"Pemeriksaan golongan darah ABO terhadap sampel saliva dapat dilakukan pada individu sekretorik, yaitu individu yang mampu mensekresikan antigen-antigen golongan darahnya ke dalam berbagai cairan tubuh termasuk saliva. Terdapat berbagai faktor yang dapat mempengaruhi hasil pemeriksaan golongan darah menggunakan saliva, diantaranya faktor temperatur dan durasi waktu penyimpanan. Tujuan penelitian : Membandingkan hasil pemeriksaan golongan darah terhadap sampel saliva segera dengan sampel saliva yang disimpan selama 1 jam pada temperatur 7°C. Metode : Pada penelitian ini dilakukan pemeriksaan golongan darah dengan teknik absorpsi-inhibisi menggunakan 20 sampel saliva dari 10 orang individu sekretorik bergolongan darah A, B, atau AB yang dilakukan pada periode waktu Oktober hingga November 2007. Hasil penelitian : Pemeriksaan golongan darah dengan sampel saliva segera menunjukkan kesesuaian 100%, sedangkan pada pemeriksaan sampel saliva yang disimpan selama 1 jam pada temperatur 7°C kesesuaiannya hanya 60%. Kesimpulan : Pemeriksaan golongan darah menggunakan saliva segera menunjukkan hasil yang tepat. Namun terjadi penurunan ketepatan pada hasil pemeriksaan setelah penyimpanan sampel selama 1 jam dengan temperatur 7°C.

ABO blood group can be determined from secretoric individual, who has the ability to secrete A, B, or O antigen to the body fluids including saliva. However, there are factors affecting the result of blood group examination using saliva including temperature and time duration of sample storage. Objective : To compare the result of blood group examination from immediate saliva samples with saliva stored at 7°C for 1 hour. Method : Twenty saliva samples from 10 secretoric individuals with A, B, or AB blood group were examined using absorption inhibition technique from October until November 2007. Result : Blood group examination results using immediate saliva samples were 100% correct. On the other hand, the results from saliva samples stored for 1 hour at 7°C were 60% correct. Conclusion : Blood group examination using immediate saliva samples showed the most accurate results. After 1 hour, delayed saliva sample examinations at cool temperature (7°C) showed a decrease accuracy in blood group examination results."

ABO blood group can be determined from secretor individual, who has the ability to secrete A, B, or O antigen to the body fluid including saliva. However, there are factors affecting the result of blood group examination using saliva including temperature and time duration of sample storage.

Objective : To compare the result of blood group examination from immediate saliva samples with saliva stored at 15°C for 1 hour.

Method : Twenty saliva samples from 10 secretoric individuals with A, B, or AB blood group were examined using absorption inhibition technique from October until November 2007.

Result : Blood group examination results using immediate saliva samples were 100% correct. On the other hand, the results from saliva samples stored for 1 hour at 15°C were 80% correct.

Conclusion : Saliva samples should be tested immediately in order to get the most accurate results. After 1 hour, delayed saliva sample examinations at 15°C showed a decrease accuracy in blood group examination results."

"[Pada penelitian ini, serat ijuk dihancurkan dan diayak ukuran 40 # setelah itu serat ijuk diberi perlakuan kimia dengan NaOH 2 % selama 1 jam, KMnO4 0,1 N selama 15 menit, dan NaClO 5 % selama 5 jam dengan tujuan mendapatkan selulosa kristalin. Setelah itu dilakukan proses pencampuran kering (hotmelt mixing) antara polipropilen dengan serat ijuk hasil perlakuan kimia dengan 7,5 % volum serat ijuk terhadap polipropilen dengan variabel temperatur 160°C, 165°C, dan 170°C dan variabel waktu pencampuran 15 menit dan 20 menit. Setelah itu dilakukan pengujian uji FTIR buat serat, sedangan buat komposit adalah uji tarik, uji STA, uji XRD, dan uji FE-SEM hal ini dilakukan untuk mendapatkan sifat kristalinitas dan mekanik dari komposit polipropilen ini. Hasil penelitian menunjukkan bahwa serat ijuk hasil perlakuaan lebih kristalin dari pada serat ijuk tanpa perlakukan, polipropilen dengan serat ijuk hasil perlakuaan kimia cukup kompatibel terhadap polipropilen, dari penelitian didapatkan sifat kristalinitas terbaik pada variabel 165°C selama 20 menit. Dan yang memiliki sifat kekuatan tarik paling baik adalah variabel 170°C selama 20 menit, sedangkan yang memiliki % elongasi paling baik adalah dengan variabel 160°C 20 menit.

In this work, palm fiber crushed and sieved size 40 # after the palm fiber chemically treated with 2% NaOH for 1 hour, 0.1 N KMnO4 for 15 minutes, and 5% NaClO for 5 hours in order to obtain crystalline cellulose. Once that is done the dry mixing (hotmelt mixing) between polypropylene and palm fiber chemical treatment results with 7.5% volume of the palm fiber and polypropylene with a variable temperature of 160°C, 165°C and 170°C and a variable time mixing 15 minutes and 20 minutes. After it was examined FTIR test for fiber, while the composite is made tensile test, STA test, XRD test and FE-SEM test this is done to obtain crystallinity and mechanical properties of polypropylene composites this. The results show that fiber perlakuaan results more crystalline fibers than untreated palm fiber, polypropylene and palm fiber chemistry results treatment compatible enough to polypropylene, crystallinity of the research showed the best properties on the variable 165 ° C for 20 minutes.
