The purpose of this paper is to assess whether the national program on beef self sufficiency could be achieved at 2014. A dynamic system model with Vensim computer program is applied. The model validated by Mean Absolute Percentage Error. The results shows high accuracies of the model. The assessment show that, first, the beef self sufficiency would not be achieved at 2014 if the program are treated and running as usual (Scenario I). Second, the beef self sufficiency would be achieved at 2015 if government increase the cow population by reducing the slaughter of local cows and expanding the cross breeding program through artificial insemination (Scenario II). Third, the beef self sufficiency would not be achieved at 2014 if the actual beef consumption are higher than the supply that produce through Scenario II (Scenario III). Another innovative solution for increasing local cow population is needed.

Indonesia's pepper growth rate tends to decrease compared to the growth rate of world pepper demand. This is due to the decline in production in Indonesia in recent years. This has an impact on the amount offered by Indonesia to meet the needs of the world. Indonesia's inability to compete with other countries makes Indonesia's position in taking on the growth of the world's hopes can be used by other countries. This situation can change Indonesia's position and competitiveness in trade on the international market. This study aims to analyze the level of competition between countries by using Revealed Comparative Auntungan (RCA and Dynamics Revealed Comparative Advantage (DRCA). The results of the study show that during the 2011-2013 period the highest increase in competitiveness between countries during the other period was an increase Significant exports to the countries of Brazil, India and Pakistan which increased on the value of RCA. Delaying in the 2011-2013 and 2014-2016 periods was related to increasing countries increasing exports such as Indonesia, Brazil and India. Position of Indonesia in 2016 Enlarging free markets greater than the results of world exports, Indonesia must increase the country's competitiveness.

Background: Highlight the importance of emphasizing the necessity of utilizing environmentally benign packaging materials, particularly given the mounting environmental concerns primarily attributed to the alarming rate of plastic waste production. Purpose: The study aims to analyze the factors that influence Generation Z consumers’ intention to purchase products with eco-friendly packaging and identify strategies that can be employed to enhance this intention. Design/methodology/approach: A path analysis was performed using Partial Least Square with Structural Equation Modeling (PLS-SEM).Findings/Result: The research findings indicate that environmental concerns, support for the policy, perceived behavioral control, attitude, and subjective norm positively and significantly influence the increased intention to purchase Generation Z products with eco-friendly packaging. Environmental concern and perceived behavioral control are pivotal in fostering increased purchase intention for these products. Environmental concerns strongly influence intentions to purchase eco-friendly packaged products, leading Generation Z to demand more. This phenomenon reflects consumer trends; stakeholders need involvement to encourage sustainable actions and achieve environmental sustainability, especially among young people. Conclusion: It could be concluded that environmental concern plays a pivotal role in Generation Z's intention to purchase products with eco-friendly packaging. This concern influences various aspects of the Theory of Planned Behavior, guiding consumers toward more sustainable choices. The findings indicate that a higher level of environmental concern is associated with a greater intention to select eco-friendly packaging. Therefore, stakeholders must enhance environmental awareness among Generation Z, as they will play a pivotal role in the future of environmental sustainability development. Integrating eco-friendly practices into campus environments and business strategies will help meet this demand and support the shift toward more sustainable consumer behavior.Originality/value (State of the art): This study uses an extended variant of the TPB with a research focus different from previous studies. Previous empirical studies such as Paul et al. (2016), Chaudhary & Bisai (2018), and Asih et al. (2020) focused on green products. In contrast, this study focuses on products with eco-friendly packaging. Paul et al. (2016) integrated the TPB model with environmental concern to examine its influence on purchase intention of green products in India, while Chaudhary & Bisai (2018) combined the TPB model with environmental concern to examine its influence on purchase intention and willingness to pay premium, and tested the moderation effect between purchase intention and green purchasing behavior in India. Asih et al. (2020) integrated the TPB model with environmental concern and environmental knowledge to examine interest in using green products. However, this study integrates environmental concern and policy to support the TPB model, examine the factors influencing Generation Z’s purchase intention toward products with eco-friendly packaging, and identify strategies to increase Generation Z’s intention to purchase. Keywords: environmental concern, green products, purchase intention, PLS-SEM, theory of planned behavior

This research aimed to analyze the transaction cost structure and the effect of transaction costs on the revenue and profit of red chili farming. The analytical methods used were Transaction Cost Economic (TCE) analysis and multiple regression analysis. This research was conducted in Garut Regency, West Java, on 145 farm households. The research results showed that the highest percentage of transaction cost components was at implementation costs of 25.1 percent, followed by information search costs of 23.1 percent and negotiation costs of 22.3 percent. The number of transaction costs formed in red chili farming was IDR 3,990 727.74 per year. The ratio of transaction costs to total costs was 0.0285. This indicated that farmers had to issue 2.85 percent of the total costs for transaction costs. In addition, the percentages of transaction costs for revenue and profit of red chili farming were 4.65 and 5.27 percent respectively. The results also showed that five variables had significant effects on the benefits of red chili farming. The five variables included the price of chili seeds, manure, insecticides, labor wages, and transaction costs.

This research analyzes marketing efficiency: marketing, marketing function, marketing margin, farmer's share, and the ratio of profit to cost of fresh fruit bunches (FFB) for ISPO (Indonesian Sustainable Palm Oil) and non-ISPO palm oil in Batanghari Regency, Jambi Province. The sample consisted of 30 ISPO farmers and 30 non-ISPO farmers, sampling farmers using a purposive method and then using the snowball sampling method to find out what institutions are involved in the ISPO and non-ISPO independent oil palm marketing process in Batanghari Regency. The research results show four marketing channels: (1) farmer-trader-large trader-palm oil weighing-mill, (2) farmer-trader-palm palm weighing-mill, (3) farmer-palm palm weighing-mill, and (4) farmer-merchant-mill. ISPO farmers do not experience differences in marketing channels and prices, which is not in accordance with the objectives of establishing ISPO. Marketing functions include purchasing, selling, transporting, harvesting, risk-bearing, financing, and market information. Analysis of marketing margin, farmer's share, and profit-to-cost ratio shows the third most efficient channel with a farmer's share of 87.82% with the farmer's marketing channel selling FFB through palm oil weighing, which distributes it to mills, involving one marketing institution.
