Abstract

The BOOST SD (Optimal Learning with Educated Students) program is implemented at SD Negeri Botok, Magetan, to improve the reading literacy skills of students in grades 1 to 3 with low literacy levels. This program lasts three months, from September to November 2023, with stages of need identification, development of learning tools, implementation, and evaluation. The methods used include initial observation, discussion with teachers, and the development of tools such as textbooks, visual presentations, and assessment instruments. The evaluation was carried out through pre-test and post-test, showing a significant improvement in students' reading ability, especially in letter recognition, word reading, and sentence reading. The program emphasizes the importance of targeted interventions and can serve as a practical model for addressing literacy challenges in other primary schools.

Abstract

SIBEL (Tutoring System) is a community service program to assist 5th and 6th-grade students of SD Negeri Botok, Karas District, Magetan Regency, in preparing for the ANBK (Computer-Based National Assessment) exam. This program is focused on improving students' literacy and numeracy skills through structured guidance. The purpose of this program is to create a learning awareness environment at SD Negeri Botok, especially for 5th and 6th-grade students, to help 5th and 6th-grade students improve their ability to do literacy and numeracy problems and to help 5th and 6th-grade students prepare well for the ANBK exam. The implementation of the program took place from 4 September to 30 November 2023 and involved the use of pretest and post-test to measure the improvement of students' abilities. The results of the study showed a significant improvement in students' literacy and numeracy skills, as well as the creation of a learning-conscious environment that supports the success of the program. This SIBEL program has proven effective in preparing students for the ANBK exam.

Abstract

Program Kuliah Kerja Nyata Tematik (KKN-T) Asistensi Mengajar yang dilaksanakan di SD Negeri Botok, Magetan, bertujuan untuk meningkatkan kualitas pendidikan melalui dua program utama, yaitu BOOST (Belajar Optimal dengan Siswa Terdidik) dan Sibel (Sistem Belajar Bimbingan). Program BOOST difokuskan pada peningkatan kemampuan membaca siswa kelas 1, 2, dan 3, serta pemberantasan buta aksara, sedangkan Sibel ditujukan untuk mempersiapkan siswa kelas 5 dan 6 dalam menghadapi ujian ANBK dengan mengasah kemampuan literasi dan numerasi mereka. Evaluasi pre-test dan post-test yang dilakukan dalam program BOOST menunjukkan adanya peningkatan signifikan dalam kemampuan membaca siswa, mencakup pengenalan huruf, membaca kata, kalimat, membaca nyaring, dan pemahaman membaca. Peningkatan ini mencerminkan keberhasilan mahasiswa KKN-T dalam memberikan bimbingan yang efektif. Meskipun program ini menghadapi tantangan seperti rendahnya minat belajar peserta didik dan kesulitan dalam mengerjakan soal matematika, solusi yang diterapkan, seperti penyusunan soal latihan menarik dan menciptakan suasana belajar yang nyaman, berhasil meningkatkan keterampilan siswa. Secara keseluruhan, kedua program ini terbukti efektif dalam meningkatkan keterampilan literasi dan numerasi siswa SD Negeri Botok, serta memberikan kontribusi positif dalam mempersiapkan mereka untuk ujian ANBK.

Abstract

The Library Revitalization and Administration Program (REVPUS), which was carried out at SD Negeri Botok, Karas District, Magetan Regency, aims to increase students' interest in reading and knowledge insights through reviving the library by rearranging facilities and student involvement in library management. In its implementation, students in grades 4, 5, and 6 are child librarians who manage the library administration system and are involved in book-lending activities. The revitalization includes the renovation of library rooms that were previously unmaintained, the grouping of books according to categories and levels of difficulty, and the addition of creative designs to increase the attractiveness of the library. In addition, open reading classes involving students in reading and borrowing books are also held to encourage increased interest in reading. The evaluation of the program through a questionnaire showed positive results, with high responses from teachers and students regarding the library's comfort, orderliness, and attractiveness. Despite facing obstacles such as a lack of book collections and the initial condition of the library being poorly organized, this problem was successfully overcome by rearranging shelves and adding relevant books. To ensure sustainability, this program requires a more varied procurement of books and active support from schools and communities.

Abstract

Abstrak Pencemaran lingkungan akibat pembuangan limbah berwarna seperti methylene blue menjadi perhatian serius karena sifatnya toksik, karsinogenik, dan sulit terurai. Fotokatalis berbasis semikonduktor seperti TiO2 dikenal efektif untuk memecah senyawa kompleks menjadi senyawa yang lebih sederhana, namun memiliki keterbatasan dalam menyerap sinar tampak. Sehingga diperlukan modifikasi TiO2 dengan material rGO yang bertujuan meningkatkan efisiensi degradasi di bawah sinar tampak. Penelitian ini bertujuan menganalisis efektivitas penambahan rGO pada komposit TiO2/rGO sebagai pendegradasi pewarna methylene blue dalam sinar tampak. rGO direduksi dari GO yang disintesis menggunakan metode Hummer’s termodifikasi dari arang kelapa, kemudian dikompositkan dengan TiO2 menggunakan metode hidrotermal autoclave dengan variasi massa rGO 45, 60, 75, 90, dan 105 mg. Selanjutnya dikarakterisasi menggunakan SEM dan UV-Vis. Hasil SEM menunjukkan partikel TiO2 menyelimuti lembaran rGO dengan distribusi partikel pada komposit TiO2/rGO-105 sebesar 214,12 nm. Nilai energy band gap terkecil pada TiO2/rGO-105 sebesar 2,26 eV. Efisiensi degradasi sebesar 99,8% pada menit ke-105. Hasil menunjukkan bahwa penambahan rGO dalam komposit TiO2/rGO dapat meningkatkan efektivitas fotokatalis di bawah sinar tampak.  Abstract Environmental pollution due to the disposal of colored waste such as methylene blue is a serious concern due to its toxic, carcinogenic, and difficult to decompose properties. Semiconductor-based photocatalysts such as TiO2 are known to be effective in decomposing complex compounds into simpler compounds, but have limitations in absorbing visible light. Therefore, modification of TiO2 with rGO material is needed to increase degradation efficiency under visible light. This study aims to analyze the effectiveness of adding rGO to TiO2/rGO composites as a degrader of methylene blue dye in visible light. rGO was reduced from GO synthesized using the modified Hummer's method from coconut charcoal, then composited with TiO2 using the autoclave hydrothermal method with variations in rGO mass of 45, 60, 75, 90, and 105 mg. Furthermore, it was characterized using SEM and UV-Vis. The SEM results showed that TiO2 particles covered the rGO sheets with a particle distribution in the TiO2/rGO-105 composite of 214.12 nm. The smallest energy band gap value in TiO2/rGO-105 is 2.26 eV. The degradation efficiency is 99.8% at the 105th minute. The results show that the addition of rGO in the TiO2/rGO composite can increase the effectiveness of the photocatalyst under visible light. Keywords: Photocatalyst, Methylene Blue, TiO2, GO, rGO, Hydrothermal Autoclave.
