Abstract

The fish bone waste treatment program for the application of useful products, specifically as a natural ingredient of the drinking water filter.This program works with coastal communities in terms of providing raw materials. This program is a social innovation from the transfer of knowledge of the university's inventors to the coastal communities, in the aim to maintain and improve the cleanliness of the environment, which is then applied for the purpose of developing a water filter system. The contribution of this organic product is useful for Small, Micro & Medium Enterprises engaged in the production of food and beverages, as well as donations for cosmetic and health products to industries, as well as donations to policy development, through the application of environmental physics and science development to product development, pre-commercialization and commercialization (social engineering & manufacturing). The involvement of coastal communities in utilizing their waste is to achieve the empowerment of coastal communities, emphasizing community involvement to learn and cooperate for future development goals. Prior to the formation of this program, the community who failed to take care of its waste often had the waste dumped into the sea, rivers and garbage collection sites. The disposal causes the form of pollution problems that invite various dangerous diseases and cause the community environment to be clean, smelly and diseased. The results of the research have been done, Fish bone waste can be processed to be a product of water filter system resulting from fish processing industry, which contains high calcium. Fish bones are very rich in calcium that is needed by the human body, because the main elements of fish bones are calcium and phosphorus. The use of fish bone calcium is widespread such as overcoming coastal pollution and other environments in the disposal of heavy metals such as Zinc (Zn), Copper (Cu), Lead (Pb), and Iron (Fe).

Abstract

This research utilized baking filter dust (BFD) waste obtained from PT. INALUM., which functions as a heat retainer, is processed into briquettes with the addition of coconut shell charcoal, which has not been fully utilized. This research is also to determine the optimum quality of physical and chemical properties in good briquettes to be used as an alternative fuel. This study uses the method used is the pyrolysis method with the combustion process using a closed combustion furnace and sieving using a sieve with a size of 50-100 mesh. The quality of briquettes was analyzed using the Proximate Test, Ultimate Test, and Characterization of SEM – EDX. Furthermore, the quality test of briquettes refers to SNI 016235 2000 and the Minister of Energy and Mineral Resources No. 47 of 2006; the average moisture content of briquettes is 18.65 %, the average ash content of briquettes is 4.33 %, the average volatile matter content (volatile matters) is 13.30 %, the average fixed carbon content (fixed carbon) is 63.73 %, the average heating value is 6,200 cal/g, and the sulfur content is 49.75 % on average.

Abstract

Yttrium-substituted M-type barium hexaferrite was successfully synthesized using the solid-state reaction method. X-ray diffraction (XRD) confirms that all various samples have a single phase (for x = 0,0 and 0,1), have increased trend for crystal size (from 56,99 to 59,34 nm), cell volume (from 697,9161 to 701,2375 Å), and lattice parameter (a = 5,8948 to 5.9024 and c = 23,1918 to 23,2422) caused by ion substitution increased. SEM-EDX figure shows that the particle shape of yttrium-doped barium hexaferrite is hexagonal, and there is a growth in particle size as the amount of doping increases from 1.050 to 1.202 µm, and also the amount of Y3+ ion doping increases, the number of Fe atoms decreases, and the number of Y atoms increases. The materials were characterized using a Vector Network Analyzer (VNA), which shows a minimum reflection loss of x = 0.1 reaching -7,34 dB in the X-band for a thickness of 1.5 mm, better sample variation when compared to other sample variations.

Abstract

This research was motivated by the large potential of dry leaf waste in the campus environment of the University of North Sumatra and the awareness of the importance of appropriate innovation in the use of dry leaf waste as an environmentally friendly alternative fuel. The aim of this research was to determine the potential of leaf waste in the campus environment as a raw material for making environmentally friendly charcoal briquettes. The research method was observation, conducted in the campus environment of the University of North Sumatra, followed by calculating the amount of leaf waste produced per day, and testing continued with the production of dry leaf briquettes. The test results of the three combustions with different mixtures of raw materials in each combustion resulted in solid dry leaf briquettes that could ignite well. This study produced briquettes with proximate and ultimate tests that met SNI No.01-6235-2000 standards with a moisture content test of 4.35%, ash content test of 5.65%, carbon content test of 78.68%, calorific value of 6115 cal/g, and a burning rate of 1.5 grams/minute. Briquettes that meet SNI standards can become an environmentally friendly alternative energy source, a source of livelihood, and will certainly have a positive impact on waste management on the campus of the University of North Sumatra.
