Heavy metal such as chromium (Cr) is waste from electroplating has negative impact to organism because it’s toxic, hard to degrade, and accumulates in the body of exposed organism. Utilization of algae biomass can be an alternative solution to environmental pollution problems due to heavy metals, because it has an active site and pores on the surface so it can be used in biosorption process, …
Chitin is natural polymer which used in biomedic sector mainly for injury healing, suture and dietery because chitin has antibacterial, antifungal and antiviral properties. Chitin content in natural material can be isolated using deproteinasi and demineralization process. This research objection is to determine demineralization reaction kinetics in chitin isolation with temperature and shrimp s…
Waste has become a difficult problem to overcome worldwide where plastic consumes 40% of the waste. basically plastic is used as a wrapping tool. because the price is cheap, airtight and resistant to changes in plastic temperature so favored by the community while recycling technology is still expensive and the plastic is difficult to be deciphered by bacteria so that plastic waste accumulates.…
Used oil is used cooking oil that is generally not used for cooking or frying. The use of used cooking oil is very dangerous because it can cause various diseases, then the utilization of used cooking oil by way of clarified again for the manufacture of transparent soap. Transparent soap is bar soap with transparent or translucent appearance. In this study, the use of wood charcoal on refining …

Briquettes are biomass-based alternative energy sources. Biomass used in this study is cow dung. The purpose of this research is to utilize cow dung waste as raw material of briquettes, study the effect of using and without using adhesive to briquette’s characteristics and to determine the best briquette composition according to the national quality standard 01-6235-2000. The treatment of…
Power transformer plays a very important role in the electric transmission system to convert the voltage level of the system. An abnormal operation of power transformer can decrease its reliability. The most common cause of abnormal operation in power transformer is oil damage. Markov method is applied using Dissolved Gas Analysis (DGA) test from transformer oil to determine transformer’s ins…
Distribution Network is one of the parts in a power system that has an important role because it deals directly with users, especially the users of medium and low voltage level. Therefore it needs a protection system against abnormal condition to maintain the reliability of the system. The protective equipment analyzed in this article is the overcurrent relay (OCR) and ground fault relay (GFR).…
Based on wind speed data from Meteorology and Geophysics Agency, Indonesia has an average wind speed of about 3-6 m / s. Wind speed can be categorized at low wind speed. So the power station needs a low-speed generator. One solution found from this problem is the development of low speed power plant technology. The wind power plant has an important component of which is a generator which is an …
The increasing need for energy and the depletion of petroleum reserves forces people to seek alternative energy sources. The availability of non – renewables energy sources in the form of fossil fuels is one of the causes of global energy crisis. This phenomenon also affects the global electrical energy sector that is heading for critical threshold because the fulfillment of electrical energy…
Currently the increasing in electricity bill become hot topic in Indonesia society. The increasing of electricity bills is due to the uncontrolled usage of home appliances. In addition, the uncontrolled usage of appliance will also cause a fire. In this paper, control systems and monitoring of home appliances are designed to provide a solution. This design system is expected comply to Internet …
a networker's must have techniques or methods that are network management, so that the network can be made according to need. Network management recommended by Cisco is the Cisco Lifecycle Service Approach (CLSA) method, which manages the network until the redesign stages without changing the direction of the project's objectives. The purpose of making VPN network modeling is to see the effect …
In this research, study the effect of lnterference on both unicast and multicast d2d communication network using SimuLTE software, analyze the effect of interference to Device-To-Device (D2D) communication, with setting simulation parameters such as packet size, bandwidth, simulation time, distance and number of users. D2D communications work on the same cell with fixed transmission power. The …
Laying a WI-FI system that is required to optimize the received power level from the transmitter to receiver. Characteristic of the most influential in determining the performance of a WI-FI system is the power level value. This value can be used to determine the coverage are of a transmitter. The Genetic Algorithm is chosen because according to various references, it is considered a suitable a…
Early warning system is one of the technology to detect land fires by utilizing a network of wireless sensors. Constant data transmission by the sensor nodes consumes a large amount of energy on the nodes’ sides that could affect the battery’s longevity. This research is done to discover the amount of power consumption and battery longevity during fire emergencies, and during non-emergency …
