Abstract

The problem of plastic waste is a global problem that is increasingly urgent to be resolved, including in Indonesia, in the city of Ambon. Especially at the Benteng Karang Integrated Waste Treatment Plant (IPST), plastic waste is one of the most dominant and difficult types of waste to handle. Plastic waste that is not managed properly can accumulate and cause various environmental problems, such as land and marine pollution, which ultimately damages the ecosystem and threatens the life of marine biota and the environment. Shredding plastic waste provides a variety of significant benefits, including reducing the volume of waste so that it is easier to transport and store, and making it easier to recycle. Shredded plastic pieces require less energy to melt and are easily reshaped compared to whole bottles, saving energy in the recycling process. Researchers took data directly at the research location regarding plastic waste at the Benteng Karang Integrated Waste Treatment Plant (IPST), Ambon city, data on the volume of waste entering the Integrated Waste Treatment Plant (IPST) per month in 2023-2024 in Ambon city. In one month, according to the data obtained, 5.6 tons of plastic waste. So in one day get 18.7 kilograms. The motor control system uses the DOL system. The experiment we got from chopping 1.5 kilograms of plastic waste took 43 minutes 15 seconds Keywords: Shredding plastic waste

Abstract

Analysis of the impact of transformer overload on the sulamadaha refeeddersa of the gt-solba ternate feeder north maluku, An overload transformer occurs in one of the distribution transformers at pt. Pln (persero) up3 ternate ulp ternate, namely the gt-solba distribution transformer in sulamadaha with a loading amount of 100,64% exceeding the standard set by spln which is 80%. This study aims to find a way to overcome the problem of overload in the gt-solba distribution transformer in sulang suladaha and also to get the load on the gt-solba distribution transformer before and after transferring the transformer load. Conducting this research using data collection methods by collecting data at ulp ternate, interviewing field supervisors and studying literature that supports problem solving in the gt-solba transformer. In solving. Therefore, in overcoming the problem of overload on the gt-solba transformer, improvements are made by looking at these conditions, one of which is by shifting the transformer load or switching the transformer power with the same capacity of 160 kva as the previous transformer of 160 kva. From the results of the load transfer, it was obtained that the loading results obtained the percentage value of the transformer loading before the transformer load was transferred, namely 100,64% and after the transformer load was transferred, namely 43,2%, so that it decreased by 56,8%. Which means that transformer load switching is one of the methods that can be used to overcome overload. Keywords: GT-SOLBA Transformer, Overloading, Sulamadaha Substation
