Abstract

Palm oil, a native crop of West Africa, emerged as a key industrial commodity in the 19th century, fundamentally shaping economic and environmental landscapes in both Europe and Southeast Asia. While its importance in European industrialization has been widely acknowledged, the early colonial expansion of oil palm cultivation in Indonesia and its impact on deforestation remains less discussed. This paper explores the intertwined economic, political, and environmental dimensions of palm oil trade in Europe post-1800 and the early plantation-based land conversion in Indonesia before 1945. Drawing on archival sources, historical records, and academic studies, it highlights the dual role of palm oil as both an enabler of industrial progress and a driver of ecological transformation.

Abstract

Endophytic microbes are microbes capable of colonizing and symbiotic with plant tissues. Trichoderma has been known as an endophytic fungus with a symbiotic relationship of mutualism including root colonization by helping root growth, nutrient absorption and resistance to stress and pathogens. This study consists of two steps, namely: (1) isolation and identification of Trichoderma, (2) endophytic test of Trichoderma isolate by root staining method and plant root culture. Seven isolates were shown to result in better plant growth and plant roots. Based on plant root culture tests, it was found that all plants contained Trichoderma, but based on T. Koningii and T. Polysporum root staining tests. It cannot be certain to colonize the root tissue of test plants. Based on the test results, Trichoderma has the potential to be a biological fertilizer (Biofertilizer) that can help optimal plant growth and can be applied in agriculture that applies the concept of sustainability.

Abstract

Nowadays plantation has change to more sustainable agricultural system towards effectivity, smart system and not only environmentally friendly but also in sustainability aspects. This study aims to explore Trichoderma as biofertilizer with bioantagonistic ability. The experiment design to test Trichoderma against Fusarium Oxysporum (Wilt Desease) and Thrips (pathogen) in aclimatisation test in tomato and chili plant. The result in antagonistic against Fusarium, T. harzianum B and T. cacao 29 have good inhibitory, namely around 70% of the resistance percentage. While T. Koninggii or T. Pseudokoningii (DT 38) was the weakest. Based on that Trichoderma approved has bioantagonistic ability against Fusarium invasion. But for large scale implementation, formulation and perfection microbial isolate are needed.

Abstract

Thrips is a pathogen insect that commonly attacked crop plant. Tomato and chili are essential crop plant in indonesia. In order to tackle this problem not only environmentally friendly but also in sustainability aspects, bioinsecticide agent are explored. This study aims to explore Trichoderma as endhopytic fungi with bioinsecticide ability. The experiment design to test Trichoderma Thrips in aclimatisation test for tomato and chili plant. The result in controling test against Thrips, T. DT 38 and T koningii was the best resistence while T harzianum B was the worst. This isolate can help slowing the effect of Thrips invasion. Based on that Trichoderma approved has bioinsecticide ability against Thriips invasion. But for effective implementation, formulation and perfection microbial isolate are needed.

Abstract

The increasing global demand for palm oil has driven the expansion of oil palm cultivation into peatland areas, raising concerns over environmental sustainability. This study investigates the impact of different land uses on soil microbial diversity and physicochemical properties by comparing three ecosystems: peat soil planted with oil palm (GS), peat soil with natural fern vegetation (GNS), and mineral soil cultivated with oil palm (MS). Physicochemical parameters including organic carbon, cellulose, and lignin content were analyzed, followed by 16S rRNA gene sequencing (V3-V4 regions) using the Illumina MiSeq platform. Sequencing data were processed using the QIIME2 pipeline and classified with the SILVA v.138 database. Results show that while MS had the highest microbial diversity, GS and GNS also supported diverse bacterial communities. Organic carbon, cellulose, and lignin were more abundant in GNS and GS than in MS, reflecting the influence of vegetation on soil composition. Dominant bacterial phyla across all sites included Proteobacteria, Actinobacteria, Firmicutes, and Acidobacteria. These findings suggest that oil palm cultivation on peatlands, when properly managed, does not necessarily reduce microbial diversity. Environmental factors such as vegetation cover, soil type, and water table levels play key roles in shaping microbial communities in tropical soils.
