Penelitian tahap 2 diperoleh kadar NO tertinggi oleh kelompok K+ 134,81 μmol/L, sedangkan kadar NO terendah oleh kelompok K- 38,67 μmol/L. Pemberian hidrolisat kolagen ikan gabus P3 (140 mg/200 g BB tikus) berpengaruh terhadap pengurangan kerusakan sel di area arteri pulmonalis jantung tikus wistar dan terjadinya dilatasi endotel jantung tikus wistar hingga sebesar 26 μm.   The potential biological activity of collagen can be enhanced through enzymatic hydrolysis. Therefore, this study conducted in vivo testing of snakehead fish (Channa striata) skin collagen hydrolysate on male Wistar rats and subsequently analyzed nitric oxide (NO) levels in the animal models. The aim of the study was to assess the potential and impact of different dosage levels of snakehead fish skin collagen hydrolysate as an antihypertensive agent on blood pressure and NO levels in hypertensive male Wistar rats induced with NaCl + Prednisone. The research used a completely randomized design (CRD) with 24 samples divided into six treatment groups: Normal Group (N), Positive Control Group (K+), Negative Control Group (K-), and Treatment Groups with different dosage levels of snakehead fish skin collagen hydrolysate (P1, P2, P3). The study consisted of two stages: stage 1 involved the production and identification of snakehead fish skin collagen hydrolysate, while stage 2 involved in vivo testing of the hydrolysate on animal models. In stage 1, the collagen hydrolysate was characterized using 1% bromelain enzyme, resulting in a yield of 12%, protein content of 49.2 mg/L, degree of hydrolysis 40.63%, a molecular weight range of 15–180 kDa, and profiles of 17 amino acid. In stage 2, blood pressure measurements showed an increase in the animal model induced with 2% NaCl + 1.5 mg/kg BW Prednisone, which decreased with different treatments in each group. The results of stage 2 showed that the highest NO level was found in the K+ group (134.81 μmol/L), while the lowest NO level was observed in the K- group (38.67 μmol/L). Administration of snakehead fish collagen hydrolysate P3 (140 mg/200 g BW rats) significantly reduced cellular damage in the pulmonary artery area of the heart and caused endothelial dilation in the heart of Wistar rats, reaching 26 μm.

Abstract

α-amylase has a pivotal role in catalyzing the cleavage of α-1,4-glycosidic bonds of polysaccharides to produce oligosaccharides. The inhibition of α-amylase delays the breakdown of carbohydrates, causing a reduction of blood glucose levels absorption in diabetes patients. The exploration of α-amylase inhibitors has attracted because society assumed that utilizing herbal medicine reduced the side effect of prescribed drugs. Mangrove from genus Ceriops have been used as antidiabetic, but the mechanism as α-amylase inhibitors has not been reported. Consumption of leaves extract of C.decandra reduced blood glucose level in diabetic rats, and triterpenoids have been identified from the leaves. With this in mind, this study aims to predict the molecular interactions between α-amylase (PDB ID: 4GQR) and the inhibitors, triterpenoid identified in C.decandra leaves, and to evaluate the potency of triterpenoid as α-amylase inhibitor. There are five triterpenoids identified in C.decandra leaves used as ligand tests, including lupenone, betulin, betulonic acid, betulinic acid, and lupeol. The descriptive method was applied in this investigation. This study was carried out from June to September 2022. Based on the molecular interactions, the binding affinity of triterpenoids was lower than the native ligand and control ligand. Lupenone, lupeol, betalonic acid, and betulinic acid inhibited α-amylase activity by non-competitive inhibition. It was predicted that betulin inhibited α-amylase activity through competitive inhibition.

