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

This study takes an object in PD. BKK Dempet Dempet City Branch Demak, where the reasons for selecting the titlebecause of the realization that achieved PD. BKK Dempet Dempet City Branch Demak 2009, 2012 and 2013 was notachieved so that it becomes a problem that must be addressed by the management of the bank. One way to boost therealization of loans obtained by the bank is to increase customer satisfaction and loyalty in lending transactions (credit)in the bank. Therefore, this study aims to identify and analyze the influence of trust, Brand Image and service quality onloyalty mediated by customer satisfaction (studies in PD. BKK Dempet Dempet City Branch Demak). Samples in thisstudy were 100 respondents who considered representative of the entire population. The sampling technique used in thisstudy purposive sampling is sampling based criteria or considerations such as: a customer of PD. BKK Dempet DempetCity Branch Demak for at least 2 years, and is domiciled in the territory Dempet, Demak. Tools of data analysis usingmultiple linear regression with mediation or intervening variables. The results show that there is a partial positive andsignificant effect of trust, confidence and quality of service to satisfaction. Partially there is a positive and significanteffect of trust, trust, quality of service and satisfaction to loyalty. The results show that the mediating effect ofsatisfaction does not mediate the effect of trust, brand image and service quality on customer loyalty.Keywords: trust, Brand image, service quality, satisfaction and loyalty.

Abstract

Periapical radiography projection is one of the most frequently used in dentomaxilofacial radiographs. The radiation source used in periapical radiographs are X-ray of ionizing radiation. The use of ionizing radiation can cause harmful effects to the body, where one of it is to the blood cells. The aim of the study was to determine the effect of a single exposure of X-ray radiation from periapical radiograph towards the total of cells on isolated monocytes. The design of the study was the Post Test Only Control Group Design.This research was conducted in the Radiology Installation Bioscience and in the Laboratorium of the Jember University Dental Hospital. The research sample was isolated monocyte cells derived from human peripheral blood (dependent variable). The sample was divided in to 2 groups randomly (the control group and the treatment group). The sample size used for the research is 6 samples in each group. The treatment group was given a single exposure periapical radiography of X-ray radiation at a dose of 1.54 mGy (independent variable). The living cells on isolated of monocytes were observed and calculated using an inverted microscope with 400x magnification using a trypan blue staining. The results of research used the Independent T-test found a significant difference (p<0.05) between the control and treatment groups. The conclusion of the research was that decreasing (31,53%) in the total of cells in isolated monocytes after a single exposure of X-ray radiation from periapical radiography.   Keywords: Monocyte, Periapical Radiograph, X-Ray Radiation

Abstract

ABSTRACTGenetic variation of leafhopper, Nephotettix virescens Distant active transmitters from endemic and non endemic areas of rice tungro disease based on RAPD marker. Leafhopper, Nephotettix virescens Distant (Hemiptera: Cicadellidae) plays an important role as a vector of rice tungro virus. However, the characters of N. virescens as a  vector from endemic and non-endemic areas of tungro disease in Indonesia have not been well characterized and also available information is limited. The objective of this research was to study the character of N. virescens active transmitter from endemic and non-endemic of areas tungro disease based on RAPD markers. The N. virescens were collected from endemic area of  Klaten (Central Java), Sleman (Yogyakarta) and non endemic area of Purwodadi (Central Java) Ngawi (East Java),  and  Pacitan (East Java). The N. virescens active transmitters were identified by their ability to transmit the virus based on Standard Evaluation System for Rice Tungro Virus,  issued by IRRI. The genetic variations of N. virescens active transmitters were determined by using RAPD-PCR marker.  Result of the research showed that three primers, OPB01, OPB10 and OPC08 amplified successfully of DNA template of N. virescens through RAPD-PCR technique. Based on the dendrogram, there were initial facts of possible genetic differences between the populations of N. virescens  from endemic  and non endemic areas of  rice tungro disease. The N. virescens from endemic area of Klaten and Sleman are similar genetically but different from the N. virescens non endemic of Purwodadi, Pacitan and Ngawi.

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.

Abstract

Difisit airtanah menjadi masalah di kota-kota besar yang berada di wilayah pesisir, hal ini dipicu dengan adanya pengambilan airtanah yang tidak terkendali sehingga menimbulkan dampak krisis airtanah yang di tandai dengan menurunnya muka airtanah dan terjadinya amblesan tanah. Zonasi penurunan muka airtanah di kawasan industri Kaligawe, pesisir Semarang, dengan menggunakan teknik geofisika gayaberat mikro 4D dan gradien vertikal 4D serta dibantu dengan leveling untuk melihat amblesan tanah yang terjadi di daerah penelitian. Pengukuran dilakukan sebanyak dua kali, yaitu pada bulan Juni 2004 dan Nopember 2005 dalam jarak rentang waktu 16 bulan dengan 47 stasiun pengamatan. Disimpulkan bahwa hampir 70% daerah penelitian mengalami penurunan muka airtanah dan amblesan dan hal itu didukung dengan adanya penurunan muka airtanah yang terpantau dari beberapa sumur pantau yang berada di sekitar daerah penelitian.
