Abstract

The objective of this study was to determine the influence of alkali treatment on the flexural strength and failure mode of jute fiber waste/polyester composite materials. The materials being used in this research werewaste of jute fibers, polyester resin, where as NaOH and aquades were utilised for alcali treatment. Prior to being embedded into polyester resin to produce composite boards employing press printing techniques (press mold), the fiber was alkalitreated for 0, 2, 4 and 6 hours by soaking into a 28% volume NaOH content solution. Flexural test was carried out in accorcance with the ASTM D790 standard, and macrographs of selected fracture surfaces of the specimens were capturedfor analysis in oerder to determine the characteristics of the fracture surfaces. Test results showed that the longer the alcali treatment time in the lower the flexural stress and strain, but the the higher the flexural modulus. The composite without alkali treatment reluted in 70.39 MPa bending stress, 1.85% bending failure strain, and 3.85 GPa bending modulus, whereas the 6 hours of alkali treatment resulted in 51.70 MPa bending stress, 1.27% bending failure strain, and 4.13 GPa bending modulus. Composite with alkali-treatmed fiberdid not exhibite any fiber pull out, and also experienced debonding due to shear forces can’t afford retained by the resin.

Abstract

Powder metallurgy is one of the manufacturing processes. Upon the process, melting process is not necessary to carry out. The powder is subsequently compacted then sintered. These processes can be conducted either separately or simultaneously.  However metallurgy processes have not been commonly developed in Indonesia yet. Therefore it is necessary to carry out preliminary research that serves as a basis for developing of further process. The effect of the independent variables of the process on mechanical and physical properties of the product will be examined. The research was conducted by arranging the independent variables which consist of pressure, temperature and sintering period whereas hardness and density of product are the dependent variables.  Aluminum will be water atomized for obtaining the powder. Response surface method is used as the experimental design method.  The method can show the effect of the independent variables individually and the interaction among the variables. Data analysis will result mathematic formula showing the functional relation. The research concludes that 170 MPa compaction pressure and 500 0C sintering temperature and 40 to 50 minutes range period of sintering produces the maximum Brinell hardness number of 47 BHN. On the other hand, the effect of the independent variables to the density has not been able to be formulated.

Abstract

Penelitian ini bertujuan untuk menyelidiki pengaruh perlakuan alkali (5% NaOH) terhadap sifat tarik (tegangan, regangan, modulus elastisitas) bahan komposit berpenguat serat nanas-nanasan (bromiliaceae) dengan matrik unsaturated polyester. Karakteristik penampang patahan diselidiki dengan pengamatan menggunakan foto makro. Bahan utama penelitian adalah serat nanas-nanasan kontinyu, NaOH, dan resin unsaturated polyester. Serat yang digunakan dikenai perlakuan alkali (5% NaOH) selama 0, 2, 4, 6, dan 8 jam. Pembuatan komposit dengan metode cetak tekan pada kisaran fraksi massa serat 15% - 50. Pembuatan spesimen uji komposit dan prosedur pengujiannya mengacu pada standar ASTM D 638. Hasil penelitian menunjukkan bahwa perlakuan alkali (5% NaOH) mampu menghilangkan lapisan seperti lilin di permukaan serat sehingga serat dan resin memiliki ikatan (mechanical bonding) yang kuat. Komposit yang diperkuat serat yang dikenai perlakuan alkali memiliki kekuatan yang lebih tinggi dibandingkan dengan komposit yang diperkuat serat tanpa perlakuan.  Semakin tinggi fraksi massa serat (Wf)  maka kekuatan tariknya juga semakin besar. Pada di atas 30%, kekuatan tarik paling besar terjadi pada komposit yang diperkuat serat dengan perendaman alkali selama 4 jam, dan selanjutnya disusul oleh komposit yang diperkuat serat dengan perendaman alkali selama 2 jam pada (Wf). Komposit yang diperkuat serat perlakuan alkali selama 4 dan 2 jam juga memiliki modulus elastisitas yang lebih tinggi, yaitu masing-masing 40.71 GPa dan 50.65 GPa pada Wf sekitar 38%. Jenis patahan splitting in multiple area terjadi pada komposit yang diperkuat serat dengan perlakuan NaOH selama 4 jam, 2 jam, dan tanpa perlakuan. Namun, komposit yang diperkuat serat dengan perlakuan NaOH selama 8 jam memiliki jenis patahan patah tunggal. Berhubung penampang patahan komposit yang diperkuat serat tanpa perlakuan mempunyai mekanisme kegagalan fiber full out, maka kekuatan komposit ini pun menjadi rendah karena memiliki ikatan antara serat dan matrik yang lemah.

