Abstract

The purpose of this study is to formulate strategies and to develop appropriate scenario for the management of an industrial area towards Eco Industrial Park. Analytical Hierarchy Process (AHP) is used as the analytical method. Industrial actors in an industrial area can jointly improve environmental, economic, and social performance, through the minimization of environmental impact and also has the ability to make products with competitive advantage in the market, based on the results of gap analysis between existing conditions and the ideal concept and Eco Industrial Park benchmarking. The analysis and interviews with several experts showed that, in the industrial estate management of the Eco Industrial Park, the most important objective that needs be achieved is environmental and ecological sustainability.

Abstract

The study aimed to assess the role of palm oil and rubber toward the economy in West Kalimantan. Another aim was to develop oil palm and rubber industry to strengthen the economy of West Kalimantan. The method used in this research was the analysis of Input-Output. The main data was the Input-Output (IO) data in 2011 from the Central Bureau of Statistics (BPS), which consists of 54 sectors. The results show that the industrial output of palm oil and rubber, as well as oil palm and rubber, is still low. Weak innovation and technology lead to the low output and role of these two sectors to the economy of West Kalimantan. Another obstacle that leads to the economy of rubber and palm oil industries under the standard is the lack of motivation research, infrastructure, and connectivity.

Abstract

In this paper, we discuss the generalized linear models with ordinal response for correlated data in nested area. Some basic concepts are described, that is nested spatial, threshold model, and cumulative link function. Due to correlated data used for this modeling, Generalized Estimating Eequation (GEE) is used as model parameters estimation method. Nested is shown by the model building and its application on nested spatially data. In this method, some Working Correlation Matrices (WCM) are able to be specified depend on the nature and type of the data. In this study, 3 types of WCM and 2 types of parameters estimation covariance are used to see the results of parameters estimation from these combinations. As a conclusion, independent WCM is appropriate to the data.

Abstract

Over the past year, a significant amount of research has explored the logistic regression models foranalyzing correlated categorical data. In these models, it is assumed that the data occur in clusters,where individuals within each cluster are correlated, but individuals from different clusters areassumed independent. A commonly used in modeling correlated categorical univariate data is toassume that individual counts are generated from a Binomial distribution, with probabilities varybetween individuals according to a Beta distribution. The marginal distribution of the counts is thenBeta-Binomial. In this paper, a generalization of the model is made allowing the number ofrespondent m, to be random. Thus both the number units m, and the underlying probability vectorare allowed to vary. We proposed the model for correlated categorical data, which is generalized toaccount for extra variation by allowing the vectors of proportions to vary according to a Dirichletdistribution. The model is a mixture distribution of multinomial and Dirichlet distribution, and wecall the model as the beta-binomial multivariate model.

Abstract

Dalam penelitian ini daya tahan mahasiswa didefinisikan sebagai kemampuannya untuk terusberstatus mahasiswa aktif atau tidak putus kuliah. Tingkat putus kuliah pada perguruan tinggijarak jauh (PTJJ) seperti UT merupakan salah satu contoh data yang mengandung data tersensor.Penelitian mengenai daya tahan belajar mahasiswa PTJJ telah banyak dilakukan, namun data putuskuliah tidak dipandang sebagai data tersensor. Dalam penelitian ini data putus kuliah dipandangsebagai data tersensor jenis 1 (sensor waktu sebelah kanan). Regresi Cox dipergunakan untukmengidentifikasi faktor-faktor yang mempengaruhi mahasiswa putus kuliah di UT.Dari pemodelan inisecara umum ditemukan bahwa mahasiswa UT banyak mengalami putus kuliah.Peubah penjelasyang berpengaruh nyata terhadap daya tahan belajar mahasiswa UT adalah: jenis kelamin, usia,indeks prestasi (IP), indeks prestasi kumulatif (IPK), status cuti akademik, jurusan asal (latarbelakang pendidikan formal), dan status pekerjaan mahasiswa.

