Abstract

Oil palm replanting is critical for maintaining yields, improving farmer livelihoods, and reducing expansion to forested areas. Indonesia’s smallholder farmers manage a large proportion of the national plantations but face declining productivity due to aging trees and substantial constraints in replanting programs. This study presents a systematic literature review of research published between 2015 and 2024 on smallholder oil palm replanting in Indonesia. Using PRISMA-based screening, this study applied Open Knowledge Maps and VOSviewer to examine research trends, thematic clusters, and knowledge gaps. The analysis identified five dominant themes: environmental impacts, biomass economic valuation, corporate farming schemes, institutional arrangements, and community-driven initiatives. Environmental studies focus on biodiversity and greenhouse gas emissions, whereas economic research examines subsidy effectiveness and productivity. Institutional analyses highlight policy frameworks and extension services, while community-oriented research explores farmer participation, collective action, and risk preferences. Despite increasing scholarly attention, major gaps remain in understanding replanting profitability, behavioral decision-making under risk, effective support mechanisms, and integrated sustainability dimensions. This study provides a comprehensive research map and outlines priorities for strengthening sustainable replanting strategies for Indonesian smallholders.

Abstract

Online food delivery (OFD) services can shape consumer habits through regular use. Although promotions attract consumers, they may also encourage food waste. This study analyzes factors influencing the intention to use OFD services and over-ordering behaviors by extending the Theory of Planned Behavior (TPB) with variables such as sales promotion and leftover reuse. The study used purposive sampling and collected data from an online survey of 253 OFD service users in Jabodetabek. Descriptive analysis and Partial Least Squares-Structural Equation Modeling (PLS-SEM) were applied. Results showed that most of the OFD users in this study were female residents of Bogor and Jakarta, aged 25 - 35 years old, single, holding a bachelor's degree, employed, with monthly incomes of IDR5,000,000 and IDR10,000,000, and spending IDR1,000,000 - IDR2,000,000 per month on food. Intention to use was influenced by attitude and subjective norms, while over-ordering was influenced by sales promotion and intention to use. The leftover reuse variable did not significantly influence the intention to use or over-ordering. Implications include encouraging continued OFD use through targeted advertising and features to help users manage consumption behavior, such as setting order reminders, providing nutritional information, and offering personalized portion recommendations. This study’s novelty lies in introducing a new variable and demonstrating that sales promotions can encourage over-ordering.
