Abstract

 Analisa pengaruh berat roda daya (Flywheel) sangatlah berguna dalam dunia otomotif pada kendaraan roda empat khususnya mesin 7k. Dalam dunia otomotif kita dapat mengetahui kecepatan dan percepatan suatu kendaraan. Tujuan penelitian ini untuk mengetahui perubahan kecepatan kendaraan akibat adanya   perubahan berat roda daya dan mengetahui perubahan percepatan kendaraan akibat adanya perubahan berat roda daya dengan berat yang tertentu.Dari hasil perhitungan  analisis  berat roda daya 95,06 kg dengan putaran maksimum 2800 rpm, maka kecepatan kendaraan yang dihasilkan sebesar (V) 64.87 km/jam dan pada saat dimensi berat roda daya mengalami pengurangan berat hingga 86,24 kg menghasilkan putaran mesin 2939,23 rpm dan menyebabkan naiknya kecepatan kendaraan (V) 68,05 km/jam dan percepatan kendaraan Pemakaian roda daya standar dengan berat 95,06 kg dengan putaran maksimum mesin 2800 rpm kendaraan mengalami percepatan 13,161 m/s² dan pada saat dimensi berat roda daya mengalami pengurangan berat hingga 86,24 kg dengan menghasilkan putaran maksimum 2939,23 rpm kendaraan mengalami percepatan 13,246  m/s. Kata Kunci: Pengaruh, flywheel , akselerasi, mesin 7k.

Abstract

Penukar  panas sangat luas dipakai dalam dunia serti,pembangkit listrik, kilang minyak, pabrik kimia maupun petrokimia , industri gas alam, refrigerasi, dan lain sebagainya . Salah satu contoh dari alat penukar panas ayng terdapat pada industri pupuk PT.Pupuk Kalimantan Timur adalah Lean Solution Cooler 1-E-303. Kajian dalam tulisan ini berisi gambaran tentang hasil analisis pengaruh perubahan material tube  dari carbon stell menjadi stainless stell 304 terhadap perpindahan panas, jatuh tekan, diameter dalam shell, jumlah tube, dll  Dari hasil analisa perhitungan diketahui bahwa terjadi penurunan nilai perpindahan kalor yang terjadi sebesar 2001.76 W/K – 1950.78 W/K (sisi tube) dan 5707.46 W/K-5256.5 W/K (sisi shell), jatuh tekan sebesar 2.35 psi – 2.26 psi (sisi tube) dan 1.19 psi – 0.98 psi (sisi shell), dan kenaikan pada diameter dalam shell sebesar 954 mm – 999 mm, dan jumlah tube dari 1183 buah -1300 buah .Kata Kunci : Alat penukar kalor, koefisien perpindahan panas, jatuh tekan, & jumlah tube.

Abstract

Plastic waste is a type of inorganic waste that is difficult to decompose in soil and water. Plastic waste is usually only piled up and disposed of, causing various kinds of negative impacts. One of the efforts to tackle plastic waste in Bontang City is to create a tool that can convert plastic waste into fuel oil. The purpose of this community service is to provide an understanding to the community (students) regarding the dangers of plastic waste to the environment and to provide knowledge to the public about how to process plastic waste into fuel oil using practical and inexpensive pyrolysis technology. The method of implementing this community service activity is in the form of counseling and training. The results of this community service received a very good response from students and teachers. This response can be seen from the enthusiasm of the participants when carrying out the practice of processing plastic waste into fuel oil. The conclusion of this community service has a very positive impact on the processing of plastic waste into fuel oil and changes the habits of the Bontang people, which initially only disposed of plastic waste, then utilized it so that it had economic value.
