Abstract

Artikel ini berisikan peranan modal sosial dalam operasional UMKM sektor ikan hias. Tulisan ini dilakukan dengan studi kepustakaan. Tulisan ini menitikberatkan pentingnya penerapan modal sosial dalam operasional UMKM sektor ikan hias. Pembahasan dilakukan dengan elaborasi antara konsep Modal sosial dalam operasional UMKM. Modal sosial yang berunsur kepercayaan, norma, dan jaringan sosial menjadi kunci dalam operasional UMKM di sektor ikan hias. Penerapan ketiga unsur modal sosial ini tidak dapat terpisah. Masing-masing membentuk keterkaitan yang rumit dan menjadi dasar keberlanjutan usaha di sektor ikan hias. Kesimpulan dalam artikel ini adalah modal sosial dalam operasional UMKM di sektor ikan hias menjadi penting untuk diterapkan karena pengembangan usaha bergantung pada konsistensi dari penerapan semua unsur modal sosial hingga dapat berkelanjutan.

Abstract

Aquaculture activities generally use commercial feed to fullfill the nutritional needs of fish. The use of commercial feed can increase production costs, because they still use imported raw materials. To reduce production costs, can use alternative feed by utilizing local materials. Palm oil is one of the abundant local raw materials in Indonesia and produce underutilized waste such as loose palm oil. This study aims to determine the effect of using loose palm oil as an alternative feed on catfish. This study consisted of three treatments (control, soft loose palm oil, and wormy loose palm oil) of three repeats each. Feeding catfish with ad satiation for 28 days. Parameters observed include survival rate, absolute weight growth, absolute length growth, and spesific growth rate. The results showed that the best treatment was the use of wormy loose palm oil feed with a survival rate of 100%, absolute weight growth of 44,23 g, absolute length growth of 6,20 cm, and spesific growth rate of 10,22%.

Abstract

Red dragon fruit peels (Hylocereus polyrhizus) are an organic waste that has not been widely used with nutrients such as fibre, carotene, calcium phosphorus, vitamin B and vitamin C as antibacterial and antioxidant. This research was conducted to analyze the addition of red dragon fruit peel flour as a prebiotic for tilapia (Oreochromis niloticus). Fingerling of tilapia with an average size of 17.76 ± 1.35 g were reared for 30 days in an aquarium with a volume of 30 L. The fish were fed three times a day at satiation with treated feed, namely P0 0%; P1 5%; P2 10%; and P3 15% dragon peel flour kg-1 of feed. Each treatment was repeated three times. Parameters observed included the number of lactic acid bacteria in the gut of fish, growth performance, survival rate and haematological parameters. The results showed that the highest number of lactic acid bacteria at P3 was 5.38 log CFU mL-1, the absolute weight growth was 12.60 g, and the specific growth rate was 1.87% day-1. Supplementation of red dragon fruit peel flour did not affect the survival rate of tilapia, which ranged from 73.33- 80.00% and the haematological parameters showed a normal range. Based on this, red dragon fruit peel flour has the potential as a prebiotic in tilapia up to a dose of 15% kg-1 of feed.Keywords: Dragon Fruit Peels Flour; Growth Performance; Hematological Parameters; Prebiotics; Tilapia
