Abstract

Regresi berganda terdapat kasus khusus dalam sebuah analisa regresi, pada regresi berganda terdapat satu variabel tak bebas yang akan diprediksi, tetapi terdapat dua atau lebih variabel bebas, pemilihan model yang terbaik akan dilakukan dengan 3 metode, yaitu Metode Quadratic Mode Estimator (QME), Metode Symmetrically Trimmed Least Squares (STLS) dan Metode Left Truncated (LT).  Data yang digunakan adalah data polusi udara yang disebabkan oleh 7 variabel bebas yang meliputi jumlah kendaraan yang melewati, suhu udara, kecepatan angin, perbedaan temperatur, angin, jam aktif dan hari aktif, Pemotongan atau penyensoran dari suatu variabel respon dalam suatu model regresi adalah salah satu masalah yang sering muncul dalam banyak aplikasi.             Berdasarkan uraian dari pembahasan dan simulasi, terdapat beberapa hal penting yang dapat disimpulkan, dalam pemilihan model terbaik regresi semi-parametrik diperoleh model terbaik adalah dengan menggunakan metode QME, hal tersebut dapat dilihat dari nilai RMSE terkecil. Dalam uji parsial terdapat 2 variabel yang signifikan terhadap variabel dependent yaitu variabel yang berupa cars dan wind.speed dan juga konstanta yang berupa intercept. Dalam diagnostic checking dapat disimpulkan uji kenormalan menggunakan Kolmogorov Smirnov Test ternyata data tidak berdistribusi normal, namun karena data banyak sehingga kenormalan bisa diabaikan, sedangkan untuk uji autokorelasi menggunakan Durbin WatsonTest dapat disimpulkan tidak ada autokorelasi pada residual, untuk uji Homoskesdastisitas menggunakan Breusch Pagan Test dapat disimpulkan residual bersifat homoskedastisitas.

Abstract

This study aims to investigate the effectiveness of implementing differentiated instruction in improving student learning outcomes in Informatics for Grade X students at a vocational high school. Employing a classroom action research design over two cycles, data were collected through learning outcome tests, student attitude observations, and documentation. Both qualitative and quantitative approaches were utilized in data analysis. The findings reveal that the implementation of differentiated instruction was moderately effective, with an average N-Gain score of 75.6%. There was a significant improvement in student learning outcomes following the application of differentiated instructional methods. Quantitative analysis supported the effectiveness of this approach, as evidenced by a t-test value of 6.256 with 66 degrees of freedom and a significance level of < 0.001, thereby rejecting the null hypothesis (H₀). These results indicate that differentiated instruction can significantly enhance student engagement and academic performance, particularly in subjects such as Informatics that require logical and rapid thinking skills. The study underscores the crucial role of instructional innovation and teacher management strategies in addressing diverse student needs and optimizing learning outcomes. It recommends the broader application of differentiated instruction to enhance teaching quality and student achievement in vocational education contexts

Abstract

This study explores the implementation and actualization of human resource development (HRD) programs aimed at enhancing teacher professionalism in junior high schools within Batam’s hinterland. The research is driven by the need to address educational disparities in remote areas, particularly concerning teacher competence. Employing a qualitative approach, data were collected through interviews, observations, and document analysis involving principals, teachers, and local education officials. The findings reveal that while HRD initiatives such as training and workshops have been introduced, their implementation faces constraints, including limited funding, inadequate access to training facilities, and minimal post-training support. The actualization of these programs remains suboptimal, with few practical applications in classroom contexts. Teachers often encounter difficulties in applying theoretical knowledge due to insufficient institutional backing. This study concludes that improving teacher professionalism in hinterland areas requires increased access to practical, context-relevant training, enhanced institutional support, and greater stakeholder involvement. The results underscore the importance of aligning HRD strategies with local conditions to foster meaningful and sustainable professional growth among educators. Implications suggest the need for policy reforms and targeted investment to optimize HRD outcomes in remote educational settings
