The demand for rubber continues to rise in countries with established automotive industries. However, the potential of Indonesia’s rubber as an export commodity, along with its domestic absorption, has not yet matched the opportunities available in the international rubber market. This discrepancy, reflected in the decline in both value and volume of Indonesian rubber exports over recent years, poses a threat if left unaddressed. This study aims to analyze the competitiveness of Indonesian rubber exports to destination countries and to examine Indonesia’s market position and export potential in those countries. The data utilized in this research consist of Indonesia’s rubber export values, which are analyzed using the Revealed Comparative Advantage (RCA), Export Product Dynamics (EPD), and the X-Model of Product Export Potential. The findings indicate that rubber is a commodity with a strong comparative advantage, supported by Indonesia’s natural endowments, affirming its role as a key rubber-exporting country in the global market. Furthermore, the development of rubber export markets in importing countries demonstrates promising potential.

Sugarcane farmers face the persistent issue of information asymmetry, an imbalance of knowledge between farmers and sugar mills that disrupts transparency and undermines trust within the supply chain. In addition, a high dependency on intermediaries and limited access to financing further exacerbates the economic disparity experienced by farmers. Investigating cost structures, information asymmetry, and partnership models within the sugarcane supply chain is therefore essential. This study was conducted in 2024 in Jember Regency, East Java. The methods employed include cost structure analysis, identification of information asymmetry, and estimation of sugar mill production potential. The findings reveal that sugarcane cultivation in Jember is predominantly organized under two partnership schemes: the Revenue-Sharing System (Sistem Bagi Hasil/SBH) and the Sugarcane Purchase System (Sistem Pembelian Tebu/SPT). Information asymmetry remains a major challenge, as farmers heavily rely on sugar mills as their primary source of information (78.4%), thereby diminishing their bargaining power. Despite being financially profitable (with an average income of IDR 24.4 million per hectare), the cost structure is largely concentrated in labor (59.24%) and fertilizers (20.56%). Market transaction costs account for 87.1% of total expenditures, indicating significant inefficiencies within the supply chain. An analysis of sugar mill capacity shows considerable variation in production scale; however, sugarcane supply remains unstable as farmers tend to sell to mills offering higher prices. Strengthening farmer groups, improving market information transparency, implementing integrated planting coordination, and fostering more equitable partnership models are all critical measures to ensure supply chain stability and enhance farmer welfare.

Magetan Regency is one of the producers of robusta coffee known for its strong flavor and aroma, making it highly promising for export markets. However, marketing efforts and farmer interest remain low, primarily due to the perennial nature of the plant, which is perceived as less favorable for rapid capital turnover. Therefore, this study aims to assess the marketing efficiency of robusta coffee in Magetan so that farm-gate prices can become more attractive and competitive in export markets. The study employed a descriptive method with a survey research technique. A purposive method was used to determine the research location, as Magetan is recognized for producing high-quality and diverse coffee varieties. Panekan and Poncol sub-districts were selected due to their status as the largest coffee-producing areas. Farmer respondents were selected using purposive sampling, consisting of coffee farmers from two farmer groups in the respective sub-districts, where all members cultivate coffee. The snowball sampling method was employed to identify institutions involved in the marketing channels. The findings reveal that the coffee marketing institutions in Magetan Regency consist of farmers, collecting traders, retail traders, and out-of-town traders. The marketing pattern of robusta coffee in the region is categorized into three distinct channels. Overall, the marketing system for robusta coffee remains inefficient. However, Marketing Channel II has been identified as the most efficient and thus holds potential for entering export markets.

The phenomenon of urban sprawl in Bogor City has led to land-use changes and the expansion of residential areas, resulting in the reduction of green and agricultural lands that function as ecological buffers and providers of urban landscape services. KWT (Kelompok Wanita Tani or Women Farmer Groups) Gardens represent existing Green Open Spaces (Ruang Terbuka Hijau/RTH) in Bogor City that adopt a mixed garden or agroforestry system. This study aims to analyze the contribution of KWT gardens to plant biodiversity and carbon stock in Bogor City as a means of enhancing urban landscape services. Data were collected from six KWT gardens located in six districts across Bogor City. Plant composition and carbon stock data were obtained through field inventory and analyzed using a web-based tool, MyTree. The results show that vertically, the plant composition in KWT gardens is dominated by Stratum I vegetation (0–1 m) at 87.95%, while horizontally, the gardens are dominated by vegetable crops, accounting for 42.63% of the total. The highest tree carbon stock was found in KWT MM at 928.49 kg on a land area of 0.14 ha, while the lowest was in KWT AZ at 233.08 kg on a land area of 0.06 ha. KWT gardens using agroforestry systems contribute to enhancing plant biodiversity and carbon storage, which benefit urban communities both directly and indirectly.

