Abstract

Virgin Coconut Oil (VCO) merupakan produk kelapa bernilai tinggi yang dihasilkan melalui proses ekstraksi dingin tanpa pemanasan tinggi. Salah satu tahapan dalam produksi VCO adalah pencairan krim santan beku, yang berfungsi memisahkan fraksi minyak secara alami. Namun, proses pencairan secara manual dengan temperatur ruang memiliki sejumlah kekurangan, seperti waktu pencairan yang lama dan potensi penurunan mutu bahan baku, termasuk perubahan warna, aroma, serta degradasi kandungan nutrisi. Untuk mengatasi permasalahan ini, penelitian ini merancang dan mengembangkan alat pencair krim santan beku dengan sistem pemanas bertemperatur rendah (≤40°C) yang dilengkapi pengaduk berkecepatan rendah. Sistem ini bertujuan mempercepat pencairan sambil menjaga kualitas fisik krim santan, sekaligus meningkatkan efisiensi produksi VCO skala kecil hingga menengah. Hasil pengujian menunjukkan bahwa sistem kontrol mampu menjaga temperatur pemanasan secara stabil di bawah 40 °C dengan maximum overshoot sebesar 0,4 °C. Sensor RTD PT100 memiliki akurasi 98,2% dan sensor kecepatan 99,4%. Alat mampu mencairkan krim santan dalam waktu 2.035 detik (±34 menit), lebih cepat dibandingkan metode suhu ruang selama 7.365 detik (±122 menit), dengan penghematan waktu sebesar 72,36% atau percepatan 3,62 kali. Hasil ini menunjukkan bahwa sistem pemanas bertemperatur rendah dengan pengadukan efektif mempercepat pencairan krim santan beku tanpa melampaui batas suhu kritis serta menjaga mutu krim santan.

Virgin Coconut Oil (VCO) is a high-value coconut product produced through a cold extraction process without high temperature heating. One of the stages in VCO production is the thawing of frozen coconut cream, which serves to naturally separate the oil fraction. However, conventional thawing at ambient temperature has several drawbacks, including long processing time and potential degradation of raw material quality, such as changes in color, aroma, and nutrient content. To address these issues, this study designs and develops a frozen coconut cream thawing system using a low temperature heating system (≤40 °C) combined with a low speed agitator. The system aims to accelerate the thawing process while maintaining the physical quality of the coconut cream, thereby improving production efficiency for small to medium scale VCO processing.Experimental results show that the control system is able to maintain the heating temperature stably below 40 °C with a maximum overshoot of 0.4 °C. The RTD PT100 temperature sensor achieves an accuracy of 98.2%, while the rotational speed sensor attains an accuracy of 99.4%. The developed system is capable of thawing frozen coconut cream within 2,035 seconds (±34 minutes), significantly faster than the conventional ambient temperature method, which requires 7,365 seconds (±122 minutes). This corresponds to a time reduction of 72.36% or a process acceleration of 3.62 times. These results demonstrate that the low temperature heating system combined with agitation effectively accelerates the thawing of frozen coconut cream without exceeding the critical temperature limit, while preserving coconut cream quality.
