Abstract

Udang vannamei merupakan salah satu komoditas perikanan yang bernilai ekonomis penting. Tingginya permintaan terhadap udang vannamei menyebabkan pentingnya kegiatan budidaya. Namun adanya berbagai permasalahan pada budidaya udang vannamei menyebabkan diperlukannya suatu teknologi untuk meningkatkan produksi. Tujuan kegiatan ini adalah untuk mengaplikasikan penyediaan probiotik, aplikasi immunostimulan, dan pengukuran kualitas air di tambak yang ada di Desa Pangkah Wetan dan Pangkahkulon, Kecamatan Ujung Pangkah, Kabupaten Gresik sebagai upaya untuk peningkatan produksi hasil panen tambak udang vannamei. Kegiatan ini dilaksanakan pada bulan Juli-Agustus 2019. Metode kegiatan ini adalah penyuluhan, peragaan, diskusi, dan demoplot di lapangan. Hasil kegiatan ini adalah anggota kelompok mitra berpartisipasi aktif dalam setiap tahapan kegiatan yang dilakukan. Materi yang diberikan bertujuan untuk meningkatkan pertumbuhan dan melindungi udang dari penyakit, menjaga kualitas air, dan menekan kematian udang untuk peningkatan produksi. Hasil pengukuran kualitas air dilapangan menunjukkan bahwa kondisi suhu di tambak kelompok mitra yaitu 320C, kecerahan 50 cm, warna air kecoklatan, dan pH 7.

Abstract

Chitosan is a functional polysaccharide that is capable of inducing various biological activities. This research aims to examine the effect of chitosan on growth and blood profile of tilapia fish. The method used in this research was experimental methods with completely randomized design (RAL) consisting of 4 treatments and 3 times. 120 Tilapia fish in 5-7 cm in range size were reared in aquarium at density of 10 fish/aquarium. Feedwere given at the additional dose of 10 ppt, 50 ppt, and 100 ppt chitosan. The observed variables were growth rate, survival rate, fish blood profile, water quality, feed utilization efficien . The results showed that the best chitosan treatment was at a dose of 100 ppt which produced FCR of 3.48 ± 2.25, AGP: 0.13 ± 0.03, SGR: 0.85 ± 0.84 and EPP: 28.70 ± 16,54.

Abstract

Tilapia is a consumable fish that is needed in large quantities so that cultivation is carried out with dense stocking. The disadvantage of dense stocking is that the cultivation waste from feces or residual feed is quite high so it is necessary to apply a technology, namely aquaponics. This technology is the basis for community service in a limited location at the Deles Merr Culinary Tourism Center, Surabaya. The aim is to provide knowledge about aquaponics which is a combined system of fish and vegetable farming. Fish feces and feed residue are useful as fertilizer for vegetables so that water quality becomes optimal. The community service was conducted through counseling and mentoring methods on the application of aquaponic technology for tilapia (O. niloticus) and lettuce (L. sativa) cultivation on limited land. The target to be achieved is to increase knowledge, empowerment and improve skills in producing fish and vegetable farming businesses. Assistance in the form of an observation study of the application of aquaponic technology for tilapia (O. niloticus) and lettuce (L. sativa) cultivation on limited land resulted in growth rate (GR) data of 1.2 gr/day and specific growth rate (SGR) of 0.05%/day. Lettuce plants absorb ammonia produced from feces and remaining tilapia feed, thus optimizing water quality which has an impact on growth rate and specific growth rate. The community has gained knowledge and applied aquaponic technology in tilapia (O. niloticus) and lettuce (L. sativa) farming.

Abstract

HighlightsLitopenaeus vannamei has been established as alternative to Penaeus monodon to shrimp farming in several countries.Increased importance of in situ microorganisms both in regulating biogeochemical cycles within the culture environment and in directly affecting shrimp growth and survival.To improve water quality in aquaculture is the application of probiotics and/or enzymes to ponds. AbstractIntensive shrimp farming has raised environmental issues due to aquaculture pollution, which is caused by uneaten feed, feces, organic matter, and toxic compounds (ammonia and H2S). One way to solve this issue is by using probiotics. Thus, this study aimed at investigating the effect of probiotic administration (Pseudomonas sp. and Bacillus sp.) at varying concentrations on total organic matter in the rearing water, feed conversion ratio, feed efficiency, and growth rate of white shrimp (Litopenaeus vannamei). This study used a Completely Randomized Design consisting of four treatments: T0 (without the probiotic supplementations), T1 (probiotics at 106 CFU/ml), T2 (probiotics at 107 CFU/mL), T3 (probiotics at 108 CFU/mL) with three replicates each. The results showed that the administration of probiotics at different concentrations had a significant effect on the total amount of organic matter, feed conversion ratio, feed efficiency, and specific growth rate of white shrimp. Administration of probiotics at a concentration of 107 CFU/ ml had the lowest organic matter in the rearing water, 138 mg /Lt. While probiotic administration at 108 CFU/ ml gave the lowest feed conversion ratio (1.22), the highest feed efficiency (81.57%) and the best growth rate (2.25%/day). This research suggests that the administration of 107-108 CFU/ ml probiotics could be applied to reduce organic content in the rearing water and improve the growth performances of white shrimp.

Abstract

Aeromonas hydrophila adalah penyakit bakteri pathogen yang berperan penting dalam menyebabkan kematian pada komoditas ikan nila. Pada penelitian ini, pakan yang mengandung asap cair tempurung kelapa yang dapat diaplikasikan sebagai imunostimulan untuk mengobati penyakit Motile Aeromonad Sepricemia (MAS) pada ikan Nila. Penelitian ini bertujuan untuk mengetahui pengaruh asap cair tempurung kelapa pada uji aktivitas antibakteri secara In vitro dan uji tantang A. hydrophyla secara uji In vivo. Tahapan uji invitro meliputi uji MIC, uji sensitivitas asap cair, dan antibiotik ampicillin sebagai kontrol. Selanjutnya pada uji invivo dengan mencampurkan setiap 100gr pakan yang mengandung asap cair dengan dosis 1%, 3%, 5%, 7% dan 9% (v/w). Selanjutnya uji tantang tantang dilakukan dengan menyuntikan suspensi bakteri A. hydrophila dengan dosis 106 sel/cfu sebanyak 0,1 ml secara oral pada pakan dan variabel pengamatan meliputi total eritrosit, hemoglobin, kadar hematokrit dan gejala klinis ikan nila. Analisis data menggunakan Anova dan diuji DMRT dengan selang kepercayaan 95%. Hasil penelitian menunjukan bahwa konsentrasi asap cair terbaik secara invitro dengan MIC 1% dan sensitivitas asap cair 9% dengan diameter 5.63 cm, sedangkan uji tantang yang paling efektif pada perlakuan 3% dapat menurunkan infeksi A. hydrophyla pada ikan nila dengan jumlah total eritrosit (106/L): 2,27±0,15, total hemoglobin (g/dL): 8,03±0,21, dan kadar hematokrit (%): 21,35±1.34 (p < 0.05). Ikan nila yang diuji tantang dengan A. hydrophila pada perlakuan kontrol menunjukkan gejala sirip geripis, sisik mengelupas, hemoragic, dan exopthalmia. Sedangkan perlakuan yang diberikan asap cair melalui pakan menunjukan kondisi ikan nila lebih baik pada gejala klinis dan analisis hematologi daripada ikan yang tidak diberikan perlakuan.
