1.   Introduction

Non-Timber Forest Products (NTFPs) are forest resources with advantages and proven ability to contribute to community welfare by increasing income while maintaining forest sustainability (Abate et al., 2025). Utilization of NTFPs typically does not damage forest stands, making them an alternative for sustainable forest management. Therefore, NTFP development not only supports community economic development but also aligns with environmental conservation goals (Sarria et al., 2021), (Atinga & Bannor, 2024). NTFPs play a strategic role in improving the welfare of communities surrounding forests. Many communities depend on these forest products for their livelihoods, both for daily use and for sale (Harbi et al., 2023). With proper management, NTFPs can provide a sustainable source of income for communities without the need for excessive tree felling (Beck et al., 2023). Therefore, wise NTFPs management is key to achieving a balance between economic and ecological interests.

Indonesia's NTFPs potential is immense due to its vast tropical forests and diverse plant species. Nearly every region boasts its own distinctive NTFPs commodity. This diversity makes NTFPs a viable sector for development to boost regional economies while strengthening local identity (Adaaja et al., 2024). Within the context of sustainable development, NTFPs can play a crucial role in supporting the achievement of sustainable development goals (SDGs), particularly in the economic, environmental, and social sectors (Mohale et al., 2025). Properly managed NTFP utilization can create new jobs, increase community incomes, and encourage local resource-based small and medium enterprises (SMEs) (Akomaning et al., 2023). Furthermore, NTFPs can also strengthen local wisdom, as many of them are used in traditions, traditional medicines, and cultural activities of communities surrounding forests (Dako et al., 2024).

One of the non-timber forest products (NTFPs) widely managed and developed by communities surrounding forests is pine resin. Pine resin is a NTFP with high economic value and is widely used in various industries (Zakiyah et al., 2025). This resin is obtained through a tapping process on pine tree trunks. The resulting resin is then collected, collected, and further processed. In general, pine resin consists of two main components: gondorukem (solid resin) and turpentine (liquid resin), both of which have broad uses. Gondorukem is widely used in the paper, paint, adhesive, soap, printing ink, and cosmetics industries, while turpentine is used as a solvent, perfume mixture, and medicine. The pine resin tapping process requires proper techniques to avoid damaging the tree trunk and to ensure sustainable resin production.

Sustainable pine resin tapping is not only financially profitable but also helps preserve the environment. This activity encourages communities to refrain from indiscriminate tree felling, as the economic value of the resin is greater if the trees remain standing. Therefore, pine resin management is considered an example of environmentally friendly forest utilization practices, supporting the concept of sustainable development, while strengthening social and institutional aspects of the community (Moura et al., 2023) and (Oliveira et al., 2023).

Industrially, pine resin offers significant development opportunities in Indonesia, given the ever-increasing market demand, both domestically and internationally. Indonesia is one of the world's largest pine resin producers, thus offering significant potential to become a major player in the gondorukem and turpentine trade. However, realizing this potential requires improving production quality through the implementation of more modern tapping technologies, improving processing systems, and opening wider market access. If these aspects can be optimized, pine resin will become not only a local commodity but also a leading national commodity capable of increasing the country's foreign exchange (Tsioras, 2023).

Sasakan Village, Mamasa Regency, is one of the areas with the largest pine resin potential in West Sulawesi Province. In this village, the utilization of pine resin is an important alternative source of income for the village community. The pine forest area in this village is quite extensive, so the local community relies heavily on resin tapping as a supplementary livelihood besides farming. The collected pine resin is usually sold to collectors or processing industries, who then convert it into value-added products.

However, the sustainability of this business depends heavily on the efficiency of the supply chain. Although pine resin tapping technically adds value, the community often faces price uncertainty and unequal value distribution. Therefore, analyzing marketing margins and profit margins is crucial. Without a thorough understanding of these margins, it is difficult to determine whether the generated economic value is truly distributed fairly to tappers at the grassroots level or is instead trapped in the intermediary chain. This analysis is crucial for identifying market inefficiencies, optimizing real community incomes, and ensuring that economic incentives remain strong enough to motivate residents to maintain the long-term sustainability of the pine forests.


