Abstract

People use the lacum plant (Cayratia trifolia L.), an herbaceous plant from the Vitaceae family that grows wild, as a traditional medicine. Lacum leaves have special things inside them called secondary metabolites like flavonoids, alkaloids, phenols, steroids, terpenoids, and tannins. Toxicity tests must be carried out because flavonoids, alkaloids and steroids have harmful effects on test animals at certain concentrations. A substance or natural ingredient that will be used as a medicine is tested to determine its level of toxicity. The purpose of this study was to determine the total levels of toxic compounds and the level of toxicity in the ethanol extract of lacum leaves (Cayratia trifolia L.) Brine Shrimp Lethality Test (BSLT). This research uses Artemia salina leach larvae as test subjects. This research also used an experimental approach arranged in a completely randomized design (CRD) consisting of 7 treatments and 4 replications. The percentage of larval death was used in probit analysis to identify the toxic effects of the extract and calculate the LC50 value. Based on the research results, it shows that there are total levels of toxic compounds in the ethanol extract of lacum leaves (Cayratia trifolia L.), namely flavonoids, alkaloids and steroids with an LC50 value of 105.08 ppm which places it in the moderately toxic category and is thought to have anticancer properties.

Abstract

Cermin Beach is one of the beaches that has an abundant level of diversity and abundance of biota, one of which is the level of diversity of gastropods which have many roles as key organizations in food networks in waters. Gastropods as organisms that live in waters are very sensitive to changes in the water quality where they live. This research was conducted on November 25 2023 with the aim of knowing the types of Gastropods found at Cermin Beach, Paya Dua Village, Peudawa District and to determine the structure of the Gastropod community related to individual density, relative abundance, frequency of presence, diversity, evenness, and similarity of species by applying a survey method with primary data collection carried out using the Line Transet method, namely by walking along the intertidal zone along the specified transect line. The results show that at Cermin Beach in Paya Dua Village, Peudawa District, 46 species of gastropods were found with different numbers at each station. The relationship between physical and chemical factors in Cermin Beach waters also influences the diversity of Gastopoda.

Abstract

Sugarcane is a type of grass plant that is widely cultivated by the community and has a fairly high nutritional content. Sugarcane juice contains sucrose which consists of glucose and fructose. Sucrose contained in sugarcane juice serves as a source of energy for spermatozoa. This study aims to determine the effect of adding sugarcane juice to skim milk diluent and egg yolk on motility, viability and semen abnormalities of Simmental cattle. This research was conducted at the UPT Artificial Insemination Department of Food Security and Animal Husbandry of North Sumatra Province. The method used in this study was a completely randomized design with 5 treatments and 4 replications consisting of P0: Skimmed milk and egg yolk diluent without sugarcane juice, P1: Skim milk and egg yolk diluent + 25 ml of sugarcane juice, P2: Milk diluent skim and egg yolk + 35 ml of sugarcane juice, P3: Diluent of skim milk and egg yolk + 45 ml of sugarcane juice. Parameters measured were motility, viability and sperm abnormalities of Simmental cattle semen. The results of this study indicate that the P1 treatment with 25 ml of sugarcane juice was able to maintain motility during 72 hours of storage by 40%, the highest mean value of spermatozoa viability during 144 hours of storage (60.90% ± 1.08), and the lowest spermatozoa abnormality value during storage 144 hours (17.10% ± 1.08). The conclusion of this study was that 25 ml of sugarcane juice in skimmed milk and egg yolk diluent could maintain the quality of Simmental cattle spermatozoa.

Abstract

There are differences on the surface of red blood cell membranes in the types of carbohydrates and proteins that make a person's blood unique, known as blood types. Blood grouping using the ABO system is determined by the absence of antigen A or antigen B in the blood. The presence of A antibodies or B antibodies in red blood cells and serum/plasma. This research was conducted at the Biology Education Research Program, FKIP, Samudra University. This research was conducted from 14 to 24 November 2023. This type of research was qualitative with the slide test method. The parameters observed were the types of blood groups in various samples of 30 students. The results of this study showed that there were more O+ blood types compared to the others, O+ got 46.6% while the others, such as blood type A, were only 16.6% of 30 samples, blood group B was only 33.3% of 30 samples and the last one was the highest. The small number, namely blood type AB+, only reached 3.33% of 30 samples.

Abstract

Kelulut (Hymenoptera: Meliponini) is a honey-producing bee and belongs to the eusocial bee group. Kelulut is also a pollinating insect that is widespread in the world, including Indonesia. The study of kelulut diversity can describe the composition of kelulut in an area and the condition of an ecosystem. This study aimed to obtain data and information on kelulut diversity in three different forest areas (primary forest, secondary forest, and ecosystem restoration area). The study was conducted by capturing kelulut using sugar solution bait traps and free sampling. The results obtained were analyzed using the Shannon-Wiener Diversity Index (H'), the Evenness index (E) and the Simpson Dominance Index (C). A total of 747 individuals from 12 types of kelulut were found in this study. The secondary forest gets the highest H' value (1.869), followed by the primary forest (1.672) and ecosystem restoration area (1.159). The diversity of stingless bees is higher in forested areas due to environmental factors such as temperatures within the normal range (25.5-28.9°C), the availability of trees for nesting, and the abundance of food sources from flowers.

Abstract

Consuming balanced nutritious food with macronutrient content including carbohydrates, protein and fat for pregnant and breastfeeding mothers as well as children under five during the growth and development period is one of the efforts to prevent and treat anti-stunting, up to the age of 2 years. Waters and beaches are one of the habitats for marine biota such as bivalve shells, gastropods, various fish and other marine biota whose names and uses are not yet popular but are widely consumed by coastal communities, including Sipunculus nudus. Marine biota from the phylum Sipuncula in some areas are called sea worms, are one of the marine biota whose habitat is in the sand, and are the favorite food of coastal communities. Information about the nutritional and mineral content of this marine biota species has not been widely reported. This research aims to determine the macronutrient content of Sipunculus nudus collected from the coastal waters of Samboang, South Sulawesi. Determination of macronutrients was carried out using several methods, including for protein using the Kjeldahl method, fat using extraction with n-hexane solvent, water and ash content using an oven and furnace. The results of measuring the macronutrient content of Sipunculus nudus showed a water content of 72%, ash content of 1.19%, protein content of 6.5%, fat content of 2.07% and carbohydrate content using difference calculations was obtained at 18.24%.

Abstract

Coconut crabs (Birgus latro) is a fishery resource that is only found in eastern Indonesia, and the waters of Ternate City are an area that has this potential.  This research aims to determine the size distribution and habitat characteristics of coconut crabs in Tomajiko, Hiri Island District. The data collection method consists of several stages, namely determining stations, distributing bait, catching coconut crabs, morphometric measurements, and observing environmental parameters. Determination of stations in this study was carried out based on topographic differences in Tomajiko (divided into two stations). Coconut crab catching uses the roaming survey method. The bait used is coconut meat that has been split into several parts and coconut meat that has been mashed. The morphometric dimensions measured were chest length (carapace length) and body weight. The habitat characteristics observed were the type and extent of vegetation, organic matter content and substrate texture, environmental parameter measurements (soil temperature, air humidity and soil pH). The results of the research showed that the coconut crabs caught at both stations had relatively the same length, but the largest weight was found at station 2. Habitat characteristics in Tomajiko, Hiri Island strongly support the survival of coconut crabs.
