Unemployment is caused by the work force or job seekers are not proportional with the number of existing jobs. Unemployment is often a problem in the interconnected economy due to unemployment, productivity and income will be reduced. The number of unemployed in an are a expected to be affected by unemployment in the surrounding area. This is made possible because of the proximity factor or adjacency between regions, it is estimated that there are linkages to the regional unemployment rate. To determine the relationship between regional linkages used Moran's Index method. The number of unemployed in Central Java, obtained Moran's Index value = 0.0614. Moran's Index values in the range 0 < I ≤ 1 indicating the presence of spatial autocorrelation is positive but small correlation can be said because of near zero, orit can be concluded that the similarity between the district does not have a value or indicate that unemployment among districts in Central Java has a small correlation.

Ikan bandeng merupakan bahan makanan yang tinggi akan protein, vitamin dan mineral. Salah satu cara untuk meningkatkan pemasaran adalah mix marketing, salah satunya adalah mix marketing produk. Mix marketing produk yang dapat dilakukan adalah dengan diversifikasi produk. Olahan ikan bandeng yang terkenal adalah di kabupaten Pati.

Dalam binaan tersebut, yang menjadi salah satu program adalah diversifikasi produk UKM Diversifikasi produk yang dilakukan oleh UKM Primadona atas binaan tim pengabdi adalah keripik kulit dan abon duri ikan bandeng. Kulit ikan bandeng merupakan hasil filet dari daging ikan bandeng. Kulit ikan bandeng dicampur dengan tepung beras, tepung tapiokan dan rempah-rempah lainnya untuk diolah menjadi keripik kulit yang renyah. Tekstur keripik kulit ikan bandeng adalah renyah, mempunyai pola sisik ikan. Kandungan protein, vitamin dan mineral keripik kulit ikan bandeng juga cukup tinggi.

Theoretically, the movement of the Composite Stock Price Index (CSPI) is in line with the company’s stock price movements. Hence, it would be appropriate to measure the CSPI contribution to the company’s stock price regarding modeling the company’s stock price. 2-dimensional Geometric Brownian Motion is believed to be the most appropriate model in this case. Therefore, this paper aims to project the share price of PT Telekomunikasi Indonesia in 2018 by considering the CSPI movement. The resulted mean absolute percentage error (MAPE) calculations lead to a conclusion that Prediction with 2-dimensional Geometric Brownian Motion (GBM) is more accurate than the individual modeling of stock prices of PT Telekomunikasi Indonesia. PT Telekomunikasi Indonesia Tbk’s stock price modeling is more appropriately-used by taking heed on the movement of the Composite Stock Price Index. It is conclusive that the two dimensional geometric Brownian motion model provides an accurate prediction of PT Telekomunikasi Indonesia Tbk shares with MAPE is 1.980296%.

The essence of investment is a placement of a number of funds at one time in hope of gaining profits in the future. One of the most traded forms of investment is stocks. When investing in stocks, investors often run the risk of loss. This loss risk can be overcome by forming a portfolio consisting of several shares. To form an optimal portfolio, investors must first determine an efficient portfolio that produces a certain level of profit with the lowest risk, or a certain level of risk with the highest level of profit. One method for determining the optimal portfolio is to use the Single Index Model method. Whereas to calculate Value at Risk (VaR) using the Historical Simulation method. In this study, researcher used data from the daily closing price of shares incorporated in the Jakarta Islamic Index (JII) stock group in the period of June - November 2017. The shares which will be used were 9 shares in the JII stock group. According to the research result, there are three stocks that go into an optimal portfolio that is SMGR, UNTR, and KLBF with the value of each of its shares respectively by 48,54%, 46,18%, and 5,28%. While the value of the Value at Risk with initial capital of Rp100.000.000, 1 day holding period and a trust level of 95% for optimal portfolio and each stock that goes into optimal portfolio amounted Rp2.090.283, Rp2.258.600, Rp3.403.000, and Rp2.564.200. Keywords: Share, Portofolio, Single Index Model, Value at Risk, Historical Simulation, JII.
