Abstract

The synthesis of nanoparticles using thermal DC plasma method is a simple method for ease of installation and high efficiency is due to the rate of precursor that can be controlled. Micro-sized aluminum powder is synthesized using thermal DC plasma undergoing a process of evaporation as it passes through high temperature plasma flame, where kemuadian oxidized aluminum particles which evaporates the particles are split and binds with oxygen to form aluminum oxide or also known as alumina (Al2O3). In this experiment, the flow rate of oxygen plasma parameters at 35 SCFH (Standard Cubic Feet per Hour) and 20 amperes flows with precursors rate variation of 1.16 g / min, 3.19 g / min, and 3.5 g / min. Precursors used is 88 micro sized aluminum powder. To determine the morphology of nanoparticles of alumina testing scanning electron microscopy (SEM), the morphology form of nanosphere. Results of the analysis showed that the rate of precursor low causing agglomeration level slightly while the higher rate of precursor agglomeration rate also increased. At the rate of precursor 1.16 g / min, nanoparikel undergo agglomeration with an average particle size of 36.55 nm, and then at a rate of 3.19 gr precursor / mnt an average particle size of 46.49 nm, and at a rate of 3.5 gr / mnt an average particle size of 46.49 nm. The powder nanoparticles were then characterized using X-ray defraksi (XRD) where all alumina nanoparticles were synthesized showed alumina phase that is formed is a phase δ-Al2O3.

Abstract

Metal matrix composites generally use Aluminum (Al) as its matrix because of its low density, high processing, and high ductility. Ductility is an important factor that must be possessed on the metal matrix composite because the amplifier used is rigid and brittle. Alumina (Al2O3) is used as a reinforcing particle in a metal matrix composite because it has good thermal stability and hardness as well as a high Young modulus. Aluminum-silicon alloys (Al-Si) are excellent alloys of good melting, which have a good surface, without brittleness, and are excellent for cast alloys. The addition of magnesium (Mg) resulted in a modified rate of silicone eutectic for Al-Si-Mg, with enhanced magnesium (Mg) levels, increased alloy tensile strength but a decreasing percent elongation value. Strontium (Sr) is a common element used to modify eutectic and Si-shaped phases of rough acicular into finer and rounded fibrous forms. A metal matrix composite with a nano-sized Al2O3 particle amplifier can be fabricated using stir casting method with the addition of Mg as a Al2O3 wetting agent. Test results of the addition of Mg, Sr, and nano-Al2O3 to the highest hardness of ADC12 / nano-Al2O3 composites were found in ADC12-8Mg-0.03Sr / 2.5nano-Al2O3 variation at 78.92 HRB. Keywords : Composite Al/nano-Al2O3, alumina, magnesium, strontium, stir casting, hardness

Abstract

Sepeda motor merupakan salah satu alat transportasi yang banyak digunakan oleh penduduk Indonesia. Alasannya sepeda motor lebih praktis dan lebih hemat jika dibandingkan angkutan umum. Dalam beberapa tahun terakhir, energi merupakan salah satu permasalahan yang krusial, dikarenakan nilai produksi minyak bumi berbanding terbalik dengan nilai konsumsinya serta semakin menipisnya deposit sumber cadangan minyak dunia. Tujuan penelitian ini untuk mempelajari tentang pemanfaatan hydrocarbon pada bahan bakar dengan cara dipecah menjadi atom hydrogen (H2) dan carbon (C) menggunakan pipa katalisator yang dipanaskan terhadap unjuk kerja motor bensin SupraX 125. Bahan bakar dipanaskan menggunakan katalis yang memiliki panjang 20 cm dengan pengaruh diameter annulus konsentris pada HCS (Hydrocarbon Cracking System). Hasil dari penelitian menyebutkan metode HCS (Hydrocarbon Cracking System) sangat efektif digunakan sebagai power suplemen untuk menghemat bahan bakar. Selisih nilai SFCe bahan bakar premium terhadap variasi perlakuan HCS sebesar 0.5 kg/HP.Jam. Pemasangan HCS mempengaruhi terjadinya penguraian atom Hydrogen (H) yang membuat pembakaran lebih cepat. Hasil uji emisi secara keseluruhan menunjukkan peningkatan kualitas pada emisi gas buang. Prosentase CO menurun yang diakibatkan peningkatan O2 dalam pembakaran yang sesuai dengan penurunan kadar HC. CO berkurang pada ruang annulus konsentris yang semakin besar. Ini menunjukkan adanya masalah pada mesin yang dikarenakan adanya ketidaktepatan waktu penyalaan bahan bakar. Kata kunci : katalis, annulus konsentris, dan HCS (Hydrocarbon Cracking System).

Abstract

Kampas rem merupakan salah satu komponen dalam kendaraan yang memiliki peranan penting terhadap keselamatan dan kenyamanan pengendara. Penggunaan yang terus meningkat serta perkembangan teknologi yang semakin maju dengan banyaknya produk yang beredar dipasaran, maka penelitian ini melakukan eksperimen menggunakan metode metalurgi serbuk dengan tujuan untuk mendapatkan temperatur sintering optimal guna mencapai nilai kekerasan optimal.Penelitian ini menganalisa volume serbuk arang kayu glugu dan serbuk aluminium dengan matrik resin phenolic, dengan variasi fraksi volume (40%,20%,40%). Tahapan penelitian, pertama melakukan persiapan alat dan bahan, menimbang bahan dan melakukan pengadukan bahan secara merata, selanjutnya melakukan proses penekanan selama 10 menit dan dilakukan sintering secara bersamaan pada suhu 1250C, 1750C, 2250C selanjutnya dilakukan proses pengujian kekerasan. Dari hasil pengujian pada penelitian ini didapatkan nilai kekerasan rata-rata yang memenuhi standart kampas rem SAE J661 sebesar 68-106 HRB. Spesimen dengan suhu sintering 1250C, 1750C,2250C sebesar 71,31 HRB, 85,88 HRB, 79,85 HRB. Peningkatan suhu sintering berdampak pada bahan yang digunakan, karena peningkatan suhu dan pendinginan secara perlahan dapat menurunkan kekerasan aluminium. Selain itu resin phenolic akan cepat mengeras (sifat thermosetting) seiring peningkatan temperatur sintering dan tidak terjadi pergerakan selama kompaksi mengakibatkan porositas tidak berkurang, sehingga dapat menurunkan sifat material. Kata Kunci: kampas rem, sintering, kekerasan, metalurgi serbuk

Abstract

Success in the injection molding process is seen from the results of products that do not produce defects. Warpage defects are one of the defects resulting from the injection molding process. One way to measure warpage defects is to use the ImageJ application. The data processing stage in this study uses the Taguchi method statistical method with two independent variables namely holding time and mold temperature, each of which has three factors and repeated data three times, which aims to obtain more accurate values. The results showed a very influential variable is the holding time parameter then the mold temperature parameter. The higher the level of holding time parameters, the smaller the result of warpage defects. Unlike the holding time parameters, the best mold temperature parameters at the middle level, the result will be a small warpage defect produced. The experimental results of the highest level value on the holding time parameter are 15 seconds while in the mold temperature the value of the middle level is 50 ° C which produces a defect of 1%. While the lowest holding time parameter value is 5 seconds and the highest mold temperature level parameter value of 70 ° C is the worst variation of parameters because it produces a defect of 22%.
