Judul: Hubungan Tata Kelola Pemerintahan, Infrastruktur dan Pertumbuhan Ekonomi di Indonesia
Abstrak: Good governance has an important role to promote economy growth. The study relationship between governance with economic growth using aggregate data in Indonesia did not find a significant relationship. Therefore, the purpose of this study was to explore the influence of governance on economic growth, both direct effects and indirect effects through infrastructure provision. By employing two stages least square method on the data 245 districts/cities in 2010, the results of this study indicate that governance affects economic growth through the provision of road infrastructure and the electricity infrastructure. A discussion of public policy and the firmness of the regional head on anti-corruption measures improving road infrastructure, while the duration of roadworks negatively affect the provision of road infrastructure. Facilitation efforts by the local government will increase the supply of electricity infrastructure. Governance affects economic growth directly through government policy that does not increase costs for businesses.

Judul: Dampak Pembangunan Infrastruktur dan Aglomerasi Industri terhadap Pertumbuhan Ekonomi Regional di Indonesia
Abstrak: In general, the Indonesia’s economic growth is significantly improved recently but the increase rate is different in each region which entitles to high regional disparity. One of the reasons why it occurs is because of the difference of infrastructure development in every region. Beside, the centralization of the economic activities tends to cause this issue. This study intends to analyze the effect of infrastructure development and industrial agglomeration to the regional economic growth in Indonesia. Based on productivity function of Cobb-Douglas model, the fixed effect model is used as data panel method which includes a range of data from 26 provinces in 1991-2007. The estimation in this study ensues to the influence of labor, investment, human capital, physical infrastructures (electricity and roads), industrial agglomeration, and economic crisis in 1997, while water infrastructure is not significant. Due to the estimation data result, the characteristic of production activity in Indonesia is labor-based with the labor elasticity rate of 0,27 higher than investment elasticity which is 0,10. Human capital variable holds the biggest effect with 0,34 score. Physical infrastructure (electricity and roads) is significantly influential with electricity elasticity indicates 0,33 score, higher than roads elasticity score of 0,13. In addition to this, industrial agglomeration contributes positive effect on economic growth which is indicated by 0,04 elasticity score. On the other hand, the negative coefficient score as a result of economic crisis in 1997 obstructs the economic growth. To sum up, variables which deliver positive influence for regional economic growth in Indonesia are human capital, electricity, roads, and industrial agglomeration. Furthermore, distribution of infrastructure development, education, and centralization of the economy activity should be applied in order to reduce regional disparity.

Judul: Formulasi Campuran Minyak Atsiri Sebagai Repelen Nyamuk Aedes aegypti
Abstrak: Minyak Atsiri merupakan minyak yang memiliki senyawa kompleks yang bermanfaat salah satunya sebagai penolak serangga seperti nyamuk. Penelitian ini bertujuan untuk mengetahui formula campuran minyak atsiri terbaik untuk sediaan penolak nyamuk. Minyak atsiri yang digunakan dalam penelitian ini adalah minyak atsiri sereh wangi, sereh dapur, kayu putih dan lavender. Minyak atsiri yang diperoleh dilakukan karakterisasi warna, bobot jenis, indeks bias dan kelarutan dalam alkohol. Warna yang dihasilkan sesuai dengan SNI yaitu kuning pucat sampai kuning jernih, bobot jenis yang dihasilkan 0.8125-0.9114, indeks bias yang dihasilkan 1.4568-1.4665 dan larut dalam alkohol. Minyak atsiri yang digunakan tersebut menghasilkan 7 formula, yaitu formula A1-A5, formula B1- B5, formula C1-C5, formula D1-D5, formula E1-E5, formula F1-F5, dan formula G1-G5. Uji organoleptik yang dilakukan pada formula tersebut menunjukkan hasil bahwa formula yang banyak disukai adalah formula E3, G3 dan F3. Semua minyak terpilih dilakukan uji repelen (daya tolak) terhadap nyamuk untuk mengetahui efektivitas dari campuran minyak tersebut dengan cara mencampurkan dengan VCO. Hasil dari uji repelen formula E3 (minyak sereh dapur, sereh wangi dan lavender) paling efektif dibandingkan formula F3 dan G3. Nilai daya proteksi yang dihasilkan dari formula E3 mencapai diatas 90% sampai jam ke-4.
