Bagworms, a major pest affecting oil palm plants, cause significant harm to leaves and decrease plant productivity. These caterpillars can rapidly reproduce and spread extensively if not effectively managed. Sipermetrin and Dimehipo are two types of insecticides utilized to combat bagworm pests on oil palm plants. This study employs a descriptive analysis approach, involving the collection of primary data through field observations and pest censuses, as well as secondary data from previous pest censuses within the company. Data collection was conducted meticulously to ensure precision and relevance to actual field conditions. The objective of this study is to assess the extent of bagworm pest infestation and evaluate the efficacy of Sipermetrin and Dimehipo insecticides in controlling these pests on oil palm plants at PT Plantations in Umada Pernantian \"A\", Marbau sub-district, North Labuhan Batu Regency. The findings of the study revealed that the application of Sipermetrin was more successful in managing bagworm pests compared to Dimehipo. The mortality rate of bagworm pests with Sipermetrin usage ranged from 80-90%, while with Dimehipo, it only reached 40-50%. Therefore, Sipermetrin has demonstrated greater efficiency in controlling bagworm populations and preserving the health of oil palm plants, offering a superior solution to the pest issue in these plantations.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"30 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141802541","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}

However, when natural disasters occur, or transportation disruptions happen from the sources of onion production, the price of shallots in the market increases. To reduce Riau companies' dependency on this raw material, it is necessary to develop shallot plants using optimal cultivation techniques to maximize growth and production. This research was conducted at the Experimental Garden of the Faculty of Agriculture, Pasir Pengaraian University, Rokan Hulu Regency, for three months from May 2022 to July 2022. The research utilized a completely randomized factorial design with two factors. The first factor involved the application of Vermicompost Fertilizer, with four treatment levels: 0. 200. 400. and 600 g/plot. The second factor involved the application of NPK 16.16.16 fertilizer with four treatment levels: 0. 10. 20. and 30 g/plot. The parameters observed included plant height, harvest age, number of tubers per cluster, tuber weight per bulb, wet tuber weight per cluster, dry tuber weight, and percentage of tuber weight loss. The research results indicated that the interaction between vermicompost fertilizer and NPK 16.16.16 fertilizer had a significant impact on plant height, harvest age, number of tubers per cluster, number of tubers per tuber, wet tuber weight per cluster, and dry tuber weight per cluster. The best treatment was a combination of Vermicompost 600 g/plot and NPK 16.16.16 30 g/plot. The main effect of the Vermicompost Fertilizer application was significant for all observation parameters, and the main effect of NPK 16.16.16 also had a significant impact on all observation parameters.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"29 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140513088","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}
