Vertiqua biofical top filter is a cultivation technique with a recirculation system that utilizes limited land. Vertiqua is a solution for cultivation. When cultivating koi fish in vertiqua, the feed capacity increases and there is a high nutrient load so that the waters are easily polluted, therefore the presence of an upper biophysical filter can reduce pollution. This is important to study, especially the structure of the phytoplankton community because it is one of the biological indicators of ponds in koi fish cultivation. This research was carried out for 6 weeks in Sindangpalay Ciberem Sukabumi. The research was carried out by taking phytoplankton in the vertiqua at intervals of once every 2 weeks. The data analysis in this research is abundance, diversity, uniformity and dominance. During the research results obtained were abundance 636-673, diversity 2.6, uniformity 0.9, and dominance 0.01. The water quality studied was ammonia, nitrate, nitrite, phosphate, pH, DO, turbidity and temperature. These waters are stable and healthy, which is a positive indicator to support fish farming activities. The water quality in Vertiqua is classified as good and the ecosystem is balanced, these waters are ideal for supporting the productivity and health of farmed fish.

In the era of globalization, the empowerment of local potential has become increasingly important, especially at the village level. The village of Semar in Pagerwojo District, Tulungagung Regency, is a major dairy-producing area, with 60% of its population engaged in dairy farming. However, the Sri Wigati Dairy Cooperative (KUD), which has traditionally been the primary buyer of milk, is facing management issues, forcing farmers to sell their milk to private collectors with limited capacity. As a result, a significant portion of the milk goes unsold, posing a potential economic loss. To address this, a previous community service initiative taught farmers how to process milk into milk crackers, although these products have remained limited to local consumption despite their added value. Therefore, the focus must shift to the regional or national market. This community service program aims to: 1) enhance the competitiveness of local products, 2) empower the community, 3) optimize the value chain, 4) increase income, 5) develop a sustainable business model, 6) foster partnerships, and 7) improve community knowledge and skills.

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.

The author's motivation for undertaking this study stems from a previous observation that instructors continued to employ an expository method that was monotonous and devoid of variety. The instructor primarily employs the lecture method to impart the learning material, which restricts their ability to utilise infrastructure and facilities such as mind mapping and concentration for the students. This form of inquiry employs descriptive qualitative research methodology, specifically characterising a symptom associated with a current event. By utilising data collection methods such as documentation, interviews, and observation. Class V students served as the primary informants, while the Islamic Religious Education Instructor and the School Principal provided supplementary information. Following this, the author conducts data analysis through data reduction, data presentation, and conclusion drawing from the study. The findings of the study indicate that: 1) The expository method was implemented with PAI subjects. After conducting research on its learning applications, it has been optimised. Because educators possess a professional demeanour and impart knowledge in accordance with their academic credentials. 2) Possessing assets that serve as corroborating elements in the instructor's implementation and utilisation of learning resources pertaining to Islamic religious education that are accessible and deemed satisfactory in their efficacy. However, there are impediments: a) the teacher's capacity to design learning is constrained (insufficient), b) the length of the teacher's explanations is excessive, c) the reliance on textbooks lacks creativity and is monotonous, and d) educators' endeavours to surmount challenges are also hindered. when the expository method is applied to PAI subjects:. 3) Efforts made by educators to overcome inhibiting factors in the application of expository methods, especially in PAI subjects, can be overcome by developing expository methods, such as using teaching aids, and supplementing with worksheets, and using textbooks that are less imaginative, rigid, and emphasized. on factual learning, memorization, and so on. Thus, it can be stated that the application of the expository method in the implementation of the Islamic Religious Education learning process produces a good learning process and can improve student learning achievement.
