The consistent decline in cucumber production in Indonesia indicates limitations in conventional cultivation systems, particularly due to land scarcity and inefficient resource management. This condition has encouraged the development of hydroponic systems as a more controlled and productive cultivation alternative. This study aims to critically analyze the key factors determining the success of hydroponic cucumber cultivation and to identify the most influential management aspects in improving yield. The method employed is a literature review, examining various recent studies related to hydroponic systems, nutrient management, growing media, and environmental factors. The results show that the advantages of hydroponics lie not only in land and water efficiency but also in the ability to precisely control growth variables. However, optimal productivity highly depends on the proper integration of nutrient management, particularly the regulation of pH, electrical conductivity (EC), and nutrient balance, as well as the control of environmental factors such as temperature, humidity, and light intensity. Inaccuracy in a single component can significantly reduce plant performance, even when other factors are optimal. Therefore, an integrated approach combining nutrient and environmental management simultaneously is essential to enhance hydroponic cucumber productivity. This study confirms that hydroponics has strong potential as a strategic solution to support sustainable agriculture amid land limitations in Indonesia.

Chili pepper (Capsicum annuum L.) is recognized as one of the horticultural commodities with significant economic value and an important contribution to food security in Indonesia. However, conventional cultivation practices still face various challenges, including limited land availability, climate uncertainty, and disturbances from plant pests and diseases. These conditions highlight the need for the implementation of innovative technologies to improve production efficiency while maintaining yield stability. One approach that has been increasingly developed is the hydroponic system, a cultivation technique that does not rely on soil as a growing medium but instead utilizes nutrient solutions as the primary source of essential elements. This article aims to examine various aspects of hydroponic chili cultivation, including the roles and benefits of the plant, different types of hydroponic systems, abiotic and biotic stress factors, and cultivation management strategies. Based on the review conducted, hydroponic systems, when supported by optimal nutrient management and environmental conditions, are capable of enhancing both the yield and quality of chili plants. Therefore, the development of hydroponic-based chili cultivation is considered to have promising prospects as a solution to support sustainable agriculture in the future.

Soybean is an important food commodity in Indonesia because it is the main raw material for tofu and tempeh, two major protein sources widely consumed by the population. However, domestic soybean production remains far below national demand resulting in heavy dependence on imports. In contrast maize is increasingly preferred by farmers due to its higher productivity and a more stable economic value. Therefore, maize–soybean intercropping has emerged as a promising strategy to improve land-use efficiency while increasing soybean production without reducing maize cultivation. This study systematically mapped and synthesized maize–soybean intercropping research in Indonesia and conducted a meta-analysis of Land Equivalent Ratio LER values reported across studies. Literature searches using Scopus, Web of Science, and Google Scholar identified 179 eligible publications published between 1978 and 2023. Most studies focused on agronomic factors such as variety selection spacing arrangement and fertilizer management. Meta-analysis showed average LER values of 1.47 ± 0.046 for maize–soybean intercropping and 1.36 ± 0.081 for maize–mung bean intercropping indicating advantages over monoculture systems. However, inconsistencies in methodology and reporting standards limited study comparability and sustainability assessments. Future research should integrate ecological, social, and long-term economic indicators alongside standardized reporting frameworks to strengthen evidence-based intercropping recommendations nationally for sustainable agriculture.

The use of synthetic pesticides in the agricultural sector remains the primary choice for farmers in Indonesia due to their high effectiveness, but their massive use has negative impacts on human health and the environment. Therefore, there is a need for environmentally friendly and sustainable pesticide innovations. Red onion peel waste with the addition of TiO₂ nanotechnology is a strategic development step as a solution to the dangers of synthetic pesticides. Red onion peel contains bioactive compounds such as acetogenin, squamocin, gibberellin, cytokinin, and abscisic acid, which have the potential to be natural pest control agents. The process of making organic pesticides is carried out through the maceration of onion skins, followed by the addition of TiO₂ nanoparticles that act as photocatalytic catalysts to increase pesticide effectiveness and degrade synthetic pesticide residues. The development of these organic pesticides is in line with the principles of Green Chemistry, particularly designing safer chemicals, catalysis, design for degradation, and real-time pollution prevention. Through the implementation of strategic steps such as research, testing, socialization, and continuous evaluation, TiO₂ nanotechnology-based organic red onion peel pesticides have the potential to become a safe, effective, and environmentally friendly alternative in supporting sustainable agriculture in Indonesia.

Dependence on chemical fertilizers has caused a decline in soil quality, groundwater contamination, and rising agricultural production costs due to unstable fertilizer prices. In recent years, frequent fertilizer crises have revealed the fragility of reliance on inorganic fertilizers within the national agricultural system. Hence, a transformation toward environmentally friendly and sustainable agriculture is urgently required. This study employed a scoring technique to analyze field observation data, which were narrated based on the written methodology. Respondents’ answers were categorized and classified according to their assumptions or opinions, with scores determined using a Likert scale. The Likert scale measures attitudes, opinions, and perceptions of individuals or groups regarding specific social phenomena. The results showed that key driving factors—such as affordable fertilizer prices, support from agricultural extension workers, and social encouragement from the community—achieved scores above 82%. This finding indicates that external conditions are quite favorable for promoting the use of organic fertilizers. However, major challenges remain, including the limited availability of organic fertilizers in the field and farmers’ long-standing dependency on chemical fertilizers. To address these challenges, it is essential to enhance the market availability of liquid organic fertilizers (POC) through collaboration between producers and farmer groups. Continuous technical assistance should be provided, including demonstration plots that display tangible improvements in rice yields using POC. Furthermore, government support in the form of targeted subsidies or special incentives for farmers transitioning to organic fertilizers is vital, while strengthening the role of farmer groups and agricultural extension workers as catalysts for the adoption of environmentally friendly innovations.

The use of plastic as planting containers remains a serious environmental issue due to its non-biodegradable nature, which can contaminate soil and water. One solution is to utilize rice straw waste as a raw material for biodegradable pots. This innovation can reduce dependence on plastic pots while providing ecological and economic benefits. Rice straw-based pots offer several advantages, including easy decomposition in soil, enhancing soil fertility, and reducing pollution caused by straw burning. This study aims to utilize rice straw waste to produce environmentally friendly biodegradable pots as an alternative to plastic containers. The method employed is Participatory Action Research (PAR), emphasizing collaboration between students and teachers through hands-on learning. The activities include socialization, practical training on making rice straw pots, participatory evaluation, and the use of the pots as planting media. The results showed that 100% of participants successfully produced high-quality rice straw pots, with positive responses reflected in high satisfaction and increased understanding of recycling concepts. The rice straw pots decompose within 2–3 months, add organic matter to the soil, and create opportunities for a circular economy. The main challenge identified is the relatively short durability of the pots, requiring innovations using natural adhesives or material combinations to enhance resilience. These findings reinforce the potential of rice straw as a solution for agricultural waste management and community empowerment toward sustainable agriculture.
