Geometri merupakan salah satu bidang kajian dalam kurikulum matematika sekolah karena geometri mempelajari berbagai konsep geometris yang digunakan dalam materi matematika lainnya dan berbagai bidang keilmuan lainnya. Teori berpikir geometri van Hiele menyatakan terdapat lima tahap berpikir siswa dalam bidang geometri, yaitu level 0 (visualisasi), level 1 (analisis), level 2 (deduksi informal), level 3 (deduksi), dan level 4 (rigor). Penelitian ini bertujuan untuk mengetahui dan mendeskripsikan kemampuan berpikir geometri van Hiele level 0 (visualisasi), level 1 (analisis), dan level 2 (deduksi informal) pada siswa sekolah menengah pertama ditinjau dari perspektif. Metode penelitian yang digunakan pada penelitian ini adalah deskriptif kualitatif. Intsrumen yang digunakan adalah tes yang setiap butir soalnya mewakili satu tahap berpikir geometri van Hiele dan wawancara. Tes dan wawancara dilakukan kepada 4 orang siswa SMP di salah satu sekolah di Jawa Barat yang terdiri dari 2 orang siswa perempuan dan 2 orang siswa laki-laki pada tahun ajaran 2019/2020 yang dipilih secara acak. Hasil penelitian menunjukkan keempat siswa berada pada level 2 (deduksi informal) berpikir geometri van Hiele. Siswa perempuan sedikit lebih baik dalam mengenali sifat-sifat bangun datar segiempat dibandingan siswa laki-laki. Dan tidak ada perbedaan yang menonjol antara kemampuan berpikir geometri van Hiele siswa perempuan dan siswa laki-laki.

This article discusses the democratic transition in Indonesia since 1998 until the end of the brief leadership of President Habibie, including previous analysis of the history and practice of democracy in Indonesia since 1945. The transfer of power from Soeharto to Habibie happened on May 21, 1998. In the 18 months of his leadership, Habibie was able to carry out important efforts in setting a foundation for democratic transition. Public freedom, freedom of the press, freedom of expression, and free speech were among Habibie’s achievements in opening the way for the process of democratization to continue. In the midst of the threat of the country’s collapse during that transition period, Habibie was relatively well able to defend the integrity of the Indonesian nation-state. His successors gained advantage from what had been put in place by Habibie. However, they have faced a number of problems, such as the procedural biases within democratic practice, incompatibility of presidential governance with the presence of many political parties, and gaps between the structure and function of high state institutions.DOI: 10.15408/sdi.v19i3.356

Artikel ini mengevaluasi indikasi praktik greenwashing yang dilakukan oleh perusahaan fashion ZARA-Inditex dalam menjalankan komitmen Sustainable Development Goal (SDG). Perusahaan tersebut merupakan salah satu perusahaan pertama yang bergabung dalam SDG tahun 2015. Sebagai pelopor industri fast fashion, komitmen ZARA-Inditex dalam SDG menghadirkan harapan baru tentang transformasi industri garmen dan pakaian yang lebih sustainable. Namun, para praktiknya, menjelang satu dekade dalam kerangka SDG, perubahan-perubahan yang dilakukan ZARA-Inditex terbatas pada aspek retorik dan simbolik. Berbagai praktik yang bersifat destruktif terhadap kemanusiaan dan lingkungan masih kerap dilakukan. Hal ini mengindikasikan bahwa perusahaan menggunakan SDG untuk melakukan praktik greenwashing. Penulis berargumen bahwa adanya praktik greenwashing ini menghadirkan risiko tidak tercapainya target SDG 12 (sustainable consumption and production pattern) pada tahun 2030.

The increasingly growing world economic developments of companies are competing to show each other the quality of their goods with other companies, and many consumers are beginning to invest in what areas are benefiting. Gold investment is a simple investment form. Because this investment can be done by anyone, whether they are from the educated or not, by investing gold in the form of gold coins and gold bullion. This study aims to determine simultaneously and partially promotional strategies, brand image and perceptions of users of gold savings at PT. Pegadaian (Persero) JOMBANG. The type of research used is associative. The population in this study 88.10 with a sample of 88 respondents. Data analysis techniques use multiple linear regression. The results showed simultaneously and partially promotion strategy, brand image and perception have a significant effect on purchasing decision. In the application of its marketing strategy should pay more attention to the brand image, given the image of gold jewelry brand on the consumer has not been embedded properly. This can be done for example by improving marketing and marketing communications programs to educate consumers about benefits and branding, through appropriate advertising strategies.

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk menumbuhkan kecerdasan logis-matematis warga belajar di salah satu Pusat Kegiatan Belajar Masyarakat (PKBM) di Kabupaten Bandung Barat, Provinsi Jawa Barat. Kegiatan ini dilatarbelakangi oleh hasil observasi bahwa pembelajaran matematika paket B belum mengoptimalisasikan media dalam proses belajarnya termasuk alat peraga. Hal ini disebabkan karena media belum terfasilitasi dengan baik, padahal belajar matematika dengan alat peraga dapat menumbuhkan tantangan bagi pembelajar termasuk alat peraga menara hanoi. Pengabdian terdiri dari beberapa tahapan yaitu observasi, pelaksanaan, dan evaluasi. Dalam pelaksanaan kegiatan warga belajar dibagi menjadi tiga kelompok dan mencoba mencari langkah minimum perpindahan dan menganalisis strategi yang harus digunakan untuk mencapai tujuan. Berdasarkan hasil angket kecerdasan logis-matematis didapatkan bahwa menara hanoi dapat menumbuhkan kecerdasan logis-matematis lebih dari 70% warga belajar, sehingga dapat dikatakan bahwa alat peraga ini cocok digunakan untuk menumbuhkan kecerdasan logis matematis dalam proses pembelajaran khususnya pada materi pola bilangan. This community service activity aims to foster the logical-mathematical intelligence of learning residents at one of the Community Learning Activity Centers (PKBM) in West Bandung Regency, West Java Province. This activity was motivated by the observation that package B mathematics learning had not optimized the media in the learning process, including teaching aids. This is because the media has not been well facilitated, even though learning mathematics with visual aids can create challenges for students, including the Hanoi tower props. The service consists of several stages: observation, implementation, and evaluation. In carrying out the activity, students are divided into three groups and try to find the minimum steps of movement and analyze the strategies that must be used to achieve the goal. Based on the results of the logical-mathematical intelligence questionnaire, it was found that the hanoi tower can foster logical-mathematical intelligence of more than 70% of the learning population, so it can be said that this teaching aid is suitable for growing logical-mathematical intelligence in the learning process, especially in number pattern material.

The Border of Responsibilities in Global Distribution of Aid: Ethical Issues and Challenges in Practices Pertiwi, Mutiara

This essay intends to analyse the debate about responsibility in the discourse of global justice. The topic is inspired by the statement of Thomas Pogge who argues that the minor outcome in promoting global justice is generated by a deep ethical problem on the question of responsibility rather than a technical problem such as taxation and liberalisation policy (2001a). He argues that many global problems would be solved if only the affluent countries perceived their roles in sending foreign aid as a responsibility and not as charity, which is how many communitarians perceive it. This ethical debate will be the concern of my essay. The main agenda is to find the most convincing argument for ethical guidance in the current world. Analysing through the lense of Bertrand Russell's (1961) parameter of ‘commendable ethics,' this essay validates Pogge's position that foreign aid from affluent states is part of negative responsibility and therefore commendable as an ethical guide in promoting global justice.
