Koi fish culture is influenced by good water quality as a life medium. The problem in koi fish farming is the decline of water quality caused by pollution and the results of koi fish metabolism. The experiment methods are koi fish rearing tanks preparation, making a series of recirculation aquaculture system (RAS), stocking koi fish seeds, and measuring water quality. The RAS technology range consists of a pipe, a pump, and a filter tank consisting of an arrangement of charcoal, bioball, zeolite, and sand. For one month the maintenance of koi fish using RAS technology gave good results on the growth and quality of the cultured water. Koi fish seeds before rearing measuring 5-6 cm experienced an increase in the body length to 8.5-10.5 cm. The results of measurements of temperature, pH, and DO of koi fish culture water before recirculation include 31.2°C; 7.6; and 4.8 mg/L, respectively. After the recirculation process, the results of temperature, pH, and DO measurements were found to be 29.7°C; 7.1; and 6.0 mg/L, respectively. This shows that RAS technology can to optimize the temperature, pH, and DO of koi fish cultured water. Optimal water quality will lead to good koi fish growth.</p> 2022-07-20T16:09:33+07:00 Copyright (c) 2022 Jurnal Teknologi Perikanan dan Kelautan https://journal.ipb.ac.id/index.php/jtpk/article/view/41765 AKUMULASI LOGAM BERAT TIMBAL (Pb) PADA HATI IKAN PATIN (Pangasius djambal) DI WADUK SAGULING, JAWA BARAT 2022-08-02T12:37:49+07:00 Ai Nuraeni onosulistiono@gmail.com Agustinus Samosir agus.samosir@gmail.com Sulistiono Sulistiono onosulistiono@gmail.com <p>Saguling Reservoir is one of the reservoirs built in the Citarum Watershed which is quite polluted, and has a potential to contain heavy metals (such as Pb). The Pb will be concentrated in the body of catfish (<em>Pangasius djambal</em>) which is commonly cultured in the reservoir and in the long term will accumulate. Liver is an organ that accumulates the most heavy metals so that it has the potential to cause damage in the form of necrosis, fibrosis, and cirrhosis. This study aims to analyze the content of Pb that accumulates in the liver and its effect on liver tissue damage. This study was conducted in December 2012 through sampling carried out at three stations representing the inlet, middle, and outlet. Analysis of Pb content (in the water and fish) was conducted using AAS (Atomic Absorption Spectrophotometer) and obtained Pb heavy metal content (in fish) ranging from 7.5 to 16.4 mg/kg. The Pb content in the catfish had exceeded the quality standard based on SNI 2009 (for fish and its processed products). Liver tissue damage caused by Pb accumulation in the Saguling Reservoir was swelling and necrosis.</p> 2022-07-25T14:48:35+07:00 Copyright (c) 2022 Jurnal Teknologi Perikanan dan Kelautan https://journal.ipb.ac.id/index.php/jtpk/article/view/40468 PENGARUH PERBEDAAN JENIS UMPAN TERHADAP HASIL TANGKAPAN SIDAT (Anguilla sp) DI SUNGAI SIKUCING, KABUPATEN PURWOREJO 2022-08-02T12:37:45+07:00 Wazir Mawardi wazir@apps.ipb.ac.id Anggraini Cahyaningtias wmawardi@gmail.com Julia Eka Astarini jujea@apps.ipb.ac.id Fis Purwangka fis@psp-ipb.org <p>One of the economically valuable fish in the Sikucing River is an eel. Sikucing River is an upstream river located in Purworejo Regency, Central Java. The eel in Sikucing River is usually captured using a handline with diverse baits. The research aims to determine the type of bait favored by the eel. The baits used in this research were worms, shrimp, golden snails, and coconut caterpillars. The research uses four types of bait because the availability of these baits is still a lot and affordable. The research was conducted for 36 days and in one day there were two bait installments (namely the afternoon and evening). Bait installments were carried out at eight locations along the Sikucing River. Based on the research there are five types of fish caught on handline, namely eels, carps, snakehead fishs, lempon fishs, and turtles. The dominant catch from this research was eel with 40 individuals (or 30,173 kg). The eels were caught on all four types of bait, but the highest catch was obtained from the type of coconut caterpillar bait. Shrimp and snail were a type of bait that has the lowest eel catch (as many as 3 individuals).