Judul: Keanekaragaman Repril di Sekitar Kawasan Suaka Margasatwa Nantu Provinsi Gorontalo
Abstrak: Sulawesi island is known for high endemicity of mammals, birds, amphibians and reptiles. Previous amphibians and reptilians survey showed that amphibians and reptiles diversity in this area are still negleted. This research was conducted on June 13th until 27th of Juni 2013 on the eastern part of Nantu Wildlife Reserveand around Bontula village. The objective of this study is to identify the composition of reptile and comparing reptile diversity based on habitats. This study resulted in 19 species reptiles consisting of 54 individual found on seven sampling sites. Three species were Sulawesi endemics consisting of Chrysopelea paradisi celebensis, Rhabdophis callistus, Cyrtodactylus jellesmae and 12 species were classified as Least Concern (LC) based on IUCN redlist.Undisturbed habitat has the highest index of Shannon Wiener diversity (2.11) whilst the lowest index is found on housing area (0.68). Changes in habitat conditions is predicted affect the microclimate of location which caused the majority of reptile unable adapt.

Judul: Diversity of Reptiles Based on Habitat Disturbance in Production Forest Areas in Boven Digoel Regency South Papua Province
Abstrak: Aktivitas manusia dapat menyebabkan penurunan kualitas habitat termasuk reptil. Penelitian ini bertujuan mendeskripsikan kondisi umum habitat, mengidentifikasi keanekaragaman, kekayaan, kemerataan, dan kesamaan komunitas reptil berdasarkan tipe gangguan habitat di kawasan hutan produksi Kabupaten Boven Digoel, Papua Selatan. Metode penelitian yang digunakan adalah Visual Encounter Survei (VES) dan jebakan lem (Glue Trap). Ditemukan 176 individu dari 5 famili dengan 18 jenis yang berbeda, namun kekayaan jenis tersebut masih berpotensi meningkat berdasarkan kurva akumulasi jenis dan indeks Schao. Keanekaragaman dan kekayaan jenis tertinggi berada di habitat kurang terganggu (H’= 1,113 dan Dmg= 2,495). Kemerataaan jenis di ketiga tipe gangguan habitat tergolong rendah (E= 0,249-0,485) karena terdapat spesies yang mendominasi yaitu Carlia aenigma. Komunitas reptil habitat belum terganggu bersifat unik karena berbeda dengan habitat yang lainnya., Human activities can cause a decrease in the quality of habitat, including reptiles. This research aims to describe the general condition of the habitat, identify the diversity, richness, evenness, and similarity of reptile communities based on the habitat disturbance in the Production Forest Area Boven Digoel Regency, South Papua. Visual Encounter Survey (VES) and glue trap (Glue Trap) are used as research methods. Obtained 176 individuals from 5 families with 18 different species. The richness of these species still has the potential to increase based on the species accumulation curve and the Schao index. The highest species diversity and richness were in less disturbed habitats (H'= 1,113 and Dmg= 2,495). The evenness of species in the three types of habitat disturbance is relatively low (E= 0,25-0,48) because there is a dominating species, Carlia aenigma. The undisturbed habitat of the reptile community is unique because it is different from other habitats.

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.
