Abstract

This research seeks to determine the organoleptic quality of fresh vaname shrimp which are marketed in modern market of Makassar City. The research was conducted from December 2019 to February 2020, in three modern markets with each representing the eastern, central, and western parts of Makassar. Samples were taken three times in each market during 10.00-11.00. The organoleptic testing consisted several parameters; appearance, smell, and meat/texture, and was performed at the Laboratory of Fisheries Product Quality Implementation Agency (BPMPP) of South Sulawesi Province. In addition, shrimp temperature and pH tests were performed shortly after sampling. The data obtained were analyzed descriptively and presented in tabular form. The research results showed that vaname shrimp marketed in three modern markets of Makassar City were categorized as fresh shrimp which were within the safe limit for consumption. Compared to the Indonesian National Standard (01-2728.1-2018) regarding the organoleptic safety of fresh shrimp, this results showed values meeting safety standards. Keywords: Organoleptic quality, vaname shrimp, modern market

Abstract

Literasi merupakan keterampilan yang dibutuhkan dalam kehidupan sehari-hari yang dapat dikembangkan melalui proses pembelajaran berkelanjutan dan stimulasi sejak usia dini. Pada konteks kelautan dan perikanan, literasi menjadi aspek penting untuk menumbuhkan kesadaran akan keberlanjutan ekosistem laut, terutama bagi generasi muda. Oleh karena itu, kegiatan pengabdian ini bertujuan untuk meningkatkan literasi kelautan dan perikanan pada anak-anak di Yayasan Rumah Harapan Banjarmasin cabang Kilometer 1 melalui pendekatan edukasi dan kreasi. Kegiatan di Banjarmasin melibatkan anak-anak usia 5-12 tahun. Metode yang digunakan meliputi pemberian materi, wawancara, observasi, permainan edukatif, mewarnai, dan pre/post test. Evaluasi dilakukan dengan analisis deskriptif kualitatif melalui wawancara mendalam dan kuisioner.. Kegiatan pengabdian di Yayasan Rumah Harapan cabang Kilometer 1 Banjarmasin berhasil meningkatkan literasi kelautan dan perikanan anak-anak. Hasil pre dan post test menunjukkan peningkatan signifikan, terutama pada kelompok usia 9–12 tahun, dari rata-rata 60 menjadi 80. Anak-anak usia 4–6 tahun juga menunjukkan peningkatan pemahaman. Selain itu, observasi saat kegiatan memperlihatkan antusiasme tinggi, diskusi aktif, dan kesadaran akan pentingnya menjaga laut. Program ini efektif membangun fondasi awal pengetahuan maritim yang penting bagi generasi muda pesisir. Kesimpulannya, metode edukatif berbasis interaktif dan kreatif terbukti efektif dalam menanamkan kesadaran serta meningkatkan literasi kelautan pada anak-anak sejak usia dini. Kegiatan ini efektif meningkatkan literasi dan kesadaran anak-anak tentang pentingnya menjaga laut, dibuktikan dengan hasil post test meningkat.

Abstract

Highlight Research Immersion of tuna skin using NaHCO3 at low temperatures effectively reduces the fat content. The DH value, MW, and amino acid composition are in line with the antioxidant activity of tuna skin hydrolysate. The ABTS method showed the highest antioxidant activity in tuna skin hydrolysate. FPH of tuna skin shows functional group characteristics and amino acid composition that are similar to collagen hydrolysate products. FPH of tuna skin has the potential as a source of antioxidants, ACE inhibitors, and antifibrinolytics. Abstract The tuna fillet industry produces abundant skin by-products with high protein, which has the potential as a raw material for fish protein hydrolysate (FPH) for a source of bioactive peptides. Exploration of bioactive peptides from fish skin is generally from hydrolyzed gelatin and collagen. The study aimed to produce FPH directly from tuna skin as an antioxidant and identify potential bioactive peptides. The research began by defatting using multiple concentrations of NaHCO3 and immersion times. The defatted fish skin was produced as FPH by enzymatic hydrolysis method using different papain enzyme concentrations and hydrolysis times. The selected treatments were assessed for antioxidant activity and bioactive peptides. The results showed that the defatting process using a 0.50% NaHCO3 for 30 minutes generated the highest reducing fat content in value was 80.53%. Using papain enzyme gave a significant effect on the DH of FPH, with value was 29.72-67.64%. Therefore, FPH obtained from different concentrations for 4 hours was chosen to characterize the antioxidant activity and bioactive peptide. Hydrolysis using 5% enzyme papain showed the highest antioxidant activity of DPPH, ABTS, and reducing power with values of 0.965 mg/mL, 0.495 mg/mL, and 0.415 absorbances, respectively. FPH possesses a molecular weight of 10.15-48.50 kDa. Functional groups detected were amides A, B, I, II, and III. Glycine, proline, and arginine became amino acids dominant of FPH. Based on the diversity of biopeptide compounds, several biological function candidates were detected, namely antioxidants, ACE inhibitors, and antifibrinolytics which have the potential to be used as nutraceutical products.
