Judul: Kajian Pencampuran Minyak dan Lemak (Minyak Kelapa Sawit, Stearin, dan Minyak Kelapa) terhadap Karakteristik Minyak Campurannya di PT Sinar Meadow International Indonesia
Abstrak: PT Sinar Meadow International Indonesia is a manufacture industry producing margarine and shortening. Both products are made from several type of vegetable oil or fat that combined together into an oil blend. Formulation of the oil blend could affect the characteristic of the margarine and shortening products. Oil blend in this research consist of (1) palm oil (PO)/palm stearin (PS), (2) palm oil (PO)/coconut oil (CNO), and (3) PO/PS/CNO. Oil blend characteristics such as solid fat content (SFC) and slip melting point (SMP) of PO, PS, CNO and their binary blends at 1:1, 1:0, 1:9, 2:8, 3:7, 4:6, 6:4, 7:3, 8:2, 9:1 ,0:1 (w/w) were evaluated and compared with theoretical approach so that the correlation of that parameter could be analyzed. SFC was observed in four temperature observation; 10⁰C, 20⁰C, 30⁰C and 40⁰C using low-resolution Nuclear Magnetic Resonance (NMR). Oil blend PS/PO is currently having linier predictable SFC curve and there is no significance difference from theoretical curve. SFC curve for CNO/PO is linear only when observed in 10⁰C and 30⁰C. CNO/PO/PS with fixed proportion of 10%CNO having SFC curve pattern like oil blend PO/PS. SFC curve of CNO/PO/PS with varied CNO proportion is sharper. SFC curves from oil blend PO/CNO and CNO/PO/PS are significantly different from theoretical value. Higher proportion of PO resulting in higher SMP, while increased proportion of CNO is decreasing SMP. There is significant difference SMP in each formulation of oil blends.

Judul: Kajian mutu minyak sawit kasar dan analisis karakterisrik olein serta stearin sebagai hasil fraksinasinya
Abstrak: Crude Palm Oil (CPO) is a vegetable oil obtained from oil palm fruit extraction process (Elais guinneensis) with reddish orange colour. Standards applicable in Indonesia for CPO released by the National Standardization Agency stated in the document SNI 01-2901-2006 include free fatty acids (maximum 0.5%), moisture and impurities (maximum 0.5%), iodine value (50-55 g yodium/100 g), and reddish orange. In addition to chemical characteristics, other characteristics CPO such as carotene content and DOBI are also important to know as additional data. To increase the value-added palm oil, fractionated CPO usually produces two components, namely liquid olein and stearin with solid form. This study aims to obtain quality data CPO based on SNI-01-2901-2006, carotene, DOBI, and investigate the characteristics of the olein and stearin. Analysis of five types of CPO samples show different data on each CPO character. The result showed moisture content and impurities 0.33-5.39%, free fatty acids 3.84-5.88%, iodine value 50.38-54.15 g yodium/100 g, carotene content 428.28-815.56 ppm, and DOBI 1.34-3.11. The variation can be influenced by several factors including the processing of each palm oil mill and palm fruit oil condition of maturity that will be processed into crude palm oil. Fractination process carried out by melted CPO at 50 °C. The melted CPO was cooled until 15 °C with cooling rate 5 °C/30 minutes. Then crystallization carried out at 12°C for 16 hours. Separation was done by vacuum filter to get olein and stearin. The Olein and stearin were produced from fractination were analyzed. The results showed iodine value, slip melting point, and carotene content for olein consecutive 57.75-60.02 g yodium/100 g, 18.33-24 °C, and 438-536 ppm. While for stearin iodine value 34.95-42.32 g yodium/100 g, slip melting point 50.33-52 °C, and carotene content 215-276 ppm. Olein and stearin have very different characteristics.

Abstrak: Balantiosis merupakan suatu penyakit pada manusia dan ababi yang disebabkan oleh Balantidium coli. Penyakit ini pertama kali diamati oleh Kalmsten pada tahun 1857 pada pasien yang mendrita diare, sedang balantidiosis pada babi pertama kali dilaporkan oleh Leukart pada tahun 1862. Parasit ini merupakan protozoa terbesar yang berada pada usus manusia dan babi dan salah satu Giliata yang patogen.
