Abstract

upaya untuk mengurangi kadar lemak tersebut. Tujuan penelitian ini adalah mengevaluasi suplementasi L-karnitin dan tepung kayu manis terhadap kadar lemak dan tekstur daging ikan patin pada fase pembesaran. Ikan patin berukuran 125,4 ± 7,85 g dan panjang 24,71±0,68 cm dipelihara selama 60 hari dalam wadah hapa berukuran 2 x 1 x 1 m3. Ikan diberi pakan tiga kali sehari ad satiation dengan perlakuan, sebagai berikut: kontrol (K), penambahan L-karnitin 1 g kg-1 (LK 1), L-karnitin 2 g kg-1 (LK 2), kayu manis 5 g kg-1 (KM 5), dan kayu manis 10 g kg-1 (KM 10). Sampel diambil pada awal, pertengahan, dan akhir pemeliharaan untuk pengukuran kadar lemak daging. Parameter yang diamati yaitu lemak daging dan tekstur daging. Hasil menunjukkan bahwa pemberian KM 10 menghasilkan kadar lemak yang lebih rendah dari perlakuan lainnya setelah 30 hari dan penurunan yang lebih besar yaitu berkisar 51,06% dan 42,55% pada perlakuan LK 2 dan KM 10 pada hari ke-60. Nilai indeks hepatosomatik juga menurun yang diikuti oleh penurunan kadar lemak hati. Nilai kekerasan daging menunjukkan peningkatan kualitas yang terlihat dari nilai yang semakin rendah. Pemberian tepung kayu manis 10 g kg-1 pada fase pembesaran menunjukkan hasil terbaik pada pemberian selama 60 hari dalam menurunkan lemak daging ikan patin hingga memenuhi standar filet, karena adanya proses lipolisis serta pemanfaatan lemak menjadi energi. Kayu manis ini menjadi sangat potensial untuk dikembangkan sebagai feed additive dalam upaya memperbaiki kualitas daging ikan patin fase pembesaran.Striped catfish meat has a high-fat content which is undesirable to markets and customers alike and needs to be reduced. This study aims to evaluate the effect of dietary L-carnitine and cinnamon powder on reducing the fat content of striped catfish meat in the grow-out stage. Striped catfish measuring 125.4 ± 7.85 g and 24.71 ± 0.68 cm body length were kept for 60 days in a hapa with size 2 x 1 x 1 m3. Thefish were fed three times a day at satiation with the following treatments: control (K), the addition of L-carnitine 1 g kg-1 (LK 1), L-carnitine 2 g kg-1 (LK 2), cinnamon 5 g kg-1 (KM 5) and cinnamon 10 g kg-1 (KM 10). Sampling was conducted on the initial, middle and final day for meat fat content analysis. The parameters observed were meat fat and meat texture. The results showed that dietary KM 10 significantly reduced meat fat content compared to controls on the 30th and it showed a more significant reduction, namely 51.06% and 42.55%, in the treatment LK 2 and KM 10 after 60 days treatment. The hepatosomatic index value also decreased, followed by decreased liver fat levels. The lower values of meat hardness imply an increase in meat quality. It can be concluded that the application of dietary cinnamon powder at 10 g kg-1 (KM 10) is the best level to reduce the fat content of striped catfish meat in meeting the fillet standards. This cinnamon has excellent potential to be developed as a feed additive to improve the quality of striped catfish meat in the rearing phase.

Abstract

Efficient dietary protein utilization is essential to reduce feed costs and environmental impacts in sustainable aquaculture. This study aimed to evaluate the effects of cinnamaldehyde (CA) supplementation in feed with various energy-to-protein (E:P) ratios on the chemical composition of Pangasianodon hypophthalmus. The five feed formulas that made up the treatment feed were as follows: 28:13-C0 (28 % Protein with an E:P ratio of 13 and CIN 0 g kg-1); 25:14-C1 (25 % protein with an E:P ratio of 14 and CIN 1.2 g kg-1); 25:14-C2 (25 % protein with an E:P ratio of 14 and CIN 1.7 g kg-1); 25:15-C1 (25 % protein with an E:P ratio of 15 and CIN 1.2 g kg-1); and 25:15-C2 (25 % Protein with an E:P ratio of 15 and CIN 1.7 g kg-1). Striped catfish weighing 28.06 ± 0.19 g were placed in a hapa (2 × 1 × 1 m3) at a density of 25 fish per cage. Fish were fed to apparent satiation three times daily for 60 d. The 25:14-C2, 25:15-C1, and 25:15-C2 diets increased albumin levels and reduced cholesterol, while 25:15-C2 also yielded the highest total protein and lowest triglyceride levels. Growth performance and feed efficiency were comparable among 28:13-C0, 25:14-C2, 25:15-C1, and 25:15-C2 (final weight: 141.62–143.75 g; FCR: 1.16–1.19). Protein efficiency ratio was highest in 25:15-C1 and 25:15-C2, whereas protein retention peaked in 25:14-C2. The hepatosomatic index was elevated in 25:14-C1, 25:14-C2, and 25:15-C1. Body lipid content was highest in 25:15-C1, while muscle lipid content was lowest in 25:14-C2 and 25:15-C1. Reducing dietary protein from 28 % to 25 % did not compromise growth performance at the E:P ratio level of 15 with a supplementation of 1.2 g kg-1 CIN.

