Previously, germination was reported in many studies that could improve the nutritional status and bioactive compounds in brown rice. However, the change of those functional properties was randomly different in diverse varieties. This study aimed to evaluate the change in chemical composition and functional properties of germinated brown rice from the Mentikwangi variety, one of the local paddy rice in Indonesia. Brown rice was germinated using the soaked and aeration method for 48 h. After that, the proximate compositions were analyzed including the change of total phenolic compounds and radical scavenging activity. We observed that germination in Mentikwangi brown rice significantly increased the crude protein content, but reduced the lipid and total carbohydrate contents. Moreover, the antioxidant activity was improved in germinated Mentikwangi brown rice sample due to the improvement of total phenolic compounds. These results affirm the previous studies which concluded that germination attenuated the functional properties of brown rice, so that has the potential to be developed as a future functional food.

Indonesia is a country with a high level of earthquake vulnerability, thus demanding innovation in building structural engineering that is not only safe but also environmentally friendly. In the context of sustainable development, bamboo as an abundant local material is starting to gain attention as an alternative to conventional materials. Bamboo, when processed into composites in the form of fibers or in combination with thermoplastic and thermoset polymers, has been proven to have superior mechanical properties, including tensile strength, stiffness, and resistance to chemical degradation. In addition, the characteristics of water absorption that are controlled through certain treatments make bamboo composites more competitive compared to synthetic materials. The application of bamboo composites in construction is not only limited to new materials in structural elements, but also effective in retrofitting methods. For example, recent research shows the potential of bamboo composites in strengthening reinforced concrete beams and improving the performance of frame systems in earthquake-resistant structures. In line with this, seismic design regulations and standards such as the comparison between SNI 1726:2012 and SNI 1726:2019 demonstrate the importance of adapting structural designs to local seismic conditions. The integration of bamboo composite materials with structural capacity analysis, numerical simulation, and pushover analysis methods has yielded promising results for improving building resilience to dynamic loads. Beyond technical aspects, this approach also supports environmental objectives. Several studies have even developed eco-friendly home prototypes utilizing innovative material combinations, including geopolymer blocks and natural fibers. Thus, the use of bamboo composites not only provides a technical solution to earthquake challenges but also contributes to global efforts to reduce the carbon footprint of the construction sector.

This journal looks at the legal concerns of managing natural resources by producing compost using a market-based method based on garbage. This study's primary goal is to evaluate the efficacy and compliance of the legal requirements controlling the use of market trash as a raw material for compost fertilizer. The study's findings indicate that there are several pertinent laws that offer a legal framework for market waste management, including the Environmental Law and government waste management rules. However, there are obstacles to the law's implementation and enforcement, such as a lack of knowledge among business actors and oversight flaws. To ensure sustainability and efficiency in managing market waste as a resource for making compost, this study also found that, despite the existence of existing regulations, regulatory updates and harmonization are still required. To maximize the environmental and economic benefits of market waste management, this research recommends improvements in regulations and law enforcement, as well as increased education and training for business actors.The results of the study indicate that the utilization of market waste for making compost has great potential in supporting organic farming and reducing the volume of waste that ends up in landfills. However, the implementation of this program requires a deep understanding of applicable regulations, as well as support from the government and the community. This article concludes that comprehensive legal-based waste management can improve the efficiency and sustainability of natural resource management, as well as have a positive impact on community welfare.

Body composition refers to the distribution of fat, muscle, bone, and other tissues in the human body, which is often expressed as a percentage of total body weight consisting of fat mass and lean body mass. Obesity, characterized by excess fat in adipose tissue, poses a significant health risk and is increasing in countries with low and medium mortality rates, especially in metropolitan areas. Factors contributing to this include genetics, a lack of physical activity, socioeconomic status, unhealthy eating patterns, psychosocial factors, smoking, and alcohol consumption. Excess body fat significantly contributes to morbidity and mortality. Although optimal body fat levels vary, excess fat increases the risk of health issues such as joint problems and cardiovascular disease. People widely use bioimpedance analysis (BIA), an efficient, non-invasive method, to assess nutritional status and body composition. This activity uses the PDCA (Plan-Do-Check-Action) method, which is carried out at PT. Narindo, North Jakarta, in the productive age population. The examination results showed that the average levels of total body fat, visceral fat, total subcutaneous fat, total muscle mass were 28.6%; 11%; 22.2%; 28.3%. Early detection of body composition is critical for assessing nutritional and health status as well as diagnosing disease, potentially reducing obesity-related morbidity and mortality.

In Indonesia, the use of inorganic fertilizers is one area that is produced continuously to be used to increase crop yields, especially vegetables. Organic fertilizer and compost also have long-term benefits because they can increase the fertility of plants such as coffee. Indonesia is a coffee producer with unique characteristics. There is one type of coffee that is not widely known by the Indonesian people, namely Excelsa coffee. Excelsa coffee has very distinctive characteristics and aroma. Most of Wonomerto's residents have agricultural land and livestock that can produce coffee and livestock. However, villages that have cattle farms are still unable to utilize animal waste properly, and also residents who have coffee production only process it into ground coffee. Therefore, educational events and new programs for the Bokashi compost coffee market are being held. Apart from that, agricultural products and animal products that cannot yet be processed can be used as organic fertilizer using EM4 technology. The benefits of bokashi fertilizer are that it can increase the nutrient content of plants, reduce organic waste, and encourage the growth of plant microorganisms.
