Sistem Pendukung Keputusan Pengangkatan Guru Tetap Menerapkan Metode Weight Aggregated Sum Product Assesment (WASPAS)

Abstract: Evaluation of honorary teachers is an activity that is generally high school or vocational. It is useful to know the results of teaching honorary teachers to their students. Assessment, evaluation and rewarding can be done to spur the performance of the teachers in teaching and learning process so as to improve teacher achievement, the assessment is done to obtain the honorable teachers who will be appointed as permanent teachers. In determining the order of permanent appointment of teachers, it often appears subjective from the decision-makers, so that there are problems and this causes the difficulty in determining prospective teachers. To determine the recommendation of the teacher can still be used the method of Weight Aggregated Sum Production Assessment (WASPAS). WASPAS method can be used to process the honorarium of honor teachers with the criteria that have been determined.

Ultrashort Pulse Laser Lift-Off Processing of InGaN/GaN Light-Emitting Diode Chips

Abstract: Gallium nitride (GaN) film delamination is an important process during the fabrication of GaN light-emitting diodes (LEDs) and laser diodes. Here, we utilize 520 nm femtosecond laser pulses, exploi...

Spondias pinnata (L. f.) Kurz. (Anacardiaceae): Profiles and Applications to Diabetes

Abstract: Diabetes is a major global public health problem. It refers to metabolic disorder characterized by chronic high blood sugar. People with diabetes are at increased risk of cardiovascular, peripheral vascular, and cerebrovascular diseases. Recent researches provide evidence that diabetes can be prevented by changes in the lifestyles. It is likely that any type of lifestyle activities—whether sports, household work, gardening, or dietary habit in particular consuming herbal drinks—are beneficial in preventing and treating diabetes. The use of Spondias pinnata leaves is considered an integral part of the Balinese ethnobotanical tradition, and is used to make a herbal-medicinal beverage. The species possesses strong antioxidant activities based on ABTS•+ and DPPH assays, and contain large amounts of phenolic compounds mainly responsible for free radical scavenging activities. Our respondents in the traditional villages in Bali have been using antioxidants and polyphenols as a part of their traditional medicine for centuries, and some of them mentioned that S. pinnata leaves is used in the prevention and treatment of diabetes. Further study is essential in order to better understand the therapeutic values of S. pinnata leaves and its role in the prevention and treatment of diabetes.

The Bioremediation Potential of Hydrocarbonoclastic Bacteria Isolated From a Mangrove Contaminated by Petroleum Hydrocarbons on the Cilacap Coast, Indonesia

Abstract: The main purpose of the study was to isolate strains of bacteria capable of degrading hydrocarbons from contaminated mangroves and to investigate the ability of the isolated bacteria to degrade total petroleum hydrocarbons (TPH) in a microcosm model of an oily sludge. The potential use of these bacteria strains as environmental clean-up agents was tested by culturing them with six different polyaromatic hydrocarbon (PAH) compounds (phenothiazine, fluorene, fluoranthene, dibenzothiophene, phenanthrene, and pyrene). Six viable and culturable bacteria were isolated, and the 16S rDNA sequence for each was amplified using the primers 9F and 1510R. Sequence results were compared using the National Center for Biotechnology Information (NCBI) BLAST program and, combined with phenotypic and phylogenetic data, were used to identify three strains that belonged to the Bacillus genus and were most closely related (98–99%) to Bacillus aquimaris, Bacillus megaterium, and Bacillus pumilus. The other three strain...
