Abstract

Mangrove communities grow well in the tropics and are able to adapt to extreme environments, such as: high temperature, high salinity, extreme tides, high sedimentation, and oxygen-poor growing substrate conditions. Information about mangrove ecology is very important to provide an overview of the current condition of mangroves. The aim of this research is to determine the structure of the mangrove community in Pare Mas Jerowaru, East Lombok. This research used a purposive sampling method and a combination of line and quadrat transects. The research results obtained 3 types of mangroves in Pare Mas waters. The diversity index value is in the low category and the dominance index value is medium to high. The species Rhizophora apiculata had the highest frequency value (0.57 ind/m²) and the lowest was Avicennia marina (0.10 ind/m²). Density at the tree level is in the sparse category, while at the pole, sapling and seedling level it is in the medium to very dense category. The types of mangroves that have the highest cover values in the tree, pole and stake categories are Sonneratia alba and Rhizophora apiculata. The highest INP values in the categories of trees, poles, saplings and seedlings were 272.99% (Sonneratia alba), 173.58% (Sonneratia alba), 215.51% (Rhizophora apiculata) and 200.00% (Rhizophora apiculata).

Abstract

The inguinal hernia is the subcutaneous part of the peritoneum containing the abdominal viscera that exits through the inguinal canal or directly through the abdominal wall. Most patients do not realize they have an inguinal hernia until swelling arises in the thigh fold area or pain in the groin area. The purpose of this literature review is to provide an update regarding the diagnosis and management of inguinal hernias. The diagnosis of an inguinal hernia is largely based on the history and physical examination, whereas imaging is rarely performed unless there is a certain suspicion. Surgical management can be performed on patients with symptoms, while asymptomatic patients can be subjected to conservative therapy.

Abstract

Sexually Transmitted Infections (STIs) are infections that are transmitted through sexual contact with an infected partner through vaginal, oral and anal sex. STIs can also be transmitted from mother to child during pregnancy, childbirth, and breastfeeding. LGBT is a group at high risk of contracting STIs, especially syphilis. Syphilis rates increased every year by 28.6% from 2020 to 2021. LGBT people accounted for 47% (18,381) of syphilis cases and (44%) LGBT people who had syphilis also had HIV. This article was written with the aim of finding out more about the molecular biology, phatophysiology and clinical symptoms of syphilis. The method used is a literature review on the NCBI website, Google Scholar, and Research Gate. It can be concluded that syphilis can be cured in the early stages of infection, but if adequate treatment is not received it can become a systemic infection and progress to the latent phase. Syphilis can also increase the risk of transmitting HIV which cannot be cured but can take medication to treat the symptoms. In conclusion, LGBT is a group at high risk of contracting STIs. The reason is, they have different sexual lives in general. The sexual activities carried out are anal sex, oral sex and variations thereof. Anal sex has a potential risk of injury to the anus. Because the anus is not elastic, sexual intercourse carries a risk of injury, so syphilis is more easily transmitted if there is damage to the anal area.

Abstract

Thin Cell Layer (TCL) is a plant propagation technique using thin explants (1-2 mm) through tissue culture. Callus induction is a crucial step in establishing plant regeneration. The type and concentration of growth regulators influence callus formation. 2.4 D is a growth regulator that is commonly used for callus induction in various plants. The research aims to determine the effectiveness of thin explants and 2,4-D in inducing Dendrobium discolor callus. The method used a Completely Randomized Design (CRD) with four treatments (1, 2, 3, and 4 mg/L). Adding 1, 2, and 3 mg/L 2,4-D can induce 100% calluses through the TCL explant. The callus has a friable to compact texture. The result showed that 2 mg/L 2,4-D was the best concentration for callus induction of D. discolor through TCL technique, indicating the greenish color, friable texture, and meristematic tissue.

Abstract

Pneumonia coinfection in COVID-19 patients can be an important risk factor for patient mortality. Red blood cell distribution width (RDW) is a predictor that can determine clinical outcomes in patients with respiratory tract infections and serious illnesses, so researchers want to conduct research to determine the difference in RDW values in COVID-19 patients with and without pneumonia at RSUM and RSUDP NTB. The design of this research is cross sectional. The sampling technique used was consecutive sampling. There were 110 COVID-19 patient data used in this research. Data collection uses medical record notes. The statistical analysis used was the Mann-Whitney test. The average age of patients was 48 years ± 16 years. Most of the subjects were male (53.6%). The most common comorbidity was diabetes mellitus (21.8%). The average RDW values in COVID-19 patients with and without pneumonia were 13.9% and 13.1%. The difference in the mean RDW value in the two groups is 0.8%. This study found that clinically there were differences in the RDW values of COVID-19 patients with pneumonia and without pneumonia at RSUM and RSUDP NTB.

Abstract

Harvesting gastropods and other intertidal biota during lowest tides called Madak, is a traditional activity of coastal community on the Lombok Island. The Madak tradition has the potential to be used as a biology learning resource in schools. Variations in the size of Gastropods can be used as a source of studying population ecology. The present study aimed to describe quantitatively Gastropoda populations harvested during the madak. This study was carried out by collecting snail Turbo setosus and Strombus labiatus shells harvested in the intertidal area of ​​Serinting Beach. Convenience sampling was applied to collect data from 5 people in 5 days. There were 120 individuals of T. setosus and 240 individuals of S. labiatus collected from 25 rads with varying shell sizes. The shell size of T. setosus ranges from 3.32 to 7.19 cm, which is then divided into 8 classes. The average size of the harvested shells was 5.08 cm with a standard deviation of 1.96 cm, which means that the distribution of the data obtained was less varied. The size of S. labiatus shells ranges from 2.40-4.78 cm which is then divided into 9 classes. The average size of harvested shells was 3.48cm with a standard deviation of 0.92 cm, which means that the distribution of the data obtained is less varied. The population structures of T. setosus and S. labiatus harvested were less diverse, so further research is needed to determine the population structure of T. setosus and S. labiatus found in nature.

Abstract

The intertidal area is utilized by coastal communities to collect intertidal biota during low tides, which is called “madak. Madak culture is also practiced by the people of Sumbawa. One of the groups of animals taken during madak are Gastropods and Bivalves from the Phylum Mollusca. Gastropods and Bivalves have many benefits for coastal communities. One of the direct benefits of Gastropods and Bivalves for society is consumption. This research focuses on the diversity that leads to the taxonomy of Gastropods and Bivalves caught by fishmen in the intertidal zone of Serinting Beach.The present study aims to analyze the diversity of Gastropods and Bivalves harvested during madak, to develop identification keys for harvested Gastropods and Bivalves, and to identify the amount of exploitation of Gastropods and Bivalves in madak. This study used a descriptive method of quantitative approach by purchasing Gastropods and Bivalves harvested by 5 madak-women in 5 days convenience (convenience sampling) The results found 5 orders, 11 families, and 28 species from 715 individuals of Gastropoda, while 2 orders, 3 families, and 4 species from 69 individuals of Bivalvia. Madak Gastropods and bivalves were used to develop identification keys. It was estimated that the number of Gastropods exploited was 3.348,4 individuals and bivalves were 351,6 individuals 1 per month.
