Judul: Konfigurasi Program Studi di IPB berdasarkan Prestasi Mahasiswa TPB IPB
Abstrak: Biplot gives an overview of the study program configuration based on First Year students’ Achievement. The data used in this study are the scores of 14 subjects and grade point average (GPA) of first year students in academic year of 2008/2009-2010/2011. In this study, goodness of fit of the biplot is analyzed via Procrustes analysis. Data exploration is carried out using variable frequency, average score of subjects, GPA, boxplot of variables, and Spearmant’s correlation matrix. Procrutes analysis is used to measure similarity between two study program configurations according to whole data matrix, the two dimensional variable matrix. The results show that the study program configuration in academic year of 2009/2010. Moreover, the biplot obtained from the three academic years produce goodness of fit of the data matrix less than 65%. This means that there will be distortion of the images obtained from the biplot, and therefore, the conclutions should be supported by the results of data exploration. The results of this study are expected to provide information of the advantages for each study program at IPB to improve their academic quality.

Judul: Analisis Biplot dan Procrustes Terhadap Perubahan Kurikulum TPB IPB Angkatan 2010/2011 dan 2011/2012
Abstrak: Bogor Agricurtural University is one of the universitity which applied Tingkat Persiapan Bersama (TPB) program. The purpose is to make an equalization of the basic science lessons quality and understanding for the first year students so they could continue the advance education in each of their faculty. Since TPB program was applied until now, there were many changes that were made to upgrade the quality and efficiency of the program. The last change was made for the class of 2011/2012 with the change on Mathematics, Biology, Physics, and Chemistry course. This study aims is to describe and explore the impact of the curriculum changes which is applied from the class of 2010/2011 to 2011/2012. The Method is comparing the academic achievement between both class with descriptive statistical analysis : scatterplot, boxplot, and biplot and using Procrustes analysis to measure the similarity between both class. Biplot analysis map the departments as object and courses as variable. The result of this study shows that the changes of curriculum which were applied to class of 2011/2012 increase the academic achievement of IPB department’s. Procrustes analysis shows that the biplot of the class of 2010/2011 and 2011/2012 configuration have a 67.4% similarity.

Judul: Pembuatan Sabun Cair Penyanitasi Tangan Dari Ekstrak Daun Salam (Eugenia polyantha).
Abstrak: Keracunan pangan disebabkan oleh pangan yang tidak aman, yaitu pangan yang mengandung cemaran yang berbahaya baik cemaran kima, fisik, maupun mikrobiologi. Tangan manusia sebagai salah satu perantara kontaminasi silang perlu dijaga agar tetap higienis, terutama ketika menangani makanan. Sabun cuci tangan penyanitasi yang aman dibutuhkan khususnya bagi pekerja di industri pangan. Ekstrak daun salam dapat menghambat pertumbuhan mikroorganisme termasuk bakteri Gram Positif Staphylococcus aureus yang biasanya terdapat pada tangan pekerja. Kandungan antimikroba yang tedapat pada ekstrak daun salam (EDS) yaitu tanin dan flavonoid termasuk dalam senyawa fenol. Tujuan dari penelitian ini adalah untuk mengetahui konsentrasi hambat minimum (KHM) dengan penambahan ekstrak daun salam yang efisien untuk menghambat pertumbuhan bakteri Staphylococcus aureus dan mereduksi total mikroba pada tangan pekerja industri pangan. Pembuatan EDS adalah dengan metode maserasi, penetapan KHM terhadap Staphylococcus aureus dengan metode dilusi, formulasi sabun cair dengan ekstrak daun salam berdasarkan hasil KHM, evaluasi efektivitas sabun cair untuk mereduksi Staphylococcus aureus dan total mikroba di tangan. Rendemen pembuatan EDS adalah sebesar 15,42% (w/v), KHMekstrak daun salam terhadap Staphylococcus aureus adalah konsentrasi 4%. Sabun cair yang diformulasikan dengan EDS 4% memiliki nilai pH 7,24 dan EDS 8% memiliki nilai pH 7,83 setelah penambahan asam fosfat. Bobot jenis pada sabun cair EDS 4% sebesar 1,0290, sabun cair 8% sebesar 1,0288. Reduksi Staphylococcus aureus di tangan pada pencucian dengan sabun EDS 4% dan 8% sebesar satu log, sedangkan reduksi pada total mikroba kurang dari satu log. Sabun cair penyanitasi dengan tambahan ekstrak daun salam belum efektif untuk sanitasi pada tangan.