Abstract

Rice is one of the main foods in Indonesia. A change of rice price will cause a major effect in the lives of consumers. Onthe other hand, there are so many factors that influence the rice price. Thus finding key factors which are significant to therice price, as well as forecasting the consumer’s rice price are needed in order to maintain the stabilization of rice price.The second objective is to find key factors which influence the rice price by using multiple linear regression models. Theparameters were estimated by ordinary least square methods. There are 6 variables that are significant at α=5%, which arethe consumer’s rice price at the previous period, rice production at the current and previous period, farmer’s GKP price,realization of domestic stock, and total rice import. The rice price will increase if the GKP price and realization of domesticstock increase whereas total rice import and the consumer’s rice price at the previous period have negative influencestowards the rice price. In this model rice production at the current and previous period have positive signs, contradictory tothe microeconomic theory where when the rice production increases, there will be an excess supply and the price will drop.That condition will occur only if the commodity is a free commodity and the rice is at the sufficiency level but inIndonesia, rice is affected by the government’s policy and the rice productivity is left behind by the demand. Forecastingthe consumer’s rice price for the next five years was the last objective of this research. ARIMA Box–Jenkins Method, X-12ARIMA, Winter’s Method, and Trend Analysis were compared to find the best statistical model to forecast the consumer’srice price. X-12 ARIMA turns out to be the best method because it has the smallest MAPE, MAD, and MSD value. Thisresult is a satisfactory because according to Findley et al. (1998) X-12 ARIMA has the capability to adjust seasonal andtrading day factors which usually causes fluctuations in an economic time series data. Besides that, the X-12 ARIMAmethod also enhances the lack of other forecasting techniques used in this research to add regression effects. TheregARIMA makes it possible to add the user defined parameters, in this case the length of month parameter. The length ofmonth parameter rescales the monthly observation by a weight corresponding to the month relative length with respect tothe average length. The seasonal adjusted data from the original time series data is aimed to simplify the data withoutloosing important information.

Abstract

Gejala-gejala aneh dan tidak diharapkan sering terjadi pada dunia nyata. Hal ini juga terjadi pada kemometrik khususnyapada data kalibrasi. Ketidak sesuaian model yang akan mencerminkan respon aslinya dapat disebabkan oleh adanya outlier, bentuk data yang sangat tidak linier, multikolinier, dan lain-lain. Dalam tulisan ini akan ditunjukkan teknik untukmengatasi permasalahan-permasalahan tadi dengan melakukan reduksi peubah, pendeteksian outlier dan transformasispektroskopi. Dapat ditunjukkan bahwa dengan melakukan pengendalian terhadap permasalahan-permasalahan di atasdapat mereduksi KTG (Kuadrat Tengah Galat) dan meningkatkan ketepatan model sampai 30 %.

Abstract

To control quality of rainfed areas as well as improvement of farmers’ welfare is efforts already has been done by local government (Ponogoro) however it’sstill not success yet because it used to partial approach. Therefore, it is very important to research and develop model how to control quality of rainfed based on community empowerment with integrated (system) ap­proach.The location of research is in Ponorogo Districtwith 326 respondens, consist of 6experts, 20 linkage agencies staff and 300 farmers. Beside useAnalytical Hierarchy Process (AHP), Interpretative Structural Modelling (ISM), and System, this re­search also use univariat and bevariate analyze (Chi- Square and Structure Equation Model- SEM).Based on data and informa­tion that collected and analyzed, this research develop model that reflected the the real situation (fact), that can be simulated and validated. The model is established with system approach of population, local government services and ecology. The model vali­dated by absolute mean error (AME) and absolute variation error (AVE) that reflected variance between actual and value from model less than 10%, it show the model is a valid.This mean model able to simulate any changing of rainfed areas quality con­trol both in short or long term period.Other significant factors that related with rainfed areas quality control is farmers know­ledge (p-value= 0,030) and farmers behavior (p-value=0,040).The empowerment of farmers indicated by food and nutrition security (γ = 1), settlement and sanitation security (γ = 0.23), healthy security (γ = 0.01)and education security (γ = 0.24). The empowerment of farmers influenced by coping strategy (β=0.41), that reflected by how farmer survive in production, consump­tion and marketing of agriculture with respective of γ is0.59, 0.27, 037 and 0.42. In line with these statistic analysis AHP, ISM results and validation model, this research formulated empowerment policy focus on life skill development through farmer group. In the beginning process of life skill development focus on soft skill and then hard skill later on up to achieve sustainable self help group in managing their rainfed areas.Keywords: rainfed, quality, control, empowerment, model, system, coping strategy
