The Effect of Adding Natural Ingredients to Artificial Feed on the Color Brightness Level of Goldfish (Cyprinus carpio Linn). This research aims to determine the effect of adding natural ingredients to artificial feed on the level of color brightness of goldfish (Cyprinus carpio Linn), and the growth rate and survival rate of the test fish. The method used in this research is an experimental method using a Completely Randomized Design (CRD) consisting of 4 treatments and 3 replications with a feeding frequency of three times per day with a percentage of 5% of the body weight of the test fish, a natural ingredient used in making artificial feed. These are pumpkin flour (Cucurbita moschata), mangosteen rind flour (Garcinia mangostana L), and carrot flour (Daucus carota L) with the same dose in each treatment, namely 25% of 1 kg of feed. Based on the results of variance analysis, the brightness level of goldfish color has a very real influence. The highest increase in the color of the test fish was obtained in treatment A, pumpkin flour, amounting to (1.37) on the Toca color finder scale (from pale orange to dark orange), followed by the second highest in treatment C, carrot flour, amounting to (1.2), treatment B flour. Mangosteen peel was in third position with an increase in color of (0.94) and the lowest increase in color change occurred in treatment D (control = without the addition of natural ingredients) of 0.7. However, absolute weight and length growth did not have a real influence. The overall graduation rate is 87.49%. The average water quality parameters are temperature 26-29oC, pH 7.5-7.9 and ammonia 0.25 ppm.

This study aims to obtain data on the suitability of ecotourism areas based on ecological parameters. The parameters observed were mangrove density & thickness, tidal height, mangrove species diversity, and the types of biota that live in it. To calculate mangrove density, the quadratic transect method was used with a size of 10 x 10 m as many as 20 plot pieces. While mangrove thickness is calculated by measuring the outer distance of mangroves towards the mainland. Furthermore, the parameters of biota diversity were carried out by direct observation techniques at the research site. The results of the analysis showed a mangrove thickness of 197.37 metres with a density of 1,520 individuals/ha. There are 10 mangrove species including Sonneratia alba, Avicennia marina, Rhizophora apiculate, R. mucronate, Bruguiera gymnorrhiza, Lumnitzera littorea, Acanthus ilicifolius, Acrostichum speciosum, Pemphis acidula, Nypa fruticans. The average tide height is 1.24 m and 20 species of biota consisting of 3 bivalve species, 1 Gastropoda, 6 fish, 6 birds, 2 shrimps, and 2 crabs.

This research was conducted in February-March 2023, at the Dharmawangsa University Laboratory. The purpose of this study was to determine the effectiveness of fish meal substitution using maggot flour in floating pellets on growth, life expectancy of tilapia and FCR (Food Conversion Ratio). Tilapia is widely cultivated by the community so that it has economic value with high market demand. The high price of feed causes many farmers to suffer losses. To overcome the problem of losses, cultivators use maggot as a substitute for fish meal to be used as a local raw material which has the advantage of being relatively cheap, high protein and increasing the digestibility of fish. The research method used experimental methods with the treatment of artificial feeding with fish meal protein sources and maggot flour protein sources and analyzed using the T test. The results of absolute growth research on fish meal pellets were 3.5 and maggot flour pellets 3.6. This shows that maggot flour can be used as a local raw material in the manufacture of fish feed. The results of the survival rate of tilapia by giving fish meal pellets were 60% and giving maggot flour pellets was 55%. Fish meal pellets and giving maggot flour pellets show that they can support the basic needs of fish and can support fish life. The results of the study showed that the FCR value for fish meal pellets was 1.36 and for maggot flour pellets was 1.36.

Lingkungan V Bagan Deli berada di Kecamatan Medan Belawan. Di Lingkungan ini penduduknya berprofesi sebagai nelayan tradisional dan buruh nelayan Nelayan adalah suatu kelompok masyarakat yang mengandalkan perairan laut sebagai mata pencaharian utamanya, umumnya mereka tinggal di kawasan pesisir pantai dengan sanitasi lingkungan yang kurang baik dan umumnya menggunakan alat tangkap yang sangat sederhana sehingga hasil tangkapannya juga sangat rendah sehingga kebutuhan hidup rumah tangganya sering tidak dapat tercukupi dengan baik. Ketika laut semakin sulit memberi hasil yang maksimal, tak jarang bahkan seringkali hasil tangkapan melaut hanya bisa menutupi kebutuhan satu hari saja. Ketika musim bersahabat saat melaut adakalanya memberikan hasil tangkapan yang melimpah, namun disisi lain harga jual ikannya menjadi turun. Hal ini berdampak pada pemenuhan kebutuhan ekonomi nelayan tradisional dan buruh nelayan tidak tercukupi dengan baik. Tujuan PKM ini adalah memberikan pelatihan teori dan praktek olahan hasil perikanan seperti kaki naga dan fish stick. Sedangkan yang menjadi mitra dalam kegiatan ini adalah Kelompok â€œEmak-Emakâ€ Pesisir Bagan Deli. Adapun metode PKM ini yaitu: 1) share and discussion, 2) theory and try, 3) realisasi.
