Abstract

Telah dilakukan penelitian yang bertujuan untuk mengetahui efisiensi ekstrak daun kelor dalam menghambat laju korosi pada besi hollow (baja galvalum) dengan menggunakan metode kehilanagn massa (Mass Loss), untuk mengetahui pengaruh variasi konsentrasi inhibitor ekstrak daun kelor terhadap laju korosi, mengetahui pengaruh waktu perendaman terhadap laju korosi dan untuk mengetahui waktu perendaman terhadap efisiensi inhibisi, metode yang digunakan pada penelitian ini adalah metode kehilangan massa (Mass Loss). Adapun hasil penelitian yang telah dilakukan, ekstrak daun kelor sebagai penghambat laju korosiyang digunakan sebagai inhibitor pada besi hollow (baja galvalum) dengan menggunakan medium air hujan dengan waktu perendaman 5,15 dan 25 hari dengan variasi konsentrasi 400 ppm dan 600 ppm. Hasil yang didapatkan pada sampel tanpa inhibitor pada waktu perendaman 5,15 dan 25 hari berturut turut 153,773 mpy, 11,539 mpy dan 0,483 mpy, Hasil nilai laju korosi pada penambahan inhibitor konsentrasi 400 ppm pada waktu perendaman 5,15 dan 25 hari berturut turut 135, 256 mpy, 9,929 mpy dan 0,161 mpy, Hasil nilai laju korosi pada penambahan inhibitor konsentrasi 400 ppm pada waktu perendaman 5,15 dan 25 hari berturut turut 133,646 mpy, 2,415 mpy dan 0,161 mpy. Hasil nilai efisiesnsi inhibisi pada sampel tanpa penambahan inhibitor berturut turut 12 % dan 12,8 %, hasil nilai efisiesnsi inhibisi pada sampel penambahan inhibitor konsentrasi 400 ppm berturut turut 91 % dan 98 %, %, hasil nilai efisiesnsi inhibisi pada sampel penambahan inhibitor konsentrasi 600 ppm sebesar 99 %.

Abstract

Pussui Village is one of the villages which has a quite large cocoa farm, located in Luyo District, Polewali Mandar Regency. With this high potential yield, proper post-harvest handling is required to produce high-quality dried cocoa beans. Good post-harvest handling practices have not been implemented by farmer groups in Pussui Village. The dried cocoa beans are sold directly to the traders. The intervention that can be carried out is a training program that focuses on proper fermentation and drying techniques by increasing the farmer's capability by developing their skill and knowledge and applying tools to this process. This training was expected to reduce the low quality of the dried cocoa beans which will affects the price of the cocoa beans in Pussui Village. This intervention was realized through an approach involving the provision of teaching materials in the class, practical sessions in fermentation and drying houses, as well as evaluation of post-training through questionnaires given after the training. This activity is part of the Kosabangsa 2023 program. The evaluation results show that this activity can increase participants' knowledge by 40% and 35% in fermentation and drying techniques. Furthermore, for the level of usefulness, farmers rated this activity as very useful by scores of 44% and 47%.
