UTILIZATION OF MANGROVE FRUIT (RHIZOPORA sp) AS AN ACTIVE INGREDIENT IN MAKING BODY SCRUB PREPARATION
Full text linkBody scrub is a cosmetic product that can remove dead skin cells, brighten the skin, and exfoliate dead skin cells in the stratum corneum. Body scrubs can be made from several types of plants, one of which is mangrove fruit. The purpose of this research is to create a body scrub that can moisturize the skin and contain high levels of antioxidants.This study was conducted on 4 treatments with the addition of mangrove (Rhizophora sp), namely F0 (Control), F1 (10% mangrove), F2 (15% mangrove) and F3 (20% mangrove). From the hedonic test conducted on 30 woman panelists aged 17-25 years, it was found that the sample that obtained the highest score was F1. Based on the results of the homogeneity test, it is known that all treatments in this study showed that the body scrub produced from this study was homogeneous. The results of the pH test showed that all body scrub preparations met the skin pH criteria, 4.5-7. Skin moisture after being smeared for 5 days with body scrub increased every days.The results of the irritation test for each test sample showed negative results, The results of the antioxidant test (IC50) in F0 (Control) were 86664.78 mg/kg, in F1 (Addition of 10% mangrove) the IC50 value was 696.41 mg/kg, this shows that the addition of mangrove (Rhizophora sp) has a significant effect on the antioxidant activity of the body scrub preparation. This research proves that Rhizophora sp mangrove can be used as a body scrub preparation
HUBUNGAN PENGGUNAAN TRY NET TERHADAP JUMLAH HASIL TANGKAPAN UTAMA JARING HELA UDANG BERKANTONG
Full text linkPerairan Laut Arafura merupakan sentra utama penangkapan udang di Indonesia, sehingga efisiensi operasi jaring hela udang berkantong menjadi sangat penting mengingat ketidakpastian lokasi stok sering memicu pemborosan bahan bakar, waktu towing, serta meningkatnya risiko bycatch. Penggunaan try net sebagai alat tes awal semakin umum untuk memperkirakan keberadaan dan kepadatan udang sebelum jaring utama dioperasikan. Penelitian ini bertujuan menganalisis hubungan antara hasil try net dan hasil tangkapan jaring utama serta mengevaluasi bagaimana informasi tersebut memengaruhi pengambilan keputusan nakhoda di lapangan. Penelitian dilakukan secara on board pada KM. Binama 02 di Laut Arafura (Januari–Maret 2024) dengan mengumpulkan 90 pasang data hasil try net dan jaring utama. Analisis regresi linear sederhana digunakan untuk menilai hubungan kedua variabel, disertai observasi pola keputusan nakhoda menggunakan pendekatan decision analysis. Hasil penelitian menunjukkan korelasi positif signifikan antara hasil try net dan tangkapan utama (r = 0,642; R² = 0,4127). Persamaan regresi Y = 146,02 + 8,61X mengindikasikan bahwa setiap tambahan satu ekor pada try net berpotensi meningkatkan 8–9 ekor tangkapan utama. Keputusan nakhoda terbagi dalam tiga pola: mempertahankan haluan saat hasil tinggi, mengubah haluan kecil saat hasil menurun, dan putar balik ketika try net kosong. Penelitian ini menegaskan try net sebagai indikator operasional efektif yang meningkatkan efisiensi penangkapan dan mendukung strategi navigasi adaptif dalam pengelolaan perikanan udang secara berkelanjutan.The Arafura Sea is Indonesia’s primary shrimp fishing ground, making the efficiency of bagged shrimp trawl operations critically important, as uncertainty regarding stock location often leads to fuel waste, extended towing time, and increased bycatch risk. The use of a try net as a preliminary testing gear has become increasingly common to estimate the presence and density of shrimp before deploying the main net. This study aims to analyze the relationship between try-net results and the main trawl catch, and to evaluate how this information influences skippers’ decision-making in the field. The research was conducted on board KM. Binama 02 in the Arafura Sea (January–March 2024) by collecting 90 paired observations of try-net and main-net catches. Simple linear regression analysis was applied to assess the relationship between the two variables, supplemented by observations of skipper decision patterns using a decision-analysis approach. The findings revealed a significant positive correlation between try-net results and main-net catches (r = 0.642; R² = 0.4127). The regression equation Y = 146.02 + 8.61X indicates that each additional shrimp caught in the try net potentially increases the main catch by 8–9 shrimp. Skippers’ decisions were categorized into three patterns: maintaining course when results were high, making minor course adjustments when results declined, and reversing course when the try net yielded no shrimp
