Abstract

Lung cancer is one of the leading causes of cancer death worldwide, with mortality rates continuing to rise annually. According to WHO data in 2021, approximately 1.8 million deaths were caused by lung cancer, making it a significant global health problem. In Indonesia, the prevalence of lung cancer is also increasing, especially in the elderly and among active and passive smokers. Radiotherapy is one of the main modalities in the management of lung cancer, especially for patients who cannot undergo surgery. With technological advances, Intensity-Modulated Radiation Therapy (IMRT) was developed to improve the precision of radiation dose delivery while still protecting healthy tissue around the tumor. This study aims to systematically review the literature on the effectiveness and safety of Intensity-Modulated Radiotherapy (IMRT) compared with conventional techniques, such as Three-Dimensional Conformal Radiotherapy (3D-CRT). The method used was a Systematic Literature Review (SLR) following the PRISMA 2020 guidelines for international articles published in the last five years (2019–2024). Research results show that IMRT can reduce radiation doses to vital organs such as the heart, contralateral lung, and spinal cord, while reducing cardiopulmonary toxicity without compromising tumor control. IMRT derivative techniques such as Volumetric Modulated Arc Therapy (VMAT) and Simultaneous Integrated Boost IMRT (SIB-IMRT) have also been shown to improve radiation accuracy and patient quality of life. IMRT is an important innovation in radiation oncology that is effective, safe, and has the potential to become the gold standard for lung cancer radiotherapy in the future.

Abstract

Head trauma is an injury caused by impact or mechanical force to the head that causes temporary or permanent brain dysfunction. Rapid and accurate evaluation is essential for determining appropriate treatment. CT scanning is the primary modality in the initial assessment of head trauma due to its widespread availability, speed of examination, and ability to detect acute intracranial hemorrhage. Conversely, MRI provides higher soft-tissue resolution and is highly sensitive for detecting diffuse axonal injury or contusions that are not visible on CT scans. The identification stage was conducted by searching the literature using keywords such as "head trauma," "traumatic brain injury," "CT scan vs MRI," "diagnostic accuracy of CT," and "MRI diffuse axonal injury." The screening process involved selecting articles based on titles and abstracts and excluding duplicates, non-clinical studies, non-scientific journal publications, and studies without quantitative data. Successful articles then proceeded to the eligibility stage with a full-text review to ensure that the studies directly addressed the diagnostic performance of CT scanning and MRI in head trauma cases. This demonstrates the importance of both modalities, each with its own advantages. MRI has higher sensitivity and accuracy in detecting non-hemorrhagic parenchymal lesions such as diffuse axonal injury (DAI), contusions, and microhemorrhages. Conversely, CT scans are superior in detecting acute hemorrhage, skull fractures, and cerebral edema that require immediate treatment. MRI is superior for detecting non-hemorrhagic lesions, but CT remains the first choice in the acute phase. The combination of the two provides the most comprehensive diagnostic evaluation.

Abstract

Lumbosacral Transitional Vertebra (LSTV) is a congenital anatomical variation at the transition between the last lumbar vertebra and the sacrum that can affect the biomechanics of the lumbosacral spine. These biomechanical changes may increase mechanical stress on the overlying vertebral segments and accelerate lumbar disc degeneration. Lumbosacral disc degeneration is a major cause of low back pain, with high prevalence in the productive-age population and an impact on quality of life and productivity. Magnetic Resonance Imaging (MRI) is an imaging modality with high accuracy for evaluating soft-tissue structures of the spine, thereby playing an important role in identifying LSTV and assessing the degree of disc degeneration. This study used a systematic literature review method to analyze the relationship between LSTV and lumbar disc degeneration based on MRI findings. A literature search was conducted in PubMed, Google Scholar, ScienceDirect, and ResearchGate databases using the keywords "Lumbosacral Transitional Vertebra", "LSTV", "Lumbar Disc Degeneration", and "MRI". The obtained articles were then selected based on predetermined inclusion and exclusion criteria. Of the 252 articles found, 38 met the criteria for further analysis. The review results showed that most studies reported an increased risk of lumbar disc degeneration in individuals with LSTV, particularly in the segments cranial to the transitional vertebrae, such as L4–L5. These findings suggest that LSTV may affect biomechanical load distribution in the lumbosacral spine. Therefore, identifying LSTV via MRI is important in evaluating patients with low back pain to help determine structural risk factors and support more appropriate management planning.

