Judul: Pengaruh Belanja Pemerintah Daerah terhadap Pertumbuhan Ekonomi dan Kemiskinan Kabupaten/Kota di Provinsi Banten
Abstrak: Economic growth is one measure of economic development. The high economic growth and low poverty indicates that an area has good public prosperity. To get the high economic growth and low poverty required the maximum role of government, by government expenditure. The purpose of this study was to explain the development of government expenditure and analyzed the influence of government expenditure on economic growth and poverty in Banten Province. This research uses descriptive method and panel data on 8 districts/cities in Banten Province in the periode of 2009-2012. The result indicate that the government expenditure in Banten Province always increase. Based on the model in analysis, goods and service expenditure and capital expenditure have a positive effect and significant contributions to the regional economic growth and also have a negative effect and significant contributions to the poverty.

Judul: Effect of Regional Expenditures and Regional Financial Independence on Economic Growth in West Kalimantan Province
Abstrak: Pertumbuhan ekonomi merupakan peningkatan output dari waktu ke waktu dan menjadi salah satu indikator dalam mengukur keberhasilan pembangunan. Pertumbuhan ekonomi yang tinggi mengindikasikan suatu daerah menuju kondisi yang lebih baik. Untuk mewujudkanya, diperlukan peran pemerintah dalam alokasi anggaran sesuai dengan peraturan perundang-undangan. Penelitian ini bertujuan menganalisis pengaruh belanja pemerintah daerah dan kemandirian keuangan daerah terhadap pertumbuhan ekonomi di kabupaten/kota Provinsi Kalimantan Barat dari tahun 2015-2019. Metode analisis yang digunakan adalah regresi data panel dengan pendekatan Fixed Effect Model (FEM). Hasil analisis regresi data panel menunjukkan bahwa belanja modal, rasio PAD, belanja kesehatan, belanja pendidikan, dan tingkat pendidikan berpengaruh signifikan terhadap pertumbuhan ekonomi. Adapun belanja modal dan belanja pendidikan berpengaruh negatif terhadap pertumbuhan ekonomi di kabupaten/kota Provinsi Kalimantan Barat., Economic growth is an increase in output from time to time and is one of the indicators in measuring the success of development. High economic growth of an area towards better conditions. To make it happen, the government's role in budget allocation is needed in accordance with the laws and regulations. This study aims to analyze the effect of local government spending and independence on regional finances on economic growth in districts/cities of West Kalimantan Province in 2015-2019. The analytical method used is panel data regression with Fixed Effect Model (FEM) approach. The results of panel data regression analysis show that capital expenditure, PAD ratio, health expenditure, education expenditure, and education level have a significant effect on economic growth. Meanwhile, capital expenditures and education expenditures have a negative effect on economic growth in the districts/cities of West Kalimantan Province.

Judul: Pemurnian dan karakterisasi protein inhibitor RNA helikase virus hepatitis C
Abstrak: Hepatitis C virus (HCV) infection is the second most common chronic viral infection in the world with global prevalence. This infection is contribution to chronic hepatitis and liver cirrhosis, often leading to hepatocellular carcinoma. There is no effective drug and vaccine available against HCV. The current standard treatment, a combination of pegylated interferon-α with ribavirin, is limited by its suboptimal response rate in a significant patient population, side effects, and affordability. Therefore, development of effective drug is needed. One approach to find out the candidate of antiviral drug is to discover the inhibitor of enzyme that essential for virus replication, such as RNA helicase. Streptomyces chartreusis 5-095 produce the inhibitor of HCV RNA helicase. The aim of this study was to purify the protein inhibitor which has inhibition activity against ATPase activity of RNA helicase HCV from S. chartreusis 5-095. The supernatant of culture S. chartreusis 5-095 exhibited high inhibiton activity against ATPase activity of RNA helicase HCV (approximately 72%) at 10 days of incubation. The extracellular protein inhibitor was partially purified by procedures of precipitation with ammonium sulfate to 65% saturation and gel filtration (Sephadex G50) using methanol water solution (4:6) as an eluen. The purity of protein inhibitor was monitored by SDS PAGE. The protein inhibitor showed a relative molecular mass were estimated to be 14 kDa and increased the purity 23,08 fold than those of the crude protein. The specific activity and IC50 after purification were 13,1338 U/mg and 0,0767 mg/mL, respectively. The activity of purified protein inhibitor showed its stability over pH range from 5-8 and optimum at pH 7,4. The inhibition activity showed its stability up to 70% at temperature 100 oC. The purified protein inhibitor relatively stable its activity at storage in the range of -20 oC to room temperature for 35 days.
