Abstract

Kopi adalah komoditas perdagangan internasional terbesar kedua setelah minyak bumi. Potensi ituditunjukkan dengan peringkat ekspor kopi Indonesia yang mencapai peringkat ke 4 terbesar dunia setelahBrazil, Vietnam dan Kolombia. Desa Nglinggo Barat Kelurahan Pagerharjo, Kecamatan Samigaluh,Kabupaten Kulon Progo mayoritas penduduknya bekerja sebagai petani kopi. Pembinaan pada petanikopi ini perlu dilakukan untuk menambah wawasan dan meningkatkan kualitas produksi hasil biji kopi.Masalah yang dihadapi petani tradisional ini adalah kesulitan untuk penanganan pasca panen saatpanen raya. Pengelolaan pasca panen kopi masih manual dan membutuhkan waktu yang lama sehinggamenurunkan produktivitas pengolahan biji kopi, selain itu pengolahan biji kopi yang masih manualdengan cara ditumbuk dapat merusak kualitas biji kopi yang dihasilkan. Tahapan pelaksanaan programmeliputi sosialisasi program kegiatan, mengundang pakar yang kompeten pada bidang pengolahan produkbiji kopi, dan memberikan bantuan alat pengupas kulit ari biji kopi sehingga dapat meningkatkankualitas produksi biji kopi yang dihasilkan dan nilai ekonominya tetap tinggi.

Abstract

Corrosion is one of the things that occurs due to damage or degradation of metals due to a redox reaction between metals and various substances in their environment so that they can produce unwanted compounds. This corrosion is also often referred to as rusting. The process of this research was carried out by calculating the loss (weight loss) and analyzing the ratio of corrosion velocity, specimen changes, the ratio of fresh water and sea water and the ratio of specimens with coating and without coating. with a research time of 14 days. From the results of immersion analysis, comparison and calculation of specimens in the corrosion process yielded a value (mm/y), specimen 1 without coating corrosion value per year 0.37 (mm/y), specimen 2 without coating corrosion value per year 0.52 (mm/y ), specimen 1 with coating corrosion value per year 0.26 (mm/y), and specimen 2 with coating corrosion value per year 0.3 (mm/y). Overall, the research conducted on the corrosion of one of the four specimens, namely the specimen without coating, experienced a decrease in mass due to corrosion, from 54.09 g to 54.04 g. Uncoated specimens in the absence of protection have a higher corrosion rate
