Generally, farmers use synthetic herbicides to control weeds. One way to reduce the use of synthetic herbicides is by using kiambang extract bioherbicides which are applied to weeds. Currently, there is no research to determine the effect of kiambang extract on upland rice germination. The purpose of this study was to assess the effect of kiambang bioherbicide on the germination phase of upland rice by giving several concentrations of kiambang bioherbicide. This study used a completely randomized design (CRD) with 5 concentration treatments, namely 2,4-D herbicide, 20%, 40%, 60%, and 80% bioherbicide.

Empty fruit bunches from the processing of Crude Palm Oil Factories and fronds of palm oil (TM) plants have the potential to be used as organic fertilizer. Composting without a decomposer takes a long time of seven months, so a bio activator is needed to speed up the process. Research with the aim of determining the influence of various bio activators in accelerating the composting of palm fronds and empty bunches has been carried out at PT. Bahana Karya Semesta unit of Sungai Air Jernih Estate, Pauh, Sarolangun, Jambi in November 2021-February 2022. The Research method used was a Complete Randomized Design (RAL) with two factors. The first factor is bioactivator consisting of four types such as LCPKS (liquid waste from crude palm oil factory), MOL (Local microorganism), EM4 (Effective microorganism 4) and cow dung. The second one is the compost material consisting of empty fruit bunch/EFB (5 kg), fronds (5 kg), EFB + fronds (2.5 kg + 2.5 kg), EFB + fronds + LCC (legume cover crop) (2 kg + 2kg + 1kg). C/N ratio, temperature, campiness, shrinkage, crumbly, and color of compost were also recorded. The results showed that the bio activator could decompose organic material with some of the parameters that we measured. The analysis of the C/N ratio showed that each treatment gave different results. Palm fronds + LCPKS had the highest C/N ratio of 91, meanwhile, the combination of EFB+cow dung showed the lowest C/N ratio of 23. The material of EFB + fronds + LCC showed the highest pH value of 6.36 and the highest compost depreciation of 57.48%. The variety of compost material has the same influence on the temperature, campiness, and color of the compost.

The goal of this study was to ascertain how different vegetable insecticide kinds interacted with treatment intervals to control fruit fly pests and curly red chili plant production. This study employed a two-factor, entirely randomized design. The first factor was a combination of four different doses of pesticides, including isoprocarb 2 g/l, betel leaf extract 100 cc/l, neem leaf extract 100 cc/l, and lime leaf extract 100 cc/l. The application time interval, which has four levels—3 days, 6 days, 9 days, and 12 days—is the second element. 48 experimental units were created by combining 16 treatment combinations, each of which had three replications. There were 192 plants total because there were 4 plants per experimental unit and 2 plants were used as samples. The data is statistically analyzed before being subjected to the BNJ test. The outcomes demonstrated that not all parameters were affected by interactions and combinations of application intervals and different insecticide types, including the percentage of flowers to fruit, age at first harvest, fruit weight per plant, fruit weight per fruit, percentage of fruit flies attacked, other types of pests that attack, and age of disease across all treatments.","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"2 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":"116696857","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}
