PENGARUH PENGGUNAAN SILICA FUME DENGAN MATERIAL BATU LATERIT SEBAGAI SUBTITUSI AGREGAT KASAR TERHADAP KUAT TEKAN BETON
No full textMaterial penyusun beton umumnya terdiri dari semen, agregat kasar, agregat halus, dan air. Agregat kasar yang dapat digunakan adalah batu split atau dapat juga menggunakan campuranan tara batu split dengan material lokal lain seperti batu Laterit yang terdapat pada Desa Mulawarman Kecamatan Tenggarong Seberang. Untuk meningkatkan mutu beton, maka digunakan Silica Fume sebagai bahan tambah. Tujuan utama penelitian ini untuk mengetahui pengaruh penggunaan Silica Fume sebagai subtitusi semen dan batu Laterit terhadap nilai kuat tekan beton. Pada penelitian ini dibuatlah beton normal sebagai acuan dan beton dengan agregat kasar di subtitusi sebesar 20% dengan batu Laterit serta semen disubtitusi dengan Silica Fume dengan variasi 0%, 5%, 7.5%, 10%, dan 12.5%. Dari hasil pengujian kuat tekan beton diperoleh beton dengan subtitusi agregat kasar 20% dan subtitusi semen dengan Silica Fume 10% pada umur 28 hari sebesar 26.47 MPa, nilai ini melebihi kuat tekan beton normal yaitu 26.26 MPa dan beton dengan Laterit 20% dan Silica Fume 0% yaitu 22.03 MPa. Jadi kesimpulan penggunaan Silica Fume dapat meningkatkan kuat tekan beton dengan subtitusi batu laterit menjadi lebih tinggi dibandingkan dengan kuat tekan beton normal
Policy Brief
No full textAdolescence is a dynamic period of
biological development and social change, and also a period
when adolescent girls are at risk of school dropout, early
marriage, pregnancy, and gender-based violence. Adolescents
have the highest unmet need for family planning in
Bangladesh, and married adolescents have a significantly
lower contraceptive prevalence rate than other age groups,
leading to a high adolescent fertility rate. The Government
of Bangladesh developed a national strategy for adolescent
health 2017-2030 and a costed action plan to improve
adolescent health, including sexual and reproductive health.
The Strategy addresses overall health needs of adolescents,
including menstrual hygiene management, prevention of
violence and mental health. The Government of Bangladesh is
currently implementing the 4th Health, Population and
Nutrition Sector Program which includes support for a
school-based adolescent health and nutrition program.
Furthermore, programme implementers often work in silos and
focus on single platforms, i.e. at the health facility,
school, or community levels. Presently adolescents receive
sexual and reproductive health information and services
largely from private sector providers with variable quality
Towards a Framework for impact pathways between NCDS, Human Capital and Healthy Longevity, Economic and Wellbeing Outcomes
No full textNon-communicable diseases (NCDs) are
one of the major health and development challenges of our
time, impacting not only higher income countries, but
increasingly lower income ones as well. It is important to
define an operational framework for addressing NCDs in low-
and middle-income countries. The healthy longevity framework
visualizes three main channels through which NCDs may impact
end outcomes: (i) the macroeconomic/savings channel; (ii)
the fiscal channel; and (iii) the human capital channel.
Within the human capital channel, a life course perspective
is vital as NCDs impact human capital from conception
through to old age, and across generations. NCDs compromise
the entire trajectory of HC, from its formation to
deployment to protection and preservation
Do Capital Incentives Distort Technology Diffusion? Evidence on Cloud, Big Data and AI
No full textThe arrival of cloud computing provides firms a new way to access digital technologies as digital services. Yet, capital incentive policies present in every OECD country are still targeted towards investments in information technology (IT) capital. If cloud services are partial substitutes for IT investments, the presence of capital incentive policies by unintentionally discourage the adoption of cloud and technologies that rely on the cloud, such as artificial intelligence (AI) and big data analytics. This paper exploits a tax incentive in the UK for capital investment as a quasi-natural experiment to examine the impact on firm adoption of loud computing, big data analytics and AI. The empirical results find that the policy increased investment in IT capital as would be expected; but it slowed firm adoption of cloud, big data and AI. Matched employer-employee data shows that the policy also led firms to reduce their demand for workers that perform data analytics, but not other types of worker
Disability and Inclusion

Government of Ukraine is strengthening the protection of
vulnerable groups to ensure inclusive service delivery
Spring Meetings 2024
No full textThis edition of the Macro Poverty
Outlooks periodical contains country-by-country forecasts
and overviews for GDP, fiscal, debt and poverty indicators
for the developing countries of Sub-Saharan Africa.
