Abstract

This study aims to produce an organic compound textbook for the Seaweed Agribusiness Expertise Program at vocational high schools. The research method used is a mixed method with an educational reconstruction model that focuses on content structure analysis. Content structure analysis is carried out through literature studies, subject matter clarification, and concept modification and refinement. Validation by experts was carried out to see the suitability of the indicators and learning objectives, as well as the suitability of the textbook with the BSNP criteria. The characteristics of the resulting textbook use problem-based learning syntax. The textbook consists of four chapters and several sections related to the expertise program, in the form of knowledge, information, and applications about seaweed. The assessment of the textbook includes the suitability of the learning objectives with the text in the textbook. The results of the expert assessment of the textbook show the suitability of the indicators with the learning objectives and the suitability of the learning objectives with the textbook text. All indicators and learning objectives obtained a CVR value calculated above the critical CVR value of 0.622 for seven validators, namely CVR = 1.00, so that it can be accepted or declared valid. The suitability of the textbook with quality criteria based on BNSP includes the aspects of content feasibility, presentation feasibility, language and graphics with percentages of 86.68%, 94%, 100%, and 100%, respectively. The results of this study indicate that the developed organic compound textbook has met the validity criteria and is feasible for use in learning in vocational high schools with the Seaweed Agribusiness Expertise Program. This textbook is expected to be a reference for vocational high school students to improve their understanding of the organic compounds found in seaweed so that they can be utilized in seaweed cultivation and processing practices.

Abstract

Students need computational thinking skills to help them face global challenges with rapid technological development. For this reason, teachers must be able to implement CT in learning by paying attention to students' interest in learning, one of which is using educational games. Designing CT-integrated educational games requires appropriate strategies such as mastery learning. This study aims to analyse the development of educational game design using mastery learning strategies so that it can provide an overview to educators in developing the media to improve students' CT skills. This research uses a qualitative descriptive method. The data obtained was analysed bibliometrically using the VOS Viewer application. The VOS Viewer analysis shows that there is a connection between game design, computational thinking, and mastery learning that began in 2016. The results also show that there are 4 things that become the basis for designing educational games, namely cognitive, motivational, affective, and sociocultural perspectives

Abstract

Teacher certification is a fulfillment of professional competence. In Bengkulu City, many junior high school science teachers are still uncertified. Therefore, mapping is needed to see the number of the junior high school science teachers who are certified and uncertified in Bengkulu City. This research uses descriptive qualitative methods through observation and interviews. The results showed that 109 junior high school science teachers in Bengkulu City are already certified and 65 are uncertified. There are 114 junior high school science teachers in Bengkulu City who are civil servants and 60 non-civil servants who teach in 47 junior high schools in Bengkulu City. Meanwhile, teachers who are called to join the in-service certification program must pass the Teacher Competency Test (UKG), which causes some teachers to fail to follow the next stage in the in-service teacher training program (PPG). Therefore, in order to fulfill the mandate of the Teachers and Lecturers Law 2015, it is recommended that the Bengkulu City Goverment and the Ministry of Education and Culture implement an accelerated teacher certification program to ensure that teachers are professional.

Abstract

Akar wangi (Vetiveria zizanioides) merupakan salah satu komoditas ekspor unggulan Indonesia. Indonesia menempati posisi sebagai produsen terbesar kedua setelah Haiti dalam ekspor minyak akar wangi (vetiver oil) di dunia, bahkan pada tahun 2010 sempat menjadi pengekspor utama akibat bencana di Haiti. Di sisi lain, pasar produk pertanian dari hari ke hari semakin mengglobal dan menyaratkan perhatian lebih dari produsen. Seiring meningkatnya perdagangan global, standar mutu produk pertanian menjadi aspek krusial untuk mengakses pasar ekspor. Keingintahuan konsumen di negara pengimpor mengenai standar produksi di negara produsen serta keterlacakan (traceability) dalam rantai pasokan menjadi semakin relevan dalam perdagangan internasional. Petani, pengolah, dan eksportir harus familier dengan standar-standar tersebut serta mampu menerapkannya dalam budidaya dan pengolahan jika ingin tetap bersaing di pasar dunia. Oleh karena itu, diperlukan langkah konkret bagi pelaku industri minyak akar wangi untuk bertahan di pasar global, salah satunya melalui produksi minyak akar wangi organik (organic vetiver oil) yang bersertifikat internasional. Penelitian ini menggunakan lahan seluas 1 hektar sebagai plot demonstrasi (demonstration plot/demplot) budidaya akar wangi organik yang ditanam secara tumpang sari dengan tanaman kentang. Pembudidayaan dilakukan dengan sistem pertanian organik terpadu dan terintegrasi, mulai dari penanaman, pemupukan, penyiangan, pengendalian hama dan penyakit, hingga proses pemanenan dan pengolahan produk. Hasil penelitian menunjukkan bahwa kualitas minyak akar wangi organik telah memenuhi persyaratan yang ditetapkan. Parameter keunggulan meliputi nilai rendemen yang mencapai > 50% (berbanding < 50% pada non-organik), penampakan fisik akar yang lebih bersih dan lebat, serta hasil uji SNI dan residu pestisida yang memenuhi standar keamanan pangan.
