Abstract

ABSTRAKPermasalahan dalam budidaya ikan lele adalah penyakit yang disebabkan oleh infeksi parasit. Tujuan penelitian adalah untuk mengidentifikasi jenis ektoparasit dan mengkategorikan tingkat prevalensi, intensitas dan dominasi ektoparasit pada benih ikan lele sangkuriang. Penelitian ini dilaksanakan bulan Juli 2022. Metode yang digunakan yaitu pengambilan sampel benih ikan lele sebanyak 80 ekor secara acak, pemeriksaan ektoparasit dan pengukuran kualitas air. Proses identifikasi ektoparasit dilakukan di laboratorium Balai Karantina Ikan Pengendalian dan Mutu kelas 1 Sentani. Hasil identifikasi ektoparasit diperoleh tiga jenis parasit yaitu Dactylogyrus sp., Gyrodactylus sp., dan Trichodina sp.. Ektoparasit tersebut menyerang organ yang berbeda yaitu lendir, insang dan sirip. Parasit yang paling banyak ditemukan adalah dari ordo monogenea yaitu jenis Dactylogyrus sp. dengan tingkat prevalensi 60% dalam kategori Frequently (sangat sering). Sedangkan ektoparasit dengan prevalensi terendah yaitu Gyrodactylus sp. dan Trichodina sp. dengan tingkat prevalensi 30%. Kesimpulan dari penelitian adalah nilai rataan prevalensi Dagtylogyrus sp. sebesar 48,75%, Gyrodagtylus sp. sebesar 21,25% dan Tricodina sp. sebesar 21,25 %. Selanjutnya nilai rataan intensitas Dagtylogyrus sp. adalah 2,50 %, Gyrodagtylus sp. adalah 1,55 % dan Tricodina sp. adalah 1,64 %. Kemudian nilai rataan dominansi Dagtylogyrus sp. sebesar 64,73 %, Gyrodagtylus sp. sebesar 17,02 % dan Tricodina sp. sebesar 18,23%.  Kata kunci: benih ikan lele, ektoparasit, prevalensi, kualitas air.ABSTRACTThe problem in cultivating catfish is disease caused by parasitic infections. The aim of the research was to identify the types of ectoparasites and categorize the level of prevalence, intensity and dominance of ectoparasites in Sangkuriang catfish fry. This research was carried out in July 2022. The method used was random sampling of 80 catfish seeds, checking for ectoparasites and measuring water quality. The ectoparasite identification process was carried out in the Sentani class 1 Fish Control and Quality Quarantine Center laboratory. The results of ectoparasite identification showed three types of parasites, namely Dactylogyrus sp., Gyrodactylus sp., and Trichodina sp.. These ectoparasites attack different organs, namely mucus, gills and fins. The most common parasites found are from the order Monogenea, namely the type Dactylogyrus sp. with a prevalence rate of 60% in the Frequently category (very often). Meanwhile, the ectoparasite with the lowest prevalence is Gyrodactylus sp. and Trichodina sp. with a prevalence rate of 30%. The conclusion of the research is that the average prevalence value of Dagtylogyrus sp. of 48.75%, Gyrodagtylus sp. of 21.25% and Tricodina sp. amounting to 21.25%. Furthermore, the average intensity value of Dagtylogyrus sp. is 2.50 %, Gyrodagtylus sp. is 1.55% and Tricodina sp. is 1.64%. Then the average value of dominance of Dagtylogyrus sp. of 64.73%, Gyrodagtylus sp. amounted to 17.02% and Tricodina sp. amounting to 18.23%.Keywords: catfish seeds, ectoparasites, prevalence, water quality

