Abstract

The success of oil palm cultivation is closely related to the quality of seedlings produced in the nursery phase. This study evaluated the potential acceleration of early growth in oil palm seedlings by optimizing biochar-based growing media combined with organic–inorganic fertilizer formulations. The experiment was arranged in a Completely Randomized Design (CRD) with three treatments: M1 (10 g urea + 50 g organic fertilizer), M2 (10 g NPK + 50 g organic fertilizer), and M3 (10 g urea + 10 g NPK). Each treatment was replicated ten times, resulting in 30 seedlings per replicate. Growth observations were conducted weekly from week 4 to week 20 (approximately four months), covering seedling height, leaf number, and stem diameter. Data were analyzed using one-way ANOVA at a 5% significance level, complemented by effect size analysis (?² and ?²) at week 20 to quantify the biological treatment's influence, and descriptive evaluation of the growth trend. The results showed no significant differences among treatments (p > 0.05). However, all treatments exceeded the physiological growth standards for four-month-old seedlings. M3 produced the highest growth response, with relative increases of 200% in height, 177.8% in leaf number, and 133.3% in stem diameter compared with the standard. These findings suggest that biochar-based growing media, combined with integrated organic-inorganic fertilizer formulations, can enhance early vegetative growth, although statistical significance has not yet been achieved within four months. Further observation up to ten months is recommended to validate the consistency of this growth acceleration.

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

The oil palm plantation industry adheres to the concept of sustainability paradigm on 3 main principles, namely profit, people (social society) and planet (environment). One of the social issues is to keep community involvement in running the oil palm plantation business process stable. With the existence of social problems in the community regarding oil palm plantations, the company as a stakeholder seeks to implement Corporate Social Responsibility (CSR) programs with the hope of establishing a harmonious relationship between the company and the local community and the establishment of cooperation so that the community benefits both socially, economically and culturally. This potential mapping program is expected to be the foundation for oil palm plantation companies to determine appropriate coaching programs to improve the welfare of the community around the company by analyzing the description of production aspects, market aspects, administrative financial aspects, human resource aspects, sustainability aspects in each potential business. The research is focused on 2 sub-districts and 1 district in the province of Central Kalimantan. From the results of the analysis , it was concluded that the potential for CSR for horticulture committees and fisheries and livestock commodities became a priority program due to limited needs and supplies.

Abstract

Management of sandy soil in oil palm plantations requires location-specific technology that prioritizes sustainability principles. Palm oil mill Effluent (POME) has the potential to be a substitute for nutrients for oil palm plantations. This research aims to reveal the role of POME in improving soil and tissue nutrient status and increasing oil palm production on sandy soil. The research was conducted on eleven plantation blocks using POME and six blocks without by-products (30 ha block-1, sandy soil) of 12-13 years palm. Observations were carried out for 3 years, including harvest tonnage, number and weight of fresh fruit bunches (FFB) of palm oil, soil, and tissue nutrient content (N, P, K, Mg, Ca, Cu, and B), CEC, and soil organic carbon. The research results show that POME flatbed system application can increase the nutrient content, pH, CEC, and soil organic carbon in the low to medium range. This application can also increase the tissue nutrient content to the optimal range. Production, quantity, and weight of oil palm FFB on sandy soil applied by POME were increased compared to those without by-product application. This application can also reduce monthly fluctuations in palm oil production on sandy soil.
