Full text linkDINAMIKA PERIKANAN TEMPIRAI KAWAT (WIRE STAGE TRAP) DI PERAIRAN DESA MANARAP KABUPATEN BANJAR
Full text linkPenelitian ini mengidentifikasi Tempirai Kawat (Wire Stage Trap) di Perairan Desa Manarap Kabupaten Banjar yang meliputi keragaan tempirai kawat, komposisi dan proporsi, sebaran ukuran, dan produktivitas tempirai kawat. Metode yang digunakan adalah Purposive Sampling yaitu turun langsung kelapangan dengan menentukan kriteria-kriteria tertentu yang berkaitan dengan dinamika perikanan tempirai kawat. Analisis data yang digunakan adalah deskriptif. Tempirai yang digunakan di perairan Desa Manarap berbahan kawat, memiliki prinsip seperti perangkap (trap) yaitu mempermudah ikan masuk dan mempersulit ikan untuk keluar. Pengoperasian tempirai dilakukan di daerah rawa atau daerah sawah yang digenangi air dan terdapat vegetasi rawa contohnya seperti purun, kayu duri, eceng gondok dan teratai, dengan hasil tangkapan yang didominasi oleh ikan Sepat rawa (Trichopodus trichopterus), Sepat Siam (Trichogaster pectoralis) dan Nila (Oreochromis niloticus)
This study identified the Wire Stage Trap in the waters of Manarap Village, Banjar Regency, which included the performance of the wire stages, the composition and proportions, size distribution, and the productivity of the wire stages. The method used is Purposive Sampling, which is a direct measurement of the field by determining certain criteria related to the dynamics of the wire tempirai fishery. Data analysis used is descriptive. Tempirai used in the waters of Manarap Village is made of wire, has a principle like a trap, which makes it easier for fish to enter and makes it difficult for fish to get out. Tempirai operations are carried out in swamp areas or paddy fields which are flooded with water and there are swamp vegetation, for example purun, thorn wood, water hyacinth and lotus, with catches dominated by swamp Sepat (Trichopodus trichopterus), Siamese Sepat (Trichogaster pectoralis) and Tilapia (Oreochromis niloticus

Full text linkSTATUS MUTU AIR SUB DAERAH ALIRAN SUNGAI MONTALLAT KABUPATEN BARITO UTARA, PROVINSI KALIMANTAN TENGAH
Full text linkPenelitian ini memiliki tujuan untuk memahami status mutu air Sub DAS Montallat menggunakan nilai indeks pencemaran (IP) serta mengetahui Daya Tampung Beban Pencemar perairan Sub DAS Montallat menggunakan Metode Neraca Massa. Metode pengolahan data yang dipakai penelitian ini adalah indeks pencemaran, daya tamung beban pencemar, dan perhitungan debit. Berdasarkan perhitungan menggunakan metode Indeks Pencemaran (IP), stasiun I tergolong cemarr ringan, stasiun II memenuhi baku mutu dengan kategori cemar ringan, dan stasiun III juga memenuhi baku mutu hingga cemar ringan. Analisis Daya Tampung Beban Pencemar (DTBP) menunjukkan hasil negatif untuk parameter BOD dan DO, sementara parameter TSS, nitrat, dan fosfat menunjukkan hasil positif. Nilai daya tampung menunjukkan bahwa kandungan pencemar pada lokasi tersebut melebihi daya tampung sungai untuk parameter BOD dan DO.
This study aims to determine the water quality status of the Montallat Sub-watershed using the pollution index value (IP) and to determine the Pollutant Load Capacity of the Montallat Sub-watershed using the Mass Balance Method. The data processing method used in this research is pollution index, pollutant load carrying capacity, and discharge calculation. Based on calculations using the Pollution Index (IP) method, station I is classified as lightly polluted, station II meets the quality standard to be lightly polluted, and station III also meets the quality standard to lightly polluted. Analysis of Pollutant Load Carrying Capacity (DTBP) showed negative results for the parameters BOD and DO, while the parameters TSS, nitrate and phosphate showed positive results. The carrying capacity value indicates that the pollutant content at that location exceeds the river's carrying capacity for BOD and DO parameters.
 
IMUNOGENISITAS ANTIGEN HEAT KILLED Aeromonas hydrophila STRAIN LOKAL DESA SUNGAI BATANG DAN MANDIANGIN TERHADAP IKAN LELE DUMBO (Clarias gariepinus)
Full text linkPenelitian ini bertujuan untuk menyeleksi dan mendapatkan antigen bakteri A.hydrophila strain lokal desa Sungai Batang dan Mandiangin Kalimantan Selatan yang bersifat imunogenik terhadap ikan lele dumbo. Antigen diinaktif menggunakan metode pemanasan (heat killed). Rancangan penelitian ini menggunakan Rancangan acak lengkap (RAL) dengan 6 perlakuan 3 ulangan yang meliputi perlakuan vaksinasi dengan antigen Aeromonas hydrophila strain P5.1 (A), strain AM01 (B), strain P1.1 (C), strain P3.1 (D), strain P4.1 (E) dan kontrol diinjeksi dengan PBS pH 7,0 (K). Antigen diinjeksi secara intramuscular sebanyak 0.1 ml (kepadatan bakteri 109 sel/ml) per ekor ikan uji (A,B,C,D,E). Hasil uji imunogenisitas antigen strain lokal P5.1 dan P1.1 bersifat lebih imunogenik terhadap lele dumbo dibandingkan dengan antigen lainnya berdasarkan kemampuannya meningkatkan antibodi pasca vaksinasi. Uji reaksi silang antigen A. hydrophila strain lokal AM01, P1.1 dan P5.1 mampu bereaksi silang dengan antigen lainnya. Antigen P1.1 mampu mengenali antigen lebih banyak dibandingkan P5.1 dan AM01, sehingga dapat direkomendasikan menjadi kandidat vaksin.
This study aims to select and obtain antigens of the local strain A. hydrophila bacteria in Sungai Batang and Mandiangin villages, South Kalimantan, which are immunogenic to African catfish. Antigen is inactivated using the heating method (heat killed). The design of this study used a completely randomized design (CRD) with 6 treatments and 3 replications which included vaccination with the antigen Aeromonas hydrophila strain P5.1 (A), strain AM01 (B), strain P1.1 (C), strain P3.1 ( D), strain P4.1 (E) and control were injected with PBS pH 7.0 (K). Antigen was injected intramuscularly as much as 0.1 ml (bacterial density 109 cells/ml) per test fish (A, B, C, D, E). The results of the antigen immunogenicity test of local strains P5.1 and P1.1 were more immunogenic to African catfish compared to other antigens based on their ability to increase post-vaccination antibodies. Antigen cross-reaction test A. hydrophila local strains AM01, P1.1 and P5.1 are capable of cross-reacting with other antigens. P1.1 antigen is able to recognize more antigens than P5.1 and AM01, so it can be recommended as a vaccine candidate
