Abstract

Indonesia is one of the world's leading pulp producers. Both domestic consumption and global demand are increasing annually. As Indonesia seeks to meet the escalating global demand for pulp raw materials, China is emerging as a major destination for its exports, which underscores the strategic importance of this market. This study aims to evaluate the comparative advantage of Indonesian pulp exports and to identify the price, cross-price and expenditure elasticities of pulp demand in the Chinese market. Using the Revealed Comparative Advantage (RCA) method and the Linear Approximation-Almost Ideal Demand System (LA/AIDS) model, this research analyzes annual time series data covering the period 2003-2022, focusing on the quantity and export value of chemical pulp (HS 470329). The results show that Indonesian pulp has a comparative advantage in the Chinese market, as indicated by Indonesia's RCA index greater than one. However, this comparative advantage is declining over time. At the same time, China's sustained increase in pulp consumption underscores the intensified competition among pulp-exporting countries for market share in China. Using the LA/AIDS model, the estimation results highlight a different dynamic in the Chinese pulp market: Japanese pulp emerges as a complementary product to Indonesian pulp, while Thailand and Brazilian pulp act as substitutes. These findings have valuable strategic implications for Indonesian policymakers and industry stakeholders in managing the complexities of global pulp trade dynamics

Abstract

Indonesia is a major cinnamon (Cinnamomum sp.) exporting country in the world. Previous research generally measured the information on competitiveness. To improve performance, export demand behavior should also be known. This study aimed to estimate Indonesia’s cinnamon export demand function. The panel data model was investigated using panel data exports to 11 country destinations from 2010 to 2020. The classical assumption test of heteroscedasticity and autocorrelation and the model specification test were conducted. The results show that the export demand function can be represented well by the fixed-effects model, which explains about 96% of its variance. The obtained income and price elasticities were 1.08 and -0.30, indicating normal goods with inelastic export demand. It implies that countries with high-income growth should be prioritized in export expansion, and raising an export price might be a good policy option. Research on global supply chains and price volatility is needed. In addition, this study results in formulating policies related to developing the cinnamon product industry and trade. Keywords: Cinnamomum sp., data regression, demand, export, function panel

Abstract

Paper and paperboard consistently contribute to Indonesia’s foreign exchange reserves with high export values. Research on demand and other economic analyses related to paper and paperboard products in Indonesia is insufficient. This paper focuses on Indonesian paper and paperboard competitiveness in international markets, especially in strengthening the Indonesian economy and supporting sustainable growth. Paper with Harmonized System Code 480256 is the largest proportion of Indonesia’s exported paper and is mostly exported to Japan. The import share of Indonesian paper in Japan’s market was approximately 69% from 2010 to 2023. Based on the Quadratic Almost Ideal Demand System (QUAIDS) model, the import demand of Indonesian paper was found to be elastic. Moreover, China and Indonesia papers were substitutes, whereas Indonesia and the United States papers were complementary. Expenditure elasticity analysis further showed that Indonesia’s paper was a normal good in Japan’s market. These results highlight the policy relevance for policymakers in designing and improving Indonesia’s forest products for international trade. Keywords: budget share, export, paper, price elasticity, QUAIDS

Abstract

Indonesia is one of the world’s leading exporters of uncoated paper products, supported by abundant plantation forests. However, Indonesia's uncoated paper export declined over the period 2018-2024. The objective of this research was to examine factors affecting the export competitiveness of Indonesia’s uncoated paper products in the global forest products market during and after the COVID-19 pandemic. Data on export values, exchange rates, and GDP deflators obtained from Trade Map and the IMF were analyzed using the Constant Market Share analysis.  The results showed that during the COVID-19 pandemic, Indonesia’s uncoated paper exports increased mainly due to favorable impacts on world trade and competitiveness. In contrast, the composition of commodities and market distribution had an unfavorable impact on Indonesia’s exports. After the COVID-19 pandemic (2023-2024), Indonesia’s uncoated paper exports declined due to adverse effects on global trade and a negative competitiveness effect. On the other hand, commodity composition and market distribution had a favorable impact on Indonesia's exports. For the future, Indonesia needs strategies to maintain and improve the competitiveness and market stability of HS 480256, HS 480255, and HS 480257, such as: ensuring the forest certification; maintaining sustainable production, periodically reviewing international trade barriers, tariff changes, production cost efficiency; and increasing the capacity and technology of paper products. To provide more insight, the CMS method should be combined with an econometric method that can directly model a structural change in demand and estimate important parameters, such as price, cross-price, and income elasticities. Keywords: competitiveness effect, composition effect, constant market share, market distribution effect, writing paper

