Rapid urbanization has led to an increased demand for food in urban areas. At the same time, land limitations and dependence on external supplies pose significant challenges to food security. Urban agriculture is an innovative solution for producing local food using limited land and modern agricultural techniques such as hydroponics, aquaponics, vertical farming, and rooftop gardens. This approach allows urban agriculture to be more resource-efficient, reduces distribution costs, and minimizes its environmental impact by lowering its carbon footprint. In addition to environmental benefits, urban agriculture also brings social and economic benefits by raising awareness of food sustainability, creating new business opportunities, and enhancing food independence in urban communities. This research uses a literature review method to examine various articles discussing the development, obstacles, and implementation of urban agriculture in different countries. The results show that urban agriculture makes an important contribution to improving food security while also providing a sustainable alternative for the global food system. Therefore, promoting the growth of urban agriculture from the perspective of sustainable food security requires support from government institutions, the private sector, and local communities.

This study aims to explore the root growth patterns of cucumber (Cucumis sativus L.) cultivated in a polybag system, and examine the implications for nutrient absorption efficiency and plant survival. The method used was a systematic literature review, with narrative analysis of recent studies in the last five years. Data were analyzed to identify the relationship between root architecture, growing medium, and nutrient absorption efficiency.  The results showed that the polybag system, with its limited root growing space, promoted adaptation of root growth patterns, including an increase in lateral root density and a reduction in primary root length. Coconut fiber- and vermiculite-based growing media were shown to increase nutrient absorption capacity by up to 30%, while inoculation of rhizosphere microorganisms, such as mycorrhiza, increased phosphorus use efficiency by up to 25%. In addition, optimal root zone temperature plays an important role in supporting root metabolic activities.  The conclusion of this study confirms that optimizing root growth patterns through growing media, temperature management, and utilization of microorganisms can significantly increase the productivity of cucumber plants. These findings provide a basis for developing more efficient and sustainable cultivation strategies in modern horticultural systems. 

Organic farming is increasingly being looked at as a solution to improve soil quality and produce sustainable agriculture. This study aims to explore the impact of organic farming on soil quality and yields of wet-rice farming in Nias Islands. Based on existing research, organic farming systems are proven to provide great benefits to soil fertility, including by increasing organic matter content, boosting soil microbial activity, and improving soil structure. The use of techniques such as crop rotation, organic fertilizers and mulching have been shown to improve soil quality, increase its ability to store water and reduce erosion. In addition, more diverse and active soil microbes also contribute to more efficient nutrient cycling, reducing dependence on synthetic fertilizers and helping to control pests naturally. While the initial adoption of organic farming may result in lower yields, research shows that in the long run, yields increase as soil quality improves. Organic farming also offers better resilience to climate change, especially in terms of the soil's ability to retain water and reduce the impact of drought. Thus, organic farming in Nias Islands can not only increase agricultural productivity, but also support environmental sustainability. Therefore, the application of organic farming is the right choice to improve food security and preserve nature in Nias Islands

Using organic fertilizer can increase soil fertility, which is crucial for plant growth. Another organic material source that may be utilized as fertilizer is water hyacinth (Eichhornia crassipes). The chemical makeup of water hyacinth was examined in this study, and the results indicated that its organic matter content was 78.47%, its organic carbon content was 21.23%, its total nitrogen content was 0.28%, its total phosphorus content was 0.0011%, and its total potassium content was 0.016%. It has been demonstrated that applying water hyacinth-based liquid organic fertilizer to corn (Zea mays) plants actually affects crop output. Utilizing water hyacinth not only improves soil fertility but also lessens pollutants in the environment caused by overgrowth in waterways. Water hyacinth can therefore be utilized as a sustainable and eco-friendly organic fertilizer option.

This study examines the main pests and diseases that attack cayenne pepper (Capsicum frutescens) plants grown in polybags. In Indonesia, this crop is in high demand for both household and industrial use. Nonetheless, farmers often face challenges from pest and disease attacks, including anthracnose, fusarium wilt and stem rot, leading to reduced yields. The methodology used was a literature review covering various sources related to cayenne pepper. Findings show that important diseases such as anthracnose can reduce yields by up to 80%, while pests such as fruit flies can cause chili fruits to drop prematurely before harvest. Effective pest and disease management is essential to increase the productivity of cayenne pepper cultivated in polybags.

Cyanobacteria play an important role in the evolution of the earth and biosphere. Cyanobacteria play a role in the oxygenation of the atmosphere and oceans that began since the great oxidation event. These living things are the main producers in the ocean in the past and present and are the ancestors of Chloroplasts. The morphology commonly used is still difficult to read for microfossil interpretation which makes the identification of cyanobacteria in the early fossil record still ambiguous. This study was conducted to review classical and new cyanobacterial biosignatures. In addition, this study will also analyze the fossil record of cyanobacteria mentioned earlier and the challenges of molecular approaches to modern cyanobacteria. The suggestions we provide are new calibration points for molecular clocks and strategies to increase insight into the timing and patterns of cyanobacteria evolution and oxygenic photosynthesis.

This article aims to observe the effect of hypertonic sucrose solution concentration on plasmolysis of epidermal cells of Rhoeo discolor leaves. Plasmolysis occurs when plant cells lose air due to the surrounding hypertonic solution, which causes the cytoplasm to shrink and the plasma membrane to detach from the cell wall. In this experiment, Rhoeo discolor leaves were immersed in sucrose solutions with different concentrations (0.14 M to 0.26 M) for 30 minutes, and the percentage of plasmolyzed cells was calculated. The results showed that the higher the sucrose concentration, the more cells underwent plasmolysis. At low concentrations (0.14 M and 0.16 M), plasmolysis occurred at a small percentage (1.77% to 7.25%), while at high concentrations (0.24 M to 0.26 M), the percentage of plasmolyzed cells increased significantly, reaching 3.03% at a concentration of 0.26 M at the 30th minute. In addition, prolonging the immersion time to 30 minutes caused a decrease in the number of plasmolyzed cells, indicating that osmotic equilibrium was reached after a certain time. Overall, this study confirms that hypertonic environmental concentration has a direct effect on plant cell plasmolysis, with the intensity increasing with higher environmental concentrations.
