Abstract

Self regulated learning is a learning system applied in universities. Therefore, self regulated learning is needed by students in taking courses in college. Based on the results of previous studies found that students self regulated learning is still low. This study aims to improve students self regulated learning by using computational mathematics teaching materials in numerical method courses. The method used in this study is quasi-experimental with non-equivalent control group design. Result of this study shows that increasing students self regulated learning that using computational mathematics teaching materials is not better than students that not using the teaching materials.

Abstract

The implementation of these programs exist for handling social problems i.e. drug abuse conducted by the National Narcotics Agency through the efforts of prevention and eradication of Drug abuse and Dark Outlets (P4GN). This effort is conducted through a program of alternative Urban Community Empowerment which renders region Kampung farm, East Jakarta as targets or targets in its implementation. The purpose of this study was to describe the implementation of Alternative urban communities Empowerment Programme In the region Vulnerable to drugs in Agriculture in East Jakarta as well as to know the factor endowments and restricting factors of alternative urban communities Empowerment Programme In the region Vulnerable to drugs in Agriculture in East Jakarta. This type of research is a research dekriptif by using the pendekata method of the qualitative. The results showed that in practice there were indicators such as on the appropriateness of the policy in which to solve the problem have not yet seen a good run because the empowerment program takes a long time, precision implementation seen from the main actors and how the role of private parties and communities that want to get involved has gone well, the precision ofthe target associated with the intervention, objectives and community responses that have not been run well related to the environment, the precision of the internal and external environment the external environment which still lack in the mass mediato deliver news about the empowerment program alternatives, and the precision ofthe process related to the readiness of the implementing agencies and the communities where it is still not fully prepared to get involved. In the study also found an inhibitor factor is communication, resources, and disposition. Recommendations that can be given is associated with intensity about the socialization program, human resources and financial resources is related to the addition of officers in the field required and budget down in accordance with the schedule, and the disposition related to the willingness and commitment of the employees of improved returns.

Abstract

Performa mahasiswa memiliki peran penting dalam menghasilkan lulusan yang berkualitas. Kurang optimalnya performa mahasiswa terlihat dari hasil belajar mahasiswa pada mata kuliah Persamaan Diferensial rata-rata sekitar 70 dan masih ada yang mendapatkan nilai kurang dari 70 sekitar 38%, serta kurangnya kemandirian belajar mahasiswa. Oleh karenanya optimalisasi performa mahasiswa perlu dilakukan. Tujuan dari penelitian ini adalah untuk mendapatkan optimalisasi performa mahasiswa melalui penggunaan bahan ajar komputasi matematika berbantuan software Mathematica. Kemandirian belajar dan hasil belajar mahasiswa dijadikan sebagai sasaran performa mahasiswa yang akan dioptimalkan. Penelitian ini dilaksanakan di Program Studi Pendidikan Matematika FKIP Universitas Muhammadiyah Tangerang yang berjumlah 24 mahasiswa pada mata kuliah Persamaan Diferensial menggunakan bahan ajar Komputasi Matematika Berbantuan Software Mathematica. Penelitian ini merupakan penelitian kuasi eksperimen dengan desain eksperimen yang digunakan adalah one-group pretest-posttest design. Hasil yang didapat dari penelitian ini adalah terdapat perbedaan yang signifikan antara sebelum dan sesudah penggunaan bahan ajar untuk kemandirian belajar dan hasil belajar mahasiswa melalui uji t. Rata-rata peningkatan persentase kemandirian belajar dan hasil belajar mahasiswa secara berturut-turut sebesar 7% dan 24%.Students’ performance has an important role in producing quality graduates. Less optimal students’ performance can be seen from student learning outcomes in Differential Equation courses an average of around 70 and there are still those who score less than 70 about 38%, and lack of students’ self regulated learning. Therefore, optimizing students’ performance needs to be done. The purpose of this study is to obtain the optimization of students’ performance using computational mathematics teaching materials assisted by Mathematica software. Self regulated learning and student learning outcomes are targeted as students’ performance to be optimized. This research was conducted in the Mathematics Education Study Program FKIP Muhammadiyah University of Tangerang, totaling 24 students in the Differential Equation course using Mathematica Software Computational Mathematics teaching material. This research is a quasi-experimental research with the experimental design used is a one-group pretest-posttest design. The results obtained from this study are that there are significant differences between before and after the use of teaching materials for self-regulated learning and student learning outcomes through t-test. The average increase in the percentage of self-regulated learning and student learning outcomes are 7% and 24%, respectively.

Abstract

Penelitian ini bertujuan untuk mengisolasi senyawa triterpenoid dari rimpang Alpinia purpurata dan fabrikasi nanopartikel ekstrak n-heksana serta membandingkan aktivitas sitotoksik antara nanopartikel dan ekstrak n-heksana. Senyawa triterpenoid diisolasi dari ekstrak n-heksana menggunakan kromatografi kolom gravitasi dan KLT Preparatif. Metode yang digunakan untuk fabrikasi ekstrak n-heksana menjadi nanopartikel adalah sonikasi dengan menggunakan prosesor ultrasonik. Penentuan aktivitas sitotoksik ekstrak n-heksana menggunakan metode BSLT (Brine Shrimp Lethality Test). Hasil analisis GC-MS isolat triterpenoid memiliki berat molekul sebesar 426 g/mol diduga merupakan senyawa Lupeol. Berdasarkan analisis ukuran partikel menggunakan instrumen PSA, nanopartikel ekstrak n-heksana memiliki ukuran 278,0 nm. Hasil uji sitotoksisitas ekstrak n-heksana dan nanopartikel ekstrak n-heksana menghasilkan LC50 berturut-turut sebesar 109,668 ppm dan 86,783 ppm. Ekstrak n-heksana dalam bentuk nanopartikel dapat meningkatkan bioaktivitas.
