Red Guava Leaf Harvesting Impact on Flavonoid Optimation in Different Growth Phases
SANDRA ARIFIN AZIZ,MUNIF GHULAMAHDI
HAYATI Journal of Biosciences , 2011,
Abstract: Harvesting process is a critical time to identify the quality of raw material for traditional medicine. The time and harvesting techniques, drying process after harvesting, and processing to make the simplicia, are the crucial role to make the good quality of the natural product. On the other hand, there is a lack of general understanding and appreciation about the processes involved in governing shoot and tree growth and development, i.e. red guava. The research objective was to evaluate the influence of leaf harvesting and growth phases on red guava for flavonoid production as antioxidant. Randomized factorial block design in time were laid out with two factors and followed by Duncan’s multiple range test. The treatments were the amount of leaf harvested on tertiary branches (0, 25, 50, and 100%) and growth phases of the plant (vegetative and generative). Leaf harvesting 25% on tertiary branches significantly increased the leaf number (766.3 tree-1) and the number of new quarternary branches, decreasing leaf area index (LAI) and leaf dry weight at the end of the experiment (22 weeks of observation/WO). The highest leaf dry weight (156.94 g tree-1) and LAI (0.47) was found in harvesting 25% tertiary branches. Harvesting 100% leaf on tertiary branches in vegetative phase significantly produced the lowest flavonoid production (7.82 g tree-1). The result suggested that flavonoid production from red guava leaves should be done by harvesting 50% leaf on tertiary branches in generative phase can be used to produce the highest flavonoid (89.90 g tree-1).

Abstract:
Torbangun is a folk herb that has been used especially as a breast milk stimulant in North Sumatra, Indonesia. Plant bioactive compound composition is influenced by many factors such as genotype, geographical origin, and environment. Therefore, identifying plant clones with superior chemical composition is a necessity for optimal large-scale production. In this study, three clones of torbangun (hereafter referred to as A, B, and C clones) were analyzed through their phenotypic and foliar phenolic characteristics. The phenotypic results showed that the A clone was distinct from the B and C clones. Nevertheless, the result of multivariate analysis using phenolic data showed that these three clones had three distinct patterns of phenolic compounds. The B clone torbangun was identified as the best clone to be used in larger production scale due to its highest quantity of most phenolic compounds.

Abstract: Waterleaf (Talinum triangulare (Jacq.) Willd has long been eaten in Indonesia as vegetable and the main parts consumed are leaves and young shoots. Waterleaf is sticky presumably due to its pectin content which is associated to dietary fiber. The dietary fiber which was analyzed in the present study was influenced by cultivation practices. The aim of this research was to study the effect of organic and conventional fertilization as well as the seasonal changes to the level of TDF (total dietary fiber), IDF (insoluble dietary fiber), SDF (soluble dietary fiber), and pectic substances in waterleaf. This research was conducted in four phases: sample cultivation, sample preparation, chemical analysis, and data analysis. This research used five samples cultivated with 5 different compositions of organic fertilizers and vice versa for conventional fertilizers. The cultivation was done in the experimental field of University Farm, Bogor, Indonesia during rainy season and dry season. Samples were harvested 8 weeks after planted, dried using drying oven for 17 hours at 60°C, ground and filtered to 40 mesh; and kept at -10°C until analysis. The overall result showed that the conventional samples contain higher dietary fiber than the organically fertilized samples, except the pectic substances of plant in dry season. Although its IDF content is higher than the SDF, the SDF content of waterleaf is relatively high compared to other vegetables, especially in dry season.

Abstract: Introduction: A psychoactive substance has become an overwhelming public health burden globally. It causes social problems for the user and surrounding people which may affect work or study and cause negative economic impact. Objective: This study aims to translate and culturally adapt the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) into Malay and to assess its reliability and validity. Methods: The Malay version of the ASSIST v 3.1 was developed after the translation and back-translation, which included the stages recommended by Beaton. The ASSIST v 3.1 was administered to 125 respondents. The Malay ASSIST v 3.1 was completed twice by each respondent 7 to 14-day intervals to assess test-retest reliability based on the intra-rater and interrater correlation coefficient. Results: Majority of the respondents were male, Malay and currently employed. The intra-rater reliability is 0.84 and the test-retest reliability (ICC = 0.97) were excellent. Conclusion: Malay ASSIST v3.1 was a valid and reliable tool to screen substances abuse at varying degree. Nonetheless, further studies are needed to assess its responsiveness.

