Judul: Keanekaragaman Jenis Kelelawar di Desa Cikarawang Kecamatan Dramaga Kabupaten Bogor Provinsi Jawa Barat
Abstrak: Bat is one type of mammals having an important role for human life. The role consist of plants pollinators agent, plant seed disperser, producing guano for fertilizer, and as controlling pests insect of plants. This study aims to identify the bats species and measuring bats community similarity between paddy fields, garden, and forest habitat. The amount of the successful caught during this studies about 11 species of four family, namely: Hipposideridae (1 species), Vespertilionidae (4 species), Rhinolophidae (1 species), and Pteropodidae (5 species). Diversity index of bats in garden habitat is 1.80, forest habitat is 1.64, and paddy field habitat is 1.29 respectivelly. Similarity of bats community betwee garden and paddy field habitat is 0.72, between forest and garden habitat is 0.46, and between forest and paddy field is 0.36 respectivelly.

Judul: Keanekaragaman Jenis Kelelawar di Hutan Penelitian Haurbentes-Jasinga, Kabupaten Bogor, Jawa Barat
Abstrak: Kelelawar memiliki peran penting terhadap ekologi. Kerusakan habitat diduga berdampak negatif terhadap keanekaragaman jenis kelelawar sehingga mengakibatkan ketidakseimbangan ekosistem alami. Penelitian bertujuan mengukur tingkat keanekaragaman jenis kelelawar dan mengukur parameter lingkungan yang berpengaruh terhadap keanekaragaman jenis kelelawar. Pemerangkapan dengan jala kabut di empat lokasi yaitu tegakan Dipterocarpaceae, sawah, kebun karet, dan agroforestry. Sebanyak 11 jenis kelelawar tertangkap selama penelitian terdiri dari famili Pteropodidae 8 jenis, Vespertilionidae 2 jenis, Rhinolophidae 1 jenis. Kepadatan jenis tertinggi yaitu Cynopterus brachyotis 0.109 individu/m2 malam-perangkap. Tegakan Dipterocarpaceae memiliki kekayaan dan keanekaragaman jenis tertinggi H’=2.12, Dmg=4.83. Kesamaan komunitas kelelawar tertinggi terjadi antara sawah dengan agroforestry yakni 0.80. Kerapatan tiang berpengaruh terhadap jumlah jenis yang ditemukan Y=3.933–2.16x (R2=0.30) sedangkan kerapatan pohon berpengaruh terhadap kehadiran jenis C. brachyotis Y=0.867-0.701x (R2=0.29) dan Rhinolopus luctus Y=0.133+0.276x (R2=0.29).

Judul: Characteristic of chili drying (Capsicum annum L.) as a natural dyeing cosmetic
Abstrak: Chilli (Capsicum sp.) contains carotenoids, which are a group of natural pigments consist of red, orange or yellow color. Carotenoids can be dissolved in lipid so that they can be applied to oil-based cosmetic ingredients. Therefore, chilli is potential to be developed as cosmetic colorants. However, pungency of red chili needs to be removed because it is irritating and it provides stinging sensation to skin. Red chilli was investigated as a potent material for a cosmetic colourant in this research because it has a nice uniform red color and has a pungency level less than cayenne pepper. The purpose of this research was to investigate the influence of blanching on drying characteristics of red chilli using a tray dryer, determine the proper time of chili blanching in sodium bisulfite solution, examine color changes stability of red chili powder as a cosmetic dye, and analyze the effect of oleoresin extraction on color and pungency level of red chili powder. The results showed that blanching could affect the drying characteristics. Blanching the chilli for 9 minutes prior drying could speed up the drying rate of chilli and thus the drying time, therefore, the chilli achieved the desired moisture content fast. Sodium bisulfite solution of 0.2%, used as the blanching media, could maintain the color well. However, longer time of blanching might cause several pigments soluble in the blanching media. Blanching the chilli for 9 minutes was able to maintain red color after the stability tested and after extraction of oleoresin. Therefore, blanching red chilli in a solution of 0.2% sodium bisulfite for 9 minutes prior drying is concluded as the best treatment to retain the color of red chilli powder
