CHARACTERISTICS OF PYROLYSIS OIL BATCH POLYETHYLENE AND POLYSTHYRENE PLASTIC WASTE AT VARIOUS TEMPERATURES

Efforts are being carried out in order to utilize polyethylene (PE) and polystyrene (PS) plastic waste by converting them into fuel or oil. One technology that can be used is pyrolysis. This study aims to (1) determine the quantity and the characteristics of oil from the results of pyrolysis polyethylene (PE) and polystyrene (PS) plastic waste at various temperatures which include characteristics of physics (specific gravity, heating value, flash point, pour point, and kinematic viscosity) and chemical characteristics (composition compounds in oil), (2) determine the optimal conditions of process pyrolysis related to the quality and quantity of oil by pyrolysis, and (3) determine the potential treatment of PE and PS plastic waste by pyrolysis method.The materials used in this study were the type of polyethylene (plastic bags) and polystyrene/styrofoam (for fruits or vegetables) plastic waste. The selected temperature variations are T = 400oC, 450oC, and 500oC. Pyrolysis oil was weighed and measured its volume to obtain v/wo and yield.The results showed that the quantity of pyrolysis oil from polyethylene (PE) plastic waste at temperatures of 400, 450, and 500oC based on v/wo (ml/g) respectively were 0.3429 ml/g; 0.5129 ml/g; and 0.199 ml/g while the results of polystyrene (PS) plastic waste at temperatures of 400, 450, and 500oC respectively were 0.89 ml/g; 0.905 ml/g; and 0.915 ml/g. The results of pyrolysis oil based on yield of polyethylene (PE) plastic waste at temperatures of 400, 450, and 500oC respectively were 33.33 wt%; 38.61 wt%; and 15.55 wt% while polystyrene (PS) plastic waste at temperatures of 400, 450, and 500oC respectively were 80.94 wt%; 79.79 wt%; and 80.14 wt%. While the characteristics shown by the results of pyrolysis oil from PE plastic with a temperature of 400oC were closer to kerosene while at temperatures of 450 and 500oC were closer to the characteristics of diesel fuel. As for pyrolysis oil results of PS plastic with temperatures of 400, 450, and 500oC were closer to the characteristics of gasoline. Optimal conditions of pyrolysis oil related to the quantity of pyrolysis of PE plastic at a temperature of 450oC was obtained when the highest of v/wo and yield respectively were 0.5129 ml/g and 38.16 wt%, while for the pyrolysis of PS did not have any optimal conditions. For, oil produced was relatively constant despite the increasing temperatures. Based on technical analysis, handling PE and PS plastic waste using pyrolysis methods provides benefits to society making it feasible to do

Pengaruh modifikasi lift camshaft dengan bahan bakar pertalite dan pertamax terhadap kinerja mesin 110 cc

Modification of the camshaft lift with pertalite and pertamax fuel has been carried out. This study aims to determine the effect on engine performance, namely a change in lift of 1 mm is able to maximize performance to be better than the standard. In this study using a 110cc motorcycle engine with pertalite and pertamax fuels to show a comparison of modifications to the standard. The results obtained are the modified 1mm lift camshaft with Pertamax fuel produces maximum power and torque compared to the standard camshaft, with values of 13.33 hp and 13.38 Nm, respectively. The highest increase in power and torque on pertalite fuel is found at 7000 rpm which can increase performance by 7.4% and 7.2%, respectively, from the standard camshaft. Meanwhile, the highest increase in power on Pertamax fuel was obtained at 5500 rpm rotation with a value of 12.1% while the highest torque increase in Pertamax fuel was obtained at 8000 rpm rotation with a value of 11.9%

Peningkatan Jumlah Produksi Kerajinan Anyaman Tas Dengan Alat Pemotong Dan Pengukur Tali Pengepak

ABSTRAK        Tujuan dari kegiatan ini adalah: 1) Meningkatkan kuantitas dan kualitas produk kerajinan anyaman tas dari limbah tali pengepak di Kabupaten Jember 2) Meningkatkan kemampuan SDM pelaku usaha dan ibu-ibu di lingkungan sekitar usaha. Metode yang digunakan adalah diskusi dan pengumpulan referensi untuk mendesain dan membuat alat pemotong dan pengukur tali plastik, pemberian pelatihan manajemen usaha dan sistem pengelolaan keuangan dan pemberian pelatihan menganyam.
