Abstract

The increasing usage of plastic is proportional to the amount of plastic waste today. The plastic usage makes the human live easier especially for packaging purposes. However, it also has a negative impact to the environment. This is due to it cannot easily decompose. Therefore, it can reduce the level of soil fertility. Besides plastic, lubricant waste from motor vehicles can induce an environmental problem as well since it is categorized of hazardous material (B3) waste. Currently, the use of plastic waste has been widely carried out by correlating into liquid fuel through thermal cracking or pyrolysis treatment. It produces liquid and it can be used as an alternative liquid fuel. This study uses the co-pyrolysis method for treating the used plastic waste with used lubricants. The composition ratios used are 10:0, 10:2, 10:4, 10:6, and 10:8. The highest acquisition of liquid products was in the composition ratio of 10:6 as much as 24.67% with a calorific value of 11015.33 cal/g. Then the highest calorific, density, and viscosity values were obtained, namely at the 10:8 composition ratio of 11061.67 cal/g, 0.8906 g/mL, and 0.927 cSt. It was concluded that the mixing of used lubricants in the co-pyrolysis of LDPE plastic waste was able to increase the calorific value of the liquid product produced.

Abstract

Lithium batteries play a critical role in modern technological applications, including electric vehicles and portable electronic devices. Ensuring accurate estimation of their remaining useful life is essential to improve system efficiency and reliability. This study focuses on predicting the remaining useful life of lithium batteries using advanced regression methods. Data were collected from lithium battery charge-discharge cycles, encompassing key operational parameters such as voltage, current, and temperature. The analysis employed several regression models, including linear regression, lasso regression, and Ridge regression, to identify relationships between these parameters and battery life. The models were evaluated based on estimation accuracy, with Root Mean Square Error (RMSE) as the primary performance metric. The findings demonstrate that regression methods can effectively capture non-linear relationships between input variables and the remaining useful life, with lasso and Ridge regression showing superior performance in reducing prediction errors. These results underscore the potential of regression-based approaches in providing robust and reliable estimations of battery life. The conclusions highlight the importance of these models for developing predictive battery management systems, which can optimize battery performance and extend their operational lifespan across various applications. This research establishes a solid foundation for future studies on intelligent battery health monitoring and management.

Abstract

Pada PLTP-X sering mengalami permasalahan sering trip/manual shut down pada diesel engine yang mensuplai energi listrik untuk penerangan operasional dan pompa incjetion ke sumur. Permasalahan tersebut di akibatkan oleh tersumbatnya sistem penyaring bahan bakar B30, karena terbentuknya gelling/deposit pada kondisi malam hari pada suhu rendah 14-17°C di site PLTP-X. B30 di pakai karena,di wajibkan oleh Peraturan Menteri Energi dan Sumber Daya Mineral (ESDM) tahun 2020 tentang Penyediaan, Pemanfaatan dan Tata Niaga Bahan Bakar Nabati (Biofuel) sebagai Bahan Bakar Lain. Untuk itu diperlukan cara mengurangi pembentukan gelling/deposit agar permasalahan penyumbatan penyaring bahan bakar dapat di tanggulangi serta bahan bakar B30 dapat di pakai pada suhu rendah 14-17°C di site PLTP-X. Metode penelitan yang akan di pakai adalah dengan cara eskperimental yaitu memvariasikan penambahan zat aditif komersil pada bahan bakar B30 0%;,1,6%;,3,3%;, dan 5%. Hasilnya menunjukkan dengan penambahan aditif komersil dapat mengurangi pembentukan deposit bahan bakar B30 pada suhu rendah 14-17°C dengan menurunkan nilai propertis densitas  dari 880 kg/m3 menjadi 878 kg/m3, viskositas 8,8 mm2/s menjadi 5,3 mm2/s, menaikkan titik tuang awal dari 18°C menjadi 15°C dan nilai kalori 10198 cal/kg menjadi 10644 cal/kg.
