Authors: Helminasari Shorea , Gering Septiani Long , Salsabila Amalia
Published: September 2024

Kerusuhan Mei 1998 berujung pada keberhasilan mahasiswa menggulingkan kekuasaan Presiden Soeharto yang menjadi klimaks dari rasa ketidakpuasan masyarakat akan Orde Baru. Semenjak berakhirnya rezim Orde Baru pada tahun 1998, Indonesia memasuki babak aktual sebagai suatu negara. Reformasi seakan menjadi titik balik yang merubah total seluruh aspek kehidupan Indonesia di berbagai bidang terutama pada sistem politik, pemerataan sistem politik, kesejahteraan ekonomi dan pembangunan nasional, pengoptimalisasi fungsi partai politik sebagai sarana komunikasi politik, sosialisasi politik, rekrutmen politik, artikulasi kepentingan, dan sarana agregasi kepentingan. Namun berangkat dari hal-hal tersebut, terdapat beberapa pihak yang masih mempertanyakan apakah yang kita sebut sebagai Reformasi itu benar-benar dapat menghantarkan Indonesia pada negara yang demokratis, kemudian apakah Indonesia sudah menjadi sebuah negara yang berdemokrat dimana seluruh rakyatnya merasakan keadilan yang menyeluruh, serta poin terpentingnya apakah reformasi telah membawa perubahann yang baik bagi bangsa Indonesia. Hal itulah yang akan menjadi fokus utama hadirnya kajian ilmiah ini, sebab masih begitu banyak hal-hal yang belum terselesaikan dan ditemui jawabannya. Melalui studi literatur dari buku-buku, artikel, maupun jurnal terdahulu, kajian ilmiah ini akan menjawab sederet pertanyaan-pertanyaan tersebut.

Published: September 2024

Membina keamanan maritim tidak hanya berfokus pada penguatan daya tembak melalui akuisisi alat utama sistem senjata (alutsista), tetapi juga berfokus pada faktor pendukung operasi laut, seperti pangkalan Tentara Nasional Indonesia Angkatan Laut (TNI AL), hal ini tentunya juga perlu diperhatikan. Pangkalan TNI AL memainkan peran penting dalam mendukung operasi sehari-hari yang dilakukan oleh personal TNI AL. Pembangunan dan penggelaran kekuatan pada pangkalan TNI AL harus memperhatikan dan memprioritaskan daerah rawan keamanan, daerah perbatasan, daerah rawan konflik dan pulau-pulau terpencil sesuai dengan kondisi geografis dan strategi pertahanan. Dengan merelokasi pangkalan TNI AL dekat dengan daerah operasi atau daerah yang rentan terhadap ancaman, maka dapat mengurangi waktu tanggap, menghemat biaya operasional, meningkatkan jangkauan operasional, meminimalisir potensi ancaman dan menjadi alternatif untuk mengatasi keterbatasan anggaran. Adapun metode penulisan jurnal ini menggunakan pendekatan deskriptif kualitatif, dengan menghasil data bahwa penataan kedaulatan maritim tidak hanya berfokus pada penguatan daya tempur melalui penambahan dan pembaruan alutsista sjaa, namun juga pada faktor daya dukung terhadap sebuah operasi laut, seperti Pangkalan Utama TNI AL. Maka guna mendapatkan keamanan maritim Indonesia yang kuat, perlu ada peningkatan dari segi kebijakan pemerintah, kekuatan Angkatan Laut dan kekuatan unsur – unsur keamanan laut.

The present study explores the micromagnetic properties of ultrathin elliptical nanorings with whirling magnetic structures called skyrmions. The simulations investigate the creation and dynamics of skyrmion using the Object Oriented MicroMagnetic Framework (OOMMF). A cobalt nanoring placed on a platinum substrate makes up the model system. To closely resemble genuine materials, material properties including saturation magnetization, Dzyaloshinskii-Moriya interaction (DMI) constant, and Heisenberg exchange stiffness are carefully selected. The simulations methodically examine the effects of applied magnetic fields and different DMI strengths. In order to comprehend their influence on the stability and deformation of the skyrmions inside the nanoring, these external elements are investigated. Our results show a strong relationship between the generated skyrmion size and shape and the DMI strength. Distinct stability and deformation patterns result from varying DMI intensities, underscoring the pivotal function of this interaction in controlling skyrmion behavior inside the nanoring geometry. At higher DMI values, skyrmions exhibit irregular patterns and increased magnetic torque, with variations in domain wall thickness and skyrmion configuration over time. We demonstrate that by optimizing the combination of DMI strength and magnetic field, controlled generation and stabilization of skyrmions in nanostructures can be achieved. This work widens the opportunities for future developments in spintronic technology by aiding in the creation of nanoscale memory and information devices.

