Abstract

Mater Dei School provides education from an early age to high school, currently Mater Dei school is in great demand by students because of its superior achievements, especially in the academic field. At the junior high school level, Mater dei has a total of 496 students. This study aims to determine, namely: 1) How is the level of student satisfaction with the quality of services provided by SMP Mater Dei Pamulang, South Tangerang City, 2) What factors need to be improved by SMP Mater Dei Pamulang, South Tangerang City in order to improve service quality, 3) Knowing how the proposed improvements are prioritized for improving the quality of services at SMP Mater Dei Pamulang, South Tangerang City. The study took data of 100 respondents, then performed serqual calculations to determine the value of GAP, the results of the GAP were used as input data for Importance Performance Analysis (IPA) which then identified 6 attributes that must be considered and need to be considered by management to improve service quality. The next step is to calculate the Costomer Satisfaction Index (CSI). From the results of the analysis, the value was 79.125%. This means that the level of student satisfaction with SMP Mater Dei services is in the Satisfied category. Furthermore, the 6 attributes in question need to be recommended to managers to improve their services so that the service satisfaction value becomes 100%.

Abstract

Latar belakang penelitian adalah pendidikan anak bangsa yang cenderung menekankan masalah kecerdasan intelektual tanpa melihat faktor kebiasaan belajar, kecerdasan emosi dan peran orang tua yang sebenarnya penting menunjang keberhasilan siswa dalam meraih prestasi. Tujuan penelitian untuk mengetahui pengaruh kebiasaan belajar dan kecerdasan emosi serta perhatian orang tua secara bersama-sama terhadap penguasaan konsep matematika. Penelitian menggunakan metode survey, teknik pengambilan sampel menggunakan random sampling yang berjumlah 456 siswa dari tiga SMP Swasta di Kecamatan Pamulang Kota Tangerang Selatan. Analisis data menggunakan Regresi Berganda. Hasil penelitian menunjukkan bahwa penguasaan konsep matematika dipengaruhi secara bersama-sama oleh kebiasaan belajar, kecerdasan emosi, dan perhatian orang tua dengan persamaan regresi Ŷ = 49,376 + 0,324 X1 + 0,311 X2 + 0,448 X3. Secara parsial pula penguasaan konsep matematika dipengaruhi oleh kebiasaan belajar. Penguasaan konsep matematika dipengaruhi oleh kecerdasan emosi dan penguasaan konsep matematika dipengaruhi oleh perhatian orang tua. Implikasi dari penelitian adalah perhatian orang tua memberikan kontribusi dominan pada penguasaan konsep matematika dari pada kebiasaan belajar dan kecerdasan emosi. Maka disarankan orang tua untuk memberikan banyak perhatian kepada anaknya untuk meningkatkan hasil belajar matematika.

Abstract

The purpose of this study is to design teaching materials for Problem-based Calculus with the help of Grapmatica software in the Polar Coordinate System, Savings and Ball material, these teaching materials are implemented through valid, practical and effective learning modules. The methodology used in this study combines Plomp model research design with Gravemeijer & Cobb models. The stages of design research in this study were the preliminary research phase, the preparation of the experiment, the prototype development phase, the implementation of the experiment, the restrosfective analysis, and the assessment phase. Data analysis techniques in this research are descriptive statistics and descriptive techniques, which describe the validity, practicality and effectiveness of learning flow design through problem-based learning modules. Data collection instruments used: tests, observation sheets, interview sheets, questionnaires and field notes. The research subjects were 6th semester students of Mathematics Study Program FMIPA Univ. Pamulang who attended the Advanced Calculus lecture.The results of the validity data analysis show that the learning flow design is implemented through modules; Problem based learning that is produced has met the valid criteria. Said to be valid because it meets the characteristics of validity both in terms of content and construct. The contents of the learning design through the learning flow that are implemented in the learning module are guided by principles and are problem based. The context of the problems contained in the learning design is adapted to the context of student life and can bring students to do the mathematical process. The process of mathematics is one of the main focuses of this learning design, in order to train students to construct their own knowledge based on initial knowledge or experience. The learning flow design implemented through the learning module is practical because it is easy to use and understand, the allocation of time determined is efficient, interesting and contributes to learning in the Polar Coordinate System, Savings and Spheres. The learning flow design implemented through the learning module has also been effective because the use of this learning design has a potential impact on students' reasoning abilities on the topic of Polar, Savings and Ball Coordinate Systems. Based on these results, it can be concluded that the learning design of the topic of the Polar Coordinate System, Savings and Ball using Problem Based Calculus teaching materials with the help of grapmatica software on the material coordinate system of the lid, tubes and balls has been produced can be declared valid, practical and effective

Abstract

The spread of the Covid-19 virus globally continues to grow. The impact felt by Indonesia in addition to the many positive cases, economic, social and educational system problems. The learning process that has been carried out face-to-face has become undisturbed, so that the learning process changes its function to online learning. The purpose of this research is to obtain information on how to describe the implementation process of learning for students of the Pamulang University Mathematics Study Program during the Covid-19 pandemic as an effort for Higher Education to stop and break the chain of spreading covid-19. The research subjects were students of the Mathematics Study Program. Data processing was carried out by interviewing through cloud meetings and questionnaire response sheets using the google format. Interviews and questionnaire sheets were conducted with questions that were compiled and developed with related literature. Miles & Huberman's interactive analysis techniques were used in this study. This study obtained the results, namely, (1) students already have basic learning facilities such as leptops, computers, android-based mobile phones and internet networks; (2) The learning process has not been maximally carried out yet; (3) Lack of supervision from both lecturers and parents during the lecture or learning process; (4) The online learning process has the advantage of flexibility in time, encourages and trains students to study independently.