2.   Materials and Method

1)   Research Location

This research was conducted in Sasakan Village, Sumarorong Subdistrict, Mamasa Regency, West Sulawesi Province. The location was chosen based on the abundant potential of pine resin in this village, as it is one of the region's leading non-timber forest products. PT Kencana Hijau Bina Lestari in Polewali Mandar Regency is also a business operator in the pine resin industry.


2)   Types and Sources of Data

The data collected in this study consists of primary and secondary data. Primary data was obtained from in-depth interviews with respondents, namely farmers who actively tap pine resin in Sasakan Village, interviews with partners, and joint interviews with PT KHBL (Kencana Hijau Bina Lestari). Primary data included prices and costs needed to calculate margin indicators. Meanwhile, secondary data was obtained from literature studies sourced from articles or other sources relevant to the research and also obtained from data available at relevant agencies. The secondary data collected included data on the general conditions of the research location and other necessary secondary data.


3)   Sampling Technique

The population in this study was the community in Sasakan Village, Sumarorong Subdistrict, Mamasa Regency, West Sulawesi Province, which has pine trees. Total farmers actively tapping pine resin is 33 people, therefore census was used. The criteria for respondents used in this study were farmers who actively tapped pine resin and were involved in the pine resin business. In addition to farmers, this study also involved partners who collect pine resin from farmers, as well as representatives from PT KHBL (Kencana Hijau Bina Lestari).


4)   Data Collection Techniques

Data collection techniques in this study were carried out in the following ways:


5)   Data Analysis

The data analysis used in this study is quantitative analysis in the form of data obtained in the form of numbers that can be calculated, in this case the calculation of marketing margins and profit margins. The allocation of production costs is based on the proportion of output (yield) from the pine resin processing process, namely 75% producing gondorukem and 25% producing turpentine. This approach refers to the joint cost allocation method based on physical output, which is commonly used in the forestry product processing industry and agro-industry. The formula used in the margin calculation is as follows:

The margin calculation for each marketing agency uses the following formula (Su’udi, 2018):

𝐌𝐩=𝐏𝐫𝐏𝐟𝐨𝐫𝐌𝐩=𝐁𝐩+𝐊𝐩\mathbf{Mp\ = \ Pr\ - \ Pf\ or\ Mp\ = \ Bp\ + \ Kp}

Description:

Mp = Marketing Margin (IDR/kg)

Pr = Consumer prices (IDR/kg)

Pf = Price at producer level (IDR/kg)

Bp = Marketing costs (IDR/kg)

Kp = Profit (IDR/kg)

The profit margin calculation for each business operator uses the following formula (Pratama, 2018):

𝛑=𝐏𝐚𝐏𝐛𝐂\mathbf{\pi\ = \ Pa\ - \ Pb\ - \ C}

Description:

Π = Profit Received by Each Actor

Pa = Selling price for each actor (IDR)

Pb = Purchase price of the product for each actor (IDR)

C = Marketing costs for each actor (IDR)


3.   Result and Discussion

1)   Marketing Channels

The marketing channel of pine resin in Sasakan Village illustrates the flow of products and value from upstream producers to downstream consumers, involving multiple actors with distinct roles in the supply chain. As shown in Figure 1, the marketing system consists of three main actors: farmers as primary producers, partners as intermediaries, and the processing industry (PT KHBL) as the downstream actor that transforms raw pine resin into higher-value products before reaching final consumers.

This structure reflects a typical value chain of non-timber forest products (NTFPs), where raw materials produced at the local level are gradually transferred through several stages of aggregation, processing, and distribution. The existence of multiple marketing channels indicates variations in the flow of products, which may influence both the efficiency of the supply chain and the distribution of economic benefits among actors. Understanding this marketing structure is essential for identifying how value is created and distributed along the chain, as well as for analyzing the differences in marketing margins and profit margins observed among actors in subsequent sections.

