Purpose – The purpose of this paper is to consider the implication of self-efficacy training for international students (SETIS). International students faced various transitional challenges which also potentially attenuate their academic performance. Social Cognitive Theory (SCT) is sufficient in explaining this phenomenon as well as suggesting self-efficacy enhancement strategies. Design/methodology/approach – This paper is a speculative viewpoint on the implications of SETIS. The author reviewed relevant literature and systematically constructing the SETIS based on the SCT. The SCT was used to design an appropriate training to help international students cope with transitional challenges which significantly attenuate their academic performance. Findings – The SCT and self-efficacy theory were relevant in designing the training for international students. There are four key elements of the SETIS: goal-setting; effort explanation; modeling; and sharing and evaluation. The implementation of SETIS follows the common rule in conducting effective training including need assessment and post-training evaluation. Information from academic performance record, English as Second Language test score, General Self-efficacy Scale, Students’ Adaptation to College Questionnaire, and Focus Group Discussion is also necessary to justify the need for SETIS. Research limitations/implications – Despite theoretical evidence of the SETIS, further research is necessary to test the effectiveness of this training. Future study in this specific area should focus on examining the effectiveness of the training. Originality/value – This paper addressed important issues in international education. A systematic effort in providing robust and theoretical-based training for international students is necessary. By considering the importance of self-efficacy and academic performance, this paper had begun an initial effort in designing training for international students who are struggling for a transitional challenge. Additionally, this paper provides a practical guideline in implementing SETIS. © 2016, Emerald Group Publishing Limited.

This study aims to find out the effects of palm fiber soaked in sea water toward the palm fiber tensile strength and surface roughness. The palm fiber was soaked in sea water with a variation of 1 week, 2 weeks, 3 weeks and 4 weeks soaking time. After soaked in sea water the palm fiber was then dried at a room temperature for 3 hours. The last process is putting the palm fiber inside an oven for 6 hours at 80°.The result showed that for the fiber immersion time of 1 to 2 weeks would decrease the fiber strength, but for the 3 to 4 weeks fiber immersion time the fiber tensile strength increases. For the fiber surface roughness level on the fiber immersion time, the fiber surface roughness increases the highest level on the 4 weeks fiber immersion. Different fiber immersion time would result a different fiber tensile strength and a different palm fiber surface (arenga pinnata) roughness. The longer the fiber immersed in seawater, the higher the mechanical properties and surface roughness increases. The palm fiber properties changes could be seen in the fiber tensile test and the fiber surface roughness graph chart. © Research India Publications.

Indonesia is currently developing a renewable energy-based vegetable oils include the development of biodiesel. One way of making biodiesel is the transesterification process from vegetable oils and ethanol/methanol. The transesterification process will produce primary products such as methyl ester and byproducts/waste in the form of glycerol approximately 10-15 % so that glycerol is quite abundant. Degradation of glycerol were processed by the method of sonication can produce many other compounds include acrolein. The purpose of this study was to determine the effect of phosphoric acid catalyst in the degradation of glycerol. The process of production is done in sonication reactor type 316 stainless steel is equipped with an ultrasonic wave generator. The operating conditions of research are atmospheric pressure with water glycerol mass ratio is 1: 8. Research variable is the temperature of sonication 30, 40 and 50 °C, sonication time is 10, 30, 50, 70 and 90 minutes with and without the use of catalysts. Results of the experiment were analyzed by using Gas Chromatography (GC). The results showed that the ultrasonic wave radiation for glycerol degradation process can be used to produce other compounds such as acrolein and others. With the use of H3PO4 catalyst conversion is greater than without using a catalyst and increases with sonication time. The highest conversion obtained with the use of catalysts H3PO4 is 72.68 % in the sonication time of 90 minutes and a temperature of 50 °C, while the highest yield obtained was 49.50 % with the use of a catalyst H3PO4 at sonication time of 90 minutes and a temperature of 50 °C. © 2006-2016 Asian Research Publishing Network (ARPN).

Based on numerous research and landing trends, blue swimming crab (Portunus pelagicus) in Indonesia are presently under considerable pressure, as the volume and sizes of catches are decreasing. However, the management strategy for blue swimming crab still lacks crucial information. For this reason, a study in relation to the dynamics of the catch landing characteristics of blue swimming crab is important. Therefore, the objectives of this study are to analyse the dynamic of blue swimming crab catches. The study was conducted in Pangkajene Kepulauan, South Sulawesi Indonesia one of the focal points for landing blue swimming crab in Indonesia. The catches, both in total weight and morphometrics were compared between the monsoon season (month) and the phases of the moon. The results of this study concluded that the greatest landings of crab catches in Pangkajene Kepulauan occurred in the dry season (June) during the new moon. A comparison of the morphometrics of gear also concluded a similar result, where the width, length and weight also achieved the highest value during the dry season (June). © 2015, BIOFLUX SRL.

Cashew tree (family Anacardiaceae) grows widely in many areas of the Southeast Asia countries including Indonesia. Its fruit and nut are used forfood, whereas its leaf is one of the traditional antihypertensive medicine in Indonesia. Hypertension affects many people around the world especially in developing countries such as Indonesia. The study aimed to evaluate the in vitro antihypertension effect of purified extract of cashew leaves (PECL) using an isolated organ technique, and determine the total phenolic and flavonoid contents. The results showed that PECL at 0.5 and 1.0 mg/mL was obviously able to inhibit the contraction of isolated rat aorta induced by cumulative addition of phenylephrine. The inhibitory effect of PECL were 25.72±8.19% and 39.60±3.50% (p<0.05), respectively. PECL (1.0 mg/mL) also changed the pD2 value of phenylephrine from 6.71±0.37 to 5.93±0.33 (p<0.05), and relaxed the isolated-organ mildly by 13.11±0.72%. In addition, PECL contained the total phenolic of 19.78±0.62% and the total flavonoids of 1.97±0.04% which are equivalent to gallic acid and rutin, respectively. © 2008 IFRJ, Faculty of Food Science & Technology, UPM.
