PEMODELAN RETURN HARGA SAHAM MENGGUNAKAN MODEL INTERVENSI–ARCH/GARCH (Studi Kasus : Return Harga Saham PT Bayan Resources Tbk)
Authors: Widodo Dea Manuella , Sudarno Sudarno , Hoyyi Abdul
Published: September 2020

The intervention method is a time series model which could be used to model data with extreme fluctuation whether up or down. Stock price return tend to have extreme fluctuation which is caused by internal or external factors. There are two kinds of intervention function; a step function and a pulse function. A step function is used for a long-term intervention, while a pulse function is used for a short-term intervention. Modelling a time series data needs to satisfy the homoscedasticity assumptions (variance of residual is homogeneous).  In reality, stock price return has a high volatility, in other words it has a non-constant variance of residuals (heteroscedasticity). ARCH (Autoregressive Conditional Heteroscedasticity) or GARCH (Generalized Autoregressive Conditional Heteroscedasticity) can be used to model data with heteroscedasticity. The data used is stock price return from August 2008 until September 2018. From the stock price return data plot is found an extreme fluctuation in September 2017 (T=110) that is suspected as a pulse function. The best model uses the intervention pulse function is ARMA([1,4],0) (b=0, s=1, r=1). The intervention model has a non-constant variance or there is an ARCH effect. The best variance model obtained is ARMA([1,4],0)(b=0, s=1, r=1)–GARCH(1,1) with the AIC value is -205,75088. Keywords: Stock Return, Intervention, Heteroscedasticity, ARCH/GARCH

Multiple Linear Regression can be solved by using the Ordinary Least Squares (OLS). Some classic assumptions must be fulfilled namely normality, homoskedasticity, non-multicollinearity, and non-autocorrelation. However, violations of assumptions can occur due to outliers so the estimator obtained is biased and inefficient. In statistics, robust regression is one of method can be used to deal with outliers. Robust regression has several estimators, one of them is Scale estimator (S-estimator) used in this research. Case for this reasearch is fish production per district / city in Central Java in 2015-2016 which is influenced by the number of fishermen, number of vessels, number of trips, number of fishing units, and number of households / fishing companies. Approximate estimation with the Ordinary Least Squares occur in violation of the assumptions of normality, autocorrelation and homoskedasticity this occurs because there are outliers. Based on the t- test at 5% significance level can be concluded that several predictor variables there are the number of fishermen, the number of ships, the number of trips and the number of fishing units have a significant effect on the variables of fish production. The influence value of predictor variables to fish production is 88,006% and MSE value is 7109,519. GUI Matlab is program for robust regression for S-estimator to make it easier for users to do calculations. Keywords: Ordinary Least Squares (OLS), Outliers, Robust Regression, Fish Production, GUI Matlab.

Authors: Sulayman Abdulhakim , Djamiatun Kis - , Muniroh Muflihatul
Published: September 2020

ABSTRACTBackground: Malaria, caused by Plasmodium sp infection, is a major global cause of morbidity and mortality. Most experimental cerebral malaria (ECM) studies show increase number of Th1 cells and CTLs in the brain, due to increase chemokine expression, including CXCL10, a potent chemokine involved in cerebral malaria (CM). Recent studies show that CXCL10 provokes apoptosis of human brain micro-endothelial cells and in vitro neuroglia cells.Objective: To determine whether combination of Annona muricata-leaf-extracted-by-water (AME) and artemisinin-combination-therapy (ACT) reduce brain-CXCL10-expression of Swiss-mice inoculated with P. berghei ANKA (PbA). Methods: This was an experimental-study with post-test-only-control-group-design. Twenty-four Swiss-mice (PbA-inoculated) were randomly divided into 4 groups. Control group (C) was PbA inoculated only. X1, X2 and X3 groups received AME, ACT and combination of AME and ACT treatment, respectively.  CXCL10 was stained with in immunohistochemistry, which then observed by light microscope in order to determine Allred-score. Kruskal-Wallis test was used to statistically analyze the differences among groups, then followed by a Mann- Whitney U test.Result: C and X1groups had severe-PbA-infection when the study was end on day-7-PbA-infection, while X2 and X3 groups entered recovery-stage. The AME-ACT-treatment-group had significantly lower of brain-CXCL10-expression than AME-group (p=0.008) and nearly significantly lower than control-group (p=0.058). Group that received ACT alone had no different value of brain-CXCL10-expression than control-group (p=0.502) and combination AME–ACT group (p=0.335).Conclusion: The combination of AME–ACT treatment decreases brain-CXCL10-expression of Swiss-mice during PbA-infection-recovery-stage, indicating the effectivity of AME–ACT combined therapy is better prevention of cerebral malaria than AME alone.

Deterjen dapat memberikan dampak negatif terhadap proses kehidupan organisme di dalamnya, salah satunya proses penetasan telur ikan. Fase telur merupakan stadia yang rentan dan jauh lebih sensitif terkena pengaruh dari luar atau dari lingkungan. Berdasarkan hal tersebut, diperlukan adanya masukan mengenai dampak surfaktan terhadap daya tetas telur ikan karper (C. carpio). Tujuan penelitian ini adalah menentukan nilai LC50-96 jam dari deterjen berbahan aktif surfaktan jenis NA-ABS, dan mengetahui pengaruh kandungan surfaktan terhadap daya tetas telur ikan karper (C. carpio). Materi yang digunakan dalam penelitian ini adalah ikan karper (C. carpio) dan telurnya. Metode yang digunakan dalam penelitian ini adalah eksperimental laboratoris. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan yang terdiri dari 3 ulangan. Tahap penelitian terdiri dari: uji pendahuluan, uji lanjut, Persiapan materi telur ikan, uji utama, perhitungan daya tetas telur, dan pengukuran variabel kualitas air. Perlakuan yang diberikan pada uji utama adalah pemberian deterjen terhadap telur ikan dengan konsentrasi 6,25%, 12,5%, 25%, 50%, dan 100% dari nilai LC50-96 jam, yaitu 1,35 mg/L, 2,70 mg/L, 5,40 mg/L, 10,80 mg/L, dan 21,60 mg/L. Hasil penelitian menunjukkan bahwa nilai LC50-96 jam surfaktan terhadap ikan karper (C. carpio) adalah 21,60 mg/L. Kualitas air selama penelitian, yaitu: suhu 24,37 – 28,30oC, oksigen terlarut 2,37 – 4,00 mg/L, dan pH 7. Hasil analisis data menggunakan ANOVA faktorial menunjukkan bahwa konsentrasi deterjen berpengaruh nyata terhadap daya tetas telur ikan karper (p<0,05), semakin besar konsentrasi deterjen maka persentase daya tetas telur setiap harinya semakin kecil. Pengaruh deterjen mulai terlihat jelas pada konsentrasi 5,40 mg/L dengan waktu kritis yaitu pada hari kedua.
