Published: March 2024

Penelitian ini dilakukan bertujuan untuk mengetahui karakteristik tinggi gelombang di pantai Bahari Jawai Laut pada setiap musim. Perkiraan tinggi gelombang laut ditentukan berdasarkan data angin 2010-2019 dari ECMWF dan dihitung menggunakan metode SMB (Sverdrup Munk Bretscmetder). Berdasarkan hasil penelitian lapangan menunjukan bahwa pantai Bahari Jawai Laut memiliki kedalaman 1,4 m. Hasil perhitungan dibandingkan dengan data pengukuran lapangan untuk keperluan validasi dan diperoleh kesalahan relative untuk Hs dan Ts masing-masing sebesar 14,81 % dan 19,73 %. Gelombang di Pantai Bahari Jawai Laut Sambas memiliki tinggi signifikan berkisar antara 0,18–0,37 m, sedangkan periode signifikan berkisar antara 5,86-7,94 detik. Hasil pengolahan data gelombang menunjukkan bahwa Musim Barat memiliki Hs dan Ts tertinggi sebesar 0,96 m dan 17,92 detik dengan kecepatan angin 2,10–3,60 m/s. Musim Peralihan memiliki Hs dan Ts sebesar 0,31 m dan 6,08 detik dengan kecepatan angin sebesar 0,50–2,10 m/s. Musim Timur memiliki Hs dan Ts sebesar 0,37 m dan 7,42 detik dengan kecepatan angin 2,10–3,60 m/s. Musim Peralihan memiliki Hs dan Ts terendah sebesar 0,23 m dan 5,33 detik dengan kecepatan angin sebesar 0,50–2,10 m/s. Pantai Bahari Jawai Laut memiliki karakteristik gelombang laut transisi dan termasuk dalam klasifikasi gelombang gravitasi yang dibangkitkan oleh angin. Hal ini disebabkan oleh faktor angin yang berhembus dengan kecepatan yang lebih besar yang menjadi pembangkit gelombang, serta adanya pasang surut air laut. Selain itu bentuk topografi pantai menjadi penentu tinggi gelombang air laut yang terbentuk.

Sampah laut (marine debris) merupakan bahan padat yang diproduksi atau diproses secara langsung atau tidak langsung, sengaja atau tidak sengaja, dibuang atau ditinggalkan di dalam lingkungan laut. Sampah laut dapat terdampar di wilayah pantai akibat fenomena fisika di laut. Penelitian ini dilakukan pada wilayah konservasi penyu di Pantai Kampak Sungai Belacan, Kecamatan Paloh, Kalimantan Barat. Pantai Kampak yang merupakan wilayah konservasi jarang ada kegiatan manusia sehingga sampah laut yang terdampar dapat terakumulasi seiring waktu. Tujuan penelitian ini adalah untuk mendata jenis sampah yang terdampar di pesisir pantai. Terdapat tiga stasiun yang digunakan dalam penelitian ini. Pendataan sampah mengacu pada form International Coastal Cleanup (ICC) dengan luas area pendataan sepanjang 100 m tiap stasiun. Kategori sampah yang paling banyak ditemukan adalah (benda yang sering ditemukan) dengan sampah terbanyak adalah tutup botol plastik. Ada dua kategori yang ditambahkan karena tidak terdapat di form ICC yaitu macro debris dan sampah lainnya. Analisis Anova Satu Arah digunakan sebagai perbandingan pada tiap stasiun di wilayah penelitian. Hasil analisis menunjukkan bahwa banyaknya sampah yang ditemukan mempengaruhi lingkungan terutama wilayah pesisir pantai.

Published: March 2024

The increase in population in the upper Kapuas Hulu River Basin will also increase the need for land. This increase in land demand can cause land use changes, affecting the runoff coefficient. Based on the reasons above, research was conducted to determine the effect of changes in land use on the magnitude of the runoff coefficient in the upstream part of the Kapuas River Basin from 2012 to 2017 and 2017 to 2022.The runoff coefficient calculation uses the U.S. Forest Service, Hassing, Kodoatie, and Syarief methods. Each method uses different parameters to determine the results. Data processing is carried out using a Geographic Information System (GIS).The analysis and calculations show that the runoff coefficient values obtained in the Upper Kapuas River Basin using the U.S. Forest Service method in 2012, 2017, and 2022 are 0,133, 0,136, and 0,145. The Hassing method results are 0,308, 0,309, and 0,312, and the Kodoatie and Syarief method results are 0,156, 0,167, and 0,173. This value shows that the Upper Kapuas River Basin is in reasonably good condition because the runoff coefficient value is far below 1.

