Abstract

Ikan teri (Stolephorus sp) merupakan sumberdaya alam yang melimpah di Indonesia. Seperti halnya produk ikanasin lainnya, mikroba merupakan faktor utama penyebab kerusakan dan menjadi permasalahan yang harusditanggulangi. Sebagian besar produsen ikan teri kering tidak memperhatikan cara penjemuran yang higienis.Oleh karena itu dibuat TLD yang mempunyai spesifikasi dimensi 4 m x 7,5 m, menggunakan dua sistem bloweryaitu turbin ventilator dan exhaust fan. Hasil pengeringan menggunakan TLD kadar air ikan teri 33,47%,kapasitas pengering 60kg. Selisih hasil pengeringan sebesar 40kg/hari, jika dalam satu bulan (20 hari kerja),maka selisihnya 800kg/bulan. Untuk harga netto ikan teri kering Rp 10.000,00/kg, maka dalam satu bulan terjadipeningkatan pendapatan sebesar Rp 8.000.000,00. Selain terdapat peningkatan pendapatan sebesar 100%,penggunaan TLD lebih higienis.

Abstract

Green mussel (Perna viridis) is oyster has high potential to be developed. A huge market demand is an important factor to optimized green mussel cultivation, there are to system that could be applied for cultivation green mussel is polyculture and monoculture. The purposed of this study is to determined growth performance of green mussel which culture in monoculture and polyculture system. Green mussel is culture in floating cage bath of monoculture and polyculture system. In polyculture system green mussel placed within seabass (Lates calcarifer). Growth performance of green mussel determined by comparizing growth in wide and body lenght using T-test to analyzed factor that assigned to growth performance used principle component analysis (PCA) to environment factor such as Total Amonia Nitrogen (TAN), Total Organic Matters (TOM), Total Suspended Solid (TSS) and phytoplankton both in polycultured and monocultured system. The result of this research was shown that growth in this significant shown from third place where sample collected at 0-100 in depth The results showed that this significant growth was shown from the third place where the samples were collected at 0-100 in depth and the second place where the samples were collected at 100-150 in depth. This is caused by availability of feed source such as TOM and phytoplankton thy driven by sea current. The significant value shown by growth in wide of mussel shell at 100-150 cm in depth.

Abstract

Tuba (Derris elliptica) root was used traditionally as a poison to fish catching. This research looks for beneficial of tuba root extract as an anesthetic for the transport of fish seed. This research aims was to explore the value of effective concentration (EC50 - 1 hr) of tuba root extracts by ethanol and hexane, as well as determine the effect of the effective concentration value and the period of transportation time on the survival and growth of common carp seed. Probit analysis used to determine the effective concentration , whereas to determine the effect of differences of periods of transportation (2 , 4 and 6 hours) and the value of the effective concentration of each solvent on the survival and growth of the research design uses factorial analisis. The results of probit analysis for ethanol and hexane solvent are 6.166 and 3.72 ppm. Transportation showed the highest survival rate at treatment of transportation period 2 hour with values ​​reaching an average of 100%, while the highest growth occurres in hexane treatment on the period of transportation of 6 hours. This results also found that the period of transportation differences significantly affect the survival of common carp seeds but has no significant effect on the growth of common carp other results showed that the difference in the solvent not significantly affect the survival and growth of common carp seed.

Abstract

Water quality plays an important role in aquaponics system. Water chemistry parameter that may affect water quality is total organic carbon. Sources of carbon in the aquaponics system mainly derived from the decomposition of organic matter which derived from artificial feed and plant respiration. The research was conducted to study the reduction of total organic carbon concentration in the aquaponic system and the relation of abundance and diversity of phytoplankton. This research using different amount of ipomoea (Ipomoea aquatica) consist of 10, 20, and 30 rods and control treatments which use without ipomoea. The results showed that all of ipomoea treatments can reduce the amount of total organic carbon concentration in the aquaponics system. This research showed that nutrients cycle in the aquaponics system, especially total organic carbon dissolved in water is influenced by many factors such as plants, fish and primary productivity which determined by the plankton. Furthermore, a positive correlation occurred between total organic carbon concentration of the abundance and diversity of phytoplanktons (r = 0.5925; r = 0.6364). These results can be used for preliminary study of nutrient cycle model in aquaponic system.

Abstract

Pasaran Island waters is the location of green mussel cultivation (Perna viridis), where the waters has the potential to experience heavy metal pollution including Cadmium (Cd). Green mussels are filter feeders and have a slow movement, thus they have the potential to experience heavy metal bioconcentration on their bodies. The aim of this study was to determine the bioconcentration of heavy metal cadmium (Cd) in green mussels (Perna viridis) which were cultivated in the waters of Pasaran Island. Samples were collected in February 2018 in green mussel cultivating cages of Pasaran Island water with 3 and 6 cm mussel size. Sampling was taken at three stations with three replications each. The Cd content was analyzed using AAS method. The results showed that the water content of Cd at the observation location ranged from 0.022 to 0.024 mg/l. The content of Cd of mussel meat is 0.030 to 0.033 mg/kg, the value is below the threshold based on Indonesian National Standard (SNI). The BFC value of 3 cm mussel is 1.33 mg/kg, while the 6 cm mussel is 1.47 mg/kg which indicates that the green mussels on Pasaran Island are accumulatively low on Cd.

Abstract

Peningkatan sisa pakan dan buangan metabolit yang terakumulasi dapat menyebabkan peningkatan fosfat sehingga kualitas air menjadi rendah yaitu menurunnya kadar oksigen terlarut pada perairan. Salah satu cara untuk mengatasi masalah tersebut yaitu mengaplikasikan sistem resirkulasi dengan penambahan filter. Penelitian ini bertujuan untuk mengetahui penurunan fosfat pada sistem resirkulasi dengan penambahan filter yang berbeda. Penelitian ini dilaksanakan pada bulan Juli sampai dengan bulan September 2013 di Jurusan Budidaya Perairan Fakultas Pertanian Universitas Lampung. Hewan uji yang digunakan sebagai penghasil fosfat yaitu lele sangkuriang (Clarias gariepnus) berukuran 3-5 cm/ekor dengan padat tebar 200 ekor/m2 dan dipelihara selama 60 hari. Desain penelitian menggunakan rancangan acak lengkap dengan empat perlakuan yaitu kolam tanpa filter (kontrol), kolam dengan filter zeolit, kolam dengan filter arang dan kolam dengan filter pecahan karang dimana setiap perlakuan diberikan tiga kali ulangan. Hasil penelitian menunjukkan bahwa penggunaan filter yang berbeda menyebabkan terjadinya penurunan fosfat yang berbeda nyata (P>0,05). Penurunan fosfat tertinggi terjadi pada jenis media filter arang yaitu sebanyak 0,02675 mg/l, sedangkan penurunan fosfat terendah terjadi pada jenis media filter zeolit yaitu sebanyak 0,021 mg/l