Abstract

AbstrakTembaga dikenal memilki keunggulan sifat fisis sehingga sering diaplikasikan bersamaan dengan baja menggunakan teknik brazing yang membutuhkan filler. Friction welding memberikan alternatif penyambungan tak sejenis tanpa filler dan asap. Penelitian ini dilakukan untuk mengetahui efek tekanan gesek terhadap sifat mekanis sambungan las gesek pada sambungan dissimilar baja-tembaga. Silinder tembaga dan baja dibubut menjadi bentuk setengah bagian dari benda uji standar JIS Z 2201. Proses pengelasan dilakukan pada putaran 1000 rpm dengan variasi tekanan gesek sebesar 30, 35, dan 40 MPa dengan tekanan tempa 80 MPa. Waktu gesek dan waktu tempa masing-masing 5 detik. Hasil penyambungan masing-masing diamati struktur mikro, kekerasan dan sifat tariknya.  Hasil penelitian menunjukkan bahwa dengan meningkatnya tekanan gesek maka daerah TMAZ melebar. Struktur mikro berbutir halus teramati di bagian baja, sedangkan di daerah tembaga, orientasi butir berubah memanjang searah dengan permukaan sambungan. Pada daerah termomechanically affected zone (TMAZ) dan welding center zone (WCZ) kekerasan masing-masing logam turun seiring dengan kenaikan tekanan gesek. Lebar daerah TMAZ yang cukup membuat kekuatan tarik tertinggi diperoleh dari spesimen dengan variasi 35 MPa sebesar 89 MPa. Metode las ini dapat digunakan untuk penyambungan logam tak sejenis baja-tembaga dengan memperhitungkan luasan daerah TMAZ. AbstractCopper is often used along with steel due to it excellence properties by using brazing technique. Friction welding technique offers an alternative technique for joining dissimilar metal without fillers and smoke. This research purpose is to study the effect of the friction pressure on the mechanical properties of steel-cooper friction welded joints. Copper and steel bars were turned into half the shape of the specimen according to JIS Z 2201. The welding process was carried out at a speed of 1000 rpm with the friction pressures of 30, 35, and 40 MPa under an upset stress of 80 MPa for 5 seconds of friction time and upset time. The results showed that with increasing friction pressure the TMAZ area was widened in fine grained microstructure for the steel region. Whereas in the copper region, the orientation of elongated grains inline with the direction of the joining surface. In the TMAZ and WCZ areas the hardness of each metal decreases with increasing friction pressure. The sufficient width of the TMAZ results in the highest tensile strength of 89 MPa. It was obtained from the specimens with friction pressure of 35 MPa. This welding method is potentially used for dissimilar steel-copper joint by considering the area of the TMAZ region.Keywords: Friction welding, dissimilar metals joint, pressure friction, TMAZ

