Abstract

Tujuan dari penelitian ini adalah untuk mengembangkan produk berupa pocket bookberbasis scaffolding. Materi ajar yang diberikan peneliti adalah Limit Fungsi untuk siswa Kelas XI MA/SMA. Subjek dalam penelitian ini adalah siswa kelas XI MIA 2 SMAS Imelda Medan. Dalam penelitian ini, proses pengembangan pocket bookberbasis scaffolding mengacu pada model pengembangan 4D yang telah diubah menjadi 3D yaitu define (pendefinisian), design (perancangan) dan development (pengembangan). Validasi produk Pocket bookberbasis scaffolding mendapatkan nilai rata-rata validasi secara keseluruhan yaitu 4,22 yang masuk kategori baik. Untuk tingkat keefektifan pocket book terhadap kemampuan pemahaman matematis masuk ke dalam kategori sangat baik dengan persentase ketuntasan siswa pada saat pretes 6,67% menjadi 87% saat post test yang diyakinkan dengan dilakukannya uji t mendapatkan hasil t hitung yaitu 6,697 dan t tabel yaitu 2,145, dengan ketentuan t hitung > t tabel, yang artinya hasil uji t tersebut mengalami perbedaan yang signifikan. Kata Kunci: Pocket Book, Scaffolding, Kemampuan Pemahaman Matematis ABSTRACT The purpose of this research is to develop a product in the form of a scaffolding-based pocket book. The teaching material given by the researcher is Limit Function for Class XI MA/SMA students. The subjects in this study were students of class XI MIA 2 SMAS Imelda Medan. In this study, the process of developing a pocket bookbased on scaffolding refers to a 4D development model that has been converted into 3D, namely define, design and development. The validation of the scaffolding-based Pocket bookproduct got an overall average value of 4.22 which was in the good category. For the level of effectiveness of the pocket bookon mathematical understanding abilities, it is in the very good category with the percentage of students' completeness at the pretest 6.67% to 87% at the post-test which is convinced by the t-test to get the t-count results that is 6.697 and the t-table is 2.145, with the provisions of t arithmetic > t table, which means that the results of the t test have a significant difference.

Abstract

This study aims to analyze and measure environmental performance efficiency in residential areas in Medan City using the Data Envelopment Analysis (DEA) method combined with a fuzzy approach. Environmental performance is measured based on relevant inputs and outputs, where the data used are secondary data obtained from previous research reports. Fuzzification is applied to address uncertainty in the data by converting input and output values into Triangular Fuzzy Numbers (TFN). The results of the study show that out of the 4 Decision Making Units (DMUs) studied without using the fuzzy approach, only the Helvetia housing complex achieved 100% efficiency. Meanwhile, the efficiency values for Tuntungan, Martubung, and Johor housing estates were 85.92%, 88.69%, and 94.87%, respectively. When the fuzzy approach was applied, the efficiency values of the Johor and Helvetia housing estates reached 100% efficiency, while the Tuntungan and Martubung housing estates had an efficiency of 78.22%, indicating inefficiency. This inefficiency is caused by excessive use of drainage inputs, indicating that these housing complexes are unable to produce environmental outputs commensurate with the inputs used. This study recommends improving the quality and quantity of environmental management and cleanliness, as well as the availability and quality of green spaces, to enhance environmental efficiency in housing. The findings of this study provide important insights into the efficiency of environmental performance measurement and highlight opportunities for improvement in environmental management within housing.