This work used a twofold method to investigate the effects of manganese (Mn) doping on zinc oxide (ZnO) nanoparticles. Density Functional Theory (DFT)-based theoretical computations and experimental characterisation are combined in this study. The first emphasis is on the analysis of experimental data from ZnO nanoparticles doped with Mn that were generated by a straightforward co-precipitation process. The purpose of this analysis is to disclose the impact of Mn doping in relation to pure ZnO nanoparticles. DFT calculations are used to offer a theoretical basis for the observed behavior, complementing the experimental results. The study employs typical DFT methods for energy convergence, structural optimization, band-gap computations and Density of States (DoS) analysis. The purpose of these calculations is to clarify the structural and electrical characteristics of ZnO's wurtzite crystal structure. The study includes a Hubbard-U adjustment in recognition of the widely acknowledged underestimating of bandgap values by standard DFT. The bandgap predictions for the Mn-doped ZnO nanoparticles are improved with the help of this adjustment.The samples prepared where characterised for its morphological, optical, structural and dielectric analysis. The X-ray diffraction data confirmed hexagonal wurtzite structure. The SEM and EDAX were used to confirm composition and morphology and hexagonal disc-like structures were observed. The PL showed intense green and faint blue emissions. The dielectric studies were performed, and Mn-doping showed clear influence in results.

Semiconducting metal oxides have piqued researchers' attention in the realm of energy conversion due to their importance in primary research and future applications. The current study focused on the synthesis, preparation, and optimization of the physical and electrical properties of the direct and reverse ratios of the precursors (Zinc Acetate and Tin (II) Chloride) used to prepare ZTO substrates at two different deposition temperatures using spray pyrolysis technique. Zinc acetate is kept constant in the first set, whereas tin chloride is kept constant in the second set, and other components are altered from 0.05M to 0.25 in 0.05-step increments. The XRD study reveals that all spray-deposited ZTO thin films are polycrystalline in nature, with a preferred orientation along the (101) plane. From morphology studies observed that while the deposition temperature increased, smooth and uniform morphology is achieved. Optical studies show that the percentage of transmittance decreased while the deposition temperature increased. Hall Effect studies show that after changing the molar concentration as well as the deposition temperature there is change in conductivity and mobility values. Except for lower ratio films, the transmission percentage of ZTO films recorded in the visible area approaches 80%. The 3D laser profilometer results show that varying the starting materials' molarity (>Ra&Rz) and deposition temperature (<Ra&Rz) leads to changes in surface roughness and improved film growth.

Vanadium-assisted cobalt ferrite nanoparticles generated using the co-precipitation process have better structural, morphological, and electrochemical properties than pure cobalt ferrite. The remarkable crystallinity of the cubic crystal structure was confirmed by X-ray diffraction (XRD) investigation. The use of field emission scanning electron microscopy (FESEM) demonstrated the presence of vanadium and consistent elemental composition with cobalt ferrite, while energy dispersive X-ray analysis (EDAX) verified the spherical nanoparticles with an average size of around 20 nm. Electrochemical impedance spectroscopy (EIS) indicated significant improvements in electrochemical performance, with a reduction in equivalent series resistance (ESR) from 1.54 Ω to 1.22 Ω and charge transfer resistance from 1.68 x 10⁻³ Ω to 1.5 x 10⁻³ Ω for V-doped CoFe₂O₄. Additionally, lower internal and Warburg resistance values were observed for V-doped CoFe₂O₄, suggesting efficient ion transport and storage capabilities. These findings highlight the potential of vanadium-doped cobalt ferrite nanostructures as promising materials for next-generation supercapacitors, addressing critical challenges in energy storage for renewable energy systems and portable electronics. Future studies should concentrate on refining the synthesis procedure and investigating other dopants in order to significantly improve the efficiency of supercapacitors based on cobalt ferrite.

