Abstract

Indonesia faces serious challenges in managing domestic waste, especially organic waste, which constitutes the largest component of the total national waste generation. One innovative form of recycling is the fermentation of organic waste into eco enzymes, which are fermented liquids capable of producing various active enzymes such as protease, amylase, and lipase with broad ecological benefits. This study aims to observe the activity of protease, amylase, and lipase enzymes in eco enzyme solutions made from fruit waste, and compare the results with previous studies to analyze the potential application of eco enzymes as efficient, economical, and sustainable natural bioremediation agents. The fermentation process was carried out for 90 days, while enzyme activity was analyzed using spectrophotometry and titration methods. The results showed protease activity of 261 U/mL, amylase of 21.53 U/mL, and lipase of 3.46 U/mL. These values are relatively high compared to several previous studies, indicating that fruit waste is an effective substrate for eco enzyme production. Thus, it can be concluded that eco enzyme has great potential in reducing pollutants such as heavy metals, BOD, COD, TSS, and helping to stabilize pH, thereby playing an important role in the treatment of domestic waste and small-scale industrial waste. The recommendation from this study is the need for further research related to the optimization of substrate composition.

Abstract

More than 90% of individuals infected with Human Immunodeficiency Virus (HIV) exhibit skin abnormalities that can serve as important clues for early diagnosis, monitoring disease progression, and assessing the effectiveness of antiretroviral therapy (ART). However, the diverse presentation of skin problems often complicates clinical management. Methods: This article is based on a literature review of various international and national publications on skin manifestations in HIV patients, as well as dermatological management guidelines. The analysis focused on the types of skin infections, non-infectious conditions, side effects of ART, and recommended treatment strategies. Results: The literature review revealed that skin problems in HIV patients include fungal infections (such as candidiasis, dermatophytosis), bacterial (CA-MRSA, syphilis), viral (HSV, VZV, HPV, molluscum contagiosum), and non-infectious conditions such as seborrheic dermatitis, psoriasis, and severe drug reactions. These skin conditions are influenced by a weakened immune system, treatment side effects, and socioeconomic factors. Treatment requires a combination of ART therapy, dermatological care tailored to the type of skin problem, and psychosocial support. Conclusion: Skin manifestations in HIV patients reflect their immune system and quality of life. Comprehensive treatment, including ART, dermatological therapy, and a psychosocial approach, has been shown to be effective in reducing morbidity and stigma. The results of this study underscore the importance of interdisciplinary collaboration to improve treatment outcomes for HIV patients with skin problems in Indonesia.

Abstract

Chronic Lymphocytic Leukemia (CLL) is a slowly progressing hematological cancer characterized by the accumulation of abnormal B lymphocytes in the blood, bone marrow, and lymphatic tissue, commonly affecting the elderly. This review aims to comprehensively review the epidemiology, molecular basis of the disease, clinical symptoms, diagnosis, and therapeutic advances of CLL, emphasizing the importance of shifting treatment approaches towards more precision therapy. A literature search was conducted through PubMed, Scopus, and Web of Science using the keywords "Chronic Lymphocytic Leukemia", "epidemiology", "molecular basis of the disease", and "targeted therapy", with publication criteria between 2018–2025, full text, and topic relevance. Analysis was conducted using a narrative review and thematic synthesis approach to identify epidemiological trends, therapeutic effectiveness, and clinical implications. The results showed that the incidence of CLL is higher in Western countries compared to Asia, with a higher prevalence in elderly men. The main genetic factors that play a role include del(13q), del(17p), and TP53 mutations. Over the past decade, targeted therapies such as second-generation Bruton's tyrosine kinase inhibitors (acalabrutinib, zanubrutinib) and the venetoclax-obinutuzumab combination have been shown to improve remission rates with fewer side effects compared to chemoimmunotherapy. Minimal Residual Disease (MRD) status has become an important marker for determining when therapy can be stopped early. In conclusion, this review underscores the crucial role of biomarkers and MRD in modern CLL management. Future developments include the integration of personalized therapy approaches and translational research to develop more effective and safe treatment strategies.

Abstract

Fusarium wilt disease caused by Fusarium oxysporum f.sp. cubense (Foc) represents a major constraint to banana production, leading to severe yield and quality losses. The use of biological control agents (BCAs) such as Streptomyces and Bacillus offers an environmentally sustainable alternative to manage this pathogen. This study aimed to evaluate the antagonistic activity, culture filtrate effects, volatile organic compounds, and compatibility of Streptomyces S01, Bacillus B01, and Bacillus B16 isolates against Foc under in vitro conditions. A completely randomized design (CRD) with three replications was employed. Results indicated that Streptomyces S01 was the most effective isolate, achieving 84.12% inhibition in the dual culture assay, 69.96% in the culture filtrate test, and 41.4% through volatile compound activity. Isolates Bacillus B16 and Bacillus B01 showed moderate efficacy, with Bacillus B16 exhibiting superior performance in the volatile assay (28.8%). Compatibility tests revealed that Streptomyces S01 + Bacillus B16 and Bacillus B01 + Bacillus B16 were mutually compatible, while Streptomyces S01 + Bacillus B01 displayed incompatibility. These findings suggest that Streptomyces S01, particularly in combination with Bacillus B16, holds strong potential as a microbial consortium for the biological control of Fusarium wilt in banana cultivation.

