Abstract

Oil palm frond juice is a byproduct of the palm oil harvesting process, containing frond juice containing glucose, sucrose, and fructose. They are suitable for use as a fermentation raw material, thereby increasing the added value of the fronds. As a fermentation medium, frond juice does not inhibit microbial growth and poses no health or safety risks. The purpose of this study was to determine the effect of fermentation medium pH on bacterial cellulose from oil palm frond juice. Bacterial cellulose was produced using Acetobacter Xylinum. Oil palm frond juice was prepared at 100 ml/g with the addition of protein with different pH media fermented for 8 days at room temperature in statistical conditions. The results of the thickness and weight of the best cellulose bacteria of pH 5 medium were 0.78 cm and 393.015 g/L. FE-SEM micrograph analysis for bacterial cellulose showed typical peaks found in cellulose with typical fibril threads. pH 3 had the lowest crystallinity value and the best crystallinity was at pH 5 based on FWHM. 1106 and 1423 cm-1 wave number is the C-O-C or C-O bond areas which are one of the bonds of the main chain of bacterial cellulose and the best result tensile strength is the pH 5 treatment with a strength of 261.645 MPa

Abstract

The expansion of private oil palm plantations in Indonesia remains a critical issue due to the country’s position as the world’s largest crude palm oil (CPO) producer, with production reaching 48.23 million tonnes in 2023. This study aims to analyze the potential, constraints, and strategic opportunities for plantation extensification, particularly through the utilization of marginal lands (S2 and S3) and corporate expansion strategies such as mergers, acquisitions, and partnership schemes. A systematic literature review was conducted by synthesizing peer-reviewed journals, government statistics, and institutional reports selected based on inclusion and exclusion criteria to capture current dynamics of oil palm development in Indonesia. The findings indicate that the availability of highly suitable agricultural land (S1) is increasingly limited, encouraging companies to explore alternative strategies such as the optimization of degraded and idle lands, strengthening smallholder partnership schemes (plasma), and implementing replanting programs such as Peremajaan Sawit Rakyat (PSR). However, these opportunities are constrained by stricter environmental governance, land-use regulations, and increasing global sustainability requirements. The review further shows that S2 and S3 lands present significant biophysical limitations, including high soil acidity, poor drainage, and aluminium toxicity, which increase production costs and require advanced agronomic management. Socio-economic challenges such as land conflicts and unequal benefit distribution also continue to affect plantation expansion outcomes. This study concludes that Indonesia’s palm oil development is gradually shifting from land extensification toward productivity intensification. This transition highlights the need for stronger sustainability governance through ISPO and RSPO certification systems, improved environmental management practices, and more inclusive stakeholder engagement to ensure that plantation development remains economically viable, environmentally responsible, and socially equitable.

Abstract

The optimization of land use in immature oil palm plantations (non-yielding stage) is crucial to enhancing productivity and supporting sustainable agriculture. This study aimed to evaluate the effect of corn intercropping systems on vegetative growth, yield, and land-use efficiency in immature oil palm plantations. An experimental method with a Randomized Block Design was employed, consisting of two treatments: corn monoculture (control) and corn intercropped in the inter-row spaces of immature oil palms, each replicated three times. Observed parameters included plant height, number of leaves, cob weight, grain yield, and Land Equivalent Ratio (LER). The results demonstrated that intercropped corn exhibited higher vegetative growth, including increased plant height and leaf number, due to optimal utilization of growing space and improved microclimatic conditions, such as stable soil moisture and light shading. Generative growth also improved, as evidenced by higher cob weight and grain yield, which reached 7.6 t/ha compared to 6.9 t/ha in monoculture. The LER value of 1.10 indicated a 10% higher land-use efficiency in intercropping systems. Positive interactions among crops minimized competition for nutrients and water, enhanced weed control, and maintained stable microclimatic conditions, contributing to sustainable plantation management. Economically, intercropping provided additional income for farmers during the immature phase of oil palms without compromising the main crop. In conclusion, corn intercropping in immature oil palm plantations optimizes space, improves both vegetative and generative growth, enhances yield per unit area, increases LER, and offers ecological and economic benefits, making it a viable and sustainable strategy for maximizing productivity and supporting diversified agricultural systems.