This study is grounded in the increasing public awareness of healthy lifestyles in the post-pandemic era. On the other hand, social media platforms such as Instagram hold significant potential in influencing consumer behavior toward healthy products. However, the sales of Kaldu Tempe have shown a substantial decline despite its alignment with healthy lifestyle values. This study aims to: (1) identify the consumer characteristics of Kaldu Tempe Pawon Ibun; (2) analyze the relationship between healthy lifestyle and social media marketing on the purchase decision of Kaldu Tempe Pawon Ibun; and (3) examine the mediating role of purchase intention in the relationship between healthy lifestyle and social media marketing on the purchase decision of Kaldu Tempe Pawon Ibun. The research employed a quantitative explanatory approach with a sample size of 100 respondents. Descriptive statistics were used to address the first objective, while Structural Equation Modeling with Partial Least Squares (SEM-PLS) using SmartPLS 4 software was utilized to address the second and third objectives. The results indicate that adopting a healthy lifestyle significantly influences purchase decisions, both directly and indirectly through purchase intention. Social media marketing plays a critical role in fostering purchase intention, which in turn affects consumer decision-making, even though it does not have a direct impact on the purchase itself. These findings underscore the crucial role of purchase intention as a bridge between promotional efforts and consumer actions. This study provides strategic implications for micro, small, and medium enterprises (MSMEs) in designing promotional content that aligns with healthy lifestyle values to enhance consumer purchase intention and decisions.

Agroforestry is a sustainable land-use approach that offers both ecological and economic benefits, including for strategic commodities such as Muntok White Pepper in Central Bangka Regency. However, the adoption rate of agroforestry among pepper farmers remains suboptimal, partly due to psychological factors. This study aims to analyze the psychological determinants of farmers' intentions to implement agroforestry using the Theory of Planned Behavior (TPB) framework, which includes three main constructs: attitude toward behavior, subjective norms, and perceived behavioral control. The study was conducted with an explanatory quantitative approach to 105 purposively selected white pepper farmers in Namang and Simpang Katis Districts. Data were collected through a structured questionnaire and analysed using multiple linear regression. The results of the analysis showed that attitudes towards behaviour and perception of behaviour control had a significant effect on farmers' intention to adopt agroforestry, while subjective norms did not have a significant effect. Attitude emerged as the most dominant predictor, highlighting the importance of farmers’ positive perceptions of agroforestry’s benefits. These findings strengthen the applicability of TPB in agroforestry adoption research and provide policy implications for developing behavior-based extension strategies. Policy recommendations should focus on strengthening farmers’ capacity and perceived ability rather than social pressure to enhance agroforestry implementation in white pepper farming systems.

Variations in land ownership status, such as self-owned land, rental farming, and profit-sharing system, are believed to influence the productivity of rice farming. In Kulon Progo Regency, the shrinking agricultural land area due to infrastructure development, rising price of farm land’s rent, along with an increasing number of farmers without land’s ownership, highlights the urgency of examining the effectiveness of the profit-sharing system. However, empirical evidence regarding its impact on productivity remains limited. This research is aimed to study whether the profit-sharing system achieves similar productivity levels compared to self-owned or rented land. In this research, proportional stratified random sampling is utilized as the main method of acquiring data samples. There are 92 respondents studied in this research. Descriptive quantitative analysis and double linear regression analysis of Cobb-Douglas production function were employed as methods of analysis in this study. The result showed there was no difference in level of productivity between self-owned land farming and rental farming. Fertilizer use and farming experience were found as factors that increase productivity in rice farming, while land area and labor were found as factors that decrease productivity. These findings support Cheung’s theory, which asserts that there is no difference in productivity between profit-sharing and fixed-rent systems. Moreover, the results offer practical insights, suggesting that non-ownership land management, such as rental and profit-sharing, can serve as viable alternatives to improve land accessibility in the agricultural sector, particularly for young farmers.

Malang City experiences an increase in population every year, which has led to a reduction in agricultural land. In addition, the population continues to grow due to the arrival of newcomers and students from outside the city. Despite having a high population, there is still unused agricultural land that has not been optimally utilized. These areas have transitioned to urban farming by using the land to produce healthy vegetables. This study aims to analyze the factors influencing interest in agriculture, such as knowledge, attitude, and perception. A quantitative approach was used in this research, employing purposive sampling techniques, including interviews and documentation. The total sample size in this study was 70 respondents. Data processing was conducted using descriptive statistical analysis and SEM-PLS. The results of the study indicate that knowledge and attitude toward urban agriculture do not have a significant effect on people’s interest in farming in urban areas. However, perception of urban agriculture has a positive influence on interest, as the community recognizes its economic, social, and environmental benefits.

The potential of fishery resources around the Mandalika Special Economic Zone (KEK) has not been optimally utilized. This region possesses significant potential in aquaculture commodities that can support both industry and tourism. The selection of commodities should be based on the comparative advantages of each area to enhance productivity and sustainability of resources. The objective of this research is to identify the leading aquaculture commodities in the vicinity of the Mandalika Special Economic Zone in Central Lombok Regency. This study employs a descriptive approach. Data collection was conducted using survey techniques through interviews with 30 respondents selected via purposive sampling. Data analysis utilized Location Quotient (LQ) analysis and Analytical Hierarchy Process (AHP). The results indicate that the leading aquaculture commodities around the Mandalika Special Economic Zone include marine and pond aquaculture commodities, which are prominent in one district, while pond fishery commodities are identified as leading in all districts except for Pujut District. Cage fishery commodities are leading in two districts, and rice-fish farming is leading in eight districts. The priority leading marine aquaculture commodities are seaweed, lobster, pearls, and grouper. The priority leading freshwater aquaculture commodities are tilapia, catfish, gourami, and goldfish. Additionally, the priority leading brackish water aquaculture commodities are vannamei shrimp, tiger shrimp, and milkfish. These findings can serve as a foundation for determining policies in the planning and development for sustainable fisheries around the Mandalika Special Economic Zone.