</p> 2022-07-27T16:06:39+07:00 Copyright (c) 2022 Jurnal Teknologi Perikanan dan Kelautan https://journal.ipb.ac.id/index.php/jtpk/article/view/40487 FORMULASI FOOT SPRAY ANTI BAU KAKI BERBASIS NANO CHITOSAN DARI LIMBAH INDUSTRI UDANG 2022-08-02T12:37:41+07:00 Anita Ervina anitaervina42@gmail.com Fahri Sinulingga sinulingga98fahri@apps.ipb.ac.id Mohammad Rofiqi moh.rofiqi97@gmail.com Tiara Fitri Erinanda tiaraerinanda1998@gmail.com Kustiariyah Tarman Kustiaz@apps.ipb.ac.id Andi Baso Manguntungi sinulingga98fahri@apps.ipb.ac.id La Ode Fitradiansyah sinulingga98fahri@apps.ipb.ac.id <p>One of the solutions to the problem of anti-odorous feet is the use of anti-odor products. One of the natural ingredients that have the potential as an anti-odor agent is chitosan. Chitosan in the form of nanoparticles is more reactive and has higher antibacterial activity. Until now, shrimp industrial waste has not been explored much, so that the utilization of shrimp industrial waste into nano chitosan can increase the added value of shrimp waste. This study aims to find the most effective foot spray formulation in inhibiting bacteria that cause foot odor. The stages of this research were the manufacture of chitosan, nano chitosan, foot spray formulation, physical properties test, antibacterial activity test, physical stability test, and irritation test. The manufacture of nanochitosan was done using the ionic gelation method. Chitosan was dissolved with distilled water, 0.1% TPP, and Tween 80 and disizing at a speed of 23,000 rpm to form stable nanoparticles. The nano chitosan concentration of 3,000 ppm gave the highest inhibitory power of 5.20 mm against <em>S. epidermidis</em> and 3.15 against <em>Micrococcus</em> sp. The degree of acidity, particle size, and sensory value of foot spray nano chitosan was stable during 8 weeks of storage, but the viscosity decreased significantly.</p> 2022-07-29T15:59:48+07:00 Copyright (c) 2022 Jurnal Teknologi Perikanan dan Kelautan https://journal.ipb.ac.id/index.php/jtpk/article/view/41314 VARIABILITAS SUHU PERMUKAAN LAUT DAN KONSENTRASI KLOROFIL-A DI SAMUDERA HINDIA BAGIAN TIMUR LAUT SEBELAH BARAT SUMATERA 2022-08-08T08:32:03+07:00 Bisman Nababan bisman@apps.ipb.ac.id Evelyn Grace Br Sihombing simson_naban@yahoo.com James P. Panjaitan simson_naban@yahoo.com <p>The variability of sea surface temperature (SST) and concentration of chlorophyll-a (Chl-a) in the Northeastern Indian Ocean west off Sumatra was studied using satellite data over a period of 22 years. The study used a combination of NOAA-AVHRR and MODIS data for SST, SeaWiFS and MODIS data for Chl-a, and monthly surface wind data from the European Center for Medium Range Weather Forecasts (ECMWF). Supporting data such as the monthly El Nino Southern Oscillation (ENSO) index and the Dipole Mode Index (DMI) were obtained from the web page of https://www.ncdc.noaa.gov/teleconnections/ enso/indicators/soi/ and https://www. jamstec.go.jp/virtualearth/general/en/index.html, respectively. The results showed that the range of SST during 22 years (1997-2019) was 27,57°C-34,41°C where the higher SST occurred during the West Season and Transition Season-1, while the lower values were found during the East Season and Transition Season-2. The negative IOD caused higher SST and lower Chl-a concentration than normal. Chl-a for 22 years ranged from 0,0757 mg/m<sup>3</sup>-1,3006 mg/m<sup>3</sup> where higher Chl-a occurred start from the end of East Season (August) to early West Season (December), while lower values were found during Transition Season 1. The evidence of higher SST around Transition Season 1 (March-May) coincided with the evidence of lower Chl-a in the same seasons was due to negative IOD phenomenon. The variability of SST and Chl-a was influenced by the patterns of the seasonal wind, the water mass circulation, and IODM.</p> 2022-08-02T11:05:22+07:00 Copyright (c) 2022 Jurnal Teknologi Perikanan dan Kelautan