Published: March 2024

As part of transportation infrastructure, road infrastructure is essential in increasing community mobility and accessibility. When traffic volume increases or changes its characteristics, the intersection is the first thing that shows the inability to serve the increased traffic. Because intersections are critical points of the traffic system where vehicles from different directions meet, obstacles and traffic jams at intersections will affect the capacity of the road concerned, so the level of service at the intersection will decrease, including the speed, safety, and comfort of road users.This research aims to evaluate the performance of the third and fourth unsignaled intersections in Pontianak City (with a case study of the intersection of Jl. Sultan Abdurrahman-Jl. Sulawesi and the intersection of Jl. Alianyang-Jl. Putri Dara Nante-Jl. Putri Dara Hitam) and analyze alternatives to improve the performance of unsignalized intersections using Manual Kapasitas Jalan Indonesia and the VISSIM program application.The intersection performance analysis results for existing conditions at the third unsignaled intersection have a level of service value of A, and at the fourth unsignaled intersection, a level of service value of B. Based on the intersection performance analysis results, the intersection in its existing condition does not require any treatment or recommendations to improve its performance road infrastructure.

Authors: Darmawan Hifzhan Hanif , Mukti Elsa Tri , Kadarini S. Nurlaily
Published: March 2024

Tugu Pancasila Roundabout in Putussibau City is a 5-arm roundabout that organizes traffic in 5 directions of movement. Poor traffic management at this roundabout, such as the lack of roundabout signs and no separation island or median on roads other than the main road, makes motorists who should pass through the roundabout instead choose not to cross the roundabout and go against the flow because they want to reach their destination faster. In addition, due to the increasing population and the volume of vehicles traveling, it is anticipated that in the future, the Tugu Pancasila roundabout will have increasingly heavy traffic flows. The performance analysis of Tugu Pancasila Roundabout was calculated using MKJI 1997 and VISSIM software. The performance analysis of Tugu Pancasila Roundabout was carried out by taking roundabout geometric data, manually taking side obstacle data, and traffic volume data for three days using survey aids in the form of CCTV starting at 06.00 - 18.00 WIB. Analysis of the existing conditions in 2023, the highest degree of saturation is 0.62 with the level of service B; in the 2028 projection conditions, the highest degree of saturation is 0.73 with the level of service B; and in the 2033 projection conditions, the highest degree of saturation is 0.86 with the level of service E. With a poor level of service, the volume of vehicles and the roundabout capacity could be more balanced, so improvements are needed for the Tugu Pancasila Roundabout in Putussibau City. The improvement solution is to re-plan the roundabout following the Roundabout Planning Guidelines for Intersections (2004). For the results of the MKJI 1997 analysis of the roundabout re-planning solution, the 2028 projection obtained the highest degree of saturation of 0.54 with level of service B, and in the 2033 projection obtained the highest degree of saturation of 0.63 with level of service B. for the results of the VISSIM software simulation, the roundabout re-planning solution for the 2028 projection obtained a delay of 13.14 seconds with level of service B, and the 2033 projection obtained a delay of 15.60 seconds with level of service C.

Published: March 2024

Infections that have recently surfaced in populations whose incidence is expanding quickly or poses as a  potential threat to do so in the near future are considered emerging infectious diseases. Infectious agents that were previously unknown or unidentified may be the source of emerging illnesses. Globally, infectious illnesses pose a serious threat to both public health and the stability of economies. They have been among the top causes of death and disability for ages, posing increasing risks to human advancement and health security. The ongoing reappearance of old, neglected, and infectious disease epidemics with worldwide implications adds to the threat posed by infectious illnesses. At least thirty novel human-pathogenic infectious pathogens have evolved in the last 35 years; the majority of them being zoonotic, and research has indicated a strong correlation between the origins of these organisms and ecological, environmental, and socioeconomic factors.

