Abstract

This study was conducted to analyze the effect of composting from oil palm fronds and soil type variations, as well as the interaction of these two factors on the development of oil palm seedlings at the main nursery stage at the Education and Research Garden (KP2) Instiper, Wedomartani Village, Sleman, Yogyakarta. The research method uses a factorial design with two factors arranged in a Complete Random Design (RAL), where the first factor is the dose of palm frond compost consisting of four levels, namely 0 grams as a control, 100 grams, 200 grams, and 300 grams, while the second factor includes three types of soil with different characteristics, namely regosol, latosol, and grumusol. Data analysis was carried out using ANOVA for treatments that showed significant differences. Based on the results of the analysis carried out, there was no significant interaction between the application of oil palm frond compost and soil type on the growth of seedlings in the main nursery, but separately it was found that the application of the highest dose of compost of 300 grams per polybag had a real effect on the growth of oil palm seedlings, while on the other hand, the use of latosol type soil showed a significant positive effect. Especially on the dry weight parameter of oil palm seedlings at the main nursery stage, which indicates that these two factors independently have an important role in optimizing the growth of oil palm seedlings

Abstract

This study aims to examine the effectiveness of attractants on the activity of the pollinating beetle Elaeidobius kamerunicus and its impact on the efficiency of pollination and palm oil (Elaeis guineensis) production at PT Menthobi Makmur Lestari, Lamandau Regency, Central Kalimantan. The study was conducted from May to July 2025 using a factorial randomized block design with two factors: topography (flat 0–8% and hilly 15–25%) and attractant doses (0, 1, 2, and 3 ml/ha) with three replications.The parameters observed included the frequency of E. kamerunicus visits to female flowers and the percentage of fruit set. The results showed that the topography factor, attractant dose, and their interaction significantly affected the number of E. kamerunicus visits and fruit set (p < 0.01). The combination of flat land with high attractant doses resulted in the highest visits (69.04 beetles/spike) and maximum fruit set (75.11%), while the hilly land without attractants showed the lowest results (34.60 beetles/spike; 61.22%). The application of attractants increased fruit set by more than 20% compared to the control, leading to an increase in bunch weight (BJR) of approximately 5.67 kg/bunch, additional production of about 1,151 kg FFB/ha per 1.5 months, and a potential income of Rp 3,683,200/ha, far exceeding the application cost of Rp 211,638/ha. These results indicate that the use of attractants is an effective and efficient agronomic strategy to improve palm oil productivity. Thus, attractants have proven to significantly enhance pollination efficiency and palm oil production, providing substantial economic benefits to farmers and supporting the sustainability of palm oil plantations. This approach offers an applicable and sustainable solution for agricultural practices, which can be applied to various locations with similar topographical conditions.
