Abstract

Land use is one of the key factors influencing both the physical and chemical properties of soil, including characteristics such as soil color and texture. This study aimed to characterize the physicochemical properties and fertility criteria of soils under different land use types. Five land use categories were selected for investigation: shrubs, grasses, Eucalyptus sp., mixed plantations, and oil palm. Each land use type consisted of three replications. Soil sampling was conducted at five designated points per land use type, with samples collected from a depth of 0–30 cm, resulting in a total of 75 samples. The research was carried out over a three-month period from April to July 2022 using a land survey approach and purposive sampling technique. The observed parameters included soil color, texture, permeability, pH, total nitrogen (N), total phosphorus (P), total potassium (K), organic carbon (C), base saturation, and cation exchange capacity (CEC). The results revealed that the soil color was predominantly black (2.5Y 2/1), with a sandy loam texture. Soil permeability ranged from moderately fast to fast (6.33–23.68 cm·h⁻¹), while soil pH was acidic (4.75–5.11). Total nitrogen was categorized as low (0.11–0.18%), total phosphorus as very low (10.73–27.56 mg·100g⁻¹), and total potassium as very low to low (3.60–10.87 mg·100g⁻¹). Organic carbon content was low to moderate (1.49–2.45%), base saturation was very low (3.37–13.59%), and CEC was classified as very low to low (4.39–8.62 cmol(+)/kg).

Abstract

This extension activity was carried out in Sungai Majo Village, Kubu Sub-district, Rokan Hilir Regency with the objective of enhancing the knowledge and skills of oil palm farmers in recognizing nutrient deficiency symptoms and implementing strategies for plant pest organism control. The methods applied included lectures, participatory discussions, and field demonstrations. The materials delivered covered the identification of nutrient deficiency symptoms of both macro and micro elements, such as nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), and boron (B), along with their implications for plant growth and productivity. In addition, information was provided on common PPOs found in oil palm plantations and appropriate control techniques based on the principles of integrated crop management. The evaluation results showed an increase in farmers' understanding of nutrient deficiency symptoms from 30% before the activity to 75% after the activity, as well as an increase in understanding of OPT control from 40% to 70%. More than 80% of participants were able to independently identify symptoms of K and Mg deficiencies, and 75% of participants understood balanced fertilization techniques according to recommendations. Farmers also became more capable of recognizing pest attacks and understood environmentally friendly control alternatives, including mechanical, cultural, and biological approaches. Overall, this activity contributed to strengthening farmers’ capacity in sustainable oil palm management.

Abstract. Hamzah A, Saputra R, Puspita F, Nasrul B, Irfandri, Depari NS. 2021. Ganoderma diversity from smallholder oil palm plantations in peatlands of Kampar District, Indonesia, based on mycelia morphology and somatic incompatibility. Biodiversitas 22: 16-22. Basal Stem Rot disease is caused by the pathogenic fungus Ganoderma boninense which has caused major economic losses in the palm oil industry. Ganoderma boninense has been reported not only infecting crops in the field, but also attacking at the immature phase of the plant even in the nursery. Studies related to Ganoderma diversity in oil palm plantations in Riau, Indonesia have not been widely reported. Ganoderma genetic diversity is important because its provide information regarding the mechanism of infection and the spatial distribution. The Ganoderma spp. isolates were collected from three blocks of smallholder oil palm plantation in Deli Makmur Village, Kampar District, Riau Province, Indonesia and brought to Plant Disease Laboratory, Faculty of Agriculture, Riau University, Pekanbaru, Indonesia. This experimental research was conducted using six Ganoderma isolates (Gan1, Gan2, Gan3, Gan4, Gan5, and Gan6) on the parameters of colony diameter and growth speed, while for the parameters of the morphological diversity of Ganoderma mycelium and the diversity based on somatic incompatibility assay was carried out descriptively. The results of this study show that oil palm plants in smallholder plantations in Kampar District are infected by two groups of Ganoderma based on morphology characteristics using UPGMA dendrogram, but different among isolates based on genetically using somatic incompatibility assay. For the next confirmation, it is necessary to further identify whether the six isolates are different species using molecular identification.

Abstract

Rice husk waste is a major by-product of rice milling that is abundant in agricultural areas such as Simpang Kubu Village, Kampar Regency, and is often burned or discarded, causing environmental pollution. This community service program aimed to enhance local knowledge, skills, and awareness in processing rice husk waste into biochar as an eco-friendly and economically valuable soil amendment. The activity was carried out in August–September 2025 using the Participatory Rural Appraisal (PRA) approach, involving 31 participants from farmer groups, housewives, and village officials. The methods included socialization, hands-on training in biochar production using a 208-liter rotary drum pyrolizer, and evaluation through pre- and post-tests. The results showed a significant increase in participants’ knowledge, from an average of 31% before training to 87.5% after training, with 92.9% expressing willingness to produce biochar and 100% interested in applying it to their farms. These findings indicate that an educational and participatory approach effectively improves community behavior and self-reliance in agricultural waste management. In conclusion, this program successfully strengthened community capacity to convert rice husk waste into useful products while promoting sustainable agriculture and rural economic development. The main challenges identified were limited production tools and participants’ confidence in assessing biochar quality; therefore, continued mentoring is needed to ensure independent and sustainable implementation of the technology.
