Abstract

Sargassum is the most diverse genus in the brown algae Fucales and represents key ecologically important processes in marine ecosystems. There are 150 species found in tropical, subtropical and boreal waters. This study aims to know the biodiversity of the Sargassum genus in Lendang Luar Beach, West Nusa Tenggara. The study results will give knowledge about the different species of Sargassum based on their different morphologies and anatomical structures. The research method is divided into three work stages, which are collected on the location site, observing forms and observing anatomy. It collects algae by random sampling and serving cauloid, filoid, Vesicle (float) and receptacle (organs of breeding). Anatomical observation of the cortex and pith parts of stalk and thallus of Sargassum. According to the observation, four species of Sargassum were found at Rendang Luar Beach, North Lombok, West Nusa Tenggara: Sargassum crassifolium, Sargassum cristaefolium, Sargassum echinocarpum, and Sargassum polycistum. Such a result is that the variation in morphology is supported by the variation in anatomy.

Abstract

The chronic condition known as thalassaemia is a hereditary ailment that results in the loss or decreased synthesis of one or more globin chains in erythrocytes. Ineffective erythropoiesis, early erythrocyte breakdown, and anaemia are all possible outcomes of thalassaemia. In Indonesia, it is estimated that between 3-10% of people have β thalassaemia, whereas between 2.6-11% have α thalassaemia. Approximately 2,500 newborns are thought to be born with β-thalassemia major each year. The purpose of this study is to identify the variables that affect the quality of life for kids with thalassaemia so that the right kind of medication can be developed to lessen this issue. This study used the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) technique to conduct a literature review. The PubMed and ScienceDirect databases were used to conduct online searches for the literature. Three articles in all were chosen for examination based on search results that satisfied the inclusion requirements. The study findings from the three analysed publications indicate that the primary factor influencing a child's declining quality of life is school function. Children's age, the kind of iron chelation treatment, the frequency of transfusions, the number of family members with thalassaemia, and haematopoietic stem cell transplant operations are all factors that affect the quality of life of patients with thalassaemia. Based on the factors that influence the quality of life of children with thalassemia, the role of parents supported by the government and community is needed in the treatment of children with thalassemia.

Abstract

This study examines the growth of the Pharella acutidens clam in mangrove ecosystem of  Cempi Bay, which has a habit of living in the substrate with a vertical shell position. These clams emit siphons when the hole they live is waterlogged to obtain food. Field observations showed that the depth of the Pharella acutidens hole was strongly influenced by the tide. During high tide, the clam moves close to the surface up to 10 cm from the substrate, while during low tide, the clam can bury itself to a maximum depth of 70 cm and a minimum of 25 cm. The minimum shell length recorded was 4.90 cm, while the maximum length of Pharella acutidens clams was 9.30 cm. the highest L∞ (9,71) and K (0.45) is found in locations that are densely vegetated, the lowest L∞ (7,88) and K (0.38) is found in low vegetated locations. There is something interesting because the low-vegetated location and higher disturbance has a relatively high recruitment value.

Abstract

Secondary metabolites from actinobacteria have been known to have many potentials as antioxidants, antibiotics, anti-cancer, and others. Various studies have been conducted and published regarding the findings of the potential of actinobacteria. This study aims to determine the development of research related to the potential of actinobacteria originating from mangrove areas and their secondary metabolites as natural antibiotics with bibliometric methods assisted by the VOS Viewer application. The articles used in this study are articles published from 2014 to 2024 and taken from the PubMed database. A total of 78 articles analyzed with VOS Viewer showed that over the past decade, the development of research on this topic still revolves around actinobacteria, microbial sensitivity tests, anti-bacterial agents, and Streptomyces as indicated by the high occurrence of these words in the titles and abstracts of the articles analyzed. The potential for research development can be directed at antineoplastic agents, cell proliferation, and mass spectrometry because the use of these terms is still minimal. However, analysis using other databases is needed as a comparison to get clearer results related to the development of research on the potential of actinobacteria derived from mangroves and their secondary metabolites as antibitoics.

