Elektroplating adalah metode finisihing yang digunakan untuk menaikkan sifat dan tampilan dari logam, hal ini dikarenakan logam utama akan dilapisi oleh ion-ion logam jenis lain. Dengan adanya proses elektroplating dapat memberikan sebuah metode yang relatif mudah dan murah untuk menaikkan sifat dan tampilan dari logam. Prinsip dasar dari elektroplating adalah logam yang ada dibagian katoda akan melepaskan ion-ion untuk selanjutnya menempel pada logam yang dihubungkan dengan anoda. Proses ini akan berjalan secara terus menerus sampai dengan arus listrik yang dialirkan dimatikan. Pada penelitian ini dilakukan proses elektroplating dengan menggunakan aluminium 2024 sebagai logam utama dan nikel seabagai logam pelapis. Variasi dari waktu yang digunakan pada proses elektroplating adalah 20 menit, 30 menit, dan 40 menit. Setelah dilakukan proses elektroplating maka selanjutnya aluminium dilakukan uji kekerasan untuk mengetahui dampak dari variasi waktu proses elektroplating. Dari hasil pengujian kekerasan menggunakan metode Hardness Vickers maka spesimen dengan nilai tertinggi terdapat pada variasi waktu 20 menit dengan nilai 328,11 kgf/mm, sedangkan yang paling rendah terdapat pada variasi 40 menit dengan nilai 140.445 kgf/mm. Dari hasil foto mikro juga menunjukkan bekas indentor pada variasi 40 menit memiliki lubang terbesar sedangkan pada waktu 20 menit yang paling kecil. Sehingga semakin lama dari proses elektroplating akan menurunkan nilai kekerasan dari aluminium alloy 2024 yang dilapisi dengan nikel.

The rapid industrial growth and urbanization in Indonesia over the last two decades have resulted in a significant increase in air pollution, so it has caused a decrease in air quality. An air pollution inventory is needed to determine the level of air quality, emission sector, and the type of pollutant fuel. Air pollutant emission data were obtained from various sources, including Regional Emissions Inventory in Asia (REAS) V3.1, Database Emissions for Global Atmospheric Research (EDGAR) V4.3.2, and Community Emissions Data System (CEDS) V1.0. The data consists of 3 types of emitted pollutants (CO, NOX, and SO2) and two contributing factors (emission and fuel sectors). This study aims to compare data from the emission sources of the three air pollutants, determine the trend of changes in the emission of the three pollutants, and determine the main sectors and fuels that emit the three air pollutants. This research uses the literature study method to collect, visualize, and analyze data. The results showed that between 2005 and 2012, there was a downward trend in emissions in the industrial sector for CO, NOX, and SO2 gases, with the lowest point in August. This is because many industrial sectors have applied the principle of clean energy to reduce air pollution and create clean air. However, the transportation sector showed an increase in CO and NOX emissions and peaked in April and October. Furthermore, the SO2 emissions for the power generation sector fluctuated and peaked in July.

Sugar industry processes release large amounts of wastewater and pollution concentrations. This study focuses on environmental pollution produced by a cane sugar factory (Sampling Assalaya factory) with particular emphasis on the chemical properties of wastewater as an essential feature identifying water pollution in the study area. The study aims to analyze wastewater’s chemical features and disparity based on the Sudanese Standards and Metrology Organization (SSMO) standards. The systemic random sampling method collected twenty samples for each parameter (pH, Total Hardness, PO4, BOD, and COD). Analyses were conducted in the laboratory according to the standard methods for examining water and wastewater (USA). Results revealed significant variations in wastewater features at different sampling sites as pH values ranged between 4.55 to 8.39 and PO4 ranged between 0.097 ppm to 670 ppm in the selected sites. Results also pointed out that Total hardness ranged between 50ppm to 470ppm, BOD ranged between 15ppm to 390ppm, whereas the COD in 80% of the tested samples exceeded the SSMO standard (150ppm). The article concluded that these levels are highly exceeding the recommended level by SSMO. The leading causes of such alarming pollutant levels are related to the effluent of the Assalaya sugar factory in the study area. To reduce such effluent pollution levels, suggestions are made for the Assalaya cane sugar factory to treat its effluent by introducing appropriate technology and methods, such as anaerobic treatment. The Assalaya sugar factory ought to keep up with the transformation to green production as an integral part of its policy to achieve sustainability.

Let be a graph having vertex set , edge set , number of vertices | | , and number of edges | | . A super graceful labeling is a bijection function such that | | for every . A graph is called a super graceful graph if it admits a super graceful labeling. A tree is a tree obtained from a star on vertices by joining each vertex (one vertex if ) of degree 1 , , , to different new vertices . Super gracefulness of many classes of graphs, including special classes of trees, has been studied in the literature. In this paper we present a super graceful labeling of the tree .
