Abstract

Multiple linear regression said to be good if it statistic theassumptions such as: normality assumption, heteroskedastisity, an errordoes not undergo autocorrelation and not occour multicolinearity. On theassumption that problem often arise in the multiple linear regressionassumptions are not fulfilled multicolinearity. Multicollinearity is acondition in which the data of the observations of the independent variablesoccuror have a relationship that is likely to be high. This study aimed tocompare the appropriate method to over come multicollinearity betweenridge regression and principal component analysis. Comparison criteriaused both methods, the mean square error (MSE) and the coefficient ofdetermination (R2), from the data is the simulation with Microsoft Excelthen the analysis was performed, in order to obtain the data first using ridgeregression has a value of MSE of 0.02405 and R2 of 82.4%, while theprincipal component analysis MSE value of 14.14 and R2of 37.5% while thedata second using ridge regression MSE has a value of 0.00216 and R2 of96.9%, while the principal component analysis MSE values of 5.15 and R2 of69.5%. From these results it can be concluded that ridge regression methodis better used.

Abstract

Penelitian ini membahas mengenai perubahan bentuk penataanpermukiman di daerah tersebut yang awalnya terbentuk karena adanyaperbedaan strata kebangsawanan yang terjadi, namun dengan seiringnyaperkembangan zaman dan perubahan bentuk pemerintahan, sehinggapenataan permukiman pada daerah tersebutpun terjadi pergeseran atauperubahan.Tujuan penulisan karya ilmiah ini adalah untuk memberitahukankepada masyarakat bahwa strata kebangsawanan dapat mempengaruhipenataan permukiman suatu daerah, utamanya pada daerah yang masihkuat akan unsurkebangsawanan seperti di Sulawei Selatan contohnya di Kel.Bonto-Bonto Kec.Ma’rang Kab.Pangkep.Fenomena ini masih terlihat jelashingga sekarang, dimana seringkali kita menemukan beberapa nama orangyang menggunakan Andi dan Daeng sebagai gelar bangsawan dariketurunannya. Metode penelitian yang digunakan dalam penulisan karyailmiah ini adalah kualitatif dengan cara melakukan wawancara secaralangsung kepada narasumber atau ahli sejarah di daerah tersebut,kemudian melakukan studi kepustakaan dengan mengumpulkan data danpencarian informasi melalui referensi literatureserta dengan menggunakanteknologi software ArcGIS untuk mengetahui perubahan bentuk kawasanbaik pada masa dulu maupun yang sekarang. Berdasarkan hasil penelitian,kami mengetahui bahwa unsur kebangsawanan di Kel. Bonto-Bonto Kec.Ma’rang Kab.Pangkep ternyata sudah mulai terkikis karena semakinberkembangnya zaman dan karena berubahnya bentuk pemerintahan padadaerah tersebut, yang dulunya menggunakan bentuk pemerintahan kerajaankemudian berubah menjadi bentuk pemerintahan liberal seperti sekarangini.

Abstract

Rubber is the commodity of the results of demand levels andagricultural production always has increased significantly from time to time.This is due to the high demand of the company's suppliers are the result ofprocessed rubber to meet the needs of production. However, due to theinfluence of the conditions of the global economy so that it appears theinstability of prices. The data used in this research in the form of aUnivariate time series data is converted into the multivariate. The methodused is the method of Back propagation Neural Network (BPNN) is appliedto the data time series technical specific rubber commodity prices with thehelp of weighted optimization Particle Swarm Optimization (PSO) whichhopefully may help to improve the performance of the prediction so thatresults of the RMSE for the prediction of rubber prices gained can be moreaccurate. Of research results obtained the best model on a back propagationneural network with the parameters for the training cycle 600, the learningrate and momentum 0.1 0.2, as well as neuron size 3 whereas in particleswarm optimization value of population size 8, max value. of generation 100,the value of inertia weight 0.3, the value of the local best weight 1.0 andglobal best value weight of 1.0 produces a better RMSE value i.e. 0.040compared to just using the BPNN alone i.e. 0043. This proves that the PSOmethod able to give better results.
