Abstract

This study was conducted with the primary goal of enhancing the octane number in Pertalite, a commonly used type of gasoline, through the addition of acetone as an additive. To achieve this objective, an experimental method involving the addition of various concentrations of acetone to Pertalite and measuring the resultant octane number using the Inductively Coupled Plasma (ICP) method was employed. Acetone, an organic compound from the ketone group, is known for its potential to increase the octane number in gasoline, which can subsequently affect engine performance and exhaust emissions. During the research, different concentrations of acetone were mixed into the fuel samples and their effectiveness in raising the octane number was measured. The results indicated a significant increase in the octane number of Pertalite with the addition of acetone. Further statistical analysis reinforced these findings, showing a significant correlation between increased acetone concentration and the enhancement of the octane number. This suggests that acetone can be considered an effective and economical additive for improving fuel quality. From these results, it can be concluded that acetone holds great potential as an economical additive that can significantly enhance fuel quality efficiently. These findings provide an important contribution to the fuel industry, particularly in the development of additives that can improve fuel performance while maintaining low production costs. It is hoped that these results will spur further research and practical applications in fuel formulation in the future.

Abstract

This study aims to analyse the use of animated videos in enhancing the learning creativity of primary school students. Using qualitative methods and a field study approach through observation, interviews, and document analysis of teachers and students in Grade IV at Rato State Primary School, it was found that animated videos are able to attract interest in learning, clarify understanding, and encourage students' imagination and creative ideas. Creativity is evident through original thinking, courage to experiment, and the creation of simple works. Success is influenced by teacher planning, selection of relevant content, and activities that stimulate creative thinking. It is concluded that animated videos have great potential as an innovative learning strategy. Further research is recommended using a quantitative approach and the development of interactive video models across subjects.

Abstract

PT XYZ sangat bergantung pada material casing sebagai komponen penting dalam kegiatan pengeboran, sehingga pengendalian persediaan menjadi krusial untuk mencegah kondisi stockout maupun overstock. Overstock meningkatkan biaya penyimpanan dan risiko kerusakan material, sedangkan stockout dapat menghentikan operasi pengeboran. Penelitian ini menggunakan data sekunder periode Januari–Desember 2024, meliputi catatan permintaan, purchase order, biaya pemesanan, dan biaya penyimpanan. Metode Economic Order Quantity (EOQ) diterapkan bersamaan dengan analisis ABC, safety stock, Reorder Point (ROP), serta kajian lead time. Pengolahan data dilakukan menggunakan Microsoft Excel untuk menentukan jumlah pemesanan optimal dan menghitung total biaya persediaan. Hasil penelitian menunjukkan fluktuasi permintaan pada lima jenis casing prioritas yang seluruhnya masuk kategori A dalam analisis ABC karena nilai penggunaan tahunannya yang tinggi. Total biaya persediaan perusahaan masih sangat besar akibat frekuensi pemesanan yang tidak efisien dan tingginya biaya penyimpanan. Perhitungan EOQ menunjukkan bahwa jumlah pemesanan optimal dapat menurunkan total biaya secara signifikan. Analisis safety stock dan ROP juga menegaskan perlunya penjadwalan pengadaan yang lebih akurat untuk menghindari risiko stockout. Pengendalian persediaan di PT XYZ dapat dioptimalkan melalui penerapan kebijakan pemesanan berbasis EOQ yang didukung safety stock, ROP, dan klasifikasi ABC. Implementasi metode ini meningkatkan efisiensi biaya sekaligus memastikan ketersediaan material casing secara berkelanjutan.

Abstract

This Community Service Program aims to enhance awareness and love for a clean environment through Qur’anic guidance assistance in RW. 5, Sibanteng Village, Leuwi Sadeng District, Bogor. The method used is Participatory Action Research (PAR) with approaches including Mapping, Transect Walk, Matrix Ranking, Timeline, and Trend and Change. The results show that public awareness of environmental cleanliness remains low, as indicated by the habit of dumping waste into rivers and the lack of waste management facilities. Through weekly Qur’anic study sessions, the community has begun to show positive behavioral changes regarding the importance of cleanliness as part of religious practice. This program provides tangible contributions in fostering a clean and environmentally friendly culture within religious communities.
