This community service aims to provide solutions for fisheries that experience water change problems caused by the lower availability of ground water. The small-medium enterprise (SME) Lele Tamora which is engaged in catfish breeding experiences this problem, such as turbid and bubbly water, which causes mass death of fish seedlings. Therefore, pond fish farming with a modern system integrated by a biofloc system that is supported by the use of microbubbles is introduced to the owner. The basic principle of this system is to utilize bacteria that can release substances that function as adhesives to form biofloc, such as microalgae aggregates, residual pellets, exoskeletons of dead organisms, bacteria, protists, protozoa and others substance with 0.1-2 mm diameter. All of these aggregates can be a source of poison in the pond system or as a competitor for fish to get oxygen. The biofloc system is projected to be able in reducing the toxic content in pond water which automatically reduces fish mortality, and this system can also convert organic waste in ponds into natural food as well as reducing commercial feed. For this purpose, a 1000 liter volume of bioreactor has been constructed to grow biofloc bacterial seeds, 20-liter-capacity of autoclaves to sterilize dissolved oxygen while helping to breed floc-forming aerobic bacteria. This system has been implemented at Lele Tamora SME, and the results showed the changing of water-pond colour from green to brown. Meanwhile, the netting ratio (selection of catfish based on the size of ready-to-sell) increased from 4000 to 8000 individuals.

There are 61 primary/ibtidaiyah schools, 18 junior high schools, and 18 senior high schools in the city of Sibolga, which is located in Teluk Tapian Nauli, with a total number of teachers of about 2000. This is in line with the vision of Sibolga city (2016-2021) in order to create a stable, advanced, and successful Sibolga City by producing highly competitive quality human beings in order to create a harmonious, peaceful, secure and unified society. As mentioned above, one of its mission points is to prepare human resources (HR) that have integrity, reliable, competitive, expert in science and technology so that they able to compete in the global job market. As the education stakeholder, Sibolga Education and Culture Official has plan many outstanding work programs such as made a collaboration in partnership with the Universitas Sumatera Utara community service team. As a result, based on field observations and discussions, it was known that one of the obstacle that facing by the teachers in Sibolga is not being able to provide teaching materials and also picture-based examination questions as contained in the question grid. Currently, there are several technology-driven applications that can be used to make images or graphics creating process easier. Two of them are, GeoGebra Classic that used to create graphics and images in mathematics and Chemdraw that used to create structure images that related to chemistry. In addition word optimization training was also conducted to optimize teacher on preparing teaching materials with Ms. word.

Tamora Catfish Company as a Micro, Small and Medium Enterprise (UMKM) which one of the Universitas Sumatera Utara community service partners, used a simple microbubble technology system to increase the dissolved oxygen content in pond water in order to anticipate of the large number of die fish because of the polluted pond water, which impacted in reducing the amount of oxygen. Biofloc application was observed decreasing the ammonia content and generating natural feed. This was analyze by the team that already implemented this simple technology in the first year observation which found its successfully reduce fish mortality and increase the number of catfish. However, the catfish food is expensive because it is depend on pellet feed, so the production process costs are very high. Via a multi-year system, community service team utilizes conventional market waste as a feed in order to replace the use of costly pellet feed. The solution was starting from processing conventional market waste such as vegetables waste. It was considered because it is cheap and it needs simple machine technology to produce the feed. The machine will construct by copper and mixer in order to produce feed that suitable for catfish food. Furthermore, it also impacted to make conventional market cleaner from waste since partners collect and process the waste directly.

Application of Biopesticide from Eucalyptus grandis on Mortality of Fruit Flies (Bactrocera sp.) on Sweet Citrus (Citrus X Sinensis) Plants Taufik, Muhammad; Zuhra, Cut Fatimah; Cahyady, Boby; Hardiyanti, Rini; Ardilla, Desi; Razali, Mariany; Alfian, Zul

The application of biopesticides is one of the safest alternatives to realize organic agriculture that does not cause harmful impacts to both consumers and the environment. This activity aims to apply biopesticides in eradicating fruit flies (Bactrocera sp.) on Sweet Orange (Citrus X Sinensis) plants. The partner location is the Bukit Rumah Sendi Farmers Group in Karo Regency. Eucalyptus grandis leaves were extracted using steam distillation then the concentration of 1,8 Sineol was determined using GCMS and the concentration was 52%. Eucalyptus oil was mixed with kerosene and detergent then determined the LC50 value in fruit flies and observed for 24, 48, 72, and 96 hours and produced an LC50 value of 35%. This shows that biopesticides are quite effective in eradicating fruit flies.

Fertilizer is the main needed for farmers to support agricultural products. However, the availability of chemical fertilizers in the market was once scarce due to its limited availability. To avoid dependence on the need for chemical fertilizers is to look for other alternatives as plant fertilizers. One alternative to chemical fertilizers is compost produced from organic waste. Compost fertilizer is available in several forms, namely solid fertilizer and liquid fertilizer. In this community service, training was conducted on making a simple composter to make organic fertilizer. The composter produced in this activity is very easy to do and made by partners because it comes from materials that are easily obtained around partners. The advantage of this composter is that it can produce both solid fertilizer and liquid fertilizer at the same time, but the concern of the service team is a liquid fertilizer because its use is more practical and easier for plants to absorb. During the training process, the partners were very enthusiastic about participating in the activity and asking questions related to composting. In this composter, the waste used is organic waste resulting from household waste which is placed at the top of the composter. Then the composter is closed and allowed to ferment by microorganisms. The results of organic liquid fertilizer can be accommodated at the bottom of the composter and then applied to plants in a ratio of 1:10.
