Abstract

Bertambahnya jumlah populasi manusia di dunia cenderung menambah jumlah produksi sampah yang dihasilkan. Sampah yang belum dapat diolah dikarenakan beberapa keterbatasan, tentunya menyebabkan timbunan sampah di Tempat Pembuangan Akhir (TPA) semakin meningkat. Berdasarkan data pada tahun 2020 tercatat 67,8 juta ton timbunan sampah yang ada di Indonesia. Sampah yang dihasilkan memiliki waktu terurai yang cukup lama, khususnya sampah anorganik. Sampah anorganik yang paling banyak digunakan ialah sampah plastik jenis Polietilena Tereftalat (PET). Untuk mengurangi timbunan sampah plastik PET tersebut, maka pada penelitian ini dilakukan proses rancang bangun alat pelebur sampah plastik jenis PET. Metode untuk proses rancang bangun tersebut menggunakan teknik perancangan yang dilanjutkan dengan proses pembuatan alat pelebur sampah plastik PET. Hasil dari penelitian ini berupa alat pelebur sampah jenis PET yang memiliki dimensi 553 x 565 x 886 milimeter yang menggunakan limbah oli bekas sebagai bahan bakar utamanya. Alat ini dapat bekerja dari hasil pembakaran oli bekas dan uap jenuh yang dihasilkan dari proses pendidihan air.  Kalor yang dihasilkan dari pembakaran oli bekas memiliki nilai 182,2 kJ dan uap jenuh 141,512 J/s. Uap jenuh yang dihasilkan dari pendidihan air akan meningkatkan tekanan dan suhu dari proses pembakaran oli pada pipa keluaran api yang secara langsung memanaskan ruang peleburan. Dengan demikian, alat pelebur sampah plastik PET ini diharapkan akan dapat mengurangi jumlah timbunan sampah plastik yang ada di lingkungan sekitar.

Abstract

Spur gear is a toothed-shaped machine component which works by friction each other to transmit high efficiency rotational movement on shafts. This requires spur gear to possess robust mechanical properties. The sand-casting technique is widely known as a simple manufacturing process to produce high quality mechanical products with less failure. Moreover, aluminium is an alloy which owns good mechanical properties, corrosion resistance and castability. Hence, the research aims to conduct manufacturing process of spur gear using sand-casting technique made from 1100 and 6063 aluminium which followed by comparing mechanical characteristics of hardness and wear resistance. The casting process initially begins by designing and fabricating patterns, then preparing the mold and silica sand along with the aluminium melting process at temperature 600oC in a furnace, which ends by pouring the molten aluminium into the sand mold. After the spur gear was obtained, mechanical testing was examined to evaluate its hardness and wear resistance values. From the results, it was clearly found that spur gear product made from aluminium 6063 possess high hardness value (58.4 HV) and the lowest wear rate reduction (0.000827 mm3/minute). Thus, spur gear made from 6063 aluminium has the best mechanical characteristics which affects long lifespan.

Abstract

Stainless steel (SS), specifically AISI 304 and 420, was classified as austenitic and martensitic stainless steels which garnered excellent corrosion resistance (up to 650 oC) and easily to enhance mechanical properties by heat treatment. However, the machinability of these materials has not been widely studied. CNC milling process was defined as cutting process of workpiece using a rotating cutting tool which considered to improve productivity in manufacture industries. Machining parameters during CNC milling process such as cutting speed, feed rate, and depth of cut play an important role to achieve desired product with high quality. In addition, surface roughness was evaluated as pivotal factor to analyze resulted machining products of workpiece which subsequently used for direct application in vary industries. In order to study machinability of AISI 304 and 420 stainless steels, the optimization of machining parameters during CNC milling process was performed to determine their surface roughness values. The research data were analyzed by using Taguchi statistical method of S/N ratio and ANOVA. Furthermore, the results show that significant influence of machining parameters on AISI 304 austenitic stainless steel was feed rate of 82,29 %, then spindle speed of 3,75 % and depth of cut 0,63 %. Besides, for AISI 420 martensitic stainless steel, the feed rate still remains important in machining parameters of 72,93 %, then depth of cut 14.98% and spindle speed of 8.09 %. Thus, the result of this research endows more insights to know the machineability of AISI 304 and AISI 420 stainless steels.

