Abstract

The Covid-19 pandemic caused the effects of learning activities from home. The phenomenon requires improvisation as a quick response so that the teaching and learning process continues to run and maintains learning motivation, especially in the scope of college. Activities that are assumed to be able to maintain motivation online is to provide tasks in the form of projects or Project Based Learning (PBL) which in this context does not mean eliminating face-to-face activities offline, but in the sense of providing sustainable projects in one semester and staying connected to lecture materials. This PBL is combined with Collaborative Learning (CL) in order to conduct a continuous project review. This research was conducted in Ma Chung University's Information Systems study program for Programming Language courses. The results of this implementation are evaluated by conducting FGD (Focus Group Discussion) in two stages. In the first stage there are some shortcomings that are then corrected by adding the obligation to upload the project to Github and intensify the involvement of lecturers. So in the second stage, FGD results show improved results. The results of the study are generic prescriptions, namely: the implementation of PBL accompanied by a mature plan and preparation, improvisation of PBL accompanied by the application of CL accompanied by the role of lecturers as facilitators need to be evaluated gradually, and the implementation of online collaboration can be applied because students can quickly adapt online.

Abstract

Mahasiswa baru di kampus yang berbasis pendidikan vokasi memiliki background pendidikan yang berbeda. Kebanyakan dari mereka berasal dari sekolah menengah atas atau sederajat yang jurusannya bukan IPA. Hal ini menyebabkan mata kuliah Mikrobiologi Dasar di semester satu termasuk ke dalam mata kuliah yang sulit dipahami oleh mahasiswa dengan background di luar IPA. Selain itu, minimnya lembar kerja mahasiswa yang bisa mengasah daya pikir mereka adalah penyebab rendahnya hasil belajar pada mata kuliah ini. Hasil observasi menunjukkan banyak mahasiswa yang cukup kesulitan dalam memahami materi nutrisi mikroorganisme. Tujuan dari penelitian ini adalah untuk mengembangkan Lembar Kerja Mahasiswa (LKM) pada materi Nutrisi Mikroorganisme berbasis High Order Thinking Skill (HOTS). Model pengembangan yang digunakan dalam penelitian ini adalah 4-D dari Thiagarajan dengan mengadopsi tiga tahapan yaitu Define (Pendahuluan), Design (Perencanaan) dan Develop (Pengembangan). Hasil pengembangan menunjukkan bahwa 78% LKM dinilai layak. Kebahasaan LKM sebesar 72,5% dikategorikan layak dan penyajiannya sebesar 76,6% dikategorikan layak. Kegrafikan LKM sebesar 82,5% dikategorikan sangat layak. Hasil uji keterbacaan dari LKM adalah 71,78% dengan kriteria layak dan respon mahasiswa dalam menggunakan LKM, 90% menyatakan sangat baik.

Abstract

Abstrak Pandemi COVID–19 memberikan dampak di semua aspek kehidupan salah satunya adalah aspek pendidikan. Seluruh pengajar di semua jenjang pendidikan harus bisa mengajar dalam kondisi tidak bertatap muka secara langsung dengan peserta didik yang diajar. Hal ini tentunya juga akan berpengaruh pada sistem pengajaran saat di kelas yang biasanya dilaksanakan secara offline maka sekarang harus dilaksanakan secara online. Materi ajar yang disampaikan juga harus dimodifikasi agar kompetensi yang didapat oleh peserta didik tetap sama meskipun tidak ada pertemuan face to face. Pembelajaran dengan kelas praktikum juga terkadang harus dilakukan oleh peserta didik sendiri di rumah mereka masing–masing. Oleh sebab itu pengajar harus mampu membuat bahan ajar yang bisa dipahami dengan cukup baik oleh perserta didik. Selain itu, bahan ajar tersebut sebaiknya mendapat tanggapan yang baik juga dari peserta didik. Penelitian ini bertujuan untuk mendeskripsikan respon mahasiswa terhadap modul praktikum berbasis inkuiri terbimbing pada pembelajaran daring mata kuliah teknologi pengolahan limbah. Penelitian ini menggunakan instrumen angket atau kuesioner yang disebar ke 30 mahasiswa untuk mengetahui bagaimana respon mereka terhadap nilai kepraktisan penggunaan modul praktikum daring mata kuliah teknologi pengolahan limbah.

All educators in all levels of education must be able to teach in conditions that are not being able to talk face to face with the students. This will also affect the teaching system when in class which is usually carried out offline so now it must be carried out online. The teaching materials delivered must also be modified so that the competencies gained by students remain the same even though there is no direct meeting. Learning with practical classes also sometimes has to be done by students themselves in their homes. Therefore, educators must be able to make teaching materials that can be understood quite well by students. In addition, these teaching materials should also get a good response from students. This study aims to describe student responses to guided inquiry-based practical modules in online learning for Teknologi Pengolahan Limbah course. This study uses a questionnaire instrument which is distributed to 30 students to find out how they respond to the practical value of using the online practicum module for Teknologi Pengolahan Limbah course. The results showed that the average answer choices were 90% or included in the "very good" category for student responses to the practical value of using the online practical module for Teknologi Pengolahan Limbah course. Keywords : guided inquiry, learning, modules, response, teknologi pengolahan limbah.
