But 21.08% Bidik Misi student of IPB got the GPA below the GPA minimum. The Ordinal logistic regression model can be use as the model to predict the study Achievement for the future Bidik Misi student and to determine the variabel which have significant influence to the study achievement. Variabel that have significant influence to the study achievement are gender, high school status, present of mother status, departemen, national exam grade (UN), income, and size of family.

The first group is the student who have the GPA below 2.75, the characteristic for this group are the high school status not from state high school, the national exam score below the average, and from the department cluster which have middle and low TPB GPA. The second group is the student who have the GPA 3.50 higher, The Characteristic for this group are the high school status from state high school, the student who came from java, the national exam score higher than average, and from the department cluster which have high TPB GPA.

Judul: Sintesis 1-Kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai Prekursor Asam (S)-(+)-(6-Metoksi-2-naftil)propanoat
Abstrak: Senyawa 1-kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai prekursor asam (S)-(+)-(6-metoksi-2-naftil)propanoat disintesis dari bahan awal 2-metoksinaftalena. Tahapan sintesis diawali dengan klorinasi menggunakan 2 jenis pereaksi klorinasi, yakni isosianurat terklorinasi dan NaOCl. Klorinasi dengan isosianurat terklorinasi berhasil menyintesis 1-kloro-2-metoksinaftalena sebagai produk monoklorinasi melalui pencirian dengan kromatograf gas-spektrometer massa (GC-MS). Nisbah konversi produk paling efisien diperoleh pada laju penambahan 2.5 mmol/jam. Sebaliknya, klorinasi dengan NaOCl menghasilkan produk triklorinasi. 1-Kloro-2-metoksinaftalena selanjutnya diasilasi dengan propanoil klorida, tetapi analisis dengan GC menunjukkan bahwa produk asilasi tidak terbentuk. Sistem bebas-air diperlukan untuk keberhasilan proses asilasi tersebut.
