Exercise induces profound changes in the renal hemodynamics and protein excretion. Ureum and creatinine levels can be used to assess whether renal function is still working properly or not. Ureum and creatinine levels can be affected by physical activity because ureum and creatinine are products of protein metabolism in skeletal muscle. The purpose of this study was to see the effect of moderate intensity physical activity on ureum and creatinine serum in untrained male students. This research is a preexperimental study with the design of one group pretest-posttest. The sample in this study were ten untrained male students taken by purposive sampling. Physical activity protocol is running on a treadmill for 60 minutes with an intensity of 60-75 percent of maximum heart rate reserve (MHR). Blood samples were taken to measure ureum and creatinine before and after the physical activity. Data were analyzed by paired T-test and Wilcoxon test. This study showed that the average results of ureum had a significant decrease and mean results of creatinine showed a significant increase. Based on these results we can conclude that the moderate intensity of physical activity on a treadmill reduces ureum and increases creatinine in untrained male students.

Indonesian educational community has been focusing on character education recently. Character is usually cultivated upon a set of assumed values that is embraced in one’s social environment. This set of values closely related to awareness of ethical values and social relational system in society. Ethical consideration emerges upon the existence of others. The question is if we need to cultivate ethical awareness and consideration then how can we approach this ethical consideration in mathematics education. The researchers team believe that there are valuesin mathematics itself moreover in mathematics education. With this kind of assumption the researchers team are called to find a way to cultivate students’ ethical awareness through learning activities. According to some research one possible way for this purpose is the use of ethical dilemma problems. Dilemma occurred in a proposed problem will push a person to consider ethical values before making a decision. Hence, this article aims to describe the possibility of using such ethical dilemma problem in mathematics lecture to cultivate students’ ethical awareness. The research described in this article using critical interpretivism paradigm and represented in a narrative inquiry method.

Research has been conducted on the antibacterial activity analysis of Zanthoxylum acanthopodium DC extract on Bacillus subtilis, Salmonella typhi using disc diffusion method. This study aims to determine the ability of Zanthoxylum acanthopodium DC extract in inhibiting the growth of Bacillus subtillis, and Salmonella typhi. Zanthoxylum acanthopodium DC was extracted by maceration method using 96% ethanol. In this extraction process, phytochemical test was carried out to find out the secondary metabolite content in Zanthoxylum acanthopodium DC. Phytochemical test indicate Zanthoxylum acanthopodium DC contained alkaloids, tannins, saponins, and steroids. Antibacterial activity analysis were measured in three concentrations of 25%, 50%, 75%. The best antibacterial activity was observed on Salmonella typhi bacteria with 75% extract concentration which produced a clear zone diameter of 19 mm and 20 mm.

The study aim to examine (1) The relationship directly of the anxiety to sport performance in competitive male’s karateka kumite, (2) The relationship directly of the aggressivity to sport performance in competitive male’s karateka kumite, (3) The relationship Indirect of the anxiety to sport performance in competitive male’s karateka kumite. One hundred and three males karateka kumite (20 ± 2 years) participated in this study. Karateka were taken in Kejuaraan Nasional Antar Mahasiswa Sebelas Maret Cup VII in Surakarta. The research of methodology is the correlation descriptive. The results of study are (1) there is the relationship directly between the anxiety to sport performance in competitive male’s karateka kumite. (2) there is the relationship directly between the aggressivity to sport performance in competitive male’s karateka kumite. (3) there is the relationship indirectly between the anxiety to sport performance in competitive male’s karateka kumite. The conclusion of this study, to achieve the anxiety and aggresivity exercises. Thus, hopefully the male karateka kumite can able to develop aggresivity and to control the behaviour of themself.
本研究旨在探讨(1)焦虑与竞技男子空手道格斗运动成绩的直接关系;(2)攻击性与竞技男子空手道格斗运动成绩的直接关系;(3)焦虑与竞技男子空手道格斗运动成绩的间接关系。103名男性空手道跆拳道选手(20±2岁)参加了本研究。空手道选手是在雅加达举行的第七届Kejuaraan national Antar Mahasiswa Sebelas市场杯上拍摄的。方法论的研究是相关描述性的。研究结果表明:(1)竞技男子空手道搏击运动员焦虑与运动成绩之间存在直接关系。(2)男子空手道搏击竞技运动员的攻击性与竞技成绩之间存在直接关系。(3)男子空手道搏击竞技焦虑与竞技成绩之间存在间接关系。本研究的结论，实现了焦虑与攻击性的锻炼。因此，希望男性空手道选手能够发展出攻击性并控制自己的行为。
