It is aimed at analyzing students' creative thinking in solving arithmetical problems in State Junior High School 11 Malang, Indonesia. It is a qualitative approach with the type of case study where the number of the subjects were 6 students consisting of two students with high ability, two with moderate ability and two with low ability in mathematics. The results showed that the subjects under the category of high ability in mathematics did not show problems dealing with fluency, flexibility, and originality aspects, except in elaboration aspect. Students with moderate ability in mathematics still had difficulty in understanding mathematical problems, it may be seen from their steps in their less structured, detailed, and systematic solutions especially for the first problem. When they solved the problems given, their computation process was less careful, and trial and error strategies were mostly adopted in solving them. Students with low ability had difficulty in understanding the problems. Their ideas appearing in their mind were still trial and error in nature, not well structured, less systematic and detailed so that in solving and arranging the solution steps, they still encountered a lot of obstacles.

Research on graph associated with a finite algebraic structure has attracted many attentions. On the other hand, eccentric connectivity index is an interesting topic and many studies have been reported. For simple connected graph G, let e(v) denoted the eccentricity of vertex v and deg(v) denoted the degree of vertex v in G. Eccentric connectivity index of G is defined as the sum of all e(v)deg(v), for any v in G. We focus the study on determining eccentricity connectivity index of identity graph of cyclic group and finite commutative ring with unity. We present the exact formula for eccentricity connectivity index of identity graph of these two algebraic structures.

Dalam rangka meraih status Sekolah Adiwiyata Mandiri, SMPN 25 Kota Malang mengimplementasikan kurikulum berbasis lingkungan. Hal itu belum diimbangi dengan kompetensi guru dalam penyusunan perangkat pembelajaran berbasis lingkungan. Tujuan kegiatan pengabdian ini yaitu menambah pengetahuan dan keterampilan guru dalam mendesain pembelajaran berwawasan lingkungan dan menyusun perangkat pembelajaran berbasis lingkungan. Kegiatan ini dilaksanakan di SMPN 25 Kota Malang dengan jumlah peserta 11 guru dari 11 bidang studi. Metode yang diterapkan adalah workshop dan pendampingan yang dilakukan secara daring dan luring. Untuk mengukur keberhasilan kegiatan, dilakukan pretes-postes, observasi, dan wawancara dalam diskusi terpumpun. Hasil kegiatan pelatihan menunjukkan bahwa (1) terjadi peningkatan pemahaman guru dalam mendesain pembelajaran berwawasan lingkungan dan (2) terjadi peningkatan keterampilan guru dalam menyusun perangkat pembelajaran berbasis lingkungan. Kegiatan pelatihan penyusunan RPP berbasis lingkungan telah  meningkatkan pengetahuan dan keterampilan guru dalam Menyusun RPP berbasis lingkungan, sehingga dapat mendukung sekolah dalam meraih status Sekolah Adiwiyata Mandiri.

The purpose of this study was to improve students’ mathematical problem-solving skills on the material of numbers through the problem-based learning model in class VII-E of SMP Negeri 25 Malang. Classroom action research (CAR) was applied in this study. The study was carried out on 28 students of class VII-E of SMP Negeri 25 Malang. This research was conducted in 2 cycles. Results from the first cycle of classical completeness tests of 64.29% increased to 85.71% in the second cycle. In the first cycle, the highest problem-solving aspect was obtained in the aspect of understanding the problem with a percentage of 83.93% and categorized as complete, while the lowest problem-solving aspect was obtained in the re-examining aspect with a percentage of 59.29% and categorized as incomplete. In the second cycle, the highest problem-solving aspect was obtained in the aspect of understanding the problem with a percentage of 92.86% and categorized as complete, while the lowest problem-solving aspect was obtained in the re-examining aspect with a percentage of 70.24% and categorized as incomplete. It is possible to say that students’ ability to solve mathematical problems had increased in the class VII-E of SMP Negeri 25 Malang during the academic year of 2022/2023, allowing the problem-based learning model to be used as an alternative method to improve students’ ability to solve mathematical problems.

Pandemi Covid-19 membuat proses pembelajaran berubah dari pembelajaran luring menjadi pembelajaran daring. Dalam merespon perubahan tersebut, dibutuhkan inovasi dan pemanfaatan teknologi agar pembelajaran tetap berjalan dengan baik dan tujuan pembelajaraan tercapai, salah satunya dalam hal lembar kerja peserta didik. Sehubungan dengan itu, Ipteks bagi Masyarakat ini bertujuan untuk memberikan pendampingan penyusunan lembar kerja peserta didik elektorik (e-LKPD) berbasis kompetensi dengan menggunakan moda Google Form. Sasaran kegiatan ini adalah kepala sekolah dan seluruh guru SMPN 25 Kota Malang. Metode yang diterapkan adalah workshop dan pendampingan. Workshop disampaikan secara daring dengan materi yang berfokus pada LKPD, e-LKPD, dan pemanfaatan Google Form dalam penyusunan e-LKPD. Hasil kegiatan ini berupa keterampilan dalam menyusun e-LKPD oleh seluruh guru SMPN 25 Kota Malang. E-LKPD ini selanjutnya diterapkan pada semester genap tahun ajaran 2020/2021.
