Abstract

The development of oil palm plantations begins with the procurement of quality seeds. This effort is carried out through the use of mycorrhizal fungi as biological fertilizers and and improvement of seedling planting media. This study aims to determine the effect of mycorrhiza dose with the mixed composition of rice husk charcoal and top soil on the growth of oil palm seedlings in the pre-nursery. This research was a factorial experiment arranged in a completely randomized design. The composition of the planting medium consists of four levels: top soil, 25% husk charcoal with 75% humus, 50% husk charcoal plus 50% top soil, and 100% husk charcoal solely. The dose of mycorrhizal biofertilizer consists of three levels, namely: 0.5 and 10 grams per seed. The results of this study indicated that the composition of the media or the application of mycorrhizal biofertilizers had no significant effect on the growth of oil palm seedlings in prenursery. The largest seedling leaf area was produced by seedlings planted on media containing husk charcoal which was given 10 grams of mycorrhizal biofertilizer.

Abstract

Liquid organic fertilizer provides nutrients, increases good microorganisms and improves the physical properties of the soil, especially when used in oil palm nurseries. This research was conducted with the aim of determining the effect of providing liquid organic fertilizer and NPK on the growth of oil palm seedlings in the pre-nursery. This research uses a factorial experimental method arranged in a Completely Randomized Design (CRD) consisting of two factors. The first factor is liquid organic fertilizer which consists of 4 levels, namely Control/no fertilizer, 3 ml, 5 ml 8 ml. The second factor is NPK which consists of 4 levels, namely N1: Control/no fertilizer, N2: 1 g/plant, N3: 2 g/plant, N4: 3 g/plant. Each treatment was repeated 5 times. The data obtained were analyzed using Analysis of Variance (anova) with a level of 5%. Data that were significantly different were further tested with DMRT at a level of 5%. The results showed that there was a real interaction between liquid organic fertilizer and NPK on stem diameter. The best growth of oil palm seedlings at a dose of 1 g NPK fertilizer with 8 ml liquid organic fertilizer showed a value of 7.06 mm, a 2 g dose of NPK with a control liquid organic fertilizer showed a value of 7.02 mm, a 2 g dose of NPK and a dose of liquid organic fertilizer 3 ml shows a value of 7.00 mm. Real interaction between liquid organic fertilizer and NPK on crown fresh weight diameter. NPK at a dose of 1 g and POC at a dose of 3 ml showed a value of 6.46 g. Providing liquid organic fertilizer did not have a real effect on oil palm seedlings, while NPK at a dose of 1 g/plant had an effect on oil palm seedlings.

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

Environmental conditions can affect insect diversity. Different plantation conditions give rise to changes in the composition of insects. The study aims to determine the diversity of insects in high and low topography. The research was conducted at PT. Djuandasawit Lestari, Muara Tawas Estate located in Musi Rawas, South Sumatra, from December 2022 to March 2023.  The study used purposive sampling methods that are descriptive and exploratory. The study used 2 plantation blocks R58 and Q59), each block has a high and low topographic area. Each block made 10 observation plots with a size of 5 x 5 meters spread in five plots for low and high areas by taking into account the diversity of vegetation. Each research plot was installed with 4 traps, namely pan trap, pitfall trap, sticky trap and sweep net for 10 days of observation. The insects were identified their classification, and diversity index calculated by the Shannon-Wienner and Simpson dominance. The results showed that the abundance of insects in low-level topography was more than in high-altitude topography. A total of 708 individuals were found spread across 12 orders and 27 families in low topography, while in high topography only 537 individuals were found spread across 12 orders and 26 families. The index of insect dominance in lowly and high areas is low. The insects found are mostly predatory insects.

Abstract

Palm oil productivity is influenced by many factors. One factor is crop rotation. Harvest rotation greatly influences productivity in oil palm plantations. Obstructed harvest rotation causes the number of fruit bunches to increase in an area compared to the weight of fresh fruit bunches (FFB) harvested. The percentage of brondol in oil palm plantations is very important because it will affect the average bushel weight (BJR) and payments to employees for oil palm plantation companies. The decrease in BJR due to the high percentage of brondol will also have an impact on the morale of workers, especially harvesters on oil palm plantations because the harvest base will be higher to get a harvest premium. This research aims to determine the comparison of the percentage of brondol in various areas, namely hilly, lowland and plain areas and to find out the causes of the high percentage of brondol in the treatment blocks. This research uses an agronomic trait survey method by observing secondary data on productivity and percentage of brondol in the last six years, then analyzed using the t test at a level of 5%.  This research was carried out at PT. Cahaya Nusa Gemilang (CNG) Kenanga Estate garden, Marau District, Ketapang Regency, West Kalimantan. The results of the analysis show that plain areas have the best productivity and percentage of brondol compared to lowland and hilly areas.
