Abstract

Polimer Ultra High Molecular Weight Polyethylene (UHMWPE) telah digunakan secara luas sebagai komponen tibial berpasangan dengan titanium alloy, stainless steel (SS), cobalt chrom alloy dan ceramic sebagai komponen femoral pada sendi lutut tiruan. Stainless steel memiliki ketahanan korosi dan bio-compatibility yang baik dan harganya relatif lebih murah dibandingkan yang lain. Penelitian ini bertujuan untuk mengetahui pengaruh implantasi ion nitrogen pada permukaan SS 316L terhadap keausan UHMWPE. Penelitian ini menggunakan UHMWPE, SS 316L dan sebagai pelumas digunakan BS dengan konsentrasi 30 g/l dicampur dengan sodium azide(NaN3) 0,2% - 0,3% g/l sebagai anti bakteri. SS 316L diimplantasi dengan ion nitrogen dengan energi 100 KeV, arus 100 μA, waktu implantasi 90 menit Variabel tetap yang digunakan kecepatan 70 mm/s, beban 180 N, jarak tempuh 90 km, menggunakan mesin undirectional pin on plate. Hasil penelitian ini menunjukkan bahwa faktor keausan UHMWPE oleh SS 316L dengan implantasi ion nitrogen terjadi penurunan 100% (6,59491 x 10-8 mm3/Nm). Sedangkan keausan UHMWPE oleh SS 316L tanpa implantasi sebesar 1,31898 x 10-7 mm3/Nm.Kata kunci : UHMWPE, SS 316L, Bovine serum, implantasi ion, faktor keausan

Abstract

Anchovy (Stolephorus spp) is a main target of lift-net fishery, and it is a main income for the fisherman for long time in Saramaake Village, East Halmahera District. Production in a large number with bulky marketing system and a limited processing activity affect a limited economical value for the community of the village. This community empowerment activities had been done for 6 months, from June–December 2017, aimed to develop the anchovy product and the certification. Methods used in this activity were training and mentoring. Objective targets of the activity were fishermen and fisherman’s wife which are members of Common Business Group and cooperation. Some activities have been done for product development (chili sauce packaged anchovy and labelling) and product certification (certification of halal from the Institute Assessment of Food, Drug and Cosmetics Indonesian Council of Ulama and certification of food of Household Industry from Public Health Service Office in District of East Halmahera). Based on the result of training and mentoring, the object community had gained a knowledge and technology related to the fish processing and certification. Certified marine product have a wider market and marketable in some shops in Ternate and Buli.
