Abstract

Briket adalah bahan bakar padat yang dapat digunakan sebagai sumber energi alternatif yang mempunyai bentuk tertentu. Penelitian ini bertujuan untuk mengatahui pengaruh penambahan kulit salak terhadap briket cangkang biji karet.Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan dua (2) ulangan. Faktor I adalah Penambahan Kulit Salak(S) yang terdiri dari empat taraf, yaitu :S1 = 0 %, S2 = 10 %, S3 = 20 %, S4 = 30 %, dan. Faktor II adalah Lama Pengeringan (L) yang terdiri dari empat taraf, yaitu: L1 = 1jam, L2 = 2jam, L3 = 3 jam, L4 = 4 jam. Parameter pengamatan pada penelitian ini terdiri dari kadar air, nilai kalor, dan kuat tekan. Penambahan kulit salak memberikan pengaruh berbeda sangat nyata (p<0,01) terhadap nilai kalor dan kuat tekan. Lama pengeringan memberikan pengaruh berbeda sangat nyata (p<0,01) terhadap nilai kalor, kadar air dan kuat tekan. Berdasarkan penelitian nilai kalor terbaik terdapat pada perlakuan S4L4 yaitu 5122.755 kal/g, kadar air S1L3 yaitu 36,6 %  dan kuat tekan yaitu S4L4 yaitu 5,32 kg/cm2.89Kata Kunci : Briket, Cangkang biji karet, Kulit salak

Abstract

Robusta coffee is one of the superior agricultural varieties in Salak District, Pakpak Bharat Regency because it has a strong aroma and a more bitter taste. Partner of one of the robusta coffee farmers in Salak District still use traditional tools to peel the coffee cherries they cultivate. This is an obstacle in the post-harvest processing of coffee. This coffee fruit peeling tool requires a lot of manpower, a long time, and a large percentage of unpeeled coffee cherries. Therefore, the community service team helped overcome the partner's problem with the aim of implementing post-harvest technology in coffee bean production. The method used was the provision of pulper and huller machines and practical training in using these machines in the application of post-harvest coffee processing. The results obtained were that almost 100% of the coffee fruit skin and coffee horn skin were peeled using the pulper and huller machines. The percentage of coffee beans produced by the pulper machine is 64-74% of wet coffee cherries and the percentage of dry coffee beans without horn skin produced by the huller machine is 38,18-42,19% of peeled coffee beans with pulper machine.
