Judul: Ketahanan Pangan di Kawasan Timur Indonesia
Abstrak: This study aims at analyzing the dynamics of food security and the factors that influence food security in Eastern Indonesia. Food security levels for household are grouped into four, namely food secure, vulnerable, questionable and food insecure. The methodology used is panel data tobit model of 190 districts/cities in the Eastern Indonesia from 2008 to 2010. Results of the research showed that overall consumption of calories and protein in the KTI is below the standard limit of nutritional adequacy. The shares of food expenditures of the eastern Indonesia population are greater than for non-food expenditures. Based on the classification of the food security degree, the majority of households in KTI are including the vulnerable category. Food security is affected by percentage of poor people, GRDP per capita, female illiteracy and average of school. Food availability does not guarantee an increasing in the food security degree in the Eastern Indonesia, but food security is also determined by the accessibility and utilization of food. Education has the highest contribution in improving food security in the KTI. It is seen from the value of the elasticity of average of school the most high.

Judul: Determinants of Household Food Security: A Comparative Analysis of Eastern and Non-Eastern Indonesia
Abstrak: Food security at the national, regional and district level do not ensure food security at household level. The facts that although at a national, regional and districts level the status of food security is assured, but in the region and districts is still found the food insecure households. Moreover, domination of Indonesian food policies which mostly emphasize in rice production and keep the price of rice remained low lead to the provinces with high in rice production but also high problems of hunger and malnutrition. In 2009, Indonesian Food Security Council issued a Food Security and Vulnerability Atlas (FSVA) which stated that there were 100 districts in Indonesia, which were most vulnerable to food insecurity based on the composite food security index. Of the 100 districts, 79 of which (79 percent) were located in Eastern Indonesia. This shows that the implemented food policy in Indonesia is still emphasized in the rice production and have not able to tackle, especially the problems of availability, access, utilization and stability of food security. Therefore, handling of food security in Indonesia must involve all factors, including food availability, food accessibility, food utilization, and food stability simultaneously. Based on the above description, the objectives of this study are: 1) To analyze the condition of household food security in Eastern Indonesia compared to non-Eastern Indonesia 2) To analyze the determinants of household food security in Eastern Indonesia compared to non-Eastern Indonesia. The data used in this study are SUSENAS module of consumption and expenditure which was collected in July 2008 and Susenas kor 2008. Both data cover 285,904 households from Eastern and non-Eastern region. The status of household food security is identified by two indicators: per adult-equivalent calorie availability and per adult-equivalent share of expenditure. Ordinal logistic regression used as the method to analyze the data. On the average, the calorie availability of households in Eastern and non-Eastern Indonesia has been already more than the requirements to be food secure households (80 percent). However, the share of food expenditures is also still more than 60 percent lead to the food vulnerable households. The households with this characteristic are susceptible to the shock. The problem of food vulnerability is not only applied in Eastern Indonesia, but also in non-Eastern Indonesia. The factors of expenditure equivalent, gender of household head, age of household head, education of household head, main occupation of household head, household location, and household size are all significant determinants of household food security in Eastern and non-Eastern Indonesia. The difference is in the factors of access to electricity which is not significant in Eastern Indonesia and access to loan and access to safe drinking water which are only significant in non-Eastern Indonesia.

Judul: Sintesis Nanorod Seng Oksida (ZnO) dengan Metode Sonokimia
Abstrak: Gelombang ultrasonik telah digunakan untuk membantu sintesis ZnO. ZnO terbentuk dari campuran ZnAc dan NaOH. ZnO disintesis dengan variasi konsentrasi ZnAc 0.5 M ( ZnO 1:1 ) dan 1.5 M ( ZnO 3:1 ) yang dicampurkan dengan NaOH konsentrasi 0.5 M. Sampel yang diporoleh dikarakterisasi dengan XRD dan SEM. Karakterisasi difraksi sinar-X menunjukkan bahwa struktur kristal ZnO yang dihasilkan merupakan heksagonal dengan pertumbuhan yang dominan pada orientasi bidang nonpolar a dengan indeks hkl 101. Kristalinitas dan kemurnian kristal ZnO 1:1 lebih baik dibandingkan ZnO 3:1 ditunjukan dengan intensitas puncak difraksi sinar-X yang lebih tinggi, sempit dan tajam. Untuk ukuran kristalit ZnO 1:1 mempunyai rata-rata ukuran kristalit 30.57 ± 4.31 nm sedangkan ZnO 3:1 mempunyai ukuran rata-rata 20.25 ± 7.12 nm. Dari ukuran kristal yang terbentuk partikel ZnO termasuk nanokristal. ZnO 1:1 terbentuk batang-batang nano (nanorods) sedangkan pada ZnO 3:1 tidak terbentuk batang-batang nano (nanorods). Untuk ukuran morfologi, ZnO 1:1 mempunyai rata-rata ukuran butiran kristal 230 nm dan lebih besar dibandingkan ukuran ZnO 3:1 yang mempunyai rata-rata ukuran butiran kristal 50 nm.
