Abstract

One of the efforts made so that humans are able and able to develop their potential is through a learning process. Blended learning encourages students to be more active and increases independence in learning. Students are required to learn and access material independently, and complete assignments given by the teacher, both individually and in groups. This literature review aims to discuss strategies for implementing blended learning as a student learning method. With the development of science and technology which is increasingly rapid, nowadays it has a lot to affect human life so that it can have a positive impact, namely improving the quality of life and making human work easier. The negative impact is that it can cause changes in the values, norms, rules, or morals of life adopted by the community. Therefore we need people who are able to think critically, creatively, logically and take the initiative in responding to issues in society that are caused by the impact of the development of science and technology, especially in the world of education.

Abstract

Radius bahan bakar kompak dan kernel selama ini dibuat tetap pada nilai baku yang diadopsi oleh proyek reaktor suhu tinggi. Radius kompak bahan bakar ditetapkan 0,6225 cm dan radius kernel bahan bakar ditentukan 0,0250 cm. Dua parameter ini diinvestigasi karena sangat mempengaruhi performa moderasi neutron dalam teras VHTR. Efek radius kernel dan bahan bakar kompak dalam bahan bakar blok VHTR sebagai representasi dari teras aktif didiskusikan dalam makalah ini. Pengkayaan 235U sebesar 12% dan fraksi packing TRISO 0,29 dikerjakan di seluruh perhitungan dengan program transport Monte Carlo MCNPX dan pustaka data nuklir energi kontinu ENDF/B-VII pada suhu 1200K. Bahan bakar blok VHTR dimodelkan secara utuh dan presisi dengan kondisi batas reflektif. Hasil perhitungan memperlihatkan ketergantungan k∞ pada radius kernel berkurang seiring dengan berkurangnya radius bahan bakar kompak. Nilai k∞ hampir tidak bergantung pada radius kernel untuk radius bahan bakar kompak 0,4000 cm. Analisis menyimpulkan bahwa, kombinasi dua parameter ini adalah cara yang tepat untuk mendapatkan nilai faktor perlipatan neutron tak hingga yang diinginkan dari teras VHTR prismatik dengan fraksi packing dan pengkayaan bahan bakar yang spesifik.

Abstract

Metode pengobatan brachytherapy dalam bidang fisika medis dapat dilakukan dengan caramenempatkan sumber radioaktif dekat dengan jaringan sakit di dalam organ. Tujuan penelitian ini adalahuntuk mengetahui cara menentukan dosis serap brachyterapy kanker otak serta mengetahui pengaruhpada variasi jumlah seeds dengan dosis serap yang diterima. Ada beberapa sumber radioaktif yang dapatdilakukan pada metode brachyterapy, salah satunya I-125 radionuklida yang memiliki energi rendahsebesar 35,5 keV dan memiliki waktu paruh sebesar 59,4 hari. Pada penelitian ini dilakukan simulasibrachyterapi dengan software MCNPX. Hasil simulasi menunjukkan energi dosis serap masing masingsebesar 183.81 Gy untuk 10 seeds, 377,53 Gy untuk 20 seeds, 569,918 Gy untuk 30 seeds, 765,82 untuk 40seeds, dan 972,76 untuk 50 seeds besaran dosis serap tersebut ditunjukkan untuk jenis radioisotop I-125.Dari hasil tersebut diketahui bahwa adanya pengaruh jumlah seeds dengan dosis serap yang diterimapada brachyterapy kanker otak.

Abstract

Hasil studi awal yang dilakukan di Sekolah Menengah Kejuruan dalam naungan organisasi Badan Musyawarah Perguruan Swasta Kota Surakarta sebagai mitra dalam pelaksanan Pengabdian Kepada Masyarakat ini memiliki masalah terkait dengan pemahaman, keterampilan dalam menyusun, dan menggunakan lembar kerja.  Berdasarkan permasalahan tersebut, tim pelaksana kegiatan memberikan pelatihan pengembangan lembar kerja peserta didik model Project based learning (PjBL). Pelaksannaan Kegiatan pengabdian Masyarakat ini diikuti oleh 17 peserta yang berlansung selama satu bulan dengan empat kali pertemuan. Pertemuan pertama, peserta mengikuti pretes dan diberikan wawasan tentang konsep, karakteristik, dan prosedur pengembangan lembar kerja peserta didik PjBL. Pertemuan kedua peserta melakukan konsultasi analisis kebutuhan dan desain pengembangan lembar kerja PjBL. Pertemuan ketiga, peserta konsultasi draf produk lembar kerja dan pertemuan ke empat melakukan finalisasi, menikuti post tes, unggah produk lembar kerja, dan mengisi angket respons kegiatan. Kegiatan ini menghasilkan simpulan bahwa terdapat peningkatan pemahaman dan keterampilan guru dalam mengembangkan lembar kerja PjBL. Pelaksanaan pelatihan berlangsung sangat baik ditinjau dari penguasaan materi oleh para naras sumber, kejelasan sajian, penggunnaan bahasa, kedisplinan naras umber dan peserta, interaksi penyaji dengan peserta, ketepatan sajian, kesesuaian tema kegiatan, sarana dan prasana pelatihan. Namun perlu perbaikan dari aspek pelayanan panitia dan kelengkapan informasi panitia kegiatan.

Abstract

Currently, the pharmaceutical mathematics class has implemented the case method. However, many students still experience difficulties in organizing problem-solving in solving problems offered in the form of case studies. 70% of students have not focused on the problems offered during learning activities due to the lack of guidelines for solving the problems discussed. Therefore, it is necessary to conduct a needs analysis of student worksheets based on the case method to develop problem-solving skills. This study employed a quantitative descriptive method, involving lecturers teaching the pharmaceutical mathematics course and 68 students of the pharmacy study program at Universitas PGRI Adi Buana Surabaya as the research samples. Data collection techniques used were interviews and questionnaires with percentage formulas. The results of the interviews indicate that lecturers need to create student worksheets based on the case method to direct the learning process. Moreover, the questionnaire results showed that students really need case method-based student worksheets as a guide in solving problems in case studies.  This study is an initial study for the development of student worksheets based on the case-based pharmaceutical mathematics course to develop students' problem-solving skills.
