Judul: Analisis unsur dalam butir darah hipertensi dan non-hipertensi menggunakan metode analisis aktivasi neutron
Abstrak: The composition of elements in blood is presumed to be correlated with hypertension. In this research, elements in hypertension and non-hypertension of packed blood cells were analyzed using neutron activation analysis (NAA) method. The qualitative analysis detected 34 elements in hypertension packed blood cells and 38 elements in nonhypertension blood cells. However, only 9 elements from those suitable to be reported quantitatively based on errors below 10%, i.e. Na, Cl, K, Br, Zn, Rb, Co, Fe, and Cs. The concentration of those elements in hypertension packed blood cells were 5665.87; 6460.70; 6630.71; 11.85; 29.78; 27.79; 0.56; 2522.50; dan 0.33 mg/kg, respectively. Meanwhile, the concentration of those elements in non-hypertension packed blood cells were 4615.37; 6677.14; 6657.36; 11.53; 26.87; 27.43; 0.34; 18440.4; dan 0.18 mg/kg, respectively. The result of binary logistic regression showed that Co and Cs have positive relation with hypertension. Conversely, Fe has negative relation.

Judul: Analisis Unsur dalam Butir Darah Hipertensi dan Non-hipertensi Menggunakan Metode Analisis Aktivasi Neutro
Abstrak: Komposisi unsur-unsur dalam darah diduga berkaitan dengan timbulnya hipertensi. Dalam penelitian ini, unsur dalam cuplikan butir darah hipertensi dan non-hipertensi dianalisis menggunakan metode analisis aktivasi neutron (AAN). Analisis kualitatif menunjukkan 34 unsur berhasil dideteksi dalam cuplikan butir darah hipertensi dan 38 unsur pada non hipertensi. Namun, dari jumlah tersebut hanya sembilan unsur layak dianalisis secara kuantitatif, yang memiliki kesalahan penghitungan kurang dari 10%, yaitu Na, Cl, K, Br, Zn, Rb, Co, Fe, dan Cs. Konsentrasi unsur-unsur tersebut dalam butir darah hipertensi berturut-turut sebesar 5665,87; 6460,70; 6630,71; 11,85; 29,78; 27,79; 0,56; 2522,50; dan 0,33 mg/kg. Sementara, konsentrasi dalam butir darah non hipertensi masing-masing sebesar 4615,37; 6677,14; 6657,36; 11,53; 26,87; 27,43; 0,34; 18440,4; dan 0,18 mg/kg. Berdasarkan hasil uji regresi logistik biner, unsur Co dan Cs memiliki hubungan positif terhadap timbulnya penyakit hipertensi. Sebaliknya, unsur Fe memiliki hubungan negatif.

Abstrak: Guraici Archipelago is a marine tourism destination in South Halmahera, Province of North Maluku. Landscape planning for Welcome area was intend to accomodate tourist requirement for their activities. The landscape planning specifically locate in Lelei Island which have 10,46 Ha of the area to be developed. This study was purposed to propose landscape planning in Lelei Island as an welcome area for marine tourism in Guraici Archipelago area according to its landscape and society potency to pursue the island vision to be a tourism object.The study was conducted since April 2012 until June 2012. Planning process by Simonds (2006) way used with research approach which consisted of commission, research, analysis, and sintesis. Spatial and descriptive analysis were use to determine the suitability of the space for tourism. The result showed that 55,9% of the space was high suitability for planning, 23,5 % moderate, and 20,4% was low. Site was planned consisting of 0,5 Ha welcome area (5,02%), 5,6 Ha service area (54,44%), 3,2 Ha conservation area (10,53%), and 1,1 Ha transition area (9,76%).
