PERBANDINGAN ANTARA METODE CART (CLASSIFICATION AND EGRESSION TREE) DAN REGRESI LOGISTIK (LOGISTIC REGRESSION) DALAM MENGKLASIFIKASIKAN PASIEN PENDERITA DBD (DEMAM BERDARAH DENGUE) R Lestawati; Rais Rais; I T Utami

Classification is one of statistical methods in grouping the data compiled systematically. The classification of an object can be done by two approaches, namely classification methods parametric and non-parametric methods. Non-parametric methods is used in this study is the method of CART to be compared to the classification result of the logistic regression as one of a parametric method. From accuracy classification table of CART method to classify the status of DHF patient into category of severe and non-severe exactly 76.3%, whereas the percentage of truth logistic regression was 76.7%, CART method to classify the status of DHF patient into categories of severe and non-severe exactly 76.3%, CART method yielded 4 significant variables that hepatomegaly, epitaksis, melena and diarrhea as well as the classification is divided into several segmens into a more accurate whereas the logistic regression produces only 1 significant variables that hepatomegaly

Palu city is one of the cities with unstable changes of natural conditions. The natural conditions such as the frequency of rainy day, temperature and humidity which are always changeable bring bad impacts and will cause of diseases especially dengue hemorrhagic fever (DBD). Therefore, it needs an action to recognise whether or not the natural condition factor influences the spread of DBD and determines what factors of the natural condition can influence the spread of DBD. This research applied quantile regression in the case of DBD in Palu city. Quantile regression is an analysis technique regarding to the functional relationship between one dependent variable with one or more independent variables which can provide accurate and stable results even though there will be outliers. Based on the result of the research, it is obtained that the natural condition factor affected the spread of DBD. This is because from 3 natural conditions only 11 significant or influential quantiles on the tested data, the quantiles are 0,30; 0,35; 0,40; 0,45; 0,50; 0,55; 0,60; 0,65; 0,70; 0,75 and 0,80. Meanwhile the most influential factor of natural conditions in spreading DBD is the frequency of rainy day because it has positive which means that 1 progress of percentage will increase the quantity of DBD case.

The simulation of handling of outliers on regression analysis used the method which was commonly used to predict the parameter in regression analysis, namely Least Median Square (LMS) due to the simple calculation it had. The data with outliers would result in unbiased parameter estimate. Hence, it was necessary to draw up the robust regression to overcome the outliers. The data used were simulation data of the number of data pairs ( X,Y) by 25 and 100 respectively. The result of the simulation was divided into 5 subsets of data cluster of parameter regression prediction by Ordinary Least Square (OLS) and Least Median Square (LMS) methods. The prediction result of the parameter of each method on each subset of data cluster was tested with both method to discover the which better one. Based on the research findings, it was found that The Least Median Square (LMS) method was known better than Ordinary Least Square (OLS) method in predicting the regression parameter on the data which had up to 3% of the percentage of the outlier.

Criminality is all kinds of actions and deeds which is economically and psychologically harmful. The statistical method could be used to classify the crime is cluster analysis. Cluster analysis is a multivariate method which aims to classify a sample of subjects (or objects) on the basis of a set of measured variables into a number of different groups such that similar subjects are placed in to the same group. The objective of this research is to classify Regency/City in Central Sulawesi Province based on the criminality indicator and to discover the profile of each cluster which had been formed. The results of the study shows that those are two clusters formed: Cluster 1 consists of Buol, Banggai, Morowali, Toli-Toli, Donggala, and Tojo Una-Una Regency; Cluster 2 consists of Regency/Palu City, and Parigi Moutong. The profile of each cluster is: Cluster 1 with low crime rate on average and Cluster 2 with high crime rate on average.Keywords : Cluster Analysis, Complete Linkage, Criminality, Hierarchy Method.

Teknologi berkembang dengan pesat pada era sekarang, seiring perkembangan teknologi tersebut maka ada dampak yang ditimbulkan. Seperti pakan Burung Lovebird pun menjadi perhatian bagi sebagian orang untuk memadukannya dengan teknologi, kami pun mulai mencari ide untuk membuat alat pakan burung Lovebird otomatis dan juga dapat memonitoring kondisi kesediaan pakannya, alat pakan burung Lovebird otomatis ini sangat membantu bagi para peternak lovebird. Dengan alat ini peternak burung Lovebird tidak khawatir akan kelaparan dan juga akan kesediaan pakannya. Dengan sistem penjadwalan sehari 2 kali maka kebutuhan makan lovebird sehari-hari dapat terpenuhi. Dari pemaparan permasalahan di atas, maka sangat tepat jika dibuatkan sebuah judul “Pakan Burung Otomatis Menggunakan Arduino Berbasis Internet of Things”. Sistem ini dirancang dan dibangun dengan menggunakan teknologi Microcontroller Arduino sebagai otomatisasinya, serta menggunakan NodeMCU ESP8266 yang berperan sebagai web client, yang dapat menerima dan mengirim data ke website berbasis PHP & MySQL Kata kunci : Weighted Moving Averages, peramalan, pmi, golongan darah

One of Indonesia's development goals in 2020-2024 is to form quality and competitive human resources. One of the efforts to achieve this goal is to improve the quality of maternal and child health. However, the issue of Maternal and Child Health (MCH) is still a challenge for the Indonesian health system. This study aims to determine the modeling and to obtain provincial groupings based on the degree of maternal and child health in Indonesia. The method used is Structural Equation Modeling Partial Least Square-Prediction Oriented Segmentation (SEM PLS-POS). The results of the PLS SEM analysis showed that the environmental variables and health services had a significant effect on the health status of mothers and children with an R2 value of 48.8%. The grouping of provinces based on the degree of maternal and child health in Indonesia using PLS-POS produces 3 segment classes. Segment 1 consists of 11 provinces, segment 2 consists of 13 provinces and segment 3 consists of 10 provinces with a large influence between different latent variables.

Kegiatan akademik di SMA Negeri 3 Tegal belum memberikan transparansi nilai pada siswa maupun orang tua. Masih dijumpai penyampain laporan nilai yang manual sehingga dirasa kurang efektif karena terjadipenundaan waktu konfirmasi kepada orangtua. Dengan dibuatnya sistem informasi pelaporan nilai berbasis SMS gateway pada SMA N 3 Tegal, agar dalam penyampain informasinya lebih efisien. Sistem informasi pelaporan nilai ini nantinya digunakan untuk memberikan informasi mengenai nilai siswa, baik nilai ulangan harian, UTS, dan UAS siswa. Pada pengumpulan data yang didapat dengan menggunakan cara literatur, penyusunan, pengujian, observasi dan wawancara. Untuk itu, maka dibutuhkan suatu solusi permasalahan penyampain yang manual diganti dengan cara yang baru yaitu sebuah sistem informasi pelaporan nilai berbasis SMS Gateway.