Figure 1. Pine resin Marketing Channel

2)   Marketing Margin

Marketing margins indicate the difference between the selling price and the purchase price for each business actor (Cannon & Morgan, 2013). The results of the study indicate that the largest margin is at the third marketing channel level, namely the pine resin processing industry (PT KHBL), because it has processed pine resin into two types of final products, namely gondorukem and turpentine. The high marketing margin on an industrial scale is due to several factors, including the use of modern technology/equipment that can reduce raw material waste. PT KHBL processes on a large scale so that production costs per unit are lower, and not only processes but also secures direct supplies from pine resin tappers, in addition to the process also minimizes intermediaries.

The marketing margin of the final pine resin product in the form of gondorukem shows that in marketing channel I, the selling price at the farmer level is IDR 10,000/kg and is directly sold to partners. Marketing channel II shows the selling price to partners is IDR 12,000/kg and the partner's purchase price from farmers is IDR 10,000/kg so that the partner's marketing margin is IDR 2,000/kg. Marketing channel III shows the processing of pine resin into products and the price of gondorukem sold to consumers is IDR 25,000/kg so that the marketing margin is IDR 13,000/kg. The marketing margin data for gondorukem is presented in Table 1.

The marketing margin for the final pine resin product, turpentine, shows that in marketing channel I, the selling price at the farmer level remains at IDR 10,000/kg and is sold directly to partners. Marketing channel II shows that the selling price to partners then increases to IDR 12,000/kg, resulting in a partner marketing margin of IDR 2,000/kg. Marketing channel III shows that raw materials are processed into turpentine products, and the price of turpentine sold to consumers is IDR 75,000/kg, resulting in a marketing margin of IDR 63,000/kg. The turpentine marketing margin data is presented in Table 2.

3)   Costs for Each Marketing Channel

To ensure consistency between aggregate costs and unit margin analysis, all costs presented in total (monthly or per production) are converted to a cost per kilogram by dividing the total cost by the total production volume (kg). This approach is used for all actors in the marketing chain, ensuring that marketing margin and profit margin calculations are comparable across actors.

Based on field studies, in marketing channel I at the farmer level, no labor is involved in any of the pine resin processing processes, including tapping, pouring the resin into containers, or delivering it to partners. This is because each process is not particularly difficult and the amount of production produced in a single production run is inconsistent, meaning that whatever quantity of pine resin is collected, that amount is delivered to partners, thus eliminating the need for labor. Pine resin tapping farmers stated that family members usually assist them in each harvesting process, thus eliminating labor costs. This, of course, can help reduce costs during the pine resin harvesting process, which will affect profits (Khotimah et al., 2025).

The costs incurred in marketing channel II, namely Partners, are in the form of the cost of providing stimulants consisting of nitric acid at a price of IDR 21,000/kg, sulfuric acid IDR 27,000/kg and salt IDR 10,500/kg, then the cost of providing pine resin tapping equipment consisting of a resin bowl at a price of IDR 8,800/piece, a sap flow gutter IDR 250/piece, a hoe IDR 85,000/piece, a plastic sap container IDR 14,000/piece and a sap container sack IDR 1,300/piece, then the cost of transportation by partners to PT. KHBL Site Mamasa to store pine resin before being transported to PT. KHBL Site Polewali Mandar as a processing industry with a total transportation cost of IDR 1,500,000/month. So that the total cost incurred by partners is IDR 158,405,400. The total volume of pine resin marketed by partners is assumed to be equivalent to the raw material capacity received by the industry, which is 169,000 kg of pine resin per production cycle, resulting in a cost to partners of IDR 937/kg. Partner costs are presented in Table 3

The first cost incurred in marketing channel III, namely the pine resin processing industry, is the marketing cost of exporting gondorukem and turpentine to the domestic market and consumer countries by exporting seven containers each month. One shipment contains 109 tons of gondorukem and also 60 tons of turpentine, so in one shipment, PT KHBL incurs marketing costs through port agent services with a total of seven containers, amounting to IDR 139,200,000. The marketing costs incurred by PT KHBL are presented in Table 4.

