The negative impacts of the climate change phenomenon have a very broad impact, including on the agricultural sector, thus threatening food resilience in Indonesia. This research aims to find out how the regulation of climate change adaptation in the agricultural sector achieves food resilience in Indonesia, and to find out how its implementation occurs specifically in the regency of Kubu Raya, West Kalimantan Province, and Bandung City, West Java Province. Using a normative legal and analytical-descriptive approach, the main data are primary legal data and legal literature. The results showed that there are several climate change adaptation provisions in the agricultural sector in Indonesia, but food diversification as an adaptation measure is not contained in them. This makes the implementation of the agreements in Kubu Raya constituency try to adapt only to a commodity. Nevertheless, the implementation of climate change adaptation in the agricultural sector, especially in Kubu Raya constituency and Bandung city, has been pursued despite the respective problems outside the threat of climate change.

Crop productivity is one of the key components in supporting the sustainability of the agricultural sector and global food security. However, challenges such as soil degradation, dependence on chemical fertilizers, and climate change necessitate more innovative and environmentally friendly approaches. Soil microorganisms play a significant role in improving crop productivity through biological mechanisms such as nitrogen fixation, organic matter decomposition, mycorrhizal symbiosis, and the production of bioactive compounds that protect plants from pathogens and abiotic stress. Microbiology-based biotechnology approaches, such as the use of biofertilizers and biopesticides, offer environmentally friendly solutions to address modern agricultural problems. This research aims to review the role of microorganisms in improving crop productivity, focusing on the application of microbiology-based biotechnology. The research method used is a literature study or meta-analysis of relevant literature and research in the last 10 years. The results of the discussion show that microorganisms such as Rhizobium, Azospirillum, Trichoderma, and mycorrhiza have a major contribution in improving soil fertility, crop yields, and plant resistance to environmental stress.

Soil fertility is an important element in agricultural sustainability, especially in supporting plant growth. One natural way to increase soil fertility is through Biological Nitrogen Fixation (FNB) by Rhizobium bacteria. These bacteria have a symbiotic relationship with legume plants, forming root nodules that convert atmospheric nitrogen into compounds that plants can absorb, such as ammonium (NH4+). The purpose of this article study is to determine the potential of Rhizobium bacteria in increasing and efficiency of nitrogen fixation which has an impact on soil fertility and increasing plant productivity. This study adopts a library research method or approach, which involves a series of systematic activities, starting from collecting data through various library sources, reading in depth, recording important information, to processing the research materials. The study results show that Rhizobium can reduce dependence on chemical fertilizers, increase soil fertility, and produce growth hormones that support nutrient absorption. These findings emphasize the important role of Rhizobium in supporting sustainable agriculture, especially in tropical regions where access to synthetic fertilizers is minimal.

The use of nitrogen-fixing bacteria in agriculture is an effective way to improve soil fertility and overall crop productivity. Bacteria such as Rhizobium, Azotobacter, and Azospirillum are able to extract nitrogen from the soil and convert it into a form that can be absorbed by plants, which is essential for the formation of protein, DNA, and RNA in plants. By utilizing the capabilities of these bacteria, the use of synthetic chemical fertilizers can be varied, thereby reducing the detrimental dampening effects on water quality and the environment. In addition, nitrogen-fixing bacteria improve water use efficiency and contribute to the health of aquatic ecosystems. The use of these bacteria has the potential to improve the results of a more thorough analysis with less cost and less environmental impact.

Soil fertility is a key element in the sustainability of agricultural systems that support global food security. One important soil microorganism that plays a role in improving soil fertility is Rhizobium, a bacterium capable of biological nitrogen fixation through a symbiotic relationship with leguminosae plants. This bacterium not only contributes to increasing soil nitrogen availability by 30-50% but also helps reduce dependence on synthetic nitrogen fertilizers, which has implications for reducing greenhouse gas emissions. Nonetheless, the effectiveness of Rhizobium is strongly influenced by environmental conditions such as pH, salinity, and chemical pollutants, which can inhibit its symbiotic ability. Technological innovations, such as nano-based formulations and the development of superior strains, offer solutions to improve the efficiency of Rhizobium, but challenges such as high costs and lack of policy support remain. In addition, the widespread use of Rhizobium inoculants may disrupt the balance of the soil microbial ecosystem, requiring further research. Therefore, integration of technology, policy and farmer education is needed to optimally utilize the full potential of Rhizobium while mitigating environmental risks, to support a more sustainable agricultural system.

