Judul: Pengaruh Pemberian Kitosan dan Nanokitosan dari Cangkang Rajungan (Portunus pelagicus) terhadap Kadar Trigliserida Tikus Sprague-dawley
Abstrak: Hipertrigliseridemia adalah salah satu kelainan metabolisme lipid yang ditandai dengan peningkatan fraksi lipid dalam plasma. Kitosan mampu menyerap lemak sehingga mampu menurunkan kadar lipid. Tujuan penelitian ini adalah membandingkan pengaruh pemberian kitosan dan nanokitosan terhadap kadar trigliserida tikus Sprague-dawley. Penelitian ini dilakukan beberapa tahap, yaitu karakterisasi kitosan, pembuatan nanokitosan, serta uji in vivo kadar trigliserida. Hasil PSA yang dilakukan sebanyak 3 ulangan menghasilkan rata-rata distribusi ukuran partikel sebesar 234,09±31,25 nm. Viskositas intrinsik dan berat molekul kitosan berturut-turut yaitu 26,16±1,03 cP dan 2586,24±186,00 kDa, sedangkan nanokitosan yaitu 0,38±0,09 cP dan 9,84±3,17 kDa. Nanokitosan dosis 200 mg/kg bb/hari dapat menurunkan kadar trigliserida sebesar 63,33±32,58 mg/dL atau 50,94±48,79% dari 124,33±46,11 mg/dL menjadi 61,00±18,03 mg/dL…

Abstrak: This study was aimed to analyze chitosan intake on plasma triglyceride levels and body weight in rats Sprague-dawley fed by trans fatty acid. This study was experimental study with Post Test Only Control Group Design. The subjects were male Sprague-dawley rats, 2 months old. The subjects were divided in to 1 control (K) and 3 treatment groups which received chitosan as much as 0.035 g (P1), 0.045 g (P2), and 0.055 g (P3). Fed with high-fat diet was given by melted margarine as source of trans fatty acids as much as 1.7 g per day for 4 weeks. Measurement of triglyceride levels was done at second week dan fourth week after intervention and the body weight was weighed once per 3 days. The study revealed that feeding of margarine in a dose of 1.7 g per day increased body weight most high in K0 amount 32.1% or 63.8 g during 2 weeks and 54% or 107.2 g during 4 weeks intervention. The average of triglyceride levels K (254.3±49.0 mg/dL) and P1 (241.7±58.5 mg/dL) at second week. The average of triglyceride levels K (175.3±67.7 mg/dL) and P1 (181.3±40.1 mg/dL) at fourth week. Both of second and fourth week the average of triglyceride levels K and P1 were cathegorize in hypertriglyceridemia. Chitosan intake on fed inhibited increasing body weight on P2 (0.045 g) amount 53.4 g or 23.3% during 2 weeks and 63.6 g or 27.8% during 4 weeks. Chitosan intake 0.045 g on P2 decreased triglyceride levels (128.3±14.3 mg/dL) significantly than K (p=0.009) at second week. Thus, there were an opotimum dose of chitosan influence body weight and trigliceride levels.

Abstrak: Searching for a room in the building at a new area or even a frequently visited area may be a problem for some people. The purpose of this research is to develop a location based services (LBS) application which can search a place with the user’s current position as a reference. Place in this research is a room inside the building, such as classroom, laboratory, and auditorium. This research is conducted in several stages, the first is application development planning based on related references. The second is system requirement analysis, such as hardware specification and data. After that, the system is designed and implemented based on the previous two iterations of analysis, and finally, the system is tested for each function. The application is developed on Android platform using Google Maps API version two. User’s location coordinate is obtained by using assisted global positioning system ( A-GPS ) which can utilize the services from the service provider to determine the user's position at current time. This research’s result is an application that capable to show a route to the desired room along with its associated distance, travel time and room layout information.
