Abstract

Jiwa kewirausahaan seharusnya dapat dikembangkan sejak dini. Pengembangan jiwa kewirausahaan ini dapat dilakukan dengan beberapa cara, salah satunya adalah praktik pembuatan produk dengan bahan-bahan sekitar. Pengabdian kepada masyarakat ini bertujuan untuk menumbuhkan jiwa kewirausahaan dengan mengembangkan produk sabun dengan menggunakan kulit buah naga. Kulit buah naga yang selama ini tidak berguna dan hanya dibuang, dapat dimanfaatkan dalam pembuatan sabun. Sabun yang dibuat dapat berupa sabun cair, maupun sabun padat. Namun, fokus dalam pengabdian ini adalah pembuatan sabun padat. Pengadaan bimbingan teknis ini karena masih minimnya praktik dalam mata pelajaran kewirausahaan di sekolah. Selain itu, program ini sebagai wadah untuk mensosialisasikan kegunaan dari kulit buah naga tersebut. Strategi yang digunakan adalah dengan menyampaikan sedikit teori dilanjutkan dengan praktik secara demonstrasi. Hasil yang didapatkan dari program ini adalah kegiatan ini diikuti oleh 40 orang peserta didik dan dihasilkan produk sabun padat kulit buah naga. Produk ini dapat dikemas dengan baik agar dapat dipasarkan secara luas.

Abstract

This program evaluation is intended to describe the results of the comprehensive examination program for prospective teachers in all science fields. The results of this program evaluation are expected to make a specific contribution to the sustainability of the comprehensive examination program being held and are expected to contribute to education in general. This program evaluation uses the CIPP (Context, Input, Process and Product) evaluation model. Data sources for this program evaluation consist of documents and human resources. Based on the results of a thorough evaluation of the comprehensive examination program, it can be concluded that recommendations to improve the effectiveness and sustainability of this program are very important. Evaluations covering context, input, process and product aspects show that there are several areas that need to be improved and improved. An effective and sustainable comprehensive examination program is not only an evaluation tool, but also an integral part of their academic and professional career development. With a holistic and sustainable approach, study programs can ensure that comprehensive exams provide maximum benefits for students and educational institutions as a whole.

Abstract

Development of Interactive Learning Multimedia Based on Android on Electrolyte and Non-Electrolyte Solution Materials]. This research aims to find out the level of eligibility and response of learners to android-based interactive learning multimedia on electrolyte and non-electrolyte solution materials developed. The research was conducted in March-June 2021 at Bengkulu University and State High School 3 Bengkulu City. The development model used, namely the 4-D (Four-D) model from Thiagarajan which is limited to the developing stage. The sample used in the small-scale trial was one class XI MIPA 2 totaling 36 people. Research data is obtained from the validation questionnaire of material experts and media experts as well as the response questionnaire of learners. From the results of the research obtained the level of feasibility of interactive learning multimedia in material aspects by 89.4% and media aspects by 94.2%, so that interactive learning multimedia can be categorized as very valid. The results of learners' responses to multimedia interactive learning in small-scale trials obtained a percentage of 81.52% with very interesting categories. The results of this study show that android-based interactive learning multimedia that has been developed is very feasible for use in the learning process.

Abstract

The micro-scale approach in organic chemistry learning offers an innovative solution to enhance the effectiveness of the teaching and learning process while supporting the Sustainable Development Goals (SDGs). This study aims to describe the implementation of the micro-scale approach in the curriculum of an organic chemistry course at a higher education institution. This approach emphasizes the use of small quantities of chemicals, simple laboratory equipment, and eco-friendly techniques to minimize laboratory waste, operational costs, and negative environmental impacts. The research method involves qualitative analysis to evaluate the effectiveness of this approach in terms of learning outcomes and its relevance to the SDGs, particularly those related to quality education. The results reveal that the micro-scale approach has not yet been implemented in organic chemistry learning. However, organic chemistry lecturers and students have a general understanding of the concept of the micro-scale approach. Moreover, both lecturers and students recognize that the micro-scale concept aligns with the objectives of sustainable development. This study concludes that the micro-scale approach is an innovative and effective strategy to support sustainability-oriented organic chemistry learning. The implementation of this approach is expected to serve as a replicable learning model across various educational institutions, contributing to broader SDGs achievements