Research Journal of Applied Sciences , 2012, DOI: 10.3923/rjasci.2010.165.171
Abstract: This research studied students perception and awareness on occupational safety and health management in residential college. To achieve this objective, Ibrahim Yaakob College (KIY), University Kebangsaan Malaysia was chosen as a case study. Even though safety and health management aspects has been implemented through out the university, there are possibilities that students are exposed to certain types of accident and injuries. Therefore, it is important to carry out this study in order to ascertain to what extent the level of safety and health awareness among students at KIY. About 129 respondents were chosen among students who stayed at KIY. Pearson correlation method was employed to analyze the data. The result showed that various perceptions were given by respondents in relation to management level and occupational safety and health procedure at KIY. The study also found that there was a significant relationship between demographic factors and occupational safety and health training. Furthermore, the university should pay more attention to the aspects of safety and health management especially among residential college occupants, thus the welfare of the student can be managed properly.

BMC Medical Genetics , 2012, DOI: 10.1186/1471-2350-13-89
Abstract: Background There is evidence that one of the key type 2 diabetes (T2D) loci identified by GWAS exerts its influence early on in life through its impact on pediatric BMI. This locus on 10q23 harbors three genes, encoding hematopoietically expressed homeobox (HHEX), insulin-degrading enzyme (IDE) and kinesin family member 11 (KIF11), respectively. Methods We analyzed the impact of adipogeneis on the mRNA and protein expression levels of these genes in the human adipocyte Simpson-Golabi-Behmel syndrome (SGBS) cell line in order to investigate which could be the culprit gene(s) in this region of linkage disequilibrium. Results Following activation of differentiation with a PPARγ ligand, we observed ~20% decrease in IDE, ~40% decrease in HHEX and in excess of 80% decrease in KIF11 mRNA levels when comparing the adipocyte and pre-adipocyte states. We also observed decreases in KIF11 and IDE protein levels, but conversely we observed a dramatic increase in HHEX protein levels. Subsequent time course experiments revealed some marked changes in expression as early as three hours after activation of differentiation. Conclusion Our data suggest that the expression of all three genes at this locus are impacted during SGBS adipogenesis and provides insights in to the possible mechanisms of how the genes at this 10q23 locus could influence both adipocyte differentiation and susceptibility to T2D through insulin resistance.
Some Games Used to Teach Vocabulary to Young Learners

TEFLIN Journal , 2003,
Abstract: Many English classes in Indonesia are now filled with many young learners. For example, a class may consist of 25 - 30 students. As a result, this may not be effective. The students could feel bored, stuck, and noisy, furthermore, if the class is filled by many young learners the atmosphere cannot be supportive anymore. To overcome the problem, the English teacher can vary his/her teaching techniques, one of which is playing games. They can undoubtedly, entertain the students Wierus and Wierus (1994:218) said that in easy, relaxed atmosphere which is created by using games, students remember things faster and better. This paper discusses the benefit of using games, the approriacy of using games, and some current games to teach vocabulary.
SUPPLY-CHAIN OF NATURAL RUBBER IN INDONESIA

Jurnal Manajemen & Agribisnis , 2005,
Abstract: The study examines the supply chain of natural rubber production in Indonesia and assessing the transmission of prices to rubber growers and provides recommendations for a suitable scheme that would help to ensure high production standards and a sustainable return for natural rubber production. The frameworks to examine the performance of supply chain of rubber marketing rely mostly on the efficiency level of marketing system of natural rubbers, including the value chain principles in marketing margin, and revealed price transmission from consumers to growers. The results show that the roles of subdistrict middlemen are extremely crucial in moving up the slabs from the village level to urban areas, where trader-brokers are expecting the slabs to be forwarded directly to crumb-rubber factories. Changes in world price, hence the profits being accumulated by traders and rubber factories, are not transmitted properly to rubber farmers and/or sharetappers. Information asymmetry, the access over price information, and immediate response of rubber growers to the change in world price could explain this non-cointegration in price data between growers and exporters. In the near future, the policy reforms in supply chain of natural rubber marketing in Indonesia should carefully address these issues in a more comprehensive manner. Finally, in order to contribute to the positive environmental and social benefits, the major challenge for natural rubber production system in the future is how to integrate a high productivity promotion of new clonal rubber varieties and a decision for land use practices that satisfy sustainable resource management and ensure acceptable quality of environments in the forest margin.
