Abstract

Darul Muttaqin Islamic boarding school product production activities are very dependent on the equipment that supports the production of these products. By increasing the reliability of production equipment, production from Islamic boarding schools will increase so that the economic level can be achieved well. Production equipment whose reliability is maintained by maintenance includes chili sauce making machines, tempe chips making machines, transportation equipment and other workshop equipment. The maintenance process is carried out by starting with mapping damage data for each component of the existing equipment. This data is taken from several sources that are close to or equal to existing treatments. From the existing analysis, several care and maintenance processes need to be carried out on certain parts of the equipment. The problem found by the Darul Mutaqin Islamic boarding school is a lack of knowledge regarding the proper maintenance process. This maintenance is carried out by the students of the Darul Mutaqin Islamic boarding school with direction and supervision from the service team from the Mechanical Engineering department of Brawijaya University. This activity will result in an increase in students' skills in the field of maintenance.

Abstract

Kemajuan material komposit berbahan serat alam terus mengalami perkembangan karena keberadaannnya yang melimpah, murah dan ramah lingkungan. Komposit umumnya tersusun atas matriks polimer dan material pengisi atau serat sebagi penguat. Pemanfataan serat alam yang dapat dieksplorasi sebagai material komposit baru yaitu serat goni yang memiliki keunggulan seperti ramah lingkungan dan harganya lebih murah dibandingkan fiberglass. Penelitian ini bertujuan untuk mengetahui pengaruh serat goni terhadap kekuatan impact dan kekuatan bending komposit bermatriks polyester dengan variasi fraksi berat serat 0% hingga 40%. Metode pembuatan spesimen menggunakan metode hand lay-up dan perendaman pada serat menggunakan NaOH 5% selama dua jam. Material komposit dilakukan pengujian untuk mengetahui sifat mekaniknya meliputi pengujian impact dan pengujian bending. Hasil pengujian impact dan bending tertinggi terjadi pada material komposit berbahan serat goni sebanyak 40%. Nilai impact mengalami kenaikan 506,6% setelah penambahan serat goni sebesar 0,076 J/mm2. Sedangkan nilai bending mengalami kenaikan sebesar 168,4% (44.39 MPa).

Abstract

The corrosive coastal environment will result in a high corrosion rate for any equipment installed there. This is due to the constant exposure to saltwater, high humidity levels, and strong winds. Therefore, it is crucial to use corrosion-resistant materials and regularly maintain the equipment to ensure its longevity in such an environment. One method to reduce the rate of corrosion is to pay close attention to the manufacturing parameters of these components, one of which is the face milling process. The aim of this study is investigating the effect of face milling process with different dept of cut using minimum quantity lubrication method with corn oil as a renewable vegetable cutting fluid. In this study AISI 316L stainless steel was face milled using HAAS VF-2 CNC machine. The depth of cut is varied between 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, and 0.6 mm. The results demonstrated that the greater the depth of cut, the greater the surface roughness value that will be generated. It is resulting in increment in the corrosion rate value.

Abstract

Permintaan kualitas produk yang semakin meningkat sejalan dengan kebutuhan dan permintaan dari pasar. Aluminium merupakan salah satu bahan yang sering digunakan dalam industri. Salah satu metode yang umum diterapkan dalam pembentukan aluminium adalah metode pengecoran cetakan pasir. Tujuan dari pada penelitian ini untuk mengetahui pengaruh penambahan magnesium dan seng pada aluminium 7075 terhadap nilai uji tarik dan uji bending dengan metode pengecoran cetakan pasir. Variabel yang digunakan yaitu variabel bebas yang terdiri dari spesimen variasi 1 menggunakan bahan aluminium sebanyak 200g, spesimen variasi 2 menggunakan bahan aluminium sebanyak 188g dengan campuran magnesium sebanyak 12g dan spesimen variasi 3 menggunakan bahan aluminium sebanyak 188g dengan campuran seng sebanyak 12g. Hasil pengujian pada uji tarik diperoleh bahwa tegangan tertinggi terjadi pada spesimen variasi 2 mencapai 63,86 MPa dan perpanjangan sebesar 6,36 mm. Sedangkan pada uji bending kekuatan tertinggi pada spesimen variasi 1 dengan hasil 290,83 MPa. Hasil spesimen terbaik pada uji tarik dapat diimplementasikan pada pembuatan suspensi kendaraan, sedangkan pada uji bending dapat diimplementasikan pada pembuatan swing arm.

