Alat ini telah meningkatkan kuantitas produk yang dihasilkan hingga mencapai 3 kali lipat. Selain itu, juga terjadi peningkatan kualitas dari produk anyaman tas yaitu tas menjadi lebih rapi karena ukuran tali yang seragam. Hasil luaran yang lainnya adalah adanya peningkatan kemampuan SDM pelaku usaha dan ibu-ibu di lingkungan sekitar usaha yang dengan sebelumnya hanya memiliki keterampilan mengayam tali pengepak menjadi mampu menganyam kerajinan anyamanbaru dengan bahan yang lain seperti menganyam tempat buah dari pitrit dan adanya tambahan jenis /model baru dari bentuk tas anyaman yang sudah ada.Kata Kunci: Tali Pengepak, Alat Pemotong dan Pengukur, Tas Anyaman ABSTRACT The direction of this program are: 1) Increasing the quantity and quality of handicraft bag products with matter of waste plastic packing strap in Jember, 2) Improving human resource capacity of agents and mothers in business environment. The method used are discussion and accumulation the reference to design and cause the cutting device and plastic strap gauge, a business management training and financial management system for agents and weave training. The result in this program is cutting device and plastic packing strap gauge. The device are consists of 3 components, are cutter knife, roller, and buffer. The cutting device consists of 2 knifes which are connected to static work so it can be used to determine the desired length of the strap. The length of the knifes is 40 cm with a static length is 130 cm. Roller is made of iron form of cylinder with diameter size of inner is 15 cm and length is 26 cm. Buffer 40 cm of height as a cutting device pedestal. Result of piece a plastic packing strap is can 10 pieces of strings with a uniform size in one to cut. The device has increased the quantity of products produced up to 3 times. In addition, there is also an increase in the quality of woven bag products that becomes more tidy because uniform size of strap.The other outcome is to improvement of human resource capacity the business agents and the mothers in the environment around the business who previously only have the abilityto weave the plastic packing straps to be able to weave new woven crafts with other materials such as weed the fruit of the pitrit and the addition of new types or models of the form of woven bags that have been there before.Keywords: Plastic Packing Strap, Cutting Device And Gauge, Handicraft Bag
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.
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%.
Kebutuhan energi di Indonesia saat ini masih didominasi oleh energi yang berbasis bahan bakar fossil, seperti minyak bumi dan batu bara. Kerugian dari bahan bakar fosil adalah sifatnya yang tidak ramah lingkungan. Air adalah sumber energi alternatif yang dapat menggantikan sumber energi berbasis fosil dan merupakan energi terbarukan. Turbin Archimedes Screw merupakan turbin yang cocok digunakan di Indonesia yang mempunyai aliran sungai dengan head rendah. Penelitian ini menggunakan metode eksperimen, yaitu merancang dan membuat turbin Archimedes Screw. Hasil pengujian selama 180 menit dari ketiga model turbin Archimedes screw, yaitu tipe ulir 1 menghasilkan tegangan 2,83 volt, tipe ulir 2 menghasilkan tegangan 3,16 volt dan tipe ulir 3 menghasilkan tegangan 2,49 volt. Tipe ulir 2 yang bisa menghasilkan tegangan lebih besar selama 180 menit yaitu 3,16 volt.
