Abstract Sea weed is a great culture commodity with high economical value. The purpose of this Field Job Practice were to get knowledge and skill ,the constraint, and also the opportunity to develop it. This Field Job st thPractice performed in Tanjung Village at July 31 until September 10 2006 used description method. Sea weed culture techique use flouting raft with raft size 7 x 10 m and string distance 14 cm with culture 30 days period. The constraint are pest attack like Baronang (Siganus sp.), ice ice, white spot disease and also weather fluctuation.This culture has opportunity to develop because it has fast cash back about 2,176 periode.

Different Doses

This study was aimed at assessing the carrageenan content and the growth of seaweed K. alvarezii in white spot disease infection conditions with different doses of NPK in Banggai waters. Results showed that all doses could increase the carrageenan content of the white spot-infected seaweed, with the highest content in treatment D (25 g of NPK/ 10 liters of water), 43.862 ± 19.546, followed by C (20 g of NPK /10 liters of water) 35.685 ± 14.693, B (15 g of NPK/10 liters of water), 23.208 ± 5.992, A (10 g of NPK/10 liters of water),19.132 ± 4.405, and K (without dose), 10.225 ± 2.782, respectively. The highest growth was recorded in treatment D, 401.333 ± 3.215 g, followed by treatment C, 310.000 ± 6.000 g, B, 7.211 g ± 298.000+ 7.211 g, A, 256. 667 ± 11.547 g, and the lowest in control treatment, 218.000 ± 9.849 g, respectively. Penelitian ini bertujuan untuk mengkaji kandungan karaginan dan pertumbuhan dari rumput laut K. alvarezii pada kondisi terkena penyakit white spot dengan dosis NPK yang berbeda di Perairan Kabupaten Banggai. Hasil percobaan menunjukkan bahwa semua dosis mampu meningkatkan kandungan karaginan pada rumput laut yang terinfeksi white spot. Kandungan tertinggi terdapat pada perlakuan D (dosis NPK 25 g/10 liter air) yaitu 43.862±19.546, diikuti perlakuan C (dosis NPK 20 g/10 liter air) 35.685±14.693, B (dosis NPK 15 g/10 liter air) 23.208±5.992, A (dosis NPK 10 g/10 liter air) 19.132±4.405 dan K (tanpa dosis) 10.225±2.782. Pertumbuhan tertinggi terdapat pada perlakuan D yaitu sebesar 401.333 ± 3.215 gram, kemudian diikuti oleh perlakuan C 310.000 ± 6.000 gram, B 298.000 ± 7.211 gram, A sebesar 256.667 ± 11.547 gram, dan terendah pada perlakuan kontrol yaitu sebesar 218.000 ± 9.849 gram.

Title (Bahasa Indonesia): Pengaruh pupuk NPK [nitrogen, fosfor, kalium] terhadap pertumbuhan dan penanggulangan penyakit ‘white spot’ pada rumput laut Kappaphycus alvarezii This study aimed to analyze the effect of NPK fertilizer absorption on the growth of seaweed, Kappaphycus alvarezii, and the white spot disease prevention. This study could become a source of information for seaweed farmers to increase seaweed production through the use of NPK fertilizers. This study was conducted from January until March, 2014 in the waters of Toropot Village, the District of Bokan Islands, Banggai Laut. To know whether the different doses affect the white spot infection, ANOVA with Tukey's test was used. Results showed that all doses had the same potential to recover from white spot disease and heal faster than the control (no dose). The addition of nutrients N, P, and K at high dose could accelerate the recovery of the algae from white spot desease and increase the growth rate. Penelitian ini bertujuan untuk menganalisis pengaruh penyerapan pupuk NPK terhadap pertumbuhan dan penanggulangan penyakit white spot pada rumput laut Kappaphycus alvarezii. Penelitian ini dapat sebagai sumber informasi bagi pembudidaya rumput laut untuk meningkatkan produksi rumput laut melalui penggunaan pupuk NPK. Penelitian ini dilaksanakan mulai Januari sampai Maret 2014 di perairan Desa Toropot, Kecamatan Bokan Kepulauan, Kabupaten Banggai Laut. Untuk mengetahui apakah perbedaan dosis memberikan pengaruh terhadap serangan white spot, maka dilakukan pengujian ANOVA dengan uji Tukey. Hasil menunjukkan bahwa bahwa semua dosis memiliki potensi yang sama untuk memulihkan penyakit white spot dan lebih cepat penyembuhannya dari kontrol (tanpa dosis). Penambahan nutrien N, P dan K pada dosis tinggi dapat mempercepat pemulihan alga dari penyakit white spot dan dapat meningkatkan laju pertumbuhannya.
