Abstract

To attain national sugar self-sufficiency by 2030, the Indonesian government has issued Presidential Regulation No. 40/2023 stipulating acceleration of sugar self-sufficiency and supplies of bioethanol as a biofuel. This paper discusses strategies and practical programs to increase productivity as mandated by the Presidential Regulation, using literature reviews and a gap analysis on secondary data obtained from four demo-plots involving plantation companies and farmers. With a land size ranging from 4.4 to 8.4 hectares, each demo-plot applied bongkar ratoon (replacing ratoon with plant cane) and other key components of sugarcane's Good Agricultural Practices (GAP). They include plant variety and maturity recomposition, correct and timely doses of fertilization and water management. The results show that bongkar ratoon and GAP raise productivity from around 5 tons of sugar/hectare to 8.73 - 20.14 tons of sugar/hectare. While the results show promising potentials, expanding the demo-plots into large scale plantations is not straightforward, requiring comprehensive strategies, programs and action plans, some of which are outlined in this paper for both Holding Perkebunan Nusantara's smallholder- and own-plantations.

Abstract

Indonesia’s expanding gig economy has reshaped the labor market, offering flexibility while deepening social protection disparities. This study examines the gap in social protection coverage between formal employees and gig workers—online and local—within Indonesia’s employment landscape. Using microdata from August 2018, 2021, and 2023 National Labor Force Surveys (Sakernas), the analysis focuses on the service sector, where gig work is concentrated. A binary logistic regression with marginal effects was used to estimate the probability of workers’ participation in Indonesia’s social security programs. Findings revealed persistent, significant disparities: Online gig workers were 33% less likely and local gig workers 23% less likely to be covered than formal employees. These inequalities widened during and after the COVID-19 pandemic, especially in health and occupational accident insurance. Further analysis showed that disparities were more pronounced among male and urban workers. These results underscore structural vulnerabilities in Indonesia’s dual labor system and highlight the need for inclusive, adaptive social protection reforms. Recommendations include integrating gig workers into national social security schemes through shared contributions, strengthening digital and social protection literacy, and establishing a legal framework that recognizes platform-based employment as part of Indonesia’s labor market.
