Abstract

Previous studies have provided that when learning shapes for the first time, young children tend to use the prototype as the reference point for comparisons, but often fail when doing so since they do not yet think about the defining attributes or the geometric properties of the shapes. Most of the time, elementary students learn geometric properties of shapes only as empty verbal statements to be memorized, without any chance to experience the contepts meaningfully. In the light of it, a sequence of instructional activities along with computer manipulative was designed to support Indonesian third graders in constructing geometric properties of square, rectangle, and triangle. The aim of the present study is to develop a loval instructional theory to support third graders in constructing geometric properties of rectangle, square, and triangle. Thirty seven students of one third grade classes in SD Pupuk Sriwijaya Palembang, along with their class teacher, were involved in the study. Our findings suggest that the combination of computer and non-computer activities suppots third graders in constructing geometric properties of square, rectangle, and triangle in that it provides opportunities to the students to experience and to develop the concepts meaningfully while using their real experiences as the bases to attain a higher geometric thinking level.Key concepts: Geometric properties, rectangle, square, triangle, design research, realistic mathematics education DOI: http://dx.doi.org/10.22342/jme.4.2.414.160-171

Abstract

Sebagai pemimpin baru Makassar, Sultan Hasanuddin sedang menghadapi ancaman Kompeni Belanda yang semakin kuat. Dalam memperkuat kekuatan Makassar dari ancaman Kompeni Belanda, Sultan Hasanuddin memerintahkan orang Bugis Bone yang berstatus sebagai “budak” untuk bekerja menggali parit di sepanjang Pantai Makassar. Pekerjaan menggali parit itu telah mendorong Arung Palakka memimpin orang Bugis Bone keluar dari barisan Sultan Hasanuddin. Melalui Metode Sejarah dengan pendekatan nilai-nilai budaya danKepemimpinan Humanistik, kajian memperlihatkan, bahwa keluarnya Arung Palakka dari barisan Sultan Hasanuddin menjelang Perang Makassar adalah dipicu oleh implementasi kebijakan Sultan Hasanuddin dalam mempekerjakan Bugis Bone dalam menggali parit sudah di luar batas kemanusiaan. Mereka dipaksa untuk bekerja siang dan malam, tanpa diberikan istirahat dan perhatian yang memadai. Kebijakan seperti inilah yang membuat siri’ (harga diri) orang Bugis semakin terhina sehingga mendorong Arung Palakka memimpin orang Bugis Bone keluar dari barisan Sultan Hasanuddin agar orang Bugis Bone bisa merdeka dari kekuasaan Makassar. Dalam rangka mencapai tujuan itu, Arung Palakka meminta bantuan kepada Kompeni Belanda yang sudah lama mengincar Makassar. Bagi Sultan Hasanuddin berperang melawan Kompeni Belanda adalah perjuangan demi membela siri (harga diri) orang Makassar, karena Kompeni Belanda ingin menaklukkan Makassar. Arung Palakka dengan bantuan Kompeni Belanda berhasil memerdekakan orang Bone. Dari kekuasaan Makassar. Kompeni Belanda pun berhasil pula menaklukkan Makassar, sedangkan Sultan Hasanuddin sendiri berhasil pula membela siri (harga diri) orang Makassar secara terhormat sampai Makassar jatuh ke tangan Kompeni Belanda. Apabila Sultan Hasanuddin mampu memperlakukan orang Bone secara manusiawi dalam mengerjakan parit itu dan membangun komunikasi politik yang baik dengan para bangsawan Bugis, seperti Arung Palakka, maka Sultan Hasanuddin berpeluang menjadi seorang pemimpin yang tangguh di masa itu yang sulit untuk ditembus oleh Kompeni Belanda.

Abstract

Makalah ini dilatarbelakangi kebutuhan pembangunan pusat data (data center) sebagai faktor pemungkin kebijakan (enabling factor) perencanaan pembangunan, pertumbuhan ekonomi, dan menopang pemulihan dampak pandemi Covid-19. Sayangnya fasilitas pembangunan pusat data belum memenuhi standar pusat data hijau (green data center) sesuai standar internasional maupun nasional. Padahal penerapan standar pusat data hijau mampu menjadi wahana pemungkin percepatan pembangunan ekonomi berkelanjutan (sustainable economy). Pusat data hijau merupakan inovasi teknologi yang perlu diterapkan di Indonesia, khususnya di Kementerian PPN/Bappenas. Upaya ini sejalan dengan pendekatan pembangunan ekonomi berkelanjutan, transformasi digital, serta pengembangan pusat data nasional (PDN). Kerangka arsitektur dan desain pusat data hijau dikembangkan berdasar konsep peningkatan efisiensi pengembangan sistem pemerintahan berbasis elektronik (SPBE) yang melibatkan seluruh kementerian/lembaga dan pemerintah daerah. Konsep pengembangan PDN perlu menerapkan konsep pusat data hijau sehingga PDN dapat menjadi penggerak pembangunan ekonomi berkelanjutan. Pada akhirnya PDN dengan konsep green data center dapat meningkatkan utilisasi pusat data kementerian/lembaga dan pemerintah daerah. Guna menerapkan konsep green data canter, maka penulis mengajukan gagasan “PDN Hijau” dalam kerangka kerja berupa rencana aksi yang meliputi serangkaian kegiatan (1) penguatan kebijakan TKDN untuk perangkat pendukung PDN; (2) penyusunan standar pusat data hijau nasional; (3) pengadaan PDN Hijau sebagai bagian dari inisiatif SPBE; (4) kebijakan insentif bagi operasional PDN Hijau. Penerapan PDN Hijau dengan demikian dapat lebih memungkinkan percepatan pembangunan, membuahkan jejak karbon rendah, dan menggerakkan keunggulan kompetitif.

Abstract

The purpose of this study is to explain the Early Islamization Pattern in Southeast Asia: Its Contribution to Global Peace Efforts.  This study uses the Constructive Critical History Method.  This historical science is a new historical science that focuses on problem solving and finding solutions to problems  so that humans as historical actors can enjoy a better life in the present and in the  future. This research  finds that the “Pattern of Islamization of Trade and Civilizational Dialogue”  is the “Early Pattern of Islamization in Southeast Asia.”  This pattern  took place from the end of the 7th century to the beginning of the 16th century.  The agents of Islamization were Islamic traders or Islamic scholars who worked as traders. The weakness of this pattern is that it takes a long time. To achieve good results, this pattern requires the willingness and awareness of both the agents of Islamization and the indigenous population in undergoing the process of Islamization. This pattern does not have a negative impact on innocent Muslims and non-Muslims or those who live elsewhere. This pattern is carried out in a healthy and friendly manner that does not trigger cases of Islamophobia. Conclusion. This research contributes to overcoming the global impasse in addressing the crises, conflicts, wars, and disasters that emerged after COVID-19.
