Abstract

This research explores the role of digital media in marketing transformation across various industries, focusing on how these technologies are transforming traditional marketing strategies into more dynamic and focused ones. Analyses were conducted on a comparative basis to understand the different adoption and implementation rates of digital media in sectors such as retail, entertainment, agriculture and manufacturing. Findings show that industries that are more directly connected to consumers, such as retail and entertainment, have been quicker to adopt digital solutions, while industries with more complex supply chains face greater challenges. The study confirms the importance of digital media in providing greater marketing flexibility and efficiency, and encourages companies to adapt and innovate to maintain competitiveness in the evolving digital economy.

Abstract

This study analyses the optimisation of marketing functions to enhance the added value and competitiveness of Indonesian palm oil products through the holistic integration of eight key functions: purchasing, sales, transportation, storage, financing, risk insurance, quality standardisation, classification, and market information. Using a systematic literature review approach, the study consists of two main discussions: (1) the integration of operational functions that reduce transaction costs by 20-30% through the synchronisation of digital supply chains; and (2) the integration of strategic functions that support national downstreaming with a multiplier effect of Rp 3.2 trillion per Rp 1 trillion investment through sharia KUR financing, parametric insurance, and ISPO certification. The findings confirm that current marketing fragmentation causes disparities in farmer margins of £47-305/kg of fresh fruit bunches and only 65% utilisation of palm oil mills, which can be addressed through an integrated ERP-IoT-blockchain platform. Strategically, this optimisation strengthens Indonesia's position as a 55-60% global palm oil producer, supports B40 biodiesel, and meets EUDR regulations for sustainable competitiveness until 2035

Abstract

The palm oil industry is a strategic pillar of the Indonesian economy, making a significant contribution to Gross Domestic Product (GDP), exports and employment. However, the industry faces structural challenges in the form of a sub-optimal marketing system, a reliance on raw material exports, a negative image regarding sustainability, and logistical inefficiencies that increase distribution costs and reduce product quality. This study aims to examine strategies for optimising the marketing and logistics systems as an effort to enhance the economic value and sustainability of Indonesia’s palm oil industry. The method employed is a literature review using a descriptive qualitative approach. The research findings indicate that optimising the marketing system through the diversification of high-value derivative products (oleochemicals, biodiesel, oleofoods), strengthening sustainability certification (ISPO and RSPO), digitalising marketing (e-commerce and blockchain), and enhancing national branding can increase export value by up to 25–30 per cent and open access to premium markets. Meanwhile, optimising the logistics system through infrastructure modernisation (plantation roads, specialised ports), the integration of digital technology (Warehouse Management System, IoT, GPS tracking), the implementation of green logistics, and collaboration with state-owned logistics enterprises has the potential to reduce distribution costs by 25–30 per cent, maintain product quality, and lower the carbon footprint of the supply chain. Synergy between these two pillars creates a multiplier effect for enhancing global competitiveness, stabilising farmers’ prices, and ensuring environmental sustainability. This study recommends an integrated approach involving political commitment from the government through coherent cross-ministerial policies, sustainable investment from industry players, and inclusive multi-stakeholder collaboration to build an economical, sustainable, and inclusive palm oil industry for the welfare of the Indonesian people.