THE EFFECT OF THYROXINE HORMONE AND RECOMBINANT GROWTH HORMONE (RGH) SOAKING ON THE RATE OF EGG YOLK ABSORPTION AND GROWTH OF TAWES FISH (Barbonymus gonionotus)
Full text linkTawes fish (Barbonymus gonionotus), also known as lampan, is an indigenous freshwater species with significant economic value and cultivation potential. However, suboptimal growth remains a common challenge in aquaculture. Hormonal treatments such as thyroxine and rGH are known to enhance metabolic processes, potentially improving egg yolk absorption and larval growth. This study aimed to evaluate the effects of thyroxine and rGH hormone immersion on the rate of egg yolk absorption and development of newly hatched tawes fish larvae. The experimental design employed a CRD with four treatments and three replications: A (thyroxine 0 mg/L + rGH 2.5 mg/L), B (thyroxine 0.1 mg/L + rGH 0 mg/L), C (thyroxine 0 mg/L + rGH 2.5 mg/L), and D (thyroxine 0.1 mg/L + rGH 2.5 mg/L), with hormone immersion conducted for 60 minutes. The results demonstrated that the combined immersion of thyroxine and rGH significantly (P <0.05) improved the absolute weight gain, absolute length increment, and survival rate of tawes fish larvae. The highest values for absolute weight (0.043±0.002 g) and length (12.77±0.15 mm) were observed in treatment D (thyroxine 0.1 mg/L + rGH 2.5 mg/L), while the best survival rate (70.00±2.00%) was recorded in treatment A (thyroxine 0 mg/L + rGH 2.5 mg/L). These findings suggest that the combined use of thyroxine and rGH can effectively enhance the early growth and development of tawes fish larvae
SPECIES IDENTIFICATION AND GENETIC DIVERSITY OF PORTUGUESE OYSTER (Crassostrea angulata): IMPLICATIONS FOR BREEDING IN VIETNAM
Full text linkCupped oyster has emerged as the predominant mollusk farmed domestically in Vietnam because of its exceptional adaptability to the local subtropical and tropical climates. However, considerable confusion remains regarding the identity of the cultivated species due to the taxonomic ambiguity between Portuguese cupped oyster (Crassostrea angulata) and Pacific cupped oyster (Crassostrea gigas). This study aims to clarify the species identity of the most commonly farmed cupped oysters in Vietnam and to evaluate genetic diversity and the suitability of oyster strains for a breeding program including three Vietnamese strains (Quang Ninh, Khanh Hoa, and Vung Tau) and one wild population from Taiwan. Based on mitochondrial DNA cytochrome c oxidase subunit I (COI) sequences, our results confirmed that all samples in Vietnam and Taiwan are C. angulata. Furthermore, this study performed genetic analyses using mtCOI sequences and five microsatellites. Populations in Vietnam and Taiwan maintain high levels of genetic diversity, with the average number of alleles per population varied between 7.80 to 16.0, and there was no statistical difference between observed and expected heterozygosity (P > 0.05), except in the hatchery population Vung Tau. The samples collected from this population suffered a great loss of heterozygosity and occupied the highest Fis value (Fis = 0.3), which is likely due to the small size of founding stock and long-term artificial breeding by local hatchery farmers, resulting in a strong genetic bottleneck and inbreeding depression. Pairwise FST calculated by microsatellites with a range of 0.043 to 0.093 revealed significant (P < 0.05) levels of genetic differentiation among oyster lines. Collectively, our findings clarify the taxonomic status of farmed oysters in Vietnam and highlight the importance of crossing among different strains in future breeding programs to maximize the genetic gain and avoid inbreeding, especially when using the oyster strain from Vung Tau
