Abstract

We investigated the effect of sector (position in canopy) on translocation and distribution of 13C-photosynthates in  mangosteen trees and related the findings to previous analyses of fruit quality. Our experiment was conducted on three 25-year-old mangosteen trees. Tree canopies were divided into 9 sectors based on height (bottom, middle, top) and width (inner, center, outer). One branch from each sector was labeled with 13CO2 in December 2003. Immediately after labeling, 13C concentration in leaves from middle sectors was higher than that in leaves from other positions. 13C concentration in all leaves decreased rapidly for 24 h after 13C feeding, followed by a gradual decrease. In contrast, 13C concentration increased over time in the pericarp and aril of fruits. Translocation of 13C-photosynthates into fruit was high in Sectors 4 and 5, and in top positions (Sectors 7 to 9). At 96 h after 13C feeding, the highest distribution ratio of 13C-photosynthates was observed in stems, followed in descending order by pericarp, leaf, and aril. 13C distribution ratio in the aril was generally highest in fruits from inner and center positions. The relationship between partitioning of photosynthates and quality of mangosteen fruit, which differs among sectors, has been discussed. Keywords: fruiting positions, Garcinia mangostanaL., photosynthate partitioning, 13C, tree branches

Abstract

Boost converter is one of fundamental DC-DC converters and used to deliver electric power with boosted voltage in many electrical systems. Several control strategies have been applied to control a boost converter delivering a constant output voltage. Generally, boost converter works in two modes; one is called a Continuous Conduction Mode (CCM). Many researches use CCM model in the controller design, but they never ensure that the controller always works in CCM. This paper proposes novel nonlinear controller of boost converter designed using the modi?cation of ?ow in phase plane. The proposed controller guarantees that the boost converter works only in CCM region. The simulation result con?rms that our proposed controller brings the state variables from any initial point to a desired operating point successfully.

Abstract

ABSTRACT. The objective of this study is to prepare biocoagulant from shrimp waste for municipal wastewater treatment. Shrimp waste was ground and deproteinized using NaOH solution at 100 ºC for 2 hours, then demineralized using HCl at 80 ºC for 8 hours to form chitin. The chitin was then deacetylized by NaOH solution at varied temperatures of 60-70 ºC for 4 hours of heating to form chitosan. The chitosan was then used as a biocoagulant for municipal wastewater. This study refers to jar test results, where there were parametersto be assessed, such as turbidity decrease (NTU), reduction in heavy metals levels compared to those prior to chitosan addition, pH influence on coagulation, and optimum concentration used as compared to the use of aluminium sulfate. This study revealed that pH 7 was the optimum condition.

Abstract

Teachers are required to have a teaching performance that can improve the quality of education. To achieve the quality of good education and quality, highly influenced teacher's teaching performance in carrying out its duties, so that teacher teaching performance becomes an important demand for educational success. This study reveals about the magnitude of the contribution of pedagogic competence and work motivation to the teaching performance of teachers. This research was conducted on kindergarten teacher Aisyiyah Se Bandung City by way of test to the teacher and spread the questionnaire to 54 kindergarten teacher Aisyiyah in Bandung City. The research findings show that pedagogic competence contribute to teacher's teaching performance of 19.09%. While work motivation contribute to teacher teaching performance of 27.98%. The pedagogic competence and work motivation simultaneously (simultaneously) the contribution to teacher teaching performance of 30.25%. Teachers need to demonstrate better teaching performance by working to improve their pedagogical skills and work motivation in order to improve the quality of education. While the foundation should pay more attention to the role of the teacher, because the task of the teacher is not an easy task. It needs to be appreciated to teachers, so that teachers are more focused and concentrate in their work as professional teachers.

Abstract

Face recognition is one of early detection in security system. Automation encourages implementation of face recognition in robot with low-power processor. Most of face recognition research focused on recognition accuration only and performed on high-speed computer. Face recognition that is implemented on low-cost processor, such as ARM processor, needs proper algorithm. Our research proposed K-Nearest Neighbor (KNN) algorithm to recognize face by ARM processor, which was common processor in robot system. This research sought best k-value to create proper face recognition with low-power processor. The proposed algorithm was tested on AT&T face dataset from Computer Laboratory, Cambridge University. The 15 images were set as testing image and 315 images were used as reference data set. OpenCV was choosen as main core image processing library, due to its high-speed. Proposed algorithm was implemented on ARM11 700MHz. Experiment result showed that KNN face recognition detected 93.3% face with k=1. Another proposed Histogram KNN face recognition gave 100% true detection with k=3. Overall experiment showed that proposed algorithm detected face on 2.657 s by ARM processor.
