Judul: Rice Bran Stabilization and y-Orizanol Content of two Local Paddy Varieties "IR 64" and "Cisadane Muncul"
Abstrak: An auioclaving procedure was developed to produce stable rice bran frcvn two local paddy varieties IR 64 and Cisadane Muncul. The stable rice bran showed no significant increase in free fetty acid content for 144 hours at 37OC. In the optimum wet heating process, rice bran was heated at 121 4: and held for 3 minutes before cooling for both varieties. Stable rice bran contained 3.8 % moisture and the content of tofd tocophem1 was nd much changed by heating process, i.e., 209.8 mg'100 g rice bran oil and 279.8 for control (without heating process) of IR 64 vanety and 227.4 mg'100 g rice bm oil and 248.8 for control of Cisedane Muncul variety, mpect~ely.T he content of y-oryzanol van'ed and was depended on the degree of milling ranged from 39.1 to 147.7 mg'100 g rice bran oil for both of IR 64 and Cisadane Muncul rice varieties. The content of soluble dietery h r varied md was depended on the degree of milling which ranged from 3.56 to 8.76 % for both of IR 64 and Cisadane Muncul rice van'eties. The content of insduble detery tiber van'ed and was depended on the degree of millng which ranged horn 15.00 to 25.38 % for both of IR 64 and Cisadme Muncul rice v8riefies.

Abstrak: The national production of the unhulled rice on 2007 reported about 60,3 million tons (BPS,2008). The by product is about 12,1 million tons hull, 1,8 million tons broken rice, and 6 million tons bran. For this time bran is used as feed for breed animals and as medium to grow fungi, even though the bran is a potential source of phytochemical materials. The bran contain some of vitamin, minerals, and other nutrition that is necessary to keep human health. The problem is the bran contain many enzymes, especially lipase that can trigger rancidity process in the bran if they don’t be handled well. One of the tech to solve this problem is using pressed steaming. The purpose of this research is to obtain characteristic of the fresh bran, the time of stabilization with pressed steaming and predict storage time of stabilized bran. The fresh bran characteristics include the water level 11,30 %, protein 14,41 %db, fat 18,99 %db, crude fibre 7,25 %db, carbohydrate 46,06 %db, ash 7,8%db, and TBA 1,36 mg malanoldehid/kg of sample. The fresh bran then stabilized by using pressure of heating method (autoclave). Time of process that is used are 5, 10, 15 minutes and dried during 4 hours. Stabilized bran with heating process at 5 minutes was decided as material for predicting of storage time with characteristic of water level 4.94 % and TBA value 0.11 mg malanoldehid/kg of sample. The low of water level can inhibit destruction of the bran and the low of TBA value showed the little action of destruction of the bran. During the storage, the water level and the brightness of the bran has been decreased, mean while TBA value has increased as same as the storage time. The bran is packed by using metallized material and be storaged in the incubator at 35oC, 45oC, and 50oC during 8 weeks. The critical point of this analysis is based on the TBA value. TBA value is opted as the critical point because of can be used as indicator of the succeed factor of stabilization, that showed rancidity indicator. Critical point of TBA value is based on odor test, the value is 0,36 malanoldehid/kg of sample. The Arrhenius equation for the storage is k = 25,1033 e-2092/T. The storage time of the bran at temperature storage 15°C is 9 weeks, 25°C is 7 weeks, and 30°C is 6 weeks 2 days.

Judul: Organisasi kerja dalam penyelenggaraan taman
Abstrak: Manusia (Homo sapiens) seperti halnya makhluk hidup yang lainnya membutuhkan tempat yang ideal untuk kelangsungan hidupnya. Dan untuk itu bukan saja materi yang dibutuhkan, akan tetapi kebutuhan rohani sudah selayaknya pula dipenuhi. Taman adalah suatu susunan massa di dalam suatu susunan ruang terbuka, untuk melengkapi lingkungan hidup agar diperoleh lingkungan hidup yang ideal. Pada kebanyakkan orang ada pendapat bahwa taman adalah suatu kebutuhan rohani yang terlalu mahal, lebih-lebih di kota-kota besar dimana sebagian penduduknya tidak mempunyai halaman rumah untuk dijadikan taman. Padahal tidaklah selalu demikian. Susunan dari pot bunga-bungaaan yang tersusun indah pada dinding rumah dapat merupakan sebuah taman yang sederhana yang membutuhkan ruang relatif sempit. Untuk taman-taman yang membutuhkan ruang relatif sempit atau taman-taman dalam sekala kecil, acapkali si pemakai sekaligus bertindak sebagai perancang dan pelaksana. Akan tetapi tidak begitu halnya pada taman-taman yang bersekala besar, baik itu berupa taman rumah tinggal yang berhalaman luas ataupun pada tingkat yang lebih besar lagi seperti Taman Mini Indonesia Indah dan Taman Nasional. Pada taman yang demikian itu jumlah manusia yang terlibat di dalam penyelenggaraannya lebih banyak. Bahkan mereka dapat berasal dari instansi-instansi yang berbeda yang bekerja sama sehingga terciptalah taman yang sesuai dengan keinginan si pemakai.