Published: September 2024

Urinary tract infections (UTIs) are the leading cause of maternal morbidity and poor birth outcomes. Pregnancy changes increase UTI risk. A larger bladder, less tone, and a shift in vaginal flora are changes. Eradicating pathogens in the urogenital tract can lower the risk of infection-related preterm labor by stopping the progression of asymptomatic bacteriuria into a more serious infection. Objective: To determine the association of preterm labor with urinary tract infection and the preventive role of ceftriaxone. Methods: A case-control study was conducted at the Department of Obstetrics and Gynecology, Khyber Teaching Hospital, Peshawar, from 14 December 2021 to 10 June 2022. 130 pregnant women who met the selection criteria were recruited from the hospital's post-delivery wards. The participants were then separated into a case group and a control group. Protocols for treating UTIs in female were followed. Ceftriaxone was administered to the group of participants who were UTI-positive. Results: The mean age of female in the case group was 28.88 ± 7.18 and in the controls group was 28.97 ± 6.85 years. The mean gestational age at delivery in cases was 34.28 ± 1.34 weeks and in controls 39.4 ± 1.11 weeks. There was a significant association between preterm labor and urinary tract infection (p= <0.05). Administration of ceftriaxone reduced the risk of preterm labor (p=0.001). Conclusions: It was concluded that there is a significant correlation between UTIs and premature labor and ceftriaxone plays an important role in reducing preterm delivery of UTI patients.

Authors: Ihotu Otokpa Emmanuel , Etim Etim Esin
Published: September 2024

This study explored enhancing the nutritional value and functional properties of carbohydrate-rich diets by incorporating soybeans into millet, cassava, and yam. Soybeans, known for their high protein, unsaturated fats, and micronutrients, were used to fortify these staple foods. Proximate analysis assessed the macronutrient content of both the original and soybean-enriched samples, while functional properties such as water and oil absorption capacities, swelling index, bulk density, and gelation capacity were evaluated. Results showed significant increases in protein content, particularly in the millet-soybean mixture (29.81%), with relatively low levels of fat and ash. Functional assessments indicated millet’s highest gelation capacity and cassava’s superior water absorption. These findings suggest that soybean fortification can improve carbohydrate-rich diets’ nutritional quality and versatility. Further research is recommended to assess the impact of these dietary modifications on human health and consumer acceptance.

A total of 20 seronegative heifers against 4 BRD viruses, Bovine alphaherpisvirus-1 (BoAHV-1), Bovine viral diarrhea virus (BVDV BVDV-1: Pesti virus A; BVDV-2: Pesti virus B), bovine respiratory syncytial virus (BRSV) and Bovine parainfluenza virus-3 (BPIV3) were chosen for this study. The heifers were divided into three groups. The first group (n=6) received no vaccination and was kept as a control. The second and third groups (7 heifers each) were vaccinated twice with either a modified live (MLV) or inactivated vaccine. The gene expression level of interleukin-6 (IL-6) and interferon-gamma (INF-γ) was measured using real-time quantitative PCR (RT-qPCR) on the 7th, 14th, 21st, 28th, and 60th days post-vaccination. The results were compared with the control group to study the effectiveness of the vaccines.
Results:
There was an upregulation in the expression level of IL-6 and INF-γ in both MLV and inactivated vaccinated groups. The level of IL-6 mRNA expression was statistically increased from the 14th and 28th days post-vaccination in MLV and inactivated vaccine groups, respectively. The expression level of INF-γ increased significantly from the 2nd and 4th weeks post-vaccination in the MLV and inactivated vaccine groups, respectively. The mean expression level of IL-6 and INF-γ mRNAs was significantly higher in the MLV vaccine group than in the inactivated vaccine group at each examination time.
Conclusion:
Both investigated vaccines are efficient in stimulating CMI, particularly with the MLV vaccine showing a higher preponderance in IL-6 and INF-γ.

Authors: Ahmed Ahmed , Hassan Muntaha
Published: September 2024

Background:
Milk and its products are very sensitive to spoilage if they are kept under unsuitable conditions which may provide favorable circumstances for the growth of specific spoilage organisms, Pseudomonas fluorescens accounted as the most dominant indicator for milk spoilage.
Aim:
This study highlights to monitor the prevalence of P. fluorescens as a spoilage indicator organism in cow raw milk and its contact surfaces represented by teat surfaces and milk tanks in Nineveh province.
Methods:
A total of 150 samples from cows' raw milk, teat surfaces and milk tank swabs were collected from different locations of Nineveh province from October 2023 till February 2024.The P. fluorescens was detected by using conventional cultivation methods supported by molecular detection of the target pathogen using polymerase chain reaction technique.
Results:
Out of 150 samples 48(32%) were positive for the prevalence of P. fluorescens by traditional methods and 39(26%) were positive using PCR assay according to the 16SPflu gene yielded a band at 850 bp. The P. fluorescens was recovered at 19(38%) from raw milk. Teat surfaces revealed a higher isolation rate 11(22%) compared to milk tanks 9(18%). The mean counts of Pseudomonas in cows raw milk revealed 4.38, 6.29 and 7.37 log CFU/ml for the zero, three and six days of storage in chilling temperature. Results of DNA sequencing of the 16SrRNA gene revealed 12 strains recorded in the GenBank nucleotide sequence database.
Conclusion:
Our results shed light on the risk of P. fluorescens prevalence as spoilage indicator in raw milk and surrounded surfaces which inevitable to apply the hygienic procedures during milk collecting, processing and preservation to increase the shelf life of the products and ensure milk safety and consumer health.

