Gold is an investment that has the smallest risk compared to other investment methods, but every time the price of gold always fluctuates. This fluctuation will make it difficult for investors, the government, or those who need gold price data to see how the prospects for gold investment are going forward. To overcome this, a prediction or forecast is made. One of the forecasting methods developed with fuzzy theory is the Saxena-Easo fuzzy time series method. In this study, this method will be used to predict gold prices in the period 17 August 2021 to 31 December 2021. The purpose of this study is to determine the value of gold prices for the period 17 August 2021 to 31 December 2021 and to determine the accuracy of the fuzzy time series method. Saxena Easo. While the parameter used to measure forecasting accuracy is MAPE, if this parameter is in the range of 10% to 20% then the forecasting result is good, and if the parameter is below 10% then the forecast result is very good. The results of forecasting gold prices in the period 17 August – 31 December 2021 have a value that tends to increase and the MAPE obtained is 0.024277%. Therefore, it can be said that the prediction results for certain parameters are very good.

Fertility is the result of real reproduction (live-born babies) from a woman or a group of women or the number of children that will be born by a woman during her reproductive period. Children born to a woman have 2 categories in the BKKBN, namely the number of children > 2 and the number of children 2. The fertility/birth rate by the number of children > 2 reaches 60.9%, so it is not following the BKKBN target because the target birth rate > 30% is included in the category tall. One of the efforts to control the fertility rate is by using contraception. A contraceptive device is a tool or method to prevent pregnancy. The existence of contraceptives but the fertility rate is still high So it is necessary to do targeting (targeting) with the CHAID (Chi-square Automatic Interaction Detection) method. This method is used for targeting and knowing which contraceptives are the most significant, effective, and have the strongest influence on fertility levels to launch BKKBN targeting efforts in seeking population control. The result of the largest Chi-square test is female sterilization, which is 28.624. From the data, it can be concluded that the fertility rate/number of children 2 or >2 is mostly affected by the use of female sterilization contraceptives, and female sterilization is the most effective contraceptive method. This tool can help BKKBN in achieving the target.

Abstract: The Human Development Index is one of the important indicators to illustrate the level of success of a region in trying to build the quality of its population in terms of health, education and others. On the island of Sumatra out of 10 provinces, the Human Development Index in North Sumatra Province is still far behind when compared to Riau Islands Province. This is due to the lack of government role in improving human development in a region. The purpose of this study is to determine the prediction results of the Human Development Index value in North Sumatra Province using the Ensemble K-Nearest Neighbor method and see how much accuracy the Ensemble K-Nearest Neighbor method has to predict the Human Development Index. One method that can be used in predicting the Human Development Index is the Ensemble K-Nearest Neighbor method. K-Nearest Neighbor is a method that determines the label (class) based on distance. To optimize the performance of the K-NN method in making predictions, ensemble techniques are needed. Based on the research conducted, the prediction results obtained using the K-Nearest Neighbor Ensemble method have an average of 72.97 with a MAPE value of 2.1%, which is much better when compared to only using the Single K-NN method which has a MAPE value of 2.38%. Abstrak: Indeks Pembangunan Manusia adalah salah satu indikator penting untuk menggambarkan tingkat keberhasilan suatu daerah dalam usaha membangun kualitas penduduknya baik dari segi kesehatan, pendidikan maupun lainnya. Di pulau Sumatera dari 10 provinsi yang ada, Indeks Pembangunan Manusia di Provinsi Sumatera Utara masih jauh tertinggal jika dibandingkan dengan Provinsi Kepulauan Riau. Hal demikian diakibatkan masih kurangnya peran pemerintah dalam meningkatkan pembangunan manusia disuatu daerah. Tujuan dari penelitian ini yaitu untuk mengetahui hasil prediksi nilai Indeks Pembangunan Manusia di Provinsi Sumatera Utara menggunakan metode Ensemble K-Nearest Neighbor serta melihat seberapa besar tingkat akurasi metode Ensemble K-Nearest Neighbor untuk memprediksi Indeks Pembangunan Manusia. Salah satu metode yang dapat digunakan dalam memprediksi Indeks Pembangunan Manusia adalah metode Ensemble K-Nearest Neighbor. K-Nearest Neighbor adalah salah satu metode yang menentukan label (class) berdasarkan jarak. Untuk mengoptimalkan kinerja metode K-NN dalam melakukan prediksi diperlukan teknik ensemble. Berdasarkan penelitian yang dilakukan maka diperoleh hasil prediksi menggunakan metode Ensemble K-Nearest Neighbor memiliki rata-rata sebesar 72,97 dengan nilai MAPE 2,1% hal tersebut jauh lebih baik jika dibandingkan hanya menggunakan metode K-NN Tunggal yang memiliki nilai MAPE sebesar 2,38%.
