Abstrak: Microencapsulation is a process for covering a component or a mixture of components with the other materials. The objective of this research is to study the emulsification and drying process of red palm oil emulsion to produce microencapsulated product with efficient production process. In this research, the coating materials used to form the emulsion of red palm oil are maltodextrine, gelatine, and carboxymethylcellulose (CMC). The good emulsification process can be achieved by homogenization of coating materials in 8 minutes and emulsion homogenization in 27 minutes, with the highest emulsion stability with the smallest creaming index (2.58%) and the smallest fat globule (20-60 μm). Tray dryer needed 25 minutes for preheating. The racks that can be used in the drying process are rack 2, 3, 4, and 5. The drying process must be conducted until the product has moisture content in 2 %db (dry basis). The position of the racks and the thickness of the emusion affected the drying time, the moisture content and the drying rate. The analyzed results showed that the drying time to achieve moisture content 2 %db in the thickness of emulsion 0.5, 1.0, 1.5 and 2.0 mm respectively are ± 3.57, ± 5.56, ± 7.30, and ± 11.40 hours. Based on these data, we can conclude that the thickness of the emulsion will lengthen the drying time and decrease the drying rate to achieve the same moisture content. Total weight that gained in the thickness of emulsion 0.5, 1.0, 1.5 and 2.0 mm respectively are 72.42, 143.21, 266.65 and 343.79 g, while the yields obtained respectively are 22.61, 22.37, 28.67 and 28.13%. The recommendations thickness which produces the good drying process parameters was 1.5 mm.

Judul: Kajian Produksi Mikroenkapsulat Minyak Sawit Merah dengan Pengering Semprot Skala Pilot Plant (300mL/Menit)
Abstrak: Minyak sawit merah mengandung total karoten yang tinggi yang dapat digunakan sebagai pewarna dan sumber provitamin A. Upaya untuk mempertahankan kandungan provitamin A adalah dengan proses mikroenkapsulasi dengan spray drying atau pengering semprot. Penelitian ini bertujuan untuk melakukan kajian produksi mikroenkapsulat minyak sawit merah dengan pengering semprot skala pilot plant (300mL/menit). Proses pembuatan mikroenkapsulat minyak sawit merah (MMSM) dilakukan dengan melakukan formulasi menggunakan pengering semprot skala laboratorium Buchi 190 mini spray dryer menghasilkan formula terbaik dengan perbandingan (Maltodekstrin:Gum Arab) : Minyak sawit merah = (35:15) : 40 atau 1 bagian penyalut terhadap 0,8 bagian minyak sawit merah. Peningkatan skala dilakukan dengan menggunakan pengering semprot skala pilot plant. Hasil menunjukan formula terbaik dengan pengering semprot skala laboratorium harus disesuaikan kembali untuk memproduksi MMSM dengan pengering semprot skala pilot plant. Ukuran droplet yang dipengaruhi oleh laju alir produk dan jenis atomizer menjadi faktor penentu keberhasilan dalam memproduksi MMSM ini. Penyesuaian formulasi dilakukan dengan merubah komposisi formulasi. Pada parameter suhu inlet 215oC, suhu outlet 110oC, tekanan pompa 4.5 bar, kecepatan cyclon 2500 m 3 /jam dan laju alir 300 mL/menit, dapat diproduksi MMSM pada range perbandingan penyalut dan MSM adalah 1:0.3 hingga 1:0.6.

Judul: Etno-ornitologi Burung Kancilan Flores (Pachycephala nudigula nudigula Hartert 1897) pada Masyarakat Lio di Taman Nasional Kelimutu
Abstrak: Bare-throathed whistler is one of several wild birds in Kelimutu National Park (TNKL) that is believed to have correlation with Lio Community‟s belief. The estimation of Bare-throated whistler‟s population in Kelimutu National Park was about 186.41-1668.07 individual by the density about 0.0389-0.3481 ind/ha with the sex ratio 6.2:1 that spreaded on area with height of 1100 – 1600 masl. The characteristic of Bare-throated whistler‟s habitat is a natural forest with various canopy level, high plant species diversity and high density. The habitat characteristics related to the availability of food in the form of insects, cover, safety and a nesting site. Generally the most of Lio community knew the existence of Bare-throated whistler directly or from their parents‟ stories. The perceptions of Lio Community to the Bare-throated whistler‟s existence is generally support the conservation efforts. The perceptions construct the Lio Community‟s atitude that tend to be conservative to the existence of Bare-throated whistler. The attitude shown by their behavior that not cathing the Bare-throated whistler from the TNKL‟s area or the outside. The attitude have an important role to the existence of Bare-throated whistler in Kelimutu National Park‟s area.