Abstract

Geram adalah serpihan material dari suatu produk atau benda kerja pada proses pemesinan. Bentuk geram sangat bervariasi tergantung kepada jenis material benda kerja, geometri alat potong dan kondisi pemotongan. Dalam jumlah banyak, geram masih dapat diproses lebih lanjut sebagai bahan baku pada pengecoran logam atau sebagai bahan aditif pada produk lainya. Keterbatasan tempat penyimpanan dan bentuk geram yang bervariasi serta laju penghasilan geram yang sangat tinggi akan menimbulkan persoalan, oleh sebab itu perlu ada suatu usaha sehingga geram dapat disimpan dalam bentuk padatan yang kuat dan beraturan atau pun dalam bentuk serpihan yang lebih kecil. Hal ini dapat dicapai melalui proses compaction. Studi ini mengevaluasi geram dari tiga jenis material yang berbeda, yaitu St 37, stainlees steel dan S45C masing-masing ditekan di dalam sebuah square hole dengan ukuran 70 mm x 70 mm x 235 mm pada tekanan 4 ton. Metode ini dapat menghasilkan pemadatan untuk St 37 sampai dengan 81.26%, stainlees steel 79.72%, dan S45C 97.64% dari volume penyimpanan awal.  Kata kunci: aditif; densitas; geram; material; pemadatan

Abstract

AISI 1015 steels have been vigorously used to numerous automotive parts. Unfortunately, it has several mechanical shortcomings due to poor hardness, wear resistance, and strength. To tackle its crucial problem, the AISI 1015 steels have been treated by induction hardening treatment at 850 oC which subsequently cooling to the ambient temperature using different cooling media of water, salt bath, and oil. The as-prepared AISI 1015 steels were then investigated its mechanical properties involving spectrometry, microstructure observation, hardness, wear, and tensile test. The AISI 1015 treated steels after induction hardening in water cooling media exhibited intriguing microstructure of vast pearlite encircle ferrite matrix. The sample also garnered significant enhancements of hardness, wear resistance, and tensile properties. These superior mechanical characteristics are believed to be catered for the induction treatment using water cooling media which boost crystalline structure transformation deliberately. Therefore, this research affords significant promise for improved mechanical properties of the AISI 1015 steels.

Abstract

Stainless steel 316L pipe welding joints are widely used in industry, especially in the Bio-Medical field. In order to develop research on this field, the Gas Tungsten Arc Welding (GTAW) process was carried out on the butt joint of ASS 316L. In this study, the ASS 316L pipe of 89 mm (3.5 inches), a thickness of 2.6 mm, and a length of 100 mm was investigated. The effect of current variations of 30, 40, and 50A with shielding gas and Argon backing gas were analyzed. ER316L have been selected as filler metal for GTAW process. The results of microstructural observations for all currents showed the formation of dendritic and widmanstanten structures in the weld metal and austenitic phases in the base metal. The mechanical tests has been conducted to find out the ultimate tensile strength and and hardness as well as observations of the macro structure in the weld metal (WM), heat affected zone (HAZ), and base metal (BM) areas. Visual observation of the 40A current showed more stable surface and penetration results compared to the 30 and 50A currents. Observations of the macro structure were correlated with the results of visual observations of the 40A current, indicating good fusion and no defects exceeding the standard. The highest tensile strength test results were obtained in specimens with a current of 50A of 659 MPa, followed by a current of 40A of 651 MPa, and a current of 30A of 649.3 MPa. However, the highest elongation was found in specimens with a current of 40A, which was 45.3%, while specimens with currents of 30A and 50A had the same elongation value of 39.3%. The general distribution of hardness in the weld metal area was greater than in the heat affected zone and base metal areas.