Abstract

Although widely cultivated for wood production in Indonesia, studies on Eucalyptus leaf essential oils (ELEOs) from Eucalyptus clones remain limited. This study investigated the yield, phytochemical profiles, cytotoxic activities, and putative compounds associated with the cytotoxicity of ELEOs obtained from seven Eucalyptus clones cultivated in North Sumatra, Indonesia. The oils were extracted by water-and-steam distillation for 1.5 h, starting when the first oil droplet appeared. Phytochemical profiles were characterized by gas chromatography-mass spectrometry, and cytotoxicity against A549 lung cancer and B16-F10 murine melanoma cells was evaluated in vitro. Multivariate analyses, such as orthogonal partial least squares and principal component analysis, together with molecular docking, were used to identify compounds associated with cytotoxicity. Essential oil yield ranged from 0.15% to 0.39% (w/w), while eucalyptol, the principal quality marker of ELEO, ranged from 7.98% to 41.69% among the clones. The clone of Eucalyptus grandis x Eucalyptus open-pollinated clone (GOP) exhibited the lowest IC50 value for B16-F10 cells (165.3 microgram/mL), and the clone of E. urophylla x Eucalyptus open-pollinated clone (UOP1) exhibited the lowest IC50 value for A549 cells (111.9 microgram/mL). According to multivariate analyses and molecular docking, alpha-pinene, (-)-spathulenol, and (-)-globulol are compounds that likely exhibit cytotoxicity against B16-F10 cells, while gamma-terpinene, o-cymene, o-cymen-5-ol, and leptospermone are compounds that likely exhibit cytotoxicity against A549 cells. However, in normal cell lines, it was not possible to achieve cytotoxic selectivity, as the biological significance of the observed cytotoxic responses is not yet established. In general, the results indicated that the yield, phytochemical composition, and cytotoxic activity of ELEOs derived from Eucalyptus clones depend on the genetic background.

Abstract. Simangunsong BCH, Manurung EGT, Elias, Hutagaol MP, Tarigan J, Prabawa SB. 2020. Tangible economic value of non-timber forest products from peat swamp forest in Kampar, Indonesia. Biodiversitas 21: 5954-5960. Development of alternative economy based on non-timber forest products usage is an important means to prevent forest conversion and preserve the quality of a forest ecosystem. The main objectives of this study were to identify and calculate the economic value from tangible/marketable perspective of the non-timber forest products (NTFPs) provided by peat swamp forest in Kampar, Sumatra, Indonesia. This is one of the largest remaining peat swamp forest ecosystems in the country. Seven villages located around that forest ecosystem with total forest cover area of 201,224 ha were chosen as samples. A conversion return approach was used to estimate the economic value of non-timber forest products. The results showed 18 kinds of non-timber forest products were identified, but only seven were used commercially by community. They are jungle rubber (Hevea brasiliensis), sago (Metroxylon sp.), swiftlet nest (Aerodramus fuciphagus), honey, betel nut (Areca catechu L), Agathis resin (Agathis dammara), and pandan (Pandanus amaryllifolius Roxb.) The obtained economic value of NTFPs was very low, which was about Rp 9,367.4 (or US$0.68 ha-1 yr-1). Market development of non-timber forest products is then crucial, and the government should play an important role in promoting it in collaboration with private companies. Non-marketed non-timber forest products and various environmental services should also be taken into account to measure that peat swamp forest ecosystem value. Otherwise, concerns about the sustainability of that forest ecosystem in Indonesia due to undervaluation of forest resources will continue.

Abstract

Background: Indonesia is a tropical country with abundant forest resources, and plywood is a key value-added product. Among the globally traded plywood products, HS 441231 accounts for the largest share and is a strategic component of Indonesia’s exports. South Korea is one of Indonesia’s main export destinations, as imports largely satisfy its plywood demand. Although Indonesia maintains a dominant position, its exports to South Korea have declined in recent years amid competition from Malaysia and Vietnam. Given the high supplier concentration, understanding South Korea’s import demand structure is increasingly important.Purpose: This study analyzes the demand for Indonesian plywood (HS 441231) in the South Korean market using the LA/AIDS and QUAIDS models to assess price and expenditure responses and evaluate Indonesia’s position relative to major competitors.Design/methodology/approach: The analysis uses monthly South Korean import data for HS 441231 from 2010 to 2024. LA/AIDS and QUAIDS models are estimated using SUR and NLSUR with adding-up, homogeneity, and symmetry restrictions.Findings/Result: Indonesian plywood holds the largest import share, shows elastic demand, and functions as a normal good. The quadratic component of the QUAIDS is significant, indicating a nonlinear consumption pattern. Indonesia has a substitution relationship with Malaysia and a complementary relationship with Vietnam.Conclusion: Indonesia’s competitiveness in the South Korean market is primarily price-based, indicating the need for greater cost efficiency, enhanced quality, and compliance with certification requirements to achieve a more sustainable position.Originality/value (State of the art): This study contributes to the literature by combining LA/AIDS and QUAIDS to analyze South Korea’s plywood demand, providing empirical insights into cross-country substitution dynamics. Keywords: elasticity, expenditure share, import competition, LA/AIDS, QUAIDS
