This study compares the risks and returns between the two indices in the Indonesian Stock Exchange (IDX), namely the LQ 45 Index and the Jakarta Islamic Index (JII). This research period, starting from January 2008 to December 2017. Based on the normality test, the results obtained that the risk data of the LQ 45 Index are normally distributed while the JII Index risk data is not normally distributed. So that a different test used non-parametric statistics, namely the Mann Whitney test. In this study, the results obtained that there is no significant difference in the risk of the LQ 45 index with the JII index. Whereas based on the normality test for LQ 45 Index return data and JII Index return obtained both data are normally distributed and homogeneous. So that the parametric statistics were used by the T test. And the results obtained that the LQ 45 index return also had no significant difference with the JII index. This is due to almost the same constituents / members of these two indices, or the occurrence of a strong slice between the two. Finally, it can be concluded that the risks and returns between the LQ 45 Index and the JII Index have no significant differences.

Objective: To achieve the excellent levels of athletic performance, professional athletes need to do continuous exercises and strengthen special muscles of the body and have to spend a lot of time training in that sport. As a result, depending on the prevailing condition of each sport, the physical orientation and the degree of abnormalities of the athletes in that sport are affected. Methods: The current study is descriptive and cross-sectional. The statistical population was 12-14 years old boys in middle and high school. The statistical sample of this study included 30 people (13 volleyball players and 17 basketball players) with a targeted training rate of at least three sessions per week. The Chippaux Smirak Index (CSI) method was used to evaluate the arch of the foot and to determine the angles and degrees of kyphosis and lordosis in radiographs. Independent t-test and Mann-Whitney test were used to compare the variables of motor skills and posture by SPSS V. 18 at a significant level of 0.05. Results: The results of independent t-test to compare the variables of motor skills in the two groups of volleyball and basketball show that there is a significant difference between the two groups in the Sargent test and 4mX9m (P=0.000) (P≥0.05). The results were different in strength test (P=0.41) and Sit-up (P=0.75) so that there was no significant difference between the two groups (P≥0.05). The results of Mann-Whitney test to compare posture-related variables showed that there was no significant difference between the two groups in any of the parameters of varus, valgus, pronation, supination, lordosis, kyphosis, foot flat (P≥0.05). Conclusion: The results showed that volleyball players have more impressive and explosive power than basketball players, but in terms of muscle strength and endurance, there is not much difference between these two groups, which is probably due to the nature and specific characteristics of their sports. Therefore, it seems necessary to pay more attention to athletes’ training programs to improve their motor skills and physical condition. In this study, the behavior and common habits of the subjects in interaction with the environment and hereditary characteristics have not been studied, so more research is needed in the etiology of musculoskeletal abnormalities.

Intelligence for young children is very important for themselves and their social development, because if the intelligence of children develops well, it will be easier for them to get along with creating new things. Besides learning media has a very important role in the learning process. Media that can improve mathematical logical intelligence in children, one of them is the dice numbers. Based on observations shows that the logical-mathematical intelligence of students is still low. This study uses a quasi-experimental method using a non-equivalent control group design. Based on the calculation of the experimental class normality test that is 0.044 <0.05, so the data are declared not normally distributed. While in the control class the result is 0.200> 0.05, until the data are declared normally distributed. Therefore, because one class is declared not normally distributed, the data will be processed using the Mann Whitney test. The results of the Mann Whitney test in the experimental and control classes were 0.001 <0.05. So the conclusion is dice media can improve mathematical logical intelligence.Kecerdasan untuk anak usia dini sangat berperan penting bagi dirinya maupun perkembangan sosialnya, karena jika kecerdasan anak berkembang dengan baik maka akan memudahkan mereka bergaul juga menciptakan hal-hal baru. Selain itu media pembelajaran memiliki peranan sangat penting pada  proses belajar. Media yang dapat meningkatkan kecerdasan logis matematis pada anak, salah satunya yaitu dadu angka. Berdasarkan hasil observasi, kecerdasan logis-matematis peserta didik masih tergolong rendah. Penelitian ini memakai metode kuasi eksperimen serta memakai desain kelompok kontrol non-ekuivalen (the nonequivalent control group design). Berdasarkan perhitungan uji normalitas kelas eksperimen yakni 0.044 < 0.05, sehingga data dinyatakan tidak berdistribusi normal. Sedangkan di kelas kontrol hasilnya adalah 0.200 > 0.05, hingga data dinyatakan berdistribusi normal. Oleh sebab itu karena salah satu kelas dinyatakan tidak berdistribusi normal, data akan diolah memakai uji Mann Whitney. Hasil dari postes Mann whitney di kelas eksperimen serta kontrol adalah 0.001 <  0.05. Jadi kesimpulannya media dadu angka dapat meningkatkan kecerdasan logis matematis.

