Abstract

Kegiatan budidaya ikan lele tidak terlepas dari berbagai permasalahan salah satunya penyakit. Keberhasilan budidaya ikan lele dipengaruhi oleh beberapa faktor, salah satunya adalah pengendalian serangan penyakit bakteri. Ikan lele rentan terhadap penyakit yang disebabkan oleh infeksi bakteri Aeromonas hydrophila. Bakteri A. hydrophila dapat menyebabkan Motile Aeromonas Septicemia (MAS). Pengendalian penyakit pada ikan lele (Clarias Gariepinus) sering menggunakan antibiotik jenis enrofloxacin. Penggunaan antibiotik dapat menimbulkan dampak negatif salah satunya dapat menimbulkan resistensi.Penelitian ini bertujuan untuk menganalisis jenis bakteri pada ikan lele di Kabupaten Pasuruan dan respon bakteri tersebut terhadap antibiotik enrofloxacin serta memperoleh gambaran histopatologi hati, ginjal dan limpa. Penelitian ini merupakan penelitian deskriptif dan eksperimental dengan menggunakan Rancangan Acak Lengkap (RAL). Sampel terdiri dari 25 sampel ikan lele yang diambil dari 5 kecamatan di Kabupaten Pasuruan. Kecamatan Beji 10 sampel, Kecamatan Rembang 6 sampel, Kecamatan Purwosari 3 sampel, Kecamatan Gempol 3 sampel dan Kabupaten Bangil 3 sampel. Inhibisi bakteri menggunakan 3 perlakuan enrofloxacin yaitu perlakuan A (5 µl), B (7,5 µl) dan C (10 µl). Analisis data menggunakan SPSS seri 25 dengan uji ANOVA dan dilanjutkan dengan uji jarak berganda Duncan.Hasil penelitian menunjukkan bahwa Aeromonas hydrophila teridentifikasi pada 23 sampel dan Aeromonas salmonicida pada 2 sampel. Tidak terdapat resistensi bakteri Aeromonas hydrophila terhadap antibiotik jenis enrofloxacin yang ditunjukkan dengan rata-rata zona hambat terendah pada perlakuan A dosis 5 µl di Kecamatan Purwosari dan rata-rata zona hambat tertinggi diperoleh pada perlakuan C dosis 10 µl di Kecamatan Purwosari. Terjadi kerusakan pada ginjal, hati dan limpa ikan yang diberi Aeromonas hydrophila. Kerusakan pada ginjal meliputi degenerasi, pusat makrofag melano, infiltrasi sel inflamasi, dilatasi pembuluh darah dan kongesti dan nekrosis. Kerusakan pada hati termasuk degenerasi, sinusoid melebar dan kongesti dan nekrosis. Kerusakan limpa termasuk makrofag, perdarahan dan nekrosis. Kesimpulan dari penelitian ini adalah dosis optimal enrofloxacin untuk ikan lele (Clarias gariepinus) di Kabupaten Pasuruan adalah 5 µl.

Abstract

The use of fishery waste emphasizes a cyclical system in the production process, thereby creating clean production. Shrimp waste can pollute the environment around the factory so it needs to be utilized. One of the processing methods that can be done using shrimp heads is to make flavour. Islamic boarding schools and economic independence in an effort to develop Islamic boarding schools - are two things that cannot be separated. Training on fishery waste processing is one method to support economic independence in the form of entrepreneurship in Islamic boarding schools. Processing fishery product waste is an activity carried out in stages, sequentially, cleanly and hygienically, and meets quality requirements in order to convert fishery product waste into value-added products. The target of this community service activity is to establish a solid fishery waste processing business activity at the Nurul Huda Islamic Boarding School in Surabaya and be able to compete in the market continuously. The method used is an approach method that includes, among others, the Participatory method. The results that have been obtained from this activity are an increase in the knowledge of Islamic boarding school students about fishery waste, namely shrimp heads which are used as a flavouring/flavoring ingredient for safe cooking. The activity was attended by 43 students, with educational levels namely middle school and high school. Based on questionnaire data distributed, before the training was carried out, it was found that 93% of the students did not know that shrimp head waste could be used as a flavour. After the training, it was found that 94% of students were interested in making their own flavor production made from shrimp heads.

Abstract

Abstract In the ornamental fish business, transportation has an important role to distributing fish up into the costumers. The distance between the farm and the customers location, require a transportation method which can maintain the quality and quantity of ornamental fish during the transportation. The biggest challenge in live fish closed system transportation is to reduce the stress level of fish during the process. According to Harmon (2009), fish are often exposed to multiple stressor during the transportation. Stressed fish can be seen through the increasing of tachiventilation (rapid opercula movement) and blood glucose levels (Evans and Claiborne, 2006). One of the method to reduce stress of fish during transportation is using essential oils from Bandotan's (A. conyzoides) leaves. A. conyzoides essential oils know has an analgesic activity (Okunade, 2002; Shekhar and Anju, 2012; Singh et al., 2013). A chemical compound with known analgesic effect, used in human and veterinary medicine as local analgesic dan be used to fish for the purpose of sedation, immobilization, and analgesia as well as general anaesthesia (Zahl and Samuelsen, 2012). This research was conducted to see the effect of A.conyzoides essential oils toward the survival rate, blood glucose levels, and tachyventilation of koi carp juveniles during closed system transportation. This research using completely randomized design method which consist of 5 different treatments with 4 replications. Treatment that used in this research is the variation of administration doses of A. conyzoides essential oils during the koi carp juvenile closed system transportation. The treatment such as A (5 ppm), B (10 ppm), C (15 ppm), D (20 ppm), and E (0 ppm). Main parameter of this research is survival rate, blood glucose levels, and tachyventilation of koi carp juvenile during 8 hours transportation. The result shows that A. conyzoides essential oils give a significant result toward survival rate, blood glucose levels, and tachiventilation of koi carp juvenile during transportation. There is no mortality in treatment A, B, and E, during transportation. The lowest blood glucose levels and tachiventilation found in treatment A (5 ppm).