Published: March 2024

Butter cookies are generally made from wheat flour as a carbohydrate source which is
high energy. Nowadays, fortified snacks are preferred because of their important nutrients.
The purpose of this research was to compare the physicochemical properties of butter
cookies with fortified knife-fish bone powder. The design of this experiment used a
completely randomized design single factor-experimental study by using four
formulations, F1 (0%), F2 (2%), F3 (4%), and F4 (6%). Data were analyzed using the One
-Way ANOVA test and Duncan’s multiple range test if they were significant. The results
showed that the butter cookies had a total energy range of 454.37 – 473.11 kcal/100 g,
carbohydrate range of 48.27 – 51.17%, protein ranged of 4.98 – 5.55%, fat content ranged
of 26.79 – 27.60%, moisture content ranged of 2.69 – 3.67%, ash content ranged of 0.76 –
3.21%, calcium content ranged of 1.85 – 2.50% and phosphorus content ranged of 0.13 –
0.33%. The recommended butter cookies by knife-fish bone added were F4 (6%) with the
highest calcium content (2.5%), the lowest moisture content (2.69%), and the lowest
calorie (454.37 kcal).

Published: March 2024

Fermented freshwater and marine products are popular in Malaysia and among these is
ikan pekasam (fermented fish). It is typically made from freshwater fish with groundroasted rice as the main source of carbohydrate during fermentation. In this study, rather
than freshwater fish, black pomfret (Parastromateus niger), a marine fish, was used to
produce ikan pekasam. Black pomfret was mixed with 3 kg of ground roasted rice and
10% (v/w of fish) water and allowed to ferment for 2 and 5 weeks at 25 – 30°C. Then,
fermented black pomfret was analysed for its physicochemical properties, compositions of
biogenic amine, urocanic acid (UCA) and organic acid, as well as sensory acceptability.
The pH and titratable acidity significantly (p ≤ 0.05) decreased and increased,
respectively, after 5 weeks of fermentation due to the increase in organic acids, mainly
lactic acid. Histamine, putrescine, cadaverine and 2-phenylethylamine increased rapidly
after 5 weeks of fermentation but histamine was within the recommended level (50 mg/kg;
US Food and Drug Administration (USFDA)). The strong correlation between trans- and
cis-urocanic acid indicated that photoisomerization of trans-UCA into cis-UCA occurred.
Overall, principal component analysis (PCA) revealed that the two-week fermented black
pomfret was more acceptable to the consumer panellists than the five-week due to its
acceptable aroma, saltiness, sourness and texture. Notably, this two-week sample had
significantly (p ≤ 0.05) lower biogenic amine and UCA contents; suggesting a safer and
good quality of ikan pekasam.

Synbiotic yogurt products can be developed using mangrove apple extract inulin as a
prebiotic in combination with Lactobacillus plantarum to form a probiotic. Therefore, this
study aimed to determine the optimal concentrations of inulin extracted from mangrove
apple for the viability of L. plantarum as a synbiotic in vitro and its antibacterial activity
against Staphylococcus aureus. The samples were divided into 5 groups and 4 replicates
consisting of different concentrations of inulin extracted from mangrove apple (IEMA) at
0, 3, 6, 9, and 12% w/v, which was combined with L. plantarum as a synbiotic. The result
showed that the addition of IEMA with different concentrations had a significant effect
(p<0.05) on the viability of L. plantarum in gastric juice and bile salt after 5 h of
exposure. The total bacteria significantly decreased (p<0.05) after 4 weeks of storage
period. The antibacterial activity of IEMA at concentrations of 9% and 12% was higher
than other treatments as demonstrated by p<0.05. IEMA increased the viability with the
concentration of 9% being the most effective (p<0.05) on acid, bile salt, resistance, and
storage periods. Based on the results, IEMA can also inhibit the growth of S. aureus.

