Abstract

Background: To combat environmental degradation and resource scarcity, a global shift from a linear to a circular economy is necessary. Kefir production offers significant potential for the circular economy by leveraging by-products such as whey and ricotta. Objective: This study describes the application of circular economy concepts within a kefir microenterprise in Samarinda, Indonesia, focusing on waste-recycling practices, profitability patterns, and sustainable business strategies. Method: A mixed-method approach combining digital ethnography, e-commerce data analysis, and indirect cost calculation was used to identify circular processes and their association with production costs. Results: Local producers have successfully transformed waste into functional foods and cosmetics. This study demonstrates that these producers naturally apply circular economy principles through practical experience. Converting by‑products into revenue streams helps offset the low profit margins of basic products, given the large gap between market prices and production costs. Conclusion: The growth and resilience of micro, small, and medium enterprises (MSMEs) in the kefir sector align with sustainability concepts. This article suggests strengthening value chain integration and encouraging greater collaboration among stakeholders to make the transition to a circular model more effective. Keywords: dairy product; fermented product; green economy; sustainability; waste valorization

Abstract

Stingless bee honey agribusiness supports sustainable rural development and food security. Small-scale producers in Indonesia face challenges such as limited production capacity, weak branding, and low technological adoption. These barriers reduce their competitiveness in a rapidly expanding natural and functional food product market. This study aims to formulate strategies to enhance the competitiveness of stingless bee honey agribusiness through marketing innovation and product downstreaming in Lempake Village, Samarinda, East Kalimantan. Using a descriptive qualitative approach supported by SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis, this research identifies key internal and external factors influencing business performance. The results show that the kelulut honey agribusiness is positioned in the progressive strategic quadrant (Quadrant I), with strong internal resources and favourable market opportunities. The main strengths lie in high product quality, sustainable local resources, and active farmer institutions, while weaknesses include limited technological capacity and low digital marketing literacy. Opportunities arise from the increasing demand for natural products and government support for downstreaming, whereas threats stem from market competition and fluctuating supply conditions. Strategic recommendations include strengthening digital branding, enhancing post-harvest and processing technology, fostering institutional collaboration, and promoting product diversification to increase added value. These strategies are expected to reinforce local competitiveness, promote sustainable agribusiness growth, and contribute to Indonesia’s long-term food security.

Abstract

There are chances for small and medium-sized businesses (SMEs) to boost local agricultural economies and increase profitability due to the rising demand for value-added dairy products.  This study uses the Hayami approach to evaluate the value distribution along the production chain in order to investigate the economic potential of cream cheese production in Samarinda, Indonesia.  In-depth producer interviews, cost documentation, questionnaires, and production process observations were used to gather primary data.  Identifying the main cost components and evaluating value generation at the processing step were the main objectives of the investigation.  The results show that processing adds a substantial amount to the total product value, with the acquisition of raw materials and packaging being the main sources of expense. Maximizing by-products like whey, implementing cost-effective packaging, and optimizing input sourcing are all ways to boost profitability. According to the report, local cream cheese makers can become more resilient and competitive by focusing on specialized markets, improving branding, and fortifying supply chain integration. These observations serve as the foundation for business plans and regulatory suggestions meant to promote long-term expansion in the artisanal dairy industry.

Abstract

The purpose of this study is to assess the sensitivity of broiler chicken producers' income to fluctuations in live chicken selling prices and feed costs in Samarinda City. The research was conducted using a simulation approach under several scenarios of price and cost adjustments, ranging from - 20% to + 20% of the base value. The findings show that changes in selling prices had a more linear influence on income, with a 10% increase in live chicken prices increasing revenue by about 13%. Feed expenses, on the other hand, have a more unequal effect on revenue, particularly as costs grow, resulting in significant profit margin reduction. These findings imply that farmers' income is extremely vulnerable to external market dynamics, both in terms of income and production costs. This study validates earlier research findings published in international journals, emphasizing the necessity of risk mitigation methods and cost efficiency as critical variables for the long-term viability of small- and medium-sized poultry farming operations. As a result, governmental measures are required to safeguard farmers from volatility in both input and product prices.

Abstract

Degraded post-mining lands in East Kalimantan suffer from low soil fertility, reduced biodiversity, and limited economic value for local communities. Previous efforts, such as monoculture reforestation or single-sector agriculture, have produced limited ecological recovery and economic resilience. This study aims to develop a community-based sustainable business model and assess the ecological and economic impacts of an integrated cattle–forage–stingless bee system in post-mining regions. A mixed-methods approach combined qualitative techniques (in-depth interviews, focus group discussions) with quantitative analyses (carbon footprint, R/C ratio, B/C ratio) across five regencies, involving five key informants and thirty farmers. The system advances SDGs by increasing income through diversified products (SDGs 1, 2, 8), converting degraded land into carbon sinks (-12.05 tCO₂e/ha/year) (SDGs 13, 15), and supporting biodiversity through pollination (SDG 15). Its cyclical approach, aligned with SDG 12, transforms wastelands into sustainable agricultural landscapes, addressing climate and livelihood challenges. This is the first empirical study to link carbon sequestration and biodiversity gains with economic viability in a three-tier cattle–forage–stingless bee integration for post-mining landscapes.
