Di awal tahun 2020, dunia dikagetkan dengan kejadian infeksi berat dengan penyebab yang belum diketahui, yang berawal dari laporan dari Cina kepada World Health Organization (WHO) terdapatnya 44 pasien pneumonia yang berat di suatu wilayah yaitu Kota Wuhan, Provinsi Hubei, China, tepatnya di akhir tahun 2019. Pada perkembangannya, wabah ini kemudian diidentifikasi sebagai wabah Virus Covid-19. Penambahan jumlah kasus COVID-19 berlangsung sangat cepat, sampai dengan 16 Februari 2020, secara global dilaporkan 51.857 kasus terkonfirmasi di 25 negara dengan 1.669 kematian (CFR 3,2%). Di Indonesia ada lebih dari 2 ribu kasus ditemukan dan hampir 200 orang telah meninggal. Di wilayah Jawa barat, kasus positif Covid-19 juga terus bertambah. Data penyebaran virus Corona Covid-19 di Jawa Barat mengalami perubahan, Rabu (1/4/2020). Terpantau melalui situs resmi Pusat Informasi dan Koordinasi Covid-19 Provinsi Jawa Barat (Pikobar), jumlah orang terpapar positif Corona mencapai 198 orang. Data yang diakses dari pikobar.jabarprov.go.id tersebut juga merilis sudah ada 11 pasien yang dinyatakan sembuh dan diperbolehkan pulang dari rumah sakit. Sementara jumlah pasien yang meninggal dunia berjumlah 21 orang. Sedangkan untuk pasien dalam pengawasan (PDP), jumlah yang telah diproses dalam pengawasan mencapai 727 orang. Sedangkan yang telah selesai menjalani pengawasan mencapai 242 orang. Total PDP di Jabar berjumlah 969 orang. Berbekal dari data Pusat Informasi dan Koordinasi Covid-19 Jawa Barat, penulis tertarik melakukan penelitian untuk memprediksi penyebaran kasus positif Covid-19 di Jawa Barat. Dalam penelitian ini, model yang digunakan adalah Hybrid. Data set yang digunakan adalah data pasien positif Covid-19 mulai bulan April 2020 sampai dengan bulan Februari 2021. Berdasarkan hasil penelitian yang sudah dilakukan, model Hybrid mampu memprediksi jumlah penyebaran kasus Covid-19 di Jawa Barat. Hal ini dibuktikan dengan hasil training teknik Hybrid memiliki error rate sebesar 0,4615, yang dilanjutkan dengan analisa akurasi prediksi selama tiga bulan, yaitu bulan Desember 2020, Januari, dan Febrauri 2021. Dari hasil prediksi, model Hybrid memiliki nilai rata – rata Mean Absolute Deviation (MAD) sebesar 351. Sedangkan berdasarkan analisa prediksi dengan teknik Mean Absolute Percentage Error (MAPE) memiliki rata rata tingkat kesalahan sebesar 0,2061 atau 20,6%.

Abstract - The process of admitting new students is an annual routine activity that occurs in a university. This activity is the starting point of the process of searching for prospective new students who meet the criteria expected by the college. One of the colleges that holds new student admissions every year is Buana Perjuangan University, Karawang. There have been several studies that have been conducted on predictions of new students by other researchers, but the results have not been very satisfying, especially problems with the level of accuracy and error. Research on ANFIS studies to predict new students as a solution to the problem of accuracy. This study uses two ANFIS models, namely Backpropagation and Hybrid techniques. The application of the Adaptive Neuro-Fuzzy Inference System (ANFIS) model in the predictions of new students at Buana Perjuangan University, Karawang was successful. Based on the results of training, the Backpropagation technique has an error rate of 0.0394 and the Hybrid technique has an error rate of 0.0662. Based on the predictive accuracy value that has been done, the Backpropagation technique has an accuracy of 4.8 for the value of Mean Absolute Deviation (MAD) and 0.156364623 for the value of Mean Absolute Percentage Error (MAPE). Meanwhile, based on the Mean Absolute Deviation (MAD) value, the Backpropagation technique has a value of 0.5 and 0.09516671 for the Mean Absolute Percentage Error (MAPE) value. So it can be concluded that the Hybrid technique has a better level of accuracy than the Backpropation technique in predicting the number of new students at the University of Buana Perjuangan Karawang.   Keywords: ANFIS, Backpropagation, Hybrid, Prediction