Background:
Tick is one of the most important ectoparasites which distributed worldwide and plays an obvious role in transmission of different infections to humans and animals as dogs.
Aim:
This study conducted to molecular demonstration of B. gibsoni in ticks of stray dogs and phylogenetic analysis of study isolates to detect their identity to global isolates. Prevalence of ticks in dogs, identification of tick species, and its relationship to some risk factors was aimed, also.
Methods:
A total of 97 stray dogs were inspected grossly to detect and collect of ticks existed in different body parts. After collection, all ticks were examined morphologically to identify its species, and then molecularly by the polymerase chain reaction (PCR) assay to detect B. gibsoni in different species of ticks. Local B. gibsoni isolates were sequenced, documented in the NCBI database, analyzed phylogenetically and compared with the global GenBank-NCBI isolates.
Results:
In the current study, ticks were detected in 43.3% dogs, and showed to be varied in number and distribution among different body parts of each dog. Concerning its distribution, ticks were observed significantly on abdomen, ear, and perineal region. Relation to risk factors, ticks were increased significantly in dogs of 6 months old in comparison to older dogs, males more than females; and in rural areas more than dogs of sub-urban and urban areas. Based on morphology, different tick species were seen including Hylaomma anatolicum (86.12%), Rhipicephalus sanguineus (11.99%) and Rhipicephalus turanicus (1.89%). Targeting 18S rRNA gene, PCR assay reported 3.79% positive ticks to B. gibsoni that seen in R. sanguineus (13.16%) and H. anatolicum (2.56%). Based on phylogenetic analysis data of five local B. gibsoni isolates, this study demonstrated their closely relations to the global NCBI-BLAST B. gibsoni Iraqi isolate (ID: MN385424.1).
Conclusion:
This represents the first Iraqi study demonstrated molecularly B. gibsoni in different species of ticks that infected stray dogs.

Published: September 2024

Background:
Ultrasonography is not chosen as the common imaging modality to diagnose spinal cord diseases. The present report indicates good diagnostic efficacy of ultrasonography for identifying spinal cord compressed by subcutaneous mass when scanning through the defected vertebral laminae and spinous process.
Case Description:
A five-month-old female Holstein calf presented with progressive hindlimb paralysis following a surgical resection of back mass conducted at 21 days of age. The mass was subsequently histopathologically diagnosed as a pulmonary choristoma. Alongside hindlimb paralysis, the calf developed a swollen back at the lumbar region where the mass was removed. This suggested regrowth of the resected mass, causing injury to the underlying spinal cord. Ultrasonography identified the subcutaneous involvement of the capsular mass, which had three anechoic cavities separated by the echogenic septal structures. The spinal cord could be ultrasonographically demonstrated as adjacent to the mass through the defected vertebral laminae and spinous process in the second and third lumbar vertebras. Ultrasound-guided centesis allowed collection of purulent exudates in which Escherichia coli was isolated. Myelography and subsequent computed tomography revealed a partial blockage of the intradural flow of contrast media at the levels of the second and third lumbar vertebras, diagnosed as spina bifida on the computed tomographic images. When applying ultrasonography to the spinal cord within a saline pool soon after the subcutaneous abscess was successfully resected, the spinal cord was characterized by the interrupted and partly-extended hyperechogenic line of the central canal within the echogenic parenchyma. The echotexture of the spinal cord showed damage due to compression from the subcutaneous abscess. The animal had a sub-optimal postoperative outcome, including limited improvement of the neurological signs.
Conclusion:
In the present case, combining ultrasonography, radiography (myelography) and computed tomography was very effective for diagnosing spina bifida, with the subcutaneous abscess inducing spinal cord compression. Additionally, using intraoperative ultrasonographic scanning to evaluate the degree of spinal cord damage can contribute to predicting the postoperative outcome.
