Abstract

Today's laser cutting machining process is often utilized in large industries as well as individual and student scientific projects. Acrylic is one of the materials whose processing involves a lot of laser cutting, but currently many laser cutting, especially low power ones, are not optimally optimized. In this study, the author wants to optimize laser cutting with 6.5 Watt power using the Taguchi optimization method on solid black acrylic material with a thickness of 3 mm, with reference to the surface roughness value of the workpiece after being subjected to the laser cutting process using the Ra unit. The control factors included are laser distance, laser power, cutting speed and cooling time. The experimental process was carried out 27 times with replication of measurements 2 times. The best result from the experiment was the roughness measurement value of 0.782 µm while the mean roughness value was 2.271 µm. After conducting the experiment, it is known that the best results are obtained with a laser distance factor of 20.6mm, cutting speed of 70 mm/min, laser power of 6.5 watts and cooling time of 10 s. Meanwhile, the effect of factors on the surface roughness results is the laser distance 27%, cutting speed 40.9%, laser power 18.9% and cooling time 7.05%. After calibrating the laser cutting, the cutting accuracy increased from ± 1mm to ± 0.4 mm or an increase of 60%, with an average final dimension measurement of 24.87 mm.

Abstract

Mango farmers in Jatisura Village, Cikedung District, Indramayu Regency face problems, mangoes are abundantduring the fruit season so the price is cheap, while when it is not the fruit season, mangoes are dif icult to obtain,apart from that, the Home Industry of processed mango products is still done conventionally, especially in theprocess of cutting the dough mango crackers so the cut results are not uniform and require a long time. The solutionis that the partners built are still very simple, (3) the limited ability of community groups to manage processedmango product businesses, and (4) marketing access is still low and the marketing system is still conventional. Theaim of this activity is to overcome the problems faced by business actors in processed mango products. in improvingthe processing of mangoes into processed food that can be stored and marketed at any time. In the processing ofprocessed mango products which currently exist in Jatisura Village, they face several problems; (1) the processingprocess currently carried out is still conventional, (2) a business management system that ensures the quantity andquality of mango fruit production into mango crackers through the application of production technology and digitaltechnology which can provide added value for home industries. Increased product processing is carried out byapplying production technology, such as the use of cutting machines, slicing machines and other processingequipment, as well as the application of digital technology to increase product promotion and marketing. The resultsof this activity have a positive impact on home industry players in processed mango products in the production andmarketing processes. ABSTRAK Petani mangga di Desa Jatisura, Kecamatan Cikedung, Kabupaten Indramayu menghadapi permasalahan, manggamelimpah pada musim buah sehingga harga murah, sementara saat tidak musim buah, mangga sulit didapat, selainitu Industri Rumah Tangga produk olahan mangga masih dilakukan secara konvensional terutama pada prosespemotongan adonan kerupuk mangga sehingga hasil potongan tidak seragam dan memerlukan waktu yang lama.Solusinya adalah dibangun mitra masih sangat sederhana, (3) terbatasnya kemampuan kelompok masyarakat dalammengelola usaha produk olahan mangga, dan (4) masih rendahnya akses pemasaran dan sistem pemasaran masihbersifat konvensional Tujuan dari kegiatan ini untuk mengatasi permasalahan yang dihadapi pelaku usaha produkolahan mangga dalam meningkatkan mengolah mangga menjadi makanan olahan yang dapat disimpan dandipasarkan setiap saat. Pada proses pengolahan produk olahan mangga yang saat ini sudah ada di Desa Jatisura,mereka menghadapi beberapa permasalahan; (1) proses pengolahan yang dilakukan saat ini masih bersifatkonvensional, (2) sistem pengelolaan usaha yang kuantitas dan kualitas produksi buah mangga menjadi kerupukmangga melalui penerapan teknologi produksi dan teknologi digital yang dapat memberikan nilai tambah bagiindustri rumah tangga Peningkatan proses pengolahan produk dilakukan dengan penerapan teknologi produksi,seperti penggunaan mesin pemotong, mesin peniris, dan peralatan pengolahan lainnya, serta penerapan teknologidigital untuk peningkatan promosi dan pemasaran produk. Hasil dari kegiatan ini memberikan dampak positif padapelaku industri rumah tangga produk olahan mangga dalam proses produksi dan pemasaran.

Abstract

Extrusion technology is one way that can be done to produce a product. The extruder machine is a tool that is quite simple but has its own uniqueness, the way this tool works is to insert raw materials which will be processed and then pushed out through a die in accordance with the desired shape. The purpose of this research is to design an extruder in order to produce a cylindrical product (filament), and to recycle waste into a product that has added value and economic value, so that it can be applied to society as an effort to reduce plastic waste. The research method used is development research with the determination of several variables, namely: control variables in the form of plastic material with the type of PET and HDPE, the independent variables are temperature and engine speed (rpm), and the dependent variable is the time needed to produce a product. The results obtained for the PET type plastic have the characteristics of fast liquid and runny, the results are discontinuous (discontinuous), brittle (brittle), for HDPE it has the characteristics of liquid and hard, continuous yield, the resulting surface looks rough with flexible plastic properties, strong and elastic, while for the mixture of PET and white HDPE, the characteristics are liquid, and continuous. This mixture of PET and HDPE has a long drying time of up to 1350 seconds.