Aim: To help parents assess disability in their own children using World Health Organization (WHO) International Classification of Functioning, Disability and Health, Child and Youth Version (ICF-CY) code qualifier scoring and to assess the validity and reliability of the data sets obtained. Method: Parents of 162 children with spina bifida, spinal muscular atrophy, muscular disorders, cerebral palsy, visual impairment, hearing impairment, mental disability, or disability following brain tumours performed scoring for 26 body functions qualifiers (b codes) and activities and participation qualifiers (d codes). Scoring was repeated after 6 months. Psychometric and Rasch data analysis was undertaken. Results: The initial and repeated data had Cronbach α of 0.96 and 0.97, respectively. Inter-code correlation was 0.54 (range: 0.23-0.91) and 0.76 (range: 0.20-0.92). The corrected code-total correlations were 0.72 (range: 0.49-0.83) and 0.75 (range: 0.50-0.87). When repeated, the ICF-CY code qualifier scoring showed a correlation R of 0.90. Rasch analysis of the selected ICF-CY code data demonstrated a mean measure of 0.00 and 0.00, respectively. Code qualifier infit mean square (MNSQ) had a mean of 1.01 and 1.00. The mean corresponding outfit MNSQ was 1.05 and 1.01. The ICF-CY code τ thresholds and category measures were continuous when assessed and reassessed by parents. Participating children had a mean of 56 codes scores (range: 26-130) before and a mean of 55.9 scores (range: 25-125) after repeat. Corresponding measures were −1.10 (range: −5.31 to 5.25) and −1.11 (range: −5.42 to 5.36), respectively. Based on measures obtained at the 2 occasions, the correlation coefficient R was 0.84. The child code map showed coherence of ICF-CY codes at each level. There was continuity in covering the range across disabilities. And, first and foremost, the distribution of codes reflexed a true continuity in disability with codes for motor functions activated first, then codes for cognitive functions, and, finally, codes for more complex functions. Conclusions: Parents can assess their own children in a valid and reliable way, and if the WHO ICF-CY second-level code data set is functioning in a clinically sound way, it can be employed as a tool for identifying the severity of disabilities and for monitoring changes in those disabilities over time. The ICF-CY codes selected in this study might be one cornerstone in forming a national or even international generic set of ICF-CY codes for the benefit of children with disabilities, their parents, and caregivers and for the whole community supporting with children with disabilities on a daily and perpetual basis.

Demand forecasts are extremely important for manufacturing industry and also needed for all type of business and business suppliers for distribution of finish products to the consumer on time. This study is concerned with the determination of accurate models for forecasting cement demand. In this connection this paper presents results obtained by using a self-organizing model and compares them with those obtained by usual statistical techniques. For this purpose, Monthly sales data of a typical cement ranging from January, 2007 to February, 2016 were collected. A nonlinear modelling technique based on Group Method of Data Handling (GMDH) is considered here to derive forecasts. Forecast were also made by using various time series smoothing techniques such as exponential smoothing, double exponential smoothing, moving average, weightage moving average and regression method. The actual data were compared to the forecast generated by the time series model and GMDH model. The mean absolute deviation (MAD, mean absolute percentage error (MAPE) and mean square error (MSE) were also calculated for comparing the forecasting accuracy. The comparison of modelling results shows that the GMDH model perform better than other statistical models based on terms of mean absolute deviation (MAD), mean absolute percentage error (MAPE) and mean square error (MSE).
