Abstract

Makalah ini berupaya mengungkap bagaimana munculnya agama primitive, serta konsep monotheis dalam al-Qur’an, menurut penulis teori munculnya agama primitif dikarenkan keinginan manusia untuk menguak rahasia kehidupan. Manusia pada waktu itu menyadari bahwa kekuatan akal dan pengetahuan tidak mampu memecahkan masalah yang dihadapinya. Kesadaran akan adanya jiwa, hidup dan mati, menyadarkan kepada adanya Tuhan. Sedang menurut al-Qur’an kesadaran manusia terhadap Bergama, karena manusia memiliki kesadaran ketuhanan (fitrah).

Abstract

ABSTRACTThe measles is a major cause of child mortality among vaccine preventable disease. The incidence of measles reach out 198 cases in 2014 at Pasuruan. The incidence of measles in Pasuruan, not only in areas with low immunization coverage but also in areas with high immunization coverage, it may indicate the quality of the vaccines given bad that does not provide protection to measles disease. The aim of this study was to analyze the influence of quality of measles vaccine to the incidence of measles in Pasuruan Regency. This study was an analytic observational with case-control approach. The samples of this study taken 30 villages which had measleas cases in 2014 and 30 villages which had not measles cases in 2014. The data was analyzed by using linier regression and logistic regression. The result of the study confirmed that training (p = 0.002), knowledge (p = 0.000), and the availability of vaccine (p = 0.022) effect on the quality of measles vaccine; thus the quality of measles vaccine (p = 0.008) effect on the incidence of measles. The conclusion of this study the influence of which there are knowledge to the quality of measles vaccine; and there is influence between quality of measles vaccine to the incidence of measles. Suggestions can be drawn based on the results of this study, increase health workers knowledge about the measles immunization coverage and the quality of measles vaccine with mentoring, and require officers to use the facilities and infrastructure of immunization according to SOP (Standard Operating Procedure).Keywords: incidence of measles, quality of measles vaccine

Abstract

Superior properties of food packaging can be achieved using nanocomposite technology. However, fabrication of this materials are complex and expensive. Long term objectives of this research is the synthesis of low cost polypropylene clay nanocomposites (PPCN) via a short-cut method known as ‘cascade engineering’. Cascade engineering principle in PPCN fabrication is performed by using compatibilizer (to enable the mixing of PP and clay) masterbatch, and PPCN in one pot process using melt mixer. This paper present the experimental results using small-angle x-ray diffraction (XRD) on the thermal stability of the PPCN. Results from the XRD analysis showed that the clay was intercalated, however no significant changes were observed as a result of variation in mixing time. XRD patterns of the annealed PPCN showed reduction of MMT’s gallery (deintercalation) These phenomenon was probably caused by insufficient bonding and lack of compatibility between PP-g-MA and MMT.

Abstract

AbstrakTeknologi data mining sangat berguna untuk membantu perusahaan asuransi menemukan informasi yang sangat penting dari gudang data mereka. Data mining mengeksplorasi basis data untuk menemukan pola-pola yang tersembunyi, meramalkan tren dan sifat-sifat perilaku bisnis yang sangat berguna untuk mendukung pengambilan keputusan, mencari informasi pemrediksi yang mungkin saja terlupakan oleh para pelaku bisnis karena terletak di luar ekspektasi mereka. Analisis yang diotomatisasi yang dilakukan oleh data mining menjawab pertanyaan-pertanyaan bisnis yang dengan cara tradisional memerlukan banyak waktu untuk menjawabnya. Hasil dari sistem adalah menggali informasi dari basis data pelanggan dan transaksi yang dilakuan pelanggan meliputi pembayaran premi asuransi dan maupun proses claim yang terjadi sehingga dapat memprediksi seberapa besar kemungkinan pelanggan tersebut akan melakukan renewal atas polis asuransi mereka. Pada penelitian ini, akan dilakukan analisis klasifikasi untuk menentukan keputusan pembaharuan (renewal) polis pelanggan dengan menggunakan data polis asuransi kendaraan roda empat. Algoritma yang akan digunakan adalah C4.5 untuk kemudian dapat menjadi aturan-aturan untuk menentukan keputusan renewal polis. Dengan algoritma C4.5 yang dievaluasi menggunakan cross validation k=10, menghasilkan confussion matrix dengan tingkat akurasi sebesar 82,14%. Evaluasi menggunakan data baru yang dilakukan dengan Prototipe Sistem Informasi Prediksi yang diimplementasi dari rule C4.5 menghasilkan nilai akurasi 86% dengan error rate 14%. Kata kunci: Algoritma C4.5, Data Mining, Renewal Polis Asuransi

Abstract

The Box-Jenkins forecasting method is one of the time series forecasting methods. This method uses past values as dependent variables and independent variables are ignored. Box-Jenkins (ARIMA) method has advantages that can be used on non-stationary data, can be used on all data patterns including seasonal data patterns so this method can be used to predict cases of DHF in East Java Province. This research was conducted to determine the best model with seasonal ARIMA forecasting model and also to analyze the result of DHF case forecasting in East Java Province. The analysis result shows that the best model for DHF case in East Java Province is ARIMA (1,1,2)(2,1,1)12. The best model has fulfilled the test requirement that is parameter significance test and diagnostics check. Forecasting results show the number of DHF cases in 2017-2018 will experience an upward trend. The total number of DHF cases in 2017 was 14,277 cases and increased to 22,284.54 DHF cases in 2018. The forecasting results showed that the highest peak of DHF cases occurred in January 2017 with 1,914.22 cases and then decrease in the next month until the lowest case occurred in October with 768.46. The forecast for 2018 also shows that the highest DHF cases occurred in January with 3455.55 and declined to the lowest in October with 1126.49 cases. MAPE value in the forecast is 43.51%. The MAPE value indicates that the forecasting is good enough, adequate and feasible to use.

Abstract

Classification and Regression Tree (CART) was a method of Machine Learning where data exploration was done by decision tree technique. CART was a classification technique with binary recursive reconciliation algorithms where the sorting was performed on a group of data collected in a space called a node / node into two child nodes (Lewis, 2000). The aim of this study was to predict family participation in Elderly Family Development program based on family behavior in providing physical, mental, social care for the elderly. Family involvement accuracy using Bagging CART method was calculated based on 1-APER value, sensitivity, specificity, and G-Means. Based on CART method, classification accuracy was obtained 97,41% with Apparent Error Rate value 2,59%. The most important determinant of family behavior as a sorter was society participation (100,00000), medical examination (98,95988), providing nutritious food (68.60476), establishing communication (67,19877) and worship (57,36587). To improved the stability and accuracy of CART prediction, used CART Bootstrap Aggregating (Bagging) with 100% accuracy result. Bagging CART classifies a total of 590 families (84.77%) were appropriately classified into implement elderly Family Development program class.
