In order to prepare students who are able to reason at a high level as well as skilled in using technology, it is necessary to hold a training activity for teachers to design and implement HOTS-oriented learning by utilizing Edmodo as a technology-based teaching medium. The training consisted of material reinforcement (the use of Edmodo, HOTS-oriented learning, preparation of HOTS questions) and workshops (teachers were guided in creating accounts and utilizing the features available in Edmodo as well as developing HOTS-oriented learning modules). The participants were able to inform more about the HOTS after training and about 18 teachers agreed that the participants had been able to construct their learning. In addition, there was also an increase in the ability of teachers to use Edmodo as a technology-based learning media. Of the 22 questionnaires submitted, 14 participants agreed that their understanding of Edmodo had increased and more than 90% of the training participants had been able to understand HOTS-based learning. In addition, although not many participants understand the use of Edmodo, the percentage was still above 50%. In general, 90% of the training participants believe that HOTS-based learning can be applied to the Edmodo as a learning medium.

Rubella is a common cause of childhood rash and fever. It is typically a mild infection but it can be serious condition in pregnant women, as it may cause Congenital Rubella Syndrome (CRS) in the fetus. The study aimed to model and analyze it in order to get picture about the dynamics of the rubella virus transmission. The paper discussed two models of rubella transmission involving child-bearing age women and newly born infants of infected mothers. The models are SEIR-IR without seasonality and SEIR-IR with seasonality. The results from the first model showed that a pitchfork bifurcation occurred in the dynamics of the solution of the system with constant infection rate and the increase of the infection rate value do not make impact to the incidence of rubella among infants. The second model involving seasonality gave interesting dynamics where big seasonality may lead to a more complex dynamics of the solution.

Students were demanded to be a creative problem solver in the career world. A mathematical learning following an inquiry-based learning approach and integrating mathematical tools was developed in this study. Students constructed original solutions about trigonometry ratio by using a clinometer and a meter as mathematical tools in allowing creative thinking. The product was designed through ADDIE methodology and applied to two classes in a Senior High School. A pre-test and post-test design measured cognitive knowledge as creative thinking variable. The result showed that this product with using mathematical tools was feasible and successful in enhancing students’ creative thinking. Inquiry-based learning was developed by involving three main components: providing students with a contextual mathematical problem-solving activity; involving student in an open-ended investigation with using a clinometer and a meter as mathematical tools to promote their creative thinking in creating original solutions; motivating students to build their own knowledge. This inquiry-based learning which had been developed significantly influenced students’ pre-knowledge scores. It could be concluded that creative thinking contributed, too. A recommendation for mathematics teachers in teaching mathematics was to involve students in problem-solving activity that facilitated them to conduct open-ended investigation whereas they could construct their own knowledge in building an original solution.

Kasus kejahatan perdagangan orang atau manusia merupakan kasus yang sangat serius dan seharusnya juga ditangani dengan cara luar biasa serta pelakunya dihukum dengan seberat-beratnya. Namun penanganan kejahatan ini bukanlah segampang membalikkan telapak tangan, karena faktor-faktor penghambat seperti peraturan perundang-undangan, aparat penegak hukum juga budaya serta kesadaran hukum masyarakat. Permasalahan penelitian ini adalah bagaimana kebijakan kriminal dalam pencegahan dan penanggulangan kejahatan perdagangan manusia (human trafficking) di Indonesia dan faktor-faktor apa yang menjadi penyebab terjadinya kejahatan perdagangan manusia (human trafficking) ditinjau dari perspektif kriminologis. Penelitian ini tergolong penelitian yuridis normatif. Sumber data yang digunakan adalah data primer dan data sekunder. Berdasarkan hasil penelitian ditemukan jawaban, bahwa kebijakan kriminal dalam pencegahan dan penanggulangan kejahatan perdagangan orang atau manusia di Indonesia dilakukan dengan menggunakan dua cara pendekatan, yaitu melalui sarana penal dan non penal dengan melakukan tindakan preventif dan represif.

COVID-19 has caused unprecedented disruption to mathematics teacher education worldwide. This paper is anchored in our learnings from the experiences of teacher educators at four major universities from the Association of Southeast Asian Nations as they dealt with changes in their programs' delivery triggered by the pandemic, and raises challenges that remain for the futures of post-pandemic mathematics teacher education. Here, we use the two ethical constructs of responsiveness and responsibility to guide actions in response to a crisis, in order to discuss a range of decisions the participants made to respond to the crisis. Behind their initial response to the emergent conditions, the participants were concerned about maintaining the continuity of their students' education. Further, we identify remaining challenges for mathematics teacher educators to re-imagine their curriculum, teaching, assessment, and equitable access towards a more relevant, productive, and equitable mathematics teacher education. This study adds to the rapidly increasing literature on the effect of the pandemic on mathematics education in the following three ways: (1) here we take a comprehensive view of the disruptions instigated by the pandemic;, (2) we pay special attention to issues of equity; and (3) we address concerns about possible and desirable post-pandemic futures.

Pemanfaatan Teknologi Informasi dan Komunikasi (TIK) dalam bidang pendidikan diantaranya adalah untuk pembuatan media pembelajaran. Namun pada umumnya yang digunakan adalah media pembelajaran presentasi yang bersifat satu arah. Agar pembelajaran menarik diperlukan media pembelajaran interaktif yang bersifat dua arah sehingga guru dapat mengetahui umpan balik dari apa yang dipelajari peserta didiknya. Pascasarjana Universitas Negeri Surabaya, khususnya Tim Pengabdian Kepada Masyarakat (PKM), berusaha merintis kerjasama dengan Dinas Pendidikan Kabupaten Lombok Timur. Rintisan kerjasama tersebut dilakukan dengan mengadakan kegiatan PKM dengan sasaran guru-guru sekolah menengah seperti Sekolah Menengah Pertama (SMP), Sekolah Menengah Atas (SMA), atau Sekolah Menengah Kejuruan (SMK) dalam pembuatan media pembelajaran interaktif bagi guru-guru di Kabupaten Lombok Timur.Kegiatan pelatihan berjalan lancar dan peserta merasakan manfaat pelatihan pembuatan media pembelajaran interaktif karena selama ini hanya bersifat satu arah. Namun karena pelatihan ini baru pertama kali dikenal peserta maka waktu yang disediakan masih terasa kurang. Tetapi hal ini dapat diatasi dengan melalukan konsultasi secara online. Peserta pelatihan adalah para Kepala Sekolah sehingga diharapkan dapat menyampaikannya pada guru-guru di sekolahnya.
