Abstract

Structured lipid (SL) containing of medium chain fatty acid (MCFA) at outer position and polyunsaturated fatty acid (PUFA) at sn-2 position has superior dietary and absorption characteristics. The most methods for the enzymatic synthesis of SL were through two steps process, so that it was inefficient. Caprilic acid was usually used as a source of MCFA. In this research, SL was synthesized by enzymatic interesterification between fish oil and lauric acid. The specific lipase from Mucor miehei was used as catalyzed. Factors, such as the incubation time, substrate mole ratio, and reaction temperature were evaluated. The incorporation and the position of lauric acid on glycerol backbone and glyceride profile were determined. The results showed that SL containing of lauric acid at the outer position and PUFA at sn-2 was successfully synthesized, and it was done through one step process. From regiospecific determination, it showed that the position of lauric acid incorporation was only at the sn-1 and sn-3. Only 0.87% of lauric acid was incorporated at the sn-2. The optimum time and temperature of the reaction, and the substrate mole ratio were 12 h, 50?C and 1:10, respectively, in which the incorporation of lauric acid was 62.8% (mol). Glyceride profile was affected by incubation time, substrate mole ratio and reaction temperature. Triglyceride concentration decreased with an increase in the incubation time (> 12 h). In contrast, the diglyceride concentration increased at longer incubation time (> 12 h). Beside, triglyceride concentration increased with an increase in substrate mole ratio to 1:10, but it decreased when mole ratio of substrate was 1:15. At higher temperature (50?C), triglyceride decreased with an increase in the reaction temperature. In summary, the SL was successfully synthesized by the interesterification of fish oil and lauric acid using specific lipase of Mucor miehei.Key words : Interesterification, fish oil, lauric acid, structured lipids, lipase

Abstract

The brown planthopper, Nilaparvata lugens Stål. (Hemiptera: Delphacidae) is a destructive and widespread insect pest throughout the rice areas in Indonesia. Rice plant resistance is an effective method in controlling the brown plant hopper. However, the resistance sources and how their mechanism for imparting induced resistance against brown planthopper remains to be understood. This research was aimed to identify plant hair and protein banding patterns, as a genetic expression, of resistant and susceptible varieties. Identification of the variation of number of plant hair were carried out by using binocular microscope, while the protein banding patterns was detected by separation on SDS-Page. Co-variants analysis was adopted to identify the groups of resistant cultivars based on protein banding patterns. The results showed that plant hair on resistant rice cultivars are different with susceptible cultivars (resistance to Pelita I/1). The plant hair on resistant cultivars are larger/longer, more abudant and grew tighter than on susceptible cultivar (resistance to Pelita I/1). However the number of plant hair have no correlation with resistance level. In the absence of brown plant hopper infestation, the expression of protein total of resistant and susceptible cultivars are not clearly separated. The susceptible Pelita I/1 varieties showed a similar banding pattern to IR 26 (biotype 1), IR 42 (resistance to biotype 2) and IR IR 74 (resistance to biotype 3), but the four cultivars are not similar to the resistant cultivar IR 36 varieties (resistance to biotype 2). Our research showed that both plant hair and protein banding patterns can not be used to identify the plant resistance. Key word: rice plant resistance, plant hair, protein banding patterns

Abstract

Belenggu is a novel written by Armijn Pane in 1938, whereas Pengakuan Pariyem is a lyrical novel written by Linus Suryadi AG that published in 1980. Both are interested to be analyzed from linguistic aspects, especially in relation to gender dan patriarchal issues. In this case, the proper approach is feminist stylistics by Sara Mills since it analyzed literary works from linguistic aspects and then is enlarged on the contexts of surroundings when it was published. The results are that Belenggu basically used masculine languages including word, phrases, clauses, sentences, and discourses when it is related to its contexts. Contextually, Belenggu represented author responses to conditions of his society in which women tried to insist their rights for equality (to men). It also represented author’s critic to women since it is better that women still work domestically and support her husband. Meanwhile, Pengakuan Pariyem is a lyrical novel that considers men and women have mutual relationships although women still work domestically and men work outside.

Universitas Muhammasdiyah MalangAbstrakPenelitian ini didasari oleh kondisi kemampuan menulis pada siswa sekolahdasar yang masih mengalami kesulitan dalam pembelajaran bahasa dansastra Indonesia khususnya menulis puisi. Hasil observasi yang dilakukanmenunjukkan selama ini, pembelajaran menulis puisi di sekolah dasarberlangsung sangat sederhana dan konvesional sehingga terkesanmembosankan. Oleh sebab itu perlu diterapkan model pemelajaran SAVIdalam pembelajaran menulis puisi. Hubungannya dengan pembelajaranpuisi, model SAVI sangat relevan karena materi menulis puisi tidak sematamatabersumber dari hal-hal yang fiktif dan imajitif. Melainkan jugabersumber dari hal-hal yang terjadi dalam realita dan ditangkap oleh indera,seperti hal yang ditangkap oleh indera pendengaran, penglihatan, gerak danintelektual. Dalam menulis puisi, model pembelajaran SAVI yangmelibatkan peserta didik secara langsung sangat efisien karena menulis puisiadalah kegaiatan yang dilakukan oleh individu sedangkan lingkungan danorang lain hanyalah merupakan stimulus. Dengan kata lain, menulis puisiadalah menulis kembali apa yang dilihat, dirasakan, dilakukan dandipikirkan ke dalam bentuk puisi.Kata Kunci: Model Savi, Menulis Puisi
