Judul: Penerapan Biplot pada Pemetaan Sumber Daya Kesehatan Antarprovinsi di Indonesia
Abstrak: Wellbeing and human development has been the attention of governments. Therefore UN provides a standard measurement of human development called Human Development Index. The Human Development Index is based on three dimensions: life expectancy, knowledge and decent living. The purpose of this paper is to provide an overview of provincial mapping based on health facilities and health workers. The provincial mapping is done using biplot. The result of goodness of fit of the biplot is 93.06% for health facilities and 70.97% for health workers. The provincial mapping shows that there are five groups of provinces based on health facilities variables and five different groups of provinces based on health workers variables.

Judul: Pemetaan Provinsi di Indonesia Berdasarkan Produk Domestik Regional Bruto Menggunakan Analisis Biplot
Abstrak: Government has a responsibility for maintaining welfare development of its people. One of the indicators that can be used to measure human development is the human development index (HDI). This index was created based on three dimensions, i.e. dimension of life expectancy, knowledge and standard of decent living. This paper provides an overview of mapping the provinces based on independent sectors of business field. The provincial mapping is done using biplot analysis. Biplot analysis presents a low-dimensional graphical display, which describes relationship between high-dimensional variables and objects. Provincial mapping can be used to obtain an overview of development between provinces. The result of biplot analysis is able to explain 85.22% information contained in the data, which is called its goodness of fit. Based on the biplot visualization, five groups of provinces are obtained. In the first group, Jakarta has a value above average on the financial sector. On the second and third groups, the agricultural sector contributes significantly to gross regional domestic product. Meanwhile, in the fourth group, Riau and East Kalimantan are the biggest contributor to the trade sector. Finally, in the fifth group, all of the provinces have gross regional domestic product value below the average in all sectors.

Judul: Synthesis of CaTiO3 by Using Eggshell as Source of CaO.
Abstrak: Selama ini, cangkang telur hanya menjadi limbah yang berpotensi mencemari lingkungan tanpa dimanfaatkan lebih lanjut. Tingginya kandungan CaCO3 menjadikan cangkang telur sebagai komoditas yang berpotensi sebagai prekursor dalam sintesis material, seperti kalsium titanat (CaTiO3). CaTiO3 sering digunakan sebagai bahan dielektrik untuk kapasitor, selain itu juga berfungsi sebagai katalis pada proses fotokatalis dan fotoluminesens. CaTiO3 dapat disintesis dengan mereaksikan CaO dari kalsinasi cangkang telur dan TiCl4 melalui metode hidrotermal. Sintesis dilakukan pada 3 kondisi pH, yaitu pH 1, 4, dan 14, dengan suhu 150 oC selama 8 jam. Berdasarkan hasil analisis difraksi sinar-X, sintesis pada pH 1 dan pH 4 hanya menghasilkan kristal TiO2. Kristal CaTiO3 berhasil disintesis pada kondisi pH 14. Hasil uji penganalisis ukuran partikel menunjukkan bahwa kristal CaTiO3 yang terbentuk masih belum homogen dengan ukuran kristal 400–1400 nm.