Abstract

Ikan tuna merupakan komoditas laut unggulan dengan kandungan protein tinggi. Salah satu bentuk diversifikasi olahan yang potensial adalah sate lilit. Saat ini, proses pematangan sate umumnya menggunakan metode tradisional seperti pembakaran arang, yang kurang higienis dan efisien. Oleh karena itu, diperlukan metode alternatif seperti pemanasan menggunakan gelombang elektromagnetik (microwave). Penelitian ini bertujuan untuk mengevaluasi pengaruh metode pemanasan (tradisional dan microwave) serta variasi waktu pemanasan (8, 10, dan 12 menit) terhadap karakteristik organoleptik sate lilit ikan tuna. Penelitian dilakukan secara eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan pola faktorial 2 × 3, mencakup dua faktor: metode pemanasan dan lama waktu pemanasan, masing-masing diulang tiga kali. Parameter yang diamati meliputi warna, aroma, rasa, dan tekstur, dinilai secara organoleptik oleh 30 panelis tidak terlatih menggunakan uji hedonik skala 5. Hasil analisis menunjukkan bahwa metode pemanasan dan lama pemanasan berpengaruh signifikan terhadap seluruh atribut organoleptik. Perlakuan terbaik diperoleh pada pemanasan microwave selama 10 menit, menghasilkan warna kuning kecokelatan menarik, aroma tuna yang kuat, rasa gurih seimbang, dan tekstur padat namun tidak kering. Hasil ini menunjukkan bahwa penggunaan microwave selama 10 menit merupakan metode yang efektif untuk menghasilkan sate lilit tuna berkualitas, serta dapat dijadikan acuan dalam pengembangan produk olahan ikan dengan teknologi pemanasan yang higienis dan efisien.   Tuna is a leading marine commodity known for its high protein content. One potential form of product diversification is sate lilit (minced fish satay). Currently, the cooking process for this product commonly uses traditional methods such as charcoal grilling, which tend to be less hygienic and inefficient. Therefore, an alternative method is needed, such as electromagnetic heating using a microwave. This study aims to evaluate the effects of heating methods (traditional and microwave) and different heating durations (8, 10, and 12 minutes) on the organoleptic characteristics of sate lilit made from tuna.cThe research was conducted experimentally using a Completely Randomized Design (CRD) with a 2 × 3 factorial pattern, consisting of two factors: heating method and heating duration, each replicated three times. The parameters observed included color, aroma, taste, and texture, which were evaluated organoleptically by 30 untrained panelists using a 5-point hedonic scale. Statistical analysis showed that both heating method and duration had a significant effect on all organoleptic parameters. The best treatment was microwave heating for 10 minutes, which resulted in an appealing golden-brown color, a strong tuna aroma, a balanced savory taste, and a firm yet moist texture. These findings indicate that microwave heating for 10 minutes is an effective method for producing high-quality tuna sate lilit and can serve as a reference for further development in fish-based product diversification using appropriate and hygienic heating technology.

Abstract

Satay or satay is a food that is very popular with everyone and is quite popular in Indonesia, Malaysia and Singapore. Satay can be made from beef, chicken, lamb, and seafood such as tuna and shellfish. So far, octopus in the South Malang coastal area is also found in abundance during the season and is only sold in the form of fresh octopus. UMKM Mina Jaya Mandiri intends to serve processed octopus in the form of satay, so it is collaborating with the Malang Regency Fisheries and Maritime Service and Brawijaya University universities to get training on the diversification of processed octopus, in this case octopus satay. This community service program aims to (1) provide a general overview of the processing of octopus satay (2) train fish processors at Kondang Merak Beach MSMEs to make octopus satay products using a semi-mechanical grill. This community service activity was carried out by simulating the processing of octopus satay using a semi-mechanical grill. The results of community service activities at UMKM Mina Jaya Mandiri, Kondang Merak Beach show that MSME business actors are enthusiastic about making octopus satay in their respective places of business. The application of a semi-mechanical grill in making octopus satay provides a taste that is more popular with the public and is more efficient in terms of grilling time. This can encourage MSMEs to process fresh octopus into octopus satay using mechanical grilling technology and increase business actors' income from the increasing number of tourists visiting and enjoying various seafood culinary preparations at Kondang Merak Beach.
