Pest control is done by utilizing natural enemies, such as ants by being stimulated with artificial food. This study aims to observe the population of dominant species and the effect of various artificial feeding treatments on ants that act as predators or pollinators in chili plants. The study was arranged in a Randomized Group Design (RGD) with 5 treatments, namely P0: Control (no pellet or sugar solution treatment); P1: 10 g artificial feed pellets; P2: 10% sugar solution; P3: 10% sugar solution and 10 g artificial feed pellets; and P4: 10 g artificial feed pellets (put into artificial nest) which was repeated 4 times. Observations were made five times at three-day intervals. Data were analyzed by calculating the species diversity index (H'), species dominance index (C), and ant population. Based on the results, the ant diversity index in this experiment was classified as moderate at 1.17 (H' 1.0-3.0) and the ant dominance index was 0.35 (low: C<0.5). Ant identification revealed four species from three sub-families: Myrmicinae, Dolichodorinae, and Formicinae, namely Pheidole sp., Monomorium sp., Tapinoma sp., and Paratrechina sp. While species that have the potential as predators or pollinators on chili plants are Tapinoma sp.. Artificial feeding with treatment P3 (10 g artificial feed and 10% sugar solution) can have an effect and increase the population of Tapinoma sp. ants with an average of 81.95 heads on chili plants.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133229187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sampling of feed ingredients and 20 eggs was carried out on each farm for analysis in the laboratory. The descriptive analysis was performed on acquired data. The results showed that farmers in East Lombok used different percentages of corn, concentrate and mineral feed ingredients. The nutritional content of feed given consist of crude protein (14,17-16,90%), crude fat (3,17-3,36%), crude fiber (6,13-7,06%), calcium (1, 03-1,29), phosphorus (0,26-1,33%) and metabolic energy (2751,96-2925,79 Kcal/kg).

One example of physiological and anatomical adaptation is the relationship between transpiration rate and number of stomata. Therefore, it is necessary to conduct research on the relationship between transpiration rate and number of stomata in Rhoeo discolor plants at the University of Veteran Bangun Nusantara campus. Measurement of the rate of transpiration used Clobat Clorite paper and counted the number of stomata by making an incision in the lower epidermis of the leaf. Data analysis on the relationship between transpiration rate and number of stomata used prodact moment and qualitative descriptive to determine differences in transpiration rate and number of stomata in Rhoeo discolor leaves. From the research results it can be concluded; There is a relationship between the speed of transpiration and the number of stomata of the Adam Hawa plant (Rhoeo discolor) on the campus of the University of Veterans Bangun Nusantara, but the relationship is very small (r = 0.298). Discolor rhoeo plants that are in dry, dry shaded, and humid environments have different transpiration rates and number of stomata. Anatomically and physiologically the Rhoeo discolor plant can be used as a source of learning and an ornamental plant so that this plant needs to be cultivated and planted in more locations within the Veteran Bangun Nusantara University campus.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115790078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Rote turtle is unique in its long neck and snake-like head. Rote turtles are rarely found in their natural habitat because many are hunted to be traded by collectors of endemic reptiles. The purpose of this study was to determine the effect of the habitat and behavior of the rote tortoise on its morphology and body mechanisms. The method used to compile this paper is to use literature reviews and literature studies from various sources to discuss 5 topics of study, namely: Rote Turtle Habitat, Rote Turtle Morphology, Blood Circulation System, Rote Turtle Respiratory System, Osmoregulation and Excretion of the Rote Turtle, and Uniqueness and Management of the Rote Turtle. Based on the results obtained, the habitat of the Rote turtle greatly influences the morphology and mechanisms of blood, respiration, osmoregulation, and excretion of the Rote turtle. The habitat for tortoise rote is the appropriate physical environment. Low rainfall of around 800-1200 mm/year and swamp grass with a height of about 2-3 meters. Potential predators for food and hunting have caused the Rote tortoise to become rare and rarely found in its natural habitat. The NTT government has designated three natural habitat lakes are natural habitats and the Governor of NTT Decree Number: 204/KEP/HK/2019 made the rote turtle habitat for the rote turtle Essential Ecosystem Area.","PeriodicalId":382423,"journal":{"name":"Jurnal Biologi Tropis","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114224965","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
