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.

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.

Abstrak: Glycerol is a by-product from palm olein biodiesel industry which could be value-added to obtain various products. One of the alternatives is to modify glycerol become glycerol ester oleat. Before processing, glycerol was first refined using 5% (v/v) phosphoric acid 85%. The refinery showed that glycerol content was increased from 49% to 80%. Glycerol was then esterified with oleic acid and catalyst methyl ester sulfonic acid (MESA) to obtain glycerol ester. Esterification was conducted at 240°C and nitrogen atmosphere using 200 rpm of mixing for 90 minutes. The best catalyst concentration used in esterification process is at 0,5% and resulting glycerol ester oleat with acid number 48,07 mg KOH/g sample, density of 0,9124 g/cm3, viscosity 68,32 cP (25°C), kinematic viscosity 36 cSt (40°C), flash point 230°C and pour point -15°C.
