Judul: Analisis populasi penyu hijau (Chelonia Myas, Lennaeus 1758) di pantai Pangumbahan, Kabupaten Sukabumi
Abstrak: Penelitian ini dilakukan di Pangumbahan, Kabupaten Sukabumi, selama 46 hari dari bulan Mei sampai dengan Juli 2006. Tujuan penelitian ini adalah untuk mendeskripsikan sebaran populasi penyu hijau berdasarkan ukuran panjang karapas lurusnya (SCL). Penyu Hijau yang diamati memiliki ciri warna karapas cokIat karat kemerah-merahan dengan coreng kuning gading. Bagian kepala kemerahmerahan dengan tepi hitam. Sisi kepala yang lain berwana gelap dengan garis pertemuan antar sisik (sutures) berwarna kuning. Penyu muda berwarna hijau pudar sampai coklat gelap bercoreng kuning dengan bagian sirip berwarna gelap. Cjri-ciri tersebut merupakan ciri dari jenis Chelonia mydas dan lebih mendekati pada subspecies C. mydas japonica yang biasa terdapat di wilayah Pasifk Barat dan Samudera Hindia.

Judul: Status Populasi Penyu Hijau (Chelonia mydas, Linnaeus 1758) di Taman Pesisir Pantai Penyu Pangumbahan, Kabupaten Sukabumi, Jawa Barat.
Abstrak: The populations of green turtles in Indonesia tend to decline in linearly over the time that affects the sustainability of green turtle. The turtles beach of Pangumbahan consist of productive area for green turtles landing and nesting habitat. Research to assess the status of sea turtle population from the past few years was carried out using data from management and from field survey on the coast of Pangumbahan beach in March until April 2014. The purpose of this research is to study green turtles population change and the production of eggs from 2007-2013, and to assess threat to green turtles (biophysical properties of habitat, number of tourist, villas and the number of building), and to recommends management strategy for green turtles conservation. Social data was taken using purposive sampling methods and length of green turtles was taken using curve carapace line method. The frequency of green turtle landing in 2009 to 2013 is dominated un nested. There is a declining trend of number of green turtles that nest in 2007-2013. This has an impact to production of eggs and hatchlings which showed a decline. A decrease in the frequency of green turtles that landed in the beach might be caused by variation of nesting activity, the number of eggs, and hatching success. Another threat to the population of nesting green turtles changes in turtles habitat at Pangumbahan beach, the level of lighting of the beach, the increasing number of buildings villa, and social condition.

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.
