Abstract

This study discusses the Effect of Coal and Potassium Fertilizers on the Flower and Production of Oil Palm Plants (Elaeis guineensis Jacq.). This study aimed to determine the interaction between coal fertilizer and potassium fertilizer, as well as the influence of each single factor, on the flower and production of oil palm plants, as well as the correlation between the observed variables. This study was conducted experimentally using a factorial Complete Random Design (RAL) with two aspects of treatment. The first aspect is the dosage of coal fertilizer with three levels: 0, 1, and 2 kg per plant per 6 months. The second aspect is the dosage of potassium fertilizer with 3 levels: 3, 4, and 5 kg per plant per 6 months. The results of the analysis showed that the combination of 1 kg of coal fertilizer and 5 kg of potassium fertilizer per plant was the best treatment. This treatment has been proven to accelerate the ripening time of fruit and significantly increase the production of oil palm plants.

Abstract

This study aims to evaluate the effects of super K organic fertilizer application on the flowering phases, yield components, and the relationships among observed variables of oil palm (Elaeis guineensis Jacq.), as well as to determine the fertilizer dose that provides the best response in yield components. The study was conducted over six months, from March to September 2024. The experiment was arranged in a Completely Randomized Design (CRD) with four levels of super K organic fertilizer application, namely K1 = 3 kg plant⁻¹, K2 = 4 kg plant⁻¹, K3 = 5 kg plant⁻¹, and K4 = 6 kg plant⁻¹. Each treatment was replicated five times, yielding 20 experimental units. Each experimental unit consisted of two sample plants, for a total of 40. The collected data were analyzed using analysis of variance (ANOVA) and further tested using Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that super K organic fertilizer application had no significant effect on the time to spathe emergence, time to flower emergence, time to female flower receptivity, time to male flower anthesis, sex ratio, and the number of fresh fruit bunches harvested per plant. However, super K organic fertilizer significantly affected the fruit maturation period and fresh fruit bunch weight per plant, with the 5 kg plant⁻¹ dose providing the best performance. Correlation analysis revealed strong to powerful relationships among several flowering variables and oil palm yield components.

Abstract

Post-harvest oil palm that does not comply with the Factory standart can cause losses in reducing the production of fresh fruit bunches. The objectives of this study are 1) To analyze he stages of harvest and the sources that result in the risk of harvesting oil palm FFB in each post-harvest chain that is traversed to the TPH at the Koperasi Petani Sawit Mandiri (KOPSA-M), Pangkalan Baru Village, Kampar Regency. 2) To analyze the amount of yield loss and the possible risk of harvesting oil palm FFB in each post-harvest chain That is traversed from the land to the TPH at the Koperasi Petani Sawit Mandiri (KOPSA-M) Pangkalan Baru Village, Siak Hulu District, Kampar Regency. The data analysis was descriptive quantitative research analysis. Sources of loss post-harvest of oil palm FFB at the Pangkalan Baru Village Independent Farmers Cooperative (KOPSA-M), Siak Hulu sub-district, Kampar district is the percentage of post-harvest loss of fresh fruit bunches (FFB). is equal to 5.21 percent of the total average FFB produced per plot (2 hectares). the losses are in the land, TPH, checking raw FFB and mill sorting. The percentage of losses in the land area is 1.73 percent of the total FFB yield. Meanwhile, the number of losses in the factory sorted amount was 2.70 percent and became the most significant loss for post-harvest FFB losses at KOPSA-M. The sources of post-harvest loss of FFB at KOPSA-M are harvest time, harvesting techniques. implemented by harvesters, cleanliness of plantation land, harvesting places (TPH), fruit and plant maintainers, and sunlight, human resources (HR) from oil palm harvesters,

Abstract

Coconut (Cocos nucifera L.) is a strategic plantation crop in Indonesia, playing important roles in society, the economy, and industry. Indragiri Hilir Regency is the largest producer of coconut in Riau Province; however, productivity has declined as plantations have aged. This study aimed to analyze the quality of coconut fruit based on plant age. A non-experimental comparative observational design was employed with three plant age treatments (15, 20, and 25 years). Each treatment was replicated six times, yielding 18 experimental units. Each unit consisted of two sample plants, totaling 36 plants. The measured parameters included endosperm thickness (mm), oil yield (%), and oil moisture content (%). For oil yield and moisture analysis, two mature coconuts were collected from each plant and analyzed in the laboratory, resulting in 36 samples. Data were analyzed using one-way ANOVA, and significant results were further tested using Tukey's HSD at the 5% level. The results showed that plant age had a considerable effect on endosperm thickness, oil yield, and moisture content. These findings suggest that plant age affects coconut fruit quality, with 25-year-old trees producing the highest-quality fruits in the Tembilahan Hulu District, Indragiri Hilir Regency. This study offers recommendations for coconut farmers to optimize cultivation strategies, thereby enhancing production and fruit quality.

Abstract

This study aimed to evaluate the effects of N, P, K, and Mg fertilization on improving growth parameters and productivity of oil palm plants subjected to over-pruning. The experiment was conducted using a completely randomized split-plot design with two factors: pruning treatment as the main factor and N, P, K, and Mg fertilization as the second factor. The observed parameters included the number of female inflorescences, number of male inflorescences, sex ratio, number of fruit bunches, bunch weight, fresh fruit weight, fresh fruit volume, mesocarp thickness, and fruit lipid content. The data obtained were statistically analyzed using analysis of variance, followed by Duncan’s New Multiple Range Test (DNMRT) at the 5% significance level. The results showed that the P1 treatment, representing normal pruning, combined with the N3 fertilization treatment improved several growth and productivity parameters, including the number of female inflorescences (5.02), number of fruit bunches (5.83), sex ratio (60.12%), fruit bunch weight (20.40 kg), fresh fruit weight (12.43 g), mesocarp thickness (3.93 mm), fresh fruit volume (12.59 mL), and fresh fruit lipid content (20.21%). In contrast, over-pruning tended to increase the number of male inflorescences (4.00), indicating a decline in the reproductive performance of the plants. In conclusion, normal pruning and the application of N, P, K, and Mg fertilizers significantly improved the growth and productivity of oil palm plants affected by over-pruning, particularly by increasing the number of female inflorescences, number of fruit bunches, sex ratio, fruit bunch weight, fresh fruit weight, mesocarp thickness, fresh fruit volume, and fresh fruit lipid content.
