Judul: Penentuan Kondisi Optimum untuk Mempertahankan Mutu Bekatul melalui Penghambatan Aktivitas Lipase oleh Protease Komersial
Abstrak: Rice bran is a by-product of milling process that contains protein and high essential components i.e. lysine, antioxidant, fiber, mineral and vitamin E. It makes rice bran have high potential for substitute material of foodstuffs. The use of rice bran as food and feed is limited, however, by its instability caused by hydrolytic and oxidative rancidity. Immediately following the milling process, rapid deterioration of the crude fat in the bran by lipase and, to a lesser extent, oxidase occurs and makes the bran unfit for human consumption. The naturally occurring lipase enzyme in the ric" bran hydrolyzes triglycerols, which are primary lipids.

Judul: Stabilisasi Tepung Bekatul dengan Metode Pemanasan Bertekanan dan Pengeringan Rak serta Pendugaan Umur Simpannya.
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: Desain Taman Patung di Taman Monas, Jakarta Pusat.
Abstrak: Penyajian patung-patung menggunakan berbagai elemen desain secara fisik, dengan menggabungkan antara seni dan lanskap. Salah satu elemen tersebut dapat berupa Taman Kota yang juga berfungsi sebagai sarana sosial dan rekreasi bagi masyarakat. Taman Monas merupakan salah satu Taman Kota yang menampilkan berbagai patung di sekitar lanskapnya. Kondisi saat ini, menunjukan kondisi yang buruk pada patung-patung yang disajikan, hal ini selaras dengan buruknya apresiasi masyarakat terhadap patung-patung tersebut. Oleh karena itu, penelitian ini bertujuan untuk mengidentifikasi dan menganalisis keberadaan dan aktifitas di Taman Monas, menyusun konsep, dan merancang Taman Patung pada Taman Monas. Selain itu, penelitian ini menggunakan metode deskripsi secara kuantitatif dan kualitatif. Metode yang dilakukan, menghasilkan konsep dasar berupa era kependudukan Jepang yang terjadi pada tahun 1942 sampai tahun 1945, dengan konsep desain berupa “bambu runcing”. Penelitian ini menghasilkan siteplan yang dilengkapi dengan ilustrasi 3D yang diperjelas dengan gambar detil. Penelitian ini diharapkan dapat meningkatkan kemampuan mahasiswa dalam bidang Arsitektur Lanskap, menjadi bahan masukan bagi pengelola Taman Monas sebagai area display patung, serta sebagai bahan referensi Taman Patung bagi kota-kota lain di Indonesia.
