Didasarkan penelitian terdahulu diperoleh fakta bahwa rendahnya input siswa, kualitas pembelajaran, dan dukungan dalam pembelajaran seperti belum tersedia bahan ajar yang memadai menjadi faktor penyebab rendahnya keterampilan berpikir kritis siswa SMK. Penelitian ini bertujuan untuk mengembangkan bahan ajar kimia SMK terintegrasi konteks kejuruan untuk meningkatkan keterampilan berpikir kritis. Model pengembangan bahan ajar mengadopsi model 4D dariBorg Gall. Penyusunan bahan ajar didasarkan studi pustaka dan pertimbangan rasional untuk merancang perencanaan pembelajaran dalam bentuk bahan ajar dan LKPD, serta asesmen untuk mengukur HOTS. Data penelitian diperoleh pada tahap pengembangan yang dilakukan melalui validasi ahli, dilanjutkan penerapannya melalui uji coba di sekolah untuk mengkaji peningkatan terhadap keterampilan berpikir kritis. Beberapa catatan dari validator telah diperbaiki, selanjutnya dilakukan uji coba skala kecil, ada perbaikan selanjutnya diujicoba skala besar sekaligus uji penerapan terhadap peningkatan berpikir kritis. Hasil penelitian menunjukkan bahwa N-gain untuk jurusan otomotif adalah 0,57 dengan kategori sedang, dan untuk jurusan Teknik Komputer Jaringan sebesar 0,56 keduanya dalam kategori sedang. Tiga buah bahan ajar yang telah tervalidasi hasil penelitian adalah: 1) bahan ajar materi asam-basa dari tim peneliti yang telah tervalidasi keberkaitannya dengan aspek konteks kejuruan dan aspek religius, 2) Dua buah Tesis dengan bahan ajar untuk program keahlian Teknik Otomotif dan Teknik Komputer Jaringan. Kedua bahan ajar telah teruji keefektifannya dalam meningkatkan keterampilan berpikir kritis.
The purpose of this research was to obtain an overview about the implementation of analytical chemistry instrument practicum and its learning outcome. The subject of this research was the students of chemistry education program of FMIPA UNNES who took Analytical Chemistry Instrument Practice course. Observations, interviews and field noteswerecarriedoutonpracticumrelatedtothemethodofassessment,theactivities of lecturer and students during class, as well as the practical manual. Meanwhile, the instruments that used for learning outcome were verbal pretest, an observation sheet to assess the practicum result, verbal questions when students reported observational data, and assessment sheet of practicum report and its rubric. The assessment was carried out in writing containing the mastery of the concept and knowledge of the procedure, the results of practicum observation data, and the practicum report. The practicum report was assessed without using criteria that are known to students, so that it lacks continuous feedback. In general, students do not understand the basic concepts related to practicum, were less able to explain what was done and were less able to explain the observed tendency, and even did not realize that the measurement results were far from expectation. In the case of writing report, there was a weakness in correlating the data of observations, discussions, and conclusions. It was necessary to pursue a practicum activity that in addition to developing basic skills in conducting experimentsandimprovingunderstandingofconcepts,alsodevelopsproblem-solving skill, and the formation of scientific attitudes, all of which are netted in well-prepared assessments.
Acid-base is a difficult subject to learn. It includes conceptually tricky words for the students. The theme is also considered difficult by teachers and prospective teachers in teaching and assessing student mastery. A misconception in chemistry topics is one of the biggest challenges for the teacher. This means that many students do not reach the learning objective. The acid-base question is considered one of the most challenging subjects, and there are many misunderstood concepts on this topic. Lack of understanding can be reduced by providing a simple and natural source of learning, such as a refutation text. This study aimed to determine the effectiveness of the refutation text to improve understanding of concepts and reduce misunderstanding in corrective learning on the acid-base topic for high school. There are six subtopics on acid-base content for high school. The test method used was the pre and post-project of a group, with a limited number of subjects. The test instrument used was the three-tiers of multiple choices for acid-base material (concept understanding’s test). The analysis result showed that 17 of 19 students had increased knowledge of concepts and decreased misconceptions. The concept change was significant, according to Mc Nemar Test. The value of effect size (ES) based on the Crochan-Q test was 4.12, a high category. It could be concluded that refutation text is effective enough to improve students' concepts and apply them to remedial learning.
Tim pengabdian dari Jurusan IPA Terpadu telah melaksanakan pengabdian kepada masyarakat di kawasan mangrove Tambakrejo, Semarang. Kegiatan ini bertujuan untuk menawarkan alternatif diversifikasi produk jasa wisata Edu-park Tambakrejo yang selama ini belum masif. Pengabdian yang dilakukan berupa pelatihan eco-print metode pounding dengan bahan dasar daun mangrove dan daun lainnya yang ada di sekitar Tambakrejo pada tanggal 2 Juli 2022. Proses pengabdian dilakukan dalam 3 tahap yaitu (1) persiapan, (2) pelatihan, dan (3) evaluasi. Kegiatan tersebut telah diikuti oleh warga PKK Merah delima sebanyaknya 15 orang. Hasil dari kegiatan pengabdian ini adalah peserta mampu melakukan teknik eco-print berbahan dasar daun dan daun dari tumbuhan lain di kawasan mangrove Tambakrejo. Produk eco-print yang dihasilkan berpotensi menjadi produk diversifikasi dari jasa wisata yang sudah ada saat ini. Diperlukan pendampingan lebih lanjut untuk peningkatan kualitas produk eco-print, serta pelatihan promosi dan pemasaran produk. The Integrated Science Department service team has conducted community service in the Tambakrejo mangrove area, Semarang. This activity aims to offer an alternative diversification of Tambakrejo Edu-park tourism products, which have not been massive so far. The service carried out is in the form of eco-print training on the pounding method with the basic ingredients of mangrove leaves and other leaves around Tambakrejo in July 2022. The service process is carried out in 3 stages, namely (1) preparation, (2) training, and (3) evaluation. Fifteen people of PKK Merah Delima attended this activity. This service activity results in participants carrying out eco-print techniques made from leaves and leaves from other plants in the Tambakrejo mangrove area. The resulting eco-print products have the potential to become diversified products from existing tourism services. Further assistance to improve the quality of eco-print products and promotion and product marketing training.
Abstrak. Pada saat ini, Indonesia sedang terkena musibah pandemi Covid-19, sehingga pemasyarakatan mengenai bahan-bahan lokal sebagai imunitas tubuh penting dikenalkan pada guru dan mahasiswa.
