Analysis of the Insulation Quality of 1000 kVA Distribution Transformer Oil Due to Aging at PT. Bambang Djaja Surabaya
Get PDFThe reliability of transformer insulation is a crucial factor in preventing damage that can lead to fatal accidents and serious disruptions in electrical systems. Aging insulation can cause performance degradation in transformers, necessitating a comprehensive evaluation to detect potential damage at an early stage. This research aims to evaluate the condition of transformer insulation using several testing methods, namely Breakdown Voltage (BDV) and Dissolved Gas Analysis (DGA). Among these methods, DGA is the main focus due to its ability to detect internal disturbances early, such as heat release, arcing, and overheating. Dissolved gas analysis in insulating oil provides critical information to detect anomalies, allowing preventive measures to be taken before the damage becomes more severe. In this study, testing data from both BDV and DGA methods were obtained through experiments and observations on transformers that have been in operation for a certain period. The obtained data were thoroughly analyzed and compared with international standards, such as IEEE and IEC, to identify potential failures, such as insulation degradation, overheating, or abnormal energy release. The analysis results show that combining several testing methods, particularly DGA, can provide accurate results in detecting potential damage at an early stage. This research makes an important contribution to transformer management, especially in the implementation of predictive maintenance, to enhance the safety, reliability, and operational efficiency of transformers
Foreshadowing and Its Results to Plot Twist in Lloyd F. Loux’s A Clever Catch
Get PDFThis article investigates how the plot twist in Lloyd F. Loux’s A Clever Catch is done through foreshadowing. The action of foreshadowing is to introduce subconscious clues to the audience without spoiling the result. Loux’s story is about a man who has an obsession with a thief woman and intends to catch her. At last, he succeeds in catching the thief and brings her before the magistrate, but then the magistrate does not punish her but gives best wishes to both of them. Through qualitative method and explorative approach, this paper underlines that the plot twist is preceded by the senses of law, starting from the thief, the accusation, the man as the detective, and the magistrate. At last, the punishment is not severe, but happy since all of the symbols eventually indicate a man who goes after a woman he loves. In conclusion, the foreshadowing in Loux’s story brings suspense and anxiety to the audience which then later presents a grateful happy ending as the plot twist

Diversity And Abundance Of Macrozoobentos And Pisces In The Mangrove Area Of Gresik District, Kebomas And Manyar Gresik Regency
Get PDFMangrove ecosystems play an important role in the life cycle of various types of fish, shrimp and crabs. Because the mangrove environment provides protection and nutrients in the form of organic matter that is included in the food chain. Some of the fauna that are commonly found in the Indonesian mangrove ecosystem area are fauna from the gastropod, crustacean, bivalve, polychaeta, and pisces classes. One of the biota that can be used as biological parameters in determining the conditions of a body of water is macrozoobentos. As organisms living in waters, macrozoobentos are very sensitive to changes in the quality of the water in which they live so that it will affect their composition and abundance. This research method is quantitative descriptive research by taking data in a survey. It uses a 1x1m measuring plot 100m long perpendicular to the coastline. The measurement method used to determine the environmental conditions of mangroves is the transect line method and sample plots (Tran-sect Line Plot). The diversity index value at research locations I and II is in the medium category, while in location III it is in the high category. Of the three stations, the uniformity index is stable close to 1. Result The dominance index value is that there is no type that dominates a body of water, this means that all individuals at the observation station have the same opportunity and maximally make the most of the resources in those waters. The pH results of water at station II and station III did not differ significantly, while at station I it differed significantly when compared to the results at stations II and III. The salinity results at station III differ significantly from station I and II because the location of the mangrove is the location of a sea estuary that makes the salt content of brackish water mixed with fresh water.
