Proteins play a vital role in life as essential macromolecules, consisting of linear heteromeric biopolymers formed by amino acids covalently bonded through peptide bonds. They contribute to cell development and bolster the body's defense mechanisms. Post-translational modification processes, such as glycosylation, are necessary for proteins to function optimally. Glycosylation involves adding sugar groups to proteins, playing a critical role in various protein folding processes. Dysregulation of protein glycosylation can lead to diseases like Alzheimer's and cancer. Manual classification of glycosylated proteins is time-consuming, necessitating a faster approach. This study aims to expedite glycosylated protein classification using novel methods like AAindex, CTD, SABLE, hydrophobicity, and PseAAC for increased accuracy, comparing them with existing approaches. The dataset comprises protein sequences sourced from the openly accessible UniProt database. Results demonstrate that glycosylated protein prediction achieved 100% accuracy, surpassing previous approaches. Several features contributed to this improvement, with Hydrophobicity making a significant contribution at 24%, and PseAAC making the most significant contribution at 40% among the five extraction methods developed.

This study evaluates the hematological profile of potential broodstock silver pompano (Trachinotus blochii) through hormonal induction and phyto-biotic supplementation via feed. An experimental trial was conducted for 30 days to assess the hematological profile of potential broodstock Trachinotus blochii. This study employed a completely randomized design (CRD) in two research experiments. The first experiment utilized hormonal induction with estradiol-17β hormone on female silver pompano broodstock, consisting of 3 treatments: E1 (0 mg/kg), E2 (20 mg/kg), and E3 (60 mg/kg), whereas the second experiment employed phyto-biotic induction using Tribulus terrestris extract (ETT) and gonadotropin hormone, consisting of 5 treatments: T1: ETT 0 mg/kg feed, T2: ETT 50 mg/kg feed, T3: ETT 250 mg/kg feed, T4: ETT 50 mg/kg feed + gonadotropin 1000 IU/kg body weight, and T5: ETT 250 mg/kg feed + gonadotropin 500 IU/kg body weight, both experiments used 8 individuals as replicate per treatment. The results of the study indicated that all major hematological indices such as total erythrocytes, total leukocytes, and hematocrit levels were higher in male silver pompano broodstock supplemented with Tribulus terrestris extract compared to female silver pompano broodstock induced hormonally with estradiol-17β hormone.

Silver pompano (Trachinotus blochii) is a mariculture commodity with fast growth characteristics and easy adaptation to the environment. However, the production of its seeds is hindered by the maturation of the parent's gonads out-side the spawning season. Hormonal approaches are needed for the maturation of the parent's gonads. The aim of this study is to investigate the level of steroid hormones, gonadosomatic index, and gonad histology in female silver pompano (Trachinotus blochii) broodstock after dietary supplementation with 17-estradiol. This research is crucial for the advancement of effective and efficient techniques for rearing this fish. The study used a completely randomized design (CRD) consisting of three different 17estradiol concentrations (0 mg/kg (E1), 30 mg/kg (E2), and 60 mg/kg (E3) fed to female silver pompano broodstock for 30 days, beginning at initial feeding, each with eight individual replicates. Absolute body weight growth, steroid hormone levels, gonadal maturation index, gonadal histology, fecundity, and egg diameter of female silver pompano broodstock were all examined in this study. The incorporation of 17-estradiol hormone into the sustenance amplifies the reproductive capabilities of the female silver pompano broodstock. The inclusion of 17-estradiol hormone in the diet renders the most elevated values regarding fecundity and egg diameter in the female silver pompano broodstock. Histological examinations expose that the development of the gonads in the female broodstock treated with 17-estradiol hormone progresses towards maturation. The inclusion of 17- estradiol hormone in the diet at doses of 20 and 60 mg/kg feed yields the highest values in terms of fecundity and egg diameter in female silver pompano broodstock.Keywords:17-estradiolGonadal histologyGonadosomatic indexSteroid hormoneSilver pompano

Budidaya ikan di keramba jaring apung idealnya dilakukan sesuai dengan prinsip ekonomi biru sambil tetap menjaga kelestarian ekosistem. Tujuan penelitian ini untuk sejauh mana prinsip ekonomi biru diterapkan dan penjagaan kelestarian ekosistem pada budidaya ikan KJA di Kecamatan Teluk Pandan, Kabupaten Pesawaran, Provinsi Lampung pada bulan Juli – September 2024. Data dikumpulkan dengan cara wawancara mendalam, observasi dan studi pustaka, selanjutnya dianalisis untuk mengukur sejauh mana prinsip tersebut diterapkan. Hasil penelitian menunjukkan bahwa sebagian besar pembudidaya ikan tidak mengenal istilah "ekonomi biru". Namun beberapa prinsip ekonomi biru, seperti memajukan pertumbuhan ekonomi, memperbaiki kesejahteraan sosial dan menjaga ekosistem laut, telah diimplementasikan meski belum sepenuhnya optimal. Contohnya adalah upaya pembudidaya dalam tidak membuang sampah sembarangan dan menggunakan pakan sesuai padat tebar optimal. Diperlukan bimbingan teknis yang intensif untuk memperkuat penerapan prinsip ekonomi biru pada usaha budidaya ikan dengan sistem KJA.
