Abstract

Purpose: The aim of community service (PKM) is to empower and increase awareness of the entire academic community towards plastic waste. Research methodology: This PKM was carried out at Botanical Garden FPMIPA UPI. In order to maximize this activities, partners, namely the Himelnah Ciparay Community, Bandung Regency is invited. The method is followed by giving a lecture and workshop to 30 students These activities consists of (a) data survey on the use of tumblers in campus, (b) socialization and education about plastic waste and its risks, (c) collecting plastic bottles in the campus area, (d) recycling plastic bottles into ecobricks, (e) manufacture of products made from ecobricks and (f) feedback and responses from PKM activities. Results: After these activities, there were some changings such as improvement in students/people awareness level about plastic wastes; plastic bottles were collected in properly container (daily) at FPMIPA campus; water refill is facilitated at FPMIPA campus in order to minimize bottle plastics. Limitations: The limitation of this program is the number of volunteers who are not too many willing to be involved to take part in this event. Contribution: The contribution of this program includes instilling the habit of zero waste lifestyle to students to bring into their life, and also reducing the volume of plastic waste and preserving nature.

Abstract

Information security becomes very important as long as information technology continues to develop. This research combines Shamir Secret Sharing (Scheme ( , )) cryptography and Least Significant Bit (LSB) steganography to improve information security in the aspect of confidentiality. The need to collect a minimum number of shares, Scheme ( , ) method makes it more difficult for hackers to reconstruct the message. The implementation of the combination of cryptography and steganography produces an application program created with Python programming languange version 3.11.2, where the Scheme (t,w) used is and RGB image as the cover object of LSB method. In determining the location of image pixels that will be inserted into the message, random numbers generated by the Linear Congruential Generator (LCG) algorithm is used. The program can create a share of text messages with a maximum of 8 characters contained in ASCII characters 32 to 126. The result obtained from the share construction program is QR codes that refers to the stego image that has been inserted by the share, so that the existence of information in the QR code is difficult to know. The program can also reconstruct the message back from QR codes.

Abstract

Tujuan penulisan artikel ini yaitu untuk mendeskripsikan kegiatan PkM berjudul Seminar Multimedia Interaktif untuk Guru Matematika. PkM ini menggunakan model pelatihan Goad, yaitu 1) analisis kebutuhan pelatihan, 2) desain pendekatan pelatihan, 3) pengembangan materi pelatihan, 4) pelaksanaan pelatihan, dan 5) evaluasi dan pemutakhiran pelatihan. Bentuk kegiatan PkM ini, yaitu seminar untuk guru matematika SMP di Kota Bandung dan implementasi pada siswa kelas VIII. Tempat pelaksanaan PkM adalah SMP LabSchool UPI dan Program studi Pendidikan Matematika Fakultas Pendidikan Matematika dan Ilmu Pengetahuan Alam di Universitas Pendidikan Indonesia. Instrumen yang digunakan pada seminar dalam rangka PkM ini adalah angket guru. PkM telah dilakukan melalui implementasi media pembelajaran Scratch pada siswa kelas 8 SMP dan seminar dengan 6 buah pengembangan materi, yakni Scratch, Google Form, model-model pembelajaran, Kahoot, Quizizz, dan Liveworksheets yang diikuti oleh kurang lebih 100 peserta. Hasil dari PkM ini, yaitu kegiatan berjalan baik dan bermanfaat bagi guru matematika serta diharapkan dapat diadakan secara rutin. Dengan demikian, perlunya program lanjutan untuk meningkatkan pengetahuan dan keterampilan guru.