PT KHBL's labor costs, which employ approximately 100 employees, are paid IDR 3,104,430 per month in Polewali Mandar Regency, resulting in total labor costs of IDR 310,443,000 per month.

The total cost incurred by PT KHBL, including marketing costs, equipment depreciation costs, and labor costs, is IDR 458,495,236. This total represents the aggregate cost for one production cycle that processes 169,000 kg of pine resin. For margin analysis purposes, this cost is converted to a cost per kilogram using the following calculation:

IDR458,495,236:169,000kg=IDR2,712/kgIDR\ 458,\ 495,236\ :\ 169,000\ kg\ = \ IDR\ 2,712/kg

Based on the analysis, it is known that in a single production process of gondorukem and turpentine, which requires 169,000 kg of pine resin, the cost allocation was carried out using a physical output-based joint cost allocation approach, which produces 75% gondorukem namely 126,750 kg and 25% turpentine namely 42,250 kg in a single production run. Therefore, the cost per kg for each product is calculated as follows:

Cost of gondorukem per kg = (75% × total cost) / total gondorukem output

Cost of turpentine per kg = (25% × total cost) / total turpentine output

This approach allows for a clear link between aggregate production costs and the calculation of margins per unit. Therefore, the cost for each product, gondorukem and turpentine, is equal to IDR 2,712/kg.


4)   Profit Margin

Profit margin represents the difference between the selling price and the purchase price, minus the total costs for each product sold (Silva, 2026). The study found that the largest profit margins were found at the third level of the marketing channel, namely wholesalers, in this case PT KHBL Site Polewali Mandar. This is due to their role as downstream players processing raw materials into high-value products, supported by production scale efficiencies, access to export markets, and a stronger bargaining position within the market structure. This situation results in the majority of added value in the pine resin supply chain being concentrated at the industrial level, which has marketed within the domestic market reach of Pasuruan City, Bekasi, and Bogor, as well as international markets including India, Japan, China, and Korea.

The profit margin for the final pine resin product, gondorukem, shows that in marketing channel I, the selling price to the farmer is IDR 10,000/kg, with no costs incurred, resulting in a profit margin of IDR 10,000/kg. Marketing channel II shows a selling price to partners of IDR 12,000/kg with costs incurred of IDR 937/kg so that the partner's profit margin is IDR 1,063/kg. Marketing channel III shows a selling price of gondorukem of IDR 25,000/kg with a total cost of IDR 2,712/kg so that the profit margin is IDR 10,288/kg. Gondorukem profit margin data is presented in Table 6.

The profit margin of the final product of pine resin in the form of turpentine shows that in marketing channel I, the selling price at the farmer level remains at IDR 10,000/kg and does not incur costs so that the farmer's profit margin is IDR 10,000/kg. Marketing channel II shows a selling price to partners of IDR 12,000/kg with costs incurred of IDR 937/kg so that the partner's profit margin is IDR 1,063/kg. Marketing channel III shows a turpentine selling price of IDR 75,000/kg with a total cost of IDR 2,712/kg so that the profit margin is IDR 60,288/kg.

4.   Conclusion

This study demonstrates that the pine resin value chain in rural Indonesia is characterised by clear unequal value capture across actors. While farmers, partners, and the processing industry are structurally connected within the marketing system, the majority of economic value is concentrated at the downstream industrial level. This is particularly evident in the processing of turpentine, where both marketing and profit margins are substantially higher compared to upstream actors.

These findings indicate that unequal value capture is not merely a result of price differences, but reflects structural conditions within the value chain, including differences in processing capacity, access to technology, market reach, and bargaining power. As a result, upstream actors, particularly farmers, receive a relatively small share of the total economic benefits despite their central role in production.

This pattern highlights the presence of inefficiencies and imbalances in the pine resin marketing system, which may weaken long-term incentives for sustainable forest-based livelihoods. Addressing this issue requires strengthening farmer bargaining power, improving access to processing technologies at the local level, and promoting more inclusive market linkages. Enhancing equity in value capture is essential not only for improving rural incomes but also for supporting the sustainability of non-timber forest product-based systems.