Abstract

Leukemia is a cancer that originates from cells that initially develop into blood cells. Leukemia can be classified as acute or chronic, depending on how quickly the disease appears and how it progresses in the body. This literature review aims to determine the treatment for patients with AML depending on the subtype. This literature review used journal review methods and data searches through various sources. The results of the literature study found that Acute Myeloid Leukemia (AML) is divided into six subtypes. AML is caused by clonal transformation of hematopoietic cells through chromosomal abnormalities and gene mutations, with risk factors including exposure to radiation, benzene, smoking, chemotherapy therapy, the development of chronic myeloid neoplasms, aging, and predisposing diseases. Diagnosis of AML involves peripheral blood and bone marrow analysis, immunophenotyping, cytogenetics, molecular cytogenetics, and imaging to detect the presence and characteristics of leukemic cells. Treatment of AML includes induction therapy, consolidation therapy, and response monitoring, with special considerations for the selection of chemotherapy regimens, stem cell transplantation, and transfusion support to manage associated complications. In conclusion, Acute Myeloid Leukemia (AML) is a condition in which myeloblasts undergo excessive proliferation and fail to differentiate into granulocytes. This condition causes the bone marrow to fill with myeloblasts.

Abstract

Seaweed is a marine commodity with high economic value and is widely used in the food industry. However, its high water content, cultivation environment conditions, and post-harvest handling make seaweed susceptible to microbial contamination, including Escherichia coli, necessitating quality testing to ensure food safety. Previous studies have focused more on general microbiological quality, without emphasizing the identification of Escherichia coli or the determination of Total Plate Count (TPL) as an indicator of the number of mesophilic aerobic bacteria. To fill this gap, this study was conducted to identify Escherichia coli using qualitative tests. There are two stages of testing: a presumptive test using MMGM media and a confirmatory test using TBX media. While TPL was determined using the duplo dilution method, the pour plate technique, and the plate count. The presumptive test results showed that all seven samples were suspected to be positive for Escherichia coli, but were declared negative in the confirmatory test. Meanwhile, the TPL results showed that two samples exceeded the standard, namely sample D and the Escherichia coli sample.

Abstract

Tonsillitis is an inflammation and infection of the palatine tonsils, typically caused by viral or bacterial pathogens. It commonly affects children aged 5 to 15 years and has a high prevalence rate in Indonesia, with chronic tonsillitis accounting for 3.8% of ENT cases. This literature review aims to explore the etiology, clinical manifestations, diagnostic approaches, and treatment options for acute tonsillitis. The method used in this paper is a literature-based descriptive analysis drawn from national and international medical sources. The main etiological agent is Group A beta-hemolytic Streptococcus, although viruses like Epstein-Barr Virus (EBV) also play a significant role. Clinical symptoms include sudden fever, sore throat, odynophagia, halitosis, dysphagia, and swollen lymph nodes. Diagnosis is established through clinical history, physical examination using Brodsky's Tonsil Scale, and confirmatory laboratory tests such as throat swab culture. Management of acute tonsillitis includes both pharmacological interventions, such as amoxicillin or clarithromycin, and non-pharmacological strategies including tonsillectomy for recurrent or chronic cases. The review concludes that proper diagnosis and evidence-based treatment are essential to prevent complications and recurrence. Furthermore, public education on personal hygiene and infection control can significantly reduce transmission. This study underscores the importance of comprehensive clinical evaluation and rational antibiotic use in managing acute tonsillitis, particularly in areas with high disease prevalence.

Abstract

The blue butterfly pea flower (Clitoria ternatea) is a medicinal plant rich in bioactive compounds, including anthocyanins and flavonoids, with health benefits and potential in the food and cosmetics industries. There has been no scientific study on the non-specific parameters of cultivated butterfly pea flowers and their simple quality related to the environmental conditions in the village. Standardization of non-specific parameters, such as moisture content, ash content, and microbial contamination, is crucial to ensure the quality and safety of butterfly pea-based products. This research aims to analyze the non-specific parameters of butterfly pea in support of developing quality standards suitable for the pharmaceutical and cosmetic industries. The research method uses experimental techniques, starting with sample collection, laboratory analysis, and data analysis. The results of the water-soluble ash test, 99.63% indicate contamination by inorganic compounds that dissolve in water, while the acid-insoluble ash content of 0.09% suggests minimal contamination by silica. The water-soluble extract content of 54.98% and the ethanol-soluble extract content of 99.98% indicate the solubility of compounds in solvents, which are important for the extraction and formulation of traditional medicine products or herbal products that use water and ethanol as solvents. In conclusion, the results of non-specific parameter tests on the blue butterfly pea flower simplicia from Cipangeran Village indicate that the simplicia has excellent physicochemical qualities.
