Abstract

Background: Diabetes melitus  is  one  of  the  degenerative  disease, which  is  the  amount will  increase  in  the future  and needs  serious  treatment  because  of  complications cause  it. Diet  is  the main  therapy  to  improve  and maintain  the  blood sugar  in normal  rate. For helping  the diabetic  patient doing  the  new diet  therapy  in  their daily living  is depend  on  their  attitude and  behavior. The  long  lasting  obedience  in  preparing  the meals  is  one of  the most challenge  in diet  therapy.Method: The  aim  of  this  research  is  for  identificated  the  differences  of  behavior and  the  obedience  between male  and  female who have  diabetes melitus  in diet  therapy with  descriptive comparative  and  independent  t-test with SPSS  version  12.0,Result: The  result of  this  research shows 55,0% males and 70,0%  females have bad behavior of  the obedience in  diet  therapy. Beside  that  80,0% males  and  70,0%  females are  obey  to  follow diet  therapyConclusion: From the  result of  this research shows P = 0,093, because P > 0,05,  the conclusions  is there  is no differences of  behavior  in  obedience diet  therapy between male  and  female.Keywords:  behavior,  obedience,  diet, diabetes melitus

Abstract

Abstract The district of Central Aceh is one of district located in the highlands of Gayo. The land and environtmant are very promising which is really potential to development of farming sector primarily coffee plant. Information on moisture groundwater is necessary to improve the potential ground for the coffee plant. Coffee plants are already known suitable developed in the district of Central Aceh. But, information on the status of groundwater in certain kind of soil unavailable, although the availability of water can be done with the irrigation. The results showed that among 3 types of studied soils are that andisol, ultisol and inceptisol and the highest water available is ultisol dominated by a non cultivation. Even andisol having value the availability of water is more stable, this can be seen from the water available that is not very different between land cultivation and non cultivation. While other land types that Ultisol and Inceptisol only have water available on of non cultivation only. If it is associated with the availability of water in the coffee plant is then the Andisol is most suitable because soil water on the two different locations aren’t different .

Abstract

Mono-digliserida (MGDG) disintesis melalui reaksi transesterifikasi enzimatis menggunakan minyak inti sawit mentah (MISM) dan gliserol sebagai substrat. Reaksi berlangsung pada temperatur 30oC, rasio mol MISM : gliserol = 1:2 mol, waktu reaksi 8 jam dan rasio enzim Candida antartica : MISM = 0,05% (b/b). MISM dan gliserol tidak mudah larut sebab memiliki polaritas yang berbeda. Untuk meningkatkan homogenitas kedua substrat, maka ditambahkan n-heksan sebagai pelarut dalam berbagai rasio, yaitu 1:1 – 1:10 (% b/v) terhadap massa MISM. Tujuan penelitian ini adalah mengamati pengaruh n-heksan terhadap aktifitas katalitik dari enzim Candida antartica untuk meningkatkan konversi substrat. Konversi substrat diukur secara kuantitatif berdasarkan persentase penurunan bilangan asam. Sebagai kontrol terhadap reaksi enzimatis, dilakukan reaksi non enzimatis dengan menggunakan kondisi reaksi yang sama. Dari hasil penelitian diketahui bahwa enzim Candida antartica mampu menahan n-heksan dalam sistem campuran reaksi hingga batasan tertentu. Konversi substrat optimal diperoleh pada rasio MISM : n-heksan = 1:3 (b/v) sebesar 58,3% dengan kadar bilangan asam akhir = 2,275%. Penggunaan rasio MISM : n-heksan diatas 1:3 (b/v) menunjukkan penurunan konversi substrat karena terjadi toksisitas pada enzim Candida antartica yang meningkatkan rigiditas sisi aktif enzim. Produk dengan konversi optimal kemudian dianalisis menggunakan metode kromatografi gas dan diperoleh total yield MGDG sebesar 56,9116%, dengan komposisi MG = 8,9574% dan DG = 47,9542%.
