This research was conducted based on the increase in society’s enthusiasm towards investing in the capital market, particularly the stock market. New investors’ lack of knowledge about stock may lead them to invest in stocks only based on the return. Return is one of the most important factor in choosing stock to invest in, however it is not the only important factor. Investors should also consider the stock’s risks as well as whether the stock is very high in volatility or not (Shares with high volatility is called “saham gorengan” in Indonesian). The purpose of this research is to find out the differences between optimal portfolio which consists of stocks registered in LQ45 Index and optimal portfolio which consists of stocks unregistered in LQ45 Index within the time frame of 2015-2017. The research method used is t-test to differentiate two means from two independent samples. The finding of this research shows there is a significant difference between optimal portfolio which consists of stocks registered in LQ45 Index and optimal portfolio which consists of stocks unregistered in LQ45 Index within the period of 2015-2017.

Laston AC-WC is the outer layer of the pavement that is directly related to the outside, so a strong mixture is required. One of the major effects is the aggregate gradation.This experiment aims to find out the comparison of Laston AC-WC performance between mixtures used aggregat egradation above and below the restriction zone. Each mixture used 6 variations of asphalt content and there were 3 specimens on each variation of bitumen content. The asphalt contents used were 5,5%; 6%; 6,5%; 7%; 7,5% dan 8%. From the results of the experiments, the mixture with the aggregate above the restriction zone at 7% and 7.5% asphalt content had a density value of 2.13 gr / cc and 2.12 gr / cc respectively; VMA value of 15.49% and 15.91%; VFA values ​​of 80.48% and 79.98%; VIM value of 3.16% and 3.18%; stability value of 3013.58 kg and 2332.57 kg; flow value of 2.47 mm and 2.18 mm; as well as MQ values ​​of 1222.25 kg / mm and 1184.59 kg / mm. While on the mixture with the aggregate under the restriction zone in the asphalt content of 7% and 7.5% obtained density value of 2.11 gr / cc and 2.14 gr / cc; VMA value of 17.21% and 16.3%; VFA value of 71.21% and 78.65%; VIM value of 4.99% and 3.49%; stability value of 2518,75 kg and 3234,72 kg; flow values ​​of 2 mm and 2.07 mm; as well as the MQ value of 1259.37 kg / mm and 1623.54 kg / mm. From the results are analyzed Paired T test and found that the value of flow has a significant difference. The high flow rate was found in the mixture with the aggregate above the restriction zone at 7% asphalt content, so this mixture is more durable due to good flexibility. Laston AC-WC merupakan lapisan terluar perkerasan yang berhubungan langsung dengan keadaan luar, sehingga dibutuhkan campuran yang kuat. Salah satu yang berpengaruh besar adalah gradasi agregat yang digunakan. Penelitian ini bertujuan untuk mengetahui perbandingan kinerja laston AC-WC antara campuran yang menggunakan gradasi di atas dengan di bawah daerah larangan. Penelitian ini dilakukan terhadap campuran laston AC-WC. Masing-masing campuran menggunakan 6 variasi kadar aspal dan terdapat 3 benda uji pada setiap kadar aspal. Kadar aspal yang digunakan adalah 5,5%; 6%; 6,5%; 7%; 7,5% dan 8%. Dari hasil penelitian, campuran dengan agregat di atas daerah larangan pada kadar aspal 7% dan 7,5% memiliki nilai density berturut-turut sebesar 2,13 gr/cc dan 2,12 gr/cc; nilai VMA sebesar 15,49% dan 15,91%; nilai VFA sebesar 80,48% dan 79,98%; nilai VIM sebesar 3,16% dan 3,18%; nilai stabilitas sebesar 3013,58 kg dan 2332,57 kg; nilai flow sebesar 2,47 mm dan 2,18 mm; serta nilai MQ sebesar 1222,25 kg/mm dan 1184,59 kg/mm. Sedangkan pada campuran dengan agregat di bawah daerah larangan pada kadar aspal 7% dan 7,5% didapatkan nilai density sebesar 2,11 gr/cc dan 2,14 gr/cc; nilai VMA sebesar 17,21% dan 16,3%; nilai VFA sebesar 71,21% dan 78,65%; nilai VIM sebesar 4,99% dan 3,49%; nilai stabilitas sebesar 2518,75 kg dan 3234,72 kg; nilai flow sebesar 2 mm dan 2,07 mm; serta nilai MQ sebesar 1259,37 kg/mm dan 1623,54 kg/mm. Dari hasil tersebut dilakukan analisa Uji T Berpasangan dan didapatkan bahwa nilai flow memiliki perbedaan yang signifikan. Nilai flow yang tinggi terdapat pada campuran dengan agregat di atas daerah larangan pada kadar aspal 7%, sehingga campuran ini lebih tahan lama dikarenakan memiliki kelenturan yang baik.

The research method used is a quasi-experiment with population of students of SMK TERPADU HUTAMA and with samples of 68 people simply and randomly taken by using a self-developed instrument in the form of test about Mathematics Learning Outcomes. The research data for the experimental and controlled classes are collected by analyzing the test using t test, while the normality analysis requirement is analyzed by testing with chi-square test and homogeneity with F test. The result of the research shows that there is a significant difference between students’ learning outcomes through constructivism approach and through an open-ended approach to mathematics learning in SMK TERPADU HUTAMA. From the research results, it can be concluded that the constructivism approach is better than the open-ended approach in statistics learning because the former can encourage the development of individual’s skill in the classroom.</em></p>

This study determines the accuracy level of CAPM and APT in determining the expected return of LQ45 and comparing the expected return from CAPM and APT models. This study uses descriptive and comparative research approaches. The population is all stocks listed in the LQ45 index while the sampling method used is purposive sampling with stock criteria that have complete data for the period November 2015 - November 2019. This study uses an independent sample t-test in testing the expected return differences between the CAPM and APT models. The result showed that the CAPM Model was more accurate in determining the expected return of LQ45 stocks compared to the CAPM method. The result also showed that there was a significant difference in expected return between CAPM and APT models. Based on this result, investors can use the CAPM model in predicting the returns of the stock listed on the LQ45. For further research, can use another index in the capital market as a research object, used a longer period to get a more accurate result, and add some more macro variables.
