Abstract

Mesin uncoiler tipe Fin N merupakan mesin uncoiler yang sering mengalami kerusakan akibat beban overload yang dimuatnya. Mesin uncoiler tipe Fin N digunakan untuk dapat meningkatkan kapasitas mesin uncoiler tipe Fin N 850 kg, sehingga proses produksi menjadi lebih efektif dan dapat meningkatkan produktivitas pekerja. Tujuan perancangan ini adalah meredesain mesin uncoiler tipe Fin N dengan kapasitas 850 Kg, sedangkan metode penelitian yang dilakukan oleh peneliti yaitu identifikasi masalah, kajian pustaka, membuat konsep perencanaan, pemilihan komponen-komponen mesin uncoiler tipe Fin N, melakukan analisis perhitungan tiap komponen-komponen mesin uncoiler tipe Fin N.      Hasilpenelitianinimenun-jukkan bahwa mesin uncoiler tipe fin N dapat memiliki kapasitas muat coil 850 kg dengan menggunakan 1) poros berdimensi 85 mm, 2) pasak poros 25x14, 3) pasak gear box 20x12, 4) bantalan tipe Roller Contact Bearing dan 5) baut pengunci coil tipe M85. Selain itu, rangka mesin yang awalnya menyatu dengan rumah bearing menjadi rangka independen serta menempel dengan pillow block.

Abstract

All agricultural tools require key components in the manufacturing process, one of which is metal. The metal commonly used in the manufacture of agricultural machinery is a type of steel with a medium carbon content. This type of metal is found in many vehicle parts, so parts with moderate carbon content are spring parts. Therefore, this study was conducted to determine the effect of temperature variations on the manufacture of agricultural equipment products made from coil springs on their mechanical properties. In this study, an analysis of the coil spring steel was carried out. The research methods used included sample pieces, heat treatment with temperature changes of 815 OC, 830 OC and 850 OC, quenching with SAE 20-50 W oil cooling media, hardness test and metallographic test. From the results of the study, the highest percentage of martensite microstructure was at 850 OC temperature specimens with a value of 64% and the lowest percentage was at 830 OC temperature specimens with a value of 42%. The high percentage of bainite microstructure is at 830 OC temperature specimen with a value of 58% and the lowest percentage is at 850 OC temperature specimen with a value of 36%. Meanwhile, the highest percentage of ferrite microstructure is at 815 OC temperature specimens and the lowest percentage is in non heat treated specimens with a value of 40%. By comparison on non-heat treated specimens which have a value of 40% ferrite and 60% pearlite. The microstructure with the largest grain shape is found in the specimen at 850 OC temperature with grain number 4 and the micro structure with the smallest grain shape is found in the specimen at 815 OC having grain number 6 with a comparison of non-heat treated specimens having grain number 7. Obtained an average value – The highest average hardness with oil cooling media on coil spring steel has a hardness value of 76.75 HRC at a temperature of 850°C. While the lowest average hardness value with oil cooling media on coil spring steel has a hardness value of 75.4 HRC, namely at a temperature of 815 °C, with a hardness ratio of 71.3 HRC in the initial conditions without heat treatment.

Abstract

Desa Sumberanyar memiliki hasil laut yang melimpah, mayoritas mata pencaharian penduduknya adalah sebagai nelayan tradisional. Salah satunya hasil laut yang banyak dihasilkan oleh nelayan di Desa Sumberanyar adalah ikan tongkol dengan hasil tangkapan mencapai 100 ton pada saat musim tangkap melimpah. Harga ikan tongkol segar pada saat melimpah dijual dengan harga yang sangat murah, yaitu sebesar Rp. 2.000,-/kg. Selama ini masyarakat Desa Sumberanyar memanfaatkan ikan tongkol untuk dijual kepasar dalam bentuk segar (belum diolah), bahkan jika panen raya sebagian ikan tongkol banyak dimanfaatkan sebagai pakan ternak dan yang tidak laku terjual sampai dibuang ditempat sampah karena sudah busuk. Tujuan yang ingin dicapai dalam kegiatan pengabdian kepada masyarakat ini adalah meningkatkan kemandirian ekonomi masyarakat kelompok ibu-ibu PKK melalui aneka olahan ikan tongkol menjadi abon dan nugget. Metode yang dilakukan dengan metode ceramah serta demonstrasi yang berkenaan dengan proses pembuatan abon dan nugget mulai dari penanganan bahan baku, cara penggunaan alat-alat produksi, proses pencampuran bahan, pemasakan sampai pengemasan. Hasil secara keseluruahan hampir 35 peserta mitra kerja dapat membuat aneka olahan ikan tongkol dengan baik dan benar .Kata kunci : Ikan tongkol, nugget, abon

Abstract

Abstract Green Manufacturing is a production process that uses input with a relatively low environmental impact and produce little or no waste or pollution. Application of green manufacturing in the production process of plastic packaging beverage bottles through several stages of the coloring process, preparation of cleaning, repair environmentally friendly, and environmentally friendly conditions. Delivery bottle plastic packaging to the manufacturer for recycling reaches ± 2-3 tons in one shipping every week. Delivery is done three times a month, so that averaged reach 8-12 tons per month for waste bottles of all brands. The purpose of this research are: 1) Knowing the positive influence between staining with cleansing preparation, 2) Knowing the positive influence between the preparation of cleaning with environmentally friendly improvements, 3) Knowing the positive effect between environmentally friendly improvements to the condition of eco-friendly, 4) Knowing the positive influence between staining with environmentally friendly conditions. This study used a survey method using data analysis Partial Least Square (PLS). Results of this research are: 1) Variable staining and no significant positive effect on the variable cleansing preparation 2) Variable cleaning preparations positive and significant impact on the improvement of environment-friendly 3) Variable environmentally friendly improvements and significant positive effect on the condition of environment-friendly. 4) Variable staining and no significant positive effect on the condition of environment-friendly.