Abstract

ABSTRAKPengukuran batimetri secara berkala dapat memberikan informasi yang jelas mengenai kondisi perubahan kedalaman perairan sebuah dermaga dimana bertujuan untuk mengetahui kedalaman minimum suatu kapal untuk diperbolehkan berlabuh. Penelitian ini bertujuan untuk mengetahui pola pengendapan sedimen di kolam labuh Koramatim Surabaya serta kajian parameter yang mempengaruhi sebaran sedimen saat kondisi musim barat. Data pengukuran batimetri pada bulan Desember 2022 dan Januari 2023 dianalisis untuk menghasilkan peta tingkat sedimentasi menggunakan metode overlay dengan membandingkan dua model batimetri beda waktu pengukuran yang dilakukan pada aplikasi Civil3D. Data kecepatan dan arah angin pada bulan Desember 2022, Januari 2023 dan Februari 2023 dari BMKG Perak Surabaya akan disajikan dalam bentuk windrose kecepatan dan arah angin dominan yang terjadi pada musim barat tahun 2023. Hasil didapatkan bahwa dominasi pengendapan sedimen terjadi pada pintu masuk kolam labuh Koarmatim Surabaya maksimal 1,62 meter dan rata – rata pada 0,72 meter pada bulan Januari 2023. Indikasi kuat pengaruh dari arah angin dominan yang berhembus dari barat laut mendorong debit buangan sedimen dari sungai Kalimas Surabaya menuju kolam labuh. Penelitian ini masih dapat dilanjutkan untuk melihat bagaimana dinamika pengaruh sungai Kalimas dan arus pasang surut terhadap tingkat sedimentasi di kolam labuh Koarmatim Surabaya pada kondisi seluruh musim. Kata kunci: laju sedimentasi, overlay peta batimetri, angin musim baratABSTRACTPeriodic bathymetry measurements can provide clear information about the changing conditions of the water depth of a dock which aims to determine the minimum depth of a ship to be allowed to dock. This research aims to determine the pattern of sediment deposition in the Koramatim Surabaya dock pond and study the parameters that affect the distribution of sediments during the west season. Bathymetry measurement data in December 2022 and January 2023 were analyzed to provide a sedimentation rate map using the overlay method by comparing two bathymetry models of different measurement times carried out in the Civil3D software. Wind speed and direction data in December 2022, January 2023 and February 2023 from BMKG Perak Surabaya will be presented in the form of windrose of the dominant wind speed and direction that occurred in the west season of 2023. The results showed that the dominance of sediment deposition occurred at the entrance to the Koarmatim Surabaya harbor pond with a maximum of 1.62 meters and an average of 0.72 meters in Januari 2023. A strong indication of the influence of the dominant wind direction blowing from the northwest pushed the discharge of sediment from the Kalimas Surabaya river to the Koarmatim dock. This research can still be continued to see how the dynamics of the influence of the Kalimas river and tidal currents on the level of sedimentation in the Surabaya Koarmatim dock pond under all season conditions.Keywords: sedimentation rate, bathymetry map overlay, westerly winds

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui potensi antibakteri Staphylococcus aureus pada sabun batang dengan bahan baku rumput laut jenis Eucheuma cottonii, penelitian dilakukan di Lab.  FAPERTA Universitas PGRI Banyuwangi. Penelitian dimulai dengan mencari performa terbaik  pembuatan sabun dengan empat perlakuan diantaranya penggunaan E. cottoni sebanyak 15gr (P1), 30gr (P2), 45gr (P3), dan 60gr (P4). Tiap perlakukan dilakukan ulangan sebanyak empat kali kemudian dianalisis ANOVA yang bertujuan untuk menentukan perbedaan signifikan antara perlakuan dan parameter uji pada sabun. Pengujian untuk mengetahui karakteristik sabun diantaranya uji antibakteri pada S. aureus dan uji kimia (kadar air, kadar pH). Hasil penelitian menunjukkan bahwa P4 menghasilkan daya hambat atau luasan zona bening terbesar yaitu 2,4cm.  Analisis statistik menunjukkan perbedaan yang sangat signifikan antara perlakuan, terutama pada perlakuan P1 dan P4. Selain itu, perlakuan P4 juga memiliki kadar air terendah yaitu 26,63% dan pH tertinggi dengan nilai 10,75%. Disimpulkan bahwa E. cottonii berpotensi sebagai antibakteri pada produk sabun dikarenakan adanya kandungan senyawa bioaktif seperti alkaloid, flavonoid, tannin, dan steroid.Kata kunci: Uji Potensi, Antibakteri, Staphylococcus aureus, Sabun, Eucheuma cottoniiABSTRACTThis research aims to determine the antibacterial potential of S. aureus in bar soap made from Eucheuma cottonii seaweed as raw material. The research was carried out in FAPERTA laboratory PGRI University Banyuwangi. The research began by looking for the best performance in soap making with four treatments including the use of 15gr (P1), 30gr (P2), 45gr (P3), and 60gr (P4) E. cottonii. Each treatment was repeated four times and then analyzed by ANOVA which aimed to determine significant differences between treatments and test parameters for soap. Tests to determine the characteristics of soap include antibacterial tests on S. aureus and chemical tests (water content, pH level). The research results showed that P4 produced the largest resistance or clear zone area, namely 2.4 cm.  Statistical analysis showed very significant differences between treatments, especially in treatments P1 and P4. Apart from that, treatment P4 also had the lowest water content, namely 26.63% and the highest pH with a value of 10.75%. It was concluded that E. cottonii has the potential to act as an antibacterial in soap products due to the content of bioactive compounds such as alkaloids, flavonoids, tannins and steroids.Key words:  Potency Test, Antibacterial, Staphylococcus aureus, Soap, Eucheuma cottonii
