the Huangyan (Scarborough) Seamounts chain, but the focal depths vary along the trench. The Wadati–Benioff zone of the eastward subducted SCS oceanic lithosphere can be clearly identified. The focal depths are down to ∼100 km near Luzon island at ∼16° N but deepen southward to a depth of ∼180 km at ∼14° N. Dips of the slab also steepen from north to south, indicating along-strike changes in the geometry of the Manila megathrust.

Türk denizciliğine önemli sayıda zabit yetiştiren Karadeniz Teknik Üniversitesi (KTÜ) Deniz Ulaştırma İşletme Mühendisliği (DUİM) Bölümü mezunlarının sektördeki konumları hakkında bir çalışma yapılmıştır. Bu çalışmada, mezunların kariyer planlamalarının öngörülebilmesi adına hipotezler oluşturulup bu hipotezlere SPSS paket programı ile analizler yapılarak cevaplararanmıştır. KTÜ mezunu gemiadamlarının mezuniyet senelerine göre açık deniz ve açık deniz haricinde istihdam edildikleri sektörler ve bu sektörlerdeki pozisyonları belirlenmiştir. Açık deniz, sektör dışı ve çalışmayanların haricinde kalan sektörler açık deniz dışı olarak adlandırılmıştır. KTÜ DUİM mezunlarının Açık denizin dışında istihdam edildikleri sektörler arasında en çok tercih edilen sektörlerin Kamu ve Denizcilik İşletmesi olduğu en az tercih edilen sektörlerin Tersanecilik ve Liman İşletmesi olduğu ortaya çıkmıştır. Tercih edilen sektörlerden Kamu sektöründe pozisyon-yeterlilik belgeleri ve pozisyon-mezuniyet senesi ile ilgili testler yapılmış ve aralarında kuvvetli ilişkiler olduğu sonucuna varılmıştır. Eğitim-Üniversite ve Denizcilik İşletmeleri sektörlerinde yeterlilik belgeleri-mezuniyet senelerinin aralarında kuvvetli ilişkiler içinde olduğu kanıtlanmıştır. KTÜ mezunu gemiadamlarının yeterlilik belgeleri ile sektörleriarasındaki ilişkilerin güçsüz olduğu Ki-kare ve Simetrik Ölçüm testleri sonucunda elde edilmiştir. Ancak açık deniz dışı sektörlerdeki gemiadamlarının genellikle uzakyol 1. zabiti ve uzakyol kaptanı yeterlilik belgelerine sahip oldukları görülmüştür. Gemiadamlarının yeterlilik belgeleri ile çalıştıkları sektörler arasındaki güçsüz ilişkiler anlamlı bir sonuç vermemektedir. Ancak gelecekte yeni mezunların sektöre girmesi ve veri sayısının artması ile oluşabilecek değişimlerden sonra daha anlamlı sonuçlar elde edilebileceği düşünülmektedir

Published: December 2022

Bhayangkari organization becomes interesting and relevant to be researched in the perspective of gender, bhayangkari is a cohesive organization, this organization consists of the wives of soldiers and wives of POLRI civil servants who are attached to the culture of the military hierarchy that is still strong. In addition, bhayangkari consists of women with heterogeneous cultural, educational and social status backgrounds. The military hierarchy system of authoritarian leadership, seniority and juniority, and personally targeting surveillance is still a culture within the Bhayangkari organization. This research methodology examines how symbolic violence occurs alive as the wife of a polri member (Bhayangkari) the subject of this study is the administrator and the member of the Bhayangkari organization is a woman, case studies this article focuses on looking at the systems and structural roles performed by Bhayangkari members. The theory of symbolic violence is applied to explain how women are controlled and victims of patriarchal oppression in this organization.
The study found that women in Bhayangkari were proud to be controlled and suppressed under the normative role of organizations with patriarchal cultures. This is reflected in the way they are active in the organization and totality in carrying out the work program. Furthermore, the special behavior was carried out to gain the prestige and pride of bhayangkari women. Finally, the study concluded that Bhayangkari women were unaware that symbolic violence practices occurred in their organizations. They don't realize that Patriarchal culture has controlled them and defined them as victims of symbolic violence. In this study is to perform data analysis techniques starting with qualitative analysis of the results of interviews, then doing an in-depth interpretation of the relationship between theory and facts that occur. Here also includes quotes (direct quotations) from informants. The issue of gender, especially in women, has become quite an important issue to study, especially looking at the number of demographic bonuses to come.

Published: December 2022

Background: Infantile hemangioma (IH) is the most common benign tumor in infancy. Most IHs resolve spontaneously and do not require treatment. Therapeutic intervention is necessary for life-threatening IH, tumors posing functional risks, ulceration, and severe anatomic distortion, especially on the face. Beta-blockers, most specifically propranolol, have been shown to induce involution of IH, which should be administered as early as possible to avoid potential complications. Purpose: To report a case of IH with visual impairment treated successfully using oral propranolol. Case: A 4-month-old girl weighing, 6.3 kg, with redness plaques on the right face since 3 weeks after birth. The lesions rapidly increased in size within 2 months, and the lesions on her right eyelid made it difficult to open her right eye. Dermatological examination showed erythematous plaques, compressible and varying in size and ptosis. The patient was diagnosed with periocular infantile hemangioma and was given oral propranolol therapy with an initiated dose 3x1 mg. The dose was increased gradually. The lesions were significantly decreased and she could open her right eye normally after 5 months of propranolol therapy. Discussion: Some cases of IH require early treatment. Early treatment is indicated for IH causing functional impairment. The use of propranolol in the management of IH is very effective in the reduction of the lesions and Has minimal side effects. Conclusion: Early diagnosis and intervention with propranolol for IH play an important role in determining the optimal outcomes.

The use of masks as self-protection from Covid-19 can cause new problems by increasing the amount of waste. Medical masks are infectious waste containing microplastics that are difficult to decompose. People’s behavior and level of knowledge may have a role in the management of medical mask waste. Therefore, this research aimed to find out the comparison of the age group <17 years and 18-25 years regarding the knowledge about the impact of medical masks on the environment as an indication of public concern for environmental preservation. The research was an analytic observational study. The sample was selected using total sampling according to age group. The variables studied were the management of medical masks and respondents’ knowledge of the impact of medical masks on the environment as measured from questionnaire data. The data obtained were tested using the independent sample t-test and the Chi-Square test. The results obtained a p-value=0.259 related to the management of medical masks and p-value=0.172 related to knowledge of the impact of medical mask waste. There was no relationship between the age group <17 years and 18-25 years related to the management of medical masks and knowledge of the impact of mask waste on the environment.
