Judul: The impact of human capital investment on Indonesia’s economic growth
Abstrak: Many studies of economic growth in advanced countries confirm the importance of human capital investment. These statistical investigations indicate that output has increased at a higher rate than can be explained by only the inputs of labor and physical capital. The purpose of this study is to analyze the impact of human capital investment on the Indonesian macro economics and sectoral performances by using the Computable General Equilibrium (CGE) model. The results show that an increase in human capital investment by government (both capital and non-capital expenditures) will have positive effects on several economic indicators such as real GDP, household consumption, and real wage. While in sectoral performances, it will increase all sectoral output and labor demand.

Judul: Mengidentifikasi Kontribusi Human Capital terhadap Pertumbuhan Ekonomi Indonesia.
Abstrak: Over the past ten years, labour has been the primary contributor to economic growth as Indonesia benefits from the demographic dividend (Organization for Economic Co-operation and Development [OECD] 2021). Indonesia, though, could not rely on this advantage continually because the demographic bonus will soon dissolve (United Nations 2019). Considering this possibility, based on the structural reform simulation in Indonesia, which demonstrates that investment in human capital is not too costly compared to the growth rate it produces, the OECD encourages Indonesia to prioritize improving human capital accumulation as another factor to boost the economy. Human capital has been the object of research as one of the growth determinants since its inclusion in the growth model by Mankiw–Romer–Weil (1992), including in Indonesia. Similar to research in other countries, numerous studies about human capital and economic growth that has been done so far, exclusively emphasize the correlation between variables, that is one to one and employ static panel data, that neglect changes throughout time. Therefore, the relationship between human capital and economic growth is jointly examined in this study by employing the System General Method of Moments (SYS-GMM) to examine the dynamic growth model. Moreover, some dataset adjustments were performed to reduce the likelihood of bias and measurement error. These include limiting the research period to 2010–2019 and excluding North Kalimantan Province as a unit of observation. By applying these criteria, data on 33 provinces in Indonesia were obtained, resulting in a balanced panel dataset of 330 unit observations. After controlling for other macroeconomic variables, the research findings support the notion that human capital is the major factor influencing the economy in Indonesia, in which health attributes are proven to have a greater economic impact than education.

Judul: Membran polistirena dengan ragam suhu perendaman untuk pervaporasi alkohol
Abstrak: Polystyrene membrane with PLURONIC as porogen, can be utilized in alcohol pervaporation. The polystyrene membrane was made by reverse phase method which was started with making of polymeric mixed solution between polystyrene and PLURONIC in dichloromethane with 2 different compositions, i.e.-polystyrene :PLURONIC:dichloromethane 17:0:83 and 17:1:82. The solution was stirred up for 5 hours with ultrasonic and casted on the glass plate surface, and then it was immersed into water at 40, 50, and 60 oC. The highest pervaporation result was 90,2% alcohol purities at 50 oC immersion temperature. However, this result was not good enough because the alcohol purities was lower than the standard alcohol purities at 91,6%.
