Limited land resources are a problem for fisheries, especially in urban areas. So the need for a new innovation in the field of fisheries for cultivation. Vertiqua (Vertical Aquaculture) is an innovation in vertical cultivation in limited land and water. The Vertiqua system as a cultivation medium has not been effective in increasing fish growth due to slow growth and high ammonia levels. Therefore, innovation is needed to increase the effectiveness of Vertiqua, namely by using the upper biofical filter. The data used to analyze is descriptive analysis by describing and describing the data that has been collected. Growth in length, weight, and survival, length-weight relationship, daily length growth rate, daily weight growth rate, and water quality were calculated using existing formulas. Comparative testing of growth was calculated using the T-test on the Mini Tab application. The results of the research showed that the top filter biofical vertiqua was able to increase the growth of koi fish. The growth value of the top biofical filter vertiqua is effective when compared to the soil pond. this is indicated by the value P<0.05. The upper biofical filter vertiqua system is also able to maintain the stability of water quality and suppress ammonia levels so that fish growth and survival are good. The vertiqua system with the upper biofical filter has an effect on fish growth, this is supported by the upper biofical filter, which is able to maintain water quality and suppress ammonia levels so that fish are not stressed and feed can be utilized properly.

The growth of comet fish (Carassius auratus) in the vertiqua system using a biofical filter is motivated by limited land and water which can cause low water quality to affect the growth rate of fish. The utilization of technology needs to be done to overcome these problems and the technology used is vertiqua. Previous research showed that comet fish in the vertiqua system produced slow growth rates and had high ammonia levels. Therefore, vertiqua was modified in the filter section to become a biofical filter. The purpose of this research is to test the effectiveness of comet fish growth in the vertiqua system using a biofical filter. The benefits of this research are that the vertiqua system using a biofical filter can be a solution to overcome the problem of limited land and water, become a support for system cultivation innovation, and become a reference for further research. This research method uses descriptive methods, observation and interviews. The comet fish used in the study were 3-4 cm in size. The results of this study indicate that the vertiqua system using a biofical filter is still not effective in supporting fish growth. The growth rate of comet fish in the vertiqua system is significantly different from that in the soil pond and the growth rate of comet fish in the vertiqua system is lower than that of comet fish in the soil pond. Ammonia value is relatively high from the quality standard (>0.05). However, this system is able to maintain good fish survival and good water quality, especially in temperature, pH, and DO.

Heavy metals are chemical elements that can be toxic even at low concentrations. The presence of non-essential heavy metals in the environment can contaminate soil, water, and air. The consequences of this contamination affect the living organisms in the surrounding area. For instance, heavy metals in soil and water can contaminate plants growing in the region, which may then be processed as daily food sources, potentially impacting the health of those who consume them. Heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), and arsenic (As) are non-essential heavy metals that are of primary concern due to their toxic nature. The presence of heavy metals in food can hinder the growth and development of children, making it crucial to implement educational initiatives and preventive measures to reduce heavy metal contamination in daily consumed foods. This activity involves educating people about the dangers of heavy metal contamination in food and the actions that can be taken to reduce the concentration of heavy metals in the food we consume.

Field Study and Community Service is a community service program which is a form of implementation of the Tri Dharma of Higher Education. One area that is often focused on in KKN is agriculture. Agriculture in Indonesia still faces various problems, one of which is farmers' dependence on the use of chemicals as fertilizers and pesticides. The use of chemicals in agriculture can have long-term negative impacts such as damage to soil structure. One approach that can be applied is the use of animal waste as a natural ingredient in making organic fertilizer. Through Field Study and Community Service program, outreach and training is provided to the community regarding techniques for using animal waste as organic fertilizer. This activity was carried out using methods starting from surveys, outreach, and practice of processing goat manure waste into organic fertilizer. Socialization accompanied by direct practice can provide farmers with more knowledge to understand and apply techniques for making organic fertilizer more effectively. In addition, the use of organic fertilizer can reduce farmers' dependence on chemical fertilizers, increase soil fertility, and optimize agricultural yields.

Soil stabilization is a common technique to improve the mechanical properties of the soil in term of increasing its strength and decreasing the associated settlement. The new sustainable materials have been emerged as alternative to the traditional binders such as the cement and the lime. These materials can be used in the shallow and deep soil mixing. This paper reviewed the mechanism of the soil stabilization, the traditional binder and the sever impacts on the environment, the new echo-friendly materials, deep soil mixing technique, and the geopolemerization. The results showed significant enhancement of the shear strength of the geopolymerized silt where the strength was increased by more than 6 times. This enhancement may be attributed to the developed geopolymer-jel NASH that filled the voids, surrounded and cemented the soil particles. Consequently, this matrix considered as a novel precursor for using in the soil injecting and grouting technique. 

The Kediri Airport development project encountered challenges related to underground ducting work. The design of Kediri Airport adheres to international standards, which led to the use of materials not readily available in Indonesia, specifically pipes and duct spacers. Duct spacers are tools used to arrange ducting pipes according to their formation and prevent them from floating during concrete pouring due to buoyancy. The SKEP/114/VI/2002 serves as a reference for underground cable installation, involving direct burial of cables at a depth of 70 cm, covered with a 5 cm layer of sand above the cable surface. These two approaches significantly differ, necessitating problem-solving solutions. To address this issue, research was conducted to find suitable duct spacers in Indonesia. Two alternative materials were considered: PVC and lightweight hollow steel. The study compared costs and time associated with these materials. PVC duct spacers would be imported and be fabricated in Indonesia, while hollow steel duct spacers would be fabricated on-site. The research focused on three aspects: ducting work methods, duct spacer design, and cost-time analysis. Given tight installation spaces and busy schedules, duct spacers needed to be compact, simple, and adaptable to various pipe formations. The design for hollow steel duct spacers aimed for simplicity to reduce on-site construction work. However, care was taken to avoid potential injuries from exposed bolts on the hollow steel frame. The PVC duct spacer design utilized Polytam PF 1000 material, with a nominal shear strength of 399 kg and a nominal moment of 266 kg·cm—sufficient to withstand saturated soil loads up to 162 cm but not vehicular loads. Analyzing procurement time, PVC duct spacers from Indonesian manufacturers were the quickest, taking only 56 days due to no port clearance delays. The fastest completion time for the project was achieved using PVC duct spacers, taking 122 seconds—three times faster than hollow steel duct spacers. While lightweight steel was the most cost-effective option for on-site procurement, combining cost and time analysis favored PVC duct spacers. The minimal cost difference allowed for accelerated production, minimizing the risk of delays
