    Abstract
    The aim of this research was to find the effect of the ratio of cocoa powder with palm oil and temperature on the quality of cacao jam. This study was conducted using compeletly randomized design (CDR) with two factor i.e : the ratio of cocoa powder with palm oil (K¬1 = 40 g : 22 g, K2 = 38 g : 24 g, K3 = 36 g : 26 g, K4 = 34 g : 28 g) and temperature (P1 = 50 oC, P2 = 55 oC, P3 = 60 oC, P4 = 65 oC). Parameters analyzed were water content, ash content, fat content, spreadness value and organoleptic values of colour, flavor and taste. The result showed that the ratio of cocoa powder with palm oil had highly significant effect on all parameters except on water content. Temperature had highly significant effect on all parameters except on water content and organoleptic values of colour. The interaction of the ratio of cocoa powder with palm oil and temperature had no significant effect on all parameters. The ratio of cocoa powder with with palm oil of 36 g : 26 g at 60 oC produced the best and more acceptable quality of cocoa jam.
     
    Penelitian ini dilakukan untuk mengetahui pengaruh substitusi minyak sawit dan suhu pemanasan terhadap mutu selai cokelat. Penelitian ini dilakukan dengan menggunakan metode rancangan acak lengkap dengan dua faktor yaitu perbandingan tepung kakao dengan minyak sawit (K¬1 = 40 g : 22 g, K2 = 38 g : 24 g, K3 = 36 g : 26 g, K4 = 34 g : 28 g) dan suhu pemanasan (P1 = 50 oC, P2 = 55 oC, P3 = 60 oC, P4 = 65 oC). Parameter yang diamati meliputi kadar air, kadar abu, kadar lemak, daya oles dan nilai organoleptik warna, aroma dan rasa. Hasil penelitian menunjukkan bahwa perbandingan tepung kakao dengan minyak sawit memberikan pengaruh berbeda sangat nyata terhadap semua parameter kecuali kadar air yang berbeda tidak nyata. Suhu pemanasan memberikan pengaruh berbeda sangat nyata terhadap semua parameter kecuali kadar air dan nilai organoleptik warna yang berbeda tidak nyata. Interaksi antara perbandingan tepung kakao dengan minyak sawit dan suhu pemanasan memberikan pengaruh berbeda tidak nyata terhadap semua parameter. Perbandingan tepung kakao dengan minyak sawit 36 g : 26 g dengan suhu pemanasan 60 oC menghasilkan selai cokelat yang terbaik dan dapat diterima.