Abstract

The Palapa Ring project has built several large rings in Indonesia, but the 11 connecting Sulawesi and NTT remain unfinished. Regarding this issue, the optical backbone network from Makassar to Maumere, as part of the 11 ring sections, is designed using Dense Wavelength Division Multiplexing (DWDM) technology. The method used in writing this scientific journal is to collect initial data on the geographic map of the Bangka–Belitung Islands Province (BABEL) in the island of Sumatra. To collect data on geographic information and regional characteristics of the Bangka – Belitung Islands Province, especially the number of cities and regencies in the province. The author uses Google Maps software and Google's Wikipedia data. Then, creating a district segment to facilitate network calculations by Optical Link Power Budget (OSNR), Optical Signal-to-Noise Ratio (OSNR), and Optical Rise Time Budget (ORTB) values. After that, a design is carried out using OTN Planner Software. From the results of the design and simulation of the backbone network, it was found that the value of the Optical Link Power Budget (OLPB) < 50 dBm where this value is the ideal value in the deployment of the DWDM OTN backbone network, and the range of the Optical Signal Noise Ratio (OSNR) ranges from 20 dBm < OSNR < 40 dBm, which is the ideal value of OSNR, and has an Optical Rise Time Budget (ORTB) value < 60 ps, ??and also has a segment margin system> 7 dB. The results of the simulation and analysis, as well as the calculation of the OLPB and OSNR values, show that the DWDM OTN infrastructure development project in the Bangka-Belitung Islands province is highly feasible to implement as a sustainable, ongoing project.

Abstract

Cholesterol is a lipid that plays important roles in the body, but high levels can cause various health problems, including atherosclerosis and cardiovascular disease. Consuming high-saturated-fat, low-fiber instant foods, such as instant noodles, can affect blood cholesterol levels. Instant noodle consumption among students tends to increase due to practicality, affordability, and ease of preparation. However, instant noodles generally contain saturated fat, sodium, and food additives that can raise blood cholesterol levels when consumed in excess. This study aims to determine the picture of total cholesterol levels in students at Abdurrab University. The research design is descriptive, with a cross-sectional approach. The study sample was selected using purposive sampling, comprising 30 students who consume instant noodles at least twice a week. Total cholesterol levels were examined using the CHOD-PAP enzymatic method. The research method used in this study is CHOD-PAP, which uses venous blood or serum samples. The study found that 17 respondents had normal total cholesterol levels, 6 had moderate levels, and 7 had high levels. It can be concluded that respondents with high total cholesterol levels frequently consume instant noodles when staying up late, more than 3 to 4 times. In contrast, respondents with normal cholesterol levels do not frequently consume instant noodles, only once a week.

Abstract

Butterfly pea (Clitoria ternatea), also known as butterfly pea, is a climbing plant from the Fabaceae family that has great potential as a source of natural antibacterials. This plant contains various bioactive compounds, including alkaloids, tannins, saponins, anthocyanins, and phenolics, which contribute to its antibacterial activity. This study aims to evaluate the inhibitory effect of butterfly pea flower extract on Staphylococcus aureus growth and to analyze the relationship between extract concentration and antibacterial activity. The research method used a diffusion test with treatment variations in extract concentration (25%, 50%, and 75%), as well as a positive control (chloramphenicol) and a negative control (Aquadest. The diameter of inhibition (DDH) was measured with a caliper to ensure accuracy. In addition, phytochemical screening was performed to identify the active compounds in the extract. The results showed the presence of flavonoids, tannins, alkaloids, phenols, and saponins, all of which act as antibacterial agents. The antibacterial test results showed that butterfly pea flower extract significantly inhibited the growth of Staphylococcus aureus, with a highly significant difference in inhibitory activity across concentrations. The highest antibacterial activity was observed at 75% concentration, with an average DDH of 26.53 mm, placing it in the very strong inhibitory power category. Increasing the extract concentration is consistent with increased antibacterial effectiveness. Butterfly pea flower extract has the potential to be developed into an effective, safe, natural antibacterial alternative.
