Judul: Penentuan Komposisi Larutan Holding Untuk Bunga Potong Pink Ginger (Alpinia Purpurata)
Abstrak: Pink ginger (Alpinia Purpurata) flower had a good prospect as cut flower .. Pink ginger quality as cut flower was a determine factor in the marketing process. Holding solution as lasting potion for the flower in a vas was one of the post harvest treatment in order to maintain the freshness and the quality of the cut flowers. Holding solution as lasting potion basically contain of three components, which were carbohydrate (sugar) as nutrition source, tamarind and material that able to prohibit microorganism expansion (germicide). The objective of this research was to obtain holding solution that extended vase life of the pink ginger cut flower (Alpinia purpurata).

Judul: Effectivity of Several Holding Solutions on Hydrangea macrophylla L. Vase Life
Abstrak: Hydrangea sebagai bunga potong memiliki umur simpan yang relatif lebih singkat dibandingkan dengan bunga lainnya. Salah satu perlakuan pascapanen yang dapat dilakukan adalah penggunaan larutan penyimpan. Penelitian bertujuan mengetahui larutan penyimpan yang dapat memperpanjang umur simpan bunga hydrangea menggunakan larutan komersial (Chrysal dan Floralife) serta beberapa larutan buatan berupa berbagai kombinasi asam sitrat dan sukrosa. Penelitian menggunakan rancangan acak lengkap (RAL) dengan faktor tunggal berupa larutan penyimpan yang terdiri atas akuades (P0), Chrysal (P1), Floralife (P2) serta kombinasi asam sitrat 300 ppm dan sukrosa 3% (P3). Hasil penelitian menunjukkan bahwa larutan penyimpan buatan dengan kombinasi asam sitrat 300 ppm dan sukrosa 3% dengan pH 3,5 memiliki efektivitas penggunaan larutan yang serupa terhadap larutan penyimpan komersial, khususnya dalam memperpanjang umur simpan dan menjaga warna bunga., Hydrangea as cut flowers has a relatively shorter vase life compared to other flowers. One of the postharvest technologies to extend the vase life of Hydrangea flowers is by using holding solutions. This research was aimed to prolong the vase life of Hydrangea macrophylla using commercially available solutions (Chrysal and Floralife) and several made up solutions containing different concentration of citric acid and sucrose. The experiment was set up in a completely randomised design (CRD) with holding solutions as a single factor, i.e. aquadest (P0), Chrysal (P1), Floralife (P2), and combination between 300 ppm citric acid and 3% sucrose (P3). The result shows that the made-up solution containing 300 ppm citric acid and 3% sucrose with a pH of 3.5 has similar effectivity as commercially available solutions, especially in extending the vase life and maintaining the flower color.

Judul: Perbandingan Metode Kekar Biweight Midcovariance dan Minimum Covariance Determinant dalam Analisis Korelasi Kanonik
Abstrak: Canonical Correlation Analysis (CCA) is a multivariate linear used to identify and quantify associations between two sets of random variables. Its standard computation is based on sample covariance matrices, which are however very sensitive to outlying observations. The robust methods are needed. There are two robust methods, i.e robust Biweight Midcovariance (BICOV) and Minimum Covariance Determinant (MCD) methods. The objective of this research is to compare the performance of both methods based on mean square error. The data simulations are generated from various conditions. The variation data consists of the proportion of outliers, and the kind of outliers: shift, scale, and radial outlier. The performance of robust BICOV method in CCA is the best compared to MCD and Classic.
