INTERNSHIP REPORT BY : NURUL ARDIAN FITRIYANI LAND RESOURCE MANAGEMENT INTERNSHIP Background • Today tobacco is important in agribusiness and agroindustry • PT HM Sampoerna have an experimental garden for tobacco • In tobacco plants there are 3 important things that need to be considered to maintain the quality of tobacco leaves, including climate, plant nutrients (soil nutrients) and water availability. Competency goals and objectives • To get work experience and knowledge in the field as a form of application of theory during lectures • understanding about the management and irrigation systems that are applied in the cultivation of tobacco plants at the Sampoerna Agronomy Center. Sampoerna Agronomy Center SAC Location Tobacco Cultivation garden Escapade Cultivation Training Tobacco Cultivation provide tobacco seeds Seed multiplication Vission Mission • Developing economical and environmentally friendly agricultural technology to improve tobacco productivity and quality and cloves for tobacco and clove farmers in Indonesia • Increasing productivity and quality of chopped tobacco and cloves in Indonesia and promoting alternative technologies for tobacco sustainability Activity Tobacco and clove cultivation overview July Research Initiation July Protocol Assesment Tobacco Cultivatio n JulyAugust JulyOctober Final Assesment Monitoring Trial Implementat ion and Analysis Research Implemen tation JulyNovember AugustDecember Research Implementation FMC Micro Magnet Acidification and Stalk-cut Sludge - Monitoring - Observation -Analysis Research Implementation The optimal pH for tobacco ranges from 5.57.5. Volcanic ash will increase soil acidity. Urea fertilizer can Increase soil acidity. addition of water can increase water available to plants Asidification The treatment that shows the best performance both jepon and marakot is with KNO3 fertilizer under acidic conditions and extra water FMC Micro Magnet The treatment that shows the best permormance is highest application of micro magnet with no fertilizer reduction Sludge The treatment that shows the best performance is Sludge with 25% fertilizer reduction Based on laboratory analysis, Sludge application can improve soil physical properties better than compost, but the resistance of plants disease is low Stalk-cut On going On going Humic acid can improve soil properties, especially physical properties and increase nutrient uptake FMC MICRO MAGNET 2.

Environmental conditions due to eruptions in Jember affect soil conditions, the application of urea fertilizer will make the soil more acidic so that phosphate will be difficult to obtain. Increased rainfall can increase available water because Entisols soil types are easy to lose water 2. Water supply in the greenhouse is more uniform while the land is less uniform Recommendation 1. SAC's land should not be used for the cultivation of tobacco plants or the Solanaceae family. 2. Soil requires additional organic matter so that after cultivation, the remaining plants should be immersed in the soil. 3. Routine maintenance for irrigation in the land.
