Abstract

Research lathe machining process, carried out on workpiece material T-6061 aluminum and the HSS. The problem is that a large beaker radiuschip, spindle rotation and eat optimum motion to produce lathe Al-6061 with a surface that is smooth, safe and capable of producing a high production capacity with a cutting depth (depth of cut) is constant.Optimized cutting parameters selection is very important to control the quality of the product surface cylindrical form of Al-6061 is to optimize for spindle rotation, movements meal and corner radius (Chip) furious breaker using two measures of performance, metal removal rate and the surface roughness.Response Surface Methodology (RSM).  Alleged best regression model to speed snarled income (MRR) at a rate of 95% at n = 900 rpm, f = 115 mm / put and RCB = 1.25 mm is = . While allegations of the best regression model for surface roughness (SR) at a rate of 95% at n = 900 rpm, f = 115 mm / put and RCB = 1.25 mm adalah: +0,14x2x3.  A regression model be able to describe the relationship between the combination of cutting parameters and radius chip breaker produced maximum metal removal rate and minimum surface roughness. Spindle rotation is the dominant influence on the surface roughness, whereas eating motion and spindle rotation is very influential on the metal removal rate, followed by radius chip breaker. Results obtained by iterative optimization using Response Optimizer for surface roughness (SR) at n = 950 rpm, f = 90 mm / put and RCB = 1.44 mm resulted SR 0.360 μm, while the Response Optimizer on MRR at n = 950 rpm, f = 90 mm / put and RCB generate MRR = 1.44 mm 39.55 mm 3 / sec. Key words :  Material  Removal  Rate,Optimizer Response, chip  breaker, surface roughness

Abstract

The development of SMEs is still one of the development priorities in Indonesia. One example is the Dewandaru Batik industry in Malang Regency. The business, which was started in 2017 and is engaged in batik cloth production, carries out the production process manually with limited tools. The price that is determined tends to be very cheap compared to batik marketed through the market and online galleries. Moreover, every month's limited production is the impact of the lack of technology used and little marketing. Marketing and utilization of appropriate technology are still the main obstacles faced; therefore, the solution to this problem is digitizing the marketing mix and proper technology. The method used is identifying problem-solving and assistance for increasing industrial innovation and digital marketing. The result of this activity was an increase in Dewandaru's batik industry's productivity with the help of a batik stamp tool and a dipping tub used for the coloring process. Furthermore, increasing quality makes for a broader marketing market. Batik Dewandaru also experienced improvements in business management because it made simple financial reports on the results of business management training.

Abstract

The majority of Small and Medium Enterprises (SMEs) in Malang is facing several problems, namely the lack of technology and innovation in terms of quality in production and marketing. In order to improve the competitiveness of the local economy of SMEs in Polehan Village, Malang State University through DRPM funding, it provides facilities assistance, online marketing training and business management. This activity is carried out with the intention that SMEs can be more competitive and independent for business development. In detail, the form of activities is to increase the application of science and technology in society through the design of operational training for large ball sewing machines, marketing through the Tokopedia marketplace, and business management. The results that have been achieved are increased marketing so that products / goods in the form of: footwear made from cow, sheep and snake skin can be distributed evenly through e-commerce. E-commerce used is the marketplace and Google MyBusiness which are currently in great demand by consumers. DOI: https://doi.org/10.26905/abdimas.v4i2.3560

Abstract

Melambungnya harga pakan ikan buatan pabrik (Rp. 10.000,- per kg) mengakibatkan keuntungan budidaya ikan lele semakin bertambah. Pembuatan pakan ikan secara mandiri menggunakan mesin yang sederhana, resep yang tepat, dan bahan baku pakan ikan yang murah diharapkan dapat meningkatkan pendapatan peternak ikan. Proses pembuatan pakan ikan (pelet) membutuhkan mesin penghalus (disk Mill), mesin pencetak pakan ikan dan oven pengering pakan ikan. Harga pokok produksi pembuatan pakan ikan lele secara mandiri adalah Rp. 5.500,- per kg. Hasil uji coba penggunaan pakan ikan yang diproduksi secara mandiri pada pembesaran 5000 ikan lele pada kolam terpal membutuhkan 500 kg pakan dan dapat menghasilkan panen 383 kg ikan dengan umur panen 2,5 bulan. Dengan harga jual ikan ke distributor Rp. 13.500,- per kg, keuntungan yang didapat peternak sebesar Rp. 2.420.500,-. Pada penggunaan pakan ikan buatan pabrik, berat ikan yang dihasilkan pada waktu panen adalah lebih besar yaitu sebesar 466 kg, tetapi keuntungan yang didapat peternak lebih kecil yaitu Rp. 1.291.000,-. Jadi penggunaan pakan ikan yang diproduksi secara mandiri dalam program pengabdian ini lebih menguntungkan bagi peternak ikan dibandingkan dengan penggunaan pakan ikan buatan pabrik. DOI: https://doi.org/10.26905/abdimas.v1i1.1171

Abstract

Munculnya pandemi Covid-19 sejak awal tahun 2020, menyebabkan berbagai perubahan dan penyesuaian pada berbagai bidang. Salah satunya adalah pada bidang pendidikan, yang menyebabkan perubahan kegiatan belajar dan mengajar baik di pendidikan dasar hingga di perguruan tinggi. Kegiatan belajar dan mengajar dilaksanakan secara daring. Perubahan kegiatan pembelajaran dari luring menjadi daring menyebabkan berbagai kendala, salah satunya yang dialami oleh mahasiswa tingkat akhir di Jurusan Teknik Mesin, Fakultas Ilmu Eksakta, Universitas Nahdlatul Ulama Blitar yang merasa kesulitan dalam penyusunan karya ilmiah. Kesulitan yang dihadapi oleh mahasiswa tingkat akhir juga disebabkan karena intensitas pertemuan dengan dosen pembimbing yang kurang, sehingga banyak ditemui tindak plagiasi. Tindak plagiasi ini dapat dikurangi atau dihindari dengan memanfaatkan reference tool. Berdasarkan observasi awal, diketahui bahwa mahasiswa belum mengenal dan menggunakan reference tool dalam penyusunan karya ilmiah. Kegiatan pengabdian kepada masyarakat ini dilaksanakan secara daring dengan memanfaatkan media Zoom Meeting yang diikuti oleh 50 mahasiswa tingkat akhir di Jurusan Teknik Mesin, Fakultas Ilmu Eksakta, Universitas Nahdlatul Ulama Blitar. Kegiatan ini bertujuan untuk meningkatkan keterampilan mahasiswa dalam penulisan karya ilmiah dengan memanfaatkan reference tool Mendeley. Hasil kegiatan menunjukkan terdapat peningkatan keterampilan mahasiswa dalam penggunaan Mendeley untuk menyusun karya ilmiah. Dengan demikian, diharapkan angka plagiasi dalam penulisan karya ilmiah dapat berkurang.