THE ATTITUDE OF DIFFERENT CURRENTS AND MADHHABS OF ISLAM TO THE CONSUMPTION OF SEAFOOD
Authors: Maevskaya Lyudmila , Khaisam Aga
Published: March 2024

The relevance of this study is due to the fact that scientific papers have not actually considered the features and rules related to the use of seafood according to the religious rules of Islam. It is generally believed that Muslims do not eat blood, pig meat, dead meat and alcohol. In fact, this is true, but it should be noted that certain trends and law schools have their own nuances related to the consumption of seafood. Ignorance of these issues can complicate the export of certain goods to some Muslim countries, as well as to banal misunderstandings when communicating with Muslims by representatives of certain movements and schools. The subject of the study is the rules of some currents and madhhabs related to the consumption of seafood. The purpose is to clarify issues related to the use of seafood in Islam. The main method is hermeneutical, which includes the study of the Koran, the sayings of the prophet and the works of Islamic theologians related to the consumption of seafood. As a result, it was found that representatives of the Hanafi Madhhab and the Shiite movement consider some seafood forbidden for consumption. The results of the study can be applied in the development of Halal standards and certification of certain types of products. Also, the results of this article may be useful in the preparation and teaching of religious studies courses. Islamic theology and selected trade and economic disciplines.Key words: Islam, Halal, Haram, madhhab, Hanafi Madhhab, Shiism, seafood.

Published: March 2024

This article examines the bioclimatic potential (BCP) (according to S.A. Sapozhnikova) and agroclimatic characteristics of the Central Chernozem Region, including the Oryol oblast, with spatiotemporal trends of their variability analyzed from 1980 to 2021. In the early 2000s, compared to the late 20th century, there was a 10% increase in the BCP, a 13% rise in the sum of active temperatures, and a 6% longer active growing season. Furthermore, shifts in the isolines of the sum of active temperatures and the hydrothermal coefficient (HTC) occurred. The active temperature isotherm of 3000°C moved northward, and it is now running through the Belgorod and Voronezh oblast. As a result of the observed hydrothermal conditions, a significant part of the Central Chernozem transitioned from the zone with sufficient moisture (1.3 ≥ HTC > 1) to an arid zone (1 ≥ HTC > 0.7). The overall growth of the BCP in the Central Chernozem Region can be associated with a considerable rise in the sum of active temperatures and a reduction in moisture supply.

Published: March 2024

The paleosol profiles of the Urzhumian from the section on the right bank of the Volga River near the village of Grebeni were studied by field and laboratory methods. Two paleosol profiles on red clayey siltstones were identified. They were classified as strongly developed Vertic Calcisols based on their pedogenic features such as horizonation, carbonate nodules, slickensides, etc. The climate during their formation was found to be seasonally wet and warm. The mean annual precipitation was calculated from the geochemical indices of the paleosols and amounted to 522 mm/year for the Late Urzhumian. The reddish-brown soils in the dry subtropics of the Mediterranean or Australia can be considered as modern analogs of these paleosols.

The upper paleosol profile is a pedocomplex consisting of four single soils separated by nonpedogenic carbonate layers in the middle part. The pedocomplex structure contains one lacustrinepalustrine and two lacustrine-playa sedimentary microrhytms, which indicate the setting of lacustrinealluvial plains and make it possible to estimate the duration of its formation spanning thousands to tens of thousands of years.

A pedocomplex with a similar structure was identified in the upper part of the Urzhumian of the reference section in the Cheremushka Ravine. Both pedocomplexes have very similar mineralogical, chemical, and granulometric composition of their siliciclastics, as well as the isotopic composition of pedogenic nodules. The biostratigraphic position of the pedocomplex in the Cheremushka Ravine shows that it is coeval with the pedocomplex of the Grebeni section. The correlation between them is direct, making them a useful pedostratigraphic marker. It is suggested to label this marker horizon as the “Crimson Clay pedocomplex”.
The Temperature Factor in Selecting the Areas of Subaqueous Discharge of Near-Surface Water
Authors: Tatarkin A. V. , Krasilnikov P. A.
Published: March 2024

This article considers the theoretical grounds for advancing the existing aquatic research techniques, including a complex of thermometry and resistivimetry methods. The transient processes that influence the temperature change in the “water–air” system were explored. The need to take into account the thermal characteristics of all elements involved was highlighted. Using the theory of heat exchange and the idea that the water source can be distinguished from the general temperature field, a formula for measuring the general temperature field was derived. It was found that the areas of subaqueous discharge of near-surface water can be localized by the temperature difference between the watercourses and the water source. The multivariate analysis based on the absolute value and sign of the difference temperature parameter was used to determine the salinity value and the changes of the salinity type with depth. The criteria obtained during the theoretical studies were successfully tested and verified on a watercourse located within the industrial agglomeration of the Perm region, which indicates their high potential for solving practical hydrogeological problems.
Halotolerant Benzoic Acid-Degrading Bacteria of the Genus Dietzia

