Published: August 2024

Numerous ancient cultures acknowledged the magnetic properties of magnets and utilized them as pain-relieving amulets. The Vedas, India's sacred books, discuss the use of magnets to control bleeding and treat specific female body ailments. Paracelsus, an alchemist and physician from the 16th century, discovered that magnets may cure most inflammations and ulcers, as well as many ailments of the bowel and uterus, and that they are beneficial for both internal and external illnesses. In the 18th century, Dr. Samuel Hahneman, the inventor of homeopathy, declared that "a magnetic wand can quickly and definitively cure a severe disease if it is brought close to the body." Magnetized water is also used well to treat assimilation issues (such as calcium and magnesium deficiencies and iron deficiency anemia). Magnetized water promotes early germination in the three species of legumes. The number of germinated seeds on the eighth day is the same for bean seeds watered with ozonated and magnetized water, and there are no significant variations between seeds irrigated with ozonated, filtered, and magnetized water.

Authors: Elake Welminci , Riry Johan , Riry Roberth Berthy
Published: August 2024

Cocoa was introduced to Indonesia in 1560, first in Sulawesi, Minasa. Early exports from Manado to Manila in 1825-1838 reached 92 tons, but pest attacks damaged it. By 1928, Ambon had 10,000-12,000 cocoa trees producing 11.6 tons. Maluku, with 1,398,672 hectares of land, offers significant investment potential in the cocoa sector. In Makububui Village, cocoa is the backbone of the economy, but farmers face challenges like pests, climate change, and price fluctuations. Research in Makububui is crucial to improve cocoa productivity and support farmers with more effective policies. The goal is to understand cocoa plant management by local farmers. Descriptive research on cocoa plant management in Makububui Village, West Seram, involves 12 farmers for a month. It focuses on cocoa cultivation practices, including seed preparation, planting, maintenance, and harvesting. Data collection methods include observation, questionnaires, interviews, and documentation. Data analysis uses a descriptive approach with presentation in frequency distribution tables. Traditional cocoa management practices include watering, fertilization, pruning, and grafting. However, there is room for improvement, especially in marketing and pest control. Integration of modern technology and broader market access are needed to increase productivity. This research provides insights into cocoa management in rural areas, with recommendations for training and collaboration between government and institutions

Published: August 2024

This study aims to evaluate and provide recommendations regarding the empowerment of clean water in Waur Village, Kei Besar District, Southeast Maluku Regency. Although Waur Village has a significant population of 366 households or 1,569 people, efforts by the local government and relevant private institutions to manage clean water are still minimal. This study focuses on three main water sources, namely Faderni, Metan Evav, and Snalut, which often experience drought during the dry season, making it difficult for the community to obtain clean water. The methodology used includes field observations, interviews with respondents, and water sample testing conducted by the Health and Calibration Laboratory Center of Maluku Province. The results of the study show that the three water sources do not yet have adequate facilities, with leaking and uncovered reservoirs, and there is no empowerment process such as water sampling for feasibility testing or health socialization programs related to water management. Water sample tests indicate that water from Faderni, Metan Evav, and Snalut springs has good odor and taste parameters (No Odor and No Taste) and a color level that is still suitable for consumption. This study is expected to be a consideration for relevant parties in making more effective and efficient efforts to empower clean water in Waur Village

Published: August 2024

Until now, the treatment of allergic rhinitis has not been satisfactory. Patients with allergic rhinitis are highly dependent on medical pharmacological treatment. Nasal irrigation is expected to help reduce symptoms due to decreased eosinophil counts and recurrence of allergic rhinitis. This study aims to determine the effect of nasal irrigation on eosinophils and the recurrence of allergic rhinitisâ€”experimental research by pre â€“ post-test group design. Twenty samples of allergic rhinitis patients were trained to wash their nose once a day at homeâ€”nasal mucosal secretion was collected to count eosinophils before and after intervention. The degree of recurrence was assessed based on the symptoms of nasal congestion, runny nose, sneezing, and itchy nose. The degree is divided into three groups: decrease, remain, and increase. The statistical analysis used in this study for bivariate analysis was Wilcoxon Test. There was a significant decrease in eosinophil count (p = 0.00) and recurrence of nasal congestion (p = 0.00), runny nose (p = 0.00), sneezing (p = 0.001) and itchy nose (p = 0.00) in allergic rhinitis after nasal irrigation intervention. Nasal irrigation treatment can help decrease eosinophil count and recurrence of allergic rhinitis.

