Penelitian ini bertujuan untuk menentukan performa bibit rumput laut K. alvarezii hasil seleksi varietas Takalar, SIRICA, dan Bali. Desain penelitian adalah rancangan acak lengkap (RAL), dengan empat siklus pemeliharaan sebagai ulangan. Seleksi bibit dilakukan pada ketiga varietas dengan bibit non-seleksi sebagai kontrol internal. Pemeliharaan dilakukan di perairan Laikang, Takalar, Sulawesi Selatan selama empat siklus dengan durasi 30 hari/siklus. Pengukuran laju pertumbuhan harian (LPH), kandungan karagenan, kekuatan gel, dan monitoring kualitas air dilakukan setiap 30 hari. Data yang diperoleh dianalisis menggunakan analisis ragam (ANOVA). Hasil penelitian menunjukkan bahwa seleksi bibit berpengaruh signifikan terhadap LPH rumput laut (P<0,05). Rumput laut hasil seleksi memiliki LPH lebih tinggi, yakni: Bali (4,75 ± 0,04%/hari), SIRICA (4,74 ± 0,06%/hari), dan Takalar (4,62 ± 0,12%/hari) dibandingkan dengan kontrol internal Bali (3,94 ± 0,15%/hari), SIRICA (3,74 ± 0,10%/hari), dan Takalar (3,66 ± 0,32%/hari). Rumput laut hasil seleksi varietas Bali dan SIRICA memiliki kandungan karagenan yang relatif sama yakni (37,27 ± 6,68%) dan (37,08 ± 7,17%). Varietas Takalar memiliki kandungan karagenan yang rendah (31,84 ± 5,32%) namun memiliki kekuatan gel yang paling tinggi (570,03 ± 145,72 g/cm²) dibandingkan varietas Bali (444,39 ± 157,44 g/cm²) dan SIRICA (438,48 ± 72,70 g/cm²).Regeneration by selection method can improve the quality of seaweed seed. This study was aimed to determine the performance of selected seaweed seeds of K. alvarezii from Takalar, SIRICA, and Bali varieties. The experiments were arranged in a completely randomized design with four cycles cultivations as replications. In each variety, a batch of non-selected/regular seeds was cultivated serving as internal control. The seaweed was cultivated in Laikang waters, Takalar Regency, South Sulawesi for 30 days for each cycle. The measurements of daily growth rate (DGR), carrageenan yield, gel strength, and water quality were conducted every 30 days. The collected data were statistically analyzed using ANOVA. The results showed that the selected seeds showed faster growth than that of its respective control (P<0.05). The selected seed of three varieties of K. alvarezii had higher DGR: Bali (4.75 ± 0.04%/day), SIRICA (4.74 ± 0.06%/day), and Takalar (4.62 ± 0.12%/day) than that of control varieties, Bali (3.94 ± 0.15%/day), SIRICA (3.74 ± 0.10%/day), and Takalar (3.66 ± 0.32%/day). The selected seeds of Bali and SIRICA had similar carrageenan content (37.27 ± 6.68%) and (37.08 ± 7.17%), respectively. Takalar had the lowest carrageenan yield (31.84 ± 5.32) but had the highest gel strength (570.03 ± 145.72 g/cm²) compared to Bali (444.39 ± 157.44 g/cm²) and SIRICA (438.48 ± 72.70 g/cm²).

Kappaphycus alvarezii cultivation by the verticulture method has been introduced since 2013. However, scientific studies on some technical aspects are still needed to improve the quality, quantity, and continuity of production and utilization of area in a maximum and productive manner. One of them is the planting distance between seed clumps. The purpose of this study was to determine the optimal planting distance between seed clumps on seaweed verticulture method. Seaweed was cultured using a 10x10 m2 floating raft containing 36 vertical nets of 5x2 m2/net. Seaweed seeds with an initial weight of 50 g were tied to a vertical net with a distance between knot on the verticulture net of 15 cm, 25 cm, and 35 cm. Seaweed cultivation was done for 3 cycles (1 cycle = 45 days) continuously in the cycle of planting season. The experimental units were prepared with Completely Randomized Design (RAL) with 3 replications. The results showed that daily growth rate (DGR) and carrageenan content of seaweed planted with a distance of 15 cm, 25 cm, and 35 cm between clumps were not significantly different (P>0.05). However, it is recommended to apply 25 cm distance between seed clumps in the verticulture method.

The mortality of tinfoil barb during transportation is relatively high due to the oxygen consumption rate and excretion of these fishes. Therefore, the use of an appropriate anesthetic drug becomes one of the solutions for solving this transportation problem of tinfoil barb. One of the natural anesthetic drugs with potential to be studied is Chromolaena odorata leaves. The purpose of this study is to evaluate the effectiveness of anesthetic compounds from Chromolaena odorata leaves in the closed transportation of tinfoil barb. The experimental design used was a non-factorial completely randomized design that consisted of four treatments and three replications,then followed by a Tukey test to see if there was a significant difference. The experimental treatments were A (0 ml/L of leaves filtrate), B (80 ml/L of leaves filtrate), C (90 ml/L of leaves filtrate), and D (100 ml/L of leaves filtrate). The observed parameters were fish behavior towards unconscious condition, onset time, immotilization time, survival rate, and water quality. The results showed that the shortest onset time was obtained from treatment D (100 ml/L leaves filtrate), namely 58 minutes towards unconscious condition, then the longest immotilization time was also shown by treatment D, which was 371 minutes. The highest survival rates were also shown by treatment D which were 94,33% during transportation and 76,33% during culture. The water quality parameters during the experiment were in an optimum condition of tinfoil barb. Keywords:AnestheticChromolaenaodorataTransportationTinfoil barb