Macroeconomic indicators such as population, gross domestic
product and gross domestic product per capita, and where
available, other indicators such as primary school
enrollment, life expectancy at birth, total greenhouse gas
emissions and inflation, among others, are included for each
country. In addition to the World Bank’s most recent
forecasts, key conditions and challenges, recent
developments and outlook are briefly described for each
country in the region
Long-Term and Lasting Impacts of Personal Initiative Training on Entrepreneurial Success
No full textA randomized experiment in Togo found
that personal initiative training for small businesses
resulted in large and significant impacts for both men and
women after two years (Campos et al, 2017). This paper
revisits these entrepreneurs after seven years, and finds
long-lasting average impacts of personal initiative training
of $91 higher profits per month, which is larger than the
2-year impacts. However, these long-term impacts are very
different for men and women: the impact for men grows over
time as they accumulate more capital and increase
self-efficacy, whereas the impact for women dissipates, and
capital build-up is much more limited
Does the Source of FDI Matter? The Case of Tax Havens
No full textThis paper estimates the benefits of FDI for firm performance, differentiating source countries between tax havens and non–tax havens. Using longitudinal data on more than 300,000 initially domestic firms in Ukraine between 1999 and 2013 and employing propensity score matching and panel data methods, this study finds that firms acquired by non–tax haven foreign investors experience substantial increases in employment, productivity, exports, and wages, but the gains are much lower and shorter-lived for firms receiving FDI from tax havens. These findings, based on econometric analysis of nearly the universe of Ukrainian businesses, are consistent with macroeconomic studies and anecdotal evidence that much of the tax-haven FDI in Ukraine actually represents domestic ownership channeled through offshore companies. This round-trip FDI results in negligible effects on firm performance and, at a macro level, it overstates the amount of genuine FDI flows into Ukraine
How Transfer Duration and Frequency Contribute to Outcomes
No full textAs a part of “Evidence at Your Fingertips Series”, this note summarizes the impacts of cash transfers based on the duration and frequency of transfers. The review is largely based on the impact evaluations published in the past decade, finding that the impact of cash transfers varies based on duration, depending on whether they are distributed over a short (24 months or less) or long (more than 24 months) period. Cash transfers distributed over a long period provide predictability that is associated with greater impact, particularly with transfers distributed to improve children’s health, nutrition and education, and employment and labor. A longer duration of transfers allows for households to plan, which in turn allows households to engage in riskier yet more-profitable income-generating activities, when available. While the evidence suggests that frequency of cash disbursements alone does not significantly affect outcomes, it is important to remember that the confluence of size, frequency, and duration of cash transfers may produce different results than any single factor in isolation
Making Public Data Count
No full textThis report is part of a collection
examining how analytics using government microdata is
revolutionizing public administration throughout the world.
The collection is based on The Government Analytics
Handbook, a comprehensive guide to using data to understand
and improve government. The reports in this collection aim
to help public servants apply lessons from the Handbook to
their own administrations by describing the unique
opportunities and challenges for government analytics that
arise in different regions. No two regions, countries,
administrations, or organizations are alike - that’s why
using microdata to measure, understand, and improve
government is so important! The general principle of the
Handbook is as follows: governments across the world make
thousands of personnel management decisions, procure
millions of goods and services, and execute billions of
processes each day. They are data rich. And yet there is
little systematic practice to date that capitalizes on these
data to make public administrations work better. This means
that governments are missing out on data insights to save
billions in procurement expenditures, recruit better talent
into government, and identify sources of corruption - to
name just a few! The Handbook seeks to change that. It
presents frontier evidence and practitioner insights on how
to leverage data to make governments work better. Covering a
range of microdata sources - such as administrative data and
public servant surveys - as well as tools and resources for
undertaking analytics, it transforms governments to take a
data-informed approach to diagnose and improve how public
organizations wor
