Study of rhombohedral tricalcium phosphate in hexagonal crystal structure family on the sample prepared by the sol-gel route and the effect of calcination temperature

Abstract The effect of the calcination temperature at 800 and 1000 °C on the stable formation of the tricalcium phosphate with rhombohedral structure in the system of the hexagonal crystal family was determined, while its precursor was made from limestone obtained from nature in the Lumajang district, Indonesia. The rhombohedral tricalcium phosphate samples were prepared by sol-gel routine, then examined by several tests, such as, Fourie transform infrared spectroscopy to study the deficiency of -OH, X-ray diffraction test to study the microstructure of the tricalcium phosphate with the rhombohedral structure in a hexagonal crystal system, differential scanning calorimetry and thermogravimetry tests to study thermal characteristics, scanning electron microscopy and energy dispersive spectroscopy to study the surface topography and to obtain the atomic ratio Ca/P ~1.5. Finally, the UV-vis test found the optical energy gap, Eg, from ~5.34 to ~5.41 eV for the sample calcined at 800 °C and Eg ~5.19 to ~5.21 eV at 1000 °C

Dampak Pandemi Covid-19 terhadap Tenaga Kerja Formal di Indonesia

Even though the informal labour still dominates Indonesia workforce, the trend of formal labour increases each year. BPS data shows that in 2015, the percentage of formal labor reached 42,25 percent. Then it increased to 44,28 percent in 2019. As a capital-intensive sector, formal sector supports economy of Indonesia, because it is relatively safe or less prone to shut down. However, the determination of the global pandemic status on March 11, 2020 due to Corona Virus Disease (Covid-19) has hit the world economy, including Indonesia. To suppress the spread of Covid-19, people are asked to work, study, or pray from home. This causes many companies suffer losses and even close their businesses, thus impacting workers. Based on data from the Ministry of Manpower 13 April 2020 as many as 1.2 million formal labour have been furloughed and 212.4 thousand have been laid off. This study aims to observe the trends of formal labour in Indonesia and the impact of Covid-19 on formal labour in Indonesia. This study uses secondary data obtained from various sources which are analyzed descriptively

Potensi Biji Labu Kuning sebagai Agen Fitoestrogen pada Wanita Post Menstrual

Osteoporosis and hypercholesterolemia are prevalent condition in menopausal women. The common therapy to prevent the estrogen degrading condition is Hormone Replacement Therapy (HRT). However, HRT possessed various risks. Curcubita pepo L. seed (pumpkin seed) contains lignan secoisolariciresinol and lariciresinol which exhibit estrogenic effect. The aim of this study is to determine the estrogenic effect of Ethanolic Extract of Pumpkin Seeds (EEPS) through in silico and in vivo study. In silico study were conducted by molecular docking of lignan which is secoisolariciresinol and lariciresinol with Estrogen Receptor (ERα and Erβ). In vivo study conducted by using ovariectomized Sprague dawley female rats as a model of postmenopausal women. Blood lipid profile, bone density, and uterine weight were assayed after thirty days. Molecular docking score of secoisolariciresinol and lariciresinol were similar to estradiol. In vivo study found that EEPS increase bone density and uterine weight percentage while also improve the blood profile. In conclusion, these result showed that EEPS is potential to be developed as an osteoporosis and hypercholesterolemia prevention agent