Abstract: Obesity might cause dyslipidemia, marked by increased cholesterol, triglycerides, and LDL levels, as well as reduced HDL level. Dyslipidemia is related to atherosclerosis that can result in cardiovascular diseases. This study was aimed to identify differences of lipid profiles in obese and non-obese teenagers at West Bolangitang, North Bolaang Mongondow. This was an observational analytical study with a cross sectional design conducted from October to November 2016. Subjects were 60 teenagers obtained by using consecutive sampling method and were divided into two groups: obese (29 teenagers) and non-obese (31 teenagers). Lipid profile examinations were performed on all of them. Statistical analysis of total cholesterol level of the two groups used independent t test (p=0.002) dan Pearson correlation test (p=0.028). The normality test of triglyseride level showed that data were not normally distributed, therefore, the analysis was continued with Mann-Whitney test (p=0.328) and Spearman correlation test (p=0.542). The normality test of LDL level showed that data were not normally distributed, therefore, the analysis was continued with Mann-Whitney test (p=0.004) and Spearman correlation test (p=0.032). The normality test of HDL level showed that data were not normally distributed, therefore, the analysis was continued with Mann-Whitney test (p=0.063) and Spearman correlation test (p=0.054). Conclusion: There were significant differences of total cholesterol and LDL levels but there were no significant differences of triglyceride and HDL levels between obese teenagers and non-obese teenagers.Keywords: lipid profile, adolescents, obesity. Abstrak: Obesitas dapat menyebabkan peningkatan lipid kolesterol, trigliserida, maupun LDL dan penurunan lipid HDL yang disebut dislipidemia.

Purpose Building information modeling (BIM) inclusion in education pedagogy is crucial in preparing skilled graduates for employment in the construction industry. Against this backdrop, studies on BIM education abound in architecture, engineering and construction (AEC) programmes in higher education institutions (HEIs). However, there are limited empirical studies on BIM potentials in the quantity surveying (QS) profession in HEIs, particularly in developing countries. The purpose of this study is to identify and assess the BIM drivers and benefits as important to the QS profession using an empirical approach. Design/methodology/approach A comprehensive literature review was conducted to identify the BIM drivers and benefits in relation to the QS profession, which was used to design a questionnaire. To capture a broad perception, a questionnaire survey was carried out which targeted the academia and final year undergraduate students from two selected universities offering QS honour degree programmes in Nigeria. Data collected were analysed using mean score, standard deviation and Mann–Whitney test. Findings The study identified 12 BIM drivers in relation to the QS profession and the analysis of the ranking revealed that almost all the identified BIM drivers are considered by respondents as important. The study further identified 14 BIM benefits and the analysis of the ranking indicated that all the identified BIM benefits are considered as important. The results of the Mann–Whitney test indicated a slight statistically significant difference, particularly in one of the selected universities on the ranking of the BIM drivers and benefits as important to the QS profession. Practical implication The findings of the study provide empirical evidence on the current perceptions of the drivers and benefits of BIM to QS academia and students as they explore the concept for the advancement of QS profession. Originality/value This study would provide practical insights to use BIM for QS practice. Also, this study would contribute to improving the QS graduates and professional quantity surveyors understanding of the BIM knowledge applicable to QS profession.
