Insects as one of the faunas in it is an interesting aspect to be studied, especially ants. The research was conducted in Nagari Gunung Selasih and Sungai Kambut, Pulau Punjung District, Dharmasraya Regency, West Sumatra from November 2017 to January 2018. This study aims to determine the diversity of ants in the palm oil plantation ecosystem bordering the forest ecosystem. This research takes the form of a survey where the Purposive Random Sampling method was used for points sampling. Hand Collecting, Bait Trap, and Pitfall Trap sampling methods were applied for each plant. Identification of the samples obtained was carried out at the Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. Total ants (Hymenoptera: Formicidae) collected during the study were 3,046 individuals consisting of 5 subfamilies, 15 genera, and 29 species. The most dominant species was Anoplolepis graciliphes, followed by Odontoponera denticulate and Odontomachus simillimus. Based on the results of the study, it can be concluded that the level of abundance and diversity of ant species is not directly affected by the distance from the forest ecosystem, but it is strongly influenced by the composition of environmental factors such as temperature, humidity, light intensity, altitude, and management of existing habitats and vegetation.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"382 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123390466","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 use of Ultisol for the cultivation of problematic plants with poor organic matter and nutrients needs to be overcome by giving organic matter. One of the potential sources of organic fertilizer in Kuantan singingi district is kirinyuh bush (Chromolaena odorata). This study has the objectives of 1) knowing the contribution of biomass and the distribution of kirinyuh. and 2) To determine the potential of kirinyuh as a source of organic fertilizer through the C, N, P and K nutrients it contains. This research is a field research that will be carried out using a survey method with purposive sampling. Kirinyuh's observation locations were in two sub-districts in Kuantan Singingi Regency, namely Kuantan Hulu Kuantan District and Mudik Kuantan Singingi Regency. The results of this study can be concluded that kirinyuh is widely available and easy to obtain in Kuantan singingi Regency and contains high nutrients so that it is very potential to be used as a source of organic fertilizer in the form of green manure. Kirinyuh weed in Kuantan singingi has not been utilized and is often found living in groups on the outskirts of land, roads, rice fields, shrubs and irrigation. Kirinyuh biomass as a source of organic matter varies, generally every 1m2 produces about 2-3 kg of biomass. The results of laboratory analysis, kirinyuh leaves contain nutrients of 42.95% C-organic, 4.41 %N, 1.032 %P and 3.05%K, while the stem contains 45.68% C-Organic.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114332682","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 purpose of this study was to analyze the botanical composition and potency of Kelakai growing on peatlands of Central Kalimantan as a medicinal plant. This research method was an exploratory method supported by laboratory experiments which aimed to determine its potential as a medicinal plant and wound epithelialization under controlled conditions. The data on the botanical composition of Kelakai were analyzed using descriptive analysis, where the sample was obtained by purposive random sampling, while the potency data was analyzed using the Oneway Anova test and then Duncan's 1% test was performed. The wound is on the abdomen 2 cm long. The treatment given was applying Kelakai extract gel with different concentrations on a regular basis every day for 3 days. The results showed that Kelakai on peat swamp land in Central Kalimantan was the most dominant, so it can be concluded that its botanical composition can be a source of forage. The nutritional content of the Kalakai swamp green is quite high, so the Kelakai leaf extract gel has proven potential and can be recommended as an effective wound healing drug at a concentration level of 35%, with the optimal concentration in wound healing at a concentration level of 40%.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126863264","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}
