Porous hydroxyapatite has high biocompatibility, osteoconductivity, and resorbable properties. One technique for making porous hydroxyapatite is the starch consolidation method. The purpose of this study was to carry out an in-vitro test of porous ceramics formed by the starch consolidation method using Simulated Body Fluid (SBF) solution and to determine the effect of starch mass addition and …
One of potential renewable energy source is biodiesel. Crude palm oil (CPO) is used as a raw material. Biodiesel synthesis is influenced by several factors, namely the type of catalyst, catalyst weight and the mole ratio of oil: methanol. The catalyst used is heterogeneous solid base catalysts. The purpose of this study is to produce biodiesel from CPO (crude palm oil) using CaO/ fly ash cataly…
Microalgae is one of the potential alternative energy sources to be develop as biodiesel raw material. Biomass productivity and lipid content are important parameters affecting the feasibility of using microalgae for biodiesel production. Light and nutrition are important factors that influence the growth and lipid content of microalgae. This study aims to determine the effect of photoperiods a…
In this study the cultivation of microalgae using peat water and the addition of NaNO3 was 1 g / l; 1.25 g / l and 1.5 g / l. Microalgae biomass produced from the cultivation process is used as animal feed. The kinetics of the Logistic model and the Monod model are used to predict the growth of microalgae in the cultivation process. The results showed that the addition of 1.5 g / l NaNO¬3 prod…
The exploitation excessive peat fires resulted in the dry season. This fire can be minimized by utilizing the potential of groundwater on peatlands. The potential of groundwater can be determined by pumpingtestso that it can be known the aquifer characteristics in the form of storage capacity (storativity), transmisivity coefficient, and decrease in groundwater level in the observation well. Pu…

Fire is a condition of a location that experiences excessive drought or no water that causes drought. Peatlands in Indonesia are 14.9 million hectares, covering around 50% of the world's tropical peat. Riau Province which has the largest area of peatlands in Indonesia is 55.3%. Unproductive peatlands in Indonesia are reported to be 4.2 million hectares. Under natural conditions, peat is a type …
Increasing the concentration of carbon in the atmosphere becomes one of the serious environmental problems that can affect the Earth's life system. Increased concentration occurs more due to the disruption of energy balance between the land and the atmosphere. Peat land clearing into a palm oil plantation land is known to cause the loss of carbon content such as carbon dioxide gas (CO2) to the …
