Judul: Pengaruh Jenis Pelarut dan Suhu Terhadap Pemurnian Mono-Diasilgliserol.
Abstrak: Mono-Diasilgliserol (M-DAG) adalah emulsifier yang diperoleh dari hasil esterifikasi gliserol dan PFAD (Palm Fatty Acid Destilate). M-DAG hasil esterifikasi memiliki kemurnian rendah yang disebabkan oleh pengotor seperti asam lemak bebas dan triasilgliserol, sehingga diperlukan saponifikasi dan pengkritalan untuk menghasilkan M-DAG murni. Tujuan penelitian ini adalah mencari jenis pelarut dan suhu terbaik pada proses kristalisasi M-DAG. Rancangan penelitian yang digunakan adalah rancangan acak lengkap dengan 1 faktor, yaitu jenis pelarut yang digunakan (etanol 96%, etanol 70%, isopropil alkohol 95%) dan suhu dengan taraf (2oC, 5oC, 10oC). Parameter analisis yang dilakukan meliputi rendemen, kadar asam lemak bebas, stabilitas emulsi dan penampakan. Hasil penelitian menunjukan jenis pelarut berpengaruh terhadap rendemen dan asam lemak bebas, tetapi tidak berpengaruh terhadap stabilitas emulsi. Sedangkan pengaruh suhu juga menghasilkan hasil yang sama, suhu berpengaruh terhadap rendemen dan kadar asam lemak bebas, tetapi tidak berpengaruh terhadap stabilitas emulsi. Jenis pelarut terbaik adalah etanol 96% dengan rendemen 24,2%, kadar asam lemak bebas 29,6% dan stabilitas emulsi 49,5%,.Suhu terbaik adalah kristalisasi pada suhu 2oC dengan rendemen 16,23%, kadar asam lemak bebas sebesar 3,80% dan stabilitas emulsi 100%.

Judul: Penentuan Suhu Reaksi dan Rasio Volume Gliserol dan Palm Fatty Acid Distillate untuk Sintesis Mono-Diasilgliserol
Abstrak: Mono-diacylglycerol (M-DAG) is one of emulsifiers which can be obtained by esterification of glycerol and free fatty acids. Glycerol are used is glycerol byproduct of biodiesel production, while the free fatty acids that are used is Palm Fatty Acid Distillate (PFAD). The main objective of this research is to determine the volume ratio of glycerol and PFAD, also the best temperature for the synthesis of M-DAG. The research began with the purification of crude glycerol that produced glycerol which had 73-81% glycerol content, 1.14% ash content, and pH 5. Glycerol and PFAD were reacted using 2% of methyl ester sulfonic acid catalyst for 60 minutes then the result’s characteristic was analyzed. The best temperature and volume ratio is at 160 °C with ratio between 1:3 and 1:4. This condition resulting M-DAG with yield 32.60% and 27.20%, amount of M-DAG was 61.99% (24.68% MAG, 37.31% DAG) and 49.92% (20.27% MAG, 29.66% DAG), 70.97% and 71.19% emulsion stability, 55 °C and 56 °C melting point, pH 3, 40.01% dan 39.01% acid value, and also dry and whitey-brown physical characteristic
