Latent Dirichlet Allocation has been developed as topic-based method which uses reasoning to determine the topics of a document. There are many methods of reasoning used for Latent Dirichlet Allocation, including the Gibbs Sampling and Mean Variational Inference, the most widely used in research. However, there have not been many studies that discuss the implementation of these methods on the Indonesian...
Tiga Nusa is a region consist of three small islands: Nusa Penida, Nusa Lembongan, and Nusa Ceningan, that located southeast of Bali Island. Those three small islands have many magnificent diving sports that are famous among divers all over the world. Therefore, this region becomes one of tourist attraction initiate rapid development. Energy demand in this region is increasing significantly. The power...
Microhydro is one among various renewable technologies that can be developed to generate clean and sustainable electricity in Bali. As a result, the local utility company has planned to develop several mini-hydro in Bali for the next five years with total capacity of 30 megawatt. Two micro hydro plants each of 25 kW and 20 kW capacity are currently in operation to generate electricity for villagers...
Nusa Lembongan is a small tourist destination island in Bali that is operate mostly during daytime. The photovoltaic solar system is designed to supply 30% of the energy needed it come to the photovoltaic solar system capacity installed 21,694.8 Watt peak that consist of 144 panels . The photovoltaic solar system will hybrid with the utility supply. The economic cost analysis result that Life Cycle...
This paper presents results of an integrated condition monitoring of a power transformer. The main concern is that the equipment produces unusual vibration and noise, which is significantly higher than those initiated by similar type of transformers operated in the region. Several condition monitoring techniques were applied to the transformer including vibration and partial discharge measurements...
Insulator strings in transmission system are subjected to direct weather during its service. The withstandability to the weather is different for each insulator in a string. The withstand-ability of an insulator drops due to defect on the surface and or internal the insulator. Defect on the surface can be observed by using an visual detector such as daycor corona meter, however the internal defect...
Composite insulator are widely used as an outdoor insulator now days. Deterioation due to severe weather and vandalism are usually undetectable. There are many techniques have been introduced in order to detect the insulator condition, one of the technique is introduce here by using partial discharge analysis. The work has been done by examining the PD patterns and behaviour of three different insulator...
