Abstract

Teh hijau telah lama dikenal sebagai minuman yang memiliki berbagai manfaat kesehatan, terutama karena kandungan antioksidannya yang tinggi. Daun mangrove berpotensi sebagai bahan baku teh hijau karena memiliki senyawa metabolit sekunder yang bersifat sebagai antioksidan. Penelitian ini bertujuan untuk menentukan spesies mangrove terbaik yang berpotensi sebagai teh hijau melalui parameter kimia, antioksidan, dan penilaian hedonik. Teh hijau diproduksi dari daun muda bagian pucuk mangrove Avicennia sp. dan Sonneratia sp. yang diperoleh dari kawasan ekosistem Bandar Bakau, Kota Dumai dan teh komersial (Camellia sinensis) sebagai pembanding. Parameter yang dianalisis meliputi karakteristik kimia (kadar air, abu, abu tak larut asam, sari larut air, dan serat), fitokimia, persentase inhibisi antioksidan metode DPPH, serta penilaian hedonik (rasa, aroma, warna, dan overall). Hasil penelitian menunjukkan ketiga jenis teh memiliki kadar air 7,84-25,45%, abu 6,69-16,12%, abu tak larut asam 0,65-1,23%, sari larut air 2,82-4,27%, dan serat 5,80-7,11%. Senyawa fitokimia lebih banyak terdeteksi pada teh komersial dibandingkan teh daun mangrove. Perbedaan jenis bahan baku teh hijau berpengaruh nyata terhadap persentase inhibisi antioksidan dan penilaian hedonik panelis. Perlakuan terbaik teh hijau dengan daun mangrove Sonneratia sp. dengan persentase inhibisi antioksidan tertinggi (87,59%) dan penilaian hedonik keseluruhan (overall) sangat disukai panelis. Teh ini memenuhi standar teh hijau sesuai SNI 3945:2016 pada kadar abu, abu larut asam, dan serat kasar, namun belum pada kadar air dan sari larut air. Hasil penelitian mengindikasikan daun mangrove berpotensi sebagai bahan baku teh hijau.

Abstract

Male tilapia fish grow faster than female tilapia, so administering synthetic steroids orally or by soaking has proven to be the simplest, easiest, most effective and reliable technology for sex reversal of tilapia larvae to become males. This research was conducted to analyze the administration of 17α- methyltestosterone on the growth rate and feed conversion of tilapia (O.niloticus). This study used a completely randomized design (CRD) consisting of 3 treatments and 4 replications. The optimum dose used is (60) mg/kg feed, and 0.5 ml/l. The results of this study showed that body weight gain with oral treatment had the best average, namely 226.83c ± 11.88; average length 12.79b ± 0.99, specific growth rate (SGR) 5.46c ± 0.06 and FCR namely 1.05a ± 0.06. Research on the effect of using 17α-methyltestosterone on the growth of oral male tilapia fish obtained the best results by not exceeding the residue limit (5 µg/L or 5 µg/kg) of synthetic steroids in the body of tilapia fish.

Abstract

Red snapper (Lutjanus sp.) is one of the most popular fish species because of its delicious taste with thick and dense meat and high nutritional content such as protein, omega 3 fatty acids, vitamins, and minerals known to be very productive for heart health, brain, bones, and endurance. Red snapper (Lutjanus sp.) as a fishery product is perishable and requires good handling to maintain the quality standards of the fish. Fish quality is an important requirement in the export process based on predetermined standards to prevent biological, chemical, and physical hazards. One of the fish quality testing processes carried out is microbiological testing by looking at the Total Plate Number (ALT) of bacteria. The calculation is carried out based on the SNI 2332:2015 (How to tet microbiology-part 3: Determination of total plate count). Testing was carried out in the laboratory of the Fish Quarantine Centre, Quality Control and Safety of Fishery Products (BKIPM) in Tarakan City. The results showed that the tested red snapper samples contained 3,3 x 103 colonies/g and were still below the maximum limit of 5x105 colonies/g. Red snapper (Lutjanus sp.) in Tarakan City is considered safe and suitable for export in accordance with SNI fresh fish quality requirements in SNI 2729: 2021 and SNI 7388:2009 on the maximum limit of microbial contamination in food.
