Abstract

Metode AMMI (Additive Main Effects and Multiplicative Interaction) adalah suatu metode analisis yang menggabungkan pengaruh utama aditif pada analisis ragam dengan penguraian bilinear pengaruh interaksi ganda. Dalam berbagai penelitian agronomi metode ini mampu menjelaskan lebih efektif pengaruh dan pola struktur interaksi antara genotip dengan lingkungan. Metode AMMI dapat diterapkan pada model campuran jika pengaruh acak pada faktor interaksi dipandang sebagai pengaruh tetap. Sebagai ilustrasi penerapan, penelitian ini menggunakan data produksi padi gogo (ton per hektar) dari hasil percobaan multi lingkungan.

Abstract

Metode klasifikasi berstruktur pohon mulai banyak digunakan di berbagai bidang terutama karena hasilnya yang mudah diinterpretasikan. Tulisan ini mengangkat CRUISE sebagai metode pohon klasifikasi yang relatif baru, serta membandingkannya dengan dua metode serupa yang telah dikenal sebelumnya, yaitu CHAID dan QUEST. Data jamur tingkat tinggi (mushroom) genus Agaricus dan Lepiota digunakan untuk penerapan empat metode (CRUISE 1D, CRUISE 2D, QUEST, dan CHAID). Analisis keempat metode tersebut menunjukkan bahwa peubah-peubah yang palingberkaitan dengan klasifikasi jamur yang ‘dapat dimakan’ atau ‘beracun’ adalah aroma dan warna sporanya. Untuk kasus ini, tampaknya CRUISE merupakan metode yang paling baik, dengan salah klasifikasi 0.0000 dan menghasilkan pohonterkecil. Berdasarkan metode ini, jamur yang dapat dimakan adalah jamur beraroma almond, adas, atau tidak beraroma, memiliki warna spora selain hijau, serta tidak ditemui secara bergerombol. Identifikasi jamur demikian cukup mendapat dukungan dari segi mikologi. QUEST dan CHAID masing-masing menghasilkan salah klasifikasi 0.0014 dan 0.0028. Dari segi kecepatan proses, CRUISE 1D adalah yang tercepat. QUEST sedikit lebih lambat daripada CRUISE 1D untuk data berukuran besar dan peubah kategorik yang banyak, sedangkan CRUISE 2D memerlukan waktu pemrosesan (CPU time) paling lama. Dengan salah klasifikasi yang relatif kecil dan pohon yang pendek, CRUISE dapat menjadi alternatif yang baik bagi metode klasifikasi lainnya.

Abstract

Since decentralisation was implemented in Indonesia, more detailed information about the condition of an area becomes very necessary to know as an evaluation of development that the government has done. the success development of a region can be seen through the Human Development Index (HDI). HDI consists of three basic dimensions, knowledge as one of that three basic measured by the index of education. This index is measured by the Adult Literacy Rate and Mean Years of Schooling. Education is one of the important factors in improving human development. The enhancement of education index results in increasing the HDI of an area. Purwakarta has a vision that is made as a district that excels in education in West Java, but until now Purwakarta’s education index is still below the West Java province. One step that can be done is to seek information on the education index each district in Purwakarta, with the aim to provide the right policy in each region. Direct estimation of the components forming the HDI for districts is not feasible because these estimates will generate a great value of variance, This is due to the size of the sample used is too small. This study proposes a statistical method by performing the estimation using small area estimation. These estimates using information from surrounding areas that can improve the effectiveness of the sample size and the lower the standard error. Some surveys are conducted regularly every year, in conducting indirect estimation in the survey such as this, efficiency of estimating education index for district level can be improved by including the random effect of the area as well as the random effect of time (Sadik and Notodipuro, 2006). So in this study will be used Empirical Best Linear Unbiased Prediction (EBLUP) by combining the time series and cross-section data for estimating the education index at the level of districts in Purwakarta. The direct estimation of education index produce a larger variance than our methode, it shown by comparing mean square error (MSE) of direct method and indirect method, direct method have the largest MSE.Key words : Indirect Estimation, Small Area Estimator, EBLUP, Time Series and Cross-Section, HDI, Education Index.

Abstract

Literacy Rate (LR) is defined as percentage of population aged over 15 with ability to read and write. LR, as one of people welfare indicators, is a measurement of educational development. The indicator, as a measurement of government performance on education, can be measured if all variables related is available. Statistics Indonesia (BPS) each year calculated LR based on National Socio-Economic Survey (SUSENAS) with estimation available only on provincial level and district level. Along with establishment of autonomous regional policy, where regional government had greater power to manage its own region, availability of LR on lower levels to monitor educational development is necessary. Due to sampling design of SUSENAS, accommodated only estimation on district level, will give high variance if used to estimate on lower sub-district level, although still unbiased. Modelling LR was done with Logit-Normal approach, because LR data followed Binomial Distribution. Good estimators from inadequate sample size can be obtained with method of Small Area Estimation (SAE). Hierarchical Bayes (HB) method is one of SAE methods which are proven to give good estimate on binomial distributed data as LR. Estimation on sub-district level in District of Donggala with HB method gave better result compared to the direct estimation with lower Mean Square Error (MSE).Key words : Small Area Estimation, Literacy Rate, Hierarchical Bayes, Logit-Normal Model
