Abstract

Tujuan penelitian ini untuk mengetahui pertumbuhan dan kelangsungan hidup ikan hias Platydoras (Platidoras costatus) yang dipelihara dengan menggunakan teknologi bioflok. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 2 perlakuan dan 5 ulangan.  Perlakuan dalam penelitian ini adalah: Perlakuan A (Tanpa Bioflok), B (Dengan Bioflok). Ikan uji yang digunakan adalah ikan hias Platydoras yang memiliki panjang 1,9–2,1 cm. Ikan dipelihara selama 40 hari dan diberi pakan 2 kali sehari. Parameter yang diamati meliputi laju pertumbuhan harian, kelangsungan hidup, pengukuran kualitas air dan kepadatan bakteri. Hasil penelitian menunjukan bahwa penambahan bioflok memberikan pengaruh yang berbeda nyata (P<0,05) terhadap laju pertumbuhan harian, dan tingkat kelangsungan hidup (SR). Kepadatan bakteri di awal penelitian (9.6x104 CFU/ml), pada akhir penelitian memiliki nilai rata-rata pada perlakuan tanpa bioflok berkisar 7.84x105 CFU/ml sedangkan nilai rata-rata pada perlakuan bioflok berkisar 4,3 x106 CFU/ml, Hasil indentifikasi pada awal penelitian terdapat 4 jenis bakteri yaitu Streptobacillus sp, Enterobacter sp, Kurthia sp, Aeromonas sp. pada akhir penelitian terdapat 2 jenis bakteri pada perlakuan tanpa bioflok (Streptobacillus sp dan Aeromonas sp) dan 2 jenis bakteri pada perlakuan bioflok (Streptobacillus sp dan Kurthia sp.). Kata Kunci: bioflok, pertumbuhan, platydoras, jenis bakteri.GROWTH AND GOING FISH LIFE PLATYDORAS (Platydoras costatus) FISH IN BIOFLOK TECHNOLOGYABSTRACT The purpose of this research is to know the growth and survival of Platydoras ornamental fish (Platidoras costatus) which is maintained by using biofloc technology. This study used Completely Randomized Design with 2 treatments and 5 replications. The treatments in this study were: Treatment A (Without Biofluok), B (With Bioflok). The test fish used are Platydoras ornamental fish that has a length of 1.9-2.1 cm. Fish kept for 40 days and fed 2 times a day. The parameters observed included daily growth rate, survival, water quality measurement and bacterial density. The results showed that the addition of bioflock gave significant different effect (P <0,05) to daily growth rate, and survival rate (SR). The density of the bacteria at the start of the study (9.6x104 CFU / ml), at the end of the study had an average value of treatment without biofloc ranging from 7.84x105 CFU / ml while the mean value of biofloc treatment ranged from 4.3 x106 CFU / ml, at the beginning of the study there were 4 types of bacteria: Streptobacillus sp, Enterobacter sp, Kurthia sp, Aeromonas sp. at the end of the study there were 2 types of bacteria on treatment without biofloc (Streptobacillus sp and Aeromonas sp) and 2 types of bacteria on biofloc treatment (Streptobacillus sp and Kurthia sp.).

Abstract

ABSTRACT  Koi fish is one of the species included in the intensification program of ornamental fish production. Production of koi has only reached 82.04% of total national production target thus making it potential for development. The objective of the study was to assess additional financial benefit of production increment through stocking pattern modification. Present research was performed using case study method on Pokdakan PBC Fish Farm (PPFF), koi fish farmers in Sukabumi. Financial analysis consisted of business analysis, investment criteria, and sensitivity. Stocking pattern management could increase ornamental fish production and its benefit margin up to 1.5 times higher. That investment criteria has shown NPV at value of IDR3,824 million, net BCR 4.96, IRR 86.0%, and PP 1.7 years. Koi fish farming was sensitive to a decline in survival rate and insensitive to the rise of formulated feed price. Keywords: business analysis, koi, investment criteria, production pattern, sensitivity  ABSTRAK  Ikan koi merupakan salah satu ikan yang termasuk dalam program penguatan produksi ikan hias Indonesia. Capaian dari target produksi ikan koi yang ditetapkan pemerintah hanya mencapai 82,04 %, sehingga budidaya ikan koi potensial untuk dikembangkan dan ditingkatkan produksinya. Metode yang digunakan adalah studi kasus pada kelompok pembudidaya ikan hias koi PPFF di Sukabumi. Analisis finansial yang digunakan meliputi analisis usaha, kriteria investasi dan sensitivitas. Pengaturan pola tebar dapat meningkatkan jumlah produksi ikan hias dan marjin keuntungan hingga 1,5 kali. Analisis kriteria investasi menghasilkan nilai NPV sebesar Rp3.824 juta, net B/C 4,94, IRR 86,0% dan PP 1,7 tahun. Budidaya ikan koi sensitif terhadap penurunan kelangsungan hidup dan tidak sensitif terhadap peningkatan harga pakan buatan. Kata kunci: analisis usaha, koi, kriteria investasi, pola tebar, produksi