Abstract

Pengelasan gesek diketahui memiliki keunggulan mampu menyambung dua logam yang berbeda (dissimilar). Meskipun demikian, pengelasan ini masih mengalami kesulitan dalam proses penyambungan karena perbedaan titik lebur dari kedua logam yang disambung. Agar perbedaan suhu pada daerah yang bergesekan tidak terlalu besar, perlu dilakukan pemanasan awal /preheat pada logam dengan titik lebur yang lebih tinggi. Tulisan ini membahas disain dan pembuatan mesin preheat induksi pada las gesek logam dissimilar. Pemanas induksi yang digunakan adalah prinsip-prinsip arus eddy dengan frekuensi tinggi. Mesin preheat induksi ini terdiri atas komponen utama yaitu transformator, diode, transistor mosfet, kapasitor, kumparan kerja, induktor, dan resistor. Kumparan kerja terbuat dari pipa pejal tembaga berdiameter 5 mm, jumlah lilitan, n = 6 lilit dengan tinggi kumparan 35 mm dan diameter lilitan 40 mm. Setelah terangkai, dilakukan pengujian pada silinder pejal stainless steel berdiameter 14 mm dan panjang daerah pemanasan 30 mm. Pemanasan dilakukan sehingga silinder mencapai temperatur 600 °C. Termokopel tipe K digunakan untuk mengukur temperatur silinder. Hasil pengujian menunjukkan bahwa mesin memiliki spesifikasi berupa tegangan kerja rangkaian 20 Volt dan arus maksimal 44 ampere. Temperatur naik dengan cepat hingga 600 °C setelah 70 detik pertama kemudian naik sedikit dan stabil sampai dengan maksimum temperatur 683 °C dengan waktu pengujian sampai dengan 300 detik. Daya listrik berkisar antara 320-674 watt. Hasil ini menunjukkan bahwa mesin preheater telah berhasil dibuat dan berpotensi dapat digunakan sebagai preheater pada proses las gesek dissimilar. Friction welding is known to have the advantage of being able to connect two different metals (dissimilar). However, this welding is still experiencing difficulties in the joining process because of the different melting points of the two metals being joined. In order the temperatur difference in the rubbing area is not too large, it is necessary to do preheat the metal with a higher melting point. This paper discusses the design and manufacture of induction preheat machines in dissimilar metal friction welding. Induction heaters are applied using the principle of eddy current with high frequency. This induction preheat machine consists of main components namely transformer, diode, mosfet transistor, capacitor, working coil, inductor and resistor. The working coil was made of solid copper pipe with a diameter of 5 mm, number of turns, n = 6 turns with coil height of 35 mm and diameter of coil of 40 mm. After being assembled, testing was carried out on a solid stainless steel cylinder with a diameter of 14 mm and a length of 30 mm heating area. The heating process was conducted to achieve temperatur of the higher than 600 °C. A K type thermocouple was used to measure the temperatur. The test results showed that the machine had specifications as follows: a 20 Volt circuit working voltage, with a maximum current of 44 amperes. Temperatur rose rapidly up to 600 °C after the first 70 seconds then increased slightly and was stable up to a maximum temperatur of 683 °C during 300 seconds. Electrical power ranged from 320-674 watts. These results indicated that the preheater machine was successfully fabricated and was potentially be used as a preheater equipment in the dissimilar friction welding process.

Abstract

The Lohjinawi Garbage Bank is a waste management institution in Indonesia that aims to reduce the amount of waste that ends up in landfills. The Lohjinawi Garbage Bank has been operating for several years, but still needs the strengthening of its management capacity. One way to strengthen the management capacity of the Lohjinawi Garbage Bank is through training and making paving blocks from plastic waste. Training will be conducted for the management and members of the Lohjinawi Garbage Bank in terms of sorting and processing plastic waste into raw materials for paving blocks. This training will provide an understanding of techniques and processes for processing plastic waste, as well as techniques for making quality paving blocks. In addition, the training will also provide an understanding of the marketing and management of the paving block business. After the training, paving blocks were made from processed plastic waste. The resulting paving blocks will be used to build parking areas and roads around the Lohjinawi Garbage Bank environment. Apart from that, paving blocks can also be sold to increase the income of the Lohjinawi Garbage Bank. With training and making paving blocks from plastic waste, it is hoped that the Lohjinawi Garbage Bank can strengthen its management capacity and increase its business income. In addition, using paving blocks made from plastic waste can also reduce the amount of plastic waste that ends up in landfills and reduce the use of conventional building materials that are not environmentally friendly

Abstract

Lathe machines are used to work on cylindrical objects. Tool wear is often a problem in the turning process and impacts the results of the machining process. The research aims to compare lathe insert tool wear levels TNMG160404-MA and TNMG160404-TF. The research used the experimental method directly using a lathe with variable machining on feeding (f) 0.04 mm/rev and 0.08 mm/rev, spindle (n) 540 rpm, and depth of cut (a) 4 mm. Tool wear was measured using an optical microscope by measuring the maximum edge wear on the tool (VBmax) and to determine the significance of tool wear using statistical analysis. The results showed wear level insert tool of TNMG160404-MA at a feeding of 0.04 mm/put an average of VBmax = 85.00(μm) and a feeding of 0.08 mm/put VBmax = 63.23(μm). TNMG160404-TF insert tool wear at 0.04 mm/put feed VBmax = 76.18(μm) and 0.08 mm/put feed VBmax = 58.43(μm). On a feeding, 0.08 mm/put motion, the standard deviation (s) of the TNMG160404-MA insert tool is 16.2, and the standard deviation (s) of the TNMG160404-TF insert tool is 17.8. On a feeding of 0.08 mm/rev, the results of t-count = 0.630 and t-table = 2.101, so t-count < t-table (0.630 < 2.101), the statistical analysis results using the t-test showed no significant difference in the level of wear of the two types insert tools.