Abstract

Pengembangan pola komunikasi tindak tutur dipilih dalam kegiatan UMKM jamu tradisional dari kelompok Toga King Betiri Desa Andongrejo, Kecamatan Tempurejo, Kabupaten Jember karena dirasa sesuai dengan kondisi masyarakat disana yang menggunakan strategi pemasaran dari mulut ke mulut. Terdapat dua fokus yang menjadi kajian pokok dalam kegiatan ini, yaitu: pertama, jenis tindak tutur yang meliputi: tindak tutur lokusi, tindak tutur ilokusi (terdiri dari: asertif atau representatif, komisif, direktif, ekspresif, dan deklaratif), dan tindak tutur perlokusi; kedua, wujud tindak tutur yang meliputi: verbal (terdiri dari: pernyataan, pertanyaan, dan perintah), non-verbal, tertulis, visual, simbolik, mimikri, dan multimodal sebagai strategi marketing dengan memperkenalkan jamu tradisional kepada komunitas senam sekecamatan Tempurejo di lingkungan kelompok Toga King Betiri Desa Andongrejo. Kegiatan pengabdian dilaksanakan dengan metode brainstorming, diskusi, dan demonstrasi. Akhirnya, kegiatan pengembangan tindak tutur diharapkan meningkatkan sikap, pemahaman dan keterampilan yang terintegrasikan dalam upaya optimalisasi strategi marketing jamu tradisional di kelompok Toga King Betiri Desa Andongrejo.

Abstract

This work investigates grape seed oil as a green substitute for conventional mineral-based cutting fluids to reach sustainable manufacturing methods. The application of grape seed oil as a cutting fluid in the machining of 316L stainless steel using the MQL method has not been documented in prior research studies. In this work, the study focuses on determining the effect of the grape seed oil on the surface integrity and comparing these findings to standard dry machining conditions by examining surface topography, roughness, and corrosion resistance at three different spindle speeds (1500, 1800, and 2100 rpm). Results of experiments showed that grape seed oil greatly improved surface quality and corrosion resistance. Surface roughness dropped noticeably by 61.6% at 1500 rpm as opposed to dry machining. Likewise, changes in surface roughness noted were 54.0% at 1800 rpm and 54.9% at 2100 rpm. Furthermore, the potentiodynamic polarization data show that the grape seed oil greatly prevents post-machining corrosion of 316 L stainless steel. The corrosion rates of the material face milled using grape seed oil were decreased by 78.6%, 74.6%, and 80.8% at spindle speeds of 1500, 1800, and 2100 rpm, respectively, when compared with dry face milling. These results indicate that grape seed oil demonstrates its ability as a cutting fluid even for high-speed machining operations. Hence, grape seed oil can address industrial demands for more environmentally friendly manufacturing methods.

Abstract

The current study provides a comprehensive discussion regarding statistical analysis of dimensional accuracy comprising thickness, gauge section width, circularity and cylindricity for 3D printed polylactic acid (PLA) specimens according to the dimensional specifications of ASTM D638 standard type IV, which are optimally built via fused deposition modelling (FDM). This work focuses on investigating the primary influences of 3D printing parameters as input factors consisting of nozzle temperature, infill density as well as layer height on dimensional deviation of the printed specimens. The confirmation tests are implemented in this study to ensure the experimental work's reproducibility. The resulting data shows that layer height dominates the effects, namely 80, 88, 81 and 81% on thickness, gauge section width, circularity and cylindricity. Meanwhile, nozzle temperature gives the second considerable influence on dimensional deviation of printed specimens, around 16, 9, 16 and 17%. Conversely, infill density promotes a negligible effect on the dimensional error of such specimens. Furthermore, the confirmation tests indicate that the experimental works are highly reproducible. These findings can contribute significantly to the additive manufacturing technology for PLA material, especially when the printed specimens are used for specific applications in biomedical, engineering and aerospace fields.
