Abstract

One of the pests that attacks oil palm plants is Oryctes rhinoceros Linn, known as a pest that borers oil palm shoots by sucking fluids and making holes in the midribs of leaves, stems and fruit. This horn beetle pest attacks oil palm plants planted in the field until they are 2.5 years old by destroying the growing point, resulting in damage to young leaves. So far, control has been carried out using chemical pesticides. The consequences of excessive use of pesticides can cause environmental problems. To avoid these consequences, natural horn beetle pest control is carried out using pineapple juice. This program is carried out to provide knowledge to the public about how to control horn beetle pests (Oryctes Rhinoceros) using fruit traps containing pineapple fruit. Socialization activities for controlling horn beetles (Oryctes Rhinoceros) using fruit traps containing pineapple fruit in Payarengas Village, Hinai District, Langkat Regency for 1 month from 14 August to 14 September 2023. Installing fruit traps containing pineapple fruit in the land shows potential as a pest control horn beetles naturally. With community service activities, oil palm farmers can provide education and innovation in controlling horn beetle pests using fruit traps made from pineapples.

Abstract

This study aims to analyse the density of microalgae mixculture cultivated in POME media with varying concentrations and to evaluate the effect of POME concentration on microalgae growth. Microalgae mixculture was cultivated in POME media with three concentration variations, namely 10%, 20%, and 30%. Cultivation was carried out for 15 days with cell density observations every three days using a haemocytometer. The results showed that microalgae density increased over time in all treatments. A POME concentration of 30% produced the highest microalgae density at each observation time, with a maximum density of 12,564 cells/ml on the 15th day, followed by concentrations of 20% and 10% at 11,980 cells/ml and 10,080 cells/ml, respectively. These results indicate that an increase in POME concentration has a positive effect on the growth of microalgae mixculture within the concentration range used. Microalgae density increased with cultivation time in all treatments. A 30% POME concentration resulted in the highest microalgae density, indicating that the higher nutrient availability in POME supports microalgae growth. Thus, POME has the potential to be utilised as an alternative medium for microalgae cultivation as well as an effort to manage palm oil industry wastewater.

Abstract

Palm oil mill boiler ash is a solid industrial waste available in large quantities, but its utilization is still limited. This waste has alkaline properties and nutrient content that has the potential to improve the physical-chemical properties of tropical acid soils, such as pH, cation exchange capacity, and macronutrient availability, making it a potential sustainable soil ameliorant. This study aims to process organic fertilizer, namely an organomineral product based on boiler ash, with the aim of evaluating its chemical characteristics and assessing its potential application as a soil ameliorant. The analysis results show that Puler has a pH value of 9 and a nutrient composition that can improve soil quality without heavy metal concentrations above the Indonesian national standard threshold. These findings indicate that Puler can be an efficient alternative ameliorant and supports the utilization of palm oil industry waste. In addition, this puler also meets the criteria for organic fertilizer standards according to SNI 7763:2024

Abstract

This research is motivated by the importance of soil fertility in supporting oil palm productivity through the availability of Nitrogen (N), Phosphorus (P), Potassium (K), and C-organic nutrients. The results showed that the total N content on sloping and flat land had an average of 0.13% and 0.12%, respectively, with a low category. The available P content had an average of 27.40 ppm on sloping land and 26.61 ppm on flat land with a high category. In general, the K content was classified as moderate and C-organic was classified as low in both land conditions. The t-test results showed no significant difference between flat and sloping land regarding the analyze dnutrient content. Soil functions as a medium for providing nutrients, but intensive management and continuous use of chemical fertilizers can reduce soil quality, especially organic matter. Therefore, analysis of N, P, K and C-organic is necessary to evaluate soil fertility and determine the appropriate fertilization strategy. The elements N, P, and K are essential macronutrients for plant growth, while organic C plays a role in improving the physical, chemical, and biological properties of the soil. The research was conducted at the Silau Dunia Plantation, Afdeling III, PT. Perkebunan Nusantara IV Regional I from February 2026 to May 2026, using a comparative quantitative method with laboratory analysis. Soil samples were taken purposively on flat and sloping land using the composite method (three replications). The parameters analyzed included total N, available P, K, and organic C, then tested using a t-test. The results showed that total N was low, available P was high, K was moderate, and organic C was low in both land conditions. There was no significant difference between flat and sloping land. Nutrient variations are thought to be more influenced by land management, fertilization, and environmental conditions.

Abstract

Mung bean plants include legume plants whose roots have root nodules which are a symbiosis between the roots and Rhizobium japonicum bacteria. Root nodules function to fix free nitrogen elements, besides that they can also fertilize the soil because they can save the use of NH3 available in the soil and provide nitrogen elements to the soil.Rhizobium is a genus of soil bacteria that are able to symbiotize with plants. There are many types of Rhizobium bacteria, especially in soils with high organic matter content. This study was conducted to determine the compatibility of Rhizobium japonic in mung bean plants (Vigna radiata L) with Rhizobium sp grown on Mucuna bracteata land. To determine the effect of some phosphate fertilizers on the modulation of mung bean (Vigna radiata L.) The results showed that the application of Rhizobium japonicum on mung bean (Vigna radiata L) with Mucuna bracteata land did not show a significantly different adjustment (compatibility) to the height and number of plant leaves. The P0 treatment showed significant differences in the root nodule parameters of the P1, P2 and P3 treatments. Phosphate fertilizer with 50% RP TSP content is the best composition.

Abstract

Soil fertility is one of the main factors affecting oil palm productivity, particularly in highland areas with varying topographic conditions. Differences in land slope are believed to influence the distribution of soil nutrients due to erosion and nutrient leaching. This study aims to analyze the content of nitrogen (N), phosphorus (P), potassium (K), organic carbon, and topsoil pH on flat and sloping land at the Bah Birong Ulu Plantation, PTPN IV Regional II. The study employs a quantitative approach using field survey methods and descriptive analysis. Soil samples were collected from flat and sloping land using a soil auger at several observation points. Laboratory analysis was conducted to determine nitrogen content using the Kjeldahl method, phosphorus using the antimony molybdate colorimetric method, potassium using flame photometry, organic carbon using the Walkley and Black method, and pH measurement using a pH meter. The research data were analyzed using a two-sample t-test under the assumption of unequal variances. The results of the study indicate that there are no statistically significant differences in the nitrogen, phosphorus, potassium, organic carbon, and soil pH levels between flat and sloped land. The average nitrogen content in sloped soil was 0.53% and in flat soil was 0.50%, organic carbon content was 1.37% and 1.17%, respectively; phosphorus content was 33.45 ppm and 37.65 ppm; potassium content was 0.637 me/100 g and 0.611 me/100 g; and soil pH was 5.34 and 5.80. These results indicate that topographic conditions have not yet had a significant effect on the distribution of soil nutrients at the study site.\n\nThis study concludes that plantation management practices such as fertilization, soil conservation, and organic matter management have a greater influence than land slope conditions in maintaining soil nutrient stability. It is hoped that these findings will serve as a basis for developing more effective soil fertility management strategies and fertilization recommendations for oil palm plantations in highland areas.
