Abstract

The mangrove ecosystem is inhabited by various macroinvertebrates, such as brachyuran crabs, hermit crabs, gastropods, and bivalves. The mangrove ecosystem is a primary habitat for crabs to grow and develop, and it serves as a nursery ground for young organisms before they reach adulthood. This research was conducted from September 2023 to June 2024 in Gili Sulat, East Lombok. The aim of this study is to determine the diversity of crabs in Gili Sulat and their association with mangrove species. The method used in this research is purposive sampling, taking into account the density of mangroves.The study found 12 mangrove species: Rhizophora mucronata, Rhizophora stylosa, Rhizophora apiculata, Ceriops tagal, Excoecaria agallocha, Bruguiera gymnorrhiza, Pemphis acidula, Avicennia marina, Lumnitzera racemosa, Xylocarpus rumphii, Cordia subcordata, and Osbornia octodonta. The mangrove density at station 1 was 1800 ind/ha, at station 2 was 1222 ind/ha, and at station 3 was 2411 ind/ha. The crabs found included 3 species: Baptozius vinosus, Notonyx sp, and Portunus pelagicus. The abundance of crabs at station 1 was 55.6 ind/ha, at station 2 was 33.3 ind/ha, and at station 3 was 66.7 ind/ha. The correlation between mangrove density and crab abundance had a coefficient of determination of 91.6%, indicating that mangrove density can significantly influence crab abundance. There is one species of crab that has a positive association with one species of mangrove, namely the crab species Baptozius vinosus and the mangrove species Rhizophora mucronata.

Abstract

Polycystic ovary syndrome (PCOS) is a common reproductive endocrine hormone disorder in women of childbearing age with a global incidence of 8-13%. The use of medical drugs in the long term can cause serious side effects so that the utilization of curcumin contained in Curcuma longa can be an alternative therapy consideration for PCOS. This paper will discuss the potential and benefits of curcumin content as an alternative therapy for PCOS. The method used, namely by reviewing the literature in national and international journals that are in accordance with the objectives of the review. The results of the literature review show that curcumin has effectiveness in treating PCOS through various mechanisms of action accompanied by minimal side effects. Alternative therapy of PCOS by taking curcumin needs to consider the dose, duration of use, and further research with larger subjects in assessing its effectiveness and side effects. However, it is suspected that nanocurcumin formulations have higher bioavailability and solubility than free curcumin, giving it even greater potential in the treatment of PCOS in the future. In conclusion, curcumin has the potential as an alternative therapy for PCOS that requires further research to achieve the optimization of PCOS treatment in the future.

Abstract

Celery (Apium graveolens L.) is a vegetable that has many health benefits because it contains nutrients and antioxidants that makes it popular among the public, but its production is relatively low. One way to improve the quality and quantity of celery plants is to provide liquid organic fertilizer (LOF) of banana peel and coconut water which contains essential nutrients such as calcium, phosphorus, nitrogen, potassium, magnesium, sodium, sulfur, sugar, protein, and two hormones. namely cytokinins and auxins which are needed in the growth of the plant. The study aims to analyze the growth response of celery plants given liquid organic fertilizer (LOF) from banana peel and coconut water. The type of research is an experiment with a complete randomized design (CRD) consisting of 7 treatments, namely (P0 = Control, P1 = 10% banana peel, P2 = 15% banana peel, P3 = 20% banana peel, P4 = 10% coconut water, P5 = 15% coconut water, and P6 = 20% coconut water), each treatment is repeated 6 times with a total sample of 42. The observed variables were plant height, number of leaves, and number of tillers measured at 6 WAP, 8 WAP, 10 WAP, and 12 WAP. Data analysis used ANOVA followed by a 5% significant BNT test with the help of the SPPS 25 program. The results of the research showed that the best growth was at the age of 12 WAP with a concentration of 20% organic fertilizer and banana waste organic fertilizer was more effective than coconut water in increasing the response of celery plant growth.

Abstract

Carp is a valuable freshwater fish that thrives in various temperatures and water conditions, making it suitable for cultivation in diverse regions to satisfy community needs for animal protein. However, one of the primary challenges in carp farming is the high cost of commercial feed, which can contribute up to 91.2% of total production expenses. Thus, identifying affordable alternative protein sources is essential. Indigofera zollingeriana, a protein- and amino acid-rich plant, shows potential as an alternative to traditional feed ingredients like soybean meal. This study examines the effectiveness of using Indigofera as a feed ingredient for Sinyonya carp (Cyprinus carpio). The research applied a Completely Randomized Design with 5 treatment groups, each with varying Indigofera zollingeriana concentrations: TDI 0, TDI 25, TDI 50, TDI 75, and TDI 100. Findings revealed that Indigofera-based feed significantly boosted absolute growth and daily growth rate of the fish, although it did not influence feed efficiency or survival rate. The optimal concentration was determined to be TDI 75, or 75% Indigofera. Water quality remained favorable for the fish throughout the study.

Abstract

Necrotizing Enterocolitis (NEC) or intestinal inflammation is a gastrointestinal disease that is the leading cause of death among infants. NEC is often diagnosed late due to its non-specific signs and symptoms, resulting in increased mortality and morbidity. The purpose of this paper is to explain the mechanisms of how synbiotics, probiotics, and prebiotics contribute to the prevention of NEC. Several randomized trials and observational studies have identified various factors associated with NEC. However, the causality of many of these factors remains unclear and may involve different etiological mechanisms. Prevention of NEC can be achieved through the administration of synbiotics, probiotics, and prebiotics. According to previous research, the administration of synbiotics, probiotics, and prebiotics has significant potential and benefits in preventing NEC. The data sources were obtained by conducting an online search through library databases, including PubMed, ProQuest, ScienceDirect, MDPI, and Google Scholar. According to previous research, the administration of synbiotics, probiotics, and prebiotics has significant potential and benefits in preventing NEC. This paper summarizes the current  etiology, risk factors and synbiotics, probiotics, and prebiotics Prevention of Necrotizing Enterocolitis.