Abstract

Basal cell carcinoma (BCC), previously referred to as basal cell epithelioma, this is the most prevalent cancer in people. Rarely can BCC form on mucosal membranes or on the palms and soles; it usually appears on sun-damaged skin. Metastasis is uncommon in basal cell carcinoma, which typically grows slowly. BCC is rarely lethal, but when therapy is insufficient or delayed, it can be extremely damaging and damage local tissue. BCC typically manifests clinically as a pink or flesh-colored pearly papule with telangiectatic or ulcerated arteries. Although it can also affect the limbs, BCC usually affects the head or face. Case report: A 70-year-old woman came to the dermatovenerology polyclinic in Makassar city with complaints of a lump on her nose that had been getting bigger and sometimes bleeding. The size of the tumor lesion was about 1.5 cm, excision of the lesion was performed under local anesthesia considering that there was impaired lung function from the chest X-ray. Follow-up 5 days before wound closure while waiting for the biopsy results, bleeding was minimal and the biopsy results showed pigmented basal cell carcinoma with tumor-free edges. Closure of excision wound with simple suture showed good suture viability, without signs of tissue necrosis or infection at the previous lesion site. Treatment of basal cell carcinoma (BCC) is highly dependent on the anatomical location and histologic characteristics of the lesion. Excision was performed due to its high-risk location on the face.

Abstract

Systolic and diastolic blood pressure readings of 140 mmHg and 90 mmHg, respectively, are indicative of hypertension, a condition that can lead to major consequences like heart attacks, strokes, and early death. The prevalence of hypertension increased significantly in 2018, reaching 1.3 billion individuals worldwide. This study aims to determine the relationship between smoking habits, sleep quality, and dietary patterns with the incidence of hypertension in the Working Area of Teruwai Community Health Center, Pujut Subdistrict, Central Lombok Regency, during the period of August 20–31, 2024. The study utilized a cross-sectional design with a sample size of 108 respondents, selected through simple random sampling. The statistical test employed was the chi-square test. The results found 76 respondents (70.4%) had high blood pressure. Hypertensive behavior and smoking significantly correlated (p-value = 0,000). Likewise, there is a significant relationship between food patterns and hypertension (p-value = 0,000) and sleep quality and hypertension (p-value = 0,000). The conclusion is that risk factors for hypertension include smoking habits, sleep quality, and dietary patterns, all of which significantly influence the incidence of hypertension.

Abstract

Mataram City, the capital city of West Nusa Tenggara Province, is experiencing rapid development which has an impact on increasing noise in urban areas. This study aims to analyze the ability of vegetation to reduce noise in the Udayana Urban Forest. This study uses a quantitative descriptive method, with location selection using purposive sampling. Noise reduction measurements using a Sound Level Meter at four observation points with variations in canopy cover and the distance variable of vegetation from the noise source. This study shows that vegetation has an essential role in reducing noise, with a noise level reduction value in the open dominance area of ​​the eastern area of ​​8.2 dBA and the western area of ​​8.7 dBA. At a sparse vegetation density level, a decrease of 6 dBA in the western and eastern areas is constant. At a moderate vegetation density level, a decrease of 4.5 dBA in the western and eastern areas, the noise value is constant. In vegetation with high/dense density, there was a decrease of 5.9 dBA in the eastern and western areas of ​​7.1 dBA. Based on the distance variable, noise reduction in the open dominance area decreased by 6.1 dBA in the eastern area and 6.7 dBA in the western area. In areas with sparse vegetation density, there was a decrease of 6.8 dBA in the East and 6 6.0 dBA in the West. For moderate vegetation density, there was a decrease of 6.4 dBA in the East and 6.1 dBA in the West. In areas with high/dense vegetation density, there was a decrease of 3.6 dBA in the East and 4.4 dBA in the West. The regression analysis results showed that canopy cover and distance significantly affected noise levels with a strong relationship, where the denser the canopy cover and the farther the distance, the noise level would decrease.

Abstract

The Papuan indigenous plant Cryptocarya massoy (Oken) Kosterm has substantial commercial significance as an essential oil source. Plant growth regulators (PGRs) are essential for regulating growth responses including callus development, and tissue culture offers a viable means of reproducing this species. Kinetin, a cytokinin-type PGR, is particularly important in promoting cell division and callus development. This study aimed to evaluate the growth response of C. massoy explants under varying kinetin concentrations and determine the optimal concentration for callus induction. The experiment utilized a Completely Randomized Design (CRD) with three kinetin treatments: 0.5 mg/L (A), 1.0 mg/L (B), and 1.5 mg/L (C). Results showed that 1.0 mg/L kinetin achieved the highest explant survival rate (71%) and the lowest browning rate (8%), compared to 13% browning at 0.5 mg/L and 1.5 mg/L. However, the highest callus formation (0.25 average callus) with a compact, brownish texture was observed at 1.5 mg/L. The 0.5 mg/L concentration consistently exhibited the lowest response across all parameters. These findings indicate that 1.0 mg/L kinetin is optimal for enhancing explant survival and minimizing browning, while 1.5 mg/L is more effective for inducing callus formation, underscoring the importance of kinetin concentration in optimizing C. massoy tissue culture protocols.