Published: March 2024

Six benzoic acid-degrading bacteria of the genus Dietzia were isolated from the saline ecotopes of the Verkhnekamskoe and Yakshinskoe salt deposits (Perm region, Komi Republic, Russia). Benzoic acid (BA) may accumulate in ecosystems through technogenic processes, as well as during the microbiological decomposition of complex organic compounds containing an aromatic ring. The strains studied here were found to be closely related to D. psychralcaliphila, D. kunjamensis subsp. kunjamensis, D. cercidiphylli, and D. maris. It was shown that they are halotolerant and able to thrive on BA as their sole carbon and energy source in the absence of salt or in the presence of 50–70 g/L NaCl. They also contain benA genes encoding the α-subunit of benzoate 1,2-dioxygenase, the key enzyme of BA degradation. The highest level of similarity (79.32–91.38%) was observed between the nucleotide sequences of the benA genes of the strains considered and the homologous sequences of Actinomycetes representatives from genera such as Dietzia, Mycolicibacterium, Geodermatophilus, Pseudonocardia, Corynebacterium, and Raineyella. The described active BA degraders belonging to the genus Dietzia have the potential to aid in the development of bioremediation techniques for environmental objects contaminated with mono(poly)aromatic pollutants and subject to salting.

This study explores the combined toxic effect of Mn(II) and resorcinol (0.01 n and 0.2 n) on duckweed (Lemna minor). During the acute experiments, the plants released electrolytes into the aquatic environment after 30 min of exposure to the toxicants, indicating a disruption of tissue permeability as a test response. The experiments showed that the toxicity of the equinormal mixtures of resorcinol and Mn(II) (0.2 n each) increased relative to their single solutions. This was observed both in the freshly prepared solutions and in the solutions stored for 20 h prior to the experiments. The change in the UV absorption spectra indicates that there was complexation or other interaction between resorcinol and Mn(II) at equinormal concentrations (0.01 n). At the Mn(II) : resorcinol ratio of 1:20 (0.01 n Mn(II) and 0.2 n resorcinol), the toxicity of the system to duckweed decreased compared to the separate effects of these substances. The results obtained highlight the importance of considering the interactions between heavy metals and phenolic compounds when assessing the quality of aquatic environments.

Chronic Obstructive Pulmonary Disease (COPD) is associated with increased health complications, leading to a rise in mortality rates. COPD remains a significant global health issue, underscoring the importance of recognizing symptoms, facilitating diagnosis, and implementing effective treatment strategies. However, information on lifestyle risk factors and the management of COPD remains fragmented. This review paper aims to understand the clinical pathophysiologic changes triggered by lifestyle practices and their management strategies. It is important to understand its symptoms, diagnostics criteria, and treatment to correlate with lifestyle risk factors and to identify effective lifestyle interventions. Lifestyle practices as defined by dietary practices such being anorexia and low fruit and vegetable intake, smoking habits, alcohol consumption, and physical inactivity have increased the risk of COPD. This review suggested lifestyle approaches for COPD treatment such as regular exercise, a healthy diet, and avoiding smoking. In this case, the development of the guided improved intervention is important for a better understanding of the mechanisms between COPD and its associated lifestyle practices. This information may help clinicians, health practitioners, and dietitians to guide patients to implement improved dietary interventions. To avoid the progression of COPD, lifestyle practice therapy could be the most effective strategies that aid with medications as prescribed by the physicians.

Published: March 2024

Constipation is one of the most common symptoms in childhood. Sodium-phosphate enemas are frequently preferred for the treatment of constipation and bowel cleansing. We present a case of a 5-year-old boy who presented to the Pediatric Emergency Department with complaints of constipation, abdominal pain, abdominal distension and vomiting; had been constipated for about two years and had poor nutrition, and received a full dose of CT enema® twice in the last 12 hours before admission to the hospital. Upon arrival at the Pediatric Emergency Department, the patient was given a pediatric fleet enema because he had dense stools according to radiographic evidence. Poisoning due to Sodium-phosphate enema was considered due to severe hyperphosphatemia and hypocalcemia in the laboratory evaluation. Rapid intravenous hydration and 1 mL/kg calcium gluconate intravenous infusion were started. Electrolytes returned to the normal range at the 14th hour of follow-up without the need for additional treatment. This case is presented to emphasize that due to the widespread use of sodium-phosphate enemas in the treatment of chronic constipation, these enemas can cause phosphate poisoning even when used in healthy patients at therapeutic doses.

