Abstract

Inceptisols are widely distributed in tropical regions, including Indonesia, and are characterized by high rainfall and intensive weathering. These conditions promote severe nutrient leaching, low cation exchange capacity (CEC), and moderately to slightly acidic soil pH, thereby limiting nutrient availability, fertilizer-use efficiency, and crop productivity, particularly in oil palm (Elaeis guineensis) plantations. This study aimed to evaluate the effects of BIO SOLID 17, an organic soil conditioner derived from palm oil mill effluent (POME) sludge, on the chemical and physical properties of Inceptisol through a controlled incubation experiment. A two-month laboratory incubation was conducted using a randomized complete block design with five application rates of BIO SOLID 17 (0, 5, 10, 15, and 20 kg ha⁻¹), each with five replications. Observed parameters included soil pH, cation exchange capacity (CEC), and water-holding capacity (WHC), which were analyzed using standard methods. The results demonstrated that BIO SOLID 17 application significantly improved Inceptisol soil quality in a dose-dependent manner. Soil pH increased from strongly acidic conditions (4.85) in the control to near-neutral levels (6.19) at the highest application rate. Soil CEC also increased significantly from 34.41 to 47.49 cmolc kg⁻¹, indicating enhanced nutrient retention capacity. In addition, soil water-holding capacity increased from 46.82% to 55.81%, reflecting improvements in soil aggregation and moisture retention. Overall, BIO SOLID 17 shows strong potential as a sustainable organic soil amendment for improving the chemical and physical fertility of Inceptisol. The utilization of POME-based materials supports circular economy principles by converting agro-industrial waste into value-added agricultural inputs. Further field-scale studies are recommended to confirm effectiveness and determine optimal application rates under oil palm plantation systems.

Abstract

Hatch and carry is a breeding and distribution system for the primary pollinator of the oil palm, Elaeidobius kamerunicus. Information on the optimal distance for the Hatch and Carry application on pollination success and bunch productivity is still limited. This study aims to determine the effective distance of Hatch and Carry on fruit set and bunch weight in oil palm. The study used a quantitative method with a Completely Randomized Design (CRD), including Hatch and Carry distance treatments at radii of 10 m, 100 m, 200 m, 300 m, and 400 m, as well as assisted pollination techniques as a comparison. Data on fruit set and bunch weight were analyzed using analysis of variance (ANOVA) at the 95% confidence level, followed by the Duncan Multiple Range Test (DMRT). The results showed that the highest fruit set was observed at 10–200 m and was not significantly different, but decreased significantly at 300 m and 400 m. The same pattern also occurred for bunch weight, with the highest value at 100 m. The assisted pollination technique produces fruit set equivalent to the effective Hatch and Carry distance of 10–200 m. This study concluded that the effective distribution range of E. kamerunicus is within a radius of 200–300 m; thus, Hatch and Carry technology has the potential to be an efficient alternative for increasing oil palm productivity.
