Abstract

The extreme weather condition El Nino can cause Indonesia to experience a prolonged dry season, while La Nina causes a prolonged rainy season. These conditions affect the availability of water in oil palm plantations and affect the physiological processes of oil palm. This research aims to compare the NDVI index and SAVI index using Landsat 8 satellite imagery in the oil palm plantations of PT. Wanapotensi Guna during El Nino and La Nina. Landsat 8 satellite imagery recorded in August 2019 describes El Nino conditions and recorded in August 2020 describes La Niña conditions in the study area were downloaded from the USGS website. The NDVI and SAVI indices were analyzed using ArcGIS 10.5 software. The research results show the value of the NDVI index and SAVI index in the oil palm plantation area of ​​PT. Wanapotesi Guna has a value that is not much different in El Nino and La Nina conditions. The NDVI index value in El Nino conditions has a range of 0.07-0.46 and in La Nina conditions has a range of 0.13-0.44. Likewise, the SAVI index value in El Nino conditions has a range of 0.11-0.70 and in La Nina conditions has a range of 0.20-0.69. So it can be concluded that the NDVI index and SAVI index obtained from Landsat 8 satellite imagery cannot describe significant differences in index values ​​in oil palm plantation areas due to differences in the extreme weather conditions of El Nino and La Nina.

Abstract

Weed control during replanting activities is an important activity. In general, weed control was done using a knapsack sprayer, but currently weed control can also be done using a drone sprayer. This research was conducted to compare the effectiveness and efficiency of weed control using knapsack sprayers and drone sprayers. This research compares the application of knapsack sprayers and drone sprayers in controlling weeds during replanting of oil palm plantations which includes the time required for the weeds to die, the duration of time required for spraying, and the costs required. The data obtained were analyzed using the independent T test. The results of the research show that using a drone sprayer to control weeds during replanting is more efficient in terms of time and cost than using a knapsack sprayer, while in terms of effectiveness in killing weeds there is no real difference between both. Drone sprayers provide a better alternative for weed control when replanting in oil palm plantations.

Abstract

Oil palm plantations are one of the important carbon stocks for climate change mitigation because of their ability to store carbon and absorb free carbon from the air. This study aims to calculate carbon stocks at various stages of oil palm growth. The samples in this study were oil palm producing plants with various age classes; young plants (3-8 years), juvenile plants (9-14 years), and old plants (> 21 years) taken with a sample of 3 plots with 1 plot of 10 trees each in each age class variation using a quadrant (sample plot) plot size of 20 x 60 m with 3 replications. The sampling of understory vegetation was carried out in a measurement plot with a size of 1 m x 1 m as much as 1 sample placed in each plot of oil palm stand biomass measurement. The study was conducted using a carbon stock measurement method with a non-destructive approach using an allometric equation. In young, juvenile, and old oil palm plants. on sample plots according to the predetermined age groups. The research samples were selected by purposive sampling. In each sample, carbon stocks were measured in the oil palm plants and floor vegetation carbon stocks. The results of the study showed that carbon stock analysis showed a close relationship with plant age. Oil palm plant carbon stocks continued to increase with increasing plant age. Therefore, it can be concluded that oil palm biomass increases with increasing age in young plants (3.77 tons/ha), adolescents (12.61tons/ha), and old (>21 years, 167.82 tons/ha).

Abstract

Oil palm productivity is affected by many factors, one of which is weeds that can cause the oil palm productivity to not be maximized. Psychotria serpens is an example of a weed in oil palm plantations. This weed grows creeping in the circle and path so it disrupts oil palm management. This study was conducted to determine the effectiveness of isopropyl amine glyphosate, triclopyr and glufosinate herbicides in controlling Psychotria serpens weeds in oil palm plantations. This research was conducted at PT. Bahana Karya Semesta, Sungai Mentawak Estate, Air Hitam District, Sarolangun Regency, Jambi from March to April 2023. The study used a factorial experiment consisting of 2 factors and arranged in a completely randomized design with 3 replications. The first factor was the type of active ingredient consisting of isopropyl amine glyphosate, triclopyr, and glufosinate, the second factor is the dose of herbicide formulation which is 0.15ml/m2, 0.30ml/m2, 0.45ml/m2, and 0.6ml/m2. Observations were made for 5 weeks. The results of observations were analyzed using oneway anova which was further tested using DMRT 5%. The results was Glyphosate and Glufosinate at all formulation doses could not control Psychotria serpens. Triclopyr at formulation doses 0.15ml/m2 and 0.30ml/m2 was not able to control Psychotria serpens, and at formulation doses 0.45ml/m2 and 0.6ml/m2 showed death in Psychotria serpens. Based on the results of the study, it can be concluded that the best type of active ingredient in controlling Psychotria serpens weeds was the active ingredient Triclopyr with a formulation dose 0.45ml/m2.

Abstract

Oil palm nursery is generally conducted through a two-stage system, namely the pre-nursery stage and the main nursery stage. In the pre-nursery stage, seedlings require watering of 0.1–0.3 liters per day with a watering frequency of twice daily, in the morning and evening. Meanwhile, shading serves to protect against high sunlight intensity. This study aims to investigate the effect of light intensity and watering frequency on the growth of oil palm seedlings in the pre-nursery stage. The study was conducted from June 2024 to September 2024. It employed a factorial experiment method arranged in a split-plot design with two factors. The first factor (main plot) was light intensity, consisting of three levels: 3,500, 2,000, and 1,000 foot candles. The second factor (subplot) was watering frequency, consisting of three levels: twice a day, once a day, and once every two days with a water volume of 200 ml/day. Each treatment was replicated four times. Data were analyzed using analysis of variance (ANOVA), and if significant differences were found, the Duncan Multiple Range Test (DMRT) was applied. The ANOVA results showed a significant interaction between light intensity and watering frequency on the growth of oil palm seedlings in the pre-nursery stage, specifically in the parameter of seedling fresh weight. Light intensities of 1,000 and 2,000 foot candles resulted in taller seedlings compared to 3,500 foot candles, while a light intensity of 3,500 foot candles influenced root growth. Watering frequencies of twice a day and once a day showed better seedling growth compared to watering once every two days.
