<![CDATA[Cabbage (Brassica oleracea) is one of the vegetable wastes that is often produced by the Amahami market, Bima City. With its easy-to-wilt nature and high water content, cabbage causes it to rot quickly, which will impact environmental problems. Processing market waste certainly requires sustainable management. One model of waste management is to use it as feed. This research aims to determine the effect of giving cabbage waste on the increase in the population of earthworms (Eudrilus eugeniae). The research was carried out in Bima City, Ule Village, Asakota District, Tolotongga Environment. The type of this research is experimental. The research design was a Completely Randomized Design (CRD) with four treatments and ten replications. The parameter observed was the increase in the number of earthworms, analyzed using One Way Anova and followed by Duncan's Multiple Range Test (DMRT). The results of the research showed that giving cabbage waste (Brassica oleracea) as feed had a significant effect (0.009<0.05) on increasing the population of earthworms (Eudrilus eugeniae). The treatment with the highest results was P1 (50 grams of cabbage), with an average number of worms of 367.30.]]>

<![CDATA[Facing the challenges of the 21st century, learning must be able to produce learners into creative individuals to solve problems. The ability to think creatively is closely related to a person's character or creative habits; good character can trigger good skills. This study aims to determine how applying the Contextual Teaching and Learning (CTL) model improves students' creative disposition and creative thinking skills. The method in the form of Quasi-Experimental Design uses Pre-test and post-test control Group Design on as many as 64 X students at one of Aikmel State High Schools, NTB. The 32-person experimental class used the CTL model of the guided inquiry method, and the 32-person control class of the discussion method. Data on students' creative dispositions were collected using creative disposition questionnaires given before and after good treatment in both groups. Data on students' creative thinking skills were collected with a creative thinking skills test developed referring to the Torrance Creative test. The data were obtained and analyzed using the t-test to determine the comparison of the two classes and the N-gain test to see the improvement in each class. The results showed significant differences in creative disposition and creative thinking skills between the experimental class and the control class. Increased creative disposition in the experimental class with an N-gain of 0.45 means an increase in the medium category and an N-gain of 0.08 in the control class, which means an increase in the low category. Meanwhile, the creative thinking skills of experimental class students amounted to an N-gain of 0.48, which means there was an increase in the medium category, and an N-gain of 0.05 in the control class, which means there was an increase in low theory. This study concludes that applying the CTL model can improve creative disposition and thinking skills.]]>

<![CDATA[Basic teaching skills are skills that prospective teacher students must have. This research aims to determine the level of basic teaching skills in teaching practice among Biology Education students taking the Micro Teaching course in class A group B in 2022/2023. Data was collected from observations of student teaching practices through peer teaching. The instrument used is an observation sheet derived from indicators of eight aspects of basic teaching skills, with answer choices using a Likert scale. The data was analyzed descriptively by calculating the average score obtained by each indicator on the eight aspects of basic teaching skills observed. The observation results show that students' average in all aspects of basic teaching skills is very good. In contrast, the results of observations on the indicators for each element of skills show categories that vary from quite good, good, and very good. It can be concluded that students have been able to apply the eight aspects of basic teaching skills in teaching practice very well. However, if we look at the indicators for each aspect of skills, there are still students in the quite good and good categories.]]>

<![CDATA[Keputusan Bersama Menteri Pendidikan dan Kebudayaan dan Kepala Administrasi Kepegawaian Negara No. 0433/P/1993 dan No.25 Tahun 1993 tentang petunjuk Pelaksanaan Jabatan Fungsional Guru dan Angka Kreditnya mengharuskan adanya poin pengembangan profesi guru melalui kegiattindakan kelas (PTK). Disisi lain para guru belum terbiasa melakukan hal tersebut, sehingga berakibat pada terhambatnya karier guru terutama setelah mereka mencapai pangkat/golongan IVa ke atas. Sejalan dengan fenomena tersebut maka permasalahan dalam pengabdian pada masyarakat ini adalah: Bagaimana tehnik menjadikan kegiatan penelitian di kalangan guru menjadi suatu kebutuhan dan kebiasaan yang terus menerus ? Untuk menjawab persoalan tersebut maka digunakan metode kegiatan berupa pendampingan dengan cara diskusi, tanya jawab dan tutorial pada guru-guru, dengan mengambil lokasi kegiatan SMP Negeri 11 Mataram. Kegiatan ini dirasakan sangat bermanfaat bagi para peserta (para guru) dalam memunculkan ide-ide baru bagi kegiatan penelitian yang dapat dikembangkan guru, menambah pemahaman tentang cara menulis proposal PTK serta meningkatkan kepercayaan diri untuk dapat melakukan penelitian di sekolah. Berdasarkan atas keberlangsungan pelaksanaan dan evaluasi yang telah berjalan, dapat disimpulkan bahwa kegiatan ini berhasil dengan baik dengan manfaat sangat besar. Guru semakin menyadari pentingnya melakukan kegiatan penelitian sebagai bentuk pengembangan karya ilmiah yang menjadi kewajiban dan tugas pokoknya. Kegiatan pendampingan ini juga bermanfaat bagi guru-guru IPA SMP Negeri 11 Mataram dalam pengembangan prose belajar mengajar.]]>