Published: March 2024

Background/Aim: This study examines patients diagnosed with vitamin B12 deficiency in our department. Although rare, vitamin B12 deficiency is one of the causes of megaloblastic anemia, which can lead to negative outcomes in patients. We aim to promote earlier diagnosis to protect patients from these negative effects. Therefore, this study will contribute to raising awareness in the literature.
Methods: Retrospectively, we included a total of 127 outpatient children, aged 0–18 years (0–215 months), who were diagnosed and treated for vitamin B12 deficiency at the Bagcilar Training and Research Hospital Child Health and Disease Clinic between October 2014 and February 2015.
Results: Among the patients, 67 (53%) with vitamin B12 deficiency were female, while 60 (47%) were male, indicating a higher occurrence in girls. Vitamin B12 deficiency was most commonly observed in the age groups of 0-2 years and 12-17 years (adolescents). The mean vitamin B12 level was 168.1 (34.1) pg/mL, the mean hemoglobin level was 12 (1.9) g/dL, and the mean MCV (mean corpuscular volume) was 78.4 (8.1) fl. Anemia was observed in 38% of the patients, bicytopenia in 4%, neutropenia in 6%, thrombocytopenia in 9%, pancytopenia in 3%, and macrocytosis in 2%. Non-iron-deficient patients showed no difference in mean hemoglobin and RDW (red cell distribution width) when compared to iron-deficient patients. However, their B12 levels were lower. The prevalence of iron deficiency did not differ between girls and boys. Comparing patients with vitamin B12 levels lower than 150 pg/mL to those with higher levels, there were no significant differences in average Hb, MCV, and RDW.
Conclusion: It should be noted that macrocytic anemia is not exclusive to vitamin B12 deficiency. Vitamin B12 deficiency can manifest as normocytic anemia and should not be overlooked in biochemical assessments. It is recommended to conduct nationwide and regional prevalence studies to evaluate vitamin B12 deficiency as a public health issue and to develop new solutions accordingly.

Firma-se este presente trabalho em uma perspectiva de leituraque enfatiza um centramento na questão do tanático como fator que irádeflagrar em Morte e Vida Severina, poema dramático do escritorpernambucano João Cabral de Melo Neto, as possibilidades existenciaisque solidificam a disposição do ser-no-mundo como constante devenir ecomo elemento sintetizador tanto de um não-ser que lhe é intrínseco,quanto da idéia de negação da negação absoluta representada pela morte, posto que na própria descontinuidade de seu estar-lançado encontra estímulo para ir em busca de um ainda-não-ser que se lhe abre como um horizonte pleno de um poder-ser. A hermenêutica ontológica do filósofo alemão Martin Heidegger irá se associar aqui, respeitando-se asinevitáveis divergências de óptica conceptual, ao conceito de utopia a quese empenharam em estudar pensadores como Emst Bloch e KarlMannheim, entre outros. DOI: 10.28998/0103-6858.2003v2n32p135-151

La cité des dames: utopia e gênero
Authors: Calado Luciana Eleonora de F.
Published: March 2024

Caracterizada como um período de intensa repressão feminina, aIdade Média representa também uma época de contestações, em particularna vida literária, seja com a expansão do gênero poético conhecido como"Cantiga de Amigo" (Chanson de Femme, Frauenlied), que consiste naexpressão dos sentimentos através de um eu-lírico feminino, seja com aprópria produção de mulheres, as chamadas trobairitz. Dentre estas, aescritora do século XIV Christine de Pizan é o nome mais notável, menospela sua vasta e variada produção poética e prosaica, mas especialmentepela ousadia em deslocar o papel da mulher nos escritos da época - na suagrande maioria, misóginos - em sentido de uma abordagem feministaquestionadora da "natural" superioridade masculina. Neste artigo, pretende-seanalisar uma das mais importantes obras de Christine de Pizan, La Citédes Dames (A cidade das damas), enfocando a imagem do feminino e oplano utópico desta "cidade metafórica". DOI: 10.28998/0103-6858.2003v2n32p17-28
