Abstract

Diversity in animals is a variation of the structure, shape, number, and other properties at a particular time and place. Diversity describes a situation that varies from one person to another, objects that occur cause differences in size, shape, texture, and amount. Arthropods are animals with segmented legs, and segments on the body belong to the animals that live both above and below the ground. This research aims to know the diversity and types of ground surface arthropods in the forest surrounding the Department of Biology, Faculty of Mathematics and Natural Science, Manado State University. This research is located in the forest area of the Department of Biology, Faculty of Mathematics and Natural Science, Universitas Negeri Manado, Tonsaru village, South Tondano District, Minahasa Regency, North Sulawesi. Taking data using the pitfall trap method and analyzing using Shannon Wiener diversity index, species richness index, species evenness index, and species dominance. The data collection and collection results obtained as many as 12 genera with a total of 166 individuals. Namely, Myrmica, Carebara, Paraponera, Papederinae, Anisolabis, Hogna, Spirostreptus, Cafius, Phalangium, Opilio, Oxidus, and Pholidoptera. The diversity index value yields 1,11043. The species richness index shows a value of 2,1518. Index the evenness of the species showed a value of 0,44687. The dominance of type indicates a value of 0,457. The level of diversity is moderate, species richness is low, evenness is moderate, and species dominance is low.

Abstract

The diversity of gastropod species is influenced by different substrates, environmental conditions, and human activities, so it is necessary to research the diversity of gastropod species in Lake Tondano. This study aims to obtain data on the diversity of gastropod species that live around Lake Tondano. The study was conducted in May 2022. The collection of research data on the diversity of gastropods in Lake Tondano begins by dividing the research area into five stations. Each station forms a Line transect of about 50 meters x 10 meters. At each line transect, 10 points will be determined in a zigzag manner for observation and sampling. The determination of the sample is carried out by purposive sampling. The gastropod samples will be identified and then documented, and the number will be recorded. Gastropods found around Lake Tondano are Achatinidae (Achatina fulica), Station 1: -, Station 2: -, Station 3: 1, Station 4: 1, Station 5: 1. Ampullariidae (Pila Ampullacea), Station 1 :173, Station 2 : -, Station 3: 73, Station 4: 117, Station 5: 57. Potamididae (Tylomeliana toradjarum), Station 1: 321, Station 2:2, Station 3: 123, Station 4: 3, Station 5 :-. Viviparidae (F. Javanica/ Filopaludina Javanica), Station 1: 85, Station 2: 161, Station 3: 335, Station 4: 315, Station 5: 153. Based on these data, the highest index is at point 3, and the density index is at point 1.

Abstract

Avocado (Persea americana Mill) is a fruit plant that has high nutritional value and is relatively economical. Efforts to increase the production of avocado seeds (Persea americana Mill) are still often constrained by pests and diseases. This study aims to determine the types of insects associated with avocado seeds (Persea americana Mill) and the level of damage to avocado seeds (Persea americana Mill) due to insect pests in Seeds Garden of the Melati Women Farmer Group 2, Ranowulu District, Bitung City. This study used a survey method, namely direct observation (visual) of pests that attack avocado seeds (Persea americana Mill). This research is a descriptive research with survey method. Observation activities by direct observation on avocado plant seeds (Persea americana Mill). Insects were identified using an insect identification book guide. The results of identification and direct observation at the Seeds Garden of the Melati Women Farmers Group 2, Ranowulu District, Bitung City, found 3 orders consisting of 4 insects, namely the Ordo Orthoptera Wood Grasshopper (Valanga nigricornis) and Green Steamed Grasshopper (Atractomorpha crenulata), Ordo Homoptera White Dompolan Tick (Planococcus citri), Ordo Hemiptera Bapak Pucung (Dysdercus cingulatus). The results showed that the percentage of seeds attacked by insect pests in the Seeds Garden of the Melati Women Farmer Group 2, Ranowulu District, Bitung City with a seedling age of 1-10 months was 36.66% and a damage rate of 26.97% of the total seeds of the 30 seeds that had been observed and included in the moderately damaged category.

Abstract

Rabbits are livestock that has the potential to provide meat in a relatively short time, so people's consumption of animal protein is expected to be fulfilled. Market vegetable waste can also be used as feed, especially for rabbits. When processed into rabbit feed, waste is not only a product, but from the feed consumed by rabbits, it can produce meat of good quality. This study aimed to determine whether feeding vegetable waste can increase rabbit body weight and whether combining pellets and vegetable waste can increase rabbit body weight. This study used a quantitative experimental method using an experimental design that was Completely Randomized Design (CRD) with six treatments and four replications. The survey results showed that feeding vegetable waste was effective as feed for rabbits because it could increase the body weight of rabbits (Oryctolagus Cuniculus L.). The more balanced the market vegetable waste feed in the form of cabbage, carrots, pattern (young corn shoots) and pellets were given, the higher the weight gain of rabbits (Oryctolagus Cuniculus L.). Market vegetable waste is not recommended as a good feed. Still, it can be used as a supplement only because research results show that market vegetable waste does not have a significant effect.

Abstract

Aedes sp. is a species of mosquito that acts as a vector for transmitting dengue. The use of chemical insecticides to control Aedes sp. result in negative impacts on the environment. One vector control of dengue fever is using plant-derived insecticides, namely stolon Alang-Alang extract Imperata cylindrica L. which is known to be more effective against dengue fever mosquitoes Aedes sp. This study aims to determine the effectiveness of stolon alang-alang extract against the mortality of dengue mosquito larvae in Aedes sp. The method in this study is to analyze mortality data using Microsoft Excel 2016 probit analysis using seven treatments and three replications with a concentration of 0.2%, 0.25%, 0.3%, 0.35%, 0.4%, 0.45%, and 0.5%. Larvae were tested at each concentration of as many as ten tails. The effectiveness of stolon alang-alang extract on larval mortality was observed every 12-72 hours. The data were analyzed by calculating the LC50 value using probit analysis. The results showed that alang-alang stolon extract effectively killed the mosquito larvae of Aedes sp. ranging from 0.25-0.5% concentration. The highest mortality rate was obtained at a concentration of 0.3-0.5%, capable of killing 100% of the mosquito larvae of Aedes sp. A concentration of 0.3-0.35% can cause 100% mortality of larvae at 60 hours after application (JSA), a concentration of 0.4% can cause 100% mortality in 48 (JSA) and a concentration of 0.45-0.5% causes 100% mortality of larvae in 36 (JSA). Probit analysis showed the LC50 result was 0.2116% (2115.5 ppm) with a toxic category (500-5000 ppm).
