ABSTRACT Indonesia is the largest palm oil producer in the world. One of the by-products of palm oil processing plants is POME which is liquid waste. This waste is quite large and can be converted into biogas which can then be used as a source of electrical energy. Utilization of palm oil waste as a source of biogas energy is an alternative effort to generate electricity. In this study, the au…
ABSTRACT Concrete is a mixture consisting of Portland cement or other hydraulic cement, fine aggregate, coarse aggregate and water, with or without additives. Along with the addition of age, the concrete will harden and will reach the design strength (fc') at the age of 28 days. One of the factors that affect the compressive strength of concrete in cylindrical concrete is the influence of the …

One of the current online transportation services is grab, grab is a transportation service provider that was present in Indonesia in 2012 providing GrabCar and GrabBike. This…
ABSTRACT The sun is an unlimited source of energy and can be utilized, one of the uses of solar energy is to make electricity using solar photovoltaic as a medium for converting energy, the placement of solar photovoltaic is generally on the ground (ground mounted) but there are also floating placements, and also rooftops. Based on its placement, this study will discuss ground mounted solar ph…
ABSTRACT Radio Over Fiber (ROF) technology is a technology that combines fiber access networks with wireless systems where ROF uses fiber optic cables as an intermediary medium to obtain greater transmission speeds compared to direct transmission. Optical signal modulation can be transmitted in 2 ways, namely by direct optical modulation and external optical modulation. In this study ROF was d…
ABSTRACT Utilization of solar power through photovoltaic conversion has been widely applied as an alternative energy source because the source of energy is very large and the time is long. The implementation of its utilization can be done in open space, but it requires a large area of land to overcome these obstacles. The implementation of the SPV installation can be done by installing the SPV…