Published: August 2024

Validation of culture results based on direct gram stain plays a vital role in differentiating pathogens' cause of infection or colonization in pneumonia cases. Our study aims to evaluate the validation of diagnostic microbiology based on gram stain and culture compared to chest radiography in critically ill patients with suspected pneumonia. This was a single-center retrospective data analysis in the Intensive Care Unit at Secondary Care Hospital in Central Java. The quality of sputum was determined by using a Modification Criteria of Bartlett and a Semi-Quantitative Score. The results of sputum culture with neutrophils count > 10 and bacterial count > 2 per field in Gram stain were considered the presumptive pathogen. Seventy sputum specimens were collected; however, only 58 were selected for further analysis in this study. In sputum specimens with Bartlett score +2 and Semi-Quantitave score 3 or 4, the chest x-ray results of all patients had positive infiltrates (100%). Diagnostics accuracy of the results of clinical microbiologist examination with chest X-ray had a sensitivity of 90%, specificity of 60.71 %, accuracy of 65.5%, a positive predictive value of 61.36%, a negative predictive value of 78.6%. It was concluded that validation of diagnostic microbiology based on gram stain and culture had susceptible and adequately specific results to differentiate between presumptive pathogens from colonization in pneumonia cases.

Authors: Purnomosidi Muhammad Abhi , Sjatha Fithriyah , Yasmon Andi
Published: August 2024

Acute respiratory infections (ARIs) are the highest cause of death in children in the world. Based on the 2018 Riset Kesehatan Dasar Nasional, ARI cases in Indonesia showed a prevalence of 4.4%, with the highest cases occurring in children. One of the new viruses first identified in 2005 in human nasopharyngeal samples is the human bocavirus (HBoV). HBoV is a single-strand DNA virus belonging to the Parvoviridae family. This study aimed to assess the prevalence of HBoV in children presenting with ARI during the transitional period of the Covid-19 era. HBoV detection was conducted using multiplex PCR and reverse hybridization methods on nasopharyngeal and oropharyngeal swab samples collected from symptomatic children. This study reported a prevalence rate of 4.94% for HBoV in 2022 and 5.04% in 2023. Furthermore, the study identified favorable detection rates for HBoV in children with ARIs as 14.81% in 2022 and 8.45% in 2023. These rates ranked 2nd and 5th highest among other pathogens detected in ARIs. Additionally, there was an increase in positive HBoV samples from 4 samples in 2022 to 6 samples in 2023, which was attributed to the relaxation of nonpharmaceutical Covid-19 interventions by mid-2022. HBoV was identified at a significant rate among children with ARI in Jakarta during the transitional phase of the Covid-19 era (2022-2023). Given its potential to induce severe ARI, HBoV necessitates heightened attention as an etiological agent.

Diketahui ubi jalar kuning mengandung karbohidrat, mineral, antioksidan, dan serat. Penelitian ini bertujuan untuk mengetahui pengaruh persentase ubi jalar kuning terhadap hasil uji organoleptik dari segi warna, aroma, rasa, tekstur, dan penampilan. Metode yang digunakan yaitu uji hedonik untuk mengetahui tingkat kesukaan dan formulasi terbaik. Skala hedonik menggunakan 5 skala tingkat kesukaan yaitu skor 1: sangat tidak suka, 2: tidak suka, 3: netral, 4: suka, dan 5: sangat suka. Formulasi produk Brownis dengan persentase substitusi ubi jalar kuning yaitu 0%, 25%, dan 50%. Hasil penelitian menunjukkan, formulasi substitusi tepung ubi jalar kuning 25% adalah produk yang paling disukai panelis beradasarkan nilai hedonik rasa, tekstur, penampilan dan warna. Sehingga dapat disim- pulkan bahwa produk Brownis dengan penambahan ubi jalar kuning 25% adalah formulasi terbaik berdasarkan uji hedonik pada penelitian ini. Penelitian ini berkontribusi dalam menyediakan solusi praktis untuk meningkatkan nilai gizi produk brownis.
