Abstract

Cadangan batubara sebagai sumber energi tidak terbarukan semakin menipis. Untuk mengurangi laju pemakaian bahan bakar batubara maka dilakukan penelitian blending batubara dengan sumber energi terbarukan berupa biomassa seperti tongkol jagung. Dalam penelitian ini diamati pengaruh rasio tongkol jagung terhadap batubara untuk mendapatkan kualitas campuran bahan bakar terbaik yang memenuhi syarat untuk diaplikasikan pada industri dan pembangkit listrik. Parameter kualitas campuran batubara dan tongkol jagung yang diamati adalah nilai kalor dan kadar sulfur. Bahan bakar batubara yang digunakan dalam penelitian ini memiliki nilai kalor  8403 cal/gram dan kadar sulfur 0.71%. Sedangkan tongkol jagung memiliki nilai kalor 3409.64 cal/gram dan kadar sulfur 0.14%. Dari penelitian ini diperoleh pencampuran terbaik dengan rasio tongkol jagung terhadap batubara sebesar 75% yang memberikan nilai kalor 4741.54 cal/gram dan kadar sulfur 0.26%. Kualitas pencampuran batubara dan tongkol jagung ini memenuhi syarat untuk diaplikasikan pada Pembangkit Listrik Tenaga Uap (PLTU). Pemanfaatan hasil pencampuran bahan bakar ini dapat mengurangi laju pemakaian batubara sebanyak 75%.

Abstract

Fe₂O₃ has many functions, including as a pigment and as a semi-conductor material. The use of this material depends on its characteristics. In this study, the characterization of Fe₂O₃ nanoparticles produced from green synthesis was carried out. Dengen fruit extract was used as a chelating agent with iron sand raw material from the Pajallesang River, Palopo City. The synthesis was carried out using the sol-gel method at pH 4.7. The gel sample was calcined at temperatures of 600°C, 700°C, and 800°C, after which it was characterized using XRD and XRF. The average crystallite size of Fe₂O₃ particles in iron sand and after being synthesized at temperatures of 600°C, 700°C, and 800°C were respectively 40.09 nm, 36.67 nm, 31.46 nm, and 69.04 nm. The increase in calcination temperature affects the Fe₂O₃ content, where the higher the temperature used, the lower the Fe₂O₃ content obtained. The Fe₂O₃ content in iron sand and after synthesis at temperatures of 600°C, 700°C, and 800°C were respectively 70.4%, 91.04%, 90.01%, and 88.82%

Abstract

Manganese is one of the mineral products of mining, especially those found in Indonesia, such as in the Paludda area of Barru Regency, South Sulawesi. Manganese ore is known as raw material for steel industry, battery industry and chemical industry. This research was conducted at the Mining Engineering Study Program's Materials Processing Laboratory. The purpose of this study was to determine the percentage increase in manganese ore content after the concentration process, determining the recovery of manganese ore against variations in grain size using a shaking table. The analysis used in this research includes shaking table equipment, XRF analysis and also XRD analysis, from this processing will be obtained Mn content. The results of this study show shaking table separation using operating variables with an initial sample weight of 500 grams with levels in the initial sample of MnO of 33.58%, in concentrate -65 of 26.60%, concentrate -100 of 25.93%, concentrate -150 of 25.46%, concentrate -200 of 26.93%, in tailings -65 of 24.17%, tailings -100 of 23.79%, tailings -150 of 22.79% and tailings -200 of 22.60. Therefore, the results of the study can be concluded that the shaking table operation obtained the optimal concentrate and tailings in the -150 MnO concentrate with a recovery of 23.65%, then the -100 MnO tailings with a recovery of 38.68%

Abstract

The increasing problem of plastic waste poses a serious environmental challenge and requires environmentally friendly and educational solutions. This community service activity aims to introduce the design and implementation of a plastic waste processing device that converts plastic into fuel oil (BBM) using the pyrolysis method, targeting students at UPT SMA Negeri 4 Parepare. The program was implemented through counseling sessions, interactive discussions, and demonstrations of the pyrolysis device, adjusted to the students’ level of understanding. Evaluation was conducted using pre- and post-tests, participant satisfaction surveys, and direct observation. The results showed that 84% of students demonstrated improved understanding of the material, and participation and satisfaction rates exceeded 90%. These findings indicate that the activity not only succeeded in raising students’ environmental awareness but also provided them with practical knowledge about simple technology for plastic waste management.
