Abstract

Gili Gede hosts a vital mangrove ecosystem, essential for the community and protecting coastal areas from large waves. However, increasing development and human activities in and around the mangrove areas threaten their distribution and extent. This study aims to map the spatial distribution, density, and area of mangroves on Gili Gede. Sentinel-2A satellite imagery was utilized with the Normalized Difference Vegetation Index (NDVI) method, and the image data were validated using hemispherical photography. Environmental parameters measured included sediment salinity, temperature, pH, humidity, NPK nutrients, and substrate type. Additional data were gathered on slope, buffer distances, and through semi-structured interviews using purposive sampling. The findings revealed that the mangrove density on Gili Gede is predominantly sparse, covering 15.56 hectares or 77.07% of the total mangrove area. Medium-density mangroves span 3.45 hectares or 17.09%, while dense mangroves occupy the smallest area, 1.18 hectares or 5.84%. Mangroves are distributed across the northern, western, and eastern sides of Gili Gede. The study identified 22 species of mangroves, both true and associated, across 14 families. Environmental factors influencing the distribution, density, and extent of mangroves across three locations include sediment salinity, temperature, pH, humidity, and nutrient content (NPK), as well as substrate type, slope, and anthropogenic influences such as human activities and the proximity of settlements to the mangrove ecosystem.

Abstract

Infectious diseases are diseases caused by bacteria. Several bacterial infectious diseases include bacteria that cause skin infections such as Staphylococcus aureus, Staphylococcus epidermidis, Propionibacterium acnes and Streptococcus pyogene, nosocomial pneumonia infections of the urinary tract by Pseudomonas aeruginosa and Klebsiella pneumoniae that cause Healthcare-Acquired Infections (HAIs). The drugs usually used to treat bacterial infections are antibiotics. Along with the increase in cases of infection, there is also an increase in the use of antibiotics. Widespread or irrational use of antibiotics can cause resistance, so alternatives are needed to overcome them. One plant that has potential as an antibacterial agent is the leaves of Chinese Ketepeng (Cassia alata L.). Chinese ketepeng leaves contain phytochemical compounds, namely flavonoids, saponins, tannins, alkaloids and phenols. Therefore, this literature review aims to determine the potential of Chinese Ketepeng (Cassia alata L.) leaf extract as an antibacterial agent. The method used is the Systematic Literature Review method by collecting data through databases such as Publish or Perish, PubMed, and Google Scholar. The search method uses the keywords "Chinese Ketepeng Plant", "Skin infection", "Antibacterial", "Disc diffusion", "Well diffusion", "Staphylococcus aureus", "Staphylococcus epidermidis", "Klebsiella pneumonia", "Shigella dysentriae", ”Propionibacterium acnes”, “Streptococcus sobrinus”, and “Pseudomonas aerugenosa”. The results of this review article show that ke tepeng china leaf extract is proven to have potential as an antibacterial agent which is characterized by the presence of an inhibition zone formed. The phytochemical content in Chinese ketepeng leaves such as flavonoids, saponins, tannins, alkaloids and phenols are thought to be antimicrobial. The difference in the diameter of the inhibition zone formed is influenced by the concentration of the extract, the type of solvent and the type of test microorganisms used. The types of solvents used are ethanol and methanol which are extracted by sonication and maceration.

Abstract

Hypertension is a risk factor that contributes to the development of stroke, heart failure, myocardial infarction and kidney failure. Even though in some cases the symptoms can be found, there are quite a few who think of it as just an ordinary disorder so they realize too late that hypertension is affected. This study aims to determine the effectiveness of giving honey in reducing blood pressure in elderly people with hypertension at the Theodora Makassar Nursing Home. This type of research is experimental with a cross-sectional design. The sampling technique was purposive sampling for 7 research subjects. Data was collected through primary data measuring blood pressure before and after administering forest honey with and/or without antihypertensive medication. The statistical test used is the paired T test. The results showed that the average systolic blood pressure before giving honey was 143.28 mmHg and after giving honey 134.14 mmHg. Then the diastolic blood pressure before honey was 82.14 mmHg and after honey 71.85 mmHg. The average systolic and diastolic blood pressure after administering honey was 134.14 mmHg and 71.85 mmHg. The statistical test results obtained a p-value of 0.018 for systolic blood pressure and a p-value of 0.011 for diastolic blood pressure (p<0.05). The conclusion is that giving honey is effective in reducing blood pressure in elderly people suffering from hypertension at the Theodora Makassar Nursing Home.

Abstract

One of the primary challenges in rice cultivation is the disturbance caused by pest infestations. Among the pests that frequently cause damage to rice plants is the white rice stem borer (Scirpophaga innotata). The life cycle of Scirpophaga innotata comprises egg, larva, pupa, and adult stages. This article is based on a literature review and discusses the natural enemies most commonly encountered at each stage of the Scirpophaga innotata life cycle. The findings of this article can be summarized as follows: Natural enemies of the white rice stem borer during the egg stage include parasitoids such as Trichogramma japonicum Ashm., Tetrastichus schoenobii, and Telenomus rowani, as well as the predator Conocephalus sp. During the larva-pupa stage, parasitoids such as Apantheles sp., Bracon sp., Tropobracon sp., and Temelucha bigutella are present, along with predators like Miscrapis crocea and Harmonia octomaculata. Regarding the adult stage, parasitoids were not found to be natural enemies of adult S. innotata. However, the most commonly encountered predators include Coccinella transversalis (Thunberg) and Paederus sp.