This study aims to determine the composition and structure of vegetation and estimate the potential for carbon dioxide absorption in the Tangale Nature Reserve Area, Gorontalo Regency. The method used in this study is the determination of sampling locations carried out by purposive sampling, making multilevel plots, analyzing vegetation structure, and estimating tree biomass is done non-destructively based on measuring the height and diameter of trees at breast height (DBH), while for lower plants it is done destructively and litter is taken all in the plot area to be weighed wet and dry weight and then estimating biomass, C reserves, and CO2 uptake. The results showed that the vegetation composition consisted of 18 species dominated by the Magnoliopsida class. The highest Important Value Index is found at each observation station. Calculation of biomass value, C reserves, and CO2 uptake at each observation station showed varying results because they were influenced by vegetation type, vegetation density, vegetation composition and structure, and environmental factors. The total value of CO2 uptake by vegetation in the Tangale Nature Reserve Area is 5,304.393 tons of CO2/ha. This research provides a better understanding of carbon sequestration potential in conservation areas to support environmental conservation and climate change mitigation efforts.
 

The current reliance on chemical fertilizers has caused many problems in agricultural practices, such as the decline in soil quality and crop resistance to environmental stress. Farmers are encouraged to use chemical fertilizers, due to the lack of efficiency of nutrient absorption in plants which results in a lack of productivity of agricultural products. This research aims to review in depth the role of Mycorrhizal fungi in increasing the efficiency of nutrient uptake by plants. The research method used is the literature review method to explore more deeply the role of mycorrhizal fungi in increasing the efficiency of plant nutrient uptake. The results stated that mycorrhizal fungi have great potential as microorganism partners in increasing plant nutrient uptake. With its ability to expand the root absorption area, and enhance plant growth, improve soil structure and reduce pollution, mycorrhiza can contribute significantly to agricultural sustainability.

Soil microorganisms have an important role in improving soil health and supporting sustainable organic agriculture. They contribute to the decomposition of organic matter, management of nutrient cycles, control of pathogens, and improvement of soil structure. This research explores the role of microorganisms, such as bacteria, mycorrhizal fungi, and actinobacteria, in supporting soil fertility by increasing the availability of nitrogen, phosphorus, and potassium for plants, as well as improving soil quality by increasing water retention capacity and reducing erosion. These microorganisms also act as biocontrol agents that inhibit pathogens, thereby reducing the need for chemical pesticides. However, managing soil microorganisms faces major challenges due to environmentally unfriendly agricultural practices, such as the use of pesticides and chemical fertilizers. This research emphasizes the importance of implementing sustainable agricultural principles to conserve soil microorganisms and maintain the health of the soil ecosystem as a whole. This study aims to provide insight into the role of soil microorganisms in increasing organic agricultural yields and recommend more effective and environmentally friendly management. These findings are expected to support the development of more productive and sustainable organic agriculture.
 

Soil pollution is a global problem with anthropological and natural sources. Pesticides are chemical compounds used to eradicate pests. Pesticides are chemical or biological agents that can weaken, paralyze, and kill pests. According to a report by FAO (2021), global pesticide use reaches more than 4 million tons per year, with Asia accounting for nearly 50% of total consumption. In Indonesia, data from the Ministry of Agriculture (2022) shows that pesticide use increased by 15% in the last decade. Unfortunately, the intensive and uncontrolled use of pesticides has triggered the accumulation of harmful residues in the soil, creating a serious threat to soil, environmental, and human health. The purpose of this study was to determine how the utilization of microbiology in the bioremediation of agricultural soil polluted with pesticides. The method in this journal article uses a library study (library research), namely a method with data collection by understanding and studying theories from various literatures related to the research. The results show that soil bioremediation to reduce pesticides in agricultural soils can be done by utilizing specific or local microorganisms (bacteria and fungi), or enzymatic degradation. Although in laboratory scale, many findings on soil bioremediation are available in the literature, only few data on real scale activities can be found.
 
 

This research aims to explore the role of soil microorganisms in improving soil fertility and agricultural productivity to support sustainable agriculture. Using the literature review method, various scientific literatures were analyzed to identify the potential, challenges, and optimization strategies of microorganism technology. Microorganisms such as Nitrobacter, Streptomyces sp. and Trichoderma sp. play significant roles in nitrogen cycling, organic matter decomposition and plant pathogen control. In addition to naturally improving soil nutrition, these microorganisms also support agricultural efficiency by reducing dependence on synthetic chemical fertilizers and pesticides.  However, the adoption of this technology faces obstacles, such as farmers' lack of knowledge and limited access to quality products. Therefore, strategic steps are needed in the form of training programs, extension, and policy development to support the implementation of microorganism-based technologies. In the context of climate change, microorganisms also contribute to greenhouse gas mitigation and increase crop tolerance to abiotic stress. The results of this study emphasize the importance of microorganisms as a sustainable solution to the challenges of modern agriculture, as well as the need for collaboration between various parties to increase the capacity of farmers in implementing this technology.
