Abstract

Pregnant women must undergo routine check-ups in a check-up package called Antenatal Care (ANC). One of the ANC service packages that pregnant women must follow is the Triple Elimination screening examination which can prevent 3 infectious diseases, namely Human Immunodeficiency Virus (HIV), hepatitis B, and syphilis which can be transmitted from mother to fetus. The purpose of this study was to determine the relationship between knowledge of pregnant women, husband's support and attitudes of pregnant women with the Triple Elimination screening examination in the working area of ​​the Cakranegara Health Center. cross-sectional research using quantitative methods. Simple random sampling is the method used for sampling.  The Cakranegara Community Health Center served as the site of the study. There were 110 responders in the research sample. The Chi-Square test was used to evaluate the data, and a significant result of p < 0.05 was found. Among the 110 pregnant women who responded, 58.2% had high knowledge (p-value = 0.011), 50.9% had positive husband support (p-value = 1.000), and 73.6% had positive attitudes (p-value = 0.001) among those who responded about pregnant women's attitudes. While there is a correlation between pregnant women's attitudes and their level of knowledge regarding the Triple Elimination screening examination at the Cakranegara Community Health Center, there is no significant correlation between husband support and the test.

Abstract

The prolactin gene (PRL) in chickens is one of the genes that regulates broodiness and egg production in laying hens. Single Nucleotide Polymorphism (SNP) is a form of single nucleotide variation in the DNA base sequence at specific locations in the genome that can influence differences in quantitative traits in livestock. This study aimed to identify SNPs in the prolactin gene of native chickens. The research methods included DNA extraction, PCR amplification, and DNA sequence analysis for genotype determination of individuals. The results revealed four mutation points at positions g.8052 bp T>C, g.7886 T>A, g.7823 A>G, and g.8069 T>C. All mutation points in exon 5 were substitution mutations. Statistical analysis showed that all loci were polymorphic and the population was in Hardy–Weinberg equilibrium.

Abstract

Indonesia is the largest archipelagic country in the world, with extensive coastal and oceanic areas and a high diversity of marine biodiversity. The coastal regions of Indonesia serve as habitats for various types of marine animals that possess both beauty and potential dangers, particularly from marine animal stings. In addition to marine animal stings, decompression sickness also poses a serious emergency in the maritime context. The purpose of this article is to provide new insights into the importance of understanding and recognizing decompression syndrome, as well as the bites and stings caused by marine animals, as early indicators of emergencies in the maritime field. This understanding can enhance early detection, appropriate treatment, and awareness of complications arising from maritime emergencies. The article will focus on marine animals such as the blue-ringed octopus, sea urchins, pufferfish, lionfish, jellyfish, stingrays, and stonefish, which are associated with emergencies in the maritime field. Data sources were gathered through electronic searches on library databases including Google Scholar, ProQuest, MDPI, and PubMed to find articles discussing "emergencies in the maritime field.".

Abstract

Frigate tuna (Auxis thazard) is a pelagic and neritic fish resource that has economic value. Fish diet is one of the important information in monitoring the sustainability of fisheries resources in the future. This study aims to determine the composition of food and determine the Index of Preponderance of frigate tuna caught by fishermen in West Sumatra waters. The method used in this study was random sampling by taking 98 samples of frigate tuna obtained from the catch of fishermen in West Sumatra waters landed at the Air Bangis Fish Landing Center, West Pasaman Regency, and Gaung Fish Auction Site, Padang. The analysis used the Index of Preponderance to determine the main food, additional food, and complementary food. The results showed the composition of food in the stomach of frigate tuna consisted of 3 groups of organisms, namely zooplankton (61.04%), phytoplankton (31.82%), and pisces (7.13%). The main food of frigate tuna is zooplankton (62.10%), while the additional food are phytoplankton (27.73%), and pisces (10.16%). The availability of frigate tuna food in West Sumatra waters supports the sustainability of the frigate tuna population in these waters.

Abstract

Dryland agriculture continues to face numerous challenges that need resolution. Maize has emerged as an alternative food source, with additional uses as animal feed and biofuel. However, maize cultivation in the drylands of West Nusa Tenggara has yet to fully apply agronomic principles, resulting in suboptimal yields. This literature review evaluates key agronomic factors affecting maize productivity in West Nusa Tenggara’s drylands. The most suitable and marginally suitable land for maize among the three regencies was found in East Lombok, with soil pH (H2O) ranging from 5.8 to 7.4 (slightly acidic to neutral), total nitrogen (N) between 0.09–0.19% (low to moderate), available phosphorus (P) between 14.4–54.76 ppm (high to very high), and organic carbon (C) ranging from 0.4–0.8% (low). Soil texture includes sand (62.67–76.00%), silt (20.13–30.79%), and clay (2.59–11.71%), indicating a sandy loam to loamy sand composition. Seed varieties used in East Lombok include Bima 20 URI, Nasa-29, JH-37, Bima-14 Batara, JH 27, and HJ 21; West Sumbawa uses Bisi 18 and Jakarin; while North Lombok uses Gumarang, Lamuru, and NK 212. Traditional water conservation techniques are practiced in East Lombok and West Sumbawa, while sprinkler irrigation is employed in North Lombok. Fertilizers, including Trichocompost, Phonska, Urea, and rice husk biochar, are applied across East Lombok, North Lombok, and West Sumbawa. Integrated pest management (IPM) is applied in East Lombok and North Lombok to control fall armyworm (Spodoptera frugiperda) using refugia plants, and in West Sumbawa, microcontroller technology is used to manage monkey pests.
