"ABSTRAKIndeks harga saham merupakan indikator yang menggambarkan pergerakan harga sekelompok saham. Salah satu indeks harga saham yang terdapat di Indonesia adalah IHSG Indeks Harga Saham Gabungan . Terdapat banyak manfaat dari mengikuti pergerakan IHSG, salah satunya untuk meminimalisir kerugian dari berinvestasi dalam pasar saham. Oleh karena itu, akan dilakukan prediksi nilai IHSG. Metode yang akan digunakan adalah ANFIS Adaptive Neuro-Fuzzy Inference System dan SVR Support Vector Regression yang merupakan pengembangan dari metode ANN Artificial Neural Network . Selanjutnya performa keduanya akan dibandingkan. Hasil percobaan menghasilkan SVR sedikit lebih baik dari segi keakuratan dibandingkan ANFIS. Nilai keakuratan dari SVR yaitu 78,35 , 97,93 , dan 98,96 sedangkan keakuratan ANFIS yaitu 77,31 , 96,90 , dan 98,80 masing-masing untuk hasil prediksi yang nilai eror relatifnya di bawah 1 , 2 , dan 3 . Maksimum keakuratan dan running time pada ANFIS bergantung banyaknya hari yang digunakan untuk prediksi. Semakin banyak hari yang digunakan untuk prediksi, maka nilai keakuratannya semakin rendah dan running time semakin lama. Sedangkan maksimum keakuratan dan running time pada SVR tak bergantung pada banyaknya hari yang digunakan untuk prediksi. Dalam skripsi ini disajikan pula hasil sampingan berupa clustering berdasarkan eror relatif hasil prediksi menggunakan FKCM Fuzzy Kernel C-Means . Tujuan dari clustering ini yaitu mengecek apakah hasil prediksi yang dihasilkan ANFIS dan SVR kurang dari suatu nilai eror relatif yang ditetapkan.

ABSTRACTStock index reflects the price movement a group of stock. There are many stock indices in the world. JKSE Jakarta Composite Index is one of stock index in Indonesia. There are many benefits in following JKSE value, one of them to minimize the loss in stock investment. Therefore, JKSE value will be predicted. The method used are ANFIS Adaptive Neuro Fuzzy Inference System and SVR Support Vector Regression which are development of ANN Artificial Neural Network method. The performance of these two method will be compared. The experiment result gives that SVR is slightly better in terms of accuracy than ANFIS. The accuracy values of SVR are 78,35 , 97,93 , dan 98,96 while the accuracy of ANFIS are 77,31 , 96,90 , dan 98,80 each for a predicted result whose relative eror value is below 1 , 2 , dan 3 . The maximum accuracy and running time on ANFIS depend on how many days are used for prediction. The more days used for prediction will give the lower accuracy and longer running time. While the maximum accuracy and running time on SVR does not depend on the number of days used for prediction. In this thesis, presented also clustering based on relative error from the predicted result using FKCM Fuzzy Kernel C Means . The purpose of this clustering is to check whether the prediction result by ANFIS and SVR is less than a relative error value set."

"Penelitian ini mengeksplorasi dampak dari busy directors pada risiko crash harga saham jika individu memegang tiga atau lebih jabatan di dewan. Busy directors merujuk kepada Komisaris karena Indonesia mengadopsi two tier system. Sebagian besar literatur menunjukkan bahwa faktor utama risiko crash harga saham timbul karena adanya kecenderungan manajemen menahan berita buruk dari investor terkait kontrak kompensasi dan masalah karier. Penelitian ini bertujuan untuk memverifikasi apakah busy directors membantu membatasi perilaku oportunistik manajerial. Hasil penelitian menunjukkan bahwa rangkap jabatan tidak memiliki pengaruh pada risiko crash harga saham dikarenakan cross over interaction yang meniadakan pengaruh signifikan terhadap risiko crash harga saham. Sebagai negara yang identik dengan konsentrasi kepemilikan keluarga, hasil menunjukkan bahwa perusahaan keluarga akan memperkuat pengaruh negatif dari Komisaris yang melakukan rangkap jabatan dalam mengurangi risiko crash harga saham. Penelitian ini menggunakan sampel perusahaan yang terdaftar di Indonesia di Bursa Efek Indonesia selama periode 2014-2019. Generalized method of moment (GMM estimator) digunakan sebagai metode penelitian untuk mengurangi masalah endogenitas.

This research explores the impact of busy directors on the risk of stock price crashes if individuals hold three or more directorships. Busy directors refer to the Commissioners because based on two tier system, oversight function is performed by Commissioner. A large body of literature reports that a prominent factor of stock crash risk is the managerial tendency of withholding bad news from investors due to compensation contracts and career concerns. This study aims to verify whether busy directors help restrict these opportunistic managerial behaviors. The results show that the multiple directorship does not have an effect on the risk of stock price crash due to cross over interaction which negates the significant effect on of stock price crash risk. As a country with high family ownership concentration, the result shows that interaction between busy directors and family firms will strengthen the negative effects of Commissioners who hold dual positions in reducing stock price crash risk. This study uses a sample of listed companies in Indonesia on the Indonesia Stock Exchange's main board during the 2014-2019 period. Generalized method of moment (GMM estimator) is used as a research method to reduce endogeneity issues."

"Stock Split is one of popular corporate action in capital market. Stock Split is the split of a company's existing stock into more shares. Each stockholder would receive an additional share for each share formerly held depend on the ratio of the split.

Since investing in the common stock related to the prospect of the company, management must consider and managing the fundamental of the company before making a planning of stock split. Prospective fundamental will support the effectiveness and successfull of the stock split.3. Regarding the decrease of the volume of stock trading, management must aware the the decreasing the value of the stock price, which means management must maintain the appropriate level due to the company's performance. Periodic evaluation of the stock price changes must be scheduled.4. During the study period, researcher find an anomaly due to Signaling Hypothesis Theory.
