Abstract

Penelitian ini dilakukan untuk membandingkan sifat mekanik hasil peleburan alumunium kaleng bekas berbahan bakar minyak pelumas bekas, baik tanpa mengalami perlakuan panas maupun dengan perlakuan panas anealling. Perlakuan panas anealling dilakukan menggunakan 2 metode yaitu aneallingmenggunakan dapur listrik dan anealling menggunakan lemari pemanas yang dipasang pada tungku krusibel dengan temperatur 343 °C dan holding time selama 1 jam. Spesimen hasil peleburan dilakukan uji komposisi kimia yang bertujuan untuk mengetahui kandungan-kandungan yang terdapat di dalam spesimen tersebut. Pada pengujian kekerasan tetjadi penurunan nilai BHN untuk speimen yang diberi perlakuan panas anealling dapur listrik dan lemari pemanas masing-masing sebesar 21,2% dan 31,67%. Selain itu terjadi juga penurunan nilai tegangan untuk spesimen pengujian tarik terhadap nilai ?u sebesar 23.9% dan 9.5% dan ?f sebesar 16,34% dan 5,17% sedangkan pertambahan panjangnya naik menjadi 1,3% dan 1,467%. Spesimen yang diberi perlakuan panas anealling dapur listrik dan lemari pemanas mengalami peingkatan nilai impak sebesar 25,04% dan 30,1%. Perlakuan panas anealling yang dilakukan bertujuan untuk menghilangkan tegangan sisa yang terjadi akibat proses peleburan agar dapat mengubah sifat mekanik spesimen tersebut

Abstract

Smelting aluminum scrap in a small capacity can be done on a simple furnace crucible. As fuel furnaces used type of semi-anthracite coal briquettes, bituminous and sub-bituminous from Tanjung Enim which has been through the washing process by agglomeration method using water-oil palm. Calorific value, the contents of water and hydrogen calculated in the energy balance. Aluminum scrap smelted at a temperature 1023oK. Furnace by coal briquette which has a 23.38% efficiency,, crucible can melt 50 kg of aluminum scrap by 6.47 kg of briquettes for 1 hour 46 minutes.Keywords:coal briquette, coal aglomeration, aluminum scrap, crusible furnace

Abstract

From technological developments that are so increasingly competitive and increasingly needed in people's lives for their daily needs on social media as is often used by the community, namely Twitter, Facebook, Instagram, Youtube, WhatsApp and other social media. But the general public does not know that the data sent is stored on a central server so that other people can use the data to commit crimes such as taking identities so that it can be used as a tool to act to spread information that is not infallible for other crimes that can harm many people. Therefore, the researcher developed an investigative framework in social media as data collection using the System Development Life Cycle (SDLC) method. In developing this data collection framework, researchers used the Maltego tool as a means of proving the identity of the perpetrator. The designed framework will produce five stages, namely planning, analysis, design, maintenance, and implementation. The digital evidence that will be obtained from these tools includes twitter accounts, email addresses, phone numbers, DNS, websites and social media.

Abstract

The application of machine learning in computing has become one of the most significant developments in modern technology. This study examines a range of use cases from various sectors, including healthcare, finance and transport, which demonstrate how machine learning can improve the efficiency, accuracy and capabilities of computer systems. Through case study analysis, it is shown that machine learning is capable of automating complex tasks and providing deep insights. However, the implementation of this technology also faces a number of challenges, such as the need for high-quality data, model interpretability issues, and high computational costs. Furthermore, there are ethical and legal issues to be considered, especially in relation to privacy and potential bias in the models. This research highlights the importance of a careful approach and appropriate strategies to overcome these barriers, in order to fully utilise the potential of machine learning while minimising the risks involved.

Abstract

The objective of this study is to assess the effectiveness of the Mubasyarah method in enhancing the Arabic language proficiency among seventh-grade students at Harsalakum Bengkulu Secondary School. The research employs a quasi-experimental quantitative approach. The target population consists of seventh-grade students at Harsalkam Bengkulu Secondary School, with cluster sampling used to select two groups: Class V-A (25 students) as the experimental group and Class VC-C (26 students) as the control group. Data collection involves pretest, treatment, and posttest phases. Analysis techniques include normality tests, homogeneity tests, and t-tests. Data analysis is conducted using SPSS version 26, and the t-test results show a significance value of  0.000, which is less than the threshold of 0.05 (0.000 < 0.05). Thus, the null hypothesis (Ho) is rejected, and the alternative hypothesis (Ha) is accepted. Consequently, it can be concluded that the Mubasyarah method effectively enhances the language fluency of seventh-grade students at Harsalakum Bengkulu Secondary School.
