AbstrakPenelitian ini bertujuan untuk menganalisis model simultan model logistik satu parameter (ML1P) dengan waktu respon. Analisis terhadap model menggunakan data simulasi, yang skenario pembangkitan data simulasi dilakukan berdasarkan banyaknya peserta tes (500, 1000) dan banyaknya soal tes (11, 20, 40 ANALYSIS OF SIMULTANEOUS MODEL OF ONE PARAMETER LOGISTIC MODEL AND RESPONSE TIME BASED ON SIMULATION DATA AbstractThe aim of this research is to analyse simultaneous model One Parameter Logistic Model (1-PLM) and respon time. The analysis of model used the simulation data, where the data generation scenario was done based on the number of test takers (500, 1000) and the number of test items (11, 20, 40). Parameter estimation method used the Bayesian method, Markov Chain Monte Carlo. The analysis of model was done with the accounting of the distance of true value and estimated parameter. The Analysis methods use Root Mean Square Error (RMSE), Standart Error (SE) and bias.The result of research reveals the performance of parameter estimation result for the test item (the test item difficulty, test item slowness, and the effort to complete the item test) is not influenced by the number of the test items. However, the performance of parameter estimation result for the test takers (the speed and ability of the test takers) is influenced by the number of the test items. The more test items there are, the closer is the parameter estimation result to the true parameter.

The background of the non-formal education is the improvement of informal education, the complement of formal education. Sanggar itself is a place of art activities, as an effort to improve the skills of the students built studio. To do that research on non-formal education as an effort to improve the skills of street children who become guided in the studio. The type of research used in this study is field research, using a qualitative approach. Data analysis used in this research is descriptive done by data reduction and data exposure. The result of this research is that the Bodol studio provides skills that match the interests and talents possessed by the sanggar children. The skills possessed by the assisted children of the studio are the skills of playing music. Efforts made by the studio to improve skills: provide assistance, have books that can support, the availability of supporting tools and the support of interests and talents owned by the child who became the guard studio.Keywords: Non Formal Education, Skills and Street Children

<p>Penilaian merupakan akhir dari proses pembelajaran yang dapat dilakukan melalui ujian. Soal yang digunakan harus mampu mengukur kemampuan peserta didik. <em>Classical Test Theory</em> (CTT) dan <em>Rasch model</em> merupakan analisis statistika untuk menganalis butir soal. Desain dalam penelitian ini adalah penelitian deskriptif. Hasil analisis terhadap 50 soal menggunakan metode CTT, didapatkan hasil bahwa hanya 21 soal yang memenuhi kriteria <em>item difficulty</em> dan <em>item discriminant</em>. Analisis <em>Rasch model</em>, memberikan informasi bahwa secara keseluruhan kualitas soal dikatakan baik berdasarkan pola kurva <em>item information function</em>. Analisis ini juga memberikan informasi terdapat 42 soal yang layak karena memenuhi kriteria <em>item fit,</em> dan 8 soal yang harus dievaluasi lagi. Analisis menggunakan <em>Rasch model</em> lebih baik dibandingan dengan CTT, sehingga 8 soal yang tidak layak berdasarkan analisis tersebut harus dievaluasi dengan mengubah bentuk studi kasus pada soal tersebut dan membuat inovasi metode pembelajaran terkait materi pada 8 soal tersebut.</p><p><strong>Kata kunci</strong>: analisis soal, <em>Classical Test Theory</em>, <em>Rasch model</em>.</p>
