Kopi mix berbasis gula kelapa yang diperkaya minyak sawit merah merupakan alternatif minuman tinggi antioksidan bagi perokok. Penelitian ini bertujuan untuk: 1) Mengkaji pengaruh konsentrasi minyak sawit merah terhadap sifat fisikokimia dan sensori kopi mix; 2) Mengkajii pengaruh suhu penambahan bubuk kopi terhadap sifat fisikokimia dan sensori kopi mix; 3) Mengetahui kombinasi perlakuan terbaik antara konsentrasi minyak sawit merah dengan suhu penambahan bubuk kopi berdasarkan sifat fisikokimia dan sensori kopi mix. Perlakuan ini dilakukan secara eksperimental dengan menggunakan Rancangan Acak Kelompok (RAK) yang disusun secara faktorial dengan 9 kombinasi perlakuan, dan 3 ulangan sehingga menghasilkan 27 unit percobaan. Faktor yang diteliti adalah konsentrasi minyak sawit merah, terdiri atas: M1=3 ppm, M2=4 ppm, dan M3= 5 ppm serta suhu penambahan kopi bubuk, terdiri atas: T1=102oC, T2=105oC, dan T3= 108oC. Variabel yang diamati meliputi sifat fisik dan kimia (densitas kamba, warna, kadar air, kadar asam lemak bebas, kadar gula total, kadar gula reduksi, dan total fenol), sifat sensori (aroma, rasa masis, rasa pahit, flavor, off-flavor, kesukaan aroma, kesukaan rasa, kesukaan flavor, dan kesukaan keseluruhan). Hasil penelitian menunjukkan bahwa kombinasi perlakuan terbaik kopi mix gula kelapa yaitu pada konsentrasi minyak sawit merah 3 ppm dan suhu penambahan bubuk kopi 105oC (M1T2) dengan karakteristik fisik, kimia, dan sensori yang dihasilkan adalah sebagai berikut: intensitas kecerahan 29,10; densitas kamba 0,577 g/ml, kadar air 5,35%bb, total fenol 2,697 mg/g, kadar asam lemak bebas 0,083%bk, kadar gula reduksi 3,73%bk, kadar gula total 54,32%bk, β-karoten 510,6μg/100g, tokoferol 0,69%, dan aktivitas antioksidan (DPPH) 73,1%. Karakteristik sensori kopi mix adalah: aroma agak kuat (3,64), rasa agak manis (4,04), rasa agak pahit (3,84), flavor agak enak (3,88), off-flavor sedikit kuat (4,72). Adapun tingkat kesukaan panelis terhadap produk kopi mix meliputi: aroma agak disukai (3,80), rasa agak disukai (3,84), flavor agak disukai (3,80), dan secara keseluruhan agak disukai (3,88).

Mix coffee drink-coconut sugar based enriched with red palm oil is an alternative functional drink high antioxidant for smoker.Aimed of this research were: 1) To study the effect of red palm oil concentration towards the physical, chemical, and sensory properties of mix coffee; 2) To study the effect of temperature level adding coffee powder towards the physical, chemical, and sensory properties of mix coffee; 3) Determine the best combination between red palm oil concentration and temperature of coffee powder addition based on the physical, chemical, and sensory properties. The experiment was conducted experimentally with Randomized Block Design (RBD) method, with 9 treatment combination, and 3 replication, resulted in 27 experimental unit. The tested factor:1) Red palm oil concentration (M) that used in this research were 3 ppm (M1); 4
2
ppm (M2);5 ppm (M3). 2)Temperature of coffee addition (T) were 102oC (T1); 105oC (T2); and 108oC (T3). Variables which observed were physical (colour and bulk density), chemical (water content, reducing sugar content, total sugar content, free fatty acid content, phenolic total), and sensory variabels (aroma, sweetness, bitter taste, flavor, off-flavor, favorite level of : aroma, taste, flavor, and overall). The results showed that the best combination was mix coffee drink by adding red palm oil of 3 ppm which temperature of coffee addition was at 105oC (M1T2) with characteristics follows: the intensity of the brightness value were 29.10; dencity of kamba 0.577 g/ml; water content of 5.35%bb; total phenolic of 2.697 mg/g; free fatty acid of 0.083 %bk; reducing sugar of 3.73 %bk; total sugar 54.32%bk, β-karoten 510.6μg/100g, tochopherol 0.69%, and antioksidan activity (DPPH) 73.1%..The sensory characteristic as follows: slightly strong aroma (3.64); slightly sweet taste (4.04); slightly bitter taste (3.84); slightly delicious flavor (3.88); little stong off-flavor (4.72). While the panelist`s favorite level of mix coffee drink product as follows: aroma preferences slightly (3.80); flavor preference slightly (3.80); taste preference slightly (3.84) and overall preference slightly (3.88).
