This study aims to determine the application of the Jigsaw type cooperative learning model to students and whether or not there is an increase in learning outcomes in economic subjects. Jigsaw cooperative learning is learning that focuses on discussion by groups of experts and groups of origin. Discussions conducted by students aim to understand the material being studied. The problem posed is about economic subject matter. This research is a classroom action research consisting of two cycles. This classroom action research is focused on improving student learning outcomes. The results showed that the application of the Jigsaw type cooperative learning model was able to improve the learning outcomes of economic subjects in each cycle. © IJERE. All rights reserved

Increasing the mechanical properties of recycling can be done by adding natural fibers into composite materials. The focus of this research is to develop a composite using bamboo as a reinforcing material and recycled High Density Polyethylene (HDPE) as a matrix using the extrusion method. This study aims to analyze the mechanical analysis between bamboo fiber-based composites using a pure HDPE matrix and composites using recycled HDPE matrices at a matrix volume fraction: 70%: 30% fiber. Mechanical tests were performed using the tensile testing machine model RAY-RAN Test Equipment M500-50CT with ASTM D 638 standards to evaluate the tensile strength and modulus of the composite. The results showed that the tensile strength and Young’s modulus of bamboo fiber reinforced rHDPE composites were 8.764 MPa and 52.0152 MPa, respectively. While the bamboo composite with a vHDPE matrix has a tensile strength of 9.3312 MPa and a Young Modulus value of 94.8468 MPa. Thus, bamboo fiber reinforced composites with pure HDPE matrix have better mechanical properties than bamboo composites with recycled HDPE matrices. Differences in matrix shape can affect composites resulting from such fibers.

Era digital membawa perubahan dalam kegiatan perdagangan. Kegiatan perdagangan yang tadinya dilakukan secara konvensional menjadi daring dalam pelaksanaannya. Perkembangan transaksi di pasar digital menjadi lebih banyak di era pandemi Covid-19. Kegiatan tersebut membawa implikasi terhadap pelaksanaan pengawasan persaingan usaha yang dilakukan oleh Komisi Pengawas Persaingan Usaha (KPPU). Undang-Undang Nomor 5 Tahun 1999 tentang Praktik Monopoli dan Persaingan Usaha Tidak Sehat belum mengakomodir penegakan hukum terhadap pelaku usaha di pasar digital. Penulisan bertujuan untuk; pertama, mengetahui dan menganalisa pengaturan persaingan usaha tidak sehat dalam pasar digital di Indonesia. Kedua, untuk menganalisa peran KPPU dalam melaksanakan pengawasan terhadap persaingan usaha yang tidak sehat di pasar digital. Penelitian ini dilakukan dengan jenis penelitian kualitatif dengan pendekatan yuridis normatif. Pengaturan persaingan usaha tidak sehat di Indonesia diwujudkan dalam Undang-Undang Nomor 5 Tahun 1999 tentang Larangan Praktik Monopoli dan Persaingan Usaha Tidak Sehat. Dalam mengakomodir pelaksanaan perdagangan melalui sistem elektronik, Indonesia mempunyai PP Nomor 80 Tahun 2019 tentang Perdagangan Melalui Sistem Elektronik. Dalam Praktiknya, peran KPPU kurang maksimal dalam melakukan penegakan dan pengawasan di pasar digital, terutama terhadap pelaku usaha luar negeri aktif yang mempunyai dampak negatif terhadap Indonesia. Urgensitas terhadap pembentukan Undang-Undang Pasar Digital adalah untuk menerapkan prinsip ekstrateritorial dan menguatkan peran KPPU.

The study want to explain the maening of "I have not got hidayah" which is spoken by Basuki Tjahaja Purnama (BTP). For some Muslems these utterence mean positive, therefore, it give simpatic for non_muslem’s speaker.To explain othe meaning of a certain utterence need a language analisys callad Discourse Analysis or Pragmatic Language Analisys (PLA). PLA is a study about the use of language which try to elaborate language, spoken or verbally with its contex. The basic concept of PLA as explained by Wijana is Spoken’s contex, spoken’s act, Implicatu, Principle of teamwork, and unpolitely. Discourse Analisys is comphrenship analisys to understand the spoken’s utterence which make some mis understanding.The results shows those utterence is just to guide some opinions of the listeners in order to act casually to Islam. It is not get some simpatic.
