Aruk rice is an iconic rice from Province of Bangka Belitung which is made from cassava while purple aruk rice (PAR)e is made from sweet potato (Ipomea batatas). Ipomea batatas is a high nutritional food that possesses several medicinal value including anti-cancer, antidiabetic, and anti-inflammatory activities. This research aimed to assest the organoleptic features of PAR and analyze the effect of PAR consumption in lowering the BMI and bofódy fat percentage. The design of this research was randomized crossover design with quasi experimental research within subjects single-factor two-level design. This experiment consist of three phases, phase 1 (plain rice consumption), wash out phase, and phase 3 (PAR consumption). The only different between two phases was the source of the carbohydrate. The data of decreasing BMI and body fat percentage betweern plain rice diet and purple aruk rice was analyzed by using paired t test. Organoleptic assessment showed that the aroma of PAR is dislikeable but the natural purple colour is likeable. The decreasing of BMI and body fat percentage was found higher in phase 2 (2,05±0,10) than phase 1 (0,4±0,14), p=0,002. The decreasing of body fat percentage was also found higher in phase 2 or purple aruk rice diet (2,55±0,25) compared to phase 1 plain rice diet (0,5±0,20), p=0,003. Consumption of aruk purple rice lower BMI and body fat percentage more effective than consumption of plain rice.

The examination of the acoustic characteristic of rice bran has been performed. The materials are the alternative materials of the noise controllerfrom the use of synthetic fiber materials like glasswool. The examination is completed by using tube impedance method. The result of the examination reveals that the natural fiber materials that have been mixed with glue have a good value of sound absorption at frequency 400-1200 Hz whereas at frequency 200 Hz, its value does not change significantly. The high value of the sound absorption is owned by materials with the bigger porous. Beside the coefficient of the absorbtion, the examination of value of acoustic impendence is also performed. The result shows that the similar composition between natural fiber and glue has a bigger value of impendence compared to the lower composition of glue. It is caused by the fulfillment of the bigger amount of the porous by glue.

STUDY OF HUMAN ANCESTORS NUSA TENGGARA TIMUR INDONESIA BASED ON Y CHROMOSOME.
Genetic studies conducted in NTT region focused on four islands namely Flores, Sumba, Alor, and Timor. The islands of NTT are a transition zone between Papuan and Austronesian speakers. Genetically there is also an intensive mixing. The dominant genetic of tribes in Alor island is Papua / Melanesia, but on the other islands there is almost uniform mixing. In the western part of Sumba Island there is a majority area of the Papuan/ Melanesian genetic type, while the tribes in eastern Sumba, Sabu and Rote are Austronesian. Genetic mixing is also seen on Timor Island. West Timor is the more dominantly Austronesian type, while central and eastern Timor are a mixture of Papua/ Melanesia with Austronesian. On such Flores islands, the tribes in the eastern and central regions have the Papua/ Melanesian type, while the western part is almost entirely of Austronesian type. The tribes on Solor, Lembata and Adonara Islands also have mixed types between Austronesia and Papua/ Melanesia. Based on paternal lineage, the blood flowing in NTT people consists of seven line ages of East Asia, Taiwan, Southeast Asia, Arab, Japan, Europe and Papua/ Melanesia, characterized by the detection of thirty-two Y-DNA markers: C-M130/ RPS4Y, F-P14/F-M89 (East Asia), NO-M214, O-M175, O-M119, O-M95, O-P203, O-M110, O-M122, O-M134, O-P201, O-JST3002611 (Taiwan), K-M526, K-P397, K-P405, K-P79, K-P336, P-P295, Q-M242, Q-P36 (Southeast Asia), J-M172 (Arab), C-P343, D-M116 (Japan), E-P1 (Europe),C-M38, C-M208, C-P355, M-P256, M-M4, M-P34, S-M230, S-M254, S-P377 (Melanesia).
Studi genetik yang dilakukan di daerah NTT difokuskan pada empat pulau yakni Flores, Sumba, Alor, dan Timor. Pulau-pulau di NTT menjadi zona transisi antara penutur Papua dan Austronesia. Secara genetika juga terjadi pembauran yang intensif. Suku di pulau Alor, genetiknya dominan Papua/ Melanesia, namun di pulau-pulau lain terjadi pembauran hampir merata. Di Pulau Sumba bagian barat ada kawasan yang genetikanya mayoritas bertipe Papua/ Melanesia, sedangkan suku di Sumba bagian timur, Sabu dan Rote bertipe Austronesia. Pembauran genetika juga terlihat di Pulau Timor. Timor barat lebih dominan bertipe Austronesia sedangkan Timor bagian tengah dan timur merupakan campuran Papua/ Melanesia dengan Austronesia. Di pulau florespun demikian, yakni suku-suku di bagian timur dan tengah memiliki tipe Papua/ Melanesia, sedangkan bagian barat hampir seluruhnya memiliki tipe Austronesia. Suku-suku di pulau Solor, Lembata dan Adonara juga memiliki tipe campuran antara Austronesia dan Papua/ Melanesia. Berdasarkan garis keturunan ayah, darah yang mengalir dalam orang NTT terdiri atas tujuh garis keturunan yaitu Asia Timur, Taiwan, Asia Tenggara, Arab, Jepang, Eropa dan Papua/ Melanesia, yang ditandai dengan terdeteksinya tiga puluh tiga penanda Y-DNA yakni: C-M130/ RPS4Y, F-P14/F-M89 (Asia Timur), NO-M214, O-M175, O-M119, O-M95, O-P203, O-M110, O-M122, O-M134, O-P201, O-JST3002611 (Taiwan), K-M526, K-P397, K-P405, K-P79, K-P336, P-P295, Q-M242, Q-P36 (Asa Tenggara), J-M172 (Arab), C-P343, D-M116 (Jepang), E-P1 (Eropa),C-M38, C-M208, C-P355, M-P256, M-M4, M-P34, S-M230, S-M254, S-P377.