Abstract

Ikan gurame (Osphronemus gouramy) memiliki nilai ekonomi tinggi, namun sintasan larvanya masih rendah akibat infeksi patogen dan kondisi lingkungan yang sensitif. Penelitian ini bertujuan mengkaji pengaruh perendaman larva ikan gurame dengan menggunakan simplisia kunyit (Curcuma domestica) sebagai agen antimikroba alami untuk meningkatkan kesehatan larva. Rancangan percobaan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) yang terdiri atas tiga perlakuan: kontrol, P1 (30 mg/L simplisia kunyit pada media), dan P2 (30 mg/L pada media serta pakan cacing sutera direndam 1 g/L), masing-masing tiga ulangan. Parameter yang diamati terdiri dari pertumbuhan panjang mutlak, prevalensi jamur, sintasan, dan kualitas air selama empat minggu. Berdasarkan hasil analisis, tidak terdapat perbedaan yang nyata pada pertumbuhan antar perlakuan (P > 0,05). Prevalensi jamur menurun pada P1 (5,16%) dan P2 (4,01%) dibandingkan kontrol (15,71%), menegaskan aktivitas antijamur kunyit. Sintasan berkisar 74,44–82,22% tanpa perbedaan signifikan. Kualitas air tetap dalam kisaran layak. Secara umum, simplisia kunyit efektif menekan jamur tetapi belum meningkatkan pertumbuhan dan sintasan, sehingga diperlukan formulasi yang lebih efisien.

Abstract

The Green Severum Heros appendiculatus is a species of freshwater ornamental fish originating from the northern United States. Currently, its aquaculture industry is expanding due to its high economic value, which is expected to contribute to community welfare by creating job opportunities and increasing export value. This study aims to disseminate technical information on Green Severum breeding, as limited data is available on its cultivation management. Technically, this fish can be used as broodstock at 10–14 months of age, with a sex ratio of 1 male to 1 female. During the breeding period, broodstock is fed natural feed, including Tubifex sp. (silk worms) and Lumbricus sp. (earthworms). The spawning process occurs naturally using PVC pipes as spawning substrates. The study results indicate that the average fertilization rate (FR) is 90%, the hatching rate (HR) is 95%, and the survival rate (SR) is 93%.

Abstract

Background: Diatoms require silicate for frustule formation and optimal cell division, making silicate availability a critical factor in improving microalgal production for aquaculture. Thalassiosira sp. is one of the most widely used live feeds in shrimp hatcheries because of its high nutritional value and suitable cell size for larval consumption.Aims: This study evaluated the effects of different silicate concentrations on the growth performance of Thalassiosira sp. by simultaneously assessing cell density, specific growth rate (SGR), and division rate (DR).Methods: A completely randomized design with four treatments was employed: control (without silicate), 15 ppm (SL15), 20 ppm (SL20), and 25 ppm (SL25), each with three replicates. Cell density was monitored daily for 14 days using a haemocytometer, while SGR and DR were calculated from the exponential growth model.Results: The results showed that silicate supplementation significantly affected all growth parameters (p < 0.05). The highest cell density (4.60 × 10⁶ cells mL⁻¹) was obtained in the SL25 treatment on day 12, whereas the highest SGR (29.17 ± 0.32% day⁻¹) and DR (0.422 ± 0.005 divisions day⁻¹) were recorded in SL20. However, Duncan's Multiple Range Test indicated no significant differences between SL20 and SL25 for SGR and DR, suggesting comparable physiological responses at these silicate concentrations. These findings indicate that silicate concentrations between 20 and 25 ppm provide the optimal range for enhancing the growth performance of Thalassiosira sp. and may improve the efficiency of live-feed production for shrimp hatchery applications.Conclusion: Silicate supplementation significantly improve the growth performance of Thalassiosira sp., as reflected by increased cell density, specific growth rate, and division rate.

Abstract

The shift of the state's center of gravity into the digital domain has created new vulnerabilities, where disruptions to cyber infrastructure may lead to national paralysis. This study examines the governance of cyber technology and digital infrastructure as National Vital Objects within the framework of Law No. 23 of 2019 on the Management of National Resources for State Defense (UU PSDN). A systems thinking approach was employed using Causal Loop Diagrams (CLD) and SWOT/TOWS analysis to identify the institutional factors underlying the gap between high cyber threat intensity and weak compliance enforcement. The findings reveal that cyber technology and digital infrastructure conceptually and operationally qualify as Artificial Resources and National Vital Objects but lack legal certainty due to the absence of the Government Regulation mandated by Article 56 of the UU PSDN. This regulatory gap weakens the implementation of Article 59 on asset maintenance and reduces the effectiveness of cyber detection and response mechanisms. The TOWS analysis positions Indonesia in a turn-around strategic posture emphasizing internal institutional consolidation. The study recommends accelerating the issuance of the Government Regulation, harmonizing it with Presidential Regulation No. 82 of 2022, establishing mandatory incident reporting and administrative sanctions, allocating a minimum cybersecurity budget, expediting the Cyber Security and Resilience Bill, and institutionalizing a Cyber Reserve Component through professional partnerships.
