Judul: Beberapa Aspek Biologi Ikan Selar Kuning (Selaroides leptolepis Cuvier, 1833) di Selat Sunda
Abstrak: Ikan selar kuning (Selaroides leptolepis) merupakan salah satu ikan pelagis kecil dari famili Carangidae yang memiliki bentuk tubuh pipih dan memanjang. Tujuan penelitian untuk menganalisis beberapa aspek biologi ikan selar kuning (Selaroides leptolepis) di Selat Sunda. Penelitian ini dilaksanakan pada bulan Mei-September 2018 di Selat Sunda. Metode yang digunakan dalam penelitian ini adalah penarikan contoh acak sederhana (PCAS) dengan jumlah contoh 465 ekor ikan. Hasil analisis rasio kelamin antara ikan jantan dan betina adalah seimbang (1:1,17). Ikan selar kuning tumbuh secara alometrik negatif dengan dugaan ukuran pertama kali matang gonad pada ukuran 134,17 mm dan 121,98 mm untuk ikan jantan dan betina. Ikan selar kuning melakukan pemijahan sekitar bulan Agustus-September dengan pola pemijahan total spawner dan jumlah telur berkisar antara 1429-9391 butir.

Judul: Aspek Biologi Reproduksi Ikan Selar Kuning (Selaroides leptolepis Cuvier, 1833) Di Perairan Selat Sunda, Provinsi Banten
Abstrak: Sumber daya ikan pelagis kecil yang didaratkan di PPP Labuan, Banten salah satunya adalah ikan selar kuning (Selaroides leptolepis). Ikan selar kuning memiliki nilai ekonomis penting di Selat Sunda dengan permintaan pasar terhadap ikan selar kuning yang cukup tinggi. Tujuan dari penelitian ini untuk mengkaji aspek reproduksi ikan selar kuning (Selaroides leptolepis) dari perairan Teluk Banten yang di daratkan di PPP Labuan, Banten. Data yang digunakan adalah panjang dan bobot ikan, jenis kelamin ikan, tingkat kematangan gonad (TKG), bobot dan volume gonad, jumlah telur, dan diameter telur. Ikan selar kuning memliki pola pertumbufian allometrik negatif. Hasil nisbah kelamin ikan selar kuning dalam keadaan tidak seimbang dengan jumlah ikan selar kuning betina sebesar 221 ekor dan jumlah ikan selar kuning jantan sebesar 274 ekor. Untuk ikan selar kuning betina nilai faktor kondisi terendah dan tertinggi yaitu sebesar 0,9155 dan 1,0804 sedangkan untuk nilai faktor kondisi ikan selar kuning jantan yaitu sebesar 0,8689 dan 1,0781…

Judul: Development of Potentially Functional Drink from Skimmed Milk Enriched with Red or Black Variety Rice Bran
Abstrak: Rice bran is a good source of antioxidants such as polyphenol compounds that are potentially formulated in skimmed milk drink. The objectives of this research were to develop potentially functional drink from skimmed milk enriched with red or black variety rice bran and to evaluate their physical, chemical and sensory qualities. The milk drinks were formulated with skimmed milk (95%) and sucrose (5%) as fixed formula. Considering the result of preliminary research, the addition of red or black variety rice bran at amount of 4, 6, 8% (w/w) and carboxy methyl cellulose (CMC) at amount of 0, 0.05, 0.1% (w/w) were based on fixed formula and water addition in ratio 4:1 (w/w) of water weight and total weight of skimmed milk powder, sucrose, rice bran, and CMC. The milk drink formula was selected based on total phenolic content (TPC), total anthocyanin content (TAC) and its antioxidant activities using DPPH and FRAP assay. Two selected formulas were characterized in terms of physical properties (viscosity and colour), chemical properties (pH, total soluble solid, and proximate), and sensory evaluation by rating hedonic. Red and black variety rice bran had high TPC with amount 512.19±43.91 and 1247.56±196.34 mg GAE/100 g, TAC with amount 1.94±0.19 and 40.69±4.21 mg C-3-G/100 g, respectively. Red and black variety rice bran also showed antioxidant activity based on DPPH assay (106.68±13.49 and 209.93±19.75 mmol Trolox/100 g, respectively) and FRAP assay (8.04±0.39 and 14.66±0.56 mmol FeSO4/100 g, respectively). The milk drink enriched with red variety rice bran, the highest content of TPC (33.83±1.00 mg GAE/100 mL), TAC (1.86±0.32 mg C-3-G/L), and antioxidant activities of DPPH (83.38±1.37 mmol Trolox/100 mL) and FRAP (0.43±0.01 mmol FeSO4/100 mL) by addition of 8% red variety rice bran and 0.05% CMC. The milk drink enriched with 8% black variety rice bran and 0.1% CMC showed the highest values in TPC (39.61±0.11 mg GAE/100 mL), DPPH (196.22±3.77 mmol Trolox/100 mL), FRAP (0.63±0.07 mmol FeSO4/ 100 mL) and TAC (5.53±0.03 mg C-3-G/L). Furthermore, the proximate analysis showed that the selected drinks had low fat content and high fiber content. Both milk drinks also were moderately liked on overall liking attribute. Based on its TPC, TAC and antioxidant activities, these milk drinks enriched with black and red variety rice bran are potentially developed as functional drinks.
